Title:
POWER TRANSMISSION SYSTEM IN MECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/173634
Kind Code:
A1
Abstract:
This power transmission system 10 is provided with: a variable torque limiter 16 that enables a torque limit value, which is the upper limit value of power transmitted from an input part 21 to an output part 22, to be varied; an input-side displacement sensor 17A that detects the displacement state of the input part 21; an output-side displacement sensor 17B that detects the displacement state of the output part 22; and a control device 19 that controls the power transmission on the basis of the detection results from the sensors 17A, 17B. The control device 19 has: a safety measure control function 25 for blocking power transmission when transmitted power exceeds the torque limit value; a teaching control function 26 for blocking power transmission when teaching; and an operation control function 27 for obtaining a target value of the transmitted power through calculation that takes the target operation and structure of the robot arm 11 into consideration, to adjust the torque limit value so that the power can be transmitted at the target value.
