Fixed bearing inner and outer ring

Bearing the axial axial positioning and fastening contains axial fixation. In order to prevent the bearing on the shaft and the bearing hole, bearing inner ring is necessary to tighten on the shaft, the outer ring is necessary to tighten the bearing hole. Two-way bearing inner and outer ring demand remains a one-way axial fastening, swimming or axial, depends on the support of limit, the request and the type of bearing is used. Image for the company to film, do not steal figure roller bearing inner and outer circle there are a number of ways for positioning and fixed, the following for several kinds of commonly used methods. a) With shaft with retaining ring embedded in the shaft inside the groove, it is mainly used for axial force is not big and the speed is not high; b) Use screw shaft end ring fastening, can be used to accept large axial force under high speed, screw should be locking measures; c) With a round nut and lock washer with fastening, mainly used in high speed, accept the condition of the larger axial force; d) With a taper sleeve positioning, check washer and nut fastening, used in optical axis, bearing inner ring for the taper hole. a) Shoulder and spring collar location b) Shoulder with the shaft collar location c) Shoulder, round nut and lock washer with positioning d) With taper sleeve positioning e) With embedded housing groove inside the hole with elastic ring, it is mainly used for axial force is not big and decrease the size of bearing installation; f) With bearing end cover fastening, used in high speed, accept large axial force centripetal, thrust and centripetal thrust bearing; g) With shaft with elastic ring embedded stopper of bearing outer ring groove clamp, used when the shell inconvenience when setting convex shoulder; h) Use thread ring clamp for bearing high speed, large axial force, and is not suitable for bearing end cover the status of the fastening. e) The locking groove of the outer race elastic ring f) Complete the outer orientation with bearing end cover g) Hole complete outer ring with elastic ring positioning h) Thread ring positioning common fixed way to tighten including axial axial positioning and axial fixation. In order to avoid the bearing on the shaft and the bearing hole move, bearing inner ring must tighten on the shaft; Outer ring must tighten the bearing hole ( Or set of glasses) 。 Inner and outer ring of bearing demand bidirectional or one-way axial fastening, swimming or axial, depends on the bearing limit requests and the type of bearing is used. Image for the company to film, do not steal figure in a double limit bearing ( The fixed bearing) , the inner ring on the shaft, bearing outer ring in the bearing hole shall be two-way axial fastening. In one-way limit bearing, it is necessary in the opposite direction of the force inner and outer ring with one-way axial fastening. If use swimming shall fraction of bearing support, just ring inside the bidirectional axial fastening on the shaft, the outer ring associated with a hole at the axial winding; When using internal and external ring can be divided into swimming the centripetal bearing support, the internal and external ring must be two-way axial fastening on the shaft and hole, inner and outer ring of bearing relative axial winding. Bearing axial positioning is ordinary shoulder positioning to inner ring, outer ring bearing hole ( Or set of cups) Retaining shoulder. In order to ensure that the shaft shoulder and shoulder the positioning of the role, should make the shaft shoulder and shoulder and bearing inner and outer ring end face against. The height of the shoulder and shoulder selection should be according to the specification, so that can ensure positioning strength have ease of installation.
