XHBD4

Product Overview:

The XHBD five-cylinder radial piston hydraulic motor range incorporates most of the components from the XHS series, which has been widely acclaimed for its high performance and reliability. An innovative intermediate plain bearing design, manufactured using the latest materials and machining processes, has further expanded the XHS hydraulic motor range. The XHBD motors can now be supplied with variable displacement, tapered roller bearings for axial forces, a hollow output shaft and a counterbalance block to reduce vibration at high speeds. The use of tapered roller bearings allows the new motor to carry a portion of the axial load, and the radial load carrying capacity has also been significantly increased.

The XHBD two-speed motor is the first to be produced in China and has been successfully declared a national invention patent. The main parts are manufactured by an imported five-axis machine and machined in a single operation.

Displacement change: The change of displacement of the XHBD series motor is achieved by changing the eccentric distance of the motor crankshaft. It can be adjusted smoothly from high to low displacement and vice versa, either dynamically or statically, by means of an external low pressure control signal.

Free wheel: the BD series motors do not allow cavities.

Application and operation: the sliding bearings on the shaft have a very low coefficient of friction and the motor can be started with a high torque and at the same time has a high mechanical efficiency at both high and low displacements. The maximum speed of the motor so far depends on the flow rate of the oil distributor mounted on the motor.

Starting and low speed torque: BD motors are able to maintain a good speed stability at low speeds. The minimum stabilisation speed depends on the displacement of the motor. The motor is able to maintain a constant torque output at low speeds as well, without excessive fluctuations due to low speeds, crawling or just starting up.

Product range of application.

As the XHBD series hydraulic motor has a series of characteristics mentioned above, it has a wide range of application and can be used in the hydraulic transmission systems of various machines such as injection moulding machines, light industry machinery, engineering machinery, metallurgical equipment, petroleum, coal mines, geological exploration, railways, ships, environmental protection, machine tools, agricultural machinery, etc.

Product Model Description.

制动系统液压马达是一种负荷能力更高轴配流液压马达，能适用高压力中的长期性运行。液压马达生产厂商选用输出轴和配流组织的整体设计、镶嵌齿固定转子、两侧滚柱轴承支撑点和专用进口旋转密封使电机在相对较高的背压下工作。

液压系统的功效为根据更改压强增大相互作用力。一个完整的液压系统由驱动部件、执行部件、控制部件、辅助部件(附件)和齿轮油五部分组成。液压系统可分为液压传动系统和液压传动系统两大类。液压传动系统以传送动力和健身运动为基本功能。液压传动系统使液压系统导出达到特定的性能规定(特别是动态性能)，一般说液压系统主要是指液压传动系统。

一般而言，在相同输出功率下，一台性能良好的高速液压行走马达，应具备：输出功率质量比大，额定压力和转速高，较低平稳转速比低，容积效率和总高效率，运行机械能高，移动转速比小，承担冲击载荷能力强，噪音低，动态特性好，使用寿命长等优点。
