Features of Ball Screws

  1. Low Friction Loss, High Transmission Efficiency: Thanks to the rolling movement of many balls between the screw shaft and nut, a high transmission efficiency is achieved. Compared to sliding screw assemblies, the drive torque is reduced to less than 1/3, which contributes significantly to power saving.
  2. High Precision: The ZLV SFS2005 Ball Screw is produced with the highest precision mechanical equipment available. Strict controls over temperature and humidity during the grinding, assembly, and inspection processes ensure the highest levels of precision.
  3. Fast Feed and Micro Feed Possible: As the ball screw uses rolling motion, the starting torque is minimal, eliminating the creeping phenomenon observed in sliding movements. This ensures precise micro-feeding.
  4. High Axial Rigidity: The ball screw can apply preload, reducing the axial gap to a negative value and thereby increasing rigidity.
  5. Non-self-locking, Reversible Transmission: The ball screw can’t self-lock, ensuring the possibility of reversible transmission.

Ball Screw Components and Classification

A ball screw comprises the screw, nut, steel ball, preload piece, reverser, and dust-proof device. The ZLV SFS2005 Ball Screw falls under the Quiet Heavy Duty category, characterized by low noise and high load-bearing capabilities.

Parameters

  1. Nominal Diameter: The outer diameter of the screw, in this case, 20mm.
  2. Lead: The distance the nut moves linearly when the screw rotates one full turn, which is 5mm for this model.
  3. Length: Consists of two concepts – total length and thread length. Both are customizable based on client requirements.
  4. Nut Shape: Comes in multiple forms for different applications. The SFS2005 model uses the M6 form.
  5. Precision: The ZLV SFS2005 Ball Screw boasts high precision levels suitable for a wide range of applications.

Calculation of Nut Speed and Screw Thrust

Nut speed (v) and screw thrust (F) are crucial parameters for understanding the performance of a ball screw. These can be calculated as follows:

v = r*i

  • v: Nut movement speed (mm/s)
  • r: Screw rotation speed (r/s)
  • i: Lead (mm)

F = (2πT*n)/i

  • F: Screw thrust (N)
  • T: Torque provided by the motor (N·m)
  • n: Transmission efficiency (generally 85%-95% for ball screws)
  • i: Lead (m)

Customization

As per customer needs, the ZLV SFS2005 Ball Screw can be tailored to fit specific application requirements, encompassing factors like the length, nut shape, and precision.

Conclusion

The ZLV SFS2005 3.175mm Quiet Heavy Duty Ball Screw offers a robust solution for applications demanding high transmission efficiency, low noise, and precise motion control. With customizable features, it offers the flexibility to match your unique operational requirements. Leveraging these advantageous attributes, ZLV ensures the provision of high-quality, reliable, and efficient mechanical components.
