ChipBLASTER, Inc. 62 18.0. BELT INSTALLATION (Cont.): 18.3.1.2. Increase the belt tension until the belt feels snug or taut. Avoid over tensing the belt. 18.3.1.3. Start the drive and apply the most severe load condition. This may be either the motor starting torque or during the work cycle. A belt that is too loose will “jump teeth" under the most severe load condition. When this occurs. gradually increase the belt tension until satisfactory operation is achieved. 18.4. BELT TENSIONING - FORCE DEFLECTION METHOD: 18.4.1. An alternate numerical method can also be used to properly tension the belt on a Synchronous drive. This procedure, commonly referred to as the Force Deflection Method, consists of measuring the pounds of force required to deflect the belt a given amount. 18.4.1.1. Install the belt as per Steps 1 and 2 of the General Method. Measure the span length (in inches) as illustrated in Figure 11. 18.4.1.2. From Figure 11 determine the deflection height required for the drive. The deflection height is always 1/64" per inch of span length. For example. a 32" span length requires a deflection of 32/64" or 1/2". To measure the deflection height place a straightedge from sprocket to sprocket on top of the belt or wrap a string or steel tape around the sprockets on top of the belt. This will serve as a reference line to measure deflection inches. 18.4.1.3. Using the formula at below, calculate the minimum and maximum force values (lbs.). 18.4.1.4. Using a spring scale, apply a perpendicular force to the belt at the midpoint of the span as illustrated in Figure 1. NOTE: For belts wider than 2 inches, it is suggested that a rigid piece of key stock or something similar be placed across the belt between the point of force and the belt to prevent belt distortion. Compare this defection force value to that found in 18.4.1.4. Adjust belt tension accordingly. Actual belt installation tension required depends on peak loads, system rigidity, teeth in mesh. etc. In some instances it may be necessary to gradually increase the belt tension to achieve proper operation of the drive. 18.4
