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:
This standard was proposed and incorporated by the Xi'an Heavy Machinery Research Institute of the Ministry of Machinery Industry. This standard is drafted by Xi'an Heavy Machinery Research Institute. The main drafter of this standard is Wu Shiqin.
