However, compared with foreign countries, there is still a big gap in the level of reducer in China. Compared with foreign countries, the outstanding problems of reducer industry are the weak ability of new product development, low level of process innovation and management.

With the rapid development of domestic economy in recent years, the export volume of heavy machinery industry is increasing. As an important basic industry, the reducer industry is developing rapidly. Reducer enterprises are expanding the scale of production and marketing, processing capacity and technical level continue to improve development. In the future, the reducer market will have a bright future.

Heavy machinery market demand

The demand for heavy machinery and spare parts in the international market will increase. With the gradual recovery of European and American economies, 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 development space in the international market. With the increase of heavy machinery market demand, 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 technology upgrading of old products that have remained unchanged for many years is accelerating. Bridge and gantry crane industry enterprises adopt the way of joint or independent research and development, and innovate the old products one after another, forming the upsurge of industry product upgrading. Beijing Research Institute of hoisting and transportation machinery has cooperated with many enterprises to carry out the lightweight work of bridge crane series, and has made phased progress at present. The industry actively introduces variable frequency drive technology, remote control and information technology to speed up the upgrading of products to high-end technology. The main lifting device of crane without gearbox frequency conversion drive developed by the industry began to test in the market.

① High level, high performance

Carburizing, quenching and gear grinding are widely used in cylindrical gears. The bearing capacity is increased by more than 4 times. The cylindrical gears are small in size, light in weight, low in noise, high in efficiency and high in reliability.

② Modular design

It is easy to expand and renovate the series, which is conducive to mass production and cost reduction.

③ Various types and variant designs

It gets rid of the traditional single base installation mode, and adds different types, such as hollow shaft suspension type, floating support base, integrated connection of motor and reducer, and multi-directional installation surface, so as to expand the scope of application.

At present, more and more driving equipment in engineering has been driven by motor. Due to the high speed and low torque of motor, it is generally unable to directly drive the executive equipment, so it is necessary to use reducer to transfer power. Gear reducer is commonly used in engineering. Gear reducer has a long history of application. The rapid development of modern industry also puts forward higher requirements for reducer, mainly in higher power capacity, shorter R & D cycle, large torque range, various design forms, high life and high reliability.
