Synopsis • Machinery s Handbook Pocket Companion is designed for anyone in the machine trades for whom convenient access to just the most basic data is at a premium. Extremely concise yet authoritative, this invaluable tool draws on the wealth of tables, charts, and text in the Machinery s Handbook, 30th Edition. Much of the subject matter is reorganized, distilled, or simplified to enhance this book s usability and to keep its bulk down.
Both practitioners and students will find the Pocket Companion to be a convenient ready-reference to keep nearby while working on the shop or factory floor or learning the fundamentals in the school lab. While it serves as a complementary text, this book does not replace the Handbook.'
Flat belt drive in the machine shop at the A belt is a loop of flexible material used to link two or more rotating mechanically, most often parallel. Belts may be used as a source of motion, to efficiently or to track relative movement.
Belts are looped over and may have a twist between the pulleys, and the shafts need not be parallel. In a two pulley system, the belt can either drive the pulleys normally in one direction (the same if on parallel shafts), or the belt may be crossed, so that the direction of the driven shaft is reversed (the opposite direction to the driver if on parallel shafts). As a source of motion, a is one application where the belt is adapted to carry a load continuously between two points. A small section of a wide flat belt made of layers of leather with the fastener on one end, shown in an exhibit at the in Flat belts were widely used in the 19th and early 20th centuries in to transmit power in factories.

Flat belts are still used today, although not nearly as much as in the line-shaft era. The flat belt is a simple system of power transmission that was well suited for its day.
It can deliver high power at high speeds (500 hp at 10,000 ft/min, or 373 kW at 51 m/s), in cases of wide belts and large pulleys. But these wide-belt-large-pulley drives are bulky, consuming lots of space while requiring high tension, leading to high loads, and are poorly suited to close-centers applications, so V-belts have mainly replaced flat belts for short-distance power transmission; and longer-distance power transmission is typically no longer done with belts at all. For example, factory machines now tend to have individual electric motors. Because flat belts tend to climb towards the higher side of the pulley, pulleys were made with a slightly convex or 'crowned' surface (rather than flat) to allow the belt to self-center as it runs.
Flat belts also tend to slip on the pulley face when heavy loads are applied, and many proprietary were available that could be applied to the belts to increase friction, and so power transmission. Flat belts were traditionally made of leather or fabric. Today most are made of rubber or synthetic polymers. Grip of leather belts is often better if they are assembled with the hair side (outer side) of the leather against the pulley, although some belts are instead given a half-twist before joining the ends (forming a ), so that wear can be evenly distributed on both sides of the belt. Belts ends are joined by lacing the ends together with leather thonging (the oldest of the methods), steel comb fasteners and/or lacing, or by gluing or welding (in the case of polyurethane or polyester).
Flat belts were traditionally jointed, and still usually are, but they can also be made with endless construction.
