Abstract

The utility model discloses a kind of open-close type pivoting support, include the half-turn of two double subdivisions, and the split surface of one of them half-turn is provided with grafting groove, the split surface of another half-turn is provided with and constitutes, with described grafting groove, the grafting projection that grafting coordinates, each half-turn all includes inner ring, outer ring, steel ball and retainer, steel ball is installed on retainer, and correspondence is between inner ring and outer ring, described retainer is fixed on inner ring, owing to pivoting support provided by the utility model is to be made up of the half-turn of two double subdivisions, two half-turns can freely separate and close the most in the course of the work, can rotate normally after Guan Bi, it is thus possible to the use demand met under special operation condition.

Description

A kind of open-close type pivoting support

Technical field

This utility model relates to technical field of bearings, is specifically related to a kind of open-close type pivoting support.

Background technology

Pivoting support is a kind of big profile shaft that can simultaneously bear bigger axial load, radial load and tilting moment Holding, it is widely used in ship equipment, engineering machinery, light industry and machinery, metallurgical machinery, medical machinery, industrial robot, wind-powered electricity generation row The fields such as industry.But owing to existing pivoting support is all the integrative-structure of whole circle, therefore half-and-half split when some need its work Special operation condition under cannot use.

Summary of the invention

For the deficiencies in the prior art, this utility model provides a kind of open-close type pivoting support, and it is cutd open for double by two Point half-turn constitute, two half-turns can freely separate and close the most in the course of the work, meet the use demand of special operation condition.

For achieving the above object, this utility model provides a kind of open-close type pivoting support, includes two double subdivisions Half-turn, and the split surface of one of them half-turn is provided with grafting groove, and the split surface of another half-turn is provided with to be inserted with described Connecing groove and constitute the grafting projection that grafting coordinates, each half-turn all includes inner ring, outer ring, steel ball and retainer, and steel ball is installed On retainer, and correspondence is between inner ring and outer ring, and described retainer is fixed on inner ring, and axial one end of inner ring sets Have the inner ring barb extended radially outwardly, axial one end of outer ring be correspondingly provided with insertion described inner ring barb in and with described inner ring It is protruding that barb forms the outer ring connected and fixed, and the axial other end of outer ring is provided with the outer ring barb extended radially inwardly, inner ring Axially the other end is correspondingly provided with and inserts in the barb of described outer ring and form the inner ring projection connected and fixed with described outer ring barb.

The beneficial effects of the utility model are: use said structure, owing to pivoting support provided by the utility model is Being made up of the half-turn of two double subdivisions, two half-turns can freely separate and close the most in the course of the work, permissible after Guan Bi Normal rotation.Meanwhile, at Guan Bi, use grafting groove and the such male-female engagement of grafting projection, pivoting support essence can be guided Really Guan Bi, allows and does not misplaces between raceway, it is ensured that pivoting support normally rotates.Further, since inner ring and axial the one of outer ring End is to be fixed by inner ring barb and outer ring male cooperation, and the axial other end of inner ring and outer ring is by outer ring barb and inner ring Male cooperation is fixed, and therefore can form labyrinth sealing between inner ring and outer ring, effectively prevents external dust from entering and affecting Steel ball normal rotation.

This utility model can be further arranged on described inner ring offer the groove loaded for retainer, described holding By welding or threaded engagement is fixed between frame with groove.Retainer is fixed on the groove of inner ring, two can be prevented effectively from Half-turn separately time steel ball drop.

Detailed description of the invention

Give a kind of open-close type pivoting support as shown in Figure 1, 2, 3, include the half-turn 1 of two double subdivisions, and its In the split surface of a half-turn 1 be provided with grafting groove 2, the split surface of another half-turn 1 is provided with and described grafting groove 2 structure Becoming the grafting projection 3 that grafting coordinates, each half-turn 1 all includes inner ring 11, outer ring 12, steel ball 13 and retainer 14, steel ball 13 It is installed on retainer 14, and correspondence is between inner ring 11 and outer ring 12, described inner ring 11 offers for retainer 14 The groove 111 loaded, by welding or threaded engagement is fixed between described retainer 14 and groove 111.Axial the one of inner ring 11 End is provided with the inner ring barb 112 extended radially outwardly, and axial one end of outer ring 12 is correspondingly provided with in the described inner ring barb 112 of insertion And forming, with described inner ring barb 112, the outer ring projection 121 connected and fixed, the axial other end of outer ring 12 is provided with and radially-inwardly prolongs The outer ring barb 122 stretched, the axial other end of inner ring 11 is correspondingly provided with in insertion described outer ring barb 122 and falls with described outer ring Hook 122 forms the inner ring projection 113 connected and fixed.Use said structure, owing to pivoting support provided by the utility model is It is made up of the half-turn 1 of two double subdivisions, can freely separate and close again by two half-turns 1 the most in the course of the work, can after Guan Bi Rotate with normal.Meanwhile, use grafting groove 2 and the such male-female engagement of grafting projection 3 at Guan Bi, revolution can be guided Hold accurately Guan Bi, allow and do not misplace between raceway, it is ensured that pivoting support normally rotates.

Claims

1. an open-close type pivoting support, it is characterised in that: include the half-turn of two double subdivisions, and one of them half-turn Split surface is provided with grafting groove, and the split surface of another half-turn is provided with and constitutes, with described grafting groove, the grafting that grafting coordinates Projection, each half-turn all includes inner ring, outer ring, steel ball and retainer, and steel ball is installed on retainer, and correspondence is positioned at inner ring With between outer ring, described retainer is fixed on inner ring, axial one end of inner ring is provided with the inner ring barb extended radially outwardly, Axial one end of outer ring is correspondingly provided with inserts in described inner ring barb and convex with the outer ring that the formation of described inner ring barb connects and fixes Rising, the axial other end of outer ring is provided with the outer ring barb extended radially inwardly, and the axial other end of inner ring is correspondingly provided with insertion institute State in the barb of outer ring and form the inner ring projection connected and fixed with described outer ring barb.
