load torque formula for drag chain conveyor

What is Catenary Sag?

Remove chain lengths as required to maintain proper chain sag. If the sag is too long, shut off your conveyor, and follow Lockout-Tagout (LOTO) procedures. Remove the pin from one chain link near the drive sprocket so the chain can be supported. Pull the overlapping ends of the chain hand-tight to determine how many lengths can be removed. Get price

How to Select and Size Gearmotors for Conveyor

Aug 08, 2019Gravity torque only needs to be considered when the belt is not mounted horizontally. It is a positive number when the load is moved upward, and a negative number when the load is moved downward. Equation 3: T GRAVITY (oz-in.) = r WLOAD sin φ. In our example, the conveyor is not inclined, therefore φ= 0, which means that T GRAVITY = 0. Get price
