Equations for Horsepower Ratings

Extensive researeh by ACA members has produeed reliable power ratings for ANS roller ehain drives conforming to the ASME B29.1 standard. The power eapaeity of roller ehain drives operating [Pg.168]

FIGURE 5-16 Sample roller chain power rating chart. [Pg.169]

A well-aligned two-sprocket drive on parallel horizontal shafts. [Pg.169]

Equation 5.5 defines the power rating of ANS roller chains, limited by link plate fatigue strength [Pg.169]

HPi is the horsepower rating limited by link plate fatigue strength is 0.0044 for all standard series chains except no. 41, 0.0044(Z yr5)° for heavy series chains, and 0.00242 for no. 41 chain n is the number of teeth on the small sprocket p is the chain pitch (in inches), R is the speed of the small sprocket (in rpm) [Pg.169]
