1. The circumferential speed of gear transmission shall not be greater than 20 m / s. From the perspective of the growth environment of enterprises in the industry, in recent years, private enterprises in Jiangsu Province and Zhejiang Province have grown rapidly, and have become a new force in the industry.

2. The working environment temperature is - 40-45 ℃. If it is lower than 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting. The gear reducer can be used in both positive and negative directions. They keep up with the market changes, mediate the product layout in real time, and the requirements for product quality are also constantly improving.

During the Tenth Five Year Plan period, due to the country's acceptance of positive financial policies, stimulating domestic demand, strengthening asset investment, the growth of various industries has entered a slow lane. In addition, there are many reducer manufacturers in Zibo, Shandong Province. Experts speculate that during the "Eleventh Five Year Plan" period, due to the growth of national group economy, the growth rate of the total economy of the hardened gear reducer industry will still reach double digits. Gear reducer is an external involute helical gear reducer produced according to the national professional standard zbj19004-88. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields. Products have grown from the last single cycloid reducer to five categories of products today, namely cycloid reducer, continuously variable transmission, gear reducer, hard tooth surface reducer, worm gear reducer and electric roller.

From the reducer branch of China General Machinery Industry Association, with the further strengthening of the national foundation, China's reducer industry has lost rapid growth. The application scope of gear reducer is as follows: high speed shaft rotation is not more than 1500 rpm. According to the statistics of the gearbox branch, last year, the whole industry consumed 450000 reducers, sold 2 billion yuan and exported about 100 million US dollars. Some private enterprises with fast growth rate keep growing after completing the original accumulation. In order to enhance their competitiveness, they have increased the capital investment in purchasing testing equipment, implementing equipment and expanding factories. Their processing ability and skill level have made rapid progress. At the same time, they also attach great importance to the cultivation and introduction of talents. Enterprises have begun to grow towards paradigm and standardization.

According to statistics at the beginning, the most important industries that use reducer are: electric machinery, metallurgical machinery, environmental protection machinery, electronic appliances, road building machinery, chemical machinery, food machinery, light industry machinery, mining machinery, transportation machinery, construction machinery, building materials machinery, cement machinery, rubber machinery, water conservancy machinery, petroleum machinery, etc, The number of reducer products used by these industries has accounted for 60% - 70% of the total number of reducers used by various industries in the world. Therefore, experts in the industry hope that enterprises will pay close attention to the development and manufacture of gear reducers, especially large-scale hardened gear reducers and medium and small power reducers, so as to meet the market demand. It is estimated that during the "Eleventh Five Year Plan" period, with the country's emphasis on the machine manufacturing industry, the acceleration of the localization process of large equipment, and the commencement of projects such as the urban reform and the establishment of stadiums and gymnasiums, the market prospect of reducer is promising, and the whole industry will continue to maintain the rapid growth trend, especially the growth of gear reducer will be greatly improved, This is related to the fact that most of the imported equipments are equipped with gear reducers. Mechanical gear reducer scope of application machinery professional production of various: gear reducer, cycloid reducer, worm gear reducer, envelope reducer, hard tooth surface reducer, worm screw elevator, ball screw elevator, etc.
