Reducer is a kind of power transmission mechanism, which reduces the rotation of motor (motor) to the desired number of revolutions by using the speed converter of gears and obtains larger torque. In the current mechanism for transmitting power and motion, the application of reducer is quite extensive. It can be found in almost all kinds of mechanical transmission systems, from ships, automobiles, locomotives, heavy construction machinery, machinery and automated production equipment used in machinery industry, to household appliances, clocks and so on. Load, accurate angle transmission can see the application of the reducer, and in industrial applications, the reducer has deceleration and increase torque function.
In the 1970s and 1980s, the world's reducer technology has made great progress, and closely combined with the development of new technology revolution.
Since the reform and opening up, China has introduced a number of advanced processing equipment, through the introduction, digestion, absorption of foreign advanced technology and scientific research, and gradually mastered a variety of high-speed and low-speed heavy-duty gear design and manufacturing technology. However, the technical level of most reducers in China is still not high, the old products can not be replaced immediately, and the coexistence of new and old products will go through a long period of time.
Due to the impact of the global economic crisis, a number of enterprises originally engaged in exporting reducers have turned to the domestic market to seize the market share of domestic reducers. This competition has brought greater competition and pressure to the reducer manufacturers which were originally positioned in the domestic market. With the impact of tax policy and external economic pressure, some reducer enterprises began to purchase high-end gear grinders and other equipment, and this behavior also set off the domestic reducer industry standards.
Compared with the imported reducer equipment, the prologue n from the past 7-Stage gear accuracy to 6-degree gear accuracy is already comparable, but in terms of time limit is much shorter than the close-mouth reducer, and more competitive.
The domestic reducer will be fully upgraded in 2010.
