Inventor: SIMON DIETRICH DR
IPC: G01V1/00

Patent DE-4239861-A1 (DE)
Inventor: IFRIM VASILE DR
IPC: F16H1/32
Filed: 1992-11-27
Abstract: An epicyclic roller gear (10) has two round bodies, in particular rings (1) and (4), provided with a profile or teeth at their inner or outer circumference, and a driving shaft (2), by means of which pressing elements, in particular epicyclic rollers (3), bring individual segments (6), which have complementary profiles and are radially adjustable independently from each other, into engagement with above said profiles of the round bodies. Since these round bodies or rings (1 and 4) have different numbers of teeth and one ring (1) is fixed, whereas the other ring (4) rotates, a relative displacement is achieved, and thus also a high reduction ratio between input and output. In order to guide the segments (6) in a reliable but mutually independent manner without axial guiding rings or mutually coupling the individual segments (6) into a segment chain, the individual segments (6) which are directly adjacent to each other in the circumferential direction are mounted individually and independently from each other in a deflectable manner against the restoring force of two parallel bar or preferably leaf springs (7) fixed to each other. The springs (7) are arranged behind each other in the radial direction but their larger width extends in the circumferential direction. The segments (6) may thus be individually deflected parallel to their own direction, so that a precise engagement and thus a displacement on the rotary round bodies or ring (4) may take place with a high efficiency.
