One way to convert rotational motion into linear motion and viceversa is via the use of a mechanism called the scotch yoke, whichconsists of a crank C that is connected to a slider B via pinA. The pin rotates with the crank while sliding within theyoke, which, in turn, rigidly translates with the slider.

CNC Linear Motion Systems. The linear motion system plays a vital role in any linear CNC machine, and CNC routers are no exception. Without these systems coupled with a drive system, a CNC router would be of little use. The LM system is responsible for three primary tasks.

A lever is a rigid bar that moves on a fixed point called the fulcrum when a force is applied to it. Movement is made possible in the human body by lever systems which are formed by our muscles and joints working together. An understanding of the lever systems in the body helps us to understand how movement is possible. Details

•1. Linear Motion : Let H= Total follower rise (Stroke) = angular rotation of the cam corresponding to the total rise of the follower. a=0 • The motion curve and velocity and acceleration curves are as shown. Note that the acceleration is zero for the entire motion (a=0) but is infinite at the ends.

Oct 30, 2015· Benefits of air bearings over mechanical bearings. Air bearings are linear (or rotary) guides, and as such, are simply one part of a complete motion system. For a drive mechanism, the most common technology used in conjunction with air bearings is the ironless linear motor, due to its high precision and stiffness.

In order to generate linear motion, in mechanics and robotics, affordable and simple to operate devices called linear actuators are most commonly used. Their moving capabilities can depend on different mechanical/electro principles: pneumatics, hydraulics, and voltage. The latter type of actuators is the most compact and accessible.
