Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] Such as Figure 1-2 As shown, the electric brush of a refrigeration motor according to the present invention includes a brush chamber 1 with an unclosed top surface, and a plurality of brush body 1 2 and brush body 2 3 are arranged in the brush chamber 1. The body one 2 and the brush body two 3 are arranged at intervals, the bottom end of the brush body one 2 is fixedly arranged on the inner bottom surface of the brush cavity body 1, the bottom end of the brush body two 3 is fixedly connected with a spring 4, and the other end of the spring 4 is fixedly arranged On the inner bottom surface of the brush chamber 1.
[0018] As a preferred mode of the present invention, the top surfaces of the first brush body 2 and the second brush body 3 are provided with wear-resistant strips. This can enhance the wear resistance of the brush body.
[0019] As a preferred for...

The invention relates to the technical field of the refrigerating industry, in particular to an electric brush of a refrigerating motor. The electric brush of the refrigerating motor comprises a brush cavity with the top end face unclosed. A plurality of brush bodies I and a plurality of brush bodies II are arranged in the brush cavity, the brush bodies I and the brush bodies II are arranged at intervals, the bottom ends of the brush bodies I are fixedly arranged on the bottom face in the brush cavity, the bottom ends of the brush bodies II are fixedly connected with springs, and the other ends of the springs are fixedly arranged on the bottom face in the brush cavity. When the electric brush is used, the brush bodies II which move elastically upwards and downwards and the fixed brush bodies I cooperate with one another and then rub with a rotor, the abrasion resistance of the electric brush is greatly enhanced, therefore, normal use of the motor can be guaranteed and normal operation of refrigerating equipment can be guaranteed. The electric brush of the refrigerating motor has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
technical field [0001] The invention relates to the technical field of the refrigeration industry, in particular to a brush of a refrigeration motor. Background technique [0002] The role in the motor is to change the direction of the current and divide it into a DC motor and an AC motor. The DC motor is used to change the conductive coil of the rotor, thereby changing the rotor magnetic pole. Thereby changing the motion of the motor. The carbon brush is used on the commutator or slip ring of the motor. As a sliding contact body that leads and imports current, it has good electrical conductivity, thermal conductivity and lubricating performance, and has a certain mechanical strength and the instinct of commutation sparks. [0003] When the motor works normally, the electric brushes will generate mechanical friction with each other. The existing electric brushes are not wear-resistant and are easily damaged, which will affect the normal use of the motor, and then affect the...
