Reducing component wear is key to extending equipment lifespan, improving reliability, and lowering maintenance costs.

Correct Selection and Use of Lubricating Oil/Grease: Choose the appropriate lubricant: Select the suitable lubricating oil (viscosity grade) or grease (consistency, base oil, additives) based on the part type (bearings, gears, chains, etc.), working load, speed, temperature, and environment (humidity, dust, chemicals). Keep it clean: Ensure the lubricant is not contaminated by pollutants such as dust, moisture, or metal debris. Regularly replace or filter the lubricating oil and clean the grease fittings. Maintain the proper amount: Insufficient lubrication can lead to dry friction and severe wear; over-lubrication (especially for high-speed bearings) can cause churning heat generation, oil oxidation and deterioration, and energy loss. Follow the lubrication intervals and fill volumes recommended by the equipment manufacturer. Use the correct lubrication method: Manual oiling, automatic lubrication systems, oil bath, splash lubrication, etc.—choose the method suitable for the equipment and ensure proper lubrication coverage. Keep clean to prevent abrasive wear: Hard particles such as dust, grit, and metal chips are the main causes of abrasive wear. Use effective seals (oil seals, air seals, labyrinth seals) to prevent contaminants from entering the friction pairs, and regularly clean the equipment surfaces and surrounding environment, especially for open components or those exposed to harsh conditions. Ensure correct installation and alignment: Precise installation: Install parts (such as bearings, couplings, gears) strictly according to installation specifications and torque requirements. Improper installation (e.g., hammering the bearing inner ring into place) can cause immediate damage. Precise alignment: Ensure accurate alignment between rotating components (such as shafts and motors, or both ends of a coupling), including angular alignment and parallel alignment. Misalignment generates additional vibration and stress, leading to uneven wear and premature failure. Balancing: For high-speed rotating parts, ensure good dynamic balance to reduce additional loads and wear caused by vibration. Avoid overload and impact loads: Operate within rated conditions: Run the equipment within the load, speed, and temperature ranges specified by the manufacturer. Continuous overload significantly increases contact stress, accelerating fatigue wear and plastic deformation. Mitigate impacts: Avoid or reduce sudden starts, stops, and load impacts whenever possible. Impact loads can momentarily exceed design stresses, causing part fracture or crack initiation and accelerating subsequent wear. Use cushioning devices (such as shock absorbers or soft starters). Control operating temperature: Prevent overheating: Excessive temperatures reduce lubricating oil viscosity, weaken oil film strength, accelerate oil oxidation and deterioration, lower material strength, and can even cause scoring (adhesive wear). Ensure the cooling system (air cooling, water cooling, oil cooling) operates properly with adequate heat dissipation. Avoid excessive cold: At extremely low temperatures, lubricating oil may become too viscous with poor fluidity, resulting in poor lubrication during startup. In cold environments, select lubricants with good low-temperature performance or take preheating measures. Reduce or eliminate corrosion: Moisture and rust prevention: Moisture and corrosive media can cause chemical corrosion and electrochemical corrosion (rusting), damaging part surfaces, forming pits that become starting points for wear. Use rust-preventive oils/greases, improve equipment storage and working environments (control humidity), and select corrosion-resistant materials (such as stainless steel or surface-treated materials). Select compatible materials: In environments with corrosive media, choose friction pair materials that are mutually compatible and corrosion-resistant. Regular inspection and maintenance: Condition monitoring: Detect early signs of abnormal wear through vibration analysis, oil analysis (checking wear particles and oil degradation), temperature monitoring, and noise monitoring. Preventive maintenance: Regularly inspect, clean, lubricate, adjust, and replace wear parts according to a planned schedule—do not wait until parts completely fail before addressing issues. Timely repair: When parts are found to have excessive wear, damage (such as cracks or spalling), or excessive clearance, repair or replace them promptly to avoid "minor issues becoming major problems" and causing more severe secondary damage. Select appropriate mating materials: Friction compatibility: For contact pairs with relative motion (such as shaft and bearing, or gear meshing), select material combinations with good friction compatibility to reduce the tendency for adhesive wear. Hardness and wear resistance: Choose appropriate materials or surface treatments based on the type of wear. For abrasive wear-dominated conditions, increase hardness; for adhesive wear-dominated conditions, select incompatible materials or self-lubricating materials. Common practices include carburizing and quenching, nitriding, chrome plating, spraying wear-resistant coatings, or using engineering plastics and composite materials. Optimize design (if possible): Increase contact area: Where permitted, increase the load-bearing contact area to reduce pressure per unit area. Improve lubrication methods: Design reasonable oil grooves and oil holes to ensure lubricating oil can effectively reach friction surfaces. Use friction-reducing designs: Such as using rolling friction (bearings) instead of sliding friction, or using self-lubricating materials (graphite, PTFE composites), etc. Standardize operation: Train operators: Ensure operators understand the correct startup, running, and shutdown procedures for the equipment, avoiding improper operations (such as high-speed, heavy-load starts on cold equipment). Follow operating procedures: Strictly operate the equipment in accordance with the standard operating procedures. Summary of key points: Lubrication is the foundation, cleanliness is the guarantee, installation and alignment are the prerequisites, avoiding overload and impact is the priority, and monitoring and maintenance are the means. By integrating the above points into the daily management and maintenance processes of the equipment, you can significantly reduce part wear, extend equipment service life, and improve production efficiency and economic benefits.
