How to design a Groove

Builder

Dear all,

 

I want to design a mechanism with two rotational part. The first one is rotating with constant speed. The second one is a disc with 8 bearings that each one goes through a groove inside the first part. What is the best and most accurate way to model the shape of groove so that the bearings could go through the groove without any interference?

 

I will then solve this assembly in Simcenter Motion Simulation

The assembly and also stp file is attached bellow

 

Thank you in advance

Hello, @Sina 

 

I can't open the .RAR file and can't find the .STP file. Are you driving the width and height of the groove by the diameter and height(+clearance) of the bearings?

@Sina Would not a more direct method be to create a helix with the pitch as pi*PinDia/8?
