【摘要】 针对普通外啮合齿轮马达的主要缺点，提出并阐明了一种新型多齿轮复合齿轮马达的工作原理，推导了该种齿轮马达的排量公式、瞬时扭矩公式，并对输出扭矩脉动和该齿轮泵主要元件的径向力做了定性分析，结果表明该种系列的马达性能明显优于其它种类的马达，具有良好的推广前景。更多还原

【Abstract】 A realistic form of a new-typed multi-gear motor is advanced according to themain defects existing in the yeneral-gear motor. The flow charactristic and radial force ofthe motor are analyzed based on the example. The conclusion is obtained that the technicalper formance of this motor wins clearly advantage over other pumps through discussing allkinds of oil motor’s technical performance.更多还原
