Abstract
A kind of controllable worm gearing of wheelchair, including driving motor (1), driving spring (6), transmission gear (7), this wheelchair before the use, pass through control and regulation motor (15);It drives and adjusts U-loop (13) rotation;It adjusts U-loop (13) and drives adjusting screw thread wheel (14) rotation;Adjusting screw thread wheel (14) rotation will make adjusting screw thread wheel (14) move along axis, so as to control the initial elasticity performance of driving spring (6) by adjusting motor (15), and then control the peak torque that driving spring (6) can transmit.In the initial elasticity performance for regulating screw thread, control driving motor (1) is started to work;Driving motor (1) drives transmission shaft (5) rotation;Transmission shaft (5) drives two spring fixed disc (8) rotations;Two spring fixed discs (8) drive driving spring (6) rotation;Driving spring (6) rotation band nutating gear (7) rotates;Transmission gear (7) band movable gear shaft (11) rotates;It can be worked with wheelchair by gear shaft (11) rotation.
