Series of increase or decrease the speed and increase or decrease the speed

摘要

The present invention using a gear having a circular arc tooth profile, commonality of sharing the component size of the components used from a low gear ratio to a higher gear ratio until it and increase or decrease the speed constituting the increase and decrease the speed over a wide range to achieve with, it is to construct a series of these increasing or decreasing the speed of accommodating the increase or decrease the speed group. A increase or decrease the speed series, it consists of three mechanisms of the low-speed shaft and the transmission mechanism and the high-speed shaft portion, is the increase or decrease the speed group that was constructed by placing each unit and each of the parts to each section . Oscillating internal meshing planetary gear mechanism, by employing a mixed type planetary gear mechanism that combines a planetary type star-type planetary gear mechanism and the two planetary gear mechanisms to the respective increase or decrease the speed, and adaptable to a wide range of gear ratios the increase or decrease the speed group is a series of storage was increased or decreased speed machine.
