Some terminologies of cam:
|
Cam Profile |
It is the surface area of a cam where the follower touches. |
|
Base Circle |
It is the smallest circle of a cam profile drawn from the center of rotation of the cam. |
|
Trace Point |
By this point, we can trace the cam profile. |
|
Pitch Curve |
This curve is generated if we assume the cam is fixed and the trace-point of the follower moves around the cam. |
|
Pressure Angle |
It is formed between normal to the pitch curve and line of motion of the follower. |
|
Pitch Point |
At this point the pressure angle is maximum. |
|
Pitch Circle |
It is the circle which passes through the pitch point. |
|
Prime Circle |
This is a circle drawn tangentially to the pitch curve and concentric to the base circle. |
