Reducer is a power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor (motor) to the required rotation number and obtain a large torque. Among the mechanisms used to transmit power and motion, reducer is widely used.

According to Yubo Zhiye Market Research Center, the industries with large consumption of reducer mainly include: electric machinery, metallurgical machinery, environmental protection machinery, electronics and appliances, road construction machinery, chemical machinery, food machinery, light industrial machinery, mining machinery, transportation machinery, construction machinery, construction 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 reducer used in various industries in China.

With the rapid development of domestic economy and the increase of export volume of heavy machinery industry in recent years, the reducer industry, as an important basic industry, has developed very rapidly. Reducer enterprises are developing towards the expansion of production and marketing scale and the continuous improvement of processing capacity and technical level. The industry prospect of reducer market will be very good in the future.

Foreign countries have been very mature in the design and production of advanced reducer. Some well-known manufacturers have more than 100 years of reducer production experience and a considerable market share. For example, Flender reducer of Siemens is the largest reducer supplier in the industry, and has high attainments in product structure design and manufacturing.

Foreign reducers are widely used in many industries such as electric power, food, construction, mining, water conservancy and so on. Their manufacturing and production standards are also higher than those in China. China's hard tooth reducer standards also come from the production standards of Siemens. The development history of domestic reducer has also been nearly 40 years, with a large number of manufacturers and various forms. At present, there are hundreds of standard series of various domestic general reducers, which can basically meet the needs of various industries for general reducers. However, compared with foreign countries, there is still a large gap in the level of reducer in China. The prominent problems existing in the reducer industry with foreign countries are the weak ability of new product development, low level of process innovation and management.

With the rapid development of domestic economy and the increase of export volume of heavy machinery industry in recent years, the reducer industry, as an important basic industry, has developed very rapidly. Reducer enterprises are developing towards the expansion of production and marketing scale and the continuous improvement of processing capacity and technical level. The industry prospect of reducer market will be very good in the future.

While the market demand for heavy machinery is increasing, the industry has also carried out fruitful work in product upgrading, integration of industrialization and industrialization, energy conservation and emission reduction. In terms of product upgrading, the pace of technological upgrading of old products that have remained unchanged for many years is accelerating. Enterprises in the bridge and gantry crane industry have innovated old products by means of joint or independent research and development, forming an upsurge of product upgrading in the industry. Beijing lifting and Transportation Machinery Research Institute has jointly carried out the lightweight work of bridge crane series with many enterprises, and has made phased progress at present. The industry actively introduces variable frequency speed regulation technology, remote control and information technology to accelerate the upgrading of products to high-end technology. The gearless variable frequency drive main lifting device of crane developed by the industry began to test the water in the market.

The demand for heavy machinery and spare parts in the international market will also grow. With the gradual economic recovery of European and American countries, the re establishment of the status of the real economy in the national economy and the capital construction needs of developing countries, heavy machinery products will have more room for development in the international market.

Heavy machinery is in great demand in the market

The development trend of gear reducer in heavy machinery is promising

With the state's attention to the machinery manufacturing industry, the acceleration of the localization process of major equipment and the commencement of urban transformation, venue construction and other engineering projects, the reducer market has a promising prospect, and the whole industry will still maintain a rapid development trend, especially the growth of gear reducer will be greatly improved, which is related to the fact that most imported equipment adopts gear reducer.

From the analysis and prediction report on the market prospect of the reducer, it is understood that the reducer is a power transmission mechanism. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety, different models and different uses. The designed products of reducer for heavy machinery include all kinds of gear reducer, planetary gear reducer, worm gear reducer and cycloidal pin gear reducer, as well as all kinds of special transmission devices.

Development trend of reducer

① High level and high performance. Cylindrical gears are generally carburized, Quenched and ground, with the bearing capacity increased by more than 4 times, small volume, light weight, low noise, high efficiency and high reliability.

② Building block combination design. The basic parameters adopt priority number, the dimensions and specifications are neat, the parts have strong universality and interchangeability, and the series is easy to expand and renovate, which is conducive to organizing mass production and reducing costs.

③ Diversified types and many variant designs. It gets rid of the traditional single base installation mode, and adds different types such as hollow shaft suspension, floating support base, integrated connection between motor and reducer, multi-directional installation surface and so on, so as to expand the scope of use.

At present, more and more driving equipment in engineering are driven by motor. Due to the high speed and low torque of motor, it is generally impossible to directly drive the execution equipment, so the reducer must be used to transmit power. The commonly used reducer in engineering is the gear reducer. The gear reducer has a long application history. The rapid development of modern industry also puts forward higher requirements for the reducer, mainly in the requirements of higher power capacity, shorter R & D cycle, large torque range, various design forms, high life and high reliability. The significance of this design is to optimize the traditional reducer in combination with the requirements of modern industry and the current production level, and through this design, you can consolidate and comprehensively apply your learned knowledge again, exercise your design and calculation ability, cultivate and improve your reference and selection of standard parameters, the application of calculation formulas and drawings.
