According to preliminary statistics, industries with large consumption of reducers mainly include: food machinery, electrical machinery, metallurgical machinery, environmental protection machinery, electronic and electrical equipment, road construction machinery, chemical machinery, light industrial machinery, mining machinery, and transportation machinery., construction machinery, building materials machinery, cement machinery, rubber machinery, water conservancy machinery, petroleum machinery, etc.The number of reducer products used in these industries has accounted for 60%-70% of the total number of various reducers in China's industry.
Heavy machinery market demand
The demand for heavy machinery equipment and parts in the international market will also increase.With the gradual recovery of the European and American economies, the re-establishment of the status of the real economy in the national economy and the basic construction needs of developing countries, heavy machinery products will have more room for development in the international market.
While the market demand for heavy machinery continues to increase, the industry has also carried out fruitful work in product upgrading, integration of industrialization and industrialization, and energy conservation and emission reduction.In terms of product upgrades, the pace of technology upgrades for old products that have remained unchanged for many years is accelerating.Enterprises in the bridge crane industry adopt joint research and development or independent research and development to innovate old products one by one, forming an upsurge of product upgrading in the industry.The Beijing Institute of Lifting and Transportation Machinery has carried out a series of lightweight work on bridge cranes with a number of companies, and progress has been made so far.The industry is actively introducing variable frequency drive technology, remote control and information technology to speed up the upgrading of products to high-end technology.Industry-developed gearless variable frequency drives for major lifting gear began to test the waters in the market.
Heavy machinery gear reducer develops smoothly
With the country's attention to the machinery manufacturing industry, the acceleration of the localization of major equipment, the start of urban renovation, site construction and other engineering projects, the market prospect of the reducer is broad, and the entire industry will maintain rapid development.The trend, especially the growth of gear reducers will be greatly improved, which is related to the use of gear reducers in most imported equipment.
The reducer is a power transmission mechanism.Its purpose is to reduce speed and increase torque.It has many kinds, different models, different kinds and different uses.Reducer design products for heavy machinery include various gear reducers, planetary gear reducers, worm gear reducers and cycloidal pin gear reducers, as well as various special transmissions.
The development trend of reducer
① High level, high performance.Cylindrical gears are generally carburized, quenched and ground, the capacity is increased by more than 4 times, the volume is small, the weight is light, the noise is small, the efficiency is high, and the reliability is high.
②Modular design.The basic parameters are priority numbers, neat sizes and specifications, common and interchangeable parts, easy expansion and refurbishment of the series, which is conducive to mass production and cost reduction.
③ Various types and designs.It gets rid of the traditional single base installation method, and adds different types such as hollow shaft suspension, floating support base, integrated connection of motor and reducer, multi-directional mounting surface, etc., to expand the scope of use.
