Hi. I am trying to create an ice cream mixer where the motor is like (believe its called a planetary gear?)
Its basically 1 motor/gear that spins but at the same time that gear also goes around 360degres.
Any suggestion how i could do this?
The total width of these small tubs is about 8cm across.
Ps. I would just use a kitchen aid mixer but the radius it spins around is way too large. Wont stay within the tub!
Regards
A planetary gear is the following: en.wikipedia.org/wiki/Epicyclic_gearing
This type of gearing is normally more efficient than spur gears, and is used to reduce the RPM of a motor and increase the output torque.
Can you perhaps provide a drawing of what you are looking to do?
Thanks for ur response. My drawings r rubbish but the spindle i have marked as 1 needs to rotate…at the same time number 2 must also rotate so that it mixes the ingredients really well.
Thanks for the image and we think we understand better.
You essentially want this motion, correct? youtube.com/watch?v=VA_Uiu_yfhg
If so, you need your main shaft needs to be in two parts - one part which is fixed to a gear and does not rotate, while the other spins.
The part which spins is connected to an “arm” which has a gear mounted at the end which meshes with the gear above.
As the shaft spins, the arm rotates, and as the arm rotates, the outer gear meshes with the fixed gear, causing it to rotate.
You would choose the gears based on the radius you need, as well as the torque.
Yes exactly what i need!! Radius of my cup is about 6cm. How much will it cost pls?
We don’t sell that mechanical setup, nor do we offer design services, so your best bet is to choose a pair of gears, the motor and hubs and custom-make the frame using wood / metal or 3D printed plastic.

You’ll also need a shaft within another shaft.
Rather than gears, you can use a timing belt or a sprocket and chain system.
If it’s just “one-off” and you don’t mind that it is a bit hobby-grade, you can consider using VEX or Tamiya products:

Ok thanks. Id love to try and make it but dont think il be able too…would u be able to send me a list of parts i need and i might try give it a go
If you try Tamiya products for an inexpensive proof of concept, the following may be of interest:
Mounting plate: robotshop.com/en/tamiya-univ … =RB-Tam-54
Shafts: robotshop.com/en/tamiya-3mm- … =RB-Tam-51
Pulley Set: www.robotshop.com/en/tamiya-puley-set-s … =RB-Tam-45
Arm set: robotshop.com/en/tamiya-univ … =RB-Tam-47
Variable motor: robotshop.com/en/tamiya-high … =RB-Tam-20 (many motor options and gear ratios available)
You’ll also need a hollow shaft (3mm bore) which fits over the standard 3mm Tamiya shafts.
