Explosion-proof combined permanent magnet or switched reluctance electromechanical all-in-one machine and assembling method

Abstract

The invention relates to an explosion-proof combined permanent magnet or switched reluctance electromechanical all-in-one machine and an assembling method, and belongs to the technical field of explosion-proof permanent magnet motors. The technical scheme is that a planetary reducer (15) is arranged on a reducer base (16); a spline groove (12) is formed in a speed reducer input shaft (10); the end, outside a bearing (11), of a rotor shaft (1) is connected with the speed reducer input shaft (10) through a spline; the speed reducer input shaft and the rotor shaft are coaxial, and a cavity independent space (9) is formed in the joint of a front end cover (8) and the speed reducer base (16); the permanent magnet motor and the planetary reducer are connected into an integrated structure. The invention has the beneficial effects that the cavity independent space is formed in the joint of the motor front end cover and the speed reducer base, the mining motor standard is met, and meanwhile, the working efficiency of transferring, lifting, transporting and other operation is improved.

Description

technical field [0001] The invention relates to an explosion-proof combined permanent magnet or switched reluctance electromechanical integrated machine and an assembly method, belonging to the technical field of explosion-proof permanent magnet motors. Background technique [0002] At present, in the industrial electric drive system, the traditional transmission method is the motor-coupling (or hydraulic coupling)-reducer-roller, etc. This typical equipment configuration has been widely used, especially the high-power system, which still adopts the traditional method, which brings many problems to the on-site operation and maintenance. For example: low transmission efficiency, large operation and maintenance workload, high cost, large space required for equipment layout, large initial project investment, etc. As a motor deceleration transmission, its structure is to apply motors, reducers and other components to the power output conversion of belt conveyors and lifting tra...

Problems solved by technology

However, there are the following problems in the application range and use: (1) At present, the built-in electric drum is generally below 90kW with small and medium power and low voltage, and there are basically no products with optimized application structure, high efficiency and high power transmission; (2) Motor, reducer The built-in structure of the device has the problems of difficult maintenance of oil cooling and oil immersion structure (oil leakage problem, etc.), and high maintenance cost; (3) The traditional transmission structure still has the problem of low efficiency, such as the traditional belt conveyor and conveyor belt The transmission efficiency of the system is generally about 70%

The Chinese utility model patent with the application number 201520581361.X discloses a semi-direct drive permanent magnet motor power assembly; in this structure, the reducer casing is connected to the low-speed permanent magnet motor casing and the shaft extension end cover is jointly composed Machine gear lubricating oil chamber, however, this structural design is not independent of each other, cannot meet the coal safety requirements of mining equipment, and cannot be used in the coal mine operating environment
