Meshing with each toothing (14, 15, 114, 115) is a pinion of a pair of pinions (16, 25, 116, 125) carried by parallel shafts (17, 22, 117, 122) interconnected with each other by a driving gear (20, 21, 120, 121) to rotate at the same speed and in opposite ways. One of said parallel shafts is the power-input shaft (17, 117). The ring gear (12, 112) is carried by the output shaft (10, 110) in a floating manner to vary the distance of its toothings (14, 15, 114, 115) from the axis of the pinions (16, 25, 116, 125).

Abstract: A continuously variable gear transmission has a hemispherical drive gear providing an axially varying pitch diameter and an axially varying effective circular pitch, and a driven gear with a constant pitch diameter having teeth tapering axially in an opposite sense to the axially varying effective circular pitch of the drive gear. A pitch control drum guides teeth of the driven gear relatively around the shaft axis to continuously vary their effective circular pitch to match a circular pitch of the teeth of the drive gear for ensuring meshing engagement throughout the varying axial positions, whereby the velocity ratio of the transmission is varied continuously. The control drum has a guiding surface extending therearound with an axially tapering, conical guiding portion providing an arcuate guiding surface portion of constant transverse and continuously axially varying radius.

Abstract: A variable torque transmission includes at least one disc-shaped gear 30 having a circular toothed surface 36 with flat beveled teeth 32 that mate along radius 38 with the cone-shaped teeth of pinion gear 10 to produce an infinitely variable lever arm and thus infinitely variable torque while allowing a constant rotation ratio between the drive shafts of the flat beveled gear 30 and pinion gear 10. The result is that the drive shaft energy input may be constant and thus energy efficiency may be maximized while torque may be selectively varied.

Abstract: For some powered drum winches, e.g. in sailing boats, it is desirable that the drum can be driven with two different speeds. Basically, this is no technical problem, but it has been difficult to achieve both a high efficiency and a simple construction. It has been proposed that with the use of a plural shaft gear an advantageous result is obtainable in making the gear drive the drum with two different speeds based on a reversible driving motor being driven in one or the opposite direction. This control principle is also used in the present connection in which, however, it is disclosed how the relevant gear can be designed in a compact and inexpensive manner about only a single gear shaft.

Abstract: In a face gear transmission with a cylindrical pinion and a face gear meshing therewith the toothing of the face gear is derived from a theoretical profile (22) of a pinion with an infinitely small thickness by moving the centre of this pinion along an imaginary axis which the coincides with the axis of rotation of the cylindrical pinion. The teeth of the face gear are crowned so as to achieve the required tooth clearance. The shape of the teeth of the face gear is such that upon the movement of the theoretical pinion profile (22) in the direction of the imaginary axis of rotation, starting from a defined diameter between the maximum and the minimum diameter of the toothing of the face gear, the centre of the theoretical pinion profile undergoes a displacement (P.sub.1, P.sub.2) at the same time at right angles to the imaginary axis of rotation in the direction towards the toothing of the face gear.

Both the first face gear and the second face gear include thrust bearings, which are located radially outwardly of the first face gear teeth and radially inwardly of the second face gear teeth.

Abstract: A self-contained speed control device and system, primarily for electric and hybrid vehicles, includes a self-contained mechanical variable-speed control device. The device allows the motor to run constantly at its most efficient speed and temperature. The device is mechanically operated and connected to the motor and drive train.

A continuous gear and slide arrangement creates a constantly variable speed combination, without interruption, giving the electric motor the feel of an internal combustion engine, without the disadvantage of building torque.

A drive member is provided for selectively rotating one of the wheels and a spring assembly is provided for biasing the wheels toward one another in a direction perpendicular to the first axis.

Abstract: A gear combination is disclosed in which a spherical body has a plurality of grooves defined therein into which a pin gear enmeshes. Substantially all the pins on the pin gear engage the grooves in the spherical body at all times. The spherical body rotates about a first axis and the pin gear rotates about a second axis. The grooves are cut into the spherical body by a computer-controlled milling machine. The groove is endless or eventually returns to its beginning position. The axis of the milling tool may be oriented at any angle with respect to the axis of the lathe head, since the resulting motion of the milling tool necessarily cuts whatever lissajous shape is dictated by the relative periodic motions of the lathe head and milling table. The pins in the pin gear thus follow the grooves defined in the spherical body so that the rotation of the pin gear relative to the spherical body mimics the relative motions of the lathe head and milling table when the spherical body was cut.

Abstract: In a high-loaded, light-weight, compact, multi-stage gear transmission unit with at least one stage with non-parallel shafts, and a transmission ratio between approximately 70 and 150, like a helicopter transmission, said angle transmission generally forms the weakest link. By adoption of a face gear/cylindrical pinion-stage instead of the commonly used bevelled-stage, not only a more reliable drive is possible, but its efficiency is higher, due to less friction, its size is smaller, its adjustment is simpler such that straight forward replacement becomes possible, and--not in the least--the transmission ratio of said angle drive tends to high ratios in contrast to known bevelled-drives which tend to low ratios. In many cases one or even more stages less become possible, providing a further important reduction in weight and size.
