However simple, any machine is a combination of individual components generally referred to as machine elements or parts. Thus, if a machine is completely dismantled, a collection of simple parts remains such as nuts, bolts, springs, gears, cams and shafts—— the building block of all machinery[11. A machine element is, therefore, a single unit designed to perform a specific function and capable of combining with other elements. Sometimes certain elements are associated in pairstel, such as nuts and bolts or keys and shafts. In other instance, a group of elements is combined to form a 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 TM. The rotation of this gear on a hub or shaft drives other gears that may rotate faster or slower, depending upon the number of teeth on the basic wheels.Other fundamental machine elements have evolved from wheel and lever. A wheel must have a shaft on which it may rotate. The wheel is fastened to the shafts with couplings. The shaft must restin bearings, may be turned by a pulley with a belt or a chain connecting it to a pulley on a second shaft. The supporting structure may be assembled with bolts or rivets or by welding Proper application of these machine elements depends upon knowledge of the force on the structure and the strength of the materials employed.The individual reliability of machine elements becomes the basis for estimating the overall life expectancy of a complete machine.Many machine elements are thoroughly standardized. Testing and practical experience have established the most suitable dimensions for common structural and mechanical parts. Through standardization, uniformity of practice and resulting economics are obtained. Not all machine parts in use are standardized, however. In the automotive industry only fasteners, bearings, bushings, chains, and belts are standardized. Crankshafts and connecting rods are not standardized.
