发明名称 Non-slip continuously variable transmission
摘要 A non-slip continuously variable transmission (CVT) uses the positive engagement of gear teeth and does not rely on friction to transmit torque. The transmission has a ring gear with spur gear teeth at its periphery and conical teeth at its top surface adjacent to an offset circular track. The circular track or channel guide is a slightly smaller diameter than the ring gear and is positioned within the ring gear. Short plates with worm gears pivoted on cantilever brackets are constrained to move within the circular path defined by the channel guide. Due to the offset from the ring gear, a plate traversing this path will engage the conical teeth of the ring gear over a short arc of travel as the worm gear enters and then leaves engagement. This ability to move the ring gear over an arc by passing a worm gear plate around the near region of the circular channel can be reversed in both direction and in principal by having the ring gear move the worm gear plate.
