  • Driving mechanism for driving a gear pump for forcing a highly viscous resin
    Patent number: 5522714
    Abstract: A driving mechanism for driving a gear pump of a dual drive type having two shafts comprises a reversing gear having a pair of output shafts which rotate respectively in opposite directions at the same rotating speed, and a pair of gear couplings connecting the gear pump to the reversing gear. One of the pair of gear couplings comprises: a shaft, a first coupling head disposed on one end of the shaft, and a second coupling head disposed on the other end of the shaft. The number z.sub.1 of teeth of the component external spur gears and internal spur gears of the first coupling head is not equal to the number z.sub.2 of teeth of the component external spur gears and internal spur gears of the second coupling head.
