One of the most efficient methods for mechanical power is geared drive. Starting simple spoke gears made out of strong wood in the pagan era, this system has evolved to its present state, over the past several centuries of industrialisation. Sophistication, innovation and design or manufacturing concepts for any product move hand in hand. Ultra modern gear technology has made it possible to achieve the highest possible percentage of positive mechanical energy transmission required for all plant and machinery manufactured around the globe. Innovative materials, gear profiles, angle of contact and other specifications have ensured minimum power loss, lowest noise emission and reduced wear in gears.

Consequently, the production processes have transitioned to use of highly precise gear generation techniques, which deliver burr-free, fully polished and finished gears, shining like glass! Another significant development in gear technology is directed towards miniaturisation to accommodate smaller high-speed gearboxes and drives delivering the same amount of power as before, more so in the automotive and engine applications.

India is fast joining the club of world leaders in gear manufacturing. Over a hundred new manufacturers have developed during the past decade. They cater to a variety of machine tools, construction equipment, automotive, white line and household appliances and many other applications. Their good reputation extends beyond our national waters as they find tremendous acceptance in the overseas markets. EQUIPMENT INDIA brings forth a round up of some well known players in this field, for the interest of our readers.

Destined to be the third-largest manufacturing hub in the world, India beckons young and aspiring entrepreneurs to come forward and carry this development to the next generations.

On the maintenance front, we present an authored feature on hydrostatic systems. Major power amplification and jerk-free power transmission is achieved through hydrostatic components immersed in hydraulic oil under pressure. Usually it comprises a closed-loop hydraulic system. Since oil contamination is the single biggest factor contributing to a gross deterioration of hydrostatic efficiency and preservation of the various elements of the system, the section provides a detailed guidance on how to maintain the same to the required standards. It expounds on the methods to control or avoid oil contamination by adopting the best maintenance practices.
