Screw is a transmission element that converts rotary motion into linear motion and is widely used in various industrial equipment and precision instruments. Its main function is to convert rotary motion into linear motion, or torque into axial repetitive force, both high precision, reversibility and high efficiency.
Basic Structure of Screws
Screws are usually composed of the following parts:
Screw: the main part of the screw, the surface is machined with precision spiral groove.
Nut: cooperates with the screw to realize linear motion.
Steel ball: rolls between the screw and the nut to reduce friction and improve transmission efficiency.
Auxiliary parts such as pre-pressure piece, reverser, duster, etc. ensure the stable operation and long-term use of the screw 1.
Application fields of screw rod
Screws are widely used in the following fields due to their advantages of high precision, low noise and fast response:
Machine tool industry: used in the feeding system of machine tools to ensure high precision machining.
Automation equipment: In automated production lines, silk rods are used to precisely control the movement of robotic arms and workpieces.
Precision instruments: In scientific research and medical equipment, screws are used for high-precision positioning and adjustment 13.
Advantages of silk rod
High Precision: Screw drive has high positioning accuracy and is suitable for occasions that require precise control.
Low noise: Compared with other transmission methods, the noise generated by the screw drive is low.
High efficiency: high transmission efficiency due to low rolling friction.
Reversibility: it can easily realize linear motion in both positive and negative directions 12.
Motor shaft type classification introduction
I. Linear Shaft
Linear shafts are long shafts with a circular cross-section, which are mainly suitable for machines, equipment and tools that need to realize linear motion. Common linear shaft materials include steel, stainless steel, aluminum alloy and so on. Linear shafts are widely used in CNC machine tools, printing machines, packaging machines, elevators and other equipment.
Second, round shaft
Round shaft refers to the cross-sectional area of the shaft is round, commonly used in some need to rotate the machine equipment and tools. The material of round shaft can be steel, stainless steel, brass and so on. Round shafts are widely used in fans, electric motors, automobile engines, ships and other fields.
Third, square shaft
Square shafts are shafts with square or rectangular cross-sectional area and are used in machines, equipment and tools that require twisting or turning. Compared with round shafts, square shafts have higher torque and torsional hardness. Square shafts are widely used in hydraulic presses, punching machines, wire winches, transmission boxes and other components.
Four, hexagonal shaft
Hexagonal shaft is a kind of hexagonal cross-section of the shaft. It has many advantages, such as good torsional performance, transfer torque. Commonly used in drills, wrenches, screwdrivers and other hand-held tools, as well as automotive parts and other fields.
Five, shaped shaft
Shaped shaft refers to the irregular shape of the shaft, mainly used in some special occasions, such as tapered shaft, corrugated shaft and so on. Shaped shafts can be designed and processed according to the needs of the work, and are suitable for special machines, equipment and tools.
