Abstract
Globoidal cam protractor is usually applied in pharmacy,electron,printing and so on. It has compact structure and high positioning accuracy.Globoidal cam protractor can be configured big quantity rollers(at most sixty).It not only has steady dynamic performance,but also has reliable motion.
In the response to the demand of Electromechanical General Factory,doing the development of the globoidal cam protractor.
Firstly,according to the theoretical formular of the globoida..
