Notes:

This flexible shaft coupling is to be used to attach the motor group prototype of the ergoCub joint to the brake test bench for testing the motors. Thus I would like to add it to our library.

Checklist:

Complete the checklist in order to proceed with the request.

@divyashah can you double check the alias? I can not find the product CPLCN32-9_525-RDC14-B: image

@divyashah can you double check the alias? I can not find the product CPLCN32-9_525-RDC14-B:

The MISUMI product code is CPLCN32-9.525-RDC14 as in the title of this issue. Product is also linked in the description.

I then named the Creo part as MISUMI_CPLCN32-9_525-RDC14-B.prt, based on the part name of the source CAD file. Let me know if this part name is ok, or I should update it ?? cc @fiorisi

Ok I see. Probably for codes that contain a . we can decide to replace it with _.

In this case I would add few lines in the guidelines.

Yes, I will update the guidelines accordingly.

Adding another variant for this flexible shaft coupling to this issue. So we have the following two variants with a difference in internal diameter on one side:

Relating to the mass properties, there is no specific mass mentioned in the product documentation. However, the CREO files (attached in the issue description) have mass properties defined in them. I then assigned the same density to the CREO part to be added in our cad-libraries.

Once we have the physical component, we can measure the weight and then verify the mass properties.

@divyashah you can check the Catalogue tab. image

Here probably you can find also the mass. image

divyashah commented 3 years ago

Thanks @fiorisi!

I checked the catalogue and the mass shown for the CPLCN32 series is 64 g. image

I now assigned the calculated density to the components accordingly.

With the last commit, I added the corresponding files to our library.

@divyashah , if the files are ok, we can close the issue.

@divyashah , if the files are ok, we can close the issue.

Yes, closing the issue.
