direct-drive gear

基本解释

At the same time William patented a new two-gear direct drive reel.
同时威廉专利两年新齿轮直接驱动辘。
Foot mounting brackets are available also, when the pump must be run slower than direct-drive speeds allow, with belt or gear-reduction assembly.
当泵的运行速度慢于直接驱动速度时，底座安装支架也是可以的，带有传送带或减速齿轮部件。
As the single-screw pump for the low-speed pump, pump-driven approach more, generally have low-speed motor Direct (6, 8 grade), Gear motor drive, variable speed motor drive, etc…
由于单螺杆泵为低速泵，泵的驱动方式较多，一般有低速电机直联（6级、8级）、齿轮减速电机驱动、无级变速电机驱动等方式。
