Abstract
Abstract This paper studies the influence of bearing speed under a self-lubricating system. In the early 20th century, specialized precision manufacturing companies were founded, further establishing ball bearings as a very valuable, high-quality, and easily accessible mechanical component. This study used a self-lubricating system to achieve constant temperature and precision control. The spindle speed was analysed and tested at three speeds under a fixed pre-loading of 13000 N and a fixed lubricating oil viscosity index of 15. The results showed the spindle speed increases, the heat generated increases, and internal component temperature changes also increase. When the spindle speed is 12,000 rpm, the temperature of the inner ring of the bearing increases and changes by 166.4 %, causing fatigue and scratch wear at the same time. Using a lubricating oil self-lubricating system can slow down the temperature rise rate of components. The operation system can quickly reach a stable state, reducing thermal deformation and temperature accuracy errors.
