Disadvantages of Non-Lubricated Gear and Roller Systems

 

While conventional lubrication methods are effective for some applications, they are not a viable alternative in some circumstances. Non-lubricated gears and rollers have many disadvantages. Their reduced reliability, high friction, and endangered race geometry make them less reliable. In some cases, the gears themselves are not lubricated at all, resulting in a loss of computer worth. Other disadvantages of non-lubricated gears include excessive noise, metal-to-metal contact, and increased maintenance costs.

 

In some cases, the non-lubricated gear and roller may also experience abrasive wear and degrade sooner than expected. This condition can be exacerbated by high operating temperatures and particulate contaminants. On this website https://www.intechpower.com/product-types/rollers-and-bearings you will learn that proper lubrication will prevent metal-to-metal contact and prolong the gear's life. If you suspect that your gears and rollers need replacement, you should check the part number and part description.

 

A gear-and-roller combination may be contaminated with dirt, water, or other substances, making the lubricant ineffective. A lubricant that remains thermally stable will prolong the gear's lubrication life and extend drain intervals. Furthermore, gear oil must resist oxidation, which can reduce its life by half for every ten-degree increase in temperature. Some enclosed gearbox applications are exposed to high heat and heavy loads, while industrial gearboxes require the gear to operate in harsh environments with dirty and contaminated conditions.

 

Grease is an ideal choice for low-speed applications with low loads. However, grease has its disadvantages and should be reapplied periodically. Grease can become excessive and endanger gear teeth. Besides, grease does not have the desired cooling effect. Too much grease can cause agitation, viscous drag, and power loss. A splash lubrication method requires three meters of tangential speed. Spill lubrication can cause a number of problems, including temperature limitation and oil level.

 

Oil lubrication is a critical aspect in non-lubricated gear and roller systems. Without lubrication, the cage and rollers may suffer from increased friction. Grease is most effective in open gears, but insufficient lubrication can negatively affect the race geometry. As a result, grease washes out from bearing areas and compromises the race geometry. However, the results were not atypical.

 

The oil level of the gearbox is crucial to its performance. To ensure proper lubrication, the speed reducer part number and mounting position are necessary. The level of oil should be near the centerline of both gearboxes. The oil drain port and the oil level port should be plugged from the factory to define the recommended oil level in the gearboxes. Ensure the oil level in the lower gearbox is at least 90% before installation.

 

Another important factor in gear oil is its ability to fight contamination and demulsify water. Duolec, LE's proprietary liquid additive, is one solution for this problem. This additive imparts synergistic properties to the lubricant, reducing the wear and downtime of the gears and rollers. Ultimately, it also helps to reduce the energy bill. This solution is effective for a wide variety of applications.
