Heavy machinery demand large gear reducer prospects
According to preliminary statistics, the amount of reducer is relatively large industry: food machinery, electrical machinery, metallurgical machinery, environmental protection machinery, electrical appliances, road construction machinery, chemical machinery, light industry machinery, mining machinery, transportation machinery, construction machinery, building materials Machinery, cement machinery, rubber machinery, water machinery, oil machinery, these industries use the number of reducer products accounted for the industry to use the total number of reducer 60% -70%.
Heavy machinery market demand
The demand for heavy machinery and spare parts in the international market will also increase. With the gradual recovery of Europe and the United States economy, to re-establish the status of the real economy in the national economy, as well as the basic construction needs of developing countries, heavy machinery products in the international market will have more room for development.
In the heavy machinery market demand increases at the same time, the industry is also product upgrades, two fusion, energy-saving emission reduction carried out fruitful work. In the product upgrades, many years of the old product technology update pace is accelerating. Bridge gantry crane industry enterprises using joint or independent research and development methods, have the old product innovation, the formation of the industry to upgrade the product boom. Beijing Lifting and Transportation Machinery Research Institute, together with a number of enterprises to carry out the bridge crane series of lightweight work, has made progress in the stage. Industry actively introduce variable frequency drive technology, remote control and information technology to speed up the product to the high-end technology upgrades. Industry-developed cranes without gearboxes The main booster of the variable frequency drive starts to test the water in the market.
The development trend of gear reducer in heavy machinery is promising
With the country's attention to the machinery manufacturing industry, the acceleration of the localization of major equipment and urban transformation, construction and other projects started, reducer market prospects, the industry will maintain a rapid development trend, especially gear reducer Growth will be greatly improved, which is mostly supporting the use of imported gear reducer gear related.
The reducer is a power transmission mechanism that uses it to reduce the speed and increase the torque. It has a wide variety of models, different types, different types have different uses. Heavy-duty mechanical reducer design products include various types of gear reducer, planetary gear reducer, worm gear reducer and cycloid reducer, also includes a variety of special drive.
Development trend of reducer
① high level, high performance. Cylindrical gears generally use carburizing quenching, grinding teeth, carrying capacity to improve more than 4 times, small size, light weight, low noise, high efficiency, high reliability.
Building block design. The basic parameters of the use of priority, size neat specifications, parts versatility and interchangeability, easy to expand the series and pattern renovation, which will help organize mass production and reduce costs.
③ type diversification, variable design and more. Out of the traditional single base installation, adding a hollow shaft suspension, floating support base, motor and reducer integration, multi-directional installation surface and other different types, to expand the use of range.
