The belt is non-slip engagement with constant angular velocity, relatively maintenance-free, and economical. Timing Belt Failure Analysis Shock Load Appearance: Snapped Cause 鈼?Shock loading in belt drives occurs when higher than normal intermittent or cyclic torque loads are generated by the driven equipment. These shock loads result in higher than normal belt stresses and can act as a catalyst for belt failure. 鈼?Severe shock loads can result in belt tensile breaks with a ragged and uneven appearance as illustrated in Figure 4. The particular belt teeth engaged in the sprocket at the instant of the shock load may also develop root cracks and/or exhibit tooth shear. 鈼?Figure 5 illustrates how root cracks caused by shock loading can propagate through the teeth. Cracks forming at the tooth roots sometimes move towards the tooth tips. Teeth containing multiple cracks may then shear, leaving only a portion of the tooth behind. Solutions If the drive shock loads cannot be eliminated, the belt tensile strength may need to be increased or the synchronous belt drive replaced with a more forgiving V-belt drive system capable of intermittent slip.Timing Belts factory website:http://www.pioneerdrivebelt.com/timing-belts/
