Deep groove ball bearing ring internal positioning method

1. Deep groove ball bearing inner ring located in deep groove ball bearings are installed on the bearing inner ring, generally by the shoulder in a fixed bearing position, while the other side with a nut and lock washer with archives circle, such as fixed or spring. Shoulder and axial fixed parts in contact with the bearing inner ring the size of the part, as shown in table bearing size all kinds of bearing installation dimensions. （ 1) Nut positioning in the deep groove ball bearing with high speed and under high axial load cases, nut contact with the bearing inner ring end face should be perpendicular to the rotation of the shaft centerline. Or even tighten nut will damage the installation position of the bearing and the bearing of the normal working state, reduce the bearing rotation precision and service life. Especially with the bearing inner hole and shaft for the loose fit, more must be strictly controlled. In order to prevent the nut loose in spinning process, need to take the appropriate measures to prevent loose technology. Using a nut and lock washer with positioning, will be key lock washer with tooth in shaft keyway, then each tooth on the outer ring of a bent into the incision of nut. （ 2) Spring archives circle positioning in the deep groove ball bearings under axial load is not big, the speed is not high, the shaft is shorter and the axis neck processed into threads are difficult circumstances, can be used for rectangular elastic gear ring cross section. This kind of method of loading and unloading is very convenient, location of small, simple. （ 3) Thrust washer positioning in the deep groove ball bearing journal, shorter axis neck processed into thread with difficulty, bearing high speed, under the condition of axial load is bigger, the gasket can be used to locate, use washer on the shaft end face with more than two fixing screw, with a lock washer with or wire screw die, to prevent loosening. （ 4) Tight sleeve positioning deep groove ball bearing rotating speed is not high, under the less steady radial load and axial load of spherical roller bearing, can decide on the optical axis with conical tight set of installation. Set to paraphrase nut and lock washer with positioning. Using the nut lock tight sleeve friction bearing positioning. （ 5) Within the inner hole of taper bearing positioning hole has a taper bearings on the taper shaft installation, need to make the top tight shaft and bearing axial load detector, so when installation should pay attention to the direction of the inner hole taper. Such as bearing in the shaft end and in the end allows processed into thread, can directly use nut positioning. If the bearing is not installed on the shaft end, and shaft are not allowed to processed into thread. In this case, the available two merger, thread ring card to the axis of the slots with a nut positioning bearing. （ 6) Special position in some special circumstances, deep groove ball bearing shaft shoulder and fillet size not listed in the catalog installation dimensions, transition gasket can be used as the axial bearing. 2. Positioning deep groove ball bearing outer ring of bearing outer ring installed in the shell hole, hole on the inside of the outer shell usually have accounted for the position of the shoulder fixed bearing, on the other side with end cover, thread ring and hole with elastic circle of positioning. （ 1) Orientation of end cover end cover is used for all types of centripetal bearing and angular contact bearings, bearing in high speed, large axial load under the condition of use. End cover with screw positioning pressure bearing outer ring, the end cover can also be made of labyrinth seal device. （ 2) Thread ring positioning deep groove ball bearing high rotational speed, axial load is bigger, not suitable for the use of end cover positioning, available thread ring locate centripetal bearing and thrust bearing, this can be used to adjust the axial clearance of bearing. （ 3) Elastic gear ring positioning the positioning method of axial position is small, easy installation and removal, simple manufacturing, apply to smaller under axial load. Between bearing and spring and an adjusting ring, easy to adjust the axial location. （ 4) Deep groove ball bearing outer ring with a stopper on the slot of deep groove ball bearings, available positioning snap ring. When the shell hole as a result of the limitation of conditions can't stop processing gear shoulder, or component must outline size, selection of this type.
