Abstract
A reaction arm for use with a torque generating device, the reaction arm including a reaction bar, and a body portion having a first internal diameter, and having formed on an internal surface thereof a female spline having a second internal diameter and a guide bushing having a third internal diameter, the first, second, and third internal diameter being distinctly sized.
Claims11
A reaction arm for use with a torque generating device, the reaction arm comprising:
- a body portion having a first internal diameter and a first exterior diameter;
- at least a second element extending longitudinally from said body portion and having a second internal diameter, wherein said second element includes an internal female spline which engages a male spline of the torque generating device, and an internal surface of said body portion having said first internal diameter engaging a housing portion of said torque generating device, wherein said female spline and male spine prevent the reaction arm from rotating with respect to said torque generating device;
- and
- a third element including a reaction bar and a guide bushing, said third element extending longitudinally from said second element, said guide bushing having a third internal diameter, and said third element having a third exterior diameter smaller than said first exterior diameter,
- said first, second, and third internal diameter being distinctly sized, and
- said second element having an exterior surface tapering from said first exterior diameter to said third exterior diameter.
3 more elements
A reaction device, comprising:
- a head of a torque generating device;
- and
- a reaction arm connectable to said head of said torque generating device,
- said reaction arm comprising:
- a reaction bar;
- and
- a body portion including an internal female spline, wherein said internal female spline engages a male spline of said torque generating device, and an internal surface of said body portion having a first internal diameter engages a housing portion of said torque generating device, wherein said female spline and said male spine prevent the reaction arm from rotating with respect to said torque generating device;
- wherein said body portion of said reaction arm wraps around said head of said torque generating device, such that an internal surface of said body portion engages a housing portion of said torque generating device, and said female spline engages an external male spline disposed on an exterior of said housing portion.
