Abstract

The invention discloses a maintenance-free middle bracket assembly without a bearing seat and a bracket oil seal, which mainly comprises a rubber pad and the like, wherein a U-shaped annular groove is designed on the inner ring of the rubber pad, a bearing is directly embedded and assembled in the U-shaped annular groove, an installation shaft is arranged in the bearing, the left side and the right side of the outer ring of the bearing are blocked by two side edges of the U-shaped annular groove, the outermost side of the two side edges of the U-shaped annular groove protrudes outwards to form an upward-raised rubber lip, a dust cover is arranged on the outer side of the rubber lip in a matched mode and forms a labyrinth structure to play a waterproof role, one side of the dust. The bearing is a maintenance-free bearing. The maintenance-free bearing is directly arranged in the rubber pad, so that the structure is simplified, the reliability is improved, a plurality of assembling procedures are reduced, the production period is shortened, and the cost is reduced; the labyrinth waterproof structure is formed after the bearing is matched with the dust cover, the efficient waterproof effect is achieved, and the maintenance-free purpose of the middle bracket assembly is achieved by using the maintenance-free bearing.

Description

Non-maintaining intermediate support assembly without bearing block and support oil seal

Technical Field

The invention relates to the field of transmission shaft assemblies, in particular to a maintenance-free middle bracket assembly without a bearing seat and a bracket oil seal.

Background

The general intermediate support assembly mainly comprises the following components: lower bracket 1, former rubber pad 2, support oil blanket 3, bearing 4, snap ring 5, bearing frame 6. Bearing 4 installs in bearing frame 6, is fixed a position by snap ring 5 about bearing 4, and two 5 outsides of snap ring are equipped with support oil blanket 3 and are used for sealed, then become a whole through vulcanizing bonding between bearing frame 6 and former rubber pad 2, and former rubber pad 2 dress is inside lower bracket 1. This structure has the following drawbacks: the structure is complicated, and assembly process is many, and part quantity is many, and the cost is higher, and the support bearing is the maintainable type, need regularly to refuel and maintain.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a maintenance-free intermediate bracket assembly without a bearing seat and a bracket oil seal.

The purpose of the invention is achieved by the following technical scheme: the maintenance-free middle bracket assembly without the bearing seat and the bracket oil seal mainly comprises a lower bracket, a bearing, a rubber pad, a dust cover, rubber lips and a U-shaped annular groove, wherein the U-shaped annular groove is designed on the inner ring of the rubber pad, the bearing is directly embedded and assembled in the U-shaped annular groove, an installation shaft is arranged in the bearing, the left side and the right side of the outer ring of the bearing are blocked by two sides of the U-shaped annular groove, the outermost sides of the two sides of the U-shaped annular groove protrude outwards to form the rubber lips which are tilted upwards, the dust cover is installed outside the rubber lips in a matched mode, a labyrinth structure is formed to play a waterproof role, and.

The bearing is a maintenance-free bearing.

The invention has the beneficial effects that: according to the invention, the maintenance-free bearing is directly arranged in the rubber pad, parts such as the bearing seat, the snap ring, the bracket oil seal and the like are eliminated, more than five parts are reduced, the structure is greatly simplified, the possibility of failure is greatly reduced, the reliability is improved, a plurality of assembling procedures are reduced, the production period is shortened, and the cost is reduced; form labyrinth waterproof construction through matching with the dust cover, play high-efficient waterproof effect, through using non-maintaining bearing, reach the non-maintaining purpose of intermediate strut assembly, reduced the maintenance cost.

Description of reference numerals: the device comprises a lower bracket 1, an original rubber pad 2, a support oil seal 3, a bearing 4, a snap ring 5, a bearing seat 6, a rubber pad 7, a dust cover 8, a rubber lip 9, a U-shaped annular groove 10 and a shaft 11.

Detailed Description

The invention will be described in detail below with reference to the following drawings:

example (b): as shown in the attached drawings, the maintenance-free intermediate support assembly without the bearing seat and the support oil seal mainly comprises a lower support 1, a bearing 4, a rubber pad 7, a dust cover 8, a rubber lip 9, a U-shaped annular groove 10 and a shaft 11, wherein the U-shaped annular groove 10 is designed on the inner ring of the rubber pad 7, the bearing 4 is directly embedded and assembled in the U-shaped annular groove 10, and the bearing 4 is a maintenance-free bearing, so that the maintenance-free purpose of the intermediate support assembly is achieved. Installation axle 11 in the bearing 4, the bearing 4 outer lane left and right sides is blocked by two sides of U-shaped ring groove 10, and two outside evaginations of two sides in U-shaped ring groove 10 form one up perk's rubber lip 9, and the cooperation installation dust cover 8 in the rubber lip 9 outside forms labyrinth structure in order to play water-proof effects, and axle 11 is withstood to dust cover 8 one side, and rubber pad 7 dress is inside lower bracket 1.

It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
