The quality of mechanical drive decides the performance of the servo system , the driving error and hysterisis error are the most important precision index
3.
Precision indexing : taking seiki special design of the cam rollers for segmentation , can maintain a higher degree of precision segmentation and high torque , to ensure the re - load capability
4.
In order to realize the conversion and unification of the data in different datum frames , converting parameters through robust estimation is put forward when the precision index of the two different coordinates cannot be obtained
5.
Transmission error and the return difference are the most important precision index in the precision gearing system and their influence on servo system is also the most important , so their accurate calculation is a necessary work

In this paper , the drive theory of the large ratio friction transmission is studied ; a new type elliptical cam wave generator is designed ; the large ratio friction transmission prototype is designed and manufactured ; based on the ansys finite element method software , structure of the elliptical cam is analyzed ; precision index of the manufactured large ratio friction transmission prototype , such as transmission accuracy , least step , stability of the least step , load capacity is measured by the absolute rotary encoder . by analyzing the measurement data and research content , it is think that the new elliptical cam wave generator could overcome a good many problems brought by processing errors , facilitate size precision adjustments , input moment can be achieved in the form of a pure force couple importing ; through this study , " the large ratio friction transmission prototype " could apply in practical engineering basically

The dimensional globoidal indexing cam mechanism , as a result of the steady movement , accurate , the transmission ceaseless and is suitable for high speed indexing and precise indexing . now it is the most ideal high speed precision indexing mechanism in the world , and it is being widely applied on each kind of automaton and the production line , this mechanisms prospect of application is broad , arouses the people enormous interest . but the examination of the globoidal indexing cam mechanism is a quite weak link , the manufacturers don �� t give the examination because of the difficulty of the geometry shape error examination of the cam contour
