TORSIOMETER Russian patent published in 2019 - IPC G01L3/08 G01L3/04 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a measuring technique, intended for measuring torque when power is transmitted through a shaft. Torsiometer contains a shaft with flanges, which is fixed in the housing. Housing is made coaxial with the shaft, with the possibility of rotation of the shaft coaxially therewith, for which the shaft is installed in rolling bearings installed in holes coaxial with the axis of rotation of the shaft, made in the end walls of the housing, the rolling bearings are secured against movement along the shaft. Tool for removing the reference includes two mirrors mounted on the shaft near the end walls of the housing, and a semiconductor laser mounted in the side wall of the housing, with the possibility of forming a beam in a plane perpendicular to the axis of rotation of the shaft, and the possibility of hitting the beam on the first mirror, set at an angle of 45° to the axis of rotation of the shaft, the second mirror is installed with the beam incident thereon reflected from the first mirror, and the possibility of reflection thereof in the plane at an angle to the axis of rotation of the shaft, for which the second mirror is oriented at an angle of 15–45° to the axis of rotation of the shaft and at an angle of 45° relative to the radius of the shaft. Slot is made along the forming body, along which a linear measuring scale is fixed, at zero of which the laser beam reflected from the second mirror is oriented in the absence of a shaft rotation.

EFFECT: ability to measure torque when the shaft rotates at a relatively high speed.
