Turntable bearing is a kind of large bearing with a variety of functions, such as supporting, rotating, driving and fixing, which can bear large axial load, radial load and overturning moment at the same time. Therefore, when installing the rotating disc bearing, we must do a good job of checking the correlation, or the matters needing attention when installing. For this kind of large bearing, we must do a good job of maintenance and storage so as to avoid the following damage of the turntable bearing, which can not be used normally.

 

 

Before the turntable bearing is installed, the installation surface of the main engine must be checked first, and the support should have enough strength, the connection surface should be machined, and the surface is smooth without sundries and burrs. For the degree of planeness that can not be machined to meet the required flatness, a special plastic injection with large injection strength can be used as a filler to ensure the accuracy of the installation plane and to reduce vibration. The ring bearing ring has a quench zone, which is marked "S" on the end of the ring. The position of the belt should be placed in a non - load or non - regular load area (the plug is always located in the soft zone).

When installing the turntable bearing, it should be positioned in a radial direction, tighten the bolt and tighten the rotation of the bearing. When tightening the bolt, there should be enough pre tightening force, and its pretightening force should be 70% of the yield limit of the bolt material. Installation of bolts should be equipped with quenched and tempered flat washers and no use of spring washers.

Maintenance of turntable bearing: after 100 hours of continuous operation, the pre tightening torque of the installation bolt should be fully checked to meet the requirements. After 500 hours of continuous operation, the above inspection should be repeated every time. After installing the turntable bearing, proper grease should be filled, and the slewing bearing should be filled with side to make the grease distribute evenly. After working for a period of time, the turntable bearing will inevitably lose a part of the grease. Therefore, a lubricating grease should be supplemented once every 50~100 hours after each interval in the normal running of the turntable bearing.

Transport and storage of turntable bearings: bearings should be placed horizontally on vehicles during transportation, and measures should be taken to prevent sliding and prevent vibration, and supplementary support should be added when necessary.
