The lead screw of the testing machine mainly regulates the test loading space.
Which testing machines are the lead screws mainly used in? Bojian testing machine manufacturers will answer for you: the lead screw is used in electronic universal testing machine, hydraulic universal testing machine, spring testing machine, tensile testing machine, pressure testing machine, torsion testing machine, fatigue testing machine.
What are the types of lead screws used in testing machines?
The lead screws used in the testing machine are divided into rolling lead screws and trapezoidal lead screws. When the lead screw is used as the active body, the nut will be converted into linear motion according to the lead of the corresponding specification with the rotation angle of the lead screw, and the passive workpiece can be connected by the nut seat and the nut to achieve the corresponding linear motion.
Advantages of rolling lead screw: small friction coefficient, low noise, fast rotation speed, easy control, high precision, long service life, so it is used in electronic universal testing machine, spring testing machine, tensile testing machine, pressure testing machine, torsion testing machine, fatigue testing machine, because these equipment need to rely on the lead screw precision transmission.

The trapezoidal lead screw relies on the oil film between the screw mother and the screw to produce a relative sliding work, and the sliding friction completes the linear movement.

The trapezoidal lead screw is used in hydraulic universal testing machines because it does not require very precise beam displacement and can take advantage of the self-locking of the T-screw.
