A_4V系列通轴泵是一种新型的通轴斜盘式轴向柱塞泵,几乎集典型闭式系统中除马达式缸以外的所有液压件为一体,其柱塞锥面分布结构,不带保持架的长圆柱滚子轴承,以及其有多种控制方式,保证了产品的高压高速性能,满足了现代主机全液压传动,高功率重量比和操作舒适性的要求,可广泛地用于新一代的建筑工程机械、矿山机械、冶金、港口设备以及地面军事设备上。本刊将这种泵的结构,理论分析及关键制造工艺等内容以专栏形式分两期刊出,以飨读者。
A_4V series through-shaft pump is a new type of through-shaft swash plate type axial piston pump. It integrates nearly all hydraulic components except the motor-type cylinder in a typical closed system. Its plunger-cone distribution structure does not The cage’s long cylindrical roller bearing and its various control methods ensure the high-pressure and high-speed performance of the product. It meets the requirements of modern host hydraulic drive, high power-weight ratio and operating comfort, and can be widely used in new applications. A generation of construction machinery, mining machinery, metallurgy, port equipment, and ground military equipment. The journal will present the structure, theoretical analysis and key manufacturing processes of this pump in two columns in a column format for readers.
