Gearless Power Transmission 180 Degree
Mechanical Engineering Final Year Project
The Gearless transmission or El-bow mechanism is a device for transmitting motion at any fixed angle between the driving and the driven shaft.
The synthesis of this mechanism would reveal that it comprises a number of pins that would be between 3 to 8, the more the pins the smoother the operation.
These pins slide inside hollow cylinders thus formatting a sliding pair. Our mechanism has 3 such sliding pairs. These cylinders are placed in a Hollow pipe and are fastened at 120 degrees to each other.
This whole assembly is mounted on brackets wooden table. Power is supplied by an electric motor. The working of the mechanism is understood by the diagram.
An unused form of transmission of power on the shaft is located at an angle. Motion is transmitted from driving to the driven shaft through the roads which are bent to conform to the angles between the shafts.
These roads are located in the holes equally spaced around a circle and they are free to slide in & out as the shaft revolves.
This type of drive is especially suitable where quiet operation at high speed is essential but only recommended for high duty.
