Small load double row angular contact ball bearing with integrated speed change function

Abstract

The present invention relates to a small load double row angular contact ball bearing with integrated speed change function. The bearing is mainly used to adjust the speed distribution of mechanism operation in one cycle in the case of small load. The apparatus includes an outer ring, a rolling element, a cage, an inner ring, a magnetorheological suspension, a spacer ring, a solenoid coil, a piezoelectric ceramic and an insulator. The inner wall of the outer ring is provided with two annular grooves; one annular groove is wound by the solenoid coil, and the other annular groove is provided with the piezoelectric ceramic; the insulator isolates the outer ring and the piezoelectric ceramic; the inner ring, outer ring and the spacer ring form a seal cavity for sealing the magnetorheological suspension therein; and the spacer ring isolates the magnetorheological suspension from the solenoid coil; outer wall of the inner ring is provided with a non-annular small projection; the small projection does periodic motion in the annular groove provided with the piezoelectric ceramic; and a channel is between the solenoid coil and the piezoelectric ceramic, and is used for conducing the positive and negative electrodes of the piezoelectric ceramic and two ends of the solenoid coil.

Description

technical field [0001] The invention relates to a double-row angular contact ball bearing, in particular to a double-row angular contact ball bearing with integrated speed change function for small loads. Background technique [0002] With the continuous advancement of science and technology, the efficiency of mechanical equipment has become a hot topic in the industry. Especially in many small and medium-sized enterprises that focus on production, the concept of quantity is very important. In this case, they have invested a certain amount of time. The cost is used to improve the operating efficiency of the machine. However, the internal structure of some improved machines is more complicated, or various hydraulic and pneumatic systems are added externally for speed regulation. If there is a set of devices, without changing the original mechanical structure of the machine or adding an external speed-adjusting hydraulic or pneumatic system, only one part inside the machine ca...
