The function and main use of stainless steel helical inserts for particle-free environments

The role of the stainless steel helical inserts for particle-free environments

Stainless steel helical inserts for particle-free environments are a new connection fastening technology. It can effectively improve the connection conditions and significantly improve the reliability of threaded connections. Its advantages are as follows:

1. Stainless steel helical inserts for particle-free environments are used for various low-strength materials. They can significantly improve the wear resistance of threaded connections and avoid damage.

2. The stainless steel helical inserts for particle-free environments have a certain elasticity. It can make the load distribution on each circle of the thread more uniform, eliminate the pitch and tooth shape deviation between the screw and the screw hole, and absorb vibration, to improve the connection strength and fatigue strength of the thread.

3. The locking type stainless steel helical inserts for particle-free environments can lock the screw in the threaded hole. Prevents the screw from loosening when it is subjected to shock vibration and has better process performance than the usual locking device.

4. Compared with the method of burying steel or copper bushing, under the same strength conditions, smaller size and higher strength screws can be selected, which can reduce the volume and weight.

5. The hardness of the stainless steel helical inserts for particle-free environments is higher than that of the screw, so it is less worn during the connection with the screw. It can be reused. According to the relevant experimental research, the tensile strength of the stainless steel helical inserts for particle-free environments is more than seven times that of the screw. If the screw breaks, the wire screw sleeve will not be damaged.

The primary use of stainless steel helical inserts for particle-free environments

1. Enhance connection strength and improve connection conditions. Steel wire sheath selection of aluminum, magnesium, and other low-strength materials. It can avoid thread slip—tooth dislocation phenomenon. Obtain excellent connection performance.

2. Wear resistance. Frequently removed parts can significantly improve the service life of the thread.

3. Increase the force surface for parts that require a strong connection but cannot increase the hole diameter.

4. Lock, especially for spacecraft and other products requiring high safety.

5. Easy to maintain. Install the damaged screw hole into the stainless steel helical inserts for particle-free environments, which can be used again after repair to avoid the possibility of reporting damage to the workpiece.
