Control and conversion engine etc. drive - has several rotors, each with oval gearwheels, eccentric, parallel, and symmetrical w.r.t. rotor axis

摘要

The drive has a housing with two irregularly rotating rotors, forming working chambers, and non-circular toothed gears to control the rotary oscillating movement of the rotors. Eahc rotor has at least two similar eccentric, parallel, symmetrical oval gears, with an externally toothed belt on the jacket. Each oval gear (12) of the first rotor (2) meshes with two mirror-like oval gears (13) of the second rotor (3), with varying axle distances. The oval gear set controls the rotary angle differential of the two rotors. At least one oval gear is planetary guided w.r.t. the housing (1), directly or via more rotary parts. USE/ADVANTAGE - For engines, turbines etc., with compact design, small number of components and quiet run.
