BURKOV LN DESIGN GEAR SET Russian patent published in 2008 - IPC F16H1/06 F16H55/12 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in development of new gear set designs. The gear set consists of drive (1) and driven wheels with teeth made on their surfaces. Teeth (3) of drive wheel (1) represent detachable disks. Roots (4) terminate in a "dovetail"-shape bifurcation. Drive wheel (1) consists of two rigidly coupled parts, i.e. a base and a cover, the latter accommodating centring pins (7) opposite every tooth at the foot of the "dovetail". The base inner side has the "dovetail"-shape blind slots similar to those of the roots of teeth (3) and with an identical pitch along the base upper surface. The outer surface driven wheel has cells with a shape similar to that of tooth (3) of drive wheel (1) and with the same pitch. Conjugation between the said cells and driven wheel surfaces in both lengthwise and crosswise planes are made smooth. The call curvature radius equals that of the camber of tooth (3) of drive wheel (1). The cell depth makes, at least, half the height of tooth (3) of drive wheel (1).

EFFECT: lower contact strain and higher transmitted power.
