TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2019124338
Kind Code:
A
Abstract:
To provide a transmission system capable of suppressing adverse influence such as overcurrent in an electric motor by properly adjusting a degree of transmission of driving force through a belt between the electric motor and an operation portion, according to the necessity with a simple mechanism.SOLUTION: A transmission adjustment portion 15 is operated by an actuator 16 of which an operation is controlled by a control portion 17, a tension state of a belt 30 can be adjusted by displacing a tension pulley 15a of the transmission adjustment portion 15 kept into contact with the belt 30, the control portion 17 operates the actuator 16 to displace the tension pulley 15a to a side of loosening the tension of the belt 30 when an abnormal state of an electric motor 40 and an operation portion 50a are acquired, so that a degree of transmission of driving force between a driving-side pulley 12 and a driven-side pulley 14 is lowered through the belt 30, thus influence by operation load of the operation portion 50a on the electric motor 40 can be reduced, and an abnormal state that overcurrent generates in the electric motor 40 can be solved.SELECTED DRAWING: Figure 2
