Abstract

The invention discloses an apparatus for measuring the pressure angle of a cam by using double rollers to automatically searching for a normal line. The apparatus comprises a frame, a follower mechanism, the cam and a pressure angle measuring mechanism. According to the invention, the pressure angles of disc-form cams with any contours can be rapidly and accurately measured, the size of the pressure angels of the contours of the cams can be displayed in real time, the size and the position of the maximum pressure angle can be accurately found, and by using the apparatus, students can parse the pressure angles and can also have a better understanding of the concept of the pressure angles.
