3.1.1 Determining Design Power P d The optimal belt drive tension is dependent on many factors. The goal is to tension the belts just enough to prevent them from slipping, however it is rare that all of the information necessary to do this is known. The formula for Design Power below covers the vast majority of belt drives.
mechanics machines. Two Pulley Connecting Belt Design and Calculations . Mechanics and Machine Calculations. The following equations will determine: Speed Ration, Arc of contact, Tension ration for belt about to slip, Power Capacity, Pulley Torque, Initial Tension
Common Calculations for Proper Design Belt Length . When the head and tail pulley are the same size: L= D d /2 x 3.1416 2C When one pulley is larger than the other pulley: L= D d /2 x 3.1416 2C D-d 2 /4c. Belt Speed. Expressed in feet per minute FPM S=D x RPM x .2618 x 1.021. Belt Load

The calculation methods of Viet Phat Conveyor Belt specifi ions shared below can similarly apply or interpolate the corresponding specifi ions between different conveyor lines. Viet Phat Conveyor Belt shares with you the following article on conveyor belt design calculation instructions with quite a wide content coverage, so the post is long.
The CEMA Conveyor Design Manual provides this equation to calculate effective belt tension. Te = LKt Kx KyWb 0.015Wb Wm LKy H Tp Tam Tac These parameters enable the designer to calculate belt tension required to overcome:
