what are the parts of a wheel
The main difference between wheel and rim is that rim is not the whole wheel but only a part of the wheel. Key parts of the wheel are rim and disc. The hub may be also considered as a part of the wheel. The hub is wheel base with studs on which the wheel is attached to the suspension. The rim is a cylindrical wheel outer edge holding the tire on the wheel. Main function of the rim is supporting and sealing the tire to the wheel.

Fly Wheel - The wheel that rotates when treadling and causes the other various parts to operate. B. Drive Band - A cord that goes around the fly wheel and the flyer whorl. C. Flyer - A U-shaped piece of wood with hooks lined up on one or both arms. The hooks are used to store the yarn evenly on the bobbin.
