Description

Thin-wall waterproof bearing

Technical Field

The utility model relates to a bearing technical field especially relates to a thin wall waterproof bearing.

Background

A bearing is a mechanical element that limits relative motion to a desired range of motion and reduces friction between moving parts. The design of the bearings can provide free linear movement or free rotation of the moving part about a fixed axis, and can also prevent movement by controlling the vector of the normal force acting on the moving part. The existing thin-wall bearing can only carry out load of radial force, and when the thin-wall bearing receives axial force, the bearing is easily damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that the axial force load can not be carried out that exists among the prior art, and the thin wall waterproof bearing who provides.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a thin wall waterproof bearing, includes the outer lantern ring, the equal fixedly connected with sealing washer in both ends about the outer lantern ring inner wall, the inner circle butt of sealing washer has the interior lantern ring, first arc wall has been seted up on the outer wall of interior lantern ring, the second arc wall has been seted up on the inner wall of outer lantern ring, first arc wall with the second arc wall all is ring shape, the second arc wall with it has a plurality of balls to fill between the first arc wall, the spacing groove has all been seted up on the upper and lower both ends inner wall of outer lantern ring, the spacing groove is ring shape, equal a plurality of stoppers of fixedly connected with on the upper and lower both ends outer wall of interior lantern ring, stopper slidable sets up in the spacing groove.

Preferably, the sealing ring comprises a connecting layer, a wear-resistant layer is fixedly connected to one side of the connecting layer, and the wear-resistant layer is abutted to the inner sleeve ring.

Preferably, the ball is a stainless steel ball.

Preferably, the surface of the outer sleeve is coated with a rust-proof layer.

Preferably, the thickness ratio of the outer collar to the inner collar is 3: 1.

The utility model provides a pair of thin wall waterproof bearing, beneficial effect lies in: through the design that adopts spacing groove and stopper, play the effect of support, play the effect of being connected between interior lantern ring and the outer lantern ring to make the bearing can carry out the load of axial force, avoided the condition that the bearing damaged to appear, simultaneously through the design that adopts sealed pad, play waterproof effect to the bearing, prevent the entering of moisture.
