gear reducer的用法和樣例：
例句
- The reducer housing design allows oil from all bearing cavities to be drained through the sump during routine maintenance.
在檢修時，減速箱的設計允許潤滑油從所有軸承空間排出，進入機油箱。 - The gear reducers are sealed units requiring periodic lubricant change.
齒輪減速器是整體密封裝置需要定期更換潤滑劑。 - It has been proved in practice that the method is feasible for the optimal design of gear reducers.
故筆者應用模糊數學中的貼近度概念對二級圓柱齒輪減速器進行多目標尋優。
