Description
Technical Field
The utility model relates to a mechanical connection technique, concretely relates to carborundum axle sleeve is used to axle.
Background
In the part in the motion, the pivot is installed in the shaft hole, because long-term use can cause the wearing and tearing between pivot and shaft hole, generally set up the axle sleeve and play the guard action to the pivot in the pivot, but pivot and axle sleeve also are constantly rubbing in supporting use, and at present, the axle sleeve mostly is a hollow cylinder cover, and this cylinder cover and rotation axis connection back, pivoted flexibility is relatively poor on the one hand, and the axle sleeve is worn and torn with the axle sleeve friction for a long time to another side's axle.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an axle is with carborundum axle sleeve to expect to solve in the background art the problem.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides an axle is with carborundum axle sleeve, includes outer axle sleeve, is provided with interior axle sleeve in outer axle sleeve, outer axle sleeve sets up the clearance with interior axle sleeve to be provided with the upper bearing on this clearance upper portion, be provided with down the bearing in this clearance lower part, outer axle sleeve and the outer loop and the outer axle sleeve inner wall welded connection of interior axle sleeve, interior axle sleeve inside wall top is provided with the rubber ring.
Furthermore, outer axle sleeve and interior axle sleeve all weld the setting on the base, are provided with the cambered surface arch at the base center, and this cambered surface arch is located interior axle sleeve inboard.
Furthermore, screw holes are formed in two sides of the base.
Furthermore, the top end of the inner shaft sleeve is integrally provided with an annular bending edge, and the annular bending edge covers a gap between the outer shaft sleeve and the inner shaft sleeve.
Further, the inner sleeve is made of silicon carbide material.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, through being provided with inside and outside two-layer and be provided with the bearing in the two-layer clearance, the pivot sets up in interior axle sleeve, can increase bearing pivoted flexibility through the bearing, and is provided with the cambered surface arch in order to reduce the friction between pivot end and the base including in the axle sleeve to the flexibility has further been improved, interior axle sleeve is made by silicon carbide material and has increased its wearability and life.
