液压马达是液压系统的一种执行元件,它将液压泵提供的液体压力能转变为其输出轴的机械能(转矩和转速)。液体是传递力和运动的介质。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。
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。

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。

CALZONI、CALZONI马达、CALZONI电机、 CALZONI液压马达、CALZONI径向柱塞液压马达
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。一系列的新颖设计对于马达重量的减少与外形尺寸的优化具有重要的意义,特别是相对于相同排量的传统液压马达来说,优势明显。系统时序是通过旋转阀(5)来实现的,阀通过连接在旋转轴上的旋转阀驱动轴(8)驱动。旋转阀在旋转阀芯(6)与固定在马达壳体上的反应环(7)之间旋转。系统时序也是**设计,可以达到压力平衡及温度的自补偿。此阀的优点是具有革命性的油缸排列,实现较高的机械与容积效率。扭矩输出即使在低速下也是相当平稳,即使在负载下马达也表现出高性能的启动特性。CALZONI 液压马达MRCN、 MRC、MR系列。意大利CALZONI主要产品包括:马达、CALZONI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。
