Design and Development of Reliable Integral Shaft Bearing for Water Pump in Automotive Engine to Reduce Assemble Time and Increase Production

Background/Objectives: The prime objective of this work is modifying of water pump which is used for cooling the engine in automotives. Methods/Statistical Analysis: In the existing pump ball, bearing is used in which the assembly and maintenance is difficult. In order to overcome these problems integral bearing is proposed. So it is planned to modify the existing pump to accommodate integral bearing with the purpose of reduce the assembly time and increase production. Findings:  The proposed integral shaft bearing has compact in size which is developed by eminence material and have one or two rows contains with balls as well as one row of roller. It has high reliability through a newly developed water resistant seal. This reliable bearing is three time better durability when comparing with existing ball bearing. It has high load durability, high resistant to heat load and water. Application/Improvements: The bearing with integral shaft has no inner rings, while having the raceway groove directly on the shaft.
