TORQUE SENSING APPARATUS
First Claim
1. A torque sensing apparatus comprising:
- a torque adjusting assembly having;
a fitting unit having;
a first end; and
a fixed plate mounted on the first end of the fitting unit;
a regulating rod rotatably mounted through the fitting unit and having;
a threaded part formed on the regulating rod and protruding out of the fixed plate of the fitting unit; and
a regulating seat movably mounted on the threaded part of the regulating rod and located outside the fixed plate of the fitting unit and having;
a screw hole formed through the regulating seat, and the threaded part of the regulating rod protruding through the screw hole of the regulating seat; and
a non-contact sensing assembly having;
a first device mounted on the fixed plate of the fitting unit; and
a second device mounted on the regulating seat, wherein the second device is kept from contacting the first device, and the first device or the second device detects a change of distance between the first device and the second device and then generates a signal.

Abstract
A torque sensing apparatus has a torque adjusting assembly and a non-contact sensing assembly. The torque adjusting assembly has a fitting unit, a regulating rod and a regulating seat. The non-contact sensing assembly has a first device and a second device. The regulating rod is rotatably mounted through the fitting unit. The regulating seat is movably mounted on the regulating rod and located outside the fixed plate of the fitting unit. The first device is mounted on the fixed plate. The second device is mounted on the regulating seat and kept from contacting the first device. The non-contact sensing assembly detects a change of the distance between the first device and the second device and generates a signal to a controller, and the controller gauges a torsional value of the torque adjusting assembly. Therefore, the non-contact sensing assembly is not abraded and increases the precision of the torque sensing apparatus.
