Specialized motor for direct-coupled shot blasting machine

Abstract

The invention discloses a specialized motor for a direct-coupled shot blasting machine. The specialized motor for the direct-coupled shot blasting machine comprises a motor shell and a motor front cover, wherein the motor shell is fixedly connected to the right side of the outer wall of the motor front cover; a rotor central shaft is fixedly connected to the inner center of the motor front cover;a threaded hole is formed in the shaft head part of the rotor central shaft; a sealing end cover assembly is fixedly connected to the front end, connected with a front bearing, of the central shaft; afront oil injection pipe and a motor are fixedly connected to the upper end of the front bearing; a motor hoisting ring is arranged outside the motor shell; a rotor central shaft is loaded inside themotor shell and fixedly connected with a rotor; a rotor enamelled copper wire winding is arranged outside the rotor and is provided with insulating paper and silicon steel sheets; a rear bearing is fixedly connected to the rear part of the rotor central shaft; a rear oil filling pipe is fixedly connected to the upper end of the rotor central shaft; a fan is fixedly connected to the rear part of the central shaft; an air hood is fixedly connected to the rear part of the shell; and a plurality of windings and wiring terminals are arranged inside a wiring box. According to the specialized motorfor the direct-coupled shot blasting machine, the problems of shell tearing and motor bearing dust prevention and lubricating oil leakage prevention caused by low-burning bearings and working vibration in the service life of an existing direct-coupled shot blasting machine motor are solved.

Description

technical field [0001] The invention relates to the technical field of shot blasting, in particular to a special motor for a direct-connected shot blasting machine. Background technique [0002] At present, most manufacturers of motors used in domestic shot blasting machines directly purchase standard motors. Most manufacturers improve the front cover of the motor outside the shaft end of the motor, but the service life of the motor is short, and the problem of burning bearings occurs frequently. The motor shell is also easy to tear. In order to solve the problem of large vibration shell tearing of the direct-connected shot blasting machine motor in the actual application site, the problem of heavy dust pollution of the bearing, and the problem of the central shaft worn by finely crushed steel shots, non-horizontal installation is affected by the axial direction. To solve the problem of burning bearings, we invented this special motor for direct-connected shot blasting machi...

Problems solved by technology

[0002] At present, most manufacturers of motors used in domestic shot blasting machines directly purchase standard motors. Most manufacturers improve the front cover of the motor outside the shaft end of the motor, but the service life of the motor is short, and the problem of burning bearings occurs frequently. The motor shell is also easy to tear. In order to solve the problem of large vibration shell tearing of the direct-connected shot blasting machine motor in the actual application site, the problem of heavy dust pollution of the bearing, and the problem of the central shaft worn by finely crushed steel shots, non-horizontal installation is affected by the axial direction. To solve the problem of burning bearings, we invented this special motor for direct-connected shot blasting machines, which effectively prolongs the service life of the motor, and the comprehensive performance of the dust-proof, shock-proof and burn-proof bearings is excellent.
