- 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
- What gear oil is used for SEW reducer?SEW reducer uses No. 220-680 gear oil. The gear oil is mainly used to lubricate gears and bearings, prevent wear and rust, and help gears to dissipate heat.Automotive gear oil is used in gear transmission mechanisms such as automotive steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oils can be used for lubrication, anti-wear, cooling, heat dissipation, anti-corrosion, anti-rust, cleaning and lowering of gears. Surface impact and noise play an important role.Gear oil is an important lubricating oil prepared by adding petroleum lubricating oil base oil or synthetic lubricating oil, adding extreme pressure antiwear agent and oiliness agent.Used in various gear transmissions to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life and improve the efficiency of power transmission.The hyperbolic tooth surface load is as high as 2942MPa. In order to prevent the tooth surface from being worn and scratched by oil film rupture, extreme pressure antiwear agents are often added to the gear oil.
- What are the reasons for the broken shaft of the reducer when it is not concentric?Some users have broken the output shaft of the drive motor after the equipment has been running for several months.Checked the cross-section of the output shaft of the drive motor and found that it was almost exactly the same as the cross-section of the output shaft of the reducer.The outer ring of the cross-section is brighter, and the color of the cross-section becomes darker toward the axis, and finally it is broken at the axis.This fully shows that the main reason for the broken shaft of the output shaft of the drive motor is that the motor and the reducer are not concentric during assembly.When the concentricity is guaranteed to be very good when the motor and the reducer are assembled, the output bearing of the motor is only subjected to rotational force, and it will run smoothly.However, when it is not concentric, the output shaft has to bear the radial force from the input end of the reducer. The long-term action of this radial force will force the output shaft of the motor to bend, and the direction of bending changes continuously with the rotation of the output shaft.Every time the output shaft rotates one revolution, the direction of the lateral force changes 360 degrees.If the concentricity error is large, the radial force will increase the temperature of the output shaft of the motor, and its metal structure will
