C-Spacer Design for Bearing Stability in X-Ray Tubes

The patent applies preliminary anti-action by designing the C-spacer with a specific thickness (0.5mm to 2.0mm) that proactively prevents tilting before it occurs. The C-spacer is positioned between the outer ring and outer ring spacer to preemptively counteract the thermal expansion effects that would cause clearance reduction and potential tilting at high temperatures, thereby maintaining bearing support stability without requiring preload adjustment.

The patent applies parameter changes by optimizing the C-spacer thickness within a specific range (0.5mm to 2.0mm). This parameter optimization balances two competing requirements: providing sufficient thickness to prevent C-spacer tilting and maintaining acceptable axial clearance between outer rings. The specific thickness range ensures that the C-spacer is stable enough to prevent tilting while not excessively increasing the axial clearance, thereby maintaining bearing performance.

The patent applies partial action by implementing a moderate contact condition between the C-spacer and outer ring spacer, rather than strong contact. The C-spacer thickness is designed to provide sufficient contact to maintain positional stability and prevent tilting, but not excessive contact that would complicate assembly or risk ball ejection. This balanced contact condition achieves the necessary positional fixation while keeping the assembly process simple and safe.
