Adjustment After the roller bearing is installed in the server, if the axial vibration of the spindle spherical roller bearing is accurately measured, it can be found that the measured value of each revolution has a certain change; when the accurate measurement is continued, it can be found that the After a certain rotation speed, this change will occur repeatedly in a similar manner. The index value to consider the degree of this change is the rotation accuracy of the circulation system. The rotation speed that changes similarly and repeatedly produces the required rotation speed represents the “quasi-periodic time” of the rotation accuracy of the circulation system. The largest numerical change amplitude within the quasi-periodic time is, The rotation accuracy of the circulation system is poor. For example, the spindle spherical roller bearing is excessively preloaded in many aspects, and the speed ratio is gradually increased to a cutRW Escorts close to the task direct speed ratio , in order to implement the “running-in period” function of the spherical roller bearing, which can improve the rotation accuracy of the circulation system of the spindle spherical roller bearing.
2. The fixed distance distribution of steel balls improves the accuracy of spherical roller bearings
A factory develops instruments RW Escorts, the main shaft spherical roller bearing uses 6202/P2 type spherical roller bearing but its accuracy still cannot meet the requirements, the font at the back of the motor is bold The shaft and a dovetail guide rail are made on it to replace the inner hole, and the steel balls are measured with high precision and the specifications are divided into groups of three. Each group of steel balls is separated by a distance of nearly 120°. In addition to the production and processing surface, a layer of mutual similarity has been reduced, and the bending stiffness of the spherical roller bearing system at the entrance of the shaft has been improved. The close fixed distance distribution of the large three-grain and small three-grain steel balls has also improved the The rotation accuracy of the shaft is improved, thus meeting the accuracy requirements of the instrument.
3. Comprehensive calibration method for installation accuracy
After installing the spherical roller bearing into the spindle spherical roller bearing, The procedure for checking the installation accuracy is as follows (taking a CNC lathe with a journal of 60Ф100 mm as an example):
(1) Accurately measure the specifications of the shaft and the spherical roller bearing seat hole to understand the characteristics of the spherical roller bearing The common accuracy and common rules are as follows: The inner hole and the shaft adopt a transition joint, and the interference amount is 0~+4μm (0 at light load and high precision); the outer side and the spherical roller bearing seat hole adopt a transition joint, and the clearance is Measurement 0 ~ +6μm (but when using angular contact ball spherical roller bearings at any end, the space can be expanded); the surface concentricity error between the shaft and the seat hole is less than 2μm, imported spherical rollers The three-dimensional Rwandans Escort inner hole of commonly used spacers for bearings is less than 2 μm, and the inner hole of the shaft ring is open to the outside. The vibration of the inner hole is less than 2 μm. ; The vibration of the spherical roller bearing seat hole shoulder to the center line is less than 4 μm; the inner end of the spindle spherical roller bearing front cover should be less than 4 μm against the center line.
(2) Front adjustment of the fixed end. Installation of spherical roller bearings on the shaft
Clean the spherical roller bearings with clean cleaning gasoline. For grease lubrication, first introduce a solvent containing 3% to 5% lubricating grease into the spherical rollers. After the bearing is deoiled and cleaned, use Rwandans Sugardaddy cooking oil gun to fill the spherical roller bearing with quantitatively analyzed lubricating grease (accounting for adjustment). 10% to 15% of the indoor space capacity of the spherical roller bearing); heat the spherical roller bearing to increase the temperature by 20 to 30°C, and use a hydraulic press to install the spherical roller bearing into the spherical roller bearing end cover; tighten the The fixed sleeve is pressed on the shaft and pressed against the inner hole of the spherical roller bearing with appropriate working pressure to accurately position the radial Rwanda Sugar ; Wrap the strap of the spring scale around the outside of the spherical roller bearing, and check the required preset by accurately measuring the running torque.Does the load change significantly (even if the spherical roller bearing is suitable, the preload is likely to change due to mutual coordination or deformation of the ball spherical roller bearing).
(3) Install the spherical roller bearing shaft assembly into the seat hole.
Heat the seat hole to increase the temperature by 20 to 30°C, and use continuous and light working pressure to press the spherical roller bearing? Install the shaft assembly into the seat hole; adjust the front cover so that the tightening amount of the front cover is 0.02~0.05μm. Using the outer and inner holes of the spherical roller bearing seat as the standard, arrange the micrometer head on the surface of the motor shaft. Rotate the shaft to accurately measure the vibration, the standard error is less than 10μm; position the micrometer on the shaft, align the meter head with the surface of the back seat hole, rotate the shaft to accurately measure the front of the spherical roller bearing seatRwanda Sugar Daddy The parallelism of the rear left and right seat holes.
(4) Any end spherical roller bearing can be selectively placed in a part where the error is likely to be offset Rwandans Escort position, install it to the supporting part behind the spherical roller bearing seat, and try to compensate for the concentricity error and linearity error between each other.
4. Installation of double-row short cylindrical roller spherical roller bearings with tapered holes
Installing NN3000K series products with double-row short cylindrical roller spherical roller bearings with tapered holes When installing spherical roller bearings, you must pay attention to the appropriateness of the inner diameter of the imported spherical roller bearing and the brightness of the shaft. When the total output is small, you can use the color painting method for touch inspection, but during production When children make large quantities, use high-precision brightness cards to check. When installing the inlet spherical roller bearing on a tapered shaft, the inner hole should be adjusted to the excessive position in the radial direction so that the axial backlash is close to zero.
