The main problems existing in the development of coupling industry

Coupling the enterprise independent innovation ability is not strong is old problem facing the coupling industry for quite a long time, but with the rapid development of automobile, engineering machinery, etc, to form a complete set of coupling material, performance, the intensity of technical requirements and rise a new step, then, innovation ability this problem become more prominent. Our company specializes in the production of plum couplings


At present, the development trend of coupling products abroad mainly include the following aspects, first of all, the power transmission coupling system is developing along the direction of miniaturization, high speed, standardization, and the development of the application of special couplings, planetary coupling device, low vibration, low noise coupling device developed into design has some characteristics of the coupling; Second, due to the large-scale development of mechanical equipment, the working parameters of the coupling have been improved, such as the transmission power of the high-speed coupling is 1000-30000KW; Third, due to the wide application of hard tooth surface coupling, as well as the increasing number of high-speed and high-performance coupling requirements, so the requirements of grinding gear processing, efficiency and quality should be improved; In addition, with the development of self-facing coupling, people pay more and more attention to the material and heat treatment of coupling. According to Wang Shengtang, vice president of China coupling professional Association, at present, the products of China's coupling manufacturers in the fatigue life and noise index and foreign * level show a big gap, mainly with the material and heat treatment level has a great relationship.

However, most of the coupling manufacturers in Our country are basically unable to keep up with these trends, and can only repeat low-level construction and low-price competition in the low-end market. With the continuous upgrading of the automobile industry and machinery manufacturing industry, the low-end coupling market will soon be saturated, and then the business risk of enterprises will be greater. In addition, the supply risk of raw materials should also cause concern, on the one hand, although the domestic coupling steel market is stable, but the price shows a rising trend. On the other hand, the quality and performance of the coupling to improve the entry point in raw materials, the development trend of foreign coupling steel, one is low alloy steel containing Cr, Ni, Mo; The second is boron steel; The third is carbonitriding steel; The fourth is free cutting steel. However, the number of special steel enterprises that can provide high quality coupling steel in China is small, and it is expected that the competition for resources among enterprises will become more fierce in the future.
