It doesn't look >180 degrees to me.sam0916 said:
The angle of wrap is the angle formed by a belt or rope as it wraps around a pulley or other rotating object.
The angle of wrap affects the amount of friction between the belt and the pulley. A larger angle of wrap results in more surface area contact between the belt and pulley, increasing the friction and therefore the power transmission.
The angle of wrap can be calculated by dividing the arc length of the belt on the pulley by the diameter of the pulley. This value is then converted to degrees.
The ideal angle of wrap for maximum power transmission is typically between 120 and 180 degrees. This provides a good balance between friction and belt tension.
A larger angle of wrap can increase the life of a belt by reducing the stress and wear on the belt. However, if the angle of wrap is too large, it can cause excessive bending and stretching of the belt, leading to premature failure.
