With the rapid development of the domestic economy in recent years, the export volume of the heavy machinery industry has increased, and the development of the retarder industry as an important basic industry has been extremely rapid. The reducer companies are expanding their production and sales scales, and their processing capacity and technology levels are continuously improving. The industry outlook for the future reducer market will be excellent.

Heavy machinery market demand

The demand for heavy machinery equipment and spare parts in the international market will also grow. With the gradual recovery of the economies of Europe and the United States, the re-establishment of the status of the real economy in the national economy, as well as the basic construction needs of developing countries, heavy machinery products will have greater room for development in the international market.

While the demand for heavy machinery has increased, the industry has also carried out fruitful work in terms of product upgrading, integration, 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. Bridge-gate crane industry companies adopt joint or independent research and development methods to innovate old products one after another, forming an upsurge of industry product upgrading. The Beijing Lifting Transport Machinery Research Institute and many other companies have carried out lightweight work on bridge cranes and have made progress in stages. The industry has actively introduced variable frequency drive technology, remote control and information technology to accelerate the upgrading of products to high-end technologies. The industry-developed crane-free gearbox variable frequency drive main hoist has begun to test water in the market.

The development trend of gear reducer in heavy machinery is promising

With the country’s emphasis on the machinery manufacturing industry, the acceleration of the process of localization of major equipment, and the start of construction projects such as urban renovation and venue construction, the market prospect of the reducer is promising, and the entire industry will maintain a rapid development trend, especially the gear reducer. The growth will be greatly increased, which is related to the use of gear reducers for most of the 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 types of gear reducers, planetary gear reducers, worm gear reducers and cycloidal pin reducers, as well as various special transmissions.

The development trend of reducer

1 High level and high performance. Cylindrical gears are generally carburized, quenched and ground to increase their load carrying capacity by more than four times. They are small in size, light in weight, low in noise, highly efficient, and highly reliable.

2 building block design. The basic parameters adopt the priority number, the size and specification are neat, the parts are versatile and interchangeable, the series is easy to expand and the patterns are refurbished, which is conducive to mass production and cost reduction.

3 types of diversification, more variant design. The traditional single base installation method is eliminated, and the hollow shaft suspension type, the floating support base, the integral connection of the motor and the speed reducer, and the multi-directional mounting surface are added to expand the scope of use.

At present, more and more drive devices in the project are using motor drives. Because the motor has a lower speed and a lower torque, the drive device cannot be directly driven. This requires the use of a speed reducer to transmit power. The gear reducer commonly used in engineering is a gear speed reducer. The gear reducer has a long history of application. The rapid development of modern industry also puts forward higher requirements for the reducer, which is mainly manifested in the requirement of higher power capacity and more. Short R&D cycle, large torque range, diversified design forms, high longevity and high reliability. The significance of this design lies in the optimization of traditional speed reducers combined with the requirements of modern industry and the current level of production. Through this design, we can once again consolidate and comprehensively use the knowledge we have learned, and exercise our own design and calculation capabilities. Improve your own review and selection of standard parameters, use of calculation formulas, and drawings.
