Product Description

The main drive of the ball nut is a revolution in the form of ball screw auxiliary drive. In the fields of long stroke, heavy load, and high-speed transmission, the rotating nut combination unit will be your first Product selection

Characteristics of rotating nut combination unit: Low inertia: Compared to using screw rotation as the active drive, using nut rotation as the active drive greatly reduces the rotational inertia of the mechanical motion system, increases the maximum speed of the system, facilitates high-speed transmission, and reduces the selected motor power. High stiffness: Compared to the active driving method of screw rotation, the bearing size specifications arranged on the outer circle of the nut are larger; At the same time, because the screw does not rotate, there is no need to install bearings on its shaft neck, which can apply greater axial pre tension force to the screw, greatly improving the stiffness of the entire ball screw pair

Multi nut drive: Multiple rotating nut combination units can be installed on a ball screw, and multiple workbenches can be driven simultaneously or separately, with their movements not interfering with each other. Easy design and installation: The rotating nut combination unit integrates multiple functional components, simplifying design and facilitating installation and debugging. Other: Due to the non rotation of the screw, there is no circumferential friction at the middle auxiliary support, and there is no local heating problem; When the positioning accuracy is high and the influence of temperature rise is considered and a hollow cooling structure with a screw is adopted, the cooling pipe joint is easier to arrange and install because the screw does not rotate.
