ARotary bearing (also called slewing bearing) is a kind of bearing that can bear large axial load, radial load and overturning force at the same time The large bearing with special structure and comprehensive load, such as torque, integrates support, rotation, transmission, fixation, sealing, corrosion protection, etc. It is a high-tech and high value-added product, widely used in lifting machinery, construction machinery and transportation. Transportation machinery, mining and metallurgical machinery, medical equipment, as well as ships, radars, wind turbines and other equipment.


ABefore the installation of the rotary table bearing, the installation surface of the main engine shall be inspected first, and the supporting parts shall have sufficient strength. The joint surface shall be machined and flat without sundries and burrs. If the required flatness cannot be achieved by machining, Special plastics with high injection strength can be used as fillers to ensure the accuracy of installation plane and to reduce vibration. The ring of the rotary table bearing has a quenching soft belt area, which is marked with "s" on the end face of the ring. When the user installs it, he should The soft belt is located in the non load area or non frequent load area (the plug hole is always located in the soft belt). When installing the bearing of the rotary table, the radial positioning shall be carried out first, the mounting bolts shall be tightened crosswise, and the rotation of the bearing shall be checked. Sufficient pre tightening force shall be provided when tightening the bolt, and the pre tightening force shall be 70% of the yield limit of bolt material. Mounting bolts shall be equipped with It is forbidden to use spring washer for tempering flat washer.


AAfter 100 hours of continuous operation of the installed and put into operation turntable bearing, the pre tightening force of the mounting bolt shall be checked comprehensively. If the torque meets the requirements, repeat the above inspection every 500 consecutive hours. After the rotary table bearing is installed, it shall be filled with proper amount of grease, and the rotary bearing shall be filled at the same time to make the grease evenly distributed. Cloth. After working for a period of time, the bearing of rotary table will inevitably lose part of lubricating grease, so it will rotate in normal operation. The disk bearing shall be supplemented with lubricating grease every 50-100 hours.
