Product Description

The ball screw rolling spline composite unit is a new type of composite rolling functional component developed for automation and intelligent production line applications. The product is widely used in mechanical combination devices such as horizontal multi joint robots (SCARA) Z-axis, dispensing machines, welding machines, automatic loaders, automatic detection equipment, and ATC (automatic tool change) in machining centers for rotational and linear motion. The product mainly consists of hollow screw spline shaft, ball nut rolling bearing composite unit, spline sleeve rolling bearing composite unit and other components.

Composite: Cross design the ball screw spiral raceway and the rolling spline (straight) raceway on the same shaft, and integrate the ball nut and spline sleeve with the rolling bearing height respectively. By rotating or stopping the ball nut and spline sleeve, the composite motion of the screw spline shaft can be achieved in three forms: rotation, straight line, and screw rotation. Lightweight and low inertia: The screw spline shaft adopts a hollow design, which is lightweight overall; The integrated design of the ball nut and spline sleeve with the bearing ensures that the radial dimensions of the ball nut rolling bearing composite unit and the spline sleeve rolling bearing composite unit are small enough, and the moment of inertia is extremely low. High speed, low noise: The ball screw adopts a large lead design, coupled with extremely low rotational inertia of the rotating unit, resulting in low noise during high-speed movement. Easy to install: The two end faces of the ball nut rolling bearing composite unit and the spline sleeve rolling bearing composite unit are equipped with standard driving pulley connection parts, which is convenient for users to choose and easy to install.
