In the selection of imported bearings; bearings tend to think; the number of smooth fats in the onset of seizures; the fat of the fatigue life; wear; noise. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
In addition; based on different uses; it is necessary to select the accuracy; clearance; insist on the layout; smooth grease and Other aspects of the requirements; uniquely depicted bearings. However; the selection of bearings does not have a certain order; rules; priority should be given to TIMKEN The conditions required for imported bearings; functions; and related matters; unique is useful. Just in order to adhere to the original function of the bearing as much as possible; to adhere to; protect; in the first place; to avoid trouble; to ensure the reliability of work; Productivity; economy. Corresponding mechanical operation and repair work specifications; timing; the best conditions. Including monitoring work conditions; making up or replacing smoothing agents; timing inspection and eradication. As a protection operation problem; TIMKEN bearing transformation sound; ; temperature; smooth conditions; and so on.
Bearing removal: remove the bearing correction; first record the appearance of the imported bearing; recognize the remaining amount of the smoothing agent; use the smoothing agent after the sample inspection; remove the bearing. As a scavenger; usually use gasoline; kerosene. remove the bearing to remove ; clear and fine wash; thick; placed in the container; put the bottom of the metal mesh; make the container that does not directly touch the dirt of TIMKEN imported bearings. rough wash; if the bearing rotates the dirt; damage the bearing rolling surface; should pay attention. In the removal of crude oil; with a brush; to remove grease; viscous information; usually hygienic; washed into fine. Fine washing is the transformation of the oil on one side of the bearing; one side carefully removed. In addition; the removal of oil is necessary to adhere to hygiene.
Bearing repair and discrimination: To determine whether it can be used for sanitary inspection of bearing disassembly bearing. View raceway; raceway; appearance; cage wear; import bearing clearance and scale accuracy progress; irrelevant damage; abnormal. Do not leave small ball bearings; inner ring; with one hand support level; rotating outer ring recognizes smooth. Tapered roller bearings and other off-the-way bearings; can roll the body; outer ring raceway appearance was viewed. Large bearings; Can not be rotated by hand; pay attention to the rolling track of the rolling body; adhere to the frame; wall; such as the appearance; the importance of the higher TIMKEN imported bearings; to be more careful to view.
Trouble and deterioration of TIMKEN bearings; functional status parameters to identify and guess the reliability and function of the bearing; identify and discriminate the location of the abnormal situation; the cause and degree of risk; comprehensive skills for resolution correction and improvement methods. The fault diagnosis skills of bearings are not pure fault detection (or monitoring) skills; nor are they simple external inspections. Collect signals correctly, agilely and effectively; data processing; manual or automatic identification and discrimination. In order to determine the scientific repair cycle It should also be based on the mechanism of various faults; carry out the necessary experiments and budget for fatigue and wear life.
TIMKEN imported bearings can be judged; mainly to consider the degree of bearing damage, mechanical function, importance, working conditions, to the time of the next inspection and resolution. If there are the following shortcomings can not be used; it is necessary to replace the new bearing. There are cracks or notches on either the inner ring, the outer ring, the roll body, or the holder.
1. There is crack on any one of the ferrule and the rolling body.
2. There are significant card injuries on the rolling track, ribs and roll.
3, adhere to the frame wear is significant, perhaps the rivet is significantly relaxed.
4. There is rust on the raceway surface and the rolling body; there is injury.
5. There are severe indentations and marks on the raceway surface and the rolling body.
6, the inner ring inner diameter surface or the outer ring outer diameter surface has significant creep.
7, the color change due to heat is significant.
8, TIMKEN bearing sealed with smooth grease; damage to the seal or dust cover is significant.
