(2) Check the size and finishing of relevant parts;
(3) Installation;
(4) Inspection after installing the spherical roller bearing;
(5) Supply lubricants20240925/25318
120240925/25318 Alignment and alignment
After the spherical roller bearing is installed, ifIf not done carefully, alignment can cause the spherical roller bearing to encounter additional loads, friction and vibration20240925/25318 These can accelerate fatigue and reduce the service life of spherical roller bearings, and may destroy the service life of other mechanical parts20240925/25318 Additionally, increased vibration and friction can significantly increase power consumption and risk of premature failure20240925/25318
220240925/25318 Basic condition monitoring
During use, the basic internal conditions of the operation of the centering roller bearing must be monitored frequently, such as temperature, vibration and noise measurement, etc20240925/25318 These disciplined reviews will identify potential problems early and will prevent unexpected Rwandans Sugardaddy machine interruptions, allowing the plan to have a baby Complete, improved factory productivity and efficiency20240925/25318
320240925/25318 Re-lubrication
During operation, spherical roller bearings require correct re-lubrication to improve its performance20240925/25318 The lubrication methods of spherical roller bearings are divided into grease lubrication and oil lubrication20240925/25318 In order for the spherical roller bearing to perform well, first of all, it is necessary to choose a lubrication method suitable for the application conditions and application objectives20240925/25318 If we only consider lubrication, the lubricity of oil lubrication prevails20240925/25318 RW Escorts is grease lubrication and has expertise in simplifying the surrounding structure of spherical roller bearings20240925/25318
420240925/25318 Removal
When the spherical roller bearing reaches its end use period, it should be replaced20240925/25318 Although the spherical roller bearings can no longer be used, correctly removing the original spherical roller bearings and replacing them with new ones in a timely manner can greatly extend the service life of the new spherical roller bearings20240925/25318 Good promotion effect20240925/25318 The proper methods and techniques for removing spherical roller bearings and the use of tools will help in the maintenance and repair of spherical roller bearings in other machines20240925/25318
What are the Rwandans Escort heating methods?
The preload force of the spherical roller bearing is carried out at room temperature, but in the working state, the system slightly stretches the drive shaft caused by the temperature rise, and the bearing preload force will change20240925/25318 Therefore, the setting The preload force should take this reason into account20240925/25318
It requires the reasonable use of spherical roller bearing preload capable of size, speed, and other condition settings to ensure transmission life20240925/25318 If the preload force is too large, it will consume power and even cause overheating20240925/25318 If the preload force is too small, the body load, shaft rotation, and the gap between the outer rings will cause jumps and runs, which will increase the transmission accuracy and reduce the noise, affecting the gear meshing and causing serious damage to the teeth and bearings20240925/25318
According to different spherical roller bearing disassembly, such as: directly axially compressing the inner bearing inner ring of the bearing preload nut and rotating the inner and outer rings to eliminate the gap and complete the installation20240925/25318To achieve the goal of bearing preload force20240925/25318 Complete fit application: first, far across the pre-installed bearing, last with nut, then back 1/4 turn20240925/25318 Second, the advantages of this assembly method are low investment, simplicity, and practicality20240925/25318 Nuoboxuan Axis recognizes that as long as the roller bearings are ensured under good quality conditions, several methods can be used for heating20240925/25318 20240925/25318
120240925/25318 Electric hot plate heating method20240925/25318 Place the bearing on an electric hot plate with a temperature of 100°C for a few minutes20240925/25318 This method is the simplest20240925/25318 If you turn it over several times, the shaft can be heated evenly, and the efficiency is also high20240925/25318 This method can be applied to spherical roller bearingsRwandans Sugardaddy20240925/25318
220240925/25318 The electric furnace heating method places the bearings in a closed automatic temperature-controlled electric furnace for heating20240925/25318 The heating is even, the temperature control is accurate, and the heating is fast20240925/25318 It is suitable for occasions where many bearings are heated in a batch20240925/25318
320240925/25318 Induction heating method20240925/25318 The use of induction heaters can quickly, reliably and cleanly heat the spherical roller bearings to the required temperature20240925/25318 This is especially suitable for places where the inner rings are tightly matched, because the heated Only the inner ring is heated, and the outer ring is rarely heated20240925/25318 This makes it easier to install on the shaft and not difficult to install into the seat hole20240925/25318
420240925/25318 Electric light bulb heating method, using a 50W electric light bulb to heat the spherical roller bearing, can ensure that the heating temperature is around 100°C20240925/25318 Smaller bearings can be placed directly on the light bulb, and larger bearings can be placed on the light bulb20240925/25318 Inside the cone-shaped cover of the lamp, the cone-shaped cover can prevent the heat loss of the lamp and make the heating even20240925/25318 The cone-shaped cover can be adjusted up and down to adapt to the heating of bearings of different sizes within a certain range20240925/25318 If a far-infrared lamp is used, please note that The direction of the light bulb should be downward to prevent infrared rays from being harmful to human eyes20240925/25318 This kind of light bulb can be used with energy-saving light bulb heating methods for small numbers that are not often needed; the light bulb can also be used in places where bearings need to be heated20240925/25318 For lighting purposes, no other equipment is required20240925/25318
520240925/25318 Oil tank heating method, this is a widely used traditional heating method20240925/25318 A metal mesh is set 50~70mm away from the bottom of the oil tank, and the bearings are placed on the mesh20240925/25318 Large bearings need to be lifted with hooks, and the bearings should not be placed directly on the The bottom of the tank to prevent the bearing parts that contact the bottom of the tank from being overheated, or the dirt settled at the bottom of the tank to enter the bearing oil tank20240925/25318 The key points to note when heating the oil tank are as follows20240925/25318 Non-corrosive mineral oil with good thermal stability should be used, preferably Transformer oil, oil and container should be kept clean20240925/25318 The capacity of the oil tank should be determined by the size and oil volume of the heated spherical roller bearing20240925/25318 If the container is too small, the oil temperature will rise quickly as soon as the bearing is put in during continuous operation20240925/25318 If it falls, the consequences will be bad20240925/25318
Gain common sense! Operational inspection skills after bearing installation
After the installation of the spherical roller bearing, in order to check whether the installation is correct, a running inspection must be carried out20240925/25318 Whether the installation of the spherical roller bearing is correct will affect the operating accuracy of the later machinery20240925/25318 It has a lot to do with the service life of spherical roller bearings20240925/25318 Therefore, it is very necessary to check the operation of the spherical roller bearing after installation20240925/25318 So what are the techniques for testing different machines?
120240925/25318 Small machinery
Small machines can be rotated by hand to confirm whether they rotate smoothly20240925/25318 Inspection items include poor operation caused by foreign matter, scars, and indentations, uneven torsional torque caused by poor installation and poor machining of the mounting base, large torque caused by too small clearance, installation errors, sealing friction, etc20240925/25318 20240925/25318 If there is no abnormality, the power operation can be started20240925/25318
220240925/25318 Large machinery
Since large machinery cannot be rotated manually, the power must be turned off immediately after starting without load, stop inertial operation, and check for vibration, sound, and whether the rotating parts are intact20240925/25318 Contact, etc20240925/25318, and then proceed to power operation after confirming that there is no abnormality20240925/25318
Power operation starts from no-load low speed and gradually advances to the specified operating conditions20240925/25318 The inspection items during the trial operation are whether there are abnormal sounds, temperature changes of the spherical roller bearings, leakage and discoloration of lubricant, etc20240925/25318 If any abnormality is found during the trial operation, the operation should be stopped immediately, the machine should be inspected, and the spherical roller bearing should be removed for inspection if necessary20240925/25318
The temperature inspection of spherical roller bearings can generally be predicted from the surface of the shell20240925/25318 However, it is more accurate to use the oil hole to directly measure the temperature of the outer ring of the spherical roller bearing20240925/25318 The temperature of the spherical roller bearing starts to rise gradually during operation20240925/25318 If there is no abnormality, it usually stabilizes after 1 to 2 hours20240925/25318 If the spherical roller bearing or installation is defective, the temperature of the spherical roller bearing will rise sharply and appear abnormally low20240925/25318 The reasons include too much lubricant, too small clearance of spherical roller bearings, poor installation, excessive sealing device friction, etc20240925/25318 In places of high-speed rotation, incorrect selection of the lubrication method of spherical roller bearings is also the reason20240925/25318
The above is the inspection skills of Nuoboxuan spherical roller bearings for the operation of centering roller bearings20240925/25318 Spherical roller bearings are very important parts in modern machinery and are important for the normal operation of machinery20240925/25318 Especially due to the influence of the impact, the inspection after the installation is also very important in the daily process20240925/25318
Bearings must be selected and used in this way to “prescribe the right medicine”
In fact, when it comes to spherical roller bearings, everyone may have a feeling that is both unfamiliar and familiar, because we all know that spherical roller bearings are Why, but few people have seen the “real face” of spherical roller bearings20240925/25318 But there are many places in our lives that require spherical roller bearings, such as wheels20240925/25318 Spherical roller bearings can be used in everything from high-end toy cars to bicycles, motorcycles, and cars20240925/25318 Electric fans, exhaust fans, range hoods, and air conditioners are also available20240925/25318 There are many examples to name, so if there is a problem with the spherical roller bearings in these household appliances, how should we choose the appropriate spherical roller bearings? Tomorrow, the editor of Noboxuan will introduce to you how to select a pair of spherical roller bearings~
120240925/25318 Unique choices
The inner diameter and outer diameter of the spherical roller bearings are Manufactured according to standard tolerances, the consistent tightness of the inner ring of the spherical roller bearing with the shaft, outer ring and seat hole can only be achieved by controlling the tolerances of the journal and the seat hole20240925/25318 The inner ring of the spherical roller bearing and the shaft use the base hole system, and the outer ring and the seat hole of the spherical roller bearing use the base shaft system20240925/25318
YesWhen choosing a suitable spherical roller bearing, you must understand the actual load conditions, operating temperature and other requirements of the spherical roller bearing20240925/25318 In fact, it is very Rwandans Sugardaddy Hard20240925/25318 Therefore, in most cases, the selection is based on application and intensive research20240925/25318
220240925/25318 Load size
The amount of overlap between the ferrule and the Rwanda Sugar shaft or housing depends on the load20240925/25318 Size, heavier loads use larger overshoot, lighter loads use smaller overshoot20240925/25318

What are the real causes of bearing fever?
In industrial childbirth, the use of various mechanical equipment is indispensable20240925/25318 So, under normal circumstances, during the use of the machine, if the temperature of the spherical roller bearing is found to be too high, it will be hot to the touch20240925/25318 In this case, it is usually a machine failure20240925/25318 If it cannot be discovered in time and the correct treatment is not made, it may cause twice the result with half the effort20240925/25318 In more serious cases, it may also cause the service life of the spherical roller bearing to be shortened20240925/25318 Extensions, increased inspection costs, and even the scrapping of spherical roller bearings are all possible events20240925/25318
Therefore, discovering the real cause of mechanical failure in a timely and correct manner and taking appropriate measures to solve the problem are indispensable in equipment operation and inspection20240925/25318 Today, the editor will first analyze a problem in use20240925/25318 The most common cause of heat problems in spherical roller bearings20240925/25318
120240925/25318 Poor lubrication20240925/25318 Poor lubrication has a major impact on the service life and friction, wear, vibration, etc20240925/25318 of spherical roller bearings20240925/25318 Good lubrication is a necessary condition to ensure the normal operation of spherical roller bearings20240925/25318 According to statistics, about 40% of spherical roller bearing damage is related to poor lubrication20240925/25318
However, the common reasons for poor lubrication of spherical roller bearings are:
1) Insufficient lubricating oil
2) The lubricating oil pipe is blocked by foreign matter, etc20240925/25318
3) The quality of lubricating oil tools There is a question
4) Lubricating oil is not added on time
5) The lubricating oil contains impurities
220240925/25318 Spherical roller bearing wear
Spherical roller bearings are the main parts20240925/25318 It is used in various large and small machines, and some machines (such as crushers) work in a dusty environment20240925/25318 When part of the fine dust enters the high-speed rotating spherical roller bearing seat, it causes dust in the spherical roller bearing seat20240925/25318 The lubricating oil or grease deteriorates and the lubrication is poor, which in turn causes the spherical roller bearing to wear20240925/25318 Spherical roller bearings continue to operate under wear conditions20240925/25318 Due to the increase in friction and heat, the temperature of the spherical roller bearings decreases20240925/25318
320240925/25318 Improper installation
Improper installation is the cause of alignment20240925/25318 Another important reason for roller bearing fever20240925/25318 due to tuningWhether the spherical roller bearing is installed correctly or not has a direct impact on its service life and the accuracy of the main engine20240925/25318 Therefore, the center line of the shaft and the spherical roller bearing hole must be coincident during installation20240925/25318 If the spherical roller bearing is not installed correctly, the accuracy Rwanda Sugar is low, the spherical roller bearing has deflection, and a torque will occur when it rotates20240925/25318 Cause the spherical roller bearing to heat or wear20240925/25318 In addition, spherical roller bearings will also vibrate, increase noise, and increase temperature rise20240925/25318
420240925/25318 Improper selection of spherical roller bearings
When selecting spherical roller bearings, attention should be paid to the limit speed and load capacity of the spherical roller bearing, and it cannot be used at overspeed or overload20240925/25318 , which will only extend the service life of the spherical roller bearing, and the gain and loss are equal20240925/25318
