Product Description
Introduction:
A ball spline is a linear, rotating device that crosses a ball screw groove and a ball spline groove on a shaft. And special support bearings are directly mounted on the nut outer circle of the ball screw and ball spline respectively. By making nuts and splines rotate or stop, only one shaft can carry out three forms of motion (rotation, straight line and spiral). The ball spline shaft rotation motion stops because the rotation of the spline shaft becomes higher and resonates close to the fixed frequency of the spline shaft. Therefore, the maximum number of revolutions is controlled by limiting the degree to which no resonance is generated. When used beyond the resonance point, or near the resonance point, it is necessary to explore the diameter of the spline shaft.
Ball spline is the use of the ball installed in the spline outer cylinder, in the rolling groove of precision grinding, one side for smooth rolling, one side for transferring torque, is an epoch-making linear motion system. Moreover, unlike the traditional construction, because a single spline outer cylinder can be pre-pressed, it can play an effective role in places where the vibration impact load is too large, where the positioning accuracy is high, and where high-speed motion performance is required. At the same time, even if it is used instead of linear ball bushing, the rated load of the ball spline is more than ten times that of the linear ball bushing in the case of the same shaft diameter, so the design can be very small. Even in the case of cantilever load, torque, etc., it can be used safely and has a long life.
Advantages of ball splines:
1.Large load capacity: the rolling groove of the ball is precision grinding molding, and the Gode type 40° Angle contact is used, because of the large contact Angle, it has a large load capacity in the radial and torque direction. 2.Zero clearance in the direction of rotation: The spline shaft is combined with the spline outer cylinder by using a relative 2 to 4 row of ball rows with a contact Angle of 40°, and the clearance in the direction of rotation can be zero by adjusting the prepressing mode. 3.High sensitivity: Due to the special design of the steel ball contact point, in addition to high rigidity, it is more sensitive and can reduce energy waste. 4.High rigidity: Due to the large contact Angle, it has high rigidity, and the appropriate pre-pressure can be applied according to the situation, so it can obtain high torque rigidity and torque rigidity. 5.Simple assembly: Due to the special design, the steel ball will not fall off even if the spline outer cylinder is detached from the spline shaft. Therefore, assembly, maintenance and inspection are easy to carry out. Advantages of rotating series (one-piece) components
