TRANSMISSION OF A RECTILINEAR OR ROTARY MOVEMENT ON A SINGLE END AND IN A SINGLE DIRECTION

Abstract

In this mechanism, the linear or rotational motion is transmitted from one side to the other in only one direction, while its reverse motion and both other side motion directions can run freely without transmission. To obtain this function of transmitting the motion between both sides in different natures, the link that transmits the motion should be linked with a body which is not controlled by the in-between relative motion. The driving side can oscillate in short strokes or move with unlimited motion, both motion natures can have its own transmission mechanism design. Links could be used in pairs for force balance. One of the ways to transmit the motion from the driving side to the links is by using a waving surface to push and release the link. These waves can be formed in number which is different from the number of link pairs in order to ensure different phases and hence insure contacts of some of them for high and stable transmitted forces and torques. The motion transmission from the link and the motion output body could be through biting, friction or positive engagement in teethed surfaces.

2- A mechanism to transmit the linear or rotary motion from a driving body to a driven body in only one direction as in claim 1, wherein the third body is relatively fixed with respect to the driving body and the driven body, even if it moves with machine in which it is installed.

Description

BRIEF DESCRIPTION OF DRAWINGS

[0016] Drawing (1) is an example of transmitting the linear reciprocating motion from only one body and in only one direction.

[0017] Drawing (2) is an example of transmitting the long linear motion from only one body and in only one direction.

[0018] Drawing (3) is an example of transmitting the rotary oscillating motion from only one body and in only one direction.

[0019] Drawing (4) is an example of transmitting the unlimited rotary motion from only one body and in only one direction.

[0020] Drawing (5) is an example of using two groups in transmitting the rotary oscillating motion to the output shaft in both directions, where friction transmits the motion to the output shaft.

[0021] Drawing (6) is an example of using two groups in transmitting the rotary oscillating motion to the output shaft in both directions, where positive engagement transmits the motion to the output shaft

INDUSTRIAL APPLICABILITY

[0022] The enclosed invention provides a simple mechanism to transform the indexing motion to a continuous stepped motion in both directions without blocking each other. This is necessary to utilize actuators and motors of high torque and limited stroke in building motors that can rotate in both directions, if this is done by reversing gearbox for example, it will be complicated and expensive. Similarly, it can replace the prevailing one-way clutches when the movement of one of the two involved bodies required not to affect the movement of the other body.
