Critical speed of ball spline

Critical speed of ball spline
When the ball spline shaft in use is rotating, resonance will occur when the rotational speed approaches the critical speed that affects the spline shaft. Therefore, the maximum number of rotations must be limited to below the critical speed and to the extent that resonance does not occur. The critical speed can be calculated. For safety reasons, please multiply it by a safety factor of 0.8.
Ball splines are used to transmit torque and provide guidance
Ball spline pair is a linear motion system, which can transmit torque when the spline sleeve uses the steel balls in it to move linearly on the precision ground spline shaft. The spline pair has a compact structure, which can transmit excess loads and power, and has a longer lifespan.
Spline pairs can be divided into three types: flange type spline pairs, groove type spline pairs, and end cap type spline pairs. Usually, the radial load and transmitted torque of the flange type spline pair are greater than the other two types.

The spline pair has a compact structure, which can transmit excess loads and power, and has a longer lifespan.
Spline pairs can be divided into three categories:
There are three types of spline pairs: flange type spline pair, groove type spline pair, and end cap type spline pair.
Under normal circumstances, the radial load and torque transmitted by the flange type spline pair are greater than those of the ball spline, which is composed of a screw cap and a shaft. The balls contained in the screw cap move linearly along the precision ground keyway, and can transmit torque in the circumferential direction of the shaft in a linear motion system There is also a screw cap that can be used to achieve high performance in areas with full load in the radial direction and vibration impact, requiring high positioning accuracy or high-speed movement He's bigger than the other two.
