Mechanical Power Transmission topics include: Belt drive, chain and sprocket drive, gear drive, bolts, nuts, washers, screws and rivets. Mechanical power transmission is the process of transferring energy from one place to another using mechanical components. This method uses mechanical components instead of electrical methods to direct power from a source, such as an engine or motor, to an output device.  Mechanical power transmission provides control over the speed, torque, and directionality of the conveyed force. It can be used in a variety of applications, including: Rail transit... Show more
