It can be seen from the characteristic coefficient table that the PLG7 coupling Q=5.554 meets the performance requirements. The rotation speed is 1500r/min, the eccentricity S=90mm, s>S, so it meets the requirements.
A2 recommends that the center distance of the two parallel shafts connected by the coupling selected ranges from 0.25S to 0.95S. Additional notes:
