Different mechanical bearing clearance adjustment method

Machinery and equipment, use of bearing type operation will also have no, according to the requirement of the machinery used to select the use of the bearing, the bearing in the different mechanical conditions how to clearance adjustment? 崋 bearing in the network according to the understanding of different types of bearing knowledge, to share the different mechanical bearing clearance adjustment method, hope to be of help. 1, the car front wheel hub of the tapered roller bearing inner ring clearance adjustment method: generally USES coronary nut, washer with wing with a split pin, lock washer with adjusted fixed ( Use the back nut to lock shaft nut is not desirable, because the bearing clearance will be adjusted for screw meshing clearance change and change) , make the bearing with a small amount of interference. 2, transportation, mine car for swimming round is similar to the automobile wheel hub, the impact of the difference between driving is larger, the speed is low, so the need for tighter some adjustments. Clearance adjustment methods: generally USES coronary nut, washer with wing with a split pin, lock washer with adjusted fixed ( Use the back nut to lock shaft nut is not desirable, because the bearing clearance will be adjusted for screw meshing clearance change and change) , make the bearing with a small amount of interference. 3 impact load, king pin, steering gear bearing in the bearing clearance is harmful to the clearance adjustment method: for the thrust bearing, steering knuckle fork and shaft structure height tolerance of jaw, with washer s adjustment during assembly. And therefore should be equipped with a variety of different thickness of the gasket. 4, lathe spindle of cylindrical roller bearings, thrust ball bearing the inside of the bearing clearance is smaller, the higher rigidity and working accuracy. Clearance adjustment methods: working temperature rise with the decrease of the clearance. So want to travel when installation gap with the best temperature relationship. With a nut M of cylindrical roller bearing inner ring fastened on the conical journal, thereby reducing the radial clearance; At the same time, the thrust bearing with nut N group to adjust without clearance. Configuration between the two thrust bearing of spring can make because of work pressure and the bearing requirement of unloading of interference. 5, the main work under static load and under the vibration of cylindrical roller bearing clearance adjustment method: man finishing S adjustment, must contain a small amount of interference. 6, low speed, bearing large crane heavy steel rope support clearance adjustment method: using nut M to the adjustment of tapered roller bearings, with the necessary interference. 7, static state and smaller rotary tiller can withstand strong vibration in the movement of the bearing clearance adjustment methods: there can be no clearance, or roller will be the impact of raceway. So before the installation of bearing radial clearance clearance should be less than 0 group. Can be made of the value of the original radial clearance, bearing cone fitted the taper and the pressure of the screw thread pitch calculate, need to how much pressure screw screw turn to reach bearing preloaded. No clearance fit the required 8, bidirectional thrust ball bearing clearance adjustment method: use to adjust the nut M, after bearing adjustment should have a fairly advance, interference, unload a list of goals in the work can still along the groove movement in a reliable way. 9, thrust ball bearing clearance adjustment methods: usually also use a fixed cover gasket S clearance adjustment. Thrust ball bearings are best on the vertical shaft, because the ball cage can relatively concentric with ring.
