Non-lubricated gear and roller assemblies are often used in industrial applications that require high levels of torque and speed. They also reduce noise and provide a smoother operation. However, a lack of lubrication can lead to premature component failure and increase operating costs. Click for more info on non-lubricant from reliable professionals. There are several factors that influence the choice of a proper lubricant, including the viscosity of the oil and its compatibility with sealing materials. It is imperative that a proper lubricant be selected to ensure the longest service life possible. The correct viscosity grade should be selected based on the load sharing, pitch line velocity and lubrication regime. Choosing an oil with too low of a viscosity will cause boundary friction and result in heat, wear and failure. A lubricant's viscosity is determined by its ability to keep rolling elements and races separated from metal-to-metal contact. In addition, a properly chosen lubricant will help to minimize the amount of wear that occurs during the life cycle of a lubricated machine element. Micropitting and spalling are common problems with a lubricated gear and can be caused by a number of different factors. They include a rough or uneven surface on the tooth, poor lubrication, and abrasive conditions. The best way to prevent these problems is to select a lubricant with a low coefficient of friction, such as PAO or PAG-based oils. Abrasive wear is also a problem that can occur in a lubricated gear and is usually caused by hard particles in the oil gouging the gear teeth. A lubricant with an EP additive is recommended to help avoid this problem. Destructive pitting is another common issue that can arise in a lubricated gear and can also be caused by poor lubrication. This condition can be prevented by selecting a lubricant with a lower coefficient of friction and operating under suitable conditions. Generally speaking, there are two primary types of friction in lubricated and non-lubricated gear and roller contacts: fluid and solid. The relative amounts of each vary based on the load-sharing conditions, lubrication regime, and the type of lubricant used. In addition to the basic lubrication characteristics, a lubricant should be compatible with seal material and provide adequate wear protection. A lubricant that does not conform to these requirements can lead to leakage or lubricant starvation, which could cause serious damage to the machinery. The use of an appropriate lubricant can also protect the gear from other mechanical stresses that can shorten the service life of the gear and reduce efficiency. In addition, a lubricant that is properly formulated can reduce the likelihood of corrosion, erosion and cracking. To get more expounded on the subject, click here! The most important thing to remember when selecting a lubricant is that it needs to be clean and free of contaminants. If the lubricant is not clean enough, it can lead to fouling of the tribosurface, which in turn can limit its ability to keep the components separated from each other. In addition, a dirty lubricant can cause the oil to thicken and become too heavy for the components. This can also result in the lubricant being too thick to emulsify with water, which can also reduce its effectiveness.
