Cam Mechanism Apparatus (SMT-TM-21)
Function of cam mechanisms.
4 different shapes of cam: circular, arc, tangent, hollow or
3 different engaging members: roller, plunger, flat plunger or
Cam and engaging member can be exchanged without tools.
Dial gauge for determining the stroke.
Angular scale for determining the angle of rotation.
Cam mechanisms are non-uniform translatable gears that help convert uniform rotating drive
motions into non-uniform drive motions with or without latching. Generally speaking, cam
mechanism consists of cams, engaging members and the frame. The desired movement path
is defined by the geometry of the cam and produced by pressing a contour or a profile on the
engaging member. The SMT-TM-21 unit is used to clearly demonstrate the function of a cam
mechanism. Cams are available in different shapes. A roller plunger, flat plunger or cam
follower can be used as the engaging member. The stroke is determined by measuring the
travel. An angular scale indicates the corresponding angle of rotation.
