Shredding machine incorporating a torque cushioning assembly

摘要: A shredding machine of the general type employed for comminuting difficult to shred material incorporates a torque cushioning device purpose minimizing breakage teeth or knives apparatus when encounter metal other objects which impose overload on rotating teeth. The drive motor is coupled shafts carrying by means transmission assembly such as speed reducer box. shaft mounted upon input comminuter so that casing can rotate relative fixed frame about axis its supporting shaft. An arm fixedly biased springs frame. Application shafts, engaging hard object, produces reaction tending frame, this rotation being resiliently resisted cushion impact
