Gear reducers can be complex machines that apply the science of gearing and mechanical advantage to run thousands of complex operations in lots of different industries. Gearbox producers have designed a number of gearboxes in multitudes of different configurations and gear ratios. When failures happen it is advisable to understand how to restoration the failed units and how to prevent future failures in order to keep production ready to go.

Three things that can cause premature failure are poor lubrication, misalignment and overloading. Failure settings can involve bearing failures or gear failures, or both.
Lubrication is critical for both bearing and equipment life. Important aspects of lubrication are the volume of lubricant that is delivered to each gear mesh and bearings, along with the properties of the lubricant. The lubricant forms a thin film that prevents metal-to-metal get in touch with between gears and between bearing parts. Modern industrial gears use an involute tooth type and tooth engagement, which really is a combination of rolling and sliding. The essential oil film is a slim barrier between shifting parts that allows the rotating force to turn the gears easily without damage to the metal surfaces. Contamination in the lubricant can lead to scuffing and much gear reducer box faster put on for both bearings and the gearing in a gearbox, so that it is essential that maintenance mechanics verify gearbox lubricant for contamination periodically, once for 12 months as the very least. Each gearbox could have a recommended essential oil level as well as a technique to lubricate both bearings and the apparatus set. With bath lubrication, all shifting components dip listed below the essential oil level. With splash lubrication, essential oil is usually splashed around within the gearbox housing by fast moving parts, covering all moving parts. With pressure lubrication, oil is pumped to each gear mesh and bearing through spray nozzles or essential oil passages from the gearbox oil sump or from and external reservoir.
