Gear reducers can be complex machines that apply the science of gearing and mechanical advantage to run thousands of complex operations in many different industries. Gearbox manufacturers have designed a number of gearboxes in multitudes of different configurations and gear ratios. When failures happen it is critical to understand how to repair the failed models and how to prevent future failures in order to keep production ready to go.
Three things that can cause premature failing 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 definitely delivered to each equipment mesh and bearings, as well as the properties of the lubricant. The lubricant forms a thin film that prevents metal-to-metal contact gear reducer box between gears and between bearing parts. Modern industrial gears make use of an involute tooth type and tooth engagement, which really is a mixture of rolling and sliding. The essential oil film is certainly a thin barrier between shifting parts that allows the rotating pressure to turn the gears very easily without damage to the metal areas. Contamination in the lubricant can lead to scuffing and far faster use for both bearings and the gearing in a gearbox, so it is imperative that maintenance mechanics examine gearbox lubricant for contamination periodically, once for calendar year as the very least. Each gearbox would have a recommended oil level as well as a technique to lubricate both bearings and the apparatus established. With bath lubrication, all moving components dip down below the oil level. With splash lubrication, essential oil is definitely splashed around within the gearbox casing by fast moving parts, covering all moving parts. With pressure lubrication, oil is usually pumped to each equipment mesh and bearing through spray nozzles or oil passages from the gearbox oil sump or from and external reservoir.
