Abstract
The utility model discloses a kind of brush motor rear end cap denoising structure, including rear end cap and armature spindle, the middle inside of the rear end cap is provided with spherical surface pit, and spherical surface oiliness bearing is provided in the spherical surface pit；The middle inside of the rear end cap is additionally provided with the noise control deep gouge for avoiding rotor shaft end, and the noise control deep gouge is located at the lower section of spherical surface pit, and the noise control deep gouge is diameter that is round and having a diameter larger than rotor shaft end.The utility model brush motor rear end cap denoising structure, it avoids the end of armature spindle by the way that noise control deep gouge is arranged, to make armature spindle not contacted with rear end cap in rotary course, it can effectively avoid the problem that existing motor motor temperature caused by due to armature spindle is contacted when rotated with rear end cap increases and noise increases.
Description
Technical field
The utility model is related to technical field of motors, more particularly to a kind of rear end cover structure of brush motor.
Background technology
Currently, going up spherical surface pit in the middle part of the rear end cap of brush motor, spherical surface oiliness bearing, motor are provided in spherical surface pit
Armature spindle be through in spherical surface oiliness bearing.Rotor axis of electric has after being installed on rear end cap partially passes through spherical surface oil-containing axis
It holds, and the rotor shaft end beyond spherical surface oiliness bearing is easy to contact with the surface of spherical surface pit during rotation turns, in turn
Motor temperature is caused to increase the problem of increasing with noise.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of brush motor rear end cap denoising structure, it is existing to solve
Brush motor armature spindle is contacted with spherical surface pit surface, and motor temperature is caused to increase the technical issues of increasing with noise.
The utility model brush motor rear end cap denoising structure, including rear end cap and armature spindle, the inside of the rear end cap
Middle part is provided with spherical surface pit, and spherical surface oiliness bearing is provided in the spherical surface pit；
The middle inside of the rear end cap is additionally provided with circular groove, and the circular groove is located at the top of spherical surface pit,
And it is provided in circular groove with the felt circle coordinated in the middle part of spherical surface oiliness bearing and is coordinated with spherical surface oiliness bearing top
Bearing presss from both sides, and being additionally provided on the rear end cap prevents bearing from pressing from both sides the retaining flange exited from annular groove；
The middle inside of the rear end cap is additionally provided with the noise control deep gouge for avoiding rotor shaft end, the noise control deep gouge
Positioned at the lower section of spherical surface pit, the noise control deep gouge is diameter that is round and having a diameter larger than rotor shaft end.
The beneficial effects of the utility model：
The utility model brush motor rear end cap denoising structure avoids the end of armature spindle by the way that noise control deep gouge is arranged
Portion can effectively avoid existing motor from being rotated because of armature spindle to make armature spindle not contacted with rear end cap in rotary course
When contacted with rear end cap and caused by motor temperature increase and noise increase the problem of.

As shown, the present embodiment brush motor rear end cap denoising structure, including rear end cap 1 and armature spindle 2, the rear end
The middle inside of lid is provided with spherical surface pit 3, and spherical surface oiliness bearing 4 is provided in the spherical surface pit.
The middle inside of the rear end cap is additionally provided with circular groove 5, and the circular groove is located at the top of spherical surface pit,
And it is provided in circular groove with the felt circle 6 coordinated in the middle part of spherical surface oiliness bearing and is coordinated with spherical surface oiliness bearing top
Bearing folder 7, being additionally provided on the rear end cap prevents bearing from pressing from both sides the retaining flange 8 exited from annular groove.
The middle inside of the rear end cap is additionally provided with the noise control deep gouge 9 for avoiding rotor shaft end, and the noise control is heavy
Slot is located at the lower section of spherical surface pit, and the noise control deep gouge is diameter that is round and having a diameter larger than rotor shaft end.
The present embodiment brush motor rear end cap denoising structure avoids the end of armature spindle by the way that noise control deep gouge is arranged,
To make armature spindle not contacted with rear end cap in rotary course, can effectively avoid existing motor because armature spindle when rotated with
Rear end cap contact and caused by motor temperature increase and noise increase the problem of.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
