A belt is a looped strip of flexible material used to mechanically link two or more rotating shafts. A belt drive offers smooth power transmission between shafts at a considerable distance. Belt drives are used as the source of motion to transfer power efficiently or t…

The following are the critical dimensions and geometries concerned with toothed gear: Pitch Circle : A pitch circle is an apparent circle in which two gears can be taken like smooth cylinders rolling without friction. Addendum Circle : The addendum circle is the …

Slow forward and quick return mechanisms are to be found on some metal cutting machines, digital printing machines and digital scanners. The output gives a slow forward linear motion followed by a quick return to the start position along the same path. Two of the most…

Comparisons between Flywheel and  Governors  are made in the following aspects: purpose, principle, application, and mechanism. S.no Flywheel Governors 1 Flywheel is provided on the engine and fabricating machines, viz., rolling mills, punching machines,…

A cam is a rotating or sliding piece in a mechanical linkage that drives a mating component known as a follower . From a functional viewpoint, a cam-and-follower arrangement is similar to the linkages. The cam accepts an input (rotary or linear) motion and imparts a r…

Watt linkage is also known as the parallel Linkage . James Watt invented Watt's mechanical Linkage. In Watt's Linkage, the central moving point is constrained to travel on an approximation to a straight line. Watt's Linkage can be found in some automobile …

Governor is a device used to maintain the speed of an engine within specified limits when the engine works in varying of different loads. Based on the source of controlling force, the governors can be classified into two types. They are centrifugal governors and inerti…
