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

AI Thread Summary
The discussion focuses on selecting a suitable ball screw actuator for a reclining mechanism designed to support a 9KN load. The mechanism must raise its weight over a vertical distance of 610mm and requires an actuator that extends by 269mm. Users have explored options from Thomson Linear and reviewed various ball screw catalogs. The actuator must handle a maximum dynamic load of 9KN, with slightly lower static load capacity. Recommendations for the best model are sought to meet these specifications effectively.

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

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
