Magneto-rheological vibration reduction structure for rotation transmission part

Abstract

The invention discloses a magneto-rheological vibration reduction structure for rotation transmission part. The magneto-rheological vibration reduction structure comprises an inner core and an outer shell which sleeves the inner core and matched with the inner core in a sealed manner. The inner core and the outer shell are of an annular structure. An annular passage I and an annular passage II which are communicated are peripherally disposed between the inner core and the outer shell. The annular passage I and the annular passage II are filled with magneto-rheological media. The vibration reduction structure further comprises an excitation source for generating a magnetic field to change the shearing yield strength of the magneto-rheological media. The excitation source corresponds to the annular passage II and is peripherally disposed on the inner core or the outer shell. The magneto-rheological vibration reduction structure is simple, good in vibration impact resistance, good in adaptability, capable of reducing abrasion of the rotation transmission part such as a bearing, a bearing block and a gear during transmission, capable of reducing noises, and capable of prolonging the service lives of the bearing block, the bearing, the gear and other connectors.

Description

technical field [0001] The invention relates to the field of mechanical transmission vibration reduction, in particular to a magneto-rheological vibration reduction structure for rotating motion transmission components. Background technique [0002] Bearing housings, bearings and gears are commonly used mechanical parts in the field of mechanical transmission, and they are also important parts in contemporary mechanical equipment. In the transmission process of existing bearings, bearing housings and gears, due to the existence of vibration, parts will be worn, noise will be generated, and the service life of devices will be reduced. How to improve the structure and reduce the impact caused by the impact vibration of the equipment, It is a major technical problem that needs to be solved at present. Contents of the invention [0003] In view of this, the present invention provides a magneto-rheological damping structure for rotating motion transmission parts. The wear of ...
