Gearless Transmission
In gear less transmission power is transfered at any angle without any gear being manufactured. El-bow mechanism is used in this type of power transmission which is an ingenious link mechanism of slider and kinematic chain principle.
working Principle
Three links slide relatively according to the motion given to the shaft. Due to this the rotational motion of input shaft is converted in to sliding motion of links which is then converted to rotational motion of output shaft
construction
It consist of cylinder, bent link, bearing. Cylinder are placed at any angle and fastened. A number of pins (between 3 to 8 the more the pins the smoother the operation) slide inside hollow cylinders thus formatting a sliding pair. Power is supplied by an electric motor.
Advantages
1 More efficient than gear.
2 Simpler cooling system.
3 Low cost of manufacturing.
4 Complete freedom of interchangeability.
Application
1Tower clock.
2Gang drilling.
3 Used in vehicles.
