REDUCTION GEAR WITH SPEED RATIO CHANGEOVER MECHANISM

Japanese Patent JP2015045353

A

PROBLEM TO BE SOLVED: To provide a reduction gear with a speed ratio changeover mechanism which can withstand a high load, allows a high-speed rotating clutch to rotate in a stable state, and dispenses with a large amount of running costs.SOLUTION: A reduction gear 1 with a speed ratio changeover mechanism comprises: a high-speed side rotation transmission part or a low-speed side rotation transmission part arranged at an input shaft 11 side; a rotation transmission member which is connected to a rotation transmission receiving part arranged at an output shaft 4 side, and transmits the rotation drive of the input shaft 11 side to the output shaft 4 side; and a speed ratio changeover mechanism which moves the rotation transmission member between a first position in which the rotation transmission member is connected to the high-speed side rotation transmission part and the rotation transmission receiving part, and a second position in which the rotation transmission member is connected to the low-speed side rotation transmission part and the rotation transmission receiving part. A rod 6 connected to the rotation transmission member is arranged so as to be pushed and pulled to/from the axial direction of the output shaft 4 in a hollow space of the output shaft 4, and the rotation transmission member is moved to the first position or the second position by pushing and pulling the rod 6 by engagement with the speed ratio changeover mechanism.
