Embodiment Construction

[0023] The sensor includes a disc 1 , an inner hub 2 , an outer ring 3 , rivets or bolts 4 for connection, a strain signal transmission line 6 and a strain signal acquisition module 5 . When in use, the inner hub 2 is connected to the transmission shaft through a flat key or spline, the disc 1 and the inner hub 2, and the disc 1 and the outer ring 3 are connected by rivets or special bolts with positioning function, and the sensor uses the inner hub 2, The disc 1 and the outer ring 3 transmit the torque from the transmission shaft to the belt or chain connected with the outer ring. The structure of the disc 1 includes an inner ring 14, an outer ring 11, inclined spokes 12, an inner ring connecting hole 16, an outer ring connecting hole 15, a center hole aD and strain gauges 13 pasted on the inclined spokes. The inner hub structure includes a central hole bD', a keyway 24, a hub 21, an outer connecting ring 22 and a connecting hole 23 on the outer connecting ring for connecting...

Abstract

The invention discloses a split inclined spoke torquer sensor which is mainly used for measuring a rotating torque of a machine system. The sensor comprises a spoke disk, an inner hub, an outer ring, a rivet or a bolt for connecting, a strain signal transmission line and a strain signal collecting module. The spoke disk can transform torque size to a corresponding electric signal and provide for a strain signal collecting module; the inner hub and the outer ring can be processed to be different dimensions and forms according to difference of using conditions, thereby overcoming the shortcoming that the spoke type torque sensor in the past is only directed at one using environment. The sensor is strong in generality, stable and reliable in measurement data; the signal is wirelessly transmitted; the split inclined spoke torquer sensor can be widely applied to torque measurement of laboratories and vehicles of various machinery devices.

Description

technical field [0001] The invention relates to a torque sensor which can replace transmission parts such as pulleys and sprockets. Background technique [0002] The measurement and detection of torque during power transmission is the premise of mechanical system structure optimization and automatic control. The traditional torque sensor mostly uses the transmission shaft as the sensitive element, and the deformation of the transmission shaft is converted into an electrical signal through the strain gauge and then collected and processed. In order to overcome the shortcomings of the axial torque sensor, such as large size, strict centering requirements during installation, and being easily affected by additional bending moments, scientists and technicians invented a spoke-type sensor that obtains torque by measuring the deformation of the spokes of disc-shaped transmission parts such as pulleys and sprockets. However, most of the existing spoke-type torque sensors are direc...
