Abstract
The utility model relates to a draper-type positioning retainer of a slewing bearing rolling ball, belonging to slewing bearings. The draper-type positioning retainer is characterized by consisting of a draper body, rolling ball seat holes, upper circular arc bosses and lower circular arc bosses, wherein the section of the draper body is a flat rectangular long draper; the left end part of the draper body is provided with a dovetail joint; the right end part of the draper body is provided with a dovetail groove; the dovetail joint and the dovetail groove are embedded correspondingly to form a full circle which serves as a retainer body of each rolling ball; the upper circular arc bosses and lower circular arc bosses, which are integrated with the draper body, are uniformly arranged on the upper parts and the lower parts of the front surface and the rear surface of the draper body at intervals from left to right with the central line at the length direction of the draper body as the reference; ball surface holes are formed on the draper body and each group of upper circular arc bosses and the lower circular arc bosses on the front surface and the rear surface of the draper body, thus the rolling ball seat holes are formed; and rolling balls are respectively installed in each rolling ball seat hole, thus the performances of the slewing bearing are improved, the service life is long, and the use field is wide.
Description
Technical field
The utility model belongs to pivoting support, especially relates to a kind of location retainer of pivoting support ball.
Background technique
Existing 4 contact single-row ball type slewing bearings; Its rolling element (ball) is isolated with spacing block usually; But long-term use of existing spacing block is prone to produce wearing and tearing, and the circular gap between each ball is increased, and spacing block can send collision noise when pivoting support rotated; Even occurrence of tilting is stopped up the phenomenon of raceway; Especially require vertical installations, high rotating speed, low startup when square, low noise and long lifetime when pivoting support, existing spacing block just can not satisfy these requirements, and the using scope of pivoting support is restricted.
Summary of the invention
The purpose of the utility model is to propose pivoting support ball belt location retainer; Not only quick and easy for installation; Highly versatile; And the performances such as setting angle, rotating speed, starting torque, noise of pivoting support are increased substantially, and prolong the working life of pivoting support, expand the use field of pivoting support.
The purpose of the utility model is that realization is like this: a kind of pivoting support ball belt location retainer; It is characterized in that this pivoting support ball belt location retainer mainly by belt body, ball base hole (pocket hole) and last arc cam, arc cam is formed down, this belt body is that the cross section is square long being with of prolate, and the seamed edge of belt body upper and lower sides is arc transition; Left part at belt body has dovetail joint; And correspondence is offered dovetail groove in the right part of belt body, and the corresponding interlocking with dovetail groove of this dovetail joint and synthetic full circle are as the maintenance support body of each ball; And the length of this belt body can be according to the girth of pivoting support raceway center circle and intercepting; Highly versatile, the upper and lower of the front and rear surfaces of belt body with the length direction of belt body (about) center line be as the criterion, be uniformly distributed with the compartment of terrain from left to right and have the last arc cam and following arc cam of processing one with belt body respectively; Be this each on arc cam and following arc cam be as the criterion with the center line of belt body facade (short transverse) and be symmetrically distributed in groups; Go up simultaneously under arc cam, the front and back arc cam before and after this each and all be as the criterion again and make symmetry and distribute, and the outer side surface of this each upper and lower arc cam is arc surface, also be arc transition between this each upper and lower arc cam and the belt body surface with belt body thickness; On arc cam and following arc cam on each group on belt body and the front and rear surfaces thereof with (being thickness) in the tape thickness cross section of belt body vertically the joint of center line and horizontal center line be that sphere hole is offered at the center; Become ball base hole (pocket hole), this each ball base hole (sphere hole) on the belt body from left to right (tape body length direction) respectively organize in front and back accordingly on the upper and lower arc cam evenly and distribute, the somewhat larger in diameter in this ball base hole is in the diameter of ball; This retainer can adopt nylon to process; The ball that in each ball base hole, is slidingly installed respectively makes each ball circumferential location and evenly isolating in the raceway of pivoting support, and each ball is smooth and easy rotation in the ball base hole; Can not collide and make a noise because of the high speed rotating of pivoting support; Can make the retainer radial location again, can when the pivoting support high speed rotating radial-play not take place and with pivoting support Internal and external cycle friction, noise is low; Go up simultaneously arc cam and strengthened the intensity in ball base hole with following arc cam, the ball base hole is indeformable when making belt body crooked.
The pivoting support ball belt location retainer that the utility model proposed; Rational in infrastructure; Safe and reliable, highly versatile, and the performances such as setting angle, rotating speed, starting torque and noise of pivoting support are increased substantially; Prolong the working life of pivoting support, expanded the use field of pivoting support.
Combine accompanying drawing and embodiment that the pivoting support ball belt location retainer that the utility model proposes is described further at present.
