The calculation of belt velocity (peripheral velocity) is not really necessary, as the power rating tables are based on pulley diameter and speed: v = d1nk d2 ng For multiple drives, the number of V-belts required is calculated from z= PcB PN c1c3 (14.46) (14.45)

The arc of contact factor c1, the service factor cB, and the belt length correction factor c3 can be found in the manuals of the manufacturers. The power rating PN of each belt based on the selected pitch diameter dw1 of the smaller pulley, the corresponding speed n1, and the speed ratio can be derived from tables. These tables also contain the nominal values of the service-correction factors to be used. When the guidelines mentioned in the design of a V-belt are observed, the belt life to be expected is 24 000 hours (h) of operation. As for flat belts, the bending frequency is fb = Normal bending frequencies are fb < 30 per second for endless standard V-belts fb < 60 per second for endless narrow-V-belts The belts have to be pretensioned to limit belt slip to 1 percent. Improperly pretensioned belts have a life substantially shorter than the 24 000 h mentioned. The necessary initial tension will lead to equivalent shaft or bearing loads. The approximate equation for the calculation of the required average shaft tension force is Fw aP v 1.5 a 2 (14.48) vz l (14.47)

where P = power to be transmitted and v = belt velocity. More accurate methods may be found in the manufacturers publications containing a description of the correct initial tension adjustment by force and deflection measurements at the center of the belt side. The different belt types are distinguished by section dimensions; the configurations, however, are distinguished by belt construction. Figure 14.20 shows the most widely used V-belt configurations. V-belts consist of the following firmly vulcanized elements: 1. Intermediate ply of high-strength cord (cotton, polyester) for transmission of the rope-pull force 2. Highly elastic belt body (rubber, plastic) for transmission of the peripheral forces between the belt flanks and the cord ply

3. Impregnated wear-resisting fabric coat (textile fibers) for transmission of the friction forces between the belt flanks and the V-belt pulley Because of its higher modulus of elasticity, the cord ply forms both the neutral axis and the pitch diameter dw of the V-belt in the groove, i.e., that diameter which is relevant for the transmission of peripheral velocity. The endless standard V-belts (Fig. 14.20a) in accordance with ISO R606 are supplied in specified lengths and cannot be shortened. Endless narrow-V-belts (Fig. 14.20c) in accordance with ISO R 459 and R 460 are most widely used today. Their power transmission capacity is higher than that of standard V-belts of the same pitch width. FO-type V-belts (Fig. 14.20b), made by the Continental Gummi-Werke AG, are distinguished by their basically different construction. They are a promising new development superior to others for the unusually small change of length their tension members undergo when loaded. Transverse short fibers in the rubber filler lead to high lateral stiffness with high flexibility in the direction of belt travel. By grinding the flanks, the traveling accuracy of the FO-type V-belt can be improved systematically. The Continental belts of this type are manufactured as endless standard V-belts of small section dimensions and as endless narrow-V-belts.
