What Are The Causes And Solutions Of Reducer Fever?

When the reducer is in normal operation, due to the loss of efficiency, part of the input power will be converted into heat energy, making the internal temperature of the reducer rise, if the temperature is too high, it will cause damage to the internal parts. Therefore, the pre-selection and checking of reducer should meet the requirements of thermal power.


Cause of reducer fever:


1. Possible causes: reducer overload operation, bearing wear, improper assembly of bearings, gears, shafts and other parts, too high or too low voltage, too much start and stop in a short time, poor lubrication, etc.


2. In steel rolling production, excessive load operation may cause frequent failures of multiple reducer, and bearing wear is common.


3.Abnormal heating of the reducer refers to the serious heating of the bearing part or shell part of the reducer, which is beyond the normal temperature range. The most common is the heating of the bearing part.

gear reducers


Solutions:


1. Water-cooled coil is installed at the bottom of the gear box and through the cooling water pipeline, which can effectively increase the thermal conductivity. Under the different flow velocity and flow rate of cooling water, the cooling effect of the coil tube has been tested for many times. The results show that the cooling effect of the coil tube is directly related to the flow rate and flow rate of cooling water. However, due to the limitation of the installation space in the reducer box, the winding length of the disk tube can not be very long, so its cooling effect is limited. The advantages are simple structure, convenient installation, better heat dissipation effect and easy serialization.


2. External lubrication means that a water cooling or air cooling device is set outside the reducer to cool the lubricating oil in the reducer, and the lubricating oil after cooling is returned to the reducer for lubrication. This kind of cooling is mainly used for high power cooling or high ambient temperature. The advantages are good cooling effect and long lubricating oil life. The disadvantage lies in the increase of control points, increasing the probability of accidents.


3.Fan heat dissipation Using fan heat dissipation is simple and easy to operate. However, the disadvantage of fan cooling method is that it is not suitable for some situations. For example, when cooling the gear box in underground coal mine, the use of fan will seriously pollute the surrounding working environment and mechanical equipment, and it uses radiation heat exchange, so the heat loss is also limited.

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?

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
