Which Ball Screw Actuator Best Fits a Reclining Mechanism for a 9KN Load?

Click For Summary
SUMMARY

The discussion focuses on selecting the appropriate ball screw actuator for a reclining mechanism designed to support a 9KN load. The mechanism requires an actuator that can extend by 269mm and must raise its own weight through a vertical distance of 610mm. Participants recommend exploring linear motion products from Thomson Linear, specifically their ball screw catalogues, to identify suitable models that meet these specifications.

PREREQUISITES
  • Understanding of ball screw mechanics and specifications
  • Familiarity with load capacity calculations for actuators
  • Knowledge of linear motion products and their applications
  • Basic principles of mechanical design for reclining mechanisms
NEXT STEPS
  • Research specific ball screw models from Thomson Linear that meet the 9KN dynamic load requirement
  • Investigate actuator extension mechanisms suitable for a 269mm stroke
  • Explore design considerations for X framed reclining mechanisms
  • Learn about load distribution and weight management in mechanical systems
USEFUL FOR

Mechanical engineers, product designers, and anyone involved in the design and implementation of reclining mechanisms or linear motion systems.

I have a reclining mechanism which moves by and down. It is X framed, just like an ambulance stretcher. It has to be able to raise its own weight through a vertical distance of 610mm. The length of the stretcher is 2m, and the distance between the wheels is fixed at 1.2m. Can anyone help me go about this...

I've used linear motion products from http://www.thomsonlinear.com/website/com/eng/products/Ball_Screws_and_Lead_Screws.php" to find manufacturers.

hey thanks for the links, I've looked at some of the ball screw catalogues and found a few possible ones. The actuator must extend by 269mm and be capable of providing a maximum dynamic load of 9KN. The static load capacity is just a bit less. What would be the best model?

Thanks
