End Cap Ball Screw
End Cap Ball Screw
End cap ball screw are transmission devices that achieve ball circulation through an end-cap structure. Their core features are compact design and low noise performance. The following is a detailed explanation of their working principle, structural characteristics, and typical applications:
End Cap Ball Screw Working Principle: End-cap ball screws form a ball circulation channel through the engagement of the screw, nut, and helical grooves on the end cap. When the screw rotates, the balls circulate within the channel, converting rotational motion into linear motion.
Compared to tube-type or groove-type screws, the end-cap type uses a rolling design at the junction of the return hole and the end cap. Although the steeper slope may increase friction loss, it effectively reduces noise during high-speed operation.
Product Details
End Cap Ball Screw Structural Features:
1. Compact Design: The nut is smaller than that of the tube-type ball screw, suitable for space-constrained installation environments.
2. Noise Performance: The balls circulate within the nut and between the end cap, maintaining low noise even at high speeds.
3. Precision Grooves: Utilizing a Gothic groove shape, the clearance between the balls and the grooves is extremely small. Pre-tensioning enables backlash-free transmission, improving rigidity and positioning accuracy.
4. Sealing and Protection: Equipped with sealing gaskets and contact-type sealing rings, effectively preventing dust and foreign matter from entering and extending service life.
End Cap Ball Screw Application:
End-cap type ballscrews are particularly suitable for applications requiring high precision and low noise.
1. Precision machine tool feed systems
2. Linear drive components in medical equipment
3. Precision positioning modules in automated equipment
End Cap Ballscrew Installation
Installation Methods: Common support methods include one-end fixed and one-end floating, and both ends fixed and pre-tensioned, etc. The appropriate method must be selected based on the screw length and precision requirements.
Maintenance Points
Maintenance Recommendations: Regularly check the condition of the sealing rings to avoid excessive lubrication affecting performance and ensure the ball circulation channels are clean.
