Gearbox forms an important component in many industrial applications as they are used to change the standard speed factor of electric motors. Hence, ensuring their optimum working efficiency is a vital necessity and for this its lubrication system becomes a crucial factor.

The relation of lubricating oil to a gearbox is as fundamental as water is to a fish. In fact, it can be called the blood system of the gear box. If the levels of lubricating oil fall too low and are unable to perform the function of lubrication, then the gearbox is bound to fail. Failure of the gearbox’s working can lead to many increasing costs. Besides the costs of repair and replacement, the costs of lost production will run into huge amounts.

Consequences of low levels of lubricant

If the lubricant film is in less quantities on the gear wheel teeth, it can result in surface fatigue. This occurs as the surfaces are not adequately safeguarded from the stress leading to formation of pitting in the contact region. We being theauthorised dealers of Greaves gearboxes do not fail to emphasize this aspect to the customer. Another problem that can arise if the film of lubricating oil is not maintained is scuffing. The incidence of increased temperatures cause wear and distress of the material surface.

Lubricating oils performs three basic functions:

• Provide surface-wear protection
• Safeguard metal surfaces from corrosion
• Cool the internals of the gearbox

In fact, an important aspect of preventive maintenance is the regular checking of oil levels and replenishing the same if they have fallen to low levels. Additionally, it is also checked to ensure that the lubricating oil has not lost its ability to lubricate and that it is not contaminated with any metal particles.

Importance of selecting right lubricant

While selecting the right oil for lubricating your gearbox, it is necessary to understand itsprojectedlife, the seals and the required performance of the gearbox in the concerned application. S.C. Industrial Syndicate being the largest gearbox dealers in Mumbai pay maximum attention to this aspect. Depending upon the size and style of the gearbox, various methods are employed to roll the lubricant over the bearings and gears; some of the most popularly used being Splash lubrication, Pressure lubrication or Mist lubrication. Whatever be the type or method used the importance of choosing the right one cannot be denied.

In almost all cases, most of the lubrication problems that occur in a gearbox are on account of wrong choice of the lubrication oils. This leads to a drastic reduction in the life of a lubricant and consequently the life of the gearbox. A suitable lubricating oil helps in providing greater gearbox reliability, transmission of slip-free power at higher mechanical efficiencies, low maintenance and longer life of the gearbox. It is therefore essential that the right choice is made with guidance from us,authorised dealers of Premium gearboxes.

All industries demand greater power from various sized packages of Greaves gearboxes. Lubricant manufacturers are engaged in addressing this need by introducing superior lubricating oils to carry increased loads reliably. At the same time it is the responsibility of the users to consult authorised distributors of Greaves gearboxes and incorporate the right type and amounts of lubricating oils so that your gearbox keeps running for a long time.
