direct-drive gear

基本解釋

At the same time William patented a new two-gear direct drive reel.
同時威廉專利兩年新齒輪直接驅動轆。
Foot mounting brackets are available also, when the pump must be run slower than direct-drive speeds allow, with belt or gear-reduction assembly.
當泵的運行速度慢于直接驅動速度時，底座安裝支架也是可以的，帶有傳送帶或減速齒輪部件。
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…
由于單螺桿泵為低速泵，泵的驅動方式較多，一般有低速電機直聯(lián)（6級、8級）、齒輪減速電機驅動、無級變速電機驅動等方式。
