意大利CALZONI国内一级代理商
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**性能归功于其*特、具有**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。
液压马达亦称为油马达，主要应用于注塑机械、船舶、起扬机、工程机械、建筑机械、煤矿机械、矿山机械、冶金机械、船舶机械、石油化工、港口机械等。高速马达齿轮马达具有体积小、重量轻、结构简单、工艺性好、对油液的污染不敏感、耐冲击和惯性小等优点。缺点有扭矩脉动较大、效率较低、起动扭矩较小(仅为额定扭矩的60%--70%)和低速稳定性差等。

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、有单独外泄油口，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。

轴向柱塞泵除阀式配流外，其它形式原则上都可以作为液压马达用，即轴向柱塞泵和轴向柱塞马达是可逆的。轴向柱塞马达的工作原理为，配油盘和斜盘固定不动，马达轴与缸体相连接一起旋转。当压力油经配油盘的窗口进入缸体的柱塞孔时，柱塞在压力油作用下外伸，紧贴斜盘，斜盘对柱塞产生一个法向反力p，此力可分解为轴向分力及和垂直分力Q。Q与柱塞上液压力相平衡，而Q则使柱塞对缸体中心产生一个转矩，带动马达轴逆时针方向旋转。轴向柱塞马达产生的瞬时总转矩是脉动的。若改变马达压力油输入方向，则马达轴按顺时针方向旋转。斜盘倾角a的改变、即排量的变化，不仅影响马达的转矩，而且影响它的转速和转向。斜盘倾角越大，产生转矩越大，转速越低。轴向柱塞泵 E-A4VSO250EO2/30R-VPB25N00-SO3

折叠高速马达
额定转速**500r/min的马达属于高速马达。高速马达的基本形式有齿轮式、叶片式和轴向柱塞式。它们主要特点是转速高，转动惯量小，便于启动、制动、调速和换向。
