Abstract

The utility model relates to a modified bearing room cooperation structure. The existing bearing chamber is a structure wrapped by a whole circle, a bearing generally needs to be matched in a sliding mode, the bearing can be placed into the bearing chamber and needs a little holding force, the requirements on the precision of a die and injection molding parameters are high in the matching process of the structure and the bearing, the situation that the noise is generated due to the fact that the bearing is too loose or tight and the matching is improper can often occur. The utility model discloses top-down forms a plurality of radial spaced ring channels on the inner wall of bearing room, the bearing room in insert the bearing cooperation and connect, still set up rather than a communicating semicircle orifice on one side of the bearing room. The utility model discloses improve the cooperation of bearing and bearing room, reached the sliding fit effect easily, be unlikely to the pine or tension.

Description

Improved bearing chamber matching structure

Technical Field

The utility model relates to a modified bearing room cooperation structure.

Background

The existing bearing chamber is a structure wrapped by a whole circle, a bearing generally needs to be matched in a sliding mode, the bearing can be placed into the bearing chamber and needs a little holding force, the requirements on the precision of a die and injection molding parameters are high in the matching process of the structure and the bearing, the situation that the noise is generated due to the fact that the bearing is too loose or tight and the matching is improper can often occur.

SUMMERY OF THE UTILITY MODEL

The defect to prior art exists, the utility model provides a modified bearing room cooperation structure has reduced the area of contact that the bearing put into the in-process, reaches transition complex effect more easily.

Therefore, the utility model adopts the following technical scheme: an improved bearing chamber matching structure is characterized in that a plurality of spaced clearance grooves are formed on the inner wall of a bearing chamber in the radial direction or the axial direction, and a bearing is inserted into the bearing chamber to be matched and connected.

Preferably, a plurality of convex blocks are circumferentially distributed on the inner wall of the bearing chamber at intervals, axial clearance grooves are formed between adjacent convex blocks, and the inner end surfaces of the convex blocks are arc-shaped surfaces.

Preferably, the width of the clearance groove is smaller than that of the bump.

Preferably, six projections are formed on the inner wall of the bearing chamber at regular intervals.

Preferably, a plurality of radial spaced annular grooves are formed on the inner wall of the bearing chamber from top to bottom.

The utility model discloses radial or axial on the bearing room sets up and keeps away the dead slot, makes clearance and keeps away empty complex structure, improves the cooperation of bearing and bearing room, reaches the sliding fit effect easily, is unlikely to the pine or tension.

Drawings

Fig. 1 is a schematic structural view of the axial clearance groove of the present invention.

Fig. 2 is a schematic cross-sectional view of the present invention.

Fig. 3 is a schematic view of the three-dimensional structure of the radial clearance groove of the present invention.

Fig. 4 is a schematic view of the cross-sectional structure of the radial clearance groove of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the bearing chamber structure of the rear cover includes a cover body 4 and an end cover 3, a bearing chamber 6 is disposed in the center of the end cover, a plurality of bumps 1 are circumferentially distributed on the inner wall of the bearing chamber at intervals, a spacing groove 5 is formed between adjacent bumps, and the inner end surface of each bump is an arc surface.

The width of the groove is smaller than that of the bump. Six lugs are formed on the inner wall of the bearing chamber at uniform intervals. A plurality of convex ribs are formed between the outer wall of the bearing chamber and the cover body. Two convex ribs which are a group are respectively formed on the outer wall of the bearing chamber corresponding to each spacing groove. The outer side of each group of convex ribs is provided with a mounting hole 2. The cover body forms hollow parts 7 in the front, back, left and right directions respectively.

Referring to fig. 3 and 4, a bearing housing structure of the front bracket 8 is shown, in which a plurality of radially spaced annular grooves 9 are formed on an inner wall of the bearing housing from top to bottom.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Claims

1. An improved bearing chamber matching structure is characterized in that a plurality of radial spaced annular grooves are formed in the inner wall of a bearing chamber from top to bottom, a bearing is inserted into the bearing chamber to be matched and connected, and a semicircular hole communicated with the bearing chamber is formed in one side of the bearing chamber.
