Embodiment Construction
[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0009] exist figure 1 Among them, the present invention is used for thrust cylindrical roller bearings with integrated speed change function for small loads. The device is mainly composed of a shaft ring 1, a seat ring 2, a rolling element 3, a cage 4, a magnetorheological fluid 5, and an electromagnetic coil 6 , isolation ring 7, piezoelectric ceramics 11, and insulator 12. There are two annular grooves on the upper surface of the seat ring 2, one of which is wound with an electromagnetic coil 6, and the other annular groove 10 is installed with a piezoelectric ceramic 11, and the seat ring 2 is isolated from the piezoelectric ceramic 11 by an insulator 12 The shaft ring 1, the seat ring 2 and the isolation ring 7 form a sealed cavity, and the magnetorheological fluid 5 is sealed in it, and is isolated from the electromagnetic coil 6 by the ...
