Torsionally Elastic Agricultural PTO Drivelines and Their Application

Farm implement sizes are increasing rapidly. The increases in rotating mass, the uneven load cycles, and the high probability of impact loads inherent in farm applications result in peak drive train torque loads which are very high compared to the average torque required.

This paper discusses the conditions under which these peak torques arise, and the effects of torsional elasticity in reducing these peak torques, thus reducing stresses on all drive train components such as universal joints, gears, shafts, and so forth.
