The correct installation techniques of TIMKEN bearing method of replacement

Whether the bearing should be the repair concrete judgment method, namely TIMKEN bearings have make full use of the near destruction of specific judgment method is as follows: 1) Using bearing working condition monitoring instrument using SPM or I - such as iron spectrometer ID— Type 1 bearing working condition monitoring instrument to determine the working state of bearing and decide when bearing should be the repair, this is the most convenient and reliable method. For example, when using the HD - Type 1 instrument, when a pointer by warning area close to the danger zone, and after the measures such as to improve the lubrication pointer has not returned, can be ascertained and the bearing itself, can take at this time has not yet come into the danger zone, the bearing repair service. Exactly how far away from the danger area began to repair, can be adjusted by the experience. Use of such instruments, can make full use of bearing working potential, and in a timely manner to the bearing repair service, and can avoid failure, is safe and economic. 2) Using simple tools to monitor in does not have the occasion of the instrument, the operator can hold or wrench tools such as conflict of round the most close to the TIMKEN bearing machine shell parts, ashamed of tools to monitor the ear tool by the sound of bearing operation, using a stethoscope modification can also, of course. Normal working of TIMKEN bearings should be uniform, smooth, not harsh voice instead of the normal working of bearing has a wide variety of intermittent, impact or harsh voice. First have to get used to the normal working of bearing ring, and then you can grasp the judgment is not normal working of bearing, and then through the accumulation of practical experience, and further can analyze what kind of what kind of bearing abnormal sound corresponds to the abnormal phenomenon. Bearing abnormal sound of category a lot, it is difficult to talk, mainly by experience accumulated. ( 1) Work together as much as possible through the axis of the bearing, this requires the screws even symmetry and smooth, by spherical or parallel to the axis force application. ( 2) Wire should be smooth and uniform, the size of the unfavorable impact, this request can use hydraulic or use steady pull or pressure tool, it had to use hammer, also want to through soft without exfoliation metals such as copper sleeve to buffer, tapping force as gently as possible. It is best to use copper or copper hammer hammer. ( 3) Avoid by applying pressure roller, which requires the inner ring (installation Axial circle) When applying pressure through the inner ring and outer ring installation) Through the outer power works. ( 4) The extent of the drag force continued to be, for example, when installing a TIMKEN bearings in the bearing fit into the correct position to stop work, guarantee the ring ( Washers) The end face of landing on a hole or shaft shoulder end, neither packed too tight, nor does not reach the designated position.
