Machine elements
A machine is any device that uses energy to perform some activity. In common usage, the meaning is that of a device having parts that perform or assist in performing any type of work. A simple machine is a device that transforms the direction or magnitude of a force without consuming any energy. The word ‘machine’ is derived from the Latin word ‘machine’, which means, expedient, remedy. It may be anything from such an elementary machine as a wedge or a lever to a steam turbine. In practice such simple machines as levers, wedges or pulleys are not spoken of as machines. This name is used for instruments consisting of many elements.
There is, of course, an enormous number of different machines, such as printing machines, machine tools, sewing machines, combustion engines, refrigerators, etc. Although each of this consist of different parts and elements, there are some machine elements that are common to most machines.
Every machine has a frame on which the other parts are mounted and the method of joining these parts to each other is more or less the same in all machines. Two pieces of metal can be joined into one piece by welding them together, which is done by either gas welding or electric welding. A bolted join is achieved by means of nuts and bolts. A bolt consists of the head and the shank with the thread.
Many parts of a machine are mobile. A shaft, for instance, rotates about its axis, and in order to make this motion possible, it is mounted in bearings. Ball bearings and rolled bearings are, of course, preferable, since they reduce friction and require less lubrication. If we want to connect two shafts together, we couple them. Some well known couplings are flange coupling and the sleeve or muff. If the two shaft are not permanently coupled to each other, but can be made to engage and disengage, the coupling is called a clutch. Jaw clutches are widely used, but friction clutches are also used where the shafts require to be connected while running. Wheels are mounted on shafts by means of keys.
