ANALYSIS AND OPTIMIZATION OF BALL BEARINGS FOR ROBOTS TO INCREASES EFFICIENCY, ALSO REDUCE STRESS
Main Article Content
Abstract
Bearing have important role in every rotating machinery system. Oneof the commonly used bearing typesis a ballbearing. The aim of this research focusesmainly on analysis and optimization of ball bearing for fatigue analysis & stress reduction by different optimization parameter. The optimization is done by analytical method and it is validatedby using ANSYS. The result of this research work is that by varying optimization parameter like contact angle,material & variation in number of ball increasesin fatigue life of bearing & reduction in contact stresses. The material optimization is done by changing materialof all bearing , generally steel material are used for inner race ,outer race , ball & retainer. By replacing the material ball by ceramic,inner race, outerrace & retainer by PEEK material. The life of bearing increased by increasing no of balls and by material optimization.
