  • W.M. Berg manufactures several styles of gears. Each gear has and serves its own particular application. Listed below are brief descriptions and application notes for the variety of available styles. Further information can be obtained from numerous gear and mechanical design handbooks, or by contacting our engineering department Gear Types Spur Gears are the most recognized style of gear. Spur Gears are used exclusively to transmit rotary motion between parallel shafts, while maintaining uniform speed and torque.

  • Series.—Some hand calculations, as well as computer programs of certain types of mathematical problems, may be facilitated by the use of an appropriate series. For example, in some gear problems, the angle corresponding to a given or calculated involute function is found by using a series together with an iterative procedure such as the Newton-Raphson method described on page 33.

  • There are many different types of organisation, none of them necessarily the best or the worst but all geared towards enabling an organisation to achieve its objectives as quickly, easily and inexpensively as possible. Most management writers have offered differing views on which types of organisation can work best in which contexts. All these views are valid but some may not be as appropriate to certain kinds of organisation as others.
