Summary:The cycle of induction motor disassembly inspections depends on the durability of the grease, which is the least durable of all the bearing parts and materials used at present. It is therefore highly desirable to extend grease service life. To meet such requirements, a number of studies were made into grease pocket structures, which concluded that an improvement in structure was essential as grease pocket shapes have a direct relationship on grease lubrication effectiveness. A laboratory test under static conditions was performed with small grease pocket models of different shapes to formulate a grease pocket design guideline.
