Abstract
The purpose of the invention is to develop a torque measuring device with measuring points only at one place on the measuring shaft and which is highly sensitive in a given rotation speed range. According to the invention, in a torque measuring arrangement for a gear drive with at least three meshing helically toothed spur pinions, at least one fixed distance sensor on at least one of the pinions is directed towards a plane surface of the pinion which is connected to an evaluation device. The invention is applicable to all gear drives which transfer the power via helical gears.
Claims5
An assembly for measuring a torque in a gear wheel drive, comprising:
- three mutually meshing, helically toothed spur gears rotatably mounted about respective, mutually parallel axes;
- at least one of said spur gears having a planar surface perpendicular to said axes;
- a distance sensor stationarily disposed and directed towards said planar surface of said at least one spur gear;
- and
- an evaluation unit connected to said distance sensor for determining a distance between said distance sensor and said planar surface.
