Customized Auger Screw Flight for Precise Adjustment and Fixing in Precision Instruments

Spiral Screw Function

Transmission of Power and Motion:The screw shaft efficiently converts rotational motion into linear motion and torque into thrust through the engagement of the screw and nut. This conversion mechanism makes the screw shaft play a crucial role in mechanical transmission.

Force-transmitting Screw:Primarily used for transmitting power, it generates a large axial thrust with a relatively small torque. This type of screw is typically employed in situations requiring significant thrust, such as in screw jacks and screw presses. In these applications, the screw shaft can operate intermittently to produce sufficient thrust to lift heavy loads or overcome working resistance.

Motion-conducting Screw:Primarily used for transmitting motion, it is commonly found in applications requiring high-precision and high-speed transmission, such as the feed screw (lead screw) of machine tools. In these applications, the screw shaft ensures the stability and accuracy of the transmission.

Adjusting Screw:Used for adjusting and fixing the relative position between parts or components. This type of screw usually has a self-locking function to ensure stability at the adjusted position. For example, in the fine adjustment mechanisms of machines and precision instruments, the adjusting screw can precisely adjust the position of parts.

Spiral Screw Application

1.Agricultural Machinery: The screw shaft is primarily used for power transmission and material handling in agricultural machinery. For instance, in seeding machines and fertilizer applicators, the screw shaft can precisely control the seeding rate of seeds and the application rate of fertilizer, enabling automated and precise agricultural operations.

2.Material Handling Equipment: In material handling equipment, the screw shaft is mainly used for conveying and lifting materials. For example, on conveyor belts, the screw shaft can propel materials along a predetermined path, achieving continuous material conveyance.

3.Harvesters: In harvesters, the screw shaft is commonly used in the grain conveying and threshing processes. For instance, in the threshing drums of combine harvesters, the screw shaft can push grains into the threshing area while assisting the threshing drum in separating grains from stalks.

4.Grain Machinery: In grain processing machinery, the screw shaft is often used for grain conveying, mixing, and stirring. For example, in grain dryers, the screw shaft can convey wet grain to the drying area while assisting hot air in drying the grain.

5.Screw Conveyors: In screw conveyors, the screw shaft plays a role in propelling materials forward to achieve continuous material conveyance. Screw conveyors are widely used in various industrial fields such as chemicals, building materials, and food, for conveying powdered, granular, and other materials.
