SUMMARY

The discussion centers on designing a sliding plate mechanism with a motor positioned in a constrained space. The original idea was to implement a bell crank mechanism, but the user seeks alternative solutions that incorporate loss motion. Key considerations include maintaining parallelism of the arm to prevent jamming and the flexibility of connecting rods and boss positions.

PREREQUISITES
  • Understanding of mechanical linkages, specifically bell crank mechanisms
  • Knowledge of loss motion concepts in mechanical design
  • Familiarity with motor positioning and its impact on mechanism performance
  • Basic principles of kinematics related to sliding mechanisms
NEXT STEPS
  • Research alternative mechanisms to bell cranks for sliding plate applications
  • Explore designs that incorporate loss motion effectively
  • Investigate the use of pistons in sliding mechanisms
  • Learn about the implications of arm parallelism in mechanical systems
USEFUL FOR

Mechanical engineers, product designers, and hobbyists involved in creating or optimizing sliding plate mechanisms in constrained environments.

Hi all,

I was wondering if anyone had any ideas on something I'm struggling with at the moment. In the attached picture I have a sliding plate that needs to travel as shown. I have a motor mounted in the position on the picture and due to limited space its the only position available. I had intended to use a bell crank mechanism but was wondering if there was anything better? I also would like to include some loss motion somewhere in the mechanism. Any ideas?

The motor will need the arm to remain relatively parallel to avoid jamming. The connecting rods can all change in length if necessary and the boss position could change but id rather it didn't.

Thankshttp://[URL=http://s226.photobucket.com/user/RichRoberts44/media/9_00596_24_zpsjjn45ocm.jpg.html][ATTACH=full]199843[/ATTACH] [ATTACH=full]199844[/ATTACH]

How about how a piston works?

Possibly a cross plate that is driven across the slide plate by the motor.
