CAM MECHANISMS 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） Cam makes a higher kinematic pair with follower. Cam mechanisms are widely used because with them, different types of motion can be possible. Cams can provide unusual and irregular motions that may be impossible with the other types of mechanisms. However, the manufacturing of cams is expensive and the wear effect due to the contact stresses is a disadvantage. On the other hand, cams are not proper for the systems with high speeds and heavy loads. 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） Classification of Cams According to kinematic structure: 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） According to shape of the cam: Spherical, Helical, Conical, 3 dimensional 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） According to the type of contact: Force closed Form closed 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） Classification of Followers • According to the construction of the surface in contact(roller, flat faced, cylindrical, spherical) • According to the type of movement (translating or oscillating) • The translating follower is also classified as radial or off-set according to the location of movement with respect to the cam rotation axis. ：奉献教育（店铺） 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） 有缘学习更多+谓ygd3076考证资料或关注桃报：奉献教育（店铺） BASIC CAM MOTION CURVES • In this section some well known motion curves will be explained for the rise portion of the motion curve only. • 1.
