Flame-proof type nickel alloy flat-belt pulley motor

Abstract

The invention relates to a motor which is specially used in the field of energy industry. A flame-proof type nickel alloy flat-belt pulley motor comprises a motor case, a front end cover, a rear end cover, a motor spindle, a lead port, a stator, a rotor and a flat-belt pulley. A front cover bearing hole of the front end cover is fixedly provided with a front bearing outer circle. A front bearing section of the motor spindle is fixed in a front bearing inner hole. A rear cover center hole of the rear end cover is fixedly provided with a rear bearing outer circle, a rear bearing section of the motor spindle is fixed in a rear bearing inner hole, the rear end of the rear bearing section is provided with the tail end of the motor spindle, motor impellers are fixed on the tail end of the motor spindle, and an outer cover of the impellers is fixed on the outer circle of the rear end cover. The flame-proof type nickel alloy flat-belt pulley motor is characterized in that gland flanges are arranged between the lead port and a wiring port base on the motor case, the grand flanges fix a sealing hole ring in a port base inner hole of the wiring port base, the front end cover is fixedly provided with separation components, bearings without inner rings are arranged between the separation components and the flat-belt pulley, and nickel alloy hard wear-resisting layers are arranged on the surfaces of component supporting circles of the separation components.

Description

technical field [0001] The invention relates to a special motor in the field of energy industry, which has double strict requirements on size, space and service life, and specifically relates to a flameproof nickel alloy flat pulley motor. Background technique [0002] In recent years, air compressors have developed rapidly in the petroleum, coal, and chemical industries. The motor is the heart of the air compressor, and ordinary motors can no longer meet the requirements of air compressors used in petroleum, coal, and chemical industries. However, ordinary explosion-proof motors must be made very large because of the constraints of electrical clearance and creepage distance. Affected by the limitation of the internal space of the air compressor and the wiring and wiring. To install an ordinary explosion-proof explosion-proof motor, the internal space of the compressor must be enlarged, and the overall volume of the compressor must be further enlarged, and finally the inst...

Problems solved by technology

Therefore, in order to allow the motor shaft to withstand the bending moment, the diameter of the motor shaft has to be doubled, which eventually leads to a series of disadvantages: the linear speed of the motor bearing is also doubled, its internal friction is doubled, and the heat generated by the internal friction is doubled Big
