AI Thread Summary
The discussion focuses on finding a suitable plate for mounting a high-speed electric motor to a 30cm wheel, specifically one that can handle 700-800 RPMs. Regular lazy susan bearings are deemed inadequate for such speeds and loads, with suggestions leaning towards using go-kart wheels or bicycle bottom brackets for their better bearing capabilities. The user seeks a revolving swivel plate similar to a specific model linked in the discussion, emphasizing the need for a secure attachment to prevent shearing at the connection point. Additionally, there is a request for advice on the necessary adapters for the motor's 1/2" "D" shaped shaft to ensure proper integration with the wheel. A drawing will be provided later for further clarification of the setup.

A wheel from a go cart or similar would fill the bill. Any junkyards in your area?
 
I don't really know what you mean. I need a plate that can handle 700-800 RPMs. I already have the wheel, just need to find a way to mount it.
 
Car or go cart wheels usually come attached to a bearing that would serve your RPM requirements. You are quite right that a lazy susan bearing will not work for you.
The bottom bracket of a bicycle might work, the bearings are decent, although 700 rpm is several times more than they designed for as well. However, there is a through shaft, allowing for the motor and the wheel to be easily mounted.
 
We need a better description of what you are trying to achieve. A drawing is preferred.
 
I have a motor with a 1/2" shaft with a "D" shape. I am trying to drive a 30cm wheel with this motor. I need a revolving swivel plate like this - http://www.aliexpress.com/item/6-5-...re-hardware-barstool-turntable/550860671.html - that will hold the wheel. It needs to handle 700-800 RPMs. The motor shaft will go into the wheel on top and drive it.

I will post a drawing once I am off work. I need to know what kind of adapters I need for the shaft and wheel so the drive shaft doesn't shear the wheel at the point of attachment.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
