Description: Entanglements around rotating. power take-off shafts continue to cause farm injuries. Research is. necessary to understand the factors that contribute to entanglements. so that, if possible, design modifications can be made to. reduce their probability. In this study, five parameters (material. moisture content, joint angle, approach direction, approach. velocity, and material length) were investigated using a Cardan. joint rotating at 1140 rpm. A total of 258 entanglements occurred. out of 720 trials all entanglements occurred at the jaws of the. Cardan joints. Of the two approach directions tested, entanglements. were more likely to occur when the periphery of the. rotating joint moved toward the free end of the hanging yarn.. The moisture content of the yarn does not seem to contribute. to the probability of entanglement for single strands of yarn.. Long strands of yarn tended to be entangled more readily than. short strands of yarn. More entanglements occurred with an. approach speed of 10 cm/min than with an approach speed of 50. cm/min. Joint angle plays an important role in determining the. probability of entanglement for a single strand of yarn. Positive. joint angles cause fewer entanglements than negative joint. angles. Further investigation is needed to explain this observation.
Keywords: power take-off, entangle, joint angle.
