Abstract
An inductive transformer for transmitting measurement data and/or electrical energy between two components (1, 2) moving relative to one another includes one primary and one secondary transformer part (4, 5), in which a gap is formed between the moving components (1, 2). A slide ring (6; 7), which is made of a plastic with embedded ferromagnetic metal parts is disposed in the gap. The metal parts are distributed nonhomogeneously in the plastic, such that their proportion, on the end with which it is solidly disposed on one of the components (1, 2), is high and becomes relatively slight toward the end with which it rubs against the respective other component (1, 2).
Claims5
An inductive transformer for transmitting measurement data and/or electrical energy between two components (1, 2) moving relative to one another, with one primary and one secondary transformer part (4, 5), in which a gap is formed between the moving components (1, 2), characterized in that
- a slide ring (6;
- 7), which comprises a plastic with embedded ferromagnetic metal parts is disposed in the gap, wherein the slide ring fills the gap between the components (1, 2);
- and that
- the metal parts are distributed nonhomogeneously in the plastic, such that a proportion of the metal parts, on an end with which the slide ring is solidly disposed on one of the components (1, 2), is high and becomes relatively slight toward an end with which the slide ring rubs against a respective other component (1, 2).
