      Hello Everyone,

      I am designing a small sub-assembly consists of two parts. These two cylindrical parts OD= 1.75" and ID 1.25" are assembled using threading because it can be easily disassembled while doing maintenance. However, there is some constraint when this sub-assembly get together with other to become a whole assembly, due to which we cannot use thread. Is there is any way we can replace thread without adding any additional part?

      I have attached a file for reference.

      Thanks in advance
      Akshay

      Hi Akshay

      Without the knowledge of the end use of the product its very difficult to give you any advice on viable options. But in general you could consider the following methods
      • Bayonet connection
      • Self-holding machine taper (Morse taper)
      • push in with built in clips
      • Interference fit
      Hope this helps. Keep us posted of the final design..

      Thanks, Senthil
      Actually, this part is a piston that will reciprocate inside the cylinder. There would be check valve inside it. SO during maintenance to change check valve, two parts should be easily able to take apart and assemble. That's why I used threading at first place. Do you think morse taper will be able to do this job?
