The problem with a non-lubricated gear and roller is its risk of premature failure and endangered race geometry. The correct lubrication method can prevent such complications. Proper lubrication also lowers the risk of delaying and increases operating life. Luckily, there are solutions to this problem. Listed below are some of them: First, check the lubrication. In most cases, an excessive level can cause agitation loss and impairs the ability of gears to cool. A proper level can be found in Table 13.2, which gives a guideline. Check the level during operation as well as static levels. If the static level is too low, add more lubricant in the oil pan. Alternatively, consider using new high-performance lubricants. View here for more details on how to lubricate rollers and gears. Lubrication regime: Unlike a conventional gear oil, water-based lubricants tend to produce lower mean coefficients of friction than their mineral-oil counterparts. This is due to the fact that water-based equipment fluids are generally more effective than mineral oils with extreme-stress additives. However, high-viscosity lubricating substances are often too thin for some applications, which can result in metal-to-metal contact. Forced-oil lubrication: Using a forced oil circulating lubrication system involves installing an oil tank, a filter, and piping. This solution is suitable for high-speed gearing and large gear boxes. A circulating lubricant helps maintain the required viscosity and cleanliness of the lubricant. Proper lubrication prevents equipment failures. Keeping the oil reservoir well-lubricated is critical for the performance of gearboxes. It must be able to fight contamination and demulsify to remove water, which causes gear oil to sludge. LE has developed its own proprietary liquid additive called Duolec, which provides dual-acting anti-wear and extreme-pressure protection while imparting synergistic properties to the lubricant. These additives can reduce downtime and energy consumption. Check out the best rollers and bearings here. Pitting is the result of a loss of material. This happens when oil squeezes out of microcracks in the gear. Fortunately, these problems can be avoided with the right gear lubrication and operating conditions. However, if the gears and rollers have a surface hardness that is greater than the required tolerance, it is prone to overlapping large pits. If this happens, the gears will break down, causing a costly repair bill. The no-load losses of conventional gear oil and water-based gear fluids are similar, although the load-dependent losses are higher. Conventional gear oils and water-containing gear fluids both exhibit small losses at low pitch line velocities, while the no-load losses are large at high pitch line velocities. Water-based gear fluids show lower losses, particularly when compared to conventional gear oils. Another benefit of lubrication is that it is more compatible with plastic materials. Mineral-oil-based lubricants are not likely to attack plastics, and they offer excellent value for the dollar. But if you're looking for longer-term performance, synthetic lubricants are your best bet. While mineral-oil-based lubricants are compatible with plastic, synthetic oils are far superior. They offer long-term lubrication, aging resistance, and are compatible with most plastics. Check out this post that has expounded more on this topic: https://en.wikipedia.org/wiki/Gear.
