Overload inhibiting torque meter
Last updated:
Abstract:
Embodiments are directed to a drive shaft apparatus comprising a first rotary member and a second rotary member arranged coaxially with said first rotary member. The rotary members are fixedly connected at a first end so that they rotate together. Each rotary member has a set of elements spaced apart around its circumference at a second end. The elements on the first rotary member are spaced apart from the elements on the second rotary member at rest. The first rotary member undergoes torsion when a load is applied during rotation, which causes the first rotary member elements to move closer to the second rotary member elements. The first elements engage the second elements when a torque load less than a yield torque is applied to the first rotary member, which transfers at least a portion of the torque load to the second rotary member.
