Description
Technical Field
The utility model relates to the technical field of electric machines, in particular to mounting structure of motor carbon brush.
Background
In the traditional motor design, the carbon brush is generally positioned between two wire packages of the stator winding, so that the design is convenient for the assembly of the motor, and the carbon brush is installed in the final procedure after the motor is assembled. However, this design causes the brush box structure of the carbon brush to protrude, and is easily interfered with the body of the corresponding device (e.g., household electrical appliance, etc.), and the corresponding device needs to be increased in size to be normally installed. Therefore, there is a need to provide a new installation structure of carbon brush for motor, so that the structure of the motor is more compact and the volume of the corresponding equipment is smaller.
It is seen that improvements and enhancements to the prior art are needed.
SUMMERY OF THE UTILITY MODEL
In view of the foregoing disadvantages of the prior art, an object of the present invention is to provide a mounting structure of a carbon brush of an electric machine, which aims to solve the technical problem of large occupied space of the carbon brush of the electric machine in the prior art.
In order to achieve the purpose, the utility model adopts the following technical proposal:
a mounting structure of a motor carbon brush comprises a support, wherein the support comprises four connected supporting rods, a circular through hole is formed in the center of the support, and a first connecting hole is formed in the end part of each supporting rod; a connecting rod is arranged on any two adjacent supporting rods respectively, and at least two connecting rods are provided with a carbon brush respectively; each carbon brush is located between the stator winding and the commutator of the motor.
Furthermore, in the installation structure of the carbon brush of the motor, the included angle between any two support rods is 90 degrees.
Furthermore, in the mounting structure of the carbon brush of the motor, each connecting rod is provided with two second through holes respectively.
Furthermore, in the mounting structure of the carbon brush of the motor, each connecting rod is provided with one carbon brush.
Furthermore, in the mounting structure of the carbon brush of the motor, each second connecting hole is a threaded hole.
Furthermore, in the mounting structure of the carbon brush of the motor, each connecting rod is an arc-shaped rod.
Has the advantages that: the utility model provides a mounting structure of motor carbon brush compares prior art, the utility model provides an in the mounting structure of motor carbon brush through setting up the support, set up the connecting rod on the support, install the carbon brush on the connecting rod, and the carbon brush is located between the stator winding and the commutator of motor, inside each carbon brush is located the motor on the whole for the installation of carbon brush is compacter, has avoided carbon brush mounted position among the prior art to be outstanding on motor housing, thereby makes the overall dimension of motor reduce.

Fig. 2 is a perspective view of a bracket in the installation structure of the carbon brush of the motor provided by the utility model.
Fig. 3 is an application schematic diagram of the mounting structure of the carbon brush of the motor provided by the utility model.
Detailed Description
The utility model provides a mounting structure of motor carbon brush, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following combination embodiment the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 3, the present invention provides an installation structure of a carbon brush of a motor.
A mounting structure of a motor carbon brush comprises a support, wherein the support comprises four connected support rods 1, connecting rods 2 are respectively arranged on any two adjacent support rods, and at least two connecting rods are respectively provided with a carbon brush 4; a circular through hole 101 is formed in the center of the support, and a first connecting hole 102 is formed in the end of each supporting rod; each carbon brush is located between the stator winding 8 of the machine and the commutator (not shown) and the carbon brushes are not in contact with the stator winding. Furthermore, it can be seen from the figure that each carbon brush is located on the side of the connecting rod facing the rotor. The circle arranged in the support is used for a motor main shaft to penetrate through, the commutator is arranged on the motor main shaft and is the prior art, and the structure of the commutator is not specifically shown in the attached drawings.
Preferably, the included angle between any two support rods 1 is 90 °. This setting makes the support be central symmetry structure on the whole, and the processing of being convenient for, and every bracing piece atress of support is balanced.
Preferably, each connecting rod 2 is provided with two second through holes 102, so as to be conveniently connected with the corresponding carbon brushes.
Preferably, each connecting rod 2 is provided with one carbon brush 4, that is, four carbon brushes are provided, so that the current flowing through each carbon brush is relatively reduced, which is beneficial to prolonging the service life of the carbon brush.
Preferably, each of the second connection holes 102 is a threaded hole, so as to facilitate bolt connection during actual assembly.
Preferably, every connecting rod 2 is the arc pole, has improved the mechanical strength of connecting rod.
According to the above analysis, compare prior art, the utility model provides an among the mounting structure of motor carbon brush, through setting up the support, set up the connecting rod on the support, install the carbon brush on the connecting rod, and the carbon brush is located between the stator winding and the commutator of motor, inside each carbon brush is located the motor on the whole for the installation of carbon brush is compacter, has avoided among the prior art carbon brush mounted position outstanding on motor housing, thereby makes the overall dimension of motor reduce.
It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
