For the problem of inflexible operation of the handle of the lighting exclusive hoist controller, solutions can be found from the aspect of lubrication. The specific methods are as follows:
Applying lubricating oil: After cleaning and derusting, it is necessary to scientifically select lubricating oil according to the differences in load characteristics and working environment of the components of the lighting exclusive hoist controller to ensure the lubrication effect. For moving parts such as connecting rods and rotating shafts that bear a certain amount of tension or torque for a long time, extreme pressure lithium-based grease (butter) is an ideal choice. It has excellent anti-wear performance and adhesion, and can form a tough and long-lasting oil film on the surface of the components. Even under the instantaneous impact force generated by frequent starts and stops, it is not easy to be squeezed off, effectively isolating direct metal contact. For small components such as precision transmission gears and micro-switch contacts inside the controller, special light mechanical lubricating oil (such as ISO VG32) should be selected. This type of oil has low viscosity and good fluidity, and can quickly penetrate into micron-level gaps, avoiding increased mechanical resistance due to excessively thick oil films, while reducing the impact on the sensitivity of precision components.
Precision should be emphasized in the application operation: For the connection part of the shaft pin and the shaft sleeve of the connecting rod, use a pointed oil gun to evenly inject grease along the axial direction, and rotate the connecting rod while injecting to ensure that the grease fills the matching gap until a small amount of grease overflows from the gap. For the spiral lines or tooth-like structures on the surface of the rotating shaft, dip a soft brush in lubricating oil and gently brush along the direction of the lines, repeating 2-3 times to ensure that the oil film evenly covers every concave and convex surface without liquid accumulation in the low-lying areas. If there are small scratches on the surface of the components of the lighting exclusive hoist controller caused by long-term friction, you can first let the lubricating oil fully soak the scratches for 3-5 minutes, use the fluidity of the grease to fill the tiny pits, and then perform regular application, which can significantly reduce the probability of jamming during friction.
