Abstract
The utility model relates to a shaft sleeve provided with a wear-resisting oil pit. The shaft sleeve provided with the wear-resisting oil pit comprises a shaft sleeve body (1) and concave oil pits (2) which are formed on the inner wall of the shaft sleeve body, wherein a bulge (3) which is formed on the inner wall of the shaft sleeve body is arranged on a connecting position between the oil pits, the surface of the bulge is of an arc shape, and a silicon carbide wear-resisting layer is arranged below the bulge (3). After adopting the structure, frictional force of the inner wall of the shaft sleeve body is not acted on a sharp surface and is uniformly distributed on the arc surface, and the silicon carbide wear-resisting layer which is arranged below the bulge can effectively bear the frictional force when used. Simultaneously, the oil pits arranged on the inner wall of the shaft sleeve body also can not be rubbed down because of friction, thereby guaranteeing lubrication effect, and prolongs service life of a shaft sleeve.
Description
Technical field
The utility model relates to a kind of axle sleeve that is provided with wear-resisting oil hole.
Background technique
In the parts at the volley, axle is installed in axis hole, because long-term use can cause the wearing and tearing between axle and axis hole, in order to improve the working life of axle, at all outer surfaces axle sleeve is set.For axle sleeve can be used for a long time; Generally also a mouth that is marked with that can in body, inject lubricant oil is being set on the sleeve body; Be provided with the oil hole that can supply lubricant oil to store at the sleeve body inwall accordingly; Adjacent oil hole forms sharp-pointed projection at the sleeve body inwall in the existing sleeve body, and this design use for a long time can cause the oil hole to make the lubrication effect variation because of sharp-pointed partly friction.
Summary of the invention
The purpose of the utility model is exactly the problem that can make the lubrication effect variation for the use for a long time of existing axle sleeve.
The technological scheme that the utility model adopts is: a kind of axle sleeve that is provided with wear-resisting oil hole; Comprise sleeve body and form recessed oil hole at the sleeve body inwall; Connection part between the described oil hole forms projection at the sleeve body inwall; The surface of said projection is an arc surface, and said projection below is provided with the silicon carbide wearing layer.
The beneficial effect that the utility model adopts is: after adopting this structure; The frictional force of sleeve body inwall is not acting on the sharp-pointed face but is being evenly distributed on the arc surface, and the silicon carbide wearing layer that the projection below is provided with can effectively bear the frictional force when using; Simultaneously the oil of sleeve body inwall hole can be because of friction not be polished yet, thereby has guaranteed lubrication effect, has prolonged the working life of axle sleeve.
Description of drawings
Fig. 1 is the utility model schematic representation.
Embodiment
As shown in Figure 1; A kind of axle sleeve that is provided with wear-resisting oil hole comprises sleeve body 1 and forms recessed oil hole 2 at the sleeve body inwall that the connection part between the described oil hole forms projection 3 at the sleeve body inwall; The surface of said projection is an arc surface, and described projection 3 belows are provided with silicon carbide wearing layer 4.After adopting this structure, the frictional force of sleeve body inwall is not acting on the sharp-pointed face but is being evenly distributed on the arc surface, and the silicon carbide wearing layer that the projection below is provided with can effectively bear the frictional force when using; Simultaneously the oil of sleeve body inwall hole can be because of friction not be polished yet, thereby has guaranteed lubrication effect, has prolonged the working life of axle sleeve.
Claims (1)
1. one kind is provided with the axle sleeve that wear-resisting oil is cheated; Comprise sleeve body (1) and form recessed oil hole (2) at the sleeve body inwall; Connection part between the described oil hole forms projection (3) at the sleeve body inwall; The surface that it is characterized in that said projection (3) is an arc surface, and described projection (3) below is provided with silicon carbide wearing layer (4).
