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

Abstract

The invention relates to a special motor in the field of the energy industry, in particular to an explosive-proof synchronous belt chromium alloy motor. The explosive-proof synchronous belt chromium alloy motor has double strict requirements for scale space and service life. The explosive-proof synchronous belt chromium alloy motor comprises a motor shell, a front end cover, a rear end cover, a motor spindle, a lead pin seat, a stator, a rotor and a synchronous pulley. A front bearing outer circle is fixed to a front cover center hole of the front end cover, and a front bearing section of the motor spindle is fixed to a front bearing inner hole. A rear bearing outer circle is fixed to a rear cover center hole of the rear end cover, and a rear bearing section of the motor spindle is fixed to a rear bearing inner hole. The explosive-proof synchronous belt chromium alloy motor has the advantages that a terminal box is fixedly connected to an internal lead outlet of the motor shell, a terminal box end cover is arranged at the outer end of the terminal box, the lead pin seat is located on the terminal box end cover, and an external lead penetrates through the lead pin seat. The lead pin seat is located on the rear end cover, and a cable penetrates through the lead pin seat. Anti-bending-moment components are fixed to the front end cover, and needle bearings are arranged between the anti-bending-moment components and the synchronous pulley.

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 synchronous belt chrome alloy 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...
