The reducer industry takes the road of energy saving and emission reduction, which is not only reflected in clean production and energy-saving production, but also in reducer products.Although my country's reducer products are relatively mature, compared with high-end products in Europe and the United States, there is still a certain gap in design and performance. At present, the development trend of international motors is simplicity and light weight, while my country's reducer motors are obviously It is much larger than the more common motors in the world.Large motors will not only increase the amount of raw materials used in manufacturing, but also consume more power, which obviously does not meet the standards for energy conservation and emission reduction.At the same time, because the size of the motor is too large, the volume of the reducer will definitely be larger. Because the accessories are large in size and heavy in weight, such a reducer will consume more energy.Therefore, in order to save energy and reduce emissions, it is necessary to optimize the design of the reducer and improve the energy conversion rate of the reducer, so that the reducer can save more power in the application and realize energy saving and emission reduction.With the continuous improvement of domestic equipment technology, Read More

The problem of poor carrying capacity often occurs during the operation of the reducer. According to the analysis of the working principle of the Jinchangcheng reducer, the following three factors affect the carrying capacity of the reducer: 1. The reducer itself affects the manufacturing accuracy and operation of the gear Speed ​​is an internal factor that affects the bearing capacity of the reducer.The ideal motion of the gear pair is that the input and output speeds are constant. Due to the existence of gear processing and assembly errors, the gears will move relative to each other during the motion process, resulting in transmission errors and gear vibrations, which will bring internal additional force to the toothed gears. Load, at this time the reducer will produce a lot of noise, and the carrying capacity will also decrease.2. The influence of the prime mover and the working machine The prime mover and the working machine are external factors that affect the bearing capacity of the reducer. Due to the unevenness of the load, they will bring external additional loads to the reducer.According to the different types of prime movers, the characteristics of the working machine can be divided into Read More

The development of industrial society has promoted the progress of the reducer industry. With the improvement of science and technology, three-ring reducer, planetary reducer, hard tooth surface reducer, gear reducer and other equipment are more and more widely used in various industries.Next, Jin Changcheng will take the planetary reducer as an example to talk about its application in the coal industry.my country is a large coal-producing country in the world. In order to adapt to the rapid increase in coal demand, the installed power of many coal mining machinery has doubled. Therefore, the requirements for the mechanical transmission part are getting higher and higher. The traditional fixed-axis gear train transmission structure can no longer adapt To meet the new work requirements, it is imperative for coal mining machinery to adopt planetary gear transmission.The planetary gear transmission of the planetary reducer has the characteristics of power splitting, and its center wheels can form a coaxial linear transmission, and the internal meshing gear pair is reasonably used, so it can be small in size, light in weight, compact in structure and strong in carrying capacity. features.In addition, the symmetrical structure of the planetary reducer Read More

When the planetary reducer is used in the face of pairing and combination, the operator needs to consider how to choose the gear. In addition to paying attention to the rule that the hardness of the working tooth surface of the small gear is slightly higher than the hardness of the working tooth surface of the large gear, the editor The following specifications are also organized.1. On the premise of satisfying the bending fatigue strength, when the center distance of the planetary reducer is constant, more teeth should be selected, which can improve the coincidence degree, make the transmission stable, and reduce noise.Under the premise of meeting the transmission requirements, the teeth numbers of the large and small gears should be mutually prime, so as to disperse and eliminate the influence of gear manufacturing errors on the transmission, and also avoid the periodic meshing of certain teeth on the large and small gears, so as to make the transmission stable. Reduce noise.2. Adopting a smaller pressure angle can reduce the running noise. Considering the influence of the strength comprehensively, the standard value is usually 20°.When the structure permits, the use of helical gears should be given priority. Read More

In the process of understanding the principle of planetary reducer, you will find that the reduction ratio is very important as an important parameter. If you want to understand the reduction ratio, then start from its calculation. The staff of Jinchangcheng planetary reducer will introduce several kinds of reduction ratio calculation method.1. Define the calculation method: reduction ratio = input speed ÷ output speed.2. General calculation method: reduction ratio = operating torque ÷ 9550 ÷ motor power, motor power input revolutions ÷ operating coefficient, precautions for using MB stepless speed changer.3. Calculation method of the gear train: reduction ratio = number of teeth of the driven gear ÷ number of teeth of the driving gear (if it is a multi-stage gear reduction, then the number of teeth of the driven gear of all meshing pairs of gear sets ÷ the number of teeth of the driving gear, and then the obtained result Just multiply it together, NRV planetary reducer. 4. Calculation method of reduction ratio of belt, chain and friction wheel: reduction ratio = diameter of driven wheel ÷ diameter of driving wheel Read More
