The Development Trends of the General Reducer

First, high-level, high-performance

Cylindrical gear commonly use carburizing and grinding teeth and the carrying capacity is increased more than four times, gear reducer has the small size, light weight, low noise, high efficiency and high reliability.

Second, modular combination design

The basic parameters uses the priority number, the size and specifications are tidy and the parts commonality and interchangeability are strong, the series are easy to be expanded, which is conducive to the organization of mass production and reduce costs.

Third, diverse type and variant design of the reducer

It gets rid of the traditional single base installation, adding the hollow shaft suspension, floating support base, motor and reducer integrated connection, the different types of multi-directional mounting surface, expanding the use of range.

The main factors prompting the level of reducer:

First, theoretical knowledge of gear speed reducers is maturing and closer to the actual situation(such as gear strength calculation method, modification technology, the deformation calculation, optimization design method, the tooth root smooth transition, the new structure, etc.).

Second, take use of the good material, and commonly use a variety of high-quality alloy steel forgings, the level of control the quality of materials and heat treatment has been improved.

Third, structural design is more reasonable.

Fourth, machining accuracy is improved to ISO5-6 level. Fifth, bearing quality and life expectancy has increased.

Sixth, lubricant quality is improved. Since the 1960s, China has developed a standard JB1130-70 "cylindrical gear reducer" and a number of generic reducer standards. Besides the OEMs homemade supporting, a number of reducer professional production plants are formed. Currently, there are about hundreds of enterprises producing reducers and an annual output of universal reducer is about 250,000 units, and has contributed to the development of China's machinery products. Most of the reducers in the 1960s were manufactured with reference to the Soviet Union in the 1940s and 1950s technology, in spite it obtained some development, they were limited to the design, the level of technology and equipment conditions, there is a wide gap between their overall level of international standards. Since the reform and opening up, China has introduced a number of advanced processing equipment, through the introduction, digestion and absorption of foreign advanced technology and scientific research, and gradually mastered the design and manufacture of a variety of high-speed and low-speed heavy duty gear device technology.
