How do I install tapered roller bearings?

Views: 0     Author: Site Editor     Publish Time: 2022-06-10      Origin: Site

Tapered roller bearings consist of inner ring, outer ring and tapered rolling elements. Due to their design geometry, tapered roller bearings can accommodate combined loads (axial and radial). In addition, this design allows the rollers to continue rolling even if the rollers slide on the outer and inner raceways.

How do I choose and install a suitable tapered roller bearing?

The outer ring of the tapered roller bearing and the housing bore of the bearing housing should not be used simultaneously with the inner ring and pin and should not be tightened too tightly. When mounting the nut, it should be adjusted to create a more flexible axial displacement. Since the change of bearing contact angle is affected when the tapered roller bearing is used, there can easily be a high temperature rise caused by the uneven distribution of bearing load. Therefore, the inner and outer rings of this bearing type and the housing holes of the spigot and housing are generally pressed into the spigot with both hands and thumbs, and the housing hole is the best hole.



How to set the adjustment axial clearance of tapered roller bearings?

When installing tapered roller bearings, the axial clearance can be adjusted by adjusting the nut on the pivot, adjusting the disc and bearing seat thread or by using a preloaded spring. The axial air is the bearing dimension in the installed state. The distance between bearing, shaft and bearing can be determined according to the operating conditions. When adjusting the clearance for high load, the high-speed tapered roller bearing must compensate for the influence of the temperature rise on the axial clearance. For slow running and vibrating bearings, backlash-free or pre-assembled fixtures should be used. The purpose is that the roller and raceway of tapered roller bearing produce good contact load and distribute evenly, preventing the drum and drum from being damaged by vibration. Check the size of the set axial clearance with a gauge. The method is to apply the first micrometer to the body or housing, with the shiny surface of the micrometer touching the shaft against the shaft. The maximum permissible amount of the axial needle is the axial clearance value.



Why carry out commissioning and temperature testing of tapered roller bearings?

To ensure that the rollers of the tapered roller bearing have good contact with the raceways and obtain a suitable axial clearance, the secondary bearings should be tested and tested after each adjustment of the clearance. The method is to first work for 2-8 minutes at low speed, then perform a speed test for 2-hours, and then gradually go to high speed. The test run at any speed must not last less than 30 minutes and the heating rate must not exceed 5°C/hour and the stable final temperature must not exceed 70°C. In addition, when installing and adjusting tapered roller bearings, it is important to note that good contact between the tapered roller and the large flange of the ring is required.
