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 and use axial positioning structure.
Background technique
Existing rotor has locking nut, circlip, cotter pin and spindle nose bolt structure etc. with axial positioning structure.The locking nut size is bigger, and screw thread can not bear very big axial force, also will prevent to rotate in a circumferential direction; Circlip and cotter pin all can not be born big axial force; A general spindle nose screw and the lock washer of adopting of spindle nose bolt structure comes rotor is carried out axially locating, and these structure installation and removal relatively damage when difficulty and lock washer mounting or dismounting easily.
Summary of the invention
The objective of the invention is to propose a kind of rotary rotor and use 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 circular groove 8 that is arranged on axle 5 overhanging end, embed two halfliners (1,2) in the circular groove 8, be enclosed within two halfliners (1,2) the outer collar 3, circlip 4, said two halfliners (1,2) external peripheral surface is provided with the circlip groove 10 that is positioned at the outside and is positioned at inboard limited step 9; Said circlip 4 is stuck in the circlip groove 10; The said 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 is little Spielpassung or transition fit.
Between above-mentioned two halfliners (1,2) and ring slot outside end face and rotor 6 outside end faces is little Spielpassung, is provided with adjustment pad 7 between said two halfliners (1,2) and the rotor outside end face.
Between the above-mentioned collar 3 and two halfliners (1,2) is little Spielpassung.
Above-mentioned two halfliners (1,2) are stainless steel material or nonmetallic material.
Above-mentioned two bearing shells adopt following mode to process: earlier two bearing shells are carried out integral body and be machined to size, symmetry is separated into two halves again, and stamps identical mark respectively.
Advantage of the present invention is:
1, whole axial dimension is little, can bear very larger axial force.
2, axial direction positioning device applied range.All can use this structure so long as need the place of axially locating; The material of the halfliner of axial direction positioning device of the present invention, the collar and pad can be in numerous stainless steel metal materials or nonmetallic material preferred, the direct selection standard series of circlip for shaft gets final product.
3, reliability is high.The present invention can bear very big axial force with two halfliners, the action of centrifugal force the when collar plays fixing two halfliners and bears its high speed rotating.The collar does not receive axial force in theory, only needs a common circlip for shaft that its axially locating is got final product.All obtained good effect in the practical application.
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.
Description of 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 seen 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 the axle 5 and bear axial force; Pad 7 is used to adjust the gap of bearing shell and rotor end-face; The collar 3 is enclosed within two halfliner 1,2 outsides with fixing bearing shell and 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 axial restraint.
Two halfliners 1 and 2 adopt stainless steel material or nonmetallic material, are separated into two halves again after processing each size together, stamp identical mark respectively and deposit in pairs.The axial dimension that guarantees the groove that circlip for shaft 4 will be packed into is consistent.
The principle of the invention: rotor axial positioning device of the present invention utilizes two halfliners to come the axial force of bear rotor; Fix two halfliners with fixing bearing shell and bear the issuable radial force of bearing shell with the collar, the collar is carried out axially locating with circlip for shaft; Adopt transition fit or little Spielpassung between halfliner and the rotor; The axial force of rotor can be delivered on the pillow block of axle head through two halfliners.And when rotation axle born by the collar the centrifugal force that two halfliners produce.The collar does not receive axial force, with the standard circlip for shaft it is carried out axially locating.
