Lead Screw diameter for lifting 200Kgs

Click For Summary

Discussion Overview

The discussion centers around determining the appropriate diameter for a lead screw designed to lift a weight of 200 kg. The context involves practical application and specifications related to mechanical design.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant describes using a trapezoidal thread and nut for lifting 200 kg and seeks advice on the required screw diameter.
  • Another participant suggests looking up specifications from Nook Industries, proposing that a diameter of 1" / 25mm could be a good starting point, depending on the length for rigidity.
  • A third participant mentions Thomson Linear as another source for lead screw specifications.
  • Another reply emphasizes the importance of consulting supplier recommendations, noting that a smaller screw diameter could suffice for a single lift but may lead to rapid wear.
  • The original poster expresses gratitude and indicates they will seek specifications and may return for further details.

Areas of Agreement / Disagreement

Participants provide various suggestions and sources for lead screw specifications, but there is no consensus on a specific diameter or approach, indicating multiple competing views remain.

Contextual Notes

Considerations regarding rigidity, wear, and the implications of screw diameter on performance are mentioned, but specific assumptions and calculations are not detailed.

Hi
I one of my application i am using the lead screw arrangement to lift 200kg weight using handle
I used trapezoidal thread and nut.
Could anybody suggest the diameter required for lifting the weight of 200kg

Look up "Nook industries", They make lots of lead screws, and would have specs for them... Depending on the length (for rigidity) 1" / 25mm would be a good starting point

Thomson Linear is another
 
Definitely look up recommendations and specifications from a good supplier. If you want to lift the load once you can get away with a much smaller screw diameter (and therefore smaller thread area), at the cost of rapid wear out.
 
Thanx, I will look into that and get the specifications and will get back if I need some more details
