What Are The Reasons For The Bearing Damage Of The Reducer?

1. The bearing cavity is not cleaned or the grease added is not clean. For example, the tiny rigid material in the bearing cage is not completely cleaned up, and the bearing raceway is damaged during operation, causing excessive temperature rise to burn the bearing. Solution The gearbox cleaning and maintenance machine uses the original lubricating oil of the gearbox to clean the gearbox without adding any cleaning agent, which will not cause secondary pollution to the gear; the filtered oil can also be used again in low-end occasions to achieve Resource reuse.


2.Due to the excessively high operating temperature of the motor body and the lack of oil in the bearing and the lack of grease in the bearing in time, the bearing may even be burned.

3. Improper assembly of the bearing, such as unevenly knocking the inner ring of the bearing during cold assembly to cause the shaft to wear out, causing the inner ring of the bearing and the bearing to lose or reduce the amount of interference, and the phenomenon of running the inner ring occurs. When installing the motor end cover Uneven percussion results in a loose fit between the end cover bearing chamber and the outer ring of the bearing, causing the outer ring to run away. Either running the inner ring or the outer ring will cause the bearing's operating temperature to rise sharply and cause burnout, especially the failure of the inner ring will cause severe wear and bending of the rotating shaft. However, under normal circumstances, intermittent running of the outer ring will not cause the bearing temperature to rise sharply. As long as the bearing is intact, the phenomenon of intermittent running of the outer ring is allowed.


4. Due to the axial misalignment of the stator and rotor cores or the insufficient precision after re-machining the rotating shaft, the inner and outer rings of the bearing are not on the same cutting surface, which causes the temperature of the bearing to increase after it runs ""unusually"" until it burns.


5. Replace the bearing again. After the motor end cover is nested, the interference is too large or the ovality exceeds the standard, which causes the bearing ball clearance to be too small or uneven, which causes the friction to increase during the bearing operation, and the temperature rises sharply until it burns.


6. The bearing is damaged due to the mixed use of different types of grease.


7.The standby machine has not been operated for a long time, the grease has deteriorated, the bearing has rusted and has not been overhauled.

What Is A Induction Motor?

图片
Induction motor is also called ""asynchronous motor "", that is, the rotor is placed in a rotating magnetic field, under the action of the rotating magnetic field, a rotating torque is obtained, so the rotor rotates. The rotor is a rotatable conductor, usually in the shape of a squirrel cage. The stator is the non-rotating part of the motor, and its main task is to generate a rotating magnetic field. The rotating magnetic field is not realized by mechanical methods. Instead, alternating current is passed through several pairs of electromagnets to cyclically change the magnetic pole properties, so it is equivalent to a rotating magnetic field. This kind of motor does not have brushes or slip rings like DC motors. There are single-phase motors and three-phase motors depending on the type of AC used. Single-phase motors are used in washing machines, electric fans, etc.; three-phase motors are used as power for factories equipment. Working principle Through the relative...

Which Industries Do Servo Reducers Use More?

图片
Servo reducer is a new type of reducer with wide versatility. By virtue of its own advantages, it has been widely used in many industries. So do you know which industries need to use servo reducers? Servo reducers are needed in the following industries: 1. Machinery manufacturing industry In the mechanical transmission industry, the servo reducer is an intermediate device that connects the power source and the actuator. Usually, it uses the power of the electric motor, internal combustion engine and other high-speed operation through the small gear on the input shaft to mesh with the large gear on the output shaft to achieve the purpose of deceleration and transmit greater torque. For example, in the cement machinery industry, the servo reducer, as the second-largest general-purpose machinery and equipment to be used, will continue to rise with the strong demand of the cement machinery industry. 2. Industrial automation industry Servo reducer has the advantages of strong anti-overload ...

What Is A Servo Motor?How Does A Servo Motor Work?

What is a servo motor? The servo motor can also be called an executive motor, which is an executive component in an automatic control system. Its job is to convert the received electrical signal into an angular velocity output or an angular displacement output on the motor shaft. Servo motor classification There are two classifications of DC servo motor and AC servo motor. The main feature is that there is no rotation when the signal voltage is zero; the speed will drop at a uniform speed as the torque increases. DC servo motors are ideal for small applications, but they cannot handle large current surges. However, AC servo motors can cope with higher current surges and are widely used in industrial machinery. When it comes to price, DC motors are cheaper than AC servos, so they are used more. In addition, DC motors are specifically designed for continuous rotation, which makes them ideal for robot motion. How does a servo motor work? The working principle of the servo motor is relativ...
