ON-LINE CONTROLLABLE HYBRID BEARING AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2020/019742

A1

Disclosed is an on-line controllable hybrid bearing, comprising a main shaft (7), a radial adjustment ring (1), a shaft sleeve (2) and a bearing bush (3). The shaft sleeve (2) is installed on the periphery of the main shaft (7) in a matching manner, the radial adjustment ring (1) is installed on the periphery of the shaft sleeve (2) in a matching manner, and a rotary cavity (4) is formed on the inner side of the radial adjustment ring (1). A bearing bush mounting groove is formed in the shaft sleeve (2). The bearing bush (3) is mounted in the bearing bush mounting groove and is tangent to a sidewall of the rotary cavity (4). The width of the rotary cavity (4) gradually decreases in the counterclockwise direction. Further disclosed is a control method for the on-line controllable hybrid bearing. The on-line controllable hybrid bearing and the control method therefor can solve the problem that the existing hybrid bearing cannot normally work due to the fact that the hybrid bearing cannot adjust the clearance between a journal and the bearing bush (3) at different rotation speeds of the main shaft (7), online control is achieved, and the on-line controllable hybrid bearing and the control method therefor are capable of adapting to different working conditions.
