When bearings are maintenance, attention there. In the previous article, I also said that other brands of TIMKEN bearings, brand is different, notes are not the same. We are in the process of doing, must pay attention to these issues.
TIMKEN bearing fault feature showed a serious fault of not more than one week of time, equipment, larger, faster, and shorter time intervals. Therefore, the actual bearing fault diagnosis, fault is found, its advanced features, should be bold and determined a spherical roller bearing failure, repair as soon as possible.
1, selection and control of shaft and housing tolerances: after press the bearing into the TIMKEN bearing should be sense of rotating flexible non-blocking. As an apparent rotation is clumsy, it indicates that the dimensions of the shaft is too big, the tolerance to cut.
2, TIMKEN bearing Assembly method: because the bearings are high-precision products, such as improper Assembly can easily cause damage to the bearing Raceway, causes bearing damage.
3, Assembly of foreign body prevent: bearing when mounted to the rotor dynamic balance is easy to produce of iron filings into the bearing dynamic balancing of time inside, so it is best to be done before the load bearing dynamic balancing.
4 Prevention of rust, paint: paint the rust is characterized by multiple sealed-type motor, motor Assembly has a good voice, but after you put some time in the warehouse, abnormal sound of motor and remove the bearing with serious rust.
Bearing in the middle of checking if there are too many problems, as well as these bearings TIMKEN bearings can be faked. Is a reminder at the selected time must be careful.
