The Auxiliary Belt drive system (ABDS) should not be confused with the Timing Belt drive system (Synchronous Belt Drive System -SBDS) of the internal combustion engine. Timing Belt drive takes power from the crankshaft and drives the camshaft/s that in turn drives the inlet and outlet valves of the engine. On the other hand, an

What is Grease? Grease composition can be assumed like a sponge with fluid absorbed inside. In place of a sponge, the thickener is there that holds the base oil and additives. The base oil and additives are the major components in grease formulations and have a considerable influence on the performance of the grease in

Importance of Gearbox in a Machine Gearboxes are devices for the transmission or translation of movement. In industry, gearboxes are used to transform the speeds and torques produced by the prime mover in order that they are appropriate to the machine which is to be driven. The speeds and torques required by the machine are

What is a Coordinate Measuring Machine? In this modern and fast-changing industrial market with Industry 4.0 coming in, Flexibility and Automation are two of the most important market requirements in Industrial Metrology. The trend of automation is closely linked to increasing throughput. This requires taking and recording the whole measurement process into consideration. Automated part
What is Hertzian Stress? The area of contact, when two curved surfaces are in contact, is theoretically zero, so this will cause infinite stress and immediate failure of the object. However, on the application of load, a real area of contact is formed due to the deformation of the mating surfaces. Thus, when two bodies
