Abstract
The invention relates to an axial positioning structure. The axial positioning structure comprises an annular slot which is arranged on an outer stretching end of a shaft, two half bushing brushes which are embedded in the annular slot, a sleeve ring which is sleeved outside the two half shaft bushings and an elastic retainer ring, wherein a retainer ring slot which is arranged outside and a limiting step which is arranged inside are arranged on outer circumferential surfaces of the two half shaft bushings; the elastic retainer ring is blocked in a retainer ring slot; and the sleeve ring is arranged between the elastic retainer ring and the limiting step. The axial positioning device solves the technical problem that the current axial positioning structure is difficult to mount and dismount, and a locking gasket is easily damaged in a dismounting process, has a small integral axial dimension, a large bearing axial force, a broad application range, high reliability, and is convenient to mount, change and maintain. The axial positioning device is very convenient to mount, change and maintain as the base structure is simple.
Description
Technical field
The present invention relates to a kind of axial positioning structure, particularly relate to a kind of rotary rotor axial positioning structure.
Background technique
Existing rotor has locking nut, circlip, cotter pin and spindle nose bolt structure etc. with axial positioning structure.Locking nut size is larger, and screw thread can not bear very large axial force, also will prevent from rotating in a circumferential direction; Circlip and cotter pin all can not be born large axial force; A general spindle nose screw and the lock washer of adopting of spindle nose bolt structure carries out axially locating to rotor, when this structure mounts and dismounts more difficult and lock washer mounting or dismounting, easily damages.
Summary of the invention
The object of the invention is to propose a kind of rotary rotor axial positioning structure.It has solved some shortcomings of existing axial direction positioning device.
Technical solution of the present invention is:
A kind of rotor axial positioning device, its special way is: comprise the overhanging end that is arranged on axle 5 circular groove 8, embed two halfliners (1,2) in circular groove 8, be enclosed within two halfliners (1,2) the outer collar 3, circlip 4, described two halfliners (1,2) external peripheral surface is provided with the circlip groove 10 that is positioned at outside and the limited step 9 that is positioned at inner side; Described circlip 4 is stuck in circlip groove 10; The described collar 3 is between circlip 4 and limited step 9.
Between above-mentioned two halfliners (1,2) and ring slot outside end face and rotor 6 outside end faces, be little Spielpassung or transition fit.
Between above-mentioned two halfliners (1,2) and ring slot outside end face and rotor 6 outside end faces, be little Spielpassung, between end face, be provided with and adjust pad 7 outside described two halfliners (1,2) and rotor.
Between the above-mentioned collar 3 and two halfliners (1,2), it is little Spielpassung.
Above-mentioned two halfliners (1,2) are stainless steel material or nonmetallic material.
Above-mentioned two bearing shells are processed in the following way: first two bearing shells are carried out to entirety and be machined to size, then symmetry is separated into two halves, and stamp respectively identical mark.
Advantage of the present invention is:
1, overall axial dimension is little, can bear very larger axial force.
2, axial direction positioning device applied range.As long as all applying this structure in the place that needs axially locating; The material of halfliner, the collar and the pad of axial direction positioning device of the present invention can be in numerous stainless steel metal materials or nonmetallic material preferred, the direct selection standard series of circlip for shaft.
3, reliability is high.The present invention can bear very large axial force with two halfliners, and the collar plays the effect of the centrifugal force when fixing two halfliners and bearing its High Rotation Speed.The collar is not subject to axial force in theory, only needs a common circlip for shaft to its axially locating.In practical application, all obtain good effect.
4, be convenient to install and repair and replacement.The present invention is because basic structure is simple, and installation and repair and replacement are all very convenient.
Brief description of the drawings
Fig. 1 is the structural representation of rotor axial positioning device of the present invention;
Wherein: 1-halfliner, 2-halfliner, the 3-collar, 4-circlip for shaft, 5-axle, 6-rotor, 7-pad, 8-circular groove, 9-limited step, 10-circlip groove.
Embodiment
The structure of rotor axial positioning device of the present invention is shown in Fig. 1, comprises halfliner 1, halfliner 2, the collar 3, circlip for shaft 4, axle 5, rotor 6, pad 7; Two halfliners 1,2 are embedded in the circular groove on axle 5 and bear axial force; Pad 7 is for adjusting the gap of bearing shell and rotor end-face; The collar 3 is enclosed within two halfliner 1,2 outsides to fix bearing shell and to bear the issuable radial force of bearing shell; Circlip for shaft 4 is contained in the groove of opening on two halfliners the collar 3 is carried out to axial restraint.
Two halfliners 1 and 2 adopt stainless steel material or nonmetallic material, are separated into two halves after processing together each size again, stamp respectively identical mark and deposit in pairs.The axial dimension of the groove that guarantee circlip for shaft 4 will pack into is consistent.
The principle of the invention: rotor axial positioning device of the present invention utilizes two halfliners to carry out the axial force of bear rotor, fix two halfliners to fix bearing shell and to bear the issuable radial force of bearing shell with the collar, the collar is carried out to axially locating with circlip for shaft; Between halfliner and rotor, adopt transition fit or little Spielpassung; The axial force of rotor can be delivered on the pillow block of axle head by two halfliners.And the centrifugal force that axle when rotation produces two halfliners is born by the collar.The collar is not subject to axial force, it is carried out to axially locating with standard circlip for shaft.
