Calistral and Boltimor (1989), comment that service of gear couplings can be achieved by understanding the principle of wear, how lubricants functions and proper maintenance.proper lubricant selection greatly increase the life of gear couplings,Once proper installed periodic lubrication is the only maintenance required..In other to select proper lubricant, the principle of gear wear and lubricant properties must be understood. Maintenance is assume in disadvantage of gear couplings,,they are popular because of the proper reasoning and the principal reasons are: Gear coupling are forgiving, even when improperly installed or mishandled, It continue to perform than most other types of couplings and gear coupling are reliable and safe.Their main cause of failure is teeth wear,which is a gradual rather than abrupt. Even when the teeth wear out completely,the only effect is its loose of power without coupling flying apart. Coupling in general can be divided into low and standard and high speed or high performance coupling.Maintenance requirement, if the two types are very different.The article will describe maintenance of the standard type.
An objective in many maintenance operations is to improve condition through more effective performance.of maintenance work. Although this be worthwhile, it should first be established that the work being done is necessary.The reduction effective maintenance can bring about in the need for maintenance work can in many cases significantly improve both the output of the manufacturing facility and the unit cost of the product in addition to reducing the maintenance cost (Fast,1920).
