POWER TRANSMISSION
CALCULATION OF BELT SPEED
Belt speed (m/s) = Π x (small pulley diameter mm) x (small pulley rpm)
Ideally, V-belt speed should be approximately 15 m/s to 20 m/s.
Power transmission efficiency drops when V-belt speed is over 22 m/s.
V-belt speed should not exceed 30 m/s.
BELT TENSION SETTING
Damage may occur to the belt due to operation with excessive tension; where under insufficient tension it may slip
and cause a decrease of the transmission efficiency and durability.
Apply a force (see table below) perpendicular to the belt on the center point of the span (L) .
Adjust the deflection (d) so that:
d = 0.016 x L
