The correct use of spindle bearings:
First of all, in the case of bearing housing bearing hole size, shape, accuracy is not good, the bearing will be affected by it, can not play the best performance. For example, if the dimensional accuracy and shape accuracy of the inner hole of the bearing housing are not good, the outer ring of the bearing will be deformed, resulting in deterioration of the roundness of the inner hole of the bearing; if the accuracy of the shoulder is not good, the outer ring of the bearing and the inclination of the roller will be generated, which will increase the concentration. The load will reduce the bearing fatigue life, and more serious will cause the cage to break and sinter; if the bearing of the inner ring of the bearing is not accurate, such as size, roundness, cylindricity, waviness, roughness, position The accuracy of the other aspects will also obviously lead to an increase in the vibration value of the whole set of spindles.
Secondly, the complete set of bearings has undergone strict precision matching before assembly. Therefore, before use, the scattered bearing parts are not interchangeable and can not be used interchangeably.
Third, on the cleaning of spindle bearings and spindles. Due to the compact structure of the spindles, there are many other parts in the spindle cavity, and their cleanliness also affects the cleanliness of the bearing working cavity. Therefore, before the assembly is pre-cleaned with the ingot parts, after the assembly is assembled, the process of finely cleaning the assembly ingots including the bearings is a more reasonable process.
Fourth, the bearing should not be bumped and impacted during assembly. Bump and impact easily cause collision between bearing parts, resulting in bearing failure.
Fifth, when the bearing seat is crimped, care should be taken to control the angle and strength of the crimping to avoid the deformation of the bearing parts caused by unreasonable curling.
Sixth, for bearings that have exceeded the anti-rust period or long storage time, rust may occur or the roller may stick due to dryness of the anti-rust oil.
