  • The screw rod and screw rod look the same on the surface, but they are different in essence. I would like to introduce the screw rod and screw rod first, and then introduce their different design principles and uses, hoping to help you.


    Lead screw: It is a product that converts rotary motion into linear motion, or converts linear motion into rotary motion.


    Screw: a cylinder with spiral grooves on the outer surface of the screw or a cone with conical spiral grooves. The screw has different heads.


    1、 Different design principles:


    Screw rod: according to the national standard GB/T17587.3-1998 and application examples, it is used to convert the rotating motion into linear motion; Or it can convert linear motion into rotary motion, with high transmission efficiency and accurate positioning.


    Screw: The main part of the pin screw is a common screw. The pin can be set in the melting section of the screw or the falling groove of the metering section or on the smooth cylindrical surface without a screw groove at the end of the metering section. The pins shall be arranged according to the corresponding arrangement, with different density and quantity.


    2、 Different uses:


    Screw rod: to adapt to different uses, a wide range of standardized products are provided. Applied to machine tools.

    Screw: mainly used for plastic molding equipment, such as plastic profile extruder, injection molding machine, etc.
