齒輪泵是液壓傳動系統中常用的液壓元件, 在結構上可分為外嚙合齒輪泵和內嚙合齒輪泵大類。外嚙合齒輪泵的優點是結構簡單、尺寸小、重量輕、制造維護方便、價格低廉、工作可靠、自吸能力強、對油液污染不***等。缺點是齒輪承受不平衡的徑向液壓力, 軸承磨損嚴重, 工作壓力的提高受到限制; 流量脈動大, 導致系統壓力脈動大,噪聲高。內嚙合齒輪泵結構緊湊、尺寸小、重量輕, 并且由于齒輪同向旋轉, 相對滑動速度小、磨損輕微、使用壽命長、流量脈動遠比外嚙合齒輪泵小, 因而壓力脈動和噪聲都比較小。內嚙合齒輪泵允許使用較高的轉速, 可獲得較高的容積效率。
2．馬達工況：馬達的作用是將液壓能轉變為機械能.當高壓油從馬達的進油口通過配流盤高壓窗口進入缸體柱塞孔內, 推動柱塞運動, 由于缸體軸線與主軸軸線成一夾角,液壓力通過連桿作用于主軸上, 產生一個切向力, 推動主軸旋轉, 輸出扭矩。同時工作過的油液借助于缸體的慣性旋轉，被擠出柱塞孔，通過配油盤的低壓窗口，從馬達排油口排出。

另外還存在材料金相組織穩定的問題，眾所周知，鋼在淬火后總是會有殘余的奧氏體，該體長時間會轉變成密度小的馬氏體。這樣一來，會使零件尺寸變形，減少間隙。這個因素基本是估計不到的。所以，從這個觀點來看，柱塞采用刃量具鋼為好，或者說采用時效或者冷處理，來穩定金相組織。這個問題在間隙小時就顯得尤為重要了。
