Bearing inner and outer circle fixed - bearing this knowledge

Bearing the axial axial positioning and fastening contains axial fixation. In order to avoid the bearing on the shaft and the bearing hole move, 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, depending on the limit requirements of the support and the type of bearing is used. Image for the company to film, do not steal figure positioning and fixed inside and outside the circle of the rolling element bearing a lot of methods, the following for several 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) With screw shaft end ring fastening, can be used under the high speed under large axial force, should be screw locking measures; c) With a round nut and lock washer with fastening, mainly used in high speed, large 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 assembly; f) With bearing end cover fastening, used in high speed, large axial force under all kinds of centripetal, thrust and radial 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 fastening. e) The locking groove of the outer race elastic ring f) By bearing end cover implementation of outer ring positioning g) Hole with elastic ring to achieve outer ring positioning h) Thread ring positioning methods fixed axial fastening including axial positioning and axial fixation. In order to prevent the bearing on the shaft and the bearing hole, bearing inner ring must tighten on the shaft; The outer ring must tighten the bearing hole ( Or set of glasses) 。 Bearing inner and outer ring needs to be a two-way or one-way axial fastening, swimming or axial, depending on the limit requirements of the bearing and the bearing type. 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, must use the internal force of the opposite direction, the outer ring with one-way axial fastening. If using swimming shall fraction of bearing support, just ring inside the bidirectional axial fastening on the shaft, the outer ring relative to the swimming hole axial freedom; 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 usually 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 also should be selected according to the standard, so that can ensure positioning strength have ease of installation.
