Step-up or reduction gear series using internally meshing planetary gear structure.

摘要

An internally meshing planetary reduction gear series is disclosed. The user can freely select a type having a small angular backlash or a type without specifying the angular backlash according to the function necessary for the mating-machine (conveyor or the like). The above series include at least two types of a low backlash type having a small angular backlash, and a general type without specifying the angular backlash with the same speed change ratio, mating dimension, and transmission capacity in the same frame number. As a result, in variously assembling the conveyors in the physical distribution system, for example, the conveyors requiring only the movement, or the conveyors requiring the accurate stopping control and the like the assembly can be achieved only by suitably selecting such a reduction gear that only the angular backlash performance is different and the other factors are the same for the same conveyor. Therefore, it is possible to extremely improve the usage of the series. <IMAGE>
