Abstract
Belt conveyor has the strong adapt ability and it uses widely in convey machinery. Roller is one of the key components in the belt conveyor; it plays an important role in the normal operation of belt conveyor. In order to study the influence factors of roller service life, this paper analyzed the movement of the roller and used Solid edge ST4 and ADAMS software to establish the virtual prototype model of roller and kinematics simulation of the model. This paper concludes the main factors affect the life are the sealing effect, poor alignment of the roller and the alignment of the bearing. Through the analysis of roller can reduce the design errors, improve the processing and installation accuracy mostly at the same time in the production process, it also can reduce the design and process time significantly and lower manufacturing cost and prolong the service life of roller.
