The crown height of a flat belt pulley mainly depends on:

Explanation:

Crowning of pulley:

• The rim of the pulley of a flat belt drive is slightly crowned to prevent the slipping off the belt from the pulley.
• The crowning can be in the form of a conical surface or a convex surface.
• Generally, if a pulley is made up of two equal cones or convex surface, the belt will tend to climb on the slope and will run with its center line on the mid-plane of the pulley.
• The amount of crown height is approximately 1% of the face width of the pulley and the crown height of a flat belt pulley mainly depends on the Diameter of the pulley.
