Optimizing lubrication in circular knitting machines enhances performance, reduces wear, extends lifespan, and improves production efficiency and fabric quality.

Abstract

Objective: This study investigates the lubrication system of circular knitting machines, aiming to optimize lubricant usage for enhanced performance and longevity of machine components. The primary objectives were to determine the appropriate quantity of lubricating oil required for different types of circular knitting machines and to elucidate the lubrication mechanisms involved. Methods: It involved gathering raw data on machine parameters, fabric characteristics, and production metrics from various circular knitting machines. Experimental setups included measuring oil viscosity, friction coefficients, and wear rates under controlled conditions. Standardized testing protocols were employed to ensure consistency across experiments. Results:  It indicated that the optimal quantity of lubricating oil varies depending on machine type and operational conditions. By correlating machine parameters with lubricant usage, it was found that precise oil application significantly reduces frictional losses and wear on critical components such as cylinders, needles, and sinkers. Analysis of fabric quality and production efficiency metrics revealed that effective lubrication enhances operational reliability and output consistency. Conclusion: Understanding the lubrication system of circular knitting machines is crucial for maintaining their performance and extending their service life. This research underscores the importance of tailored lubrication strategies tailored to specific machine types and operational environments. Future studies could explore advanced lubricants or alternative lubrication techniques to improve machine efficiency and durability further.
