What Are The Common Treatment Methods For Reducer Noise?

The reason why the reducer produces noise is mainly due to the friction, vibration and collision of the transmission gear. How to effectively reduce and reduce the noise and make the reducer more in line with environmental protection requirements is also a key research topic at home and abroad.


Reducing the gear transmission noise during the operation of the reducer has become an important research topic in the industry. Many scholars at home and abroad regard the change of gear tooth meshing stiffness in gear transmission as the main factor of gear dynamic load, vibration and noise. Use the method of shape modification to minimize the dynamic load and speed fluctuation to achieve the purpose of reducing noise. This method has proved to be a more effective method in practice. However, with this method, the process requires shaping equipment, which is often impossible for the majority of small and medium-sized factories.


After years of research, some scholars have proposed that by optimizing gear parameters, such as modification coefficient, tooth height coefficient, pressure angle, center distance, etc., to minimize the impact velocity of engagement, the ratio of the impact velocity of engagement and the impact velocity of engagement is at For a certain value range, the gear design method that reduces or avoids the impact of the meshing pitch circle can significantly reduce the gear noise of the reducer.

1. When installing the reducer, you should face up to the center axis of the transmission, and the error should not be greater than the compensation amount of the coupling used. Good alignment can prolong the service life and obtain ideal transmission efficiency.


2. When the transmission part is installed on the output shaft, do not use a hammer to strike it. Usually the assembly fixture and the internal thread of the shaft are used to press the transmission part in with bolts, otherwise it may cause damage to the internal parts of the reducer. It is best not to use a rigid fixed coupling, because improper installation of this type of coupling will cause unnecessary external loads, which will cause early damage to the bearing, or even break the output shaft in severe cases.


3. The reducer should be firmly installed on a stable level foundation or base, the oil in the oil drain groove should be drained, and the cooling air cycle should be smooth. The foundation is unreliable, which will cause vibration and noise during operation, and cause damage to bearings and gears. When the transmission coupling has protrusions or adopts gears or sprockets for transmission, it should be considered to install protective devices. When the output shaft bears a large radial load, the reinforced type should be selected.


4.The installation is carried out according to the defined standard, which can ensure that the staff can conveniently approach the oil mark, vent plug and oil drain plug. After the device is in place, the correctness of the device position and the reliability of the pressing of the fasteners should be checked in order, and it should be able to roll flexibly after the device is installed. The reducer adopts oil pool splash lubrication. Before operation, the user needs to remove the screw plug of the vent hole and replace the vent plug. Check the height of the oil level line by opening the oil level plug screw according to different device positions. Add oil from the oil level plug until the lubricating oil overflows from the oil level plug screw hole. Load trial run, the time shall not be less than 2 hours. The operation should be stable, and there should be no shock, vibration, noise and oil leakage. Any abnormality should be eliminated in time. After a certain period of time, the oil level should be checked again to prevent possible leakage from the casing. If the ambient temperature is too high or too low, the grade of the lubricant may be changed.

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
