Slewing bearings is a kind of large bearing which can bear comprehensive load.However, this part has been used for a long time. Due to the manufacturing quality problems such as the material pores or interlayers, the hardness of the hardened layer and uneven depth of the raceway, etc., or some external reasons, the raceway peeling layer or the tooth ring broken tooth, the equipment cannot work normally.How to fix it?Let me explain to you today!
For raceway stripping, the first to make a correct judgment.The appearance of peeling layer, generally in the outside is not easy to see.Generally, the raceway has stripping layer: when the main engine is carrying the rotation, the raceway has a "cro-crook" sound, and the rotating speed is not uniform or a certain azimuth speed slows down significantly with slight vibration;Too high temperature rise or too high current;Key slots of rotary motors and hydraulic couplers or coupling etc. are jammed.
