Use oil pumping gear maintenance

Reducer bearing disassembly: When removing the rear bearing intends to continue to use, you should use the appropriate removal tool. Removing interference fit of the ring, only added to the tension on the collar, must not be allowed to pass through the rolling force demolition, otherwise the rolling elements and raceways will be crushed.

Bearing Environment: select size, precision and conditions of use according to the use of the site and environmental conditions, with the right bearing is a prerequisite to ensure bearing life and feasible.

1, using the site: tapered roller bearings for joint load to bear radial load mainly radial and axial, usually paired with two sets of bearings, primarily for automotive front and rear hub, active gear, differential , a reducer and other transmission parts.

2, the permissible speed: install properly oiled environment, allowing for bearing 0.3-0.5 times the speed limit. Under normal circumstances, to 0.2 times the speed limit is the most appropriate.

3, allowing the tilt angle: Tapered roller bearings are generally not allowed to tilt axis relative to shell hole, if inclined, to a maximum of 2 '.

4, allowing the temperature: in under normal load, and lubricant high temperature performance, and under conditions sufficient lubrication, bearings generally allowed to work at -30 ℃ -150 ℃ ambient temperature.
