How To Solve The Problem of Rapid Wear of The Reciprocating Screw?

The rapid wear of the reciprocating screw is usually caused by poor lubrication, excessive load, installation deviation, foreign object intrusion, or material mismatch. To solve this problem, we need to start from the source and take targeted measures.

1. Optimize lubrication management

Insufficient lubrication is the main cause of rapid wear. Regularly use special lubricants (such as lithium-based grease or synthetic lubricants), avoid using ordinary grease. Based on the operating frequency, replenish once every 100–200 hours. If the environment is harsh or the operation is frequent, the cycle should be shortened. Ensure the grease is clean and free of impurities.

2. Improve operating conditions

Avoid long-term overloading or frequent start-stop of the equipment to prevent accelerated wear due to impact loads. Reasonably verify the load and screw specifications to ensure a proper match. For heavy-duty conditions, choose larger-diameter or high-load-grade screws.

3. Strengthen dust prevention and sealing

Foreign substances such as dust and metal chips entering the screw thread gap can cause abrasive wear. Install dust covers or telescopic protective sleeves, and regularly check if the sealing rings are intact to prevent contaminants from invading.

4. Standardize installation and alignment

During installation, ensure the coaxiality and parallelism between the screw and the motor and guide rail. The deviation should be controlled within 0.02mm/m to avoid local stress concentration and accelerated wear due to uneven loading.

5. Check and adjust the preload

Excessive preload increases friction and heat, while too little leads to gaps and impacts. Adjust the nut preload according to the equipment requirements to maintain smooth transmission.

6. Regular maintenance and replacement of wear-prone parts

For wear-prone components such as copper nuts, establish a regular inspection system. If you find thread wear, increased clearance, or abnormal operation sounds, replace them promptly to avoid cumulative damage to the screw.

7. Consider material and surface treatment

In harsh working conditions, you can choose surface hardening treatment (such as quenching) or coating screws to enhance wear resistance. If the environment is humid, prioritize using stainless steel material to prevent accelerated wear due to rusting.
