Title
(EN) Low-speed large-torque valve flow assignment inner curve radial plunger type high-water-based hydraulic motor
(ZH) 一种低速大扭矩阀配流内曲线径向柱塞式高水基液压马达
Abstract
(EN) The invention discloses a low-speed large-torque valve flow assignment inner curve radial plunger type high-water-based hydraulic motor which is suitable for industrial and mining enterprises. A railis arranged on the outer side of a rotor of the motor, a liquid return shell is connected to the left side of the rail through a bolt, a liquid feeding shell is connected to the right side of the railthrough a bolt, a bearing is arranged on the left side of the liquid return shell, a main shaft is arranged in the bearing, the main shaft is connected with the rotor, a liquid return flow assignmentcam is arranged on the main shaft, a liquid return flow assignment body a is arranged on the liquid return flow assignment cam, and a liquid feeding flow assignment cam is arranged in the liquid feeding shell and provided with a liquid feeding flow assignment body a; plungers are installed in plunger holes in the rotor, and arc bulges are arranged in the liquid feeding flow assignment cam and theliquid return flow assignment cam at intervals; and the plunger hole corresponding to each plunger is respectively connected with flow passages of the liquid feeding flow assignment valve and the liquid return flow assignment valve, the liquid feeding flow assignment valve is connected with a liquid return flow assignment body b, and the liquid return flow assignment valve is connected with a liquid feeding flow assignment body b. The low-speed large-torque valve flow assignment inner curve radial plunger type high-water-based hydraulic motor is good in sealing performance, compact in structure, high in work pressure, high in reliability and long in service life.
(ZH) 本发明公开一种低速大扭矩阀配流内曲线径向柱塞式高水基液压马达,适用于工矿企业。马达转子外侧设有轨道,轨道左侧螺栓连接有回液壳体、右侧螺栓连接有进液壳体,回液壳体左侧设有轴承,主轴设置在轴承内,主轴与转子连接,主轴上设有回液配流凸轮,回液配流凸轮设有回液配流体a,进液壳体内设有进液配流凸轮,进液配流凸轮上设有进液配流体a;转子上的柱塞孔内均安装有柱塞,进液配流凸轮和回液配流凸轮间隔设有圆弧凸起;每个柱塞对应的柱塞孔分别与进液配流阀和回液配流阀的流道连接,进液配流阀连有回液配流体b,回液配流阀连有进液配流体b。其密封性好、结构紧凑、工作压力高、可靠性高使用寿命长。
