While there are advantages to both methods of lubrication, the non-lubricated gear and roller system is a better choice for many applications. Besides being easy to maintain, non-lubricated gears and rollers also operate quietly. They are also easier to maintain without the need for oil bathrooms. Metal-to-metal helical gearing is the typical gear drive for rolling mills. However, the disadvantage of oil bath lubrication is that it is highly inefficient and can cause gear contamination. Moreover, invested oil is toxic and can be wasted.

 

Intech Corp., a company that manufactures plastic-metal composite gears, discussed how the self-lubricating plastic gears can be used in such applications. Mihov outlined the application's unique requirements, which included space limitations, a high torque and reversing torque. In addition, the self-lubricating plastic gears could be retrofitted to existing equipment. It is a good alternative to steel gears.

The results of DoD lubrication experiments at FZG's gear efficiency test rig have been promising. The results of the experiments at the FZG gear efficiency test rig are summarized in Figure 12. The measured failure torques were calculated as Hertzian stress at pitch factor. These failure torques vary in different speeds and depend on the life span of the product and the seal. Thus, proper lubrication is essential for the longevity of non-lubricated gears and rollers.

 

A non-lubricated gear and roller is subject to high wear and friction. It can be damaged if it is subjected to excessive friction. To protect it from these risks, the bearing is an essential gearbox component. Its proper lubrication also protects its bearings, thereby reducing delaying and prolonging its lifespan. This type of lubrication is also recommended for gearboxes that are used in industrial settings.

 

The input shaft bearing was also affected by excessive wear. A 0.015-inch-deep groove was observed. The inner race also had similar results. The cage was also excessively worn, with fractures in several locations. The small inner-race diameter compromised the separation of the rollers. Ultimately, the lubrication-related failure was determined. This failure was the result of inadequate lubrication. Once again, the failure of lubrication made the gearbox irreparable.

In contrast to non-lubricated gear and roller systems, the forced oil filtration system requires a system for applying lubricant to the gear and roller surfaces. This system involves a pump, an oil tank, and piping. A forced oil lubrication system is only suitable for large gear boxes or high-speed gearing. Because a circulating lubricant is clean and has a consistent viscosity, the oil film is necessary to minimize friction and prevent dry metal-to-metal contact.

 

In addition to the above benefits, grease is poor at cooling and may raise the temperature of the device when loaded. The amount of grease should be appropriate to avoid the excessive heat produced by the gear. Using too much grease can cause agitation, viscous drag, and power loss. Splash lubrication is another option. It is used when the system is enclosed and requires a minimum of three meters/s tangential speed. However, this method has some drawbacks, including oil level and temperature limitation. Check out this post https://en.wikipedia.org/wiki/Lubricant for more information about this topic.
