在ELEKTRO ROUND直流油缸中,活塞杆的向前运动是通过顶点螺钉和自润滑技术聚合物螺母获得的。该活塞有一个导向环,经过校准,以尽量减少与气缸套的间隙,并减少螺杆旋转期间的振动。活塞还配有磁铁,用于磁传感器。该系统由直流电机驱动,有两个版本,12和24VDC。电机的位置可以使用可选的编码器控制。可在气缸中插入可复位的可选保险丝,用于电机热过载保护。所使用的电机有一个行星变速箱与1 /13或1 /25的比率。根据配置(螺杆节距和传动比),该气缸可以是不可逆的(在电机关闭的情况下支持负载)或负载下可逆的。两种型号均不提供活塞杆防旋转装置,由客户在缸外提供。它有两种版本:-与直列电机,其中电机轴通过联轴器直接连接到螺杆。 - with a geared motor, where the transmission of motion is ensured by three cogwheels with a ratio of 1:1. This cylinder is designed for use with IP65 protection rating.The solutions with the trapezoidal screw (acme) are generally suitable for applications where the number of operations per time unit is reduced; the degree of accuracy is not particularly high due to heating of the screw-leadscrew assembly; wear over time does not create inconveniences, no high forces and speeds are required at the same time.
