Abstract

The utility model discloses a carbon brush holder assembly, which comprises a carbon brush holder and a bearing chamber arranged on the carbon brush holder, wherein a bearing is arranged in the bearing chamber, a reinforcing rib is axially fixed on the outer side of the bearing, the reinforcing rib and the outer side of the bearing are integrally formed, and the inner shape of the bearing chamber is matched with the outer side of the bearing. Compared with the prior art, the bearing retainer is omitted, the bearing is directly injection molded in the bearing chamber by adopting the injection molding mode of the belt piece, the cost is reduced, the production process is simplified, and meanwhile, the bearing is ensured to be clamped in the bearing chamber through the inclined plane and the reinforcing ribs, so that looseness is avoided.

Description

Carbon brush holder assembly

Technical Field

The present utility model relates to a carbon brush holder assembly.

Background

The carbon brush frame component is an important component of the motor and is arranged at the tail part of the motor, the tail part of the carbon brush frame component is provided with a bearing chamber, a bearing arranged in the bearing chamber is arranged in the bearing chamber in a crimping way through a bearing retainer ring, and the mounting way of the bearing is complex in process and high in cost.

Disclosure of Invention

In view of the above, the present utility model provides a carbon brush holder assembly that effectively solves the problems noted in the background art.

The technical scheme adopted by the utility model is as follows:

the utility model provides a carbon brush holder subassembly, includes the carbon brush holder to and set up the bearing room on the carbon brush holder, the bearing room in be equipped with the bearing, the outside of bearing is fixed with the strengthening rib along the axial, the outside integrated into one piece of strengthening rib and bearing, the inside shape of bearing room and the outside assorted of bearing.

Preferably, at least three reinforcing ribs are circumferentially and uniformly distributed on the outer side of the bearing.

The plurality of reinforcing ribs can improve the torque of the bearing in the bearing chamber, ensure that the bearing chamber clamps the bearing, and avoid the reduction of looseness and concentricity caused by long-term use.

Preferably, the bearing is fixed in the bearing chamber by injection molding of the belt.

Preferably, the bearing is provided with inclined planes inclined to the middle part of the bearing at the outer sides of the two end surfaces.

The design of the inclined plane ensures that the bearing of the belt piece injection molded in the bearing chamber can not be pushed out along the axial direction, and simultaneously ensures the concentricity of the bearing and the carbon brush frame.

Compared with the prior art, the bearing retainer is omitted, the bearing is directly injection molded in the bearing chamber by adopting the injection molding mode of the belt piece, the cost is reduced, the production process is simplified, and meanwhile, the bearing is ensured to be clamped in the bearing chamber through the inclined plane and the reinforcing ribs, so that looseness is avoided.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings by means of specific examples.

As shown in fig. 1-5, a carbon brush holder assembly comprises a carbon brush holder 1 and a bearing chamber 2 arranged on the carbon brush holder 1, wherein a bearing 3 is arranged in the bearing chamber 2, a reinforcing rib 4 is axially fixed on the outer side of the bearing 3, the reinforcing rib 4 and the outer side of the bearing 3 are integrally formed, and the inner shape of the bearing chamber 2 is matched with the outer side of the bearing 3.

At least three reinforcing ribs 4 are circumferentially and uniformly distributed on the outer side of the bearing 3.

The bearing 3 is fixed in the bearing chamber 2 by a belt piece injection molding mode.

The bearing 3 is provided with inclined planes 5 inclined towards the middle part of the bearing 3 at the outer sides of the two end surfaces.

According to the utility model, when the carbon brush holder 1 is subjected to injection molding, the bearing 3 is directly subjected to injection molding in the bearing chamber 2, and the bearing is not required to be assembled, so that the process is simplified, the cost is reduced, and the production efficiency is improved.

The utility model is very convenient and quick in the process of dismounting the carbon brush 7, and can improve the replacement efficiency of the carbon brush 7.

Finally, it should be noted that the above list is only specific embodiments of the present utility model. Obviously, the utility model is not limited to the above embodiments, but many variations are possible. All modifications directly derived or suggested to one skilled in the art from the present disclosure should be considered as being within the scope of the present utility model.
