May 27, 2021 · A crankshaft is an essential part of the power transmission system. In which, the reciprocating movement of the piston is converted into a rotating movement by using the connecting rod. A crankshaft consists of crankpins, crank webs (crank arms or cheeks), balancing weights, and main journals.

The cranking motor mounting must always be tight and the drive must be in good condition. The condition of the drive can be established by operating the cranking motor two or three times and noting the action of the drive. The cranking motor must be removed if the drive is to be actually seen and exam-ined. On overrunning clutch type crank-
In reciprocating pumps or compressors, the purpose of the crankshaft is to convert rotary motion from an electric motor or other prime mover into the reciprocating motion used to reciprocate the piston. The crankshafts start rotating with the starting of the motor.
It has to spin, plunge, accelerate and decelerate, twist and untwist hundreds of times a minute, depending on its application. We’ll cover the highlights of crankshaft design and then we’ll discuss all the things you need to check before you load it in the block for the first time.
