Outside length in mm: 1905 = effective outside length La = 750 · 25.4 10 La = 1905 mm application examples The use of optibelt SK wedge belt drives in profiles 3V/9n and 5V/15n is recommended for machines exported to countries such as the uSA and Canada where these belt profiles are standardised and predominantly used. Profile 8V/25n is primarily employed in very heavy duty drives such as mills or stone crushers. As these wedge belts transmit very high levels of power, they can sometimes form a more compact drive than the SPC profile. For this reason, the 8V/25n profile has continued to be used in Europe for such applications. A further advantage is the fact that single wedge belts can be replaced by kraft- bands, without changing the pulley geometry, in case unexpected belt vibration problems develop. Drive calculation Drive calculations follow the procedures described in this manual. The power value of the SPz applies for drives with the 3V/9n profile. The value of the SPB profile applies for 5V/15n. The datum diameters of the SPz and SPB wedge belts have to be the same as the external diameters of the 3V/9n and 5V/15n. Slight mathematical differences in the rotational frequency and transmission have no practical influence. Slight differences in the theoretical drive speed and the speed ratio are not significant in practice. © ArnTz OPTIBELT GrOuP, GErmAny 9
