Magnetic coupling reduction box

Abstract

Provided is a magnetic coupling reduction box. The magnetic coupling reduction box comprises an input assembly, a left coupling, a connector, a rack, a magnet assembly, a speed regulation jacket, a roller, a handlebar, an output shaft assembly, a supporting seat, a right coupling and a control mechanism. The input assembly is connected with the output shaft assembly through the magnet assembly, the left coupling is connected with the input assembly, the connector is connected with the rack, the speed regulation jacket is connected with the output shaft assembly through the roller, the output shaft assembly is connected with the right coupling, the control mechanism is connected with the output shaft assembly, and the handlebar is installed on the speed regulation jacket. The magnetic coupling reduction box has the advantages of solving the problems that speed change classification in existing mechanical transmission is high in energy consumption and cost and difficult to maintain, does not have overload protection, or hidden safety risks and shakes exist on the overload protection, the overload protection influences service life of other components and the like, solving the problems to the maximum, and achieving safe operation.

Description

technical field [0001] The invention relates to the field of magnetic transmission devices, in particular to a magnetic coupling speed reducer. Background technique [0002] In the coal mining industry, production safety has become the most important issue restricting coal production. The safety guarantee mechanism of coal mining enterprises is a multi-factor, multi-link, dynamic and complex operating system. To reverse the passive situation of safety production in coal enterprises, we must pay attention to the development of safety technology and equipment, and eliminate unsafe factors from the details. [0003] At present, most of the transmission devices used in coal mines are traditional and backward mechanical transmissions. This kind of transmission device is not targeted in the application of coal mine production. Many details cannot meet the safety standards of coal mines, and there are energy consumption and easy Disadvantages such as wear and tear. As coal mine ...

AI Technical Summary

Problems solved by technology

In this case, most of the mechanical transmission devices used are not targeted for coal mine production, have poor safety and have a series of problems such as high energy consumption and low life, which have brought hidden dangers to the safe production of coal mines.

[0004] First, due to the complex structure of the mechanical transmission when realizing stepless speed regulation, the complex structure increases the workload and cost of maintenance, while the stepped speed regulation has the problem of high energy consumption

[0005] Second, during mechanical transmission, the rotation is achieved by the meshing of the gears. Long-term meshing will reduce the life of the gears and affect the normal operation of the mechanical equipment.

[0006] Third, the traditional mechanical transmission has vibrations when starting and stopping, and affects the service life of other components

[0007] Fourth, the traditional mechanical transmission is difficult to achieve overload protection, and there are great safety hazards
