MACHINE MOTION

Welcome to class!

In today’s class, we will be talking about machine motion. Enjoy the class!

Transmission of linear motion

(i) Slots:

A slot is a whole with different shapes such as triangular, circular, rectangular or square. A slot usually has a corresponding shaped object that can be moved in and out of the slot.

For example, a rod can be moved in and out of a cylindrical pipe. Again, a drawer in a cabinet follows a straight line path because it is guided by the cabinet slot.

(ii) Slides:

A slide is a rigidly supported object over which another can move. Arrangement of mechanisms that operate as slides include sliding doors, gates and bolt lockers.

(iii) Levers and Linkages:

This is an arrangement of a pivoted rigid bar used to transmit linear motion. When more than two levers are combined, one of the arrangement becomes the linkage between the driver arm lever and the driven arm lever.

In the arrangement above, linear motion can be transmitted over a long distance. In both instances, motion can be transmitted from the driver’s arm to the driven arm without changing the direction.

The application of levers and linkages can be seen in many machines such as the automobile bonnet lever mechanism, bicycle arm brake lever and the gas pedal throttle lever arrangement.
