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, which comprises a motor body and cooling fins. A cleaning component is arranged outside the motor body, and the cleaning component is in contact with the cooling fins. The linkage part, the linkage part is docked with the output shaft of the motor body, and the cleaning part is driven to move on the heat dissipation fins to clean the dust through the output shaft of the motor body. This explosion-proof stepping motor is different from the prior art. Through the combined use of the set cleaning parts and linkage parts, the motor body can automatically clean the dust accumulated at the position of the heat dissipation fins on the motor body during continuous use, effectively ensuring the continuous and effective heat dissipation of the motor body , to ensure its service life.

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. , 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] In the process of use, although the explosion-proof motor casing is not sealed, the explosion-proof motor mainly adopts the explosion-proof casing to isolate 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...
