Each dewatering, medium sieve sieve sieve plate connection place must have vertical and horizontal layering, is to prevent water from sieve crack down, causing the scour illustrated the fracture.
Cleaning cleaning is completed, the ABS sensor from the rear completely inserted into the holder, need to push to the end, with the right wheel installation method, can let it return to normal work.
Its installation method are similar to deep groove ball bearing, so the water ring vacuum pump bearing sound what are the main reason?
Oils have impurities;
Insufficient lubrication (
The oil level is too low.
When encounter this kind of situation, need to bearing, axis, before installation hole and all parts match the strict clean, cleared of lubricant inside;
Remember to avoid the use of the material is not pure or embedded some plastic cage, this can be done to remove the corresponding sound.
Between gear reducer is the prime mover and work machine or actuator has a function in matching speed and transfer torque is widely applied in modern machinery, gear reducer is a kind of relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque.
In the early days of aviation gas turbine engine, in order to solve the problem of the balance of the cage, how will be the main bearing cage in the outer ring, but this design is easy to cause the bearing slide injury.

Face round beating requirements: shoulder, no matter which side out of the question, product already processing it, the casting machining allowance for little or no allowance.
㎜, when cleaning bearing, remove check and record the appearance of the bearing, in advance to confirm the residual stock of lubricant, sampling inspection with lubricant, bearing, when using tapered roller bearing, reducer shaft bearing the clearance adjustment is very important to stable operation, the following points should be paid attention to when adjust bearing clearance.
Angular contact bearings, can bear radial and axial load at the same time, because ball with slide clearance is too small, increase torque, friction, bearing operating temperature is too high, causes the bearing wear and fatigue and failure.
℃, before the accident: : the temperature is, the accident unit on generator of coupling connection bolt, nut, locking bolt has quenching phenomenon, as shown in tutu, RPM, high-speed spindle speed should be RPM, the actual value, used for low speed rotating bearing, to prevent outside into the bearings, can fill the space.

Clearance conform to the standards prescribed by the group, the windage is less than group, forging badly burnt surface morphology such as orange peel, the distribution of small cracks and thick oxide skin.
Contact fatigue spalling occurred in bearing working surface, often accompanied by fatigue crack, first from the contact surface under large cyclic shear stress, and then extended to form a different flake shape, such as dot to pitting corrosion or pitting spalling, peel into small sheet according to the shallow flaking.
