According to preliminary statistics, the industries with a large amount of reducers mainly include: food machinery, electric machinery, metallurgical machinery, environmental protection machinery, electronic appliances, road construction machinery, chemical machinery, light industrial machinery, mining machinery, conveying 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 reducers used in various industries in the country.
Heavy machinery market demand is large
The market demand for heavy machinery equipment and spare parts will also grow.With the gradual recovery of the European and American economies, the re-establishment of the status of the real economy in the economy, and the need for basic construction in the development, heavy machinery products will have more room for development in the market.
While the market demand for heavy machinery has increased, the industry has also carried out fruitful work in product upgrades, integration of industrialization and industrialization, and energy conservation and emission reduction.In terms of product upgrades, the pace of technological updates of old products that have remained unchanged for many years is accelerating.Companies in the gantry crane industry adopt joint or independent research and development methods to innovate old products one after another, forming an upsurge of industry product upgrades.Beijing Research Institute of Crane and Transportation Machinery has jointly carried out series of lightweight work on bridge cranes with many enterprises, and has made phased progress.The industry actively introduces variable frequency speed control transmission technology, remote control and information technology to accelerate the upgrading of products to high-end technology.The crane's gearbox-less variable frequency drive main hoisting device developed by the industry has begun to test the water in the market.
The development trend of gear reducers in heavy machinery is promising
With the emphasis on the machinery manufacturing industry, the acceleration of the localization process of major equipment, and the commencement of urban renovation, venue construction and other engineering projects, the market prospect of the reducer is promising, and the entire industry will maintain a rapid development trend, especially the growth of gear reducers. It will be greatly improved, which is related to the use of gear reducers in most imported equipment.
The reducer is a power transmission mechanism, and its purpose is to reduce the speed and increase the torque.It has a wide variety of different models, and different types have different uses.The products designed for reducers for heavy machinery include various gear reducers, planetary gear reducers, worm gear reducers and cycloid pin wheel reducers, as well as various special transmission devices.
The development trend of reducer
①High level and high performance.Cylindrical gears generally adopt carburizing, quenching and tooth grinding, and the carrying capacity is increased by more than 4 times, with small size, light weight, low noise, high efficiency and high reliability.
②Building block type combination design.The basic parameters adopt the priority number, the size specifications are neat, the parts are universal and interchangeable, the series is easy to expand and the pattern is refurbished, which is conducive to the organization of mass production and the reduction of costs.
③Diversified types and many variant designs.Get rid of the traditional single base installation method, add hollow shaft suspension type, floating support base, integrated connection of motor and reducer, multi-directional installation surface and other different types to expand the scope of use.
