Internal Geneva Mechanism

Project - Multibody dynamic analysis of internal geneva mechanism using Solidworks.

geneva mechanism -

It is type of indexing mechanism which converts continuous rotating motion into intermitant rotary motion. green coloured part is driver and red coloured part is driven wheel.

All plots shown below are plotted using motion study tool of solidworks.

Procedure -

1)3d Models of driver and driven wheels are created using given dimension.

2)Driver and driven wheels are assembled via required mates.

3)from solidworks motion toolbar motion study is selected.

4)steel(dry)to steel(dry) contact is provided in order to calculate contact force.

4)calculation are carried out.

5)following plots are made based on these calculations-

1)contact force behaviour for normal and precise contact.

2)angular displacement of driven wheel at 10 rpm and 20 rpm

3)angular displacement of driver at 10 rpm and 20 rpm.

Geometry modelling -

1)Geometry of driven wheel -

2)Geometry of driver -
