滚动轴承的轴向紧固(国外英文资料) The shaft of the rolling bearing is fastened Tighten the inner circle of the bearing ???? When the inner circle of the bearing is mounted on the shaft, it is usually placed on the side of the shaft. The other side USES nuts, stop washer and spring coil etc. The size of the contact part of the shaft shoulder and the shaft to the contact part of the bearing ring, can be determined according to the dimensions of the various bearings listed in the basic dimension of the bearing. ???? (1) in the bearing is high speed, under high axial load cases, nut contact with bearing ring end face perpendicular to the axis of rotation axis, or tighten nut will damage the bearing the correct installation position, the rotation of the lower bearing precision and service life, especially with the bearing inner hole and shaft for loose fit more strict control. In order to prevent nuts from being loose in rotation, proper precautions should be taken to prevent nuts from being loose by using grooved nut and stop washer. Place the inner tooth of the washer into the keyway of the shaft, and then bend any external tooth into the nut. ???? (2) the shaft is fastened by elastic ring. In the case of the axial load, low bearing speed, and the difficulty of the shaft neck, the profile is the elastic ring of the rectangle. This kind of fastening method installs convenience, the area is small, cost is low. ???? (3) the end thrust gasket fastening?? For journal on screwing with difficulty, bearing high speed, large axial load, washer on the shaft end with two screw fastening, with a lock washer with or locking wire. ???? (4) tighten the set of the set. To the spherical bearing of the spherical bearing with the double column of low speed and stable radial load and small axial load, it can be mounted on the bare shaft with a conical shape. Tighten the use of nut and stop washer, tighten the lock of the nut lock and tighten the bearing. (5) the fastness of the taper hole bearing. The t
