- Use the reducer correctly to avoid unnecessary lossesThe reducer will be used in many industries, but for those who don't know about the reducer, we still don't know what problems the reducer will encounter in the application process.How do we deal with these problems? Today, Dongchen Xiaobian will introduce to you: First, the reducer should be used for low-speed applications, the speed does not exceed 1000 rpm, and the suitable range is 1000 to 3000 PPS (0.9 degrees).It can be operated through a reduction gear.The motor has high efficiency and low noise.Do not use the entire step state of the reducer, and the vibration is large in the entire step state.For loads with a large moment of inertia, a motor with a large frame size should be selected.When the motor is under high-speed or large inertia load, it generally does not start at the working speed, but gradually increases the frequency to increase the speed. One motor does not lose its step, and the second time can reduce noise and improve the positioning accuracy of the stop.For high precision, it should be solved by mechanical deceleration, increase the motor speed, or use high-resolution drive
- The reducer can use the above method to check the working performanceJudging from the sound: when the reducer is running, different sounds will appear, indicating that the reducer has different conditions. We can judge whether the reducer is good or bad by hearing, but if we need accurate judgment, we still need a sound detector specially used to check the reducer. I

- How to reduce the noise of reducerThe problem of high noise of reducer has always been an inevitable problem of many mechanical equipment. The noise is caused by the operation of mechanical equipment and is inevitable. Therefore, noise has always been a "unsolvable" problem. However, although the noise is inevitable, we can try our

- What are the characteristics of reducer lubricating oil?1. Good wear resistance. Wear resistance refers to the ability of reducer lubricating oil to form and maintain an oil film on the friction surface between moving parts, prevent metal from contacting each other, and reduce wear.The anti-wear performance of reducer lubricating oil mainly depends on oiliness and extreme pressure (resistance).Oiliness refers to the ability of gear oil to absorb on the friction surface of parts to form an oil film to reduce friction and wear.Usually we say that the good oiliness of gear oil means that it has strong adsorption capacity and can improve the ability to resist wear.Extreme pressure refers to the performance of preventing damage to the friction surface such as sintering and gluing under the extremely high pressure lubrication conditions where the contact pressure of the friction surface is very high and the oil film is prone to rupture. It is also called the carrying capacity.2. Viscosity and viscosity-temperature properties The lubricating oil of the reducer must have suitable viscosity and good viscosity-temperature properties.Generally speaking, the use of high-viscosity lubricating oil is beneficial to prevent damage to parts and reduce noise, while transmission efficiency, cooling effect and oil transfer performance, etc.
- Several common causes of oil leakage after the reducer oil sealSome 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 motor output shaft, and its metal
- Precautions for installation and operation of reducer1. The installation position of the reducer should ensure the operation of the staff, including easy access to the cursor, vent plug and oil drain plug.After the installation of the reducer is completed, the inspector should comprehensively check the accuracy of the installation position in order to determine the reliability of each fastener.2. The fixation of the reducer is very important. To ensure stability and firmness, generally speaking, we should install the reducer on a horizontal foundation or base. At the same time, the oil in the oil drain tank should be able to be drained, and the cooling air circulation should be smooth.If the fixation of the reducer is not good and the foundation is unreliable, there will be vibrations, vibrations, etc., and unnecessary damage to the bearings and gears.3. When installing the reducer, special attention should be paid to the alignment of the transmission center axis, and the alignment error should not exceed the compensation amount of the coupling used in the reducer.After the reducer is aligned according to the requirements, a more ideal transmission effect and a longer service life can be obtained.4.
