GM系列液压马达是本公司结合多年实践经验、在意大利技术基础上进行设计改进的一种新型产品。GM液压马达主要特点如下：

　　1、由于活塞与摆缸不存在侧向力，活塞底部设计成静压平衡，活塞与曲轴之间通过滚动轴承传递扭力，减少了传力过程中的摩擦损失，因而GM系列液压马达具有

　　很高的机械效率，较高的起动扭矩（起动时机械效率0.92以上）的特点。

　　2、平面配流器（专利技术）简单可靠，密封性能好，泄漏很少，活塞与摆缸之间用塑料活塞环密封无泄露，因而具有很高的容积效率（可达0.98）。

　　3、由于结构上减少了磨擦损失，提高了密封性能，因而低速稳定性很好，可以在1r/min工况下平稳运转，调速范围大。

　　4、由于活塞与轴承套通过卡环贴牢不存在间隙，因而该系列液压马达可以作泵工况下运转。

　　5、该系列液压马达压力高，重量轻，体积小，比功率高。

　　6、由于结构简单，设计合理，采用负荷能力大的轴承，因而工作可靠，寿命长，噪音低，传动轴允许承受径向负荷，旋转方向可逆。

　　GMseries hydraulic motor is a new type ofproduct ofour company, which based on years practical experience and designed and improved the original products

　　on the basis ofltalian technologies. GMhydraulic motor mainlyhas the followingcharacteristics:

　　1.As the piston and the tilt cylinder have no side force ,the piston bottom is designed to be static pressure balance. The torsional force is transferringbetween the

　　piston and the crankshaft through rollingbearing,so the friction loss duringthe transferringprocess of force is reduced. Therefore, GMseries hydraulic motor has such

　　features as: veryhigh mechanical efficiencyand comparativelyhigh startup torque(mechanical efficiencyofover 0.92 duringstartup).

　　2.The plane distributor (patented technology)is simple and reliable with perfect seal performance and almost no leakage. The plastic piston ringis used to seal

　　between the piston and the tilt cylinder, so it has veryhigh volumetric efficiency(can be as high as 0.98).

　　3.As the structure ofthis product has reduced friction loss and enhanced the seal performance, the product has perfect stabilityat low speed. It can stablyrun at 1r/

　　min workingcondition and has bigspeed regulation range.

　　4.As the piston is jointed closelywith bearingbushingwithout anyclearance, this series ofhydraulic motor can run at pump workingcondition.

　　5.This series ofhydraulic motor has high pressure, light weight, small bulk and high spesific power.

　　6.As this series hydraulic motor has simple structure, reasonable design and adopts bearingwith bigload ability, it can work reliablyand has longlife and low noise;

　　thetransmission shaft allows endureradial load andtherotational direction isreversible.

　　◆产品适用范围/Applicable range of products:

　　由于GM系列液压马达具有上述一系列特点，因而它的适用范围广，可以在注塑机、轻工机械、工程机械、冶金设备、石油、煤矿、地质勘探、铁路、船舶、环保、

　　机床、农机等各种机械的液压传动系统中应用。

　　As GMseries hydraulic motor has the above characteristics, it has wide application range. it can be applied in the hydraulic transmission systems ofvarious types

　　ofmachineryin plastic injection machine, light industrymachine, engineeringmachine, m e t allurgical equipment, petroleum, coal mine, geological prospecting, railway,

　　ship, environment protection, machine tool and agricultural machine industries.
