Special permanent magnet coupler for vibration device

Abstract

The invention relates to the technical field of couplers, particularly relates to a special permanent magnet coupler for a vibration device. The special permanent magnet coupler comprises a base, thebase comprises a supporting plate installed on the ground and a supporting base arranged above the supporting plate, and an outer sleeve is arranged above supporting sea and is a cylindrical shell. Amagnet assembly is arranged in the outer sleeve and comprises an input magnet assembly and an output magnet assembly, the input magnet assembly and the output magnet assembly are connected through a connecting body, and the left side of the outer sleeve is connected with an input assembly. An output assembly is arranged at the right side of the outer sleeve, the input assembly and the output assembly are each provided with a heat dissipation structure, the heat dissipation structure comprises a plurality of small heat dissipation fins and large heat dissipation fins, and the small heat dissipation fins and large heat dissipation fins are distributed at intervals. According to the invention, the problems of poor heat dissipation performance, high working temperature and low device reliability generally existing in the prior, and the situations that the conventional permanent magnet coupler can only work at a speed close to a rated rotating speed, cannot work at a larger slip, and cannotachieve the effects of energy conservation and consumption reduction, are solved.

Description

technical field [0001] The invention relates to the technical field of couplers, in particular to a special permanent magnet coupler for vibration equipment. Background technique [0002] In industries such as metallurgy, chemical industry, electric power, cement, water affairs and machinery, there are a large number of loads such as pumps, fans, compressors and other mechanical devices driven by motors. These existing devices generally use elastic pin couplings, Mechanical couplings such as diaphragm couplings and steel ball couplings connect loads and motors, and most systems have the problems of relatively large starting torque, large vibration, and high energy consumption. [0003] In order to solve the problem of large starting torque, some devices also use a hydraulic coupling and a special soft starter to replace the coupling to connect the load and the motor to reduce the starting torque, but the hydraulic coupling has low efficiency, oil leakage and occupation. The...

Problems solved by technology

[0003] In order to solve the problem of large starting torque, some devices also use a hydraulic coupling and a special soft starter to replace the coupling to connect the load and the motor to reduce the starting torque, but the hydraulic coupling has low efficiency, oil leakage and occupation. The problem of large space, the general soft starter needs a special control system, there are problems of complex system and inconvenient use and maintenance

[0004] Now, permanent magnetic couplers specially designed to solve the above problems have been developed on the market, but these permanent magnetic couplers generally have the problems of poor heat dissipation, high operating temperature and low equipment reliability, and can only work at rated speeds Nearby, it cannot work with a large slip, and cannot play the role of energy saving and consumption reduction
