The installation of rotary bearing - bearing knowledge

1 wheel bearing installation turntable bearing before installation, check the mounting surface of the host first, request support should have sufficient strength, junction surface should be mechanical processing, surface is flat debris and burrs. Mechanical processing for unable to meet the requirements of planeness, can use special plastic filler injection intensity, to ensure the accuracy of the installation plane and for vibration reduction. Wheel bearing ring with quenching soft belt region, in the ring on the face of all marked 'S', when installation should be in the position of the soft belt on the load area or not often load area ( Plug hole is always located on the soft belt) 。 Installing a wheel bearing, should be advanced ways to locate, cross tighten mounting bolts, and monitor the rotation of the bearing. And tighten the screw down the bolt should be enough, it shall be the bolt pretightening material yield limit of seventy percent. Install bolts should be with conditioning flat washer and spring washer is strictly prohibited. 2 wheel bearing maintenance is installed and functioning of the wheel bearing after the continuous running 100 hours, should be a comprehensive check installation bolt pre-tightening torque is in line with the requirements, after each repeat this check a continuous run of 500 hours. Wheel bearing installed should fill the right amount of grease, and should be filled and slewing bearing with grease evenly distributed. Wheel bearing at work after a period of time, will inevitably lose part of grease, so the wheel bearings in normal operation intervals of 50 ~ 100 hours after a grease should be added. 3 wheel bearings, transport and storage of bearing in the process of transportation, should be placed on the vehicle, due to prevent sliding and the measures to prevent vibration, plus auxiliary support when necessary.
