- Do you know the classification and application of helical gear reducer?Helical gear reducer is an extension of gear reducer. Due to the adoption of helical gear, its allowable minimum number of teeth is less than that of spur gear, which greatly reduces the probability of undercutting failure of reducer. The transmission accuracy of helical gears has more advantages th

- What is the development prospect of the reducer industry?After experiencing long-term tempering and development in the market, it has gradually evolved into a leading force covering the Chinese market, and the reducer has shown the vitality of shocking the world.With the rapid development of the domestic economy in recent years, the export volume of the heavy machinery industry has increased, and the reducer industry, which is an important basic industry, has developed extremely rapidly.Reducer enterprises are expanding their production and sales scale, and their processing capacity and technical level are continuously improving.In the future, the industry prospect of the reducer market will be bright.Benefiting from the continuous deepening of industrialization and urbanization and the country's emphasis on machinery manufacturing, the reducer industry is one of my country's basic equipment industries.At the same time, my country's economic development has entered a period of deep adjustment, and the reducer industry has also entered into transformation and upgrading.Analysis of the development prospects of the reducer industry in 2017: Downstream industries promote the development of reducers as a must in modernization
- Correct use of gear reducerTips for using the gear reduction motor: 1. After the gear reduction motor has been running for 200~300 hours, the oil should be changed for the first time. In the future use, the quality of the oil should be checked regularly, and the oil mixed with impurities or deteriorated must be replaced in time.Under normal circumstances, for the gear reduction motor that has been continuously working for a long time, the new oil should be replaced according to 5000 hours of operation or once a year. Mixed use, oils with the same grade but different viscosities are allowed to be mixed.2.When changing oil, wait for the geared motor to cool down until there is no danger of burning, but it should still be kept warm, because after complete cooling, the viscosity of the oil will increase and it will be difficult to drain the oil.Note: Cut off the power supply of the transmission device to prevent unintentional power-on!3.During work, if you find that the oil temperature rises above 80°C or the oil pool temperature exceeds 100°C or produces abnormal noise, you should stop using it.
- Five reasons for you to choose the reducerWith the further development of China's machinery industry, more and more users are using geared motors, although the universal application of geared motors in many mechanical equipment has been widely recognized.However, there are still many users who have never been in contact with geared motors who know little about geared motors and think that a simple transmission structure can achieve the function of geared motors, but this is not entirely the case.1. Adding a deceleration motor can reduce the moment of inertia, generally the square of the speed ratio reduces, and can control the start, stop and speed change in time.2. The torque increased by the deceleration motor is equivalent to increasing the input power, which can reduce the power required by the input motor (in the case of speed regulation). Generally, the motor is expensive, so the deceleration motor is considered.3. The deceleration motor has the function of protecting the motor during transmission. The decelerator bears a large torque during operation. When it is overloaded, only the value of the overload divided by the reduction ratio is transmitted to the motor. If it is directly borne by the motor, it may cause damage to the motor.
- What should I do if the reducer has abnormal vibration and noise?The reducer is an independent component consisting of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving part and the working machine.During the long-term operation of the reducer, there will be abnormal vibration and noise. Let's take a look at the specific reasons below.The reason for the abnormal sound may be that the bearing seat is worn, the gap becomes larger, and the abnormal sound occurs.The gears are worn, the meshing gap becomes larger, and abnormal noise is generated.Lack of lubricating oil, dry grinding sound.The shaft of the reducer is bent and deformed, causing abnormal noise; the load is too large, causing abnormal noise.An important factor for shaft wear is the properties of the metal used to manufacture the shaft. Although the metal has good hardness, it has poor impact resistance and cannot be restored after deformation.And the fatigue resistance is poor, so it is easy to cause fatigue wear such as bearing chamber wear, shaft head wear, journal wear, and shaft sleeve wear of the equipment. Most of the shaft wear is not easy to be found. When people notice it, it is often already cause the machine to beat
