Υψηλή ακρίβεια γραμμική σφαίρα Spline

The ball spline uses the balls installed in the outer cylinder of the spline shaft to smoothly roll and transmit torque in the precision ground rolling groove. It adopts a unique contact point design and has a larger contact angle (40°) In addition to high sensitivity, it can also greatly increase the load capacity. It is suitable for environments with excessive vibration and shock loads, high positioning accuracy requirements, and high-speed motion performance. It can also play an effective role in this type of environment. . At the same time, even when used instead of linear ball bushings, the rated load of the ball spline is ten times that of linear bushings under the same shaft diameter, so the design can be made very compact, even in the case of cantilever load, It can be used safely and has high durability even under the action of torque.

High Precision Linear Ball Spline, designed and produced by our own brand WKT, widely used in automation field. High Precision Linear Ball Spline also called a ball bearing splines, recirculating ball spline, consist of screw spline and a nut integrated with balls and balls' return mechanism, return tubes or return caps. Precision ball spline nut is Floating deflector cycle mode, and the nut shape is round nut with flange.

Χαρακτηριστικά:
(1) Lead Accuracy Up to Grade C3 C5 C7 and C10 ,screws have been Standardized. C5 on request.
(2) Precision Ground Ball Nut High Precision Ball Nut are interchangeable between ground and rolled screws.
(3) Available to ship separately ball screw and ball nuts can be shipped separated ensure shortest delivery time. The ball nuts are standardized with light preload, also the preload value can be adjusted to zero or heavy.

High Precision Linear Ball Spline, we make full use of features of Miniature Ball screw manufacture and super compact design actuator can achieved the high precision C3 according to our customers' requirement. The diameter of one of the screw shaft ends must be less than the screw shaft root diameter, otherwise ball nut cannot be installed.
For Application field, High Precision Linear Ball Spline also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing.Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack.

Ball spline structure
Ball splines can be divided into two types: SLF with flange type and SLT without flange. Due to the size of the shaft diameter, the contact path of the steel ball can be divided into 2 rows (180°) (SLF/SLT6 ~ 20) and 4 rows (70°)(SLF/SLT25 ~ 50), in addition, hollow shafts are also available for selection.
High Precision Linear Ball Spline ，The ball spline is equipped with 3 rows of load steel balls on the outer diameter of the spline shaft, and adopts the Gothic design so that the 3 rows of steel balls can bear both clockwise and counterclockwise torque at the same time to increase the service life and rigidity. Each row of steel balls continuously circulates the entire row through a special synthetic resin circulator installed in the spline cap. Therefore, even if the spline shaft is extracted from the spline cap, the steel balls will not fall off.
