Domestic Gear Reducer Development Looks Good

According to preliminary statistics, the industries with large reduction gears mainly include: electrical machinery, metallurgical machinery, environmental protection machinery, electronic appliances, road construction machinery, chemical machinery, food machinery, light industrial machinery, mining machinery, transportation machinery, construction machinery, and building materials. Machinery, cement machinery, rubber machinery, water conservancy machinery, petroleum machinery, etc. The use of speed reducer products in these industries has accounted for 60% to 70% of the total number of decelerators used in various industries in the country.

Reducer at home and abroad

Foreign countries have been very mature in the design and production of advanced speed reducers. Some well-known manufacturers already have more than one hundred years of experience in the production of speed reducers, and their market share is also very impressive. For example, Siemens' FLENDER reducer is the largest supplier of reducers in the industry and has a high level of success in product design and manufacturing.

Foreign reducers are widely used in electric power, food, construction, mining, water conservancy and many other industries. Their manufacturing and production standards are also higher than those in China. China's hard tooth reducer standards also come from Siemens' production standards. The development history of domestic reducers is also nearly 40 years. There are a large number of manufacturers and the forms are various. At present, the standard series of all kinds of universal reducers in China has reached hundreds, which can basically meet the demand for universal reducers in various industries. However, compared with foreign countries, there is still a large gap between China's speed reducer and the relatively outstanding problems existing in the foreign and domestic reducer industry are that the industry's overall new product development capability is weak, and process innovation and management are low.

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 the processing capacity and technology level are continuously improving. The industry outlook for the future reducer market will be excellent.

Heavy machinery market demand

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. The enterprises of the bridge gantry crane industry used joint or independent research and development methods to innovate the old products one after another, forming an upsurge of product upgrading in the industry. The Beijing Lifting Transport Machinery Research Institute and many other companies have carried out lightweight work on the bridge crane series 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 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 infrastructure needs of developing countries, heavy machinery products will have greater room for development in the international 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 gear 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 4 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 engineering are using motor drives. Because the motor has a lower speed and a lower torque, it is generally impossible to drive the actuator directly. 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 research and development cycle, large torque range, various design forms, high life 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, the knowledge that they have already learned can be consolidated and comprehensively used, and their own design and calculation capabilities can be exercised. Improve your own review and selection of standard parameters, use of calculation formulas, and drawings.
