Ball Screw Features
- Low Friction Loss, High Transmission Efficiency: The ball screw pair features a large number of rolling balls between the screw shaft and the screw nut, providing high transmission efficiency. This allows for drive torque to be less than one-third of that required by previous sliding screw pairs, aiding in energy conservation.
- High Precision: The ball screw pair is produced using state-of-the-art mechanical equipment, ensuring absolute precision. Strict controls over the production environment, including temperature and humidity, guarantee that product quality is maintained.
- High-Speed Feed and Micro Feed: The ball screw pair allows for high-speed feed and micro feed thanks to the use of rolling ball motion. The minimal starting torque avoids the creeping phenomenon seen in sliding motion, enabling precise micro feed.
- High Axial Rigidity: Preload can be applied to the ball screw pair, achieving high rigidity by reducing the axial clearance to negative values. This results in increased rigidity of the screw nut section due to repulsion forces on the ball.
- Non Self-Locking, Reversible Transmission: The ball screw pair cannot self-lock and has reversible transmission characteristics.
Ball Screw Composition and Classification
The ball screw consists of the screw, nut, steel ball, preload piece, reverser, and dustproof device. It can be classified as:
- Self-lubricating Ball Screw: This type of ball screw features a removable oil device and does not require a lubrication pipeline system or equipment, reducing oil replacement and waste oil handling costs.
- Quiet Ball Screw: This ball screw type features a special groove type ball spacer that can suppress the noise produced by the collision between the balls, making the ball screw smoother and quieter when moving.
- High-speed Ball Screw: Characterized by high acceleration, high rigidity, high-speed feed, low vibration, and low noise. It is used in the rapid feed of machine tools, high-speed cutting centers for grinding tools, and high-speed vertical load cutting centers.
- Heavy-duty Ball Screw: This can bear larger axial loads and is suitable for full-electric design machines, air compressors, semiconductor manufacturing devices, and forging manufacturing devices.
Parameters
- Nominal Diameter: The outer diameter of the screw. Common specifications are 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120 mm.
- Lead: This refers to the linear distance the nut moves when the screw rotates one round. The formula relating screw lead (i), screw rotation speed (r), and the nut’s moving speed (v) is: v = ri. Another relationship involves the screw thrust (F), the motor’s provided torque (T), transmission efficiency (n), and the screw lead: F = (2πTn) / i.
- Length: There are two concepts in length: the total length and the thread length. Some manufacturers only calculate the total length, but some require the thread length.
- Nut Form: There are several nut forms available, typically represented by the first few letters in the model number. Based on the flange form, there are circular flanges, single-cut flanges, double-cut flanges, and flangeless ones.
- Precision: Ball screws are graded in precision levels such as P1, P2, P3, P4, P5, P7, P10. Some regions adopt the JIS level (C0, C1, C2, C3, C5, C7, C10), and European countries use the IT grade.
The ZLV SFS1205 2.5mm Quiet Heavy Duty Ball Screw combines these characteristics and parameters to deliver a product that stands out in terms of quality, reliability, and performance. Whether it’s for small-scale applications or heavy-duty industrial use, this ball screw is engineered to deliver excellent results every time.
