Mechanical Power Transmission :Electrical power transmission has replaced mechanical power transmission everywhere except very shortest distances. What is worth remembering, however, is that from the 16th century through the industrial revolution to the end of the 19th century mechanical power transmission was the norm – even for long distances. The oldest long-distance power transmission technology involved systems of push-rods connecting waterwheels to distant mine-drainage and brine-well pumps. This technology survived into the 21st century in a handful of oilfields in the US, transmitting power from a central pumping engine to the numerous pump-jacks in the oil field.

Mechanical Power Transmission
Importance of pulleys
•Manufactured according to relevant standards to help ensure optimum performance
•Equipped with taper bushes for quick and accurate installation
Taper bushes provide an economical, easy, and efficient method of securing sprocket, pulleys and couplings to a wide range of standard metric and imperial dimensioned shafts of general commercial tolerances and finish. The taper surfaces on the bush and mating hub are driven together by high tensile screws, causing the split bush to be firmly contracted onto the shaft. The strong clamping force enables transmission of high torque.
