低价供应意大利CALZONI马达、CALZONI电机、 CALZONI液压马达、CALZONI径向柱塞液压马达。意大利Calzoni马达的杰出性能归功于其特、具有专利技术的设计。其原理是通过具有一定压力的容腔液压油（A）将力从柱塞传递到旋转轴 (2)上，而不是向传统马达那样通过杆、活塞、垫片及顶针连接的。压力油是在伸缩油缸(1)中，通过活塞与缸盖间的球面副、缸盖（4）与旋转轴之间的球面副（3）进行密封。通过选用材料与优化设计减少摩擦及泄漏。设计的另一个优点是取消了连接的部件，油缸仅能线性伸缩，因此作用力没有横向分量。这意味着运动部件没有椭圆磨损，油缸的连接处也没有侧向力。
齿轮马达
齿轮马达在结构上为了适应正反转要求，进出油口相等、具有对称性、有单外泄油口，将轴承部分的泄漏油引出壳体外;为了减少启动摩擦力矩，采用滚动轴承;为了减少转矩脉动，齿轮液压马达的齿数比泵的齿数要多。
齿轮液压马达由干密封性差、容积效率较低、输入油压力不能过高、不能产生较大转矩。并且瞬间转速和转矩随着啮合点的位置变化而变化，因此齿轮液压马达仅适合于高速小转矩的场合。一般用于工程机械、农业机械以及对转矩均匀性要求不高的机械设备上。

工作原理，当压力油经固定的配油轴4的窗口进入缸体内柱塞的底部时，柱塞向外伸出，紧紧顶住定子的内壁，由于定子与缸体存在一偏心距。在柱塞与定子接触处，定子对柱塞的反作用力为 。力可分解为和 两个分力。当作用在柱塞底部的油液压力为p，柱塞直径为d，力和之间的夹角为X时，力对缸体产生一转矩，使缸体旋转。缸体再通过端面连接的传动轴向外输出转矩和转速。以析的一个柱塞产生转矩的情况，由于在压油区作用有好几个柱塞，在这些柱塞上所产生的转矩都使缸体旋转，并输出转矩。径向柱塞液压马达多用于低速大转矩的情况下。E-A4VS0180DR/30R-PPB13N00

液压马达按其结构类型来分,可以分为齿轮式、叶片式、柱塞式和其它型式。按液压马达的额定转速分为高速和低速两大类。额定转速高于500r/min的属于高速液压马达，额定转速低于500r/min的属于低速液压马达。高速液压马达的基本型式有齿轮式、螺杆式、叶片式和轴向柱塞式等。它们的主要特点是转速较高、转动惯量小、便于启动和制动、调节(调速及换向)灵敏度高。通常高速液压马达输出转矩不大所以又称为高速小转矩液压马达。低速液压马达的基本型式是径向柱塞式，此外在轴向柱塞式、叶片式和齿轮式中也有低速的结构型式，低速液压马达的主要特点是排量大、体积大转速低(有时可达每分钟几转甚至零点几转)、因此可直接与工作机构连接;不需要减速装置，使传动机构大为简化，通常低速液压马达输出转矩较大，所以又称为低速大转矩液压马达。

折叠低速马达
转速低于500r/min的液压马达属于低速液压马达。它的基本形式是径向柱塞式。低速液压马达的主要特点是:排量大，体积大，转速低，可以直接与工作机构连接，不需要减速装置，使传动机构大大简化，低速液压马达的输出扭矩较大，可达几千到几万Nm，因此又称为低速大扭矩液压马达。
