Abstract

The utility model discloses a vibration-proof arc top armature structure, namely, a rubber insulating pad and a U-shaped bakelite pad are additionally arranged at the top of a brush body, a connecting through hole is arranged on the rubber insulating pad, a lead connected with an external insulating protective layer is connected with a brush joint, and the U-shaped bakelite pad can draw in a lead-out wire harness of the brush joint, so that the clamping position of a brush holder compression spring of the brush joint is accurate, and the compression spring is prevented from being pressed askew and sliding; the rubber insulating pad can play the effect that the elasticity was kept away and is shaken, promotes the operating stability of brush and the life of brush, prevents that the brush from connecting because the too big emergence accident of vibration is cheap or throw off. The utility model discloses can effectively promote the operating stability and the efficiency of motor.

Description

Vibration-proof arc top armature structure
Technical Field
The utility model relates to a keep away circular arc top armature structure that shakes for motor field.
Background
The electric brush of the motor is a conductive sliding contact body, also called a carbon brush, for transmitting energy or signals between a fixed part and a rotating part of a rotating machine such as a motor or a generator. The top of the traditional electric brush is in an inclined plane state, so that the phenomenon of pressure distortion or deflection can occur when a spring brush holder is pressed on the top of the electric brush, the conditions of poor contact of uneven pressure of the electric brush, clamping of a shell and the like are caused, and the electric brush burst accident can occur under severe conditions. If the brush in the direct current motor has problems, sparks are enlarged, and the normal use of the motor is affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming prior art's not enough, provide a keep away circular arc top armature structure that shakes, it can prevent effectively that the brush that causes because of pressure spring pressure is askew, the landing presses uneven phenomenon partially, the brush pressurized, prevents the emergence of phenomenons such as card shell, burst.
One technical scheme for achieving the above purpose is as follows: a vibration-proof arc top armature structure comprises an electric brush body connected with an electric brush joint and a vibration-proof connecting part arranged at the top of the electric brush body;
the vibration-avoiding connecting part comprises a rubber insulating pad and a U-shaped bakelite pad, the rubber insulating pad is arranged at the top of the brush body, the U-shaped bakelite pad is arranged on the rubber insulating pad, the cross section of the side surface of the U-shaped bakelite pad is U-shaped, two connecting through holes are symmetrically formed in the rubber insulating pad and the U-shaped bakelite pad, two insulating sleeves are inserted into the connecting through holes, and a copper wire connector is arranged in the insulating sleeve and connected with the brush body;
the electric brush connector is provided with a pressure spring, the bottom of the electric brush connector is a protruding connecting part, and the electric brush connector is connected with the electric brush body through a copper wire.
Furthermore, the brush joint is divided into two connecting wires, and each connecting wire is coated with an insulating layer.
Further, the thickness of the rubber insulating pad is 3-5 cm.
The utility model discloses a keep away circular arc top armature structure that shakes, has add rubber insulation pad and U type bakelite pad at brush body top promptly, has seted up the connecting hole on it, is connected with the wire and the brush joint of external insulation inoxidizing coating by the wire of being connected with, U type bakelite pad can draw in the extraction pencil of brush joint in, makes the brush holder pressure spring screens of brush joint accurate, prevents that the pressure spring from pressing askew, the landing; the rubber insulating pad can play the effect that the elasticity was kept away and is shaken, promotes the operating stability of brush and the life of brush, prevents that the brush from connecting because the too big emergence accident of vibration is cheap or throw off. The utility model discloses can effectively promote the operating stability and the efficiency of motor.

fig. 3 is a schematic diagram of an electric brush joint of the vibration-proof arc top armature structure of the present invention.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments:
referring to fig. 1 to 3, the anti-vibration arc top armature structure of the present invention includes an electric brush body 1 connected to an electric brush joint 3, and an anti-vibration connecting portion disposed at the top of the electric brush body.
Please refer to fig. 1 and fig. 2. The vibration-proof connecting part comprises a rubber insulating pad 21 and a U-shaped bakelite pad 22. The rubber insulating pad is arranged at the top of the electric brush body 1, the thickness of the rubber insulating pad is 3-5cm, the rubber insulating pad can generate elastic deformation when being extruded, certain displacement allowance can be provided for the butt joint of the electric brush joint 3 and the electric brush body 1, and the effect of elastic vibration avoidance is achieved. The U-shaped bakelite pad 22 is arranged on the rubber insulation pad 21 and is used for strengthening and fixing the butt joint part of the electric brush joint 3 and the electric brush body 1, and the section shape of the side surface of the U-shaped bakelite pad is U-shaped, so that the outgoing line of the electric brush joint 3 can be bundled, the clamping position of a pressure spring of the electric brush joint 3 is accurate, and the pressure spring is prevented from being pressed askew and sliding off. Two connecting through holes are symmetrically formed in the rubber insulating pad 21 and the U-shaped bakelite pad 22, two insulating sleeves 23 are inserted into the connecting through holes, and copper wire joints connected with the electric brush body 1 are arranged in the insulating sleeves.
Referring to fig. 3, the brush joint 3 is provided with a compression spring 31, the bottom of the brush joint 3 is a protruding connection portion 33, and the brush joint 3 is connected to the copper wire joint at the top of the brush body 1 through a copper wire lead 32. When brush joint 3 is connected with brush body 1, pressure spring 31 pushes down and makes brush joint 3 and brush body 1 be close to, and the two passes through lead-out wire and articulate, and connecting portion 33 joint is difficult for droing in U type inslot this moment.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
