Title: Improvements in or relating to infinitely variable gears
IPC: F16H33/10
Filed: 1947-03-11
Abstract: 622,337. Gyroscopic apparatus. BIASI, F. March 11, 1947, No. 6812. Convention date, Nov. 22, 1945. [Class 97 (iii)] [Also in Group XXIV] In a variable-speed gearing having a fly-wheel mounted in support and countersupports connected respectively to the driven and driving shafts, and in which the gyroscopic properties of the fly-wheel are used to obtain automatic variation of output torque and speed, means are provided to reverse the direction of rotation of the flywheel intermittently so as to obtain unidirectional drive. As shown, a fly-wheel 2, Fig. 2, turns in a frame 4.which is itself rotatable in a second rotary frame 6 driven from the driving shaft 7 and is connected by bevel gearing 10, 9 to the driven shaft 8. The fly-wheel is powered by independent electro-mechanical or hydrodynamic means capable of driving in both directions. Every time the frame 4 precesses through 180 degrees about the frame .6, the fly-wheel is stationed by spring-loaded braking members 12 on the frame 4 and is then driven in the reverse direction to maintain a unidirectional torque on the driven shaft 8. The braking members 12 are operated by cams 16 on the frame 6. In Figs. 3a. 3b and 4 there is no independent power input and a fly-wheel constituted by a moving mass of fluid such as high density oil is utilized. A spherical annulus 20 filled with fluid is rotatable about bearings 21, Fig. 3b, in a rotary driving frame 6a, and is divided into sections by vanes 22, Fig. 4. Diametrically opposed sections extending through about 60 degrees of arc are interconnected by conduits 28 at one pole and are connected at the other pole to ports 24, 26, each alternately communicating with inlet and outlet supply conduits 50, 52 in the frame 6a, so that as the annulus rotates the direction of fluid motion therethrough is reversed twice in each revolution. The annulus 20 drives an intermediate shaft 32 through bevel gearing 30, 31. Planet gears 34, Fig. 3a, on a carrier 36 on the ultimate drive shaft 8a mesh both with a sun 33 on the shaft 32 and with internal teeth on a drum 39 driven from the frame 6a through gears 41 rotatably mounted on the fixed gear casing. The rate of fluid-flow through the annulus 20 is varied in accordance with the relative speeds of the driving and driven members by means of a pump driven by the gearing as shown diagrammatically in Fig. 3a. Gears 72, 75, actually meshing gears 73, 76 on the carrier 36 and drum 39, are connected to the sun 70 and ring gear 74 of an epicyclic gear, the planet carrier 68 of which powers a pump 62 supplying fluid to the annulus 20 through casing ports 56, 60, communicating with the conduits 50, 52. The direction of circulating of the fluid in the system may be reversed by a cock 65, when. the driven shaft will rotate oppositely to the driving shaft. Gearing of this nature may be provided with a solid flywheel controlled electromagnetically or hydrodynamically.
