Description

The previous paper reported on the nutation motor which used air pressure or electromagnetic. In this paper, we report a new type nutation motor of φ10 diameter, named φ10 pneumatic nutation motor consisting of a diaphragm which has some pneumatic rooms, a rotary bevel gear and a fixed bevel gear. Injecting air into each pneumatic room sequentially causes nutation of the rotary bevel gear, which makes the output shaft to rotate through the bevel gears and spherical bearing. In this report, first, the driving principle and design of this motor are presented. Next, the prototype of φ10 pneumatic nutation motor is fabricated and tested. The feature of φ10 nutation motor are (1) simple structure, (2) realization of φ10 diameter, (3) low noise and low vibration, and (4) limitless low speed operation.
