Magneto-rheological damping structure for rotating motion transmission components

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.
