However simple, any machine is a combination of individual components generally referred toas machine elements or pmts. Thus, if a machine is completely dismantled, a collection of simpleparts remains such as nuts, bolts, springs gears, cams and shafts-the building block of all machinery. A machine element is, therefore, a single unit designed to perform a specific function andcapable of combining with other elements. Sometimes certain elements are associated in pairs,[2]such as nuts and bolts or keys and shafts. In other instance, a group of elements is combined to forma subassembly, such as bearings, couplings, and clutches.
The most common example of a machine element is a gear, which, fundamentally, is a combination of the wheel and the lever to form a toothed wheel. The rotation of this gear on a hub or shaftdrives other gears that may rotate faster or slwer, depending upon the number of teeth on the basicwheels.
Other fundamental machine elements have evolved from wheel and lever. A wheel must have ashaft on which it may rotate. The wheel is fastened to the shafts with couplings. The shaft must restin bearings, may be tumed by a puUey with a belt or a chain connecting it to a pulley on a second shaft. The supprting structure may be assembled with bolts or rivets or by welding. [41 Proper appli-cation of these machine elements depends upon knowledge of the force on the structure and thestrength of the materials employed.
The individual reliability of machine elements becomes the basis for estimating the overall life expectancy of a complete machine.
