This article gives a short introduction to the main European standards for railway wheel bearings – the EN (European Norm). Railway operation is safety critical. Railway wheel bearings are one of the most critical machine elements for the safe and efficient operation of trains. A broken, overheated, or blocked wheel bearing can lead to stopping

Drive System of a Railway Locomotive All modern Electric & Diesel locomotives are hauled by traction motors. An electric locomotive is powered by electricity from overhead high-tension (voltage) electric lines through pantographs and transformers. In contrast, diesel locomotive has Traction Alternator connected to the engine & electricity generated by the alternator is used to power

What is a compressor? As we know liquids are incompressible (theoretically) whereas gases or air can be compressed to a desired pressure (above atmospheric pressure). Practically, Gases can not be used for engineering purposes (such as in industrial pneumatic systems, blowers, household gas supply for heating, hospital oxygen supply systems, air-conditioning, etc.) at atmospheric pressure.

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
