SECTION 3 COMPARISON GRAPHS In order to provide comparison of performances of different pitch drives, several graphs have been developed. Figure 4 shows numerical values, plotted in logarithmic scale, of Rated Horsepower vs. Speed (rpm) of faster shaft. MXL = .080" pitch XL = .200" pitch L = .375" pitch H = .500" pitch XH = .875" pitch XXH = 1.250" pitch 20,000 10,000 2 mm GT MXL 3 mm GT XL 5,000 4,000 3,450 2,500 1,750 5 mm GT H L 1,160 870 690 575 400 300 Speed (rpm) of Faster Shaft XH XXH 200 150 100 .01 .015 .02 .03 .04 .05 .07 .1 .15 .2 .3 .5 .7 1 1.5 2 3 4 5 7 10 15 20 30 40 50 70 100 150 200 300 400 500 Rated Horsepower Fig. 4 Comparative Belt Pitch Selection Guide T-6
Figure 5 shows an illustrative graph representation of horsepower ratings over a wide speed range of the belt types commonly used. The graph assumes that belt widths and pulley diameters have been chosen such that they provide realistic comparison of product capability. Rated Horsepower 6 5 4 3 2 1 0 Fig. 5 Horsepower Ratings at High Speed Figure 6 provides a comparison of the rated torque carrying capabilities of synchronous belts, on small diameter pulleys at low speeds. The pulley diameters and belt widths represent a realistic comparison.
