Abstract
The utility model relates to a flame-proof structure at a shaft through position of a four-grade flame-proof motor, comprising a bearing sleeve, a push cover, a push cover block, a flame-proof combined surface between the push cover block and the bearing sleeve, a flame-proof combined surface between the bearing sleeve and the push cover, a flame-proof combined surface between the push cover and the push cover block, a guide key, a flame-proof combined surface between the push cover and a shaft and the shaft, wherein the push cover is arranged between the bearing sleeve and the push cover block, and the flame-proof combined surface between the bearing sleeve and the push cover, the flame-proof combined surface between the push cover and the push cover block and the flame-proof combined surface between the push cover and the shaft are formed, the push cover block is arranged on the bearing sleeve via a bolt, a flame-proof combined surface between the push cover block and the bearing sleeve is formed, and the guide key is arranged between the push cover and the shaft. The structure is simple in structure and reasonable in design. The structure can guarantee that the push cover can freely slide on the shaft so that flame-proof gap between the push cover and the bearing sleeve and flame-proof gap between the push cover and the push cover block can be adjusted, and can avoid shaft locking accidents in the operation of the motor. With a high reliability, the structure can be used in explosive gas environments, such as first zones and second zones, which are defined by hazard classification.
Description
Technical field: the utility model relates to the explosion separation structure of a kind of level Four explosion separation motor axle perforation place.
Background technology: at present, the explosion separation structure of existing level Four explosion separation motor axle perforation place is bent line structure, and its shortcoming is that requirement on machining accuracy is very strict; Mating surface between curved path ring and the bearing holder (housing, cover) does not have regulatory function; In motor operation course, receive factor affecting such as temperature rising, the easy generation rubbed each other between curved path ring and the bearing holder (housing, cover), causes the extremely acute rising of local temperature; Motor seize accident occurs, influence the safe handling of motor in hazardous environment.
Summary of the invention: the purpose of the utility model is to overcome above-mentioned shortcoming; The explosion separation structure of a kind of level Four explosion separation motor axle perforation place is provided; The explosion separation structure that it has mainly solved perforation place of existing level Four explosion separation motor axle is bent line structure; Mating surface between curved path ring and the bearing holder (housing, cover) does not have regulatory function, and friction each other takes place between curved path ring and the bearing holder (housing, cover) easily, problems such as motor seize accident occur.The explosion separation structure that the purpose of the utility model is achieved in that perforation place of level Four explosion separation motor axle is by flame proof faying face, a formation between flame proof faying face between: flame proof faying face between flame proof faying face, bearing holder (housing, cover) and the pushing cover between bearing holder (housing, cover), pushing cover, pushing cover retaining, pushing cover retaining and the bearing holder (housing, cover), pushing cover and the pushing cover retaining, lead key, pushing cover and the axle.Pushing cover is installed between bearing holder (housing, cover) and the pushing cover retaining; Flame proof faying face between flame proof faying face and pushing cover and the axle between flame proof faying face, pushing cover and pushing cover are kept off between formation bearing holder (housing, cover) and the pushing cover; The pushing cover retaining is installed on the bearing holder (housing, cover) through bolt; Form flame proof faying face between pushing cover retaining and the bearing holder (housing, cover), lead key is installed between pushing cover and the axle, and pushing cover can be slided on axle.This product structure is simple; Reasonable in design, the explosion separation structure of product can guarantee that pushing cover is free to slide on axle; And then the flame proof gap between adjusting pushing cover and bearing holder (housing, cover) and the pushing cover retaining; Reduced the generation of motor seize accident in service, security reliability is high, and can be used for classification of risks is in the explosive gas atmosphere in 1 district, 2 districts.
