Symptoms of Non-Lubricated Gear and Roller

The performance of a non-lubricated gear or roller is inferior to its lubricated counterpart. The lubrication scheme must be carefully considered before making modifications to the gear or roller. For example, a gear may be lubricated with a water-containing equipment fluid, while another might use a mineral oil with an extreme stress additive. However, water-based lubrication is not suitable for all applications, as the thickness of the lubricant is insufficient to protect the gear from metal-to-metal contact.

When the gear or roller is non-lubricated, it may exhibit a number of distress symptoms. These include abrasive wear caused by a breakdown of the oil film. This damage is further exacerbated by particulate contamination in the oil. Eventually, gears with poor lubrication will degrade, resulting in significant damage to the roller and pinion.

Micropitting is another problem that can occur. In heavily loaded gears, oil squeezes out of microcracks and causes a pit. The pitted surface appears gray or white, depending on the surface roughness of the gear and operating conditions. This pitting will eventually lead to gear failure.

Corrosive wear is a result of abrasive materials in the gear oil and moisture. Other causes include foreign materials and extreme pressure additives. These substances will react with the teeth and cause them to lose their effectiveness. Another common type of failure is breakage, in which the teeth are broken. This can damage other components, such as bearings and shafts. The teeth must also be properly aligned to prevent breakage.
