Modeleing a ball beasring assembly
Modeleing a ball beasring assembly
(OP)
Does anyone have some tips and techniques for modeling a ball bearing assembly? One of our engineers did one, but it is failing when we reopen the assembly file. The assembly constraints are being lost. If we freeze the assembly, the balls are not in the right location with the races.

Again, I'm no expert. You've probably tried this. But, I hope something in here was helpful.

Here is exemple

Wildfire is very nice, if you know,
how work with him
RE: Modeleing a ball beasring assembly
Part 1
1. Model the center raceway section using a revolve feature (creates axis).
2. place a datum point in the raceway on the same dia path of the center of the balls.
3. Pattern the datum point around the center axis of the raceway (each point is another ball).
Part 2
1. Model the ball and place a datum point in the middle.
Part 3
1. Model the outter raceway using a revolve feature.
Assy
1. Place part 1 (center raceway)
2. Place the first ball (part 2) and constrain the datum point in the middle to your first datum point in the circular pattern for the center raceway.
3. Referance pattern the ball to the datum point circular pattern in the center raceway.
4. Place and constrain part 3 (outter raceway) to part 1 (inner raceway). I recommend align center planes and insert (2 constraints)
Please look at the attached assy if you like for a better understanding.

That said, you can assemble the ball(s) and convert each one to "fixed". After all, there is nothing particularly parametric about the location of the balls within the races.
