Gears are probably among the most loaded components in any mechanical system. They are used to transmit force at different angles, increase/decrease speed and improve the mechanical advantage of the transmission. Although the transmitted load is usually within established safety limits, it is possible that the gear loads are higher than originally intended.
The term “heavy load” is relative but can be applied to most low-speed gearboxes that move large equipment (long conveyors, large extruders, etc.) or force solid materials through molds or extruders. Of course, this doesn’t apply to all gearboxes, but these are certainly the more heavily loaded ones. To better understand this issue, Unioil Lubricant invites you to follow the article below!
1. Understanding lubricants for extreme pressure industrial gears
Extreme pressure industrial gear oils are lubricants manufactured from highly refined base oils blended with anti-wear, extreme pressure, demulsifying, and anti-foam additives. Properties such as pressure resistance, wear resistance, corrosion resistance, impact resistance, anti-foaming, dispersion, viscosity improvement, etc. are all created and enhanced by additives. Not all additives are used for extreme pressure industrial gear oils.
Usually the formulation for each type of oil, for each type of machine, is different and optimized by the oil manufacturers. But regardless of the characteristics of the oil, the additive must comply with the following criteria:
- Easily soluble in oil,
- Does not affect the emulsifying effect of the oil,
- Non-corrosive to metals,
- Not easy to evaporate under working conditions…
Extreme pressure industrial gear oil has the main effect of lubricating gear positions, extreme pressure gearboxes used in gear reducers, gearboxes… with outstanding characteristics of pressure resistance, impact load and impact resistance. anti-foam.
2. Why use heavy duty gearbox gear oil
Gear systems not operating at their specified speed or power can also increase the load on the gear surface.
For example, imagine you have a motor coupled to a gearbox, which is then combined with a stirrer to stir the mixture inside the tank. The gearbox is selected for a certain torque and to handle a certain amount of resistance from the propeller moving through the mixture. If you remove the original stirrer and replace it with a larger one without replacing the gearbox, this will increase the load on the gears and can subsequently cause increased friction and eventually gearbox failure. .
Note that the oil selected for the gearbox is very important for the life and performance of the gears.
As the load increases, so should the viscosity of the lubricant being used, regardless of whether it is oil or grease.
The use of additional additives, such as extreme pressure (EP) additives, or solid additives, such as molybdenum disulfide or borate is necessary to help support gears under load.
Another disadvantage of a higher-load transmission is the strain it puts on the transmission, not only will the transmission now take more load, but the motor that is responsible for turning the gears will also be under heavy load. This puts more strain on the engine, causing it to run hotter, use up more energy, and ultimately fail sooner. Therefore, the use of lubricants designed to withstand heavy loads will greatly help in minimizing damage to the gears and the engine associated with it.
So while gears are designed to take more load than what’s specified, it’s a delicate balancing act to ensure you have the right lubricant and the right transmission components. This can make the difference between a machine running at peak performance and a machine struggling to meet the system’s demands.
