Abstract

The invention relates to an external-fixing bearing and bearing base structure, which includes a bearing and a bearing base and is characterized in that outer sleeve of the bearing and the bearing base employs convex-concave dapped joint structure to unify into one. The external-fixing bearing and bearing base structure efficiently resolves the problem that after common bearing is burnt out, abrasion to the bearing base due to continued rotation is large and can destroy the bearing base, so that the external-fixing bearing and bearing base structure is especially adapted for rotation structure part with laboured-replacing bearing base in machinery transmission.

Description

Externally-fixed type bearing and bearing block structure

(1) technical field:

The utility model relates to the improvement of mechanical bearing technology, particularly a kind of externally-fixed type bearing and bearing block structure.

(2) background technique:

Bearing is a common components in the mechanical transmission, in use it usually and bearing support dress up one.The outer wall of its overcoat of existing bearing is the smooth cylinder or the conical surface, it and bearing support are the drive fit assembling, but adorn how closely regardless of it and bearing support, when damage of bearings " is burnt to death ", cover rotated together in the overcoat of bearing will be followed, at this moment, the inwall of bearing support is very easily wearing and tearing just, cause scrapping of bearing support.The bearing support that has is to be made as one with big parts, when bearing support is scrapped, also will change big parts, brings bigger waste.

(3) summary of the invention:

The utility model will solve when plain bearing damages exactly, easily bearing support is caused wear problems, and a kind of externally-fixed type bearing and bearing block structure are provided.

Concrete scheme of the present utility model is: improve at existing bearing and bearing block structure, it is characterized in that: bearing outside and bearing support adopt the mutual embedding structure dress of convex-concave to be one.

The utility model after damage of bearings, still can not make bearing outside rotate relative to bearing support after improving, and can not cause the wearing and tearing of bearing support, and it is just passable only to need to change bearing.The utility model is simple in structure, and is easy for installation, thoroughly solved the wear problem of bearing support.

(4) description of drawings:

Fig. 1 is the schematic representation of one of structure of the present utility model;

Fig. 2 is two a schematic representation of the utility model structure;

Fig. 3 is that the A of Fig. 2 is to partial schematic diagram.

Among the figure: 1-bearing, 2-bearing support, 3-plush copper, 4-groove, 5-bearing, 6-bearing support, 7-plush copper, 8-groove.

(5) embodiment:

Example 1: referring to Fig. 1, the utility model is made of bearing 1 and bearing support 2, particularly design has four plush coppers 3 (the rarest plush copper gets final product on the outer casing outer wall of bearing 1, a plurality of as gear shape also can), corresponding four grooves that match with plush copper 3 that have on the inwall of bearing support 2 are that one promptly constitutes one of structure of the present utility model with bearing 1 with bearing support 2 mutual setting-ins.

Example 2: referring to Fig. 2, the utility model is made of bearing 5 and bearing support 6, particularly have eight grooves 8 (nick shaped) in the edge of bearing 5 overcoats one side, design has eight plush coppers 7 that match with groove 8 on the inwall of corresponding axis bearing 6, with bearing 5 and bearing support 6 mutual setting-ins be one promptly constitute structure of the present utility model two.

Claims

1. externally-fixed type bearing and bearing block structure include bearing and bearing support, it is characterized in that: bearing outside and bearing support adopt the mutual embedding structure dress of convex-concave to be one.
