Title:
歯車オーバードライブを伴う軌道トランスミッション
Document Type and Number:
Japanese Patent JP2008546959
Kind Code:
A
Abstract:
The transmission (400) includes an orbital gear complex (404, 416) in combination with a variable hydraulic pump (408) and motor (406). The input (420) to the transmission is increased in speed by the orbital gearing such that, when the pump and motor are not operating, the orbiter (404) is stationary, and the orbital gearing produces an overdrive condition. A gear reduction is accomplished by rotating the web (426) with the web-rotating device (403), providing a high gear reduction. The pump and motor are preferably long- piston hydraulic machines (110) with infinitely variable swash plates. The hydraulic machines preferably have wobblers stabilized by full gimbals and hold-down plates with elongated holes for the long pistons to eliminate possible impacts between the hold-down plates and the head ends of the long pistons when the swash-plates are at or near their maximum angle of inclination.
