Abstract
A dynamometer includes a roller that is rotabably mounted upon a shaft with the shaft being rotatably mounted upon a support that carries the weight of the roller, the dynamometer also having a shear beam load cell disposed within the roller with a first end secured adjacent to an inner surface of the roller and a second end attached to the shaft to provide the sole structural connection between the roller and the shaft.
Claims20
A dynamometer comprising:
- at least one support;
- a roller shaft rotatably mounted upon said support;
- at least one hollow annular roller rotatably mounted upon and supported by said roller shaft with said roller capable of turning freely about said roller shaft, said support carrying the entire weight of said roller and said roller shaft;
- at least one load cell disposed within said roller, said load cell having a first end secured adjacent to an inner surface of said roller and a second end attached to said roller shaft;
- and
- at least one rotatable load driven by said roller shaft, said load operative to cause said load cell to generate a signal that is exclusively a function of torque applied to said roller.
