Relative movement between machine components and the constraints applied.
Constraint applied to the movement - About a Point
Continuous Movement
The movement will be rotation, and the arrangement can therefore make repeated use of accurate surfaces
Oscillating Movement If only an oscillatory movement is required, some additional arrangements can be used in which the geometric layout prevents continuous rotation.
Constraint applied to the movement - About a line
Continuous Movement
The movement will be rotation, and the arrangement can therefore make repeated use of accurate surfaces
Oscillating Movement If only an oscillatory movement is required, some additional arrangements can be used in which the geometric layout prevents continuous rotation.
Constraint applied to the movement - Along a line
Continuous Movement
The movement will be translation. Therefore one surface must be long and continuous, and to be economically
attractive must be fairly cheap. The shorter, moving component must usually be supported on a fluid film or
rolling contact for an acceptable wear rate.
Oscillating Movement If the transitional movement is a reciprocation, the arrangement can make repeated use of accurate surfaces and more mechanisms become economically attractive.
