Factors causing damage to ball spline shaft

After a certain period of use, the ball spline shaft will always fail or be damaged. Analyzing the damage situation and adopting corresponding measures can improve its service life and operational reliability, reduce the frequency and cost of host maintenance, and extend the host's service life. The main factors causing damage to Dongguan ball spline shafts are as follows for your reference:
1. Damage caused by overload
Under good sealing conditions, overload is often one of the main factors causing damage to the imported ball spline shaft. Overloading can cause premature fatigue of the ball roller axis data and fragmentation and peeling of the outer layer data of the raceway. At the beginning, it occurs on a small area, but spreads rapidly. When continuously used, the phenomenon of fragmentation and peeling will expand to the outer surfaces of the inner and outer raceways and steel balls. Generally, damage caused by overload starts from the inner ring, and the trajectory of the steel ball on the raceway is particularly wide.
2. Damage caused by poor alignment
Poor alignment has a significant impact on imported ball spline shafts. When the steel ball is not centered or perpendicular, it will squeeze into the edge of the raceway, causing the rolling trajectory of the steel ball to be skewed. Excessive skewness can cause damage to the persistence frame.
3. Damage to the ball spline caused by overheating
Overheating caused by lubricants, such as lubricant degradation or contamination, excessive lubricant can also cause overheating; Overripening caused by overload; Due to improper installation, the persistence frame heats up; Because of the heat conducted in by external heat sources. If the ball spline shaft is overheated for a long time, it will cause discoloration on the surface. Dongguan ball spline manufacturers believe that the smoothness is generally insufficient or the quality of the smoothing agent is poor. Imported ball spline shafts will appear dark blue or blue black on the surface. Overheating has a significant impact on the normal operation of ball spline shafts, and it is necessary to correct it in a timely manner.
4. Overly tight and damaged during installation and rolling
If the imported ball spline shaft is pressed against an overly tight journal, it may cause the inner ring to swell, or perhaps the small aperture of the ball spline shaft seat may cause the outer ring to shorten, resulting in radial compression, or perhaps one ball spline shaft may be tightly pressed against another, causing axial compression.
