ABSTRACT:
Hollow shaft reduction gear with overload protecting device facilitating adjusting the torque of the overload protecting device and repairing the device. A drive plate (8) is axially slidably mounted on one end portion of a hollow output shaft (2) projecting outside from a gear case (1). The drive plate is restrained from rotation relative to the hollow output shaft (2). A driven plate (11) is fixedly mounted on one end portion of a driven shaft (7) projecting from the extremity of the end portion of the hollow output shaft (2) so as to confront the drive plate (8). An interlocking recess (13) and a holding recess (14) are formed in the confronting surfaces of the drive plate (8) and the driven plate (11) respectively, and a ball 15 is held between the recesses (13, 14). The drive plate (8) is biased toward the driven plate (11) by a spring (16). When an excessive load torque acts on the driven shaft (7), the ball (15) moves out of the interlocking recess (13) and the driven plate (11) slips relative to the drive plate (8). The biasing force of the spring (16) is adjusted by a spring-pressure adjusting nut (18).
