The main manufacturers are Jingzhou Giant Whale Machinery Co., Ltd., Luoyang Zhongzhong Gears Co., Ltd., Xi'an Heavy Machinery Research Institute, and Shijiazhuang Branch. Heavy Industry Co., Ltd., Inner Mongolia Xinghua Machinery Factory.
In the development of various kinds of special-purpose transmission machine manufacturing, the domestic has made significant progress in recent years, such as the MDH28 mill edge drive transmission device produced by Chongqing Gearbox Co., Ltd., its maximum power has reached 7000KW, transmission torque Up to 5000KN.m, with a total weight of 46 tons, the maximum module of the 1700 hot continuous rolling main transmission gear box produced is 30, and the weight is 180 tons. The gwc70/76 type 12,000 tons and marine gearbox produced by Hangzhou Advance Gearbox Co., Ltd. have a transmission power of 6250KW. The maximum power of the series of gearboxes produced by Nanjing Gaoqin Gear Co., Ltd. and Chongqing Gearbox Co., Ltd. has reached 3,800 KW. It was developed by Xi'an Heavy Machinery Research Institute, Luoyang Heavy Gearbox Co., Ltd., and Jingzhou Giant Whale Transmission Machinery Co., Ltd. The manufactured heavy-load planetary gearbox series products have also been widely used in mines, metallurgy, building materials, coal, and hydropower industries, among which the input power of the roller press suspension series planetary gearboxes of the cement industry developed by the Xi'an Heavy Machinery Research Institute has been Up to 1250KW, planetary gearboxes for aluminum rolling mills, wind power generation speed increaser series products developed by Hangzhou Sifang Heavy Industry Co., Ltd. and Xi'an Heavy Machinery Research Institute have gradually replaced imported products, and are widely used in the domestic wind power industry. . In the manufacture of large ring gears, China's largest ring gear with a diameter of 9.936 meters and a net weight of 80 tons has been manufactured by CITIC Heavy Machinery and is used in the production line of an annual output of 5 million tons of oxide balls from Wuhan Iron and Steel Group. This is used in large-scale sintering machines. Large-scale drives for mills, mills, and rotary kilns, as well as large flexible transmissions for converters and sintering equipment, can be supplied domestically without the need for further imports.
In the development of other types of new products, industry companies have also achieved a lot of achievements, such as the construction of transmission gear and fan and differential energy-saving speed-regulating devices for pumps and gears developed by Xi’an Heavy Machinery Research Institute, Luoyang Zhongzhong Gears Co., Ltd. The large mine elevator planetary gearbox, the mill drive gearbox of Jiangsu Jinxiang Reducer Co., Ltd., and the large three-ring transmission gearbox and transmission of Beijing Taifuli Transmission Co., Ltd. have also been welcomed by the market and have been widely used. .
In terms of capacity expansion and technological transformation of industrial enterprises, they have seen a leap-forward development in recent years. This has benefited from the strong market demand in recent years. On the other hand, they have also been affected by the expansion of production scale and the improvement of manufacturing and manufacturing. In order to further drive the subjective desire of the competitiveness of enterprises, the key processing equipment purchased by major domestic product manufacturers in the past two years, such as large gear grinding machines, boring and milling machines, technical centers, and heat treatment equipment, has accumulated more than 200 units (sets). It is expected that the industry's production capacity will more than double, and the development of technological reforms will certainly have the objective effect of reviewing the scale of the industry, production concentration, and competitiveness. However, there are still many practical problems such as the large number of industrial enterprises, small specifications, and uneven levels. Therefore, with the decline of market demand and the large-scale entry of foreign counterparts into the domestic market, competition in the industry will inevitably intensify, which will certainly promote mergers and acquisitions, integration, and even transitions among industry and enterprises.
In terms of product market competition, foreign companies have become increasingly strong in China in recent years. SEW continues to deploy production and sales bases throughout the country to expand its market share. Companies such as FLEDER, Bangfei, Brevini, FORK, and Sumitomo have also stepped up the pace of establishing production bases and sales centers in China, actively infiltrating into various industries, and advanced management and business concepts of foreign manufacturers, and a rich market. The actual combat and expansion of experience and unique product series will bring challenges and impacts to domestic manufacturers. The domestic manufacturers will feel more and more fierce competition from domestic and foreign competitors.
In terms of the expansion and expansion of domestic transmission products, it is still the main form of multi-medium, low-power medium and small-size products exported or exported with the host. The share of presidents in this area is still relatively small, and efforts are made to improve the quality of products. And expandability, and actively explore the international market, should be an important way for domestic companies to seek market development.
Looking at the current situation of the domestic reducer industry, in order to maintain the healthy and sustainable development of the industry while fully affirming the continuous development and progress of the industry, we should also see the existing problems, and actively study countermeasures and take measures to strive in a relatively short period of time Can make progress. At present, the most outstanding problems in the industry with the external reducer industry are that the industry’s overall new product development capability is weak, process innovation and management are low, and corporate management practices are relatively extensive. A considerable percentage of products are still low-grade and lack international influence. Force product brand, the overall industry scattered, chaotic situation is still more serious. Based on this, to promote mergers and acquisitions among industry-leading companies, and to form a number of group companies with a certain market influence, brands with large scale and strength, and strong product R&D and technical support capabilities. In order to maintain a certain advantage in the competition with its foreign counterparts and to continue to develop.
