摘要： PROBLEM TO BE SOLVED: To eliminate backlash and quietly transmit high rotation moment by setting the diameter of an inside drive surface of an annular wheel having a planetary gear unit stored therein in such a state as satisfying a specific relation relative to the diameters of the sun wheel and the planetary wheel. SOLUTION: A pot-shaped annular wheel 8 provided with a first inside drive surface 7 and an elastically deformable rim 16 in a housing is supported by its flange part 17 and a planetary carrier 6 integral with the first shaft 9 is rotatably stored in the annular wheel 8. A lot of planetary wheels 3 are journalled to the carrier 6 and a sun wheel 2 on a second shaft 1 is engaged therewith. In this case, the diameter of the inside drive surface 7 of the annular wheel 8 is set smaller than the sum value of the diameter of the inside drive surface 21 of the sun wheel 2 and twice the value of the diameter of the planetary wheel 3 so as to eliminate the backlash.

摘要： PURPOSE: To easily adjust a backlash with a simple gear train. CONSTITUTION: A heilical pinion 12 out of helical gears being engaged with each other is divided into a first pinion 17 and a second pinion 18 in the axial direction, and the first pinion 17 is made to move in the axial direction by energizing a piston 20 by a disc spring 22 while actuating the piston 20 by hydraulic pressure. Adjustment of a backlash is carried out by changing apparent tooth thickness of the helical pinion 12, and adjustment of the backlash in correspondence with high speed rotation from dividing rotation is easily carried out with a simple gear train.
