Abstract

605,876. Gearing. SOC. OLAER-MARINE. June 28, 1945, No. 16524. Convention date, Jan. 6, 1941. [Class 80 (i)] [Also in Group XXIX] To eliminate oblique stresses in a hydraulic motor or other piston machine, Fig. 1, comprising one or more piston and cylinder assemblies, the, or each, slidable piston or cylinder member 6a is coupled at 9a to a pinion 2a mounted on a frame 4 and engaging a gear-wheel 3 of equal diameter rotatably supported on the frame about an axis X-X, the non- slidable cylinder or piston casing F being mounted for relative movement about an axis Y-Y on the gearwheel, whereby the line Y-Y, 9a is always parallel to a line joining the centres of the gear-wheel and pinion. A number of cylinders may be arranged in line or radially about the gear 3. The gear may be stationary while casing F and frame 4 rotate about axes Y-Y and X-X respectively. Alternatively, casing F is fixed while gear 3 rotates about axis X-X and frame 4 has a translatory movement due to rotation of axis X-X about Y-Y. In a further alternative frame 4 is fixed, wheel 3 turns about X-X and the casing has a translatory movement due to rotation of axis Y-Y about X-X. In the hydraulic motor shown in Fig. 3, a radial cylinder block 6a is.mounted on a shaft 30 (axis Y-Y), integral with shaft 40 (axis X-X), carrying fixed gear 3 meshing with pinions 2a, connected at 52a with pistons 1a and rotatably mounted on frame 4 connected to the driven shaft 43. Liquid is supplied and exhausted through channels 60, 61 respectively, to and from recesses 70, 71 in the shaft 30 communicating with the cylinders. In order to eliminate side stresses on the shaft due to liquid pressure, the recesses 70, 71, Fig. 5, are connected respectively to smaller recesses 80, 81 and 86, 87 on the opposite side of the shaft. In a modification, the pinions 2a carry further spur-wheels meshing with a gear secured to the road-wheel of a vehicle; the motor being mounted within the wheel.
