The advantages of rotary ball screw spline are discussed

With the increase of industrial technology and automation capacity, more and more enterprises begin to enter the field of intelligence. Especially in SCARA robot configuration, it is widely used. With the popularity of 3C digital electronic products and equipment, the demand in this area generally increases, resulting in excessive demand, sometimes in short supply. Today we are talking about the components used in SCARA robot. Let's follow the steps of our technical engineers in Dongguan Sisk to discuss the excellent performance of rotary ball screw spline. Those who are interested may wish to have a look!

First, structure and specialty

The nut rotary ball screw is equipped with a special bearing sleeve on the outer diameter of the nut to make it operate. By rotating or stopping the nut, only one shaft can carry out two kinds of (rotating and spiral) model movements. The rotary ball spline is equipped with a special bearing sleeve on the outer diameter of the spline outer cylinder to make it operate. By rotating or stopping the outer cylinder, only one shaft can carry out two (rotating and linear) modes of motion. The rotary ball screw spline can rotate or stop the nut / outer cylinder, and can move in three modes (rotation, screw and straight line) with only one shaft. It is suitable for horizontal multi joint manipulator (SCARA), industrial robot, automatic loader, laser processing machine, handling device, ATC device of machining center, etc. it is most suitable for combined device of rotary motion and linear motion.

Second, zero clearance in spline rotation direction / high positioning accuracy

The contact angle between the spline outer cylinder and the steel ball is 45 °, and the bearing DF (face-to-face combination) design can absorb the error during assembly, automatically adjust the concentricity, and can bear large axial load and high-precision assembly.

Third, high speed / smooth operation

The rotating series screws are designed with high lead, which can move smoothly at high speed.

Fourth, low noise / high rigidity

Through high-precision grinding technology, the steel ball can smoothly walk along the tangent direction in the nut, reduce the noise and friction caused by blocking, and improve the rigidity and service life.

Fifth, easy installation / space saving

The nut is integrated with the bearing sleeve. During assembly, only the screw and the bearing sleeve need to be locked on the support seat, which is very simple. The nut is integrally formed with the bearing sleeve, with small volume and large assembly space.

Through the above detailed explanation of our technical engineers, you must have a certain understanding of the excellent performance of rotary ball screw spline. Especially for this important element moving part, of course, you can call us at any time to contact us if you encounter any unclear places in the process of future use.
