PROBLEM TO BE SOLVED: To provide a floating gear speed reducer having a rational structure, convenient for use, low in a manufacturing cost, advantaging realization of mechatronic automation control, and having high reliability.SOLUTION: Provided are a floating gear speed reducer including a front planetary gear system, a rear planetary gear system and a floating gear 1, and a floating gear zero crossing multistage transmission. The sizes of the gears contained in the front planetary gear, the rear planetary gear and the floating gear are designed so as to be different from each other, thereby to obtain any different speed reduction ratio.SELECTED DRAWING: Figure 1 |
