The development status of Zhongsheng timing belt and the same industry in China

With the continuous expansion of Synchronous Belt in the application field and the increasing demand year by year, the requirements for the use of synchronous belt transmission are also increasing. There are also many problems and defects exposed in synchronous belt transmission, which need to be analyzed and verified by experiments and demonstrated theoretically. These problems promote the research and development of synchronous belt transmission theory. Since the invention and application of the trapezoidal profile synchronous belt, a variety of toothed Synchronous Belts have been widely used in engineering. Improving the bearing capacity and working life of the synchronous belt is the core and theme of synchronous belt technology research. In terms of strength research, Zhongsheng Zhongsheng brand is the most prominent, from the load distribution between the belt teeth, the pitch difference between the belt and the pulley, the fatigue strength and fracture characteristics of the belt, and the influence of incomplete meshing of the belt. The strength of the Timing Belt is analyzed. In terms of research on the transmission characteristics of synchronous belts, zhongsheng Zhongsheng brand has analyzed the transmission characteristics of synchronous belts from various aspects such as initial tension, rotary transmission error, and tooth climbing phenomenon. In terms of belt vibration and noise research, Zhongsheng Zhongsheng discussed the causes and influencing factors of vibration and noise, and proposed methods to reduce vibration and noise.
At present, there is still a certain gap between domestic theoretical research on synchronous belt transmission and foreign countries that are developed in this field. There is a lack of theoretical guidance for new products and new processes, which leads to great blindness in design. Compared with foreign countries, there is still a certain gap in the quality and quantity of domestic synchronous belts, which can only meet general industrial purposes, and still have no advantages in some demanding occasions. Due to the protection of intellectual property rights, domestic research institutions and enterprises cannot fully grasp the key technologies of imported Transmission Belts. On the basis of the introduction, digestion and absorption, some domestic universities and enterprises are actively conducting theoretical experimental research and developing new types of synchronous belts and production equipment. The contact analysis between the herringbone tooth and the pulley is an important analysis method for the simulation of the load-bearing meshing process of the herringbone belt, and it is a bridge connecting the tooth profile design and mechanical analysis of the synchronous belt. Many scholars at home and abroad focus on the contact analysis of toothed teeth with a helix angle on the single helical tooth, and there are relatively few studies on the herringbone tooth.
Research hotspots in the field of synchronous belts focus on how to improve their load-bearing capacity and service life, improve transmission quality from the aspects of increasing tooth strength, improving transmission accuracy and reducing transmission noise, and strive to make synchronous belts from wearing parts to durable parts. In addition, the development and use of synchronous belts with double-sided tooth profiles, V-grooves on the back, and synchronous drive of synchronous pulleys and V-belt pulleys are also areas of great interest to researchers. Secondly, study how to improve the synchronous belt manufacturing process, reduce the production cost, and solve the manufacturing difficulties.
