Variable motion control device and method of use
Variable motion control devices and methods of use. The devices and methods relate to providing an output, such as a rotational shaft output, transmitted from a rotational shaft input, with the output varying based on a control input. The devices and methods are used, for example, to provide a variable output for use with a compressor, power take off, or transmission or differential application. To provide the variable output, the devices and methods include use of mechanical component systems, such as spur gear planetary systems, ring gear planetary systems, bevel gear arrangements, or combinations of such features. The control input is implemented, for example, by arrangements of bindably meshed gears, tension between pulleys joined by belts or similar arrangements of sprockets and chains, use of magnetic clutches, hydraulic or pneumatic controls, or braking devices.
1. A variable motion control device, comprising:
an input shaft having an input end and an output end;
an output sleeve shaft having an attached unit intermediate said input end and said output end, wherein the output sleeve shaft has an opening for sleevably receiving the output end of the input shaft;
a first input shaft gear attached to the input shaft;
a second gear coupled to the intermediate unit, the second gear being meshably engaged with the first input shaft gear;
a third gear coupled to the output sleeve shaft, the third gear being meshably engaged with the second gear;
a fourth gear coupled to the intermediate unit;
a control mechanism having a control mechanism gear attached to a sleeve unit including said fourth gear, said third gear meshably engaged with the fourth gear, wherein the control mechanism provides for variable control of the fourth gear via the control mechanism gear;
wherein variation of the control mechanism varies motion of the fourth gear, thereby varying output of the output sleeve shaft.
2. The device of claim 1 , wherein the intermediate unit comprises an axle.
3. The device of claim 2 , wherein the intermediate unit comprises a second axle.

14. A method for providing a variable output from a variable input using a control, the method including:
receiving an input motion to an input shaft;
transmitting the input motion via a first gear to a second gear meshably engaged with the first gear;
transmitting the motion of the second gear to an intermediate unit, the intermediate unit comprising a hub and axle For mounting said second gear and being intermediate an input end and an output end of said input shaft, the intermediate unit being attached to an output sleeve shaft; and
variably applying an arresting force to the intermediate unit, variable application of the arresting force varying output of the output sleeve shaft.
