Patent ID: 11307105

Abstract:
A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.
