The Spring Festival, also known as the Lunar New Year, is the central family reunion holiday for Chinese people, much like Christmas in the West. During this festive period, people engage in a series of vibrant traditional activities: • Posting Spring Festival couplets and “Fu” characters: Red couplets and upside-down “Fu” characters are displayed on…
In the realm of industrial transmission, timing belts serve as core components for precise power and motion transfer, their value long transcending simple “transmission.” In recent years, a seemingly minor yet critically important secondary processing technique—precision hole punching for timing belts—has quietly emerged as an invisible engine driving industrial upgrading. By machining holes of specific…
In the realm of precision transmission, PU timing belts have become core transmission components in automation equipment and precision instruments due to their outstanding wear resistance, high elasticity, and oil resistance. However, a frequently overlooked yet crucial design detail the tooth profile silently governs the overall physical properties of the timing belt. From classic trapezoidal…
The evolution of timing belt tooth profiles is fundamentally a continuous optimization of their physical properties. Different tooth designs directly determine the belt’s performance in mechanical, acoustic, and tribological aspects. Understanding these physical property differences is essential for making scientifically sound selection decisions. I. Comparative Analysis of Core Physical Properties of Timing Belts 1. Stress…
