Abstract
Abstract A magnetic type transmission wherein a first shaft drives a coaxial second shaft at a greatly reduced speed through the intermediary of a flexible disk which is secured to the second shaft and has at one of its sides an annular surface located opposite the conical surface of a rigid conical frustum. The maximum diameter of the conical surface is less that the outer diameter of the annular surface in undeformed condition of the disk. Successive increments of the annular surface are caused to contact and to travel along the conical surface (whereby the disk rotates with the second shaft relative to the rigid frustum and the first shaft) in response to travel of at least one roller along the other side of the disk opposite the annular surface. The roller is mounted on and orbits about the axis of the first shaft. Alternatively, the conical frustum can attract the annular surface toward its conical surface; the roller is then replaced with one or more magnets which are driven by the first shaft and attract the adjacent portions of the disk so that at least one series of successive increments of the annular surface again travel along the conical surface and the disk rotates with the second shaft at a speed which is a function of the difference between the circumferential lengths of the annular and conical surfaces and the vertex angle of the conical surface.
