Can be seen from the whole repair process, the whole process is very simple and quick repair sauvy industry, without tedious process steps and a large number of tools, but many details need to strictly control the repair process, fast repair time and repair equipment installed quickly after the boot.
Venus mechanical suggest broad user, reinforced shredding machine equipment operation process, bearing temperature and bearing parts of noise, to timely treatment, what reason can form bearing heating phenomenon of the present?
Reinforced torn oil pipe leakage, lack of oil pressure;
Tubing plugging, poor lubrication grease activity;
Lubricating oil is too dirty, mixed with sundry;
Between bearing and axle space is too small;
Lubricating oil selection is not appropriate, particle size is too big or too small;
Before the winter started didn't open the oil temperature heater, oil too sticky;
In the summer, and from the oil pump oil through the oil cooler, oil cooler or shortcomings, such as poor water pipe plug, water and water;
Bearing cooling water unit faults occur, such as congestion, etc. ;
Discharging mouth a tuning is too small (
The thrust plate is too long)
The eccentric shaft force is too large;
Drive belt pull too tight, the bearing stress is too big.
Low speed with a rolling bearing, high speed, with sliding bearing, the visual difference is high-speed bearing surface more smooth than low-speed bearing, outer ring and inner ring shaking high-speed bearing gap smaller, and low speed, on the other hand.
On bearing life, the key is in haven't failure when to speak and look for customer engineering, quality, SQE, don't look for procurement, procurement don't care why you failed.
Deep groove ball bearings available hand rotation test, in order to smooth and flexible, no vibration, no swinging as well, at this point, the bearing must be unloaded, find out the reason, and reinstall.
Scientists and engineers in line with 'the quantity, the feet, bow ChaYi leakage, all matter, poor raise policy' of the spirit, scientific spirit and craftsmen overcome the material selection, structure design, lubrication design, reliability design, and many other problems, makes the performance of the main bearing extraordinary.
Check shaft position tolerances, and do not conform to the requirements, can't assembly, like the shoulder root radius should be less than the radius of bearing inner ring, in order to make the bearing on shoulder.
Cold rolled the main reducer gear box has its particularity in production process, the two output shaft in synchronous rotating in the opposite direction, the impact of the production process of roll pass to force and torque are quite big, such a case the bearing chamber on the extrusion pressure is big, easy to form the shape of the eccentric wear.
Bearing lubrication grease flows, operating hours, should be replaced, grease filling of oil is too much or too little, because too much or too little will cause bearing grease fever, pitted in bearing chamber volume / -

It is advisable to /.
Coating on surface of the bearing and the bearing lubricating oil, the bearing load bearing, it can withstand ℃ high temperature, but the moment for ℃ or higher temperature will reduce the service life of bearing.
In metallurgy, according to the bearing grinding quality is different, the bearing can be divided into rolling friction bearing (
Referred to as rolling bearings)
And sliding friction bearing (
Referred to as the sliding bearing)
。
This is because when the cage in the outer ring, exists in the oil film between outer ring and cage under the effect of viscosity of obstruction of roll bar cage for normal movement to trigger a skid.
