Abstract:
A mechanical transmission (10) includes a first gear (13), a second gear (15), a slip clutch (14), an input shaft (11), a fourth gear (20), a one-way bearing (21), a third gear (18) and an output shaft (12). The first gear (13) and the slip clutch (14) are mounted on the input shaft (11). The first gear (13) is meshed with the second gear (15) which is mounted on the output shaft (12). The one-way bearing (21) and the fourth gear (20) are mounted on the output shaft (12); the latter (20) is meshed with the third gear (18) which is mounted on the input shaft (11) to constitute a step-down gearing (22). When the load upon the output shaft (12) increases so that the torque imposed upon the slip clutch (14) is higher than predetermined, the slip clutch (14) releases, and the increased torque generated by the step-down gear set (18, 20) drives the increased load upon the output shaft (12). Two additional embodiments (10', 10") are disclosed.
