Tianjin planetary gear reducer manufacturers interpret the current status of China's gear transmission industry
Introduction: With the tide of national economic development and development, under the guidance of relevant state ministries and agencies, China's gear transmission manufacturing industry has developed by leaps and bounds. Gears and their gear products are important basic parts of mechanical equipment, and the main transmission parts of most machinery complete sets are gear transmissions.
“十五”期间得到了快速发展： 2005 年齿轮行业的年产值由 2000 年的 240 亿元增加到 683 亿元，年复合增长率 23.27% ，已成为中国机械基础件中规模最大的行业。 China's gear industry has developed rapidly during the "Tenth Five-Year Plan" period: In 2005 , the annual output value of the gear industry increased from 24 billion yuan in 2000 to 68.3 billion yuan, with a compound annual growth rate of 23.27% , which has become the largest scale in China's mechanical infrastructure Industry. In terms of market demand and production scale, China's gear industry has surpassed Italy in the global rankings, ranking fourth in the world. China's gear industry applications are:
First of all, in terms of vehicle drive axles, active and passive spiral bevel gears, spur bevel gears and wheel reducers, most of them can meet domestic supporting needs. The drive axle and bevel gear industry represented by Dongfeng Axle Bridge are integrating and reorganizing and developing, and we have seen the hope of rapid development.
Characteristics of gear transmission
1 ）传递的功率大， 2 ）速度范围广， 3 ）效率高， 4 ）工作可靠，寿命长， 5 ）结构紧凑， 6 ）能保证恒定传动比。 1. Advantages: 1 ) Large transfer power, 2 ) Wide speed range, 3 ) High efficiency, 4 ) Reliable operation and long life, 5 ) Compact structure, 6 ) Can guarantee constant transmission ratio.
( 含重、中、轻、微 ) ，轿车变速箱，摩托车齿轮、工程机械换挡变速箱，大、中型农机变速传动的配套，已经基本立足国内生产，基本满足了主机厂的配套需要，并已经有部分齿轮件出口或变速箱出口。 Secondly, the matching of manual gearboxes for automobiles ( including heavy, medium, light, and micro ) , car gearboxes, motorcycle gears, shifting gearboxes for engineering machinery, and large and medium-sized agricultural machinery transmissions have basically been based on domestic production and have basically met the requirements. The supporting equipment of the OEM needs, and some gear parts or gearboxes have been exported. In terms of auto transmissions, they are still controlled by imported products.
1 ）制造及安装精度要求高，成本高， 2 ）不适于两轴中心距过大的传动， 3 ）不宜用于振动冲击较大的场合。 2. Disadvantages: 1 ) High requirements for manufacturing and installation accuracy, high cost, 2 ) Not suitable for transmission with excessive center distance between two shafts, 3 ) Not suitable for occasions with large vibration impact.
( 南京高速齿轮箱厂 ) 、重庆齿轮箱厂、杭州前进齿轮箱集团、郑州机械研究所、洛阳中重减速机公司、沈阳矿山减速机公司为代表的企业。 Third, in the manufacturing of high-speed and heavy-duty gear transmissions, China has Nanjing High-precision Gear Co., Ltd. ( Nanjing High-speed Gearbox Factory ) , Chongqing Gearbox Factory, Hangzhou Qianjin Gearbox Group, Zhengzhou Machinery Research Institute, Luoyang Zhonghe Deceleration Machinery companies, Shenyang Mining Reducer Company as the representative enterprises. In the process of introducing these technologies, these enterprises have made significant contributions to the development of China's large-scale complete sets of equipment and the development of the shipbuilding industry.
SEW 等一批国外独资企业的进入激活了中国工业通用变速箱企业为代表，在产品系列化、模块化、质量与技术水平方面，最近五年有了突飞猛进的发展，形成了与国际品牌的激烈竞争。 Fourth, in the field of industrial general transmissions, the entry of a number of foreign-owned enterprises such as SEW has activated the representative of China's industrial general transmissions. In terms of product serialization, modularity, quality and technical level, the company has made rapid progress in the past five years. Development has formed fierce competition with international brands. Some products produced by Chinese enterprises have reached the international level, and some products have been exported to Europe and the United States.
Fifth, in terms of special and dedicated wheel transmission, such as non-circular gears, plastic gears, powder metallurgy gears, small modulus gears, etc., China has not formed a leading enterprise at present, and its technological potential has yet to be realized.
Sixth, in the area of gear special equipment, private enterprises have developed rapidly in the past five years, while state-owned enterprises have developed relatively slowly. Most state-owned gear equipment manufacturing enterprises have made slower progress in equipment reliability indicators, resulting in most of the leading finishing equipment in the gear industry still being imported. The hopes for localization of equipment for some gear enterprises mainly include: worm wheel grinding machine of Qinchuan Machine Tool Factory; CNC machine tools of Chongqing Machine Tool Factory and Nanjing Second Captain; successful development of spiral bevel gear grinding machine tools; CNC spiral screw machine of Tianjin Yuanhao Company Mass supply of bevel gear cutting machine tools; Hangzhou Tianchen Precision Gear Checker, Measuring Tool, Fixture; Great Wall Lubricant serves the lubrication market of the gear industry. All these make our gear industry see the hope of independent innovation and independent development.
