Gear reducer 1. The worm gear reducer is combined with international technical requirements for manufacturing with high technology content. 2. Space-saving, reliable and durable, with stand high overloads capacity, power up to 90KW. 3. Low power consumption, superior performance, reducer efficiency up to 95%. 4. Little vibration, low noise, energy saving, made of high quality section steel, steel cast iron box, gear surface has high-frequency heat treatment. 5. Through precision machined processing, ensure the accuracy of the parallel shaft and positioning. All this constitutes a gear reducer assembly configuration of various types of motor, mechatronics, fully guaranteed product quality characteristics.



Cycloidal reducer Planetary cycloid reducer uses planetary transmission principle. It uses a deceleration mechanism cycloid engaged state-of-the-art design with novel structure. This reducer has replaced ordinary cylindrical gear reducer and cylindrical worm reducer. It is widely used in the fields of military, aerospace, metallurgy, mining, petroleum, chemical, shipbuilding, light industry, food, textile, printing and dyeing, pharmaceutical, rubber, plastic, and lifting and transport. Characteristics (provided by speed reducer supplier) 1. High transmission ratio. In grade one deceleration gear ratio is 1/6--1/87. The double reduction the transmission ratio is 1/99--1/7569; transmission ratio of the third reduction is 1/5841--1/658503. Besides, there are also other specified sizes according to the needs of the multi-level combination. 2. High transmission efficiency. Since the engaging portion with a rolling engagement, generally speaking the transmission efficiency is 90% - 95%. 3. Compact structure, small size, and light weight. Compared to the ordinary cylindrical gear, the cycloidal reducer can reduce 2/1--2/3. 4. Less failure, but long life. The main transmission mesh pieces are made from bearing steel by grinding manufacturing. Therefore, it has excellent mechanical properties and wearing resistance. Besides, because of its rolling friction, it has less failure but long life. 5. Smooth and reliable operation. Transmission process is more multi-tooth meshing, so the operation is smooth and reliable with low noise. 6. Easy disassembly and easy maintenance. 7. Strong overload capacity, impact resistance, and a small moment of inertia. All those are applied to starting of frequent and reversing operation.

Basic Knowledge of Gear Reducer

The gear reducer is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceutical and other fields. The gear reducer should be used when: 1. High-speed shaft under 1500 rev / min 2. Gear peripheral speed is less than 20 m / sec 3. The working environment temperature is around -40-45 ℃. If less than 0 °C, before start the oil should be preheated to a temperature above 0 ℃ 4. The gear reducer can be used in both directions



Machine Features 1. Gear is made of high-strength low-carbon alloy steel carburized. The surface hardness reaches HRC58-62 and the gears are processed by CNC grinding with high accuracy and good contact. 2. Transmission rate: single level is greater than 96.5%, two-stage is more than 93%, and three –level is more than 90%. 3. Smooth operation, low noise. 4. Small size, light weight, long life, and high load carrying capacity. 5. Easy to be overhauled, and easy to install

Power speed ratio torque reduction ratio: 25 ~ 4000r/min (RX, R, K series combination can achieve greater speed ratio) Output torque: 2600000Nm Motor power: 0.4-12934kW

Maintenance of gear reducer First, the reducer (such as helical gear reducer) uses 460 # load industrial gear oil, and working environment temperature is 0 to 40 ° C. Second, after the first 100 hours of use, you should wash inner cavity replaced with new gear oil after oil change once every 2,000 hours. Third, disassembly reducer should avoid hammering in order to avoid damage to the normal mechanical. Fourth, if shaft connected at oil leakage phenomenon, skeleton oil seal and seals should be replaced.

Features of four series of gear reducer 1. R, K, S, F four series gear reducers including worm gear reducer are designed and manufactured based on module combination system. They have lots of motor combinations, install forms and structure programs. They have fine drive score level which can meet different use conditions to achieve mechatronics. 2. The four series gear reducers use unit structure modular design principle which provide a significant reduction in the types and inventory parts. 3. The four series of gear reducers drive efficiency with low energy consumption and superior performance. 4. They have the high rigidity ribbed cast iron box. The gears are made of high quality alloy steel with hardened surface carburizing by precision machining grinding. They provide smooth transmission with low noise, high carrying capacity, low temperature rise, and long life.

Development Trends of China Reducer industry in 2013

The history of the development of reducer industry

Throughout the course of development of China's reducer, since the 1980s, due to the all-round development of the technology of the world, the production technology of gear reducer in China is relatively mature. During this period, our the reducer industry has gone through a long process of development, from the blind imitation of types of foreign worm gear reducer technology applications to the independent design, and now the wide use of a variety of new technologies make our own design and manufacturing capabilities can meet the basic domestic needs, to speed up the pace of development of the industry reducer.



The large scale of China reducer industry

Due to the impact of the economic crisis, many reducer equipments which are ready for export quickly move the goal to the domestic market, which has brought tremendous competitive pressure to the reducer market, and the China reducer industry enterprises put forward higher requirements on the quality of their products. In addition, with the energy saving and environmental protection has become the common topic in the world, and the reducer enterprise is launched to the R & D and production of environmentally friendly reducer.

As we all know, the machinery and equipment industry in China in the past were based on extensive production mode, while in recent years, with the scarcity of various types of energy, enterprises gradually found that this mode of production is not suitable for the sustainable development policy and also does not have much development prospects. So we seek other ways of production, and the reducer industry has committed to building energy saving mode of production, and gradually became a relatively mature enterprise system. Large worm gear speed reducer consume more materials, and the work power consumption will also increase, therefore reducer producers begin moving equipment to the international trends to develop simple, lightweight, environmentally friendly reducer in the market, in order to open up the market competitiveness and increase the corporate brand.

In summary, the development of our reducer industry is rapid, However, because most of the enterprises are the introduction of foreign advanced technology research and development of products, the production mode is similar, and therefore a unique device must be equipped in the fierce market competition and was sufficient to occupy the industry market, and environmentally friendly reducer is undoubtedly one of the goals of the development of the industry now, supposed to calm in the face of various enterprises and in the face of fierce market competition, and take appropriate measures in accordance with their respective enterprise production system, speeding up the pace of product innovation is bound to break through the bottleneck.
