CAMSHAFT SPATIAL MECHANISM Russian patent published in 2009 - IPC F16H25/12 

FIELD: machine building.

SUBSTANCE: invention refers to the sphere of general machine building and is to be utilised for design of transfer mechanisms enabling rotary-to-reciprocal-and-rotary motion conversion in accordance with specified motion principles. The camshaft spatial mechanism is composed of stationary cylindrical (hyperboloid, cone-shaped) cam, a tooth gear, a rotating link with a stationary bar and a wheel gear and a push bar with a roller. The push bar is connected to the wheel gear and the roller via a swivel joint and a rod-mounted sliding member accordingly. The tooth gear is mounted so that to enable rotation relative to the cam axis and is designed to have two crowns, the major one ("b") and the minor one ("d"). On the rotating link there is additionally an internal gear mounted with a disk having one or more idle gear(s) rigidly mounted onto the cam shaft. The idle gear is simultaneously engaged in the internal gear and the minor crown ("d") of the double-crowned tooth gear.

EFFECT: increase of the rate of the push bar rotation round its longitudinal axis within the limits conditioned by the mechanism overall dimensions preset.
