Timken inlet bearing installation
The fit between the circumference of Timken imported bearing and the shaft is generally a transition fit, and the fit between the race and the Timken imported bearing seat hole is generally a clearance fit. Therefore, this Timken imported bearing is easy to install, and the middle shaft spring of the two-way Timken imported bearing should be fixed on the shaft to prevent rotation relative to the shaft.
The installation method of Timken imported bearing is generally shaft rotation, so the fit between inner ring and shaft is win-win fit, and the fit Inspected After Installation between outer ring of Timken imported bearing and Timken imported bearing chamber is clearance fit.
Inspection of Timken imported bearing after installation. When Inspected After Installation installing Timken imported bearing, check the verticality of shaft ring and shaft centerline.
The method is to fix the dial indicator on the end face of the box shell, make the contact of the dial indicator push on the raceway of the shaft ring of the Timken inlet bearing, rotate the Inspected After Installation Timken inlet bearing, and observe the pointer of the dial indicator. If the pointer deviates, it indicates that the shaft ring and the shaft centerline are not perpendicular.
When Timken imported bearing is installed correctly, its seat ring can automatically adapt to the rolling of Inspected After Installation the rolling element to ensure that the rolling element is located in the raceway of the upper and lower rings. If installed reversely, not only the Timken imported bearing does not work normally, but also the mating surfaces will be seriously worn.
Since the difference between the shaft ring and the seat ring is not obvious, extra care should be taken during assembly. In addition, a Inspected After Installation clearance of 0.2-0.5mm shall be reserved between the Timken inlet bearing race and the Timken inlet bearing seat hole to compensate for the error caused by inaccurate processing and installation of parts.
When the center of Timken inlet bearing ring is offset during operation, this clearance can ensure its Inspected After Installation automatic adjustment, avoid contact friction and make it operate normally. Otherwise, severe damage will be caused to Timken inlet bearing.
The fit between IKO inlet bearing and shaft is generally transition fit, and the fit between seat ring and IKO inlet bearing seat hole is generally Inspected After Installation clearance fit. The middle shaft ring of two-way bearing shall be fixed on the shaft to prevent rotation relative to the shaft.
The installation method of IKO imported bearing is generally shaft rotation, so the fit between inner ring and shaft is win-win fit, and the fit Inspected After Installation between bearing outer ring and IKO imported bearing chamber is clearance fit.
When installing IKO imported bearing, the verticality of shaft ring and shaft centerline shall be inspected. The method is to fix the dial indicator on the end face of the box shell so that the contact of the dial indicator is against the raceway of the shaft ring of IKO imported bearing, rotate the bearing and observe the pointer of the dial indicator.
If the pointer deviates, it indicates that the shaft ring and the shaft centerline are not perpendicular. When the shell hole is deep, it can also be inspected with an extended dial indicator. When the IKO imported bearing is installed correctly, its seat ring can automatically adapt to the of the body to ensure that the body is located in the raceway of the upper and lower rings.
If it is installed reversely, not only the IKO imported bearing does not work normally, but also all mating surfaces will be seriously worn. Since the difference between the shaft ring and the seat ring is not obvious, extra care should be taken during assembly.
In addition, a clearance of 0.2-0.5mm shall be reserved between the bearing race and the bearing seat hole to compensate for the error caused by inaccurate processing and installation of parts. When the center of IKO inlet bearing ring is offset during operation, this clearance can ensure its automatic adjustment, avoid contact friction and make it operate normally. Otherwise, the IKO inlet bearing will be severely damaged.
