Abstract

A minitype explosion-proof speed reducing motor is arranged with an explosion-proof casing at the exterior of the minitype speed reducing motor. The explosion-proof casing is composed of an explosion-proof barrel and an end cap with a counterbored hole. The end cap is connected to the explosion-proof barrel through the explosion-proof screw adjoining plane IV, and the back end of the end cap is arranged with an explosion-proof type cable leading-in device. The front end of the explosion-proof barrel is arranged with a shaft hole and a fixing hole. The machine shaft traverses the shaft hole after covering with a prolonging sleeve. The fixing hole is installed with the screw and the hole-blocking plug for fixing the minitype speed reducing motor. An explosion-proof adjoining plane IV is arranged between the outer diameter of the prolonging sleeve and the explosion-proof barrel, and an explosion-proof adjoining plane III is arranged between the hole-blocking plug and the fixing hole. In this way the common minitype speed reducing motor and the outer explosion-proof casing and the explosion-proof type cable leading-in device form a minitype explosion-proof speed reducing motor.

Description

Technical field [0001] The invention relates to a miniature explosion-proof deceleration motor, which is especially suitable for small equipment in underground coal mines, and also suitable for small equipment in other explosive gas environments. Background technique [0002] In explosive gas environments, such as underground coal mines containing explosive gases such as gas, as well as in some petroleum and chemical industries, the motors used must be explosion-proof motors, otherwise there will be a danger of explosion. At present, the motors used in explosive gas environments are mostly flameproof synchronous motors or three-phase asynchronous motors. Flameproof motors are divided into two categories: Class I - flameproof motors for coal mines and Class II - factory flameproof motors. Class I explosion-proof motors for coal mines are often used as power sources for shearers, conveyors, winches, pumping stations, and electric locomotives, so they generally have high power,...
