Abstract
The utility model discloses a novel bearing positioning check ring. An annular groove is formed in a shaft of a roller; two semi-circular check rings are put inside the groove, so that the axial force is born, and the shaft is axially positioned; a fixing ring sleeve is sleeved on the shaft to fix the two semi-circular check rings, and the axial force is not born; the ring sleeve is positioned through an elastic check ring. The thicknesses of the semi-circular check rings can be designed according to the born axial force. The novel bearing positioning check ring has the beneficial effect that a roller shaft can be reliably positioned in the axial direction under the condition that the roller shaft is subjected to a large axial force.
Description
Technical field
The utility model belongs to machanical fastener, is specifically related to the bearing positioning retainer ring on textile manufacturing machine roll mandrel.
Background technique
In textile manufacturing machine, generally adopting circlip for shaft or adopting round nut to add lock washer locates bearing on axle.While adopting circlip for shaft, existence can not be born the shortcoming of larger axial force; While adopting round nut to add lock washer, the processing more complicated of axle, not only wants machining screw, also needs to process locking groove, and the structure space requiring is larger.
Summary of the invention
The purpose of this utility model is to solve roll shaft in the situation that bearing very larger axial force, and roll shaft is in axial reliable location.
The technical solution that the utility model proposes is: on the axle of roller, drive a circular groove, two semicircle back-up rings are put into groove, in order to bear axial force, and make axle in axially locating.Put Fixing shrink ring, in order to fix two semicircle back-up rings, do not bear axial force; With circlip, Fixing shrink ring is positioned.The thickness of semicircle back-up ring can be according to the size of born axial force and difference.
The beneficial effects of the utility model are: in the situation that roll shaft bears very larger axial force, roll shaft can be located in the axial direction reliably.
Accompanying drawing explanation
Fig. 1: the structural representation that is the application of the utility model bearing positioning retainer ring.
In figure: 1. roll 2. oil sealing 3. bearing cap 4. paper washer 5. bearing support 6. bearing 7. semicircle back-up ring 8. Fixing shrink ring 9. circlips
Embodiment
As shown in the figure, bearing (6) is arranged in bearing support (5) hole, bearing cap (3) is in order to the outer ring of rigid bearing (6), paper washer (4) is as adjusting pad, oil sealing (2) is done sealing, drives a circular groove on the axle of roll (1), and two semicircle back-up rings (7) are put into groove, put Fixing shrink ring (8), Fixing shrink ring (8) is located by circlip (9).Two semicircle back-up rings (7) bear axial force, and Fixing shrink ring (8) drops out circular groove to prevent two semicircle back-up rings (7).
Claims (2)
1. novel bearing positioning retainer ring, it is characterized in that: on the axle of roller, drive a circular groove, two semicircle back-up rings (7) are put into groove, put to fix the Fixing shrink ring (8) of two semicircle back-up rings (7), then use circlip (9) to locate Fixing shrink ring (8).
2. novel bearing positioning retainer ring according to claim 1, is characterized in that: the thickness of semicircle back-up ring (7) can be according to the size of born axial force and difference.
