Heavy machinery market demand is large
The international market's demand for heavy machinery equipment and spare parts will also increase.With the gradual recovery of the economies of European and American countries, 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 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 bridge gantry crane industry have adopted 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 Conveyor Machinery has carried out a series of lightweight work on bridge cranes in conjunction with many companies, 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 industry-developed crane's gearbox-less frequency conversion drive main hoisting device has begun to test the water in the market.
The development trend of gear reducers in heavy machinery is promising
As the country attaches great importance to the machinery manufacturing industry, the acceleration of the localization of major equipment and the start of construction projects such as urban transformation and venue construction, the market for reducers is promising, and the entire industry will continue to maintain a rapid development trend, especially for gear reducers. The growth 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 dimensions are neat, the parts are universal and interchangeable, the series is easy to expand and the pattern is renovated, 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 mounting surface and other different types to expand the scope of use.
