Abstract

The utility model relates to a novel rubber coated bearing which comprises an outer ring, wherein an antiskid groove is formed on the outer peripheral surface of the outer ring, and the novel rubber coated bearing is characterized in that the antiskid groove is an 8-shaped groove formed by two ring-shaped grooves along the circumference, wherein the two ring-shaped grooves approach each other from the end with maximum spacing interval and are intersected at the other end. The novel rubber coated bearing has the benefits that as the two ring-shaped grooves of the antiskid groove approach each other from the end with maximum spacing interval and are intersected mutually, the novel rubber coated bearing can not only reliably prevent relative sliding or detachment between the bearing and a rubber product in the axial direction of the bearing, but also reliably prevent the relative sliding or the detachment between the bearing and the rubber product in the circumferential direction and other angles and directions of the bearing. Furthermore, the antiskid groove in the shape can not only be realized on a numerical control lathe, but also be processed on a special instrument lathe for ordinary bearings after simple transformation, thereby realizing the batch processing of the antiskid grooves, improving the working efficiency and reducing the production cost.

Description

Novel encapsulate bearing

Technical field

The utility model relates to a kind of novel encapsulate bearing, being mainly used in some in use need be in the occasion of rubber tire such as the outer circumferential face pressure injection of bearing outer ring or adhesive rubber, polyurethane glue and PU glue or other glue goods, as elevator castor, elevator upper saw pulley, elevator door with change gear, hanging wheel bearing, furniture pulley etc.

Background technique

The encapsulate bearing mainly is according to the purposes of bearing in some occasion, at bearing outside diameter surface pressure injection or rubber tire or other glue goods such as adhesive rubber, polyurethane glue and PU glue, so be referred to as the encapsulate bearing.

Because encapsulate bearing matrix one bearing outside diameter surface is a smooth cylndrical surface, the surperficial encapsulate rear bearing in use variation of temperature and environmental conditions causes bearing and easy slide relative of glue goods or slippage.People are at encapsulate bearing matrix external diameter surface processing anti-slip tank for this reason, consider the characteristics (requiring to produce in batches easily, improve automation) that bearing is made, on the market at present the anti-slip tank of processing mainly be the straight flute that processes single groove, double flute even multiple-grooved along the circumference of bearing outer ring outer circumferential face, that the cross section shape of groove is equipped with is square, semicircle etc.Such anti-slip tank can only be in the axial slide relative or the slippage that effectively prevents between bearing and the encapsulate of bearing, and it is not high in circumferencial direction and its reliability of other angle direction of bearing, the encapsulate bearing is bearing and easy slide relative of glue goods or slippage in use, lost encapsulate bearing proper function, the reliability of encapsulate bearing does not satisfy usage requirement.

Summary of the invention

The purpose of this utility model provides a kind of novel encapsulate bearing, can only be with the anti-slip tank that the solution prior art exists in the axial slide relative or the slippage that effectively prevents between bearing and the encapsulate of bearing, and it is not high in circumferencial direction and its reliability of other angle direction of bearing, the encapsulate bearing is bearing and easy slide relative of glue goods or slippage in use, lost encapsulate bearing proper function, the reliability of encapsulate bearing does not satisfy the problem of usage requirement.

The technical solution of the utility model is: comprise the outer ring, outer circumferential face in this outer ring is provided with anti-slip tank, it is characterized in that, described anti-slip tank is by two toroidal cavities along circumference, asymptotic mutually from an end of maximum spacing, and intersect at the other end and constitute 8 font grooves.

The beneficial effects of the utility model are: because the asymptotic and mutual intersection of spacing of two annular grooves of anti-slip tank, so not only in the slide relative or the slippage that axially can prevent bearing and glue goods reliably of bearing, and the slide relative or the slippage that can both prevent bearing and glue goods reliably at circumferencial direction and other angle direction of bearing.And the anti-slip tank of this shape not only can be realized on numerically controlled lathe, but also can on through the simple plain bearing meter specially lathe of transforming, process, can realize the batch process of this anti-slip tank, improve working efficiency, reduce cost of production.

Embodiment

Referring to Fig. 1 and Fig. 2, the utility model comprises outer ring 1, outer circumferential face in this outer ring 1 is provided with anti-slip tank, it is characterized in that, described anti-slip tank is by two toroidal cavities 2 along circumference, asymptotic mutually from an end of maximum spacing, and intersect at the other end (referring to the intersection point among Fig. 2 3) and constitute 8 font grooves." 8 font " is to be that the plane is deployed in two annular grooves 2 in the figure on the plane of this intersection point 3 with intersection point 3.

The shape of cross section of anti-slip tank is same as the prior art, can be the arbitrary shape of processing arbitrarily.

Claims

1. a novel encapsulate bearing comprises the outer ring, and the outer circumferential face in this outer ring is provided with anti-slip tank, it is characterized in that, described anti-slip tank is by two toroidal cavities along circumference, and is asymptotic mutually from an end of maximum spacing, and intersects at the other end and constitute 8 font grooves.
