Clearance control of german ball bearings:
Aiming at the problem that radial clearance is controlled by axial clearance and radial clearance is out of tolerance after bushing in the production of german ball bearing, by strictly controlling the accuracy of internal and external channel and steel ball, and compressing the radial clearance range when calculating axial clearance, the lower limit remains unchanged and the upper limit is compressed by 15%.The axial clearance obtained by this method is used as the reference to control the actual radial clearance after the casing is closed.
German ball bearings are used in machines and equipment with rotating parts.Designers often have to decide whether to use german ball bearings or fluid film bearings for specific applications.The following characteristics make german ball bearing more desirable than fluid film bearings in many applications.
1. Small starting friction and suitable working friction.
2.Able to withstand combined radial and axial loads.
8. Not sensitive to the interruption of lubrication.
4. No self-excited instability.
5. Easy to start at low temperature.
Within a reasonable range, changes in load, speed and operating temperature have only a small effect on the good performance of german ball bearings.
The following characteristics make german ball bearings less desirable than fluid film bearings.
1. The finite fatigue life changes greatly.
2. Larger radial space is required.
3. Low damping capacity.
I. High noise level.,
6. Strict requirements.
6. High cost.
As a result, piston engines typically use fluid film bearings, whereas jet engines almost exclusively use german ball bearings.All types of bearings have their own advantages, in a given application, should be carefully selected the most appropriate type of german ball bearingsThe British engineering science data organization (ESDU 1965, 1967) provided useful guidelines for the important question of german ball bearings selection.
