MOUNTING ADJUSTING DEVICE IN AXIAL DIRECTION OF REDUCTION MAIN SHAFT IN REDUCTION GEAR WITH MOTOR

Japanese Patent JP3269012

B2

PROBLEM TO BE SOLVED: To obtain a mounting adjusting device in which the normal engagement of a motor output shaft with a reduction main shaft is maintained, by a method wherein an adjusting annular system is installed in the mounting position in the axial direction of the reduction main shaft.
SOLUTION: A thrust bearing 7 is sandwiched and mounted on a reduction main shaft 1 between a radial bearing 3 and the reduction main shaft 1. An annular system 6 which advances and finely adjusts the mounting position in the axial direction of the reduction main shaft 1 is sandwiched and mounted between the radial bearing 7 and a reduction-gear housing RH. Consequently, the outer ring of the thrust bearing 7 presses and fixes the annular system 6 to the reduction-gear housing RH, and its inner ring is turned together with a reduction transmission gear 1B on the reduction main shaft 1. As a resut, the thrust load of the reduction main shaft 1 is received by the thrust bearing 7, and the annular system 6 is not slid direction by the rotation of the reduction transmission gear 1B. The annular system 6 is sandwiched and pressed between the unrotational outer ring of the thrust bearing 7 and the reduction-gear housing RH. The fine adjustment in a direction opposite to a thrust in the mounting position in the axial direction of the reduction main shaft 1 is maintained and held. The normal engagement of a motor output shaft with the reduction main shaft 1 is maintained.
