A flange is an external or internal ridge, or rim (lip), for strength or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc. The term "flange" is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.
Hubs are used to transmit mechanical power from a drive motor by coupling it to an output device such as a wheel or an arm. Hubs are generally centered joining points and may be implemented singularly or in tandem operation.
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave.
