rexroth齿轮泵的工作原理
rexroth齿轮泵优点：结构简单紧凑、体积小、轻、工艺性好、价格便宜、自吸力强、对油液污染不敏感、转速范围大、-冲击性负载，维护方便、工作-。
缺点：径向力不平衡、流动脉动大、噪声大、效率低，零件的互换性差，磨损后不易修复，不能做变量泵用。
困油现象
原因：液压油在渐开线齿轮泵运转过程中，因齿轮相交处的封闭体积随时间改变，常有一部分的液压油被密封在齿间，如图所示，称为困油现象，因液压rexroth齿轮泵油不可压缩将使外接齿轮产生-的振动和噪声，影响系统正常工作。
困油现象
措施：在前后盖板或浮动轴套上开卸荷槽，开设卸荷槽的原则：两槽间距为小闭死容积，而使闭死容积由大变小时与压油腔相通，闭死容积由小变大时与吸油腔相通。

azmn-22-020ucb20px、pgh4-2x/040lr18vu2使用方法：
齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力完全取决于泵出处阻力的大小。
