I just had a customer looking to put a custom shaft on his dynamixel xl-430.
Do you have any kind of information about doing this? Or is this something you don't recommend? He is looking to put a 1/4" or 8mm shaft on it.
It is difficult to confirm whether the additional shaft would be feasible or not without knowing the design.
However, if the customer is trying to extend the output shaft so that she/he can rotate some hardware from a distance from Dynamixel, I'd recommend to use flexible shaft coupler in order to prevent damage on each component.
Also, try not to apply too much radial load(I'd say about 15N though this is not an official value) on the extended shaft.
Thank you for your response.
I will let the customer know.
The customer has replied.
"All I am trying to do is connect an an cylindrical shaft with diameter 8mm to the XL-430. I have some flexible shaft coupler but is there anyway to connect them to dynamixel XL-430 ? If there is such a horn or something, we would like to buy it. We had a connector for regular servos with the sawy mount but I am not sure it would work for this guy."
Looks like he trying to connect the shaft directly and trying to find a horn as well. Is this possible and is there any such horn that would fit?
Unfortunately we do not sell parts for customization, and it is solely customer's responsibility to find or make necessary parts for modification.
Again, it is difficult to say which method will work or not without knowing the hardware configuration.
If the "cylindrical shaft" is not perfectly aligned, it could cause unnecessary friction or load on the hardware and could also cause excessive worn out of the internal gear of Dynamixel.
I think it would be very helpful for the customer to talk to someone who has mechanical background.
This is my personal opinion, and if I were just modifying the product for my personal project or just for fun, I'd just connect the shaft without having too much worry about breaking some parts or energy efficiency.
But I don't have any background knowledge about the customer's application, so I can't officially recommend this to your valuable customers.
I hope you understand about this.
Thank you :)
Thank you very much for your response.
I totally understand and essentially it is him that needs to do it in the end.
Depending on what he needs we can get a horn made for him.
But customization is always tricky and you really need to know what you are doing.
