CONTINUOUSLY VARIABLE TRANSMISSION WITH UNIFORM INPUT-TO-OUTPUT RATIO THAT IS NON- DEPENDENT ON FRICTION

Номер: US20190003564A1
Автор: Rajendran Prashanth Ram, Rajendran Raja Ramanujam
Принадлежит:

This invention is an all gear infinitely variable transmission that is non-dependent on friction. It can me be used in high torque applications. It offers a steady and uniform output for a steady and uniform input. It allows a co-axial input and output thereby by using a planetary gear system the output can be made continuous from forward to reverse. This uses a “scotch-yoke” mechanism to convert rotational motion to a linear reciprocating motion. The linear distance of this reciprocating motion-“stroke” is changed by altering the crankpin location of the scotch-yoke mechanism. This reciprocating motion is converted to a rocking motion by using a “rack and pinion” and later converted to a unidirectional motion via a One-Way-Bearing. A set of non-circular gears are used to achieve a steady and uniform output. It employs a very simple mechanism to change the ratio between the input and output of the transmission. 1. An infinitely variable transmission wherein: [{'b': '18', 'a) an Input-Disk having a radial slot with a length extending in a substantially radial direction, disposed between a Ratio-Cam-Disk comprising a non-radial slot extending at least partially in a non-radial direction, and a slotted Cross-Rack-Holder comprising a first slot for receiving a Crank-Pin, a longitudinal axis of the first slot being orthogonal to a longitudinal axis of a Rack coupled with the slotted Cross-Rack-Holder that is restricted to move only along a substantially straight line that is substantially orthogonal to the first slot, a Crank-Pin engaged in the slot on the Input-Disk, the first slot of the Cross-Rack-Holder, and the slot of the Ratio-Cam-Disk , and extending parallel to a longitudinal axis of the Input-Disk,'}, 'b) at least one Rectifier-Module that includes:, 'At least one Scotch-Yoke-Module which consists of 'and c) an Angular-Velocity-Modifier-Module comprising at least one Non-Circular-Gear and an Input-Shaft, arranged such that', 'the Rack, a Pinion, a Shaft-Pinion, ...
