Internal Geneva Mechanism

Objective:

1) To design 3d Assembly of Internal Geneva mechanism.

2) Simulation of the Internal Geneva mechanism Using MBD.

4) the graph of angular displacement of driven wheel

5) compare the graph of the angular velocity of the driver and driven at 10 and 20 RPM

6) Comparison of the precise contact and non-precise contact force.

Introduction:

Geneva mechanism is used for the transfer continuous rotary motion into the intermediate rotary motion. There are mainly three types of Geneva mechanism internal, external, spherical.

here, in Internal Geneva mechanism, Driver Rotate the Driven Part. The driver is rotating at the constant speed and when its pass from the slot of the driven member its rotate the Driven member.

During this contact, some force is developed between Pin and Contact surface of the driven member. We have to analyze that force. for the precise and non-precise contact also we have to compare the effect of the RPM on contact force, angular displacement, and angular velocity.

Applications:

1)Automation

2) feeding mechanism.
