Abstract
A machine that converts between reciprocating motion of a piston and rotary motion of a shaft. The shaft rotates an integral web that carries a number of lobe wheels spaced evenly about a pitch circle centered on the shaft. The lobe wheels are planetary driven by pinions and a fixed ring gear. The lobe wheels are somewhat star shaped with radially extending lobes which push followers outwardly, then release them inwardly, as the lobe wheels orbit past and below the follower. The follower is connected by a lever and a pair of connecting rods and to the piston.
Claims14
A machine having:
- a central axis;
- a plurality of lobe wheels each being rotational about its own axis and orbital about a common circular path centred on the central axis and each having a plurality of equally spaced apart radially extending lobes;
- a fixed internal ring gear centered on the central axis;
- a respective pinion gear driving each respective lobe wheel and engaging the ring gear, and the pinion gears all having an equal number of gear teeth;
- at least one reciprocating piston slidable within a respective cylinder;
- and
- a radially reciprocable lobe follower for each piston;
- and
- a respective lever arm pivotable about one fixed end and connected positively between each piston and its respective lobe follower so as to provide proportional synchronous reciprocation of the piston and the follower,
- the number of lobes per lobe wheel and pinion to ring gear ratio being selected in combination such that at spaced apart radial axes consecutive passing lobe wheels have a lobe which is at a maximum radial distance from the central axis and each follower is positioned aligned with a respective said radial axis.
