Compact Cycloidal Magnetorheological Couplings

Abstract

The invention discloses a compact cycloidal wheel magnetorheological coupling. The compact cycloidal wheel magnetorheological coupling is composed of an outer rotary component and an inner rotary component. An outer sleeve is formed by fixedly connecting a magnetizer and magnetism isolating rings which are symmetrically distributed on the two sides in the axial direction, and a multi-turn electromagnetic coil is wound in an annular groove of the outer sleeve. An outgoing line of the electromagnetic coil and a wiring terminal are guided out from the axial side face of an input-end coupling and connected with a power supply slip ring, and the input end is sleeved with the power supply slip ring. The outer-diameter portion of the outer sleeved is sleeved with cooling fins, and the two ends of the outer sleeve are connected with the input end of the coupling and a transparent cover through magnetism isolating screws. Oil injection plug screws are symmetrically distributed and mounted on the axial outer-diameter portion of the transparent cover. Pressure release valves which are symmetrically distributed are mounted at the input-end coupling in the circumferential direction. An outer cycloidal wheel sleeve is formed by fixedly connecting a cycloidal wheel and an inner magnetism isolating ring and is of a hollow barrel-shaped structure, and the two ends of the outer cycloidal wheel sleeve are connected with a rotary flange and an output-end coupling through magnetism-isolating stainless steel screws correspondingly. The inner rotary component and the outer rotary component are connected through a bearing. The compact cycloidal wheel magnetorheological coupling has the advantages of being compact in structure, low in manufacturing cost, convenient to maintain, and capable of transmitting a large torque.

Description

technical field [0001] The patent of the invention belongs to the field of mechanical transmission and control, and specifically relates to a compact cycloid magneto-rheological coupling. Background technique [0002] Traditional couplings are divided into rigid couplings and flexible couplings. The former has a simple structure, but has high requirements for the stability of the transmission process; the coupling using elastic elements in the latter has certain buffering and vibration reduction functions, but the ability to transmit torque is limited according to the performance of the elastic elements. limits. Couplings that use traditional elastic elements as power transmission and damping media are widely used in the field of vibration damping control, but their control methods have disadvantages such as complex technology and high maintenance costs, and are not suitable for high-speed, heavy-duty transmission control. occasion. [0003] At present, research on magnet...

Problems solved by technology

However, these two invention patents still have shortcomings: 1) The transmission torque is too small to be suitable for high-power and heavy-duty occasions

2) It is not convenient for installation and maintenance under the limitation of working space
