Engineering Tribology, Third Edition

As with the former variation, the 3rd variation of Engineering Tribology presents a radical knowing of friction and put on utilizing applied sciences resembling lubrication and distinctive fabrics. Tribology is a fancy subject with its personal terminology and really expert options, but is very important all through all engineering disciplines, together with mechanical layout, aerodynamics, fluid dynamics and biomedical engineering.

These friction materials may operate either dry or wet (oil) and find applications from tension control in manufacturing processes through overhead cranes, hoists, and industrial brakes and clutches and in farm and garden tractors. Some or all of the following materials, and others, that are now necessary to produce a lining having a high friction coefficient may be embedded in the resin binders used [9].

Friction Materials Cyanamid Mica Glass fibers Vermiculite Graphite 11 Barite Rubber dust Cellulose Petroleum coke Wollastonite Collan Alumina Acrylic fibers Because some of these materials have been classified as hazardous by one or both of the Occupational Safety and Health Administration (OSHA) or the American Conference of Governmental Industrial Hygienists (ACGIH) organizations, dust in the vicinity of their use and storage must be removed by vacuuming or by a dust suppressant according to the time schedules of one or both of OSHA and ACGIH.

Drum brake efficiency may be measured in terms of the ratio of the torque produced by the brake itself to the torque required to activate the brake, also known as the shoe factor; namely, T T ¼ M a Mp F Mf ð2-2Þ Brake efficiency is generally not a design factor in the analysis of drum brakes because it is dependent on too many factors [f1, f2, r/R, A, w, and (sin f)max] Copyright © 2004 Marcel Dekker, Inc. 40 Chapter 3 FIGURE 6 Geometry for calculating the moment due to pressure about point A for an internal shoe brake.

Band brakes are used in many applications such as in automatic transmissions (Figure 1) and as backstops (Figure 5—devices designed to prevent reversal of rotation), for bucket conveyors, hoists, and similar equipment. They are especially desirable in the last-mentioned application because their action can be made automatic without additional controls. I. DERIVATION OF EQUATIONS Figure 2 shows the quantities involved in the derivation of the force relations used in the design of a band brake. Consistent with the direction of rotation of the drum, indicated by N, the forces acting on an element of the band are as illustrated in the lower right section of Figure 2.
