Technical requirements for the assembly of rolling bearings: 1. (3) From the rear end of the box body, install the rear bearing housing subassembly into the box body and tighten the screws. Two bearing pads are inserted on the bearing pads, and reasonable adjustments are made with gaskets at the joints. It is mainly assembled by pressing and hammering. 3. Two-way fixing at one end This fixing method is to fix the bearing at one fulcrum in two directions, while the bearing at the other fulcrum can move axially to adapt to the fixing method of the thermally elongated bearing of the shaft. (3) The direction of the maximum radial runout of the inner ring of the front and rear bearings is opposite to the direction of deviation of the centerline of the spindle taper hole. The solution: one is to punch the hard material with a sample before drilling, and the second is to use a short drill to increase the drill. 1. Assembly method of separable bearing cone Roller bearings are typical of separable bearings. (1) Remove burrs from the sleeve and bearing housing holes, and apply lubricant to the bearing housing holes after cleaning. The structure of the spindle component 2. 6. The assembled bearings should operate flexibly with low noise, and the temperature rise during working should not exceed the allowable value. At the same time, pay attention to control the clearance between the shaft and the shaft within the tolerance range. 4. (6) Carry out a comprehensive inspection of the assembly situation to prevent omissions and misassembly. The rigidity of the drill when making holes. Due to the different hardness of the casing and the sleeve material, it is easy to deflect the drill bit to the soft material side. The inner hole should be trimmed and inspected by reaming or scraping to ensure that there is between miniature deep groove ball bearings suppliers the journal and the sleeve Good clearance fit. Keep clean during assembly to prevent foreign objects from entering the bearing. The end faces with marking codes on the rolling bearings should be installed in the visible direction so that they can be checked during replacement. (6) Based on the main shaft, the inner hole of the scraping bearing is equipped to make the contact accuracy qualified, and ensure that the coaxiality of the front and rear bearing holes meets the requirements
