  • What are the faults caused by aging reduction motor?

    2022-08-25
    Aging of motor will cause many problems, and the signs are generally the increase of surface temperature, the decrease of self working efficiency and the increase of working current.Aging is divided into several types: aging of motor insulation layer and aging of motor machinery.Aging of the insulation layer of the motor will cause equipment failure of the electrical equipment. Abnormal insulation layer between phases or to the ground of the motor will cause inter turn short circuit or lack of phase operation, or broken rotor bar of the motor will cause insufficient output of the motor and...

  • What lubricating oil is added to the reducer?

    2022-08-25
    During the consultation process of many fans, some users often ask me when to change the lubricating oil of the reducer, how to change the lubricating oil when changing the lubricating oil, and so on. Well, let's take a look at these specific issues today.The reducer is generally lubricated with 40 # or 50 # mechanical oil under normal temperature. In order to improve the performance of the reducer and prolong the service life of the gear reducer, it is recommended to use 70 # or 90 # low pressure gear oil. The lubricating oil can also be reconsidered when working under high and low...

  • It is very important to select and fix the position of the reducer

    2022-08-25
    The components of the reducer, especially the transmission parts on the output shaft, must be installed with care. It is prohibited to use hammer and other tools for explosive installation. The transmission connection parts should be equipped with protective devices when necessary to ensure the transmission effect and service life. Although there are many types of couplings for the reducer, it is not recommended to use rigid fixed couplings, because improper installation of such couplings will cause unnecessary external loads, not only waste energy, but also easily cause bearing fracture and...

  • Uncover the driving principle of six different types of reducers

    2022-08-18
    The reducer is generally used for the transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed running power is meshed with the large gear on the output shaft through the gear with small number of teeth on the input shaft of the reducer to achieve the purpose of reduction. The ratio of the number of teeth of the large and small gears is the transmission ratio.Reducer is a kind of relatively precise machinery. The purpose of using it is to reduce the speed and increase the torque. There are many types and models of reducers, and different ...

  • What are the factors affecting the price difference of four series gear reducers

    2022-08-18
    In fact, the four series gear reducers are only a kind of independent components composed of gear transmission, worm transmission and gear worm transmission enclosed in a rigid shell, which play a very important role in application. At the same time, it is widely used in modern machinery. So what factors can interfere with its quotation? Next, I will give you a specific introduction.The four series gear reducers have many advantages when they are used. For example, it has a reverse self-locking function and can have a large reduction ratio. During application, its input shaft and output shaft ...

  • Analysis on the cause of bearing noise of reducer

    2022-08-18
    The reducer is actually an independent component composed of gear transmission, worm transmission and gear worm transmission enclosed in a rigid shell, which is often used as a reduction transmission device between the original mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. However, in the process of our use, there is a phenomenon that the reducer bearing makes a noise. The following is a brief introduction to the causes of the reducer bearing making a noise....

  • What preparations are required before assembly of reducer

    2022-08-11
    Precautions for reducer assembly preparation:1. The breather valve must be opened before the reducer operates;2. The six assembly forms will cover the failure of the oil splashing mode of the reducer, and the manufacturer shall be consulted;3. In the six assembly forms, the assembly positions of the exhaust valve, oil level inspection bolt and oil drain bolt are different;4. The requirements for the filling amount of lubricating oil in the six assembly forms are different;5. Note that it is usually unrealistic to accurately judge the oil quantity when the reducer is running.Precautions for...

  • Machining and maintenance of gear accessories of precision planetary gear reducer

    2022-08-11
    The processing of gear accessories of the precision planetary gear reducer needs maintenance. First, the precision planetary gear reducer can only be installed on a flat, shock-absorbing and torsion resistant support structure. In any case, it is not allowed to hammer the pulley, coupling, pinion or sprocket into the output shaft, which will damage the bearing and shaft.The precision planetary gear reducer has the advantages of space saving, reliability and durability, high overload bearing capacity, power up to 200kW, low energy consumption, excellent performance, deceleration efficiency up...

  • Which parts of the reducer need to be replaced regularly?

    2022-08-03
    Since many parts of the reducer are vulnerable parts, we should check the reducer regularly. Check whether the internal parts are worn. If any, replace them in time to ensure the normal operation of the reducer. Common vulnerable parts mainly include gears, oil seals and bearings. Let's introduce them one by one.Gear is the core component of reducer. When the reducer works, the gears mesh with the gears to achieve the effect of transmission power. Because the gear is generally made of 20CrMnTi material, the running speed is very high, generally up to 1500 revolutions. Under such high-speed...

  • How to improve the precision level of reducer?

    2022-08-03
    Reducer is a mechanism that uses gear speed converter to decelerate the rotation number of motor (motor) to the required rotation number and obtain large torque. Reducer is widely used in the transmission of power and motion mechanism.Briefly introduce several methods to improve the accuracy level of the reducer:1. Theoretical knowledge is becoming more and more perfect and closer to reality (such as gear strength calculation method, modification technology, deformation calculation, optimization design method, smooth transition of tooth root, new structure, etc.);2.
