Features
- Low Friction Loss & High Transmission Efficiency: The many rolling balls between the screw shaft and the nut ensure a high level of motion efficiency. Compared to the sliding screw pairs of the past, the driving torque is reduced to less than 1/3, which is very helpful in saving energy.
- High Precision: The ball screw pair is produced using the world’s highest level of mechanical equipment. A strict control of temperature and humidity during the grinding, assembly, and inspection processes ensures high accuracy.
- High-speed Feeding and Micro-feeding: The ball screw pair utilizes rolling motion, ensuring precise micro-feeding due to the minimal starting torque, eliminating the crawling phenomenon often found in sliding motion.
- High Axial Rigidity: The ball screw pair can be preloaded to reduce axial clearance and achieve higher rigidity.
- Transmission Reversibility: The ball screw pair is not self-locking and exhibits transmission reversibility, which is a key feature for some applications.
Composition and Classification
The ball screw consists of a screw, a nut, steel balls, a pre-pressure piece, a reverser, and a dust guard. The ZLV SFS4005 3.175mm Quiet Heavy Duty Ball Screw falls under the silent type category, which incorporates special groove-shaped ball separators to suppress the noise generated by ball collisions, resulting in a quieter and smoother operation.
Parameters
- Nominal Diameter: The outer diameter of the screw, for the SFS4005, is 40 mm.
- Lead: The lead, or the linear distance the nut moves when the screw rotates one full revolution, is 5 mm for the SFS4005. The lead is related to the movement speed of the nut and the linear thrust that the ball screw can provide. A larger lead will result in a higher linear movement speed for a given rotational speed. The relationship between these parameters is given by v=r*i, where v is the movement speed of the nut, r is the rotational speed of the screw, and i is the lead.
- Length: The length refers to the overall length and thread length. The thread length includes the total length of the thread part, the effective stroke, the length of the nut, and the design margin.
- Nut Form: There are many types of nuts. They are generally classified by flange type (round flange, single-cut flange, double-cut flange, no flange), and by nut length (single nut and double nut). The ZLV SFS4005 uses a double nut, which has no load and rigidity difference but can adjust the preload.
- Accuracy: The ZLV SFS4005 follows the domestic standard with an accuracy grade of P1 to P10.
The ZLV SFS4005 3.175mm Quiet Heavy Duty Ball Screw, with its top-tier construction and features, provides an excellent solution for all your linear motion needs.
