PIX 9.5x1913 La XPZ V-ring

NARROW, CUT AND GROUND V-BELTS XPZ/9.5 (9.7)
V-belts are the most commonly used component in mechanical transmission systems for transferring rotary motion, and thus mechanical energy, from one shaft to another. Their applications range from small domestic appliances, through compressors, blowers and production lines, to the drives of units in motor vehicles, machinery, agriculture, etc.
The basic range of narrow, cut and ground coated V-belts is supplied in XPZ, XPA, XPB and XPC cross-sections. The cut profile represents the highest-performance type of V-belt currently manufactured and supplied. Narrow cut V-belts are used in new drive systems or as a replacement for less powerful belts where there is a need to increase the power transmitted or to extend the service interval for V-belt replacement.

Parameters for identifying the belt’s dimensions and type.
La Outer length (circumference).
Li Inner length (circumference).
Lw=Lp=Ld Calculated length. Measured around the circumference of the neutral fibres, which retain the same length when the belt is bent (approximately at 2/3 of the belt’s height).
b = 9.7 mm Width of the outer base of the belt.
h = 8 mm Belt height.
bw = 8.5 mm Calculated width. The width of the belt at the neutral fibres.
α = 36° Angle formed by the sides of the belt, measured on a straight section whilst the belt is under tension.
