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:
