V - BELTS

Belts basic function is power transmission or turnover moment transmission over the pulleys from one shaft (axle) to enother.

Lp, Lw
- belt pitch lenght of tensioned V-belt in netural fibers the V-belt section which keep the same length when being deformed in sectio during the transition of the V-belt from the rectilineal to the circular motion under the constant V-belt tension
La
- outside V-belt length measured on the outer V-belt base in tensioned condition
Li
- inside V-belt length measured on the inner V-belt base in tensioned condition
b
- V-belt width – longer base of trapezoidal V-belt profile
h
- V-belt height – height of the trapezoidal V-belt profile
bw
- pitch V-belt width – the width of a V-belt on the spot of the neutral fibres of the belt
dw
- pitch pulley diameter – diameter of cylindrical surface – the surface staight lines of which are determined by the pitch pulley groove width
