A Rapid Measuring Method for Roller Gear Cam Center Distance Error

For the complexity of its space surface,the rapid measuring technology of machining errors for roller gear cam has always been a difficulty.In this paper, the NC machining technology of roller gear cam is introduced first, then a rapid measuring method for roller gear cam center distance error is put forward,and a error analysis model is established, last the machining experiment is done to verify the feasibility of the method.
