Gear reducers can be complex devices that apply the science of gearing and mechanical benefit to perform thousands of complex functions 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 advisable to understand how to restoration the failed products and preventing future failures in order to keep production up and running.

Three things that may cause premature failure are poor lubrication, misalignment and overloading. Failure modes can involve bearing failures or gear failures, or both.
Lubrication is crucial for both bearing and equipment life. Important areas of lubrication are the level of lubricant that is delivered to each gear mesh and bearings, as well as the properties of the lubricant. The lubricant forms a thin film that stops metal-to-metal get in touch with between gears and between bearing components. Modern industrial gears make use of an involute tooth type and tooth engagement, which is a mixture of rolling and sliding. The essential oil film is certainly a thin barrier between moving parts which allows the rotating force to turn the gears quickly without damage to the metal areas. Contamination in the lubricant can result in scuffing and far faster wear for both bearings and the gearing in a gearbox, so that it is essential that maintenance mechanics check gearbox lubricant for contamination periodically, once for season as a minimum. Each gearbox could have a recommended oil level as well as a gear reducer box method to lubricate both the bearings and the apparatus established. With bath lubrication, all moving components dip down below the oil level. With splash lubrication, essential oil can be splashed around inside the gearbox housing by fast moving elements, covering all moving parts. With pressure lubrication, oil is definitely pumped to each gear mesh and bearing through spray nozzles or essential oil passages from the gearbox essential oil sump or from and exterior reservoir.
