I. Basic Classification System for Timing Belt Tooth Profiles Before beginning identification, first understand the mainstream tooth profile systems: 1. Metric Trapezoidal Thread Series MXL: Finest pitch (2.032mm), micro transmission XL: Fine pitch (5.08mm), light load L: Medium pitch (9.525mm), general purpose H: Coarse pitch (12.7mm), heavy load XH/XXH: Extra coarse pitch (22.225/31.75mm), extra heavy…

Within the multi-layer composite structure of timing belts, the core functions like the skeletal framework of the human body, undertaking the core tasks of transmitting power, maintaining pitch stability, and withstanding operational tension. Selecting appropriate core materials and structures directly determines the transmission accuracy, service life, and reliability of the timing belt. This paper systematically…

In the realm of modern industrial transmission, timing belts serve as highly efficient and precise transmission components, widely applied in precision transmission systems such as automotive engines, machine tools, and textile machinery. Among the diverse family of timing belts, the “rubber-coated synchronous belt” stands out as a vital member. With its unique structural design and…

Signal for the aging and replacement of the timing belt

Price is superficial; performance is what truly matters. When a sudden timing belt failure halts an entire production line, or when reduced transmission precision turns products into substandard goods, you’ll realize: the initial savings on procurement costs have long been repaid tenfold through downtime losses and quality claims. Timing belts aren’t consumables—they are the “tendons”…
