TIMKEN bearing Assembly's main task is to put the inner ring, outer ring and body size selection, by matching to ensure that when mounted with radial clearance or meet the requirements of the width. TIMKEN bearing Assembly of a primarily sets of processes with process is selected, first ring raceway diameter dimensions selected subsectors, and various groups of bearings with extended inner ring, outer ring and body according to require clearance or width tolerance together to become "a set" TIMKEN bearings.
TIMKEN bearing ring process, for various reasons, will enable raceway tolerances on dimensions too thinly or offset from Center, and even beyond the scope of the tolerance zone, these problems will reduce the support rate ... To this end, before the matching, inventory of bearing rings should be primaries, have its Raceway dimension of information, and depending on the body size, presented to the grinder operation area supporting parts in a timely manner (inner or outer ring) machining tolerances of the order form. Grinding machine operator jobs in receiving tolerance after the order form, should be made in strict accordance with the tolerances for dimension processing. So, you can increase the TIMKEN bearing Assembly supporting rate.
Election Committee subsector is measured individually supporting the actual size of the Raceway diameter biases deviation in a similar size as a set, and parts are divided into a number of groups. Group size difference of size based on the size of the radial clearance tolerances. In General, ring separating size difference in group by radial clearance tolerances of less than one-third. Considered from the matching precision, fine poor grouping, the better, but because of the conditions of the workplace, poor grouping should not be too small.
1. installation does not allow drilling in the TIMKEN bearings, Groove, chamfer, car faces. Otherwise, prone to deformation of bearing rings, effects of bearing accuracy and life, while cutting out the metal easier access to the bearing working surface, accelerated wear of the Raceway and, bearing causing premature failure.
2. installation does not allow direct beat Bishop TIMKEN bearing rings. Bearing base close to the shaft installed in the end celebration. Base-side surface of the bearing is according to the bearing face without typing to differentiate, deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings, spherical roller bearings and needle roller bearings, based on no words end surface; angular contact ball bearings and tapered roller bearings, based on there face surface.
3. install the pressure should be installed when an interference fit of the ring on the end, that is, when mounted on a shaft, pressure should be added on the TIMKEN bearing inner ring side faces; while loading bearing block hole, the pressure should be on the bearing outer ring side face. Do not allow pass through the body and maintain pressure.
4. tight fit for the inner ring, the outer TIMKEN bearings for facing up, installation, shall be separated should first be on the bearing to the shaft, and then the shaft with bearings into the housing in the shell hole; Division of separable, inner and outer rings can be installed individually.
5. in order to prevent bearing installation tilt when you installed the centerline of the shaft and housing bore must be coincident. If Setup is not straight, when you re-install, must pass the inner ring side face, TIMKEN bearing out of the way.
Main tasks of bearing failure analysis, is based on the large amount of background material, analysis of data and failure modes, find accounted for the TIMKEN bearing failure factors, to formulate improvement measures targeted, roller bearings with extended service period, avoid unexpected early bearing failure.
