DEVICE TO MEASURE TORQUE TRANSMITTED BY POWER TAKE-OFF SHAFT Russian patent published in 2013 - IPC G01L3/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to a device for torque measurement, comprising: a power take-off shaft (12) for transmission of rotation torque around the axis (A) of the power take-off shaft; the first wheel (18), comprising corner marks, besides, the specified wheel is attached to the power take-off shaft; a support shaft (20), comprising the second wheel with corner marks; and a sensor (26), arranged opposite to at least one of wheels with the possibility to determine the torque, transmitted by the power take-off shaft, according to the invention; the first wheel (18) comprises the first and second sequences of corner marks; and the second wheel (22) comprises the third and fourth sequences of corner marks, besides, the marks of the first and third sequences are mutually parallel, and marks of the second and fourth sequences are mutually parallel and are arranged at the angle relative to the first axial plane, comprising the axis (A), besides, the marks of the first sequence are arranged at the angle relative to the marks of the second sequence, and thus the signal generated by the specified sensor (26), it also characterises temperature of the power take-off shaft (12).

EFFECT: development of a device for torque measurement transmitted by a power take-off shaft, simplified design, reduced weight and cost.
