Problems solved by technology

[0003] During use, although the shell of the explosion-proof motor is not sealed, the flame-proof motor mainly uses the flame-proof shell to separate the electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture, which is harmful to the motor. The airtightness of the main body has certain requirements, so that it cannot dissipate heat through holes like conventional motors
[0004] Therefore, at present, the explosion-proof motor mainly relies on the heat dissipation fins on the shell for heat dissipation during use. Although the material of the heat dissipation fins can also be used to complete effective heat dissipation, however, during the long-term continuous use of the explosion-proof motor, its surface The position of the heat dissipation fins often accumulates a large amount of dust, which seriously affects the heat dissipation capacity of the motor body, and seriously affects the service life of the explosion-proof motor if it is not cleaned in time manually. Therefore, we propose an explosion-proof stepping motor

Abstract

The invention discloses an explosion-proof stepping motor, and the motor comprises a motor main body and heat dissipation fins; a cleaning part is arranged on the outer side of the motor main body, the cleaning part is in matched contact with the heat dissipation fins, a linkage part is arranged at the end part of the motor main body, and the linkage part is in butt joint with an output shaft of the motor main body; and an output shaft of the motor main body is used for driving the cleaning part to move on the radiating fins to clean dust. The explosion-proof stepping motor is different from the prior art, and the cleaning part and the linkage part are combined for use, so in the continuous use process, the motor main body can automatically clean the dust accumulated at the positions of the heat dissipation fins on the motor main body, so the continuous and effective heat dissipation use of the motor main body is effectively ensured, and the service life of the motor main body is ensured.

Description

technical field [0001] The invention relates to the technical field of explosion-proof motors, in particular to an explosion-proof stepping motor. Background technique [0002] Explosion-proof motor is a kind of motor that can be used in flammable and explosive places. It does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, in textiles, metallurgy, and city gas , Transportation, grain and oil processing, papermaking, medicine and other departments are also widely used, as the main power equipment, usually used to drive pumps, fans, compressors and other transmission machinery. [0003] During use, although the shell of the explosion-proof motor is not sealed, the flame-proof motor mainly uses the flame-proof shell to separate the electrical parts that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture, which is har...
