Heavy machinery needs large gear reducer with good prospect
According to preliminary statistics, the industries with large reducer consumption mainly include: food machinery, motors, metallurgical machinery, environmental protection machinery, electronic and electrical equipment, road building 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 is large
The demand for heavy machinery equipment and parts in the international market will also increase. With the gradual recovery of European and American economies, the re establishment of the real economy in the national economy and the demand for capital construction in developing countries, heavy machinery products will have greater development space in the international market.
While the market demand for heavy machinery is increasing, 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 upgrading, the technological upgrading of old products, which has remained unchanged for many years, is accelerating. Enterprises in the bridge crane industry have adopted joint research and development or independent research and development to innovate the old products one by one, forming an upsurge of product upgrading in the industry. Beijing Research Institute of Lifting and Transportation Machinery has carried out a series of lightweight work for bridge cranes with many enterprises, and has made progress at present. The industry actively introduces variable frequency drive technology, remote control and information technology to accelerate the upgrading of products to high-end technology. The main lifting devices of gearless variable frequency drives developed in the industry began to test in the market.
Gear reducer of heavy machinery develops smoothly
With the national attention to the machinery manufacturing industry, the acceleration of the localization process of major equipment, the start of urban reconstruction, site construction and other engineering projects, the reducer market has broad prospects, 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 for most imported equipment.
The reducer is a power transmission mechanism. The purpose is to reduce speed and increase torque. It has many kinds, different models, different kinds and different purposes. The reducer design products of heavy machinery include various gear reducers, planetary gear reducers, worm gear reducers, cycloidal pin gear reducers, and various special transmission devices.
Development trend of reducer
① High level, high performance. After carburizing, quenching and grinding, the capacity of cylindrical gears has been increased by more than 4 times, with small volume, light weight, low noise, high efficiency and high reliability.
② Modular design. The basic parameters are priority number, neat size and specification, universal and interchangeable parts, easy expansion and renovation of series, which is conducive to mass production and cost reduction.
③ Various types and designs. It gets rid of the traditional single base installation mode, and adds different types, such as hollow shaft suspension type, floating support base, integrated connection of motor and reducer, multi-directional mounting surface, to expand the scope of use.
