Title:
TORQUE DETECTING DEVICE FOR A FLEXIBLE MESHING TYPE GEAR
Document Type and Number:
WIPO Patent Application WO/1997/021991
Kind Code:
A1
Abstract:
An approximate straight line A1 of detected values showing magnetic impedance changes relative to a torque change obtained at an end portion (31a) of a body portion (31) of a cup-like flexible external gear (3) of a flexible meshing type gear inclines oppositely to an approximate straight line A2 of detected values showing magnetic impedance changes relative to a torque change obtained at a boundary portion (4) between a diaphragm (32) and a boss (33) of the flexible external gear. It is possible to obtain based on these two approximate straight lines A1, A2 a torque detecting characteristic A3 that passes through a zero point and has a linearity. As a result of this, it is possible to realize a torque detecting device that can detect the rotational torque of the flexible meshing type gear with a configuration different from a conventional one and with accuracy. Based thereupon, it is possible to detect the rotational torque of the flexible meshing type gear with accuracy.
