Discussion Overview

The discussion revolves around resolving mating issues in SolidWorks for an axial piston pump design. Participants explore challenges related to the assembly of components, specifically the mating of slipper pads to a swashplate, and adjustments to the swashplate angle.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant describes difficulties in mating slipper pads to a swashplate in SolidWorks, noting that the pads rotate freely in the piston assembly but not in the full pump assembly.
  • Another participant suggests that the issue may stem from mixing mates from subassemblies with those from higher assemblies, questioning the use of flexible subassemblies.
  • A later reply indicates that the initial problem was resolved, but a new issue arose regarding the adjustment of the swashplate angle.
  • One participant mentions the need for a precise order of mates for successful assembly, while also noting a concern about low RAM affecting performance.
  • Several participants express the need for visual aids, such as pictures of the assembly, to better understand the issues being faced.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to resolve the mating issues, as multiple perspectives and suggestions are presented without definitive agreement.

Contextual Notes

Limitations include potential misunderstandings due to terminology differences and the complexity of assembly configurations in SolidWorks. The discussion reflects varying levels of familiarity with SolidWorks among participants.

Hi,

Im designing an axial piston pump in solidworks, prior to analysis.

Basically I am having difficulty in getting the slipper pads from the top of the pistons to mate to the swashplate, so that when rotated the pump produces a pumping action.

I have the slipper pads connected to the pistons via ball joints, and in the piston assembley, the slipper pads rotate freely on the ball joint (i have used the ball head and a ball slot as the mating surfaces). However when i put the piston assembley into the whole pump assembley (with the piston assembley mated concentrically in the bore) the slipper pad no longer rotates freely on its ball joint, and as such i can't mate them to the variable angle swashplate.

Can anyone suggest a different mating arrangement which might help my problem?

Many Thanks

Ed

Ok, I've sorted the initial problem, however no it won't let me adjust the angle of the swashplate. Anyone have any ideas?

It's hard for me to visualize your problem. You would have more luck finding people who are familiar ith the terminology of your problem AND Solidworks, in the SW users forums. Have you tried there?
 
A picture of the assembly would help a lot.
 
I also have trouble visualizing what you're saying, but the trouble sounds like you're mixing mates from subassemblies with mates from higher assemblies. Are you using flexible subassemblies?
 
I have now sorted it out - it didnt like the sub assemblys being imported into the main assembly, and as such wouldn't mate as i required. I have also since discovered that for some reason i needed to arrange the mates in a very precise order - there all mated in now and looking tidy - only problem now is I am running pretty low on RAM.. but that's not an issue... its an excuse to go and buy more ram...

Thanks for all your help

Ed
