    • The gear pump or motor includes seal plates (30) having a lubrication channel (48, 50) communicating between the shaft bearings and the low pressure side of zone where the gear teeth intermesh. Lubricant flow is directed first through one bearing on one side of the pump and then back through a separate channel to the other bearings on the same side of the pump. Placement of the lubrication channels on the low pressure side of the pump where the volume between intermeshing teeth is increasing and the pressure between the teeth is below inlet pressure ensures that flow reversals in the bearings and lubricant aeration are avoided; and renders bearing flow rate less sensitive to pressure.
    • 齿轮泵或马达包括密封板(30),其具有在轴轴承与齿轮啮合的区域的低压侧之间连通的润滑通道(48,50)。 润滑剂流首先通过泵的一侧上的一个轴承,然后通过单独的通道返回到泵的同一侧上的其它轴承。 润滑通道在泵的低压侧放置,其中相互啮合的齿之间的体积增加并且齿之间的压力低于入口压力确保了轴承和润滑剂曝气中的流动反转被避免; 并使轴承流量对压力不敏感。

    • PURPOSE: A hydraulic pump is provided to reduce vibration and noise and to facilitate manufacture of the hydraulic pump. CONSTITUTION: A hydraulic pump(10) includes a housing(20), two shafts(40,41), and pairs of rotors(5-1,5-2,5-3,5-4,5-5,5-6). A suction pipe for the inflow of a fluid and a discharge pipe for the outflow of the fluid are installed in the housing. The shafts extend from the inside of the housing and rotate in the opposite directions. The rotors are each joined to the shafts and the rotors are rotated through engagement. One of the rotors has at least two protrusions protruded in the radial direction and the other one has receiving grooves for receiving the protrusions. The rotors on a coaxial line are joined to the rotating shafts, with each different phase to engage at each different time.
    • 目的:提供液压泵,以减少振动和噪音,并方便制造液压泵。 构成:液压泵(10)包括壳体(20),两个轴(40,41)和一对转子(5-1,5-2,5-3,5-4,5-5,5- 6)。 用于流体流入的吸入管和流体流出的排出管安装在壳体中。 轴从壳体的内部延伸并沿相反的方向旋转。 转子各自连接到轴上,并且转子通过接合旋转。 一个转子具有沿径向突出的至少两个突起,另一个具有用于接收突起的接收槽。 同轴线上的转子连接到旋转轴,每个不同的阶段在每个不同的时间进行啮合。
