Abstract
A rotary position transducer assembly for a rotary connection on a work machine, between a first rotary element and a second rotary element, includes a rotary position transducer and a roll-off element coupled to the rotary position transducer, configured to roll off on the circumferential area on the first rotary element. The rotary position transducer detects a rotational movement about a first rotational axis of the roll-off element. The rotary position transducer assembly further includes a bearing securing the roll-off element to the second rotary element such that the roll-off element can be translationally adjusted to vary a distance between the roll-off element and the first rotary element.

Rotary position transducer assembly for a rotary connection on a work machine, between a first rotary element and a second rotary element, the rotary position transducer assembly comprising:
- a rotary position transducer;
- a roll-off element coupled to the rotary position transducer and configured to roll off on the circumferential area of the first rotary element, wherein the rotary position transducer detects a rotational movement about a first rotational axis of the roll-off element;
- and
- a bearing securing the roll-off element to the second rotary element the such that the roll-off element can be translationally adjusted to vary a distance between the roll-off element and the first rotary element.
A rotary position transducer assembly for measuring the rotation between a first rotary element and a second rotary element, the rotary position transducer assembly comprising:
- a base having an opening and a means for securing the base to the second rotary element;
- a cam disposed proximate the opening, the cam having a first axis of rotation;
- a clamping means for fixing a rotation of the cam relative to the cam base;
- a rotary position transducer coupled to the cam, the rotary position transducer having a second axis of rotation offset from the first axis of rotation;
- and
- a roll-off element rotationally coupled to the rotary position transducer.
