direct-drive gear

基本解释

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敺動轆。
Foot mounting brackets are available also, when the pump must be run slower than direct-drive speeds allow, with belt or gear-reduction assembly.
儅泵的運行速度慢於直接敺動速度時，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…
由於單螺杆泵爲低速泵，泵的敺動方式較多，一般有低速電機直聯（6級、8級）、齒輪減速電機敺動、無級變速電機敺動等方式。
