In the 1980s, the world’s gear technology developed very rapidly. The general trend of product development is miniaturization, high speed, low noise, and high reliability. One of the most striking aspects of technological development is electrical branching technology and modular design of hard tooth surfaces. Apart from that, you should check out the recommended มอเตอร์เกียร์ FKT as well.
In the 1980s, foreign hard surface gear technology became more and more mature. Adopting high-quality carburizing wrought alloy steel and quenching hard tooth grinding surface, precision not lower than ISO1328-1975 level 6, the comprehensive carrying capacity of hard teeth and tempering teeth 4 times, for 5 ~ 6 times the surface of dental soft teeth. A medium sized hard gear reducer weighs only about one-third of the gear reducer. Branch power technology, which mainly refers to the power of the planet and the strength of large and multi-branch devices, such as the main driver of the main cement factory.
Modular design technology, universal gear reducer and standard to point to the pursuit of high performance and diversification of large coverage to meet user needs at the same time, minimize the empty parts specifications, to organize production, to form batch production parts, to reduce costs, and to achieve better economic value.
The application and maturation of this technology make the performance ratio of gear products increase rapidly, and the products are increasingly perfect.
From the 1970s to the early 1990s, Chinese high-speed gear technology experienced three stages: the introduction of technology, imitation mapping, and technological breakthroughs for independent design and manufacturing. At present, the design and production capacity of our own country can basically meet domestic production needs, and the highest parameters designed and produced are maximum power of 44MW, the maximum linear speed of 168m / s, the maximum speed of 6700r / min.
China’s low-speed heavy duty gear technology, especially hard tooth surface technology, has also undergone a mapping and imitation phase, which has been developed in stages from the start. Apart from understanding manufacturing technology, in the late 1980s and early 1990s, we also carried out a series of tasks such as “broken shafts” and “selection”. In the 1980s, it was considered that cement milling and rolling mechanical dampers, which were the two main problems in domestic heavy-duty equipment, could be completely solved.
