Gear reducers could be complex devices that apply the science of gearing and mechanical advantage to run thousands of complex operations in many different industries. Gearbox manufacturers have designed a variety of gearboxes in multitudes of different configurations and equipment ratios. When failures happen it is critical to understand how to restoration the failed systems and preventing future failures to keep production up and running.
Three things that can cause premature failing are poor lubrication, misalignment and overloading. Failure settings can involve bearing failures or equipment failures, or both.
Lubrication is critical for both bearing and gear life. Important areas of lubrication are the level of gear reducer box lubricant that is usually delivered to each equipment mesh and bearings, as well as the properties of the lubricant. The lubricant forms a slim film that stops metal-to-metal contact between gears and between bearing parts. Modern industrial gears make use of an involute tooth form and tooth engagement, which really is a combination of rolling and sliding. The oil film is usually a slim barrier between moving parts that allows the rotating push to turn the gears very easily without damage to the metal areas. Contamination in the lubricant can result in scuffing and much faster use for both the bearings and the gearing in a gearbox, so it is essential that maintenance mechanics examine gearbox lubricant for contamination periodically, once for yr as the very least. Each gearbox could have a recommended oil level in addition to a method to lubricate both the bearings and the apparatus set. With bath lubrication, all shifting components dip listed below the oil level. With splash lubrication, oil is usually splashed around inside the gearbox casing by fast moving components, covering all shifting parts. With pressure lubrication, oil can be pumped to each equipment mesh and bearing through spray nozzles or oil passages from the gearbox essential oil sump or from and external reservoir.
