KTOMOTION Ball Spline Structure and Advantages

manufacturers are choosing intelligent manufacturing. Especially in recent years, the sales of four axis robotic arms and single axis robots have been astonishing. Therefore, how to distinguish and judge the increasing demand for moving parts? The structure and advantages of KTOMOTION ball spline.
Firstly, understand the KTOMOTION ball spline
KTOMOTION ball spline uses balls installed in the outer cylinder of the spline shaft to smooth the transmission torque of the rolling mill in the precision grinding and rolling groove. Adopting a unique contact point design, the contact angle is larger (40 °). In addition to high sensitivity, it can also greatly enhance accountability. It is suitable for environments with excessive vibration and impact loads, high positioning accuracy, and the need for high-speed motion performance, and can also play an effective role in such environments. Meanwhile, even when replacing the linear ball sleeve, due to the same shaft diameter, the rated load of the KTOMOTION ball spline is more than ten times that of the linear rail sleeve. Even under the action of cantilever load and torque, it can be used safely and has high durability.
Secondly, understand the structure of KTOMOTION ball spline
KTOMOTION ball splines can be divided into five types: circular flange SLF type, cylindrical SLT type, enhanced dust-proof SZF type, Fabry Perot SOF type, and cylindrical SOT type. Due to the size of the shaft diameter, the contact path of the steel ball can be divided into two rows (180 °) and four rows (70 °). In addition, hollow shafts are also available for selection.
Thirdly, the advantages of KTOMOTION ball spline
1. Large carrying capacity
The ball rolling groove is precision ground and formed, using Goethe style 40 ° angular contact. Due to its large contact angle, it has a high load-bearing capacity in both radial and torque directions;
2. Zero clearance in the direction of rotation
The spline and spline outer cylinder are combined with 2-4 rows of ball bearings with a contact angle of 40 °, and the clearance in the rotation direction can be adjusted to zero by adjusting the preload force;
3. High sensitivity
Due to the special design of the steel ball contact point, in addition to high stiffness, it is more sensitive and can reduce capacity waste;
4. High stiffness
Due to the large contact angle, it has high stiffness and can be preloaded appropriately according to the situation, thus achieving high torque stiffness and torque stiffness;
5. Easy assembly
Due to the special design, the spline outer cylinder can be separated from the spline shaft in a timely manner, and the steel ball will not fall off. Therefore, assembly, maintenance, and inspection are all easy.
