What Are The Common Faults Of The Gear Reducer,Gearboxes,Speed Reducer?

1. Wear and tear of the reducer bearing chamber


It also includes the wear of the housing bearing box, the inner bore bearing chamber of the box, and the gearbox bearing chamber. This situation is mainly caused by the improper adjustment of the parallelism and coaxiality of the shafts when installing the shafts and bearings; in the process of long-term operation Deflection force (radial or axial) or abnormal vibration of the box body appears in the process, causing the shaft and bearing to be stressed to a certain degree of wear on the bearing chamber.


2. The shaft diameter of the gear shaft of the reducer is worn


The main wear parts are the shaft head, keyway, etc. The reason for this kind of failure is the frequent overload start and the material problem of some parts during operation.

3. The bearing position of the drive shaft of the reducer is worn or the bearing is faulty


Incorrect assembly will not only accelerate the wear of the bearing, but also breakage and high-temperature seizure. Especially for bearings that cannot be self-aligning; poor machining accuracy or improper installation of the journal or bearing seat hole, and too much shaft deflection will cause the inner and outer rings of the bearing to tilt each other, resulting in uneven distribution of the bearing load. The stress concentration will be destroyed prematurely.


4. Leakage on the joint surface of the reducer


Oil leakage is manifested in the joint surface of the reduction case body and the bearing end cover, mainly due to leaks in the joint surface sealing gasket or sealing compound application process; improper maintenance process; during equipment maintenance, due to the removal of dirt on the joint surface Incomplete, improper selection of sealant, reverse installation of seals, and failure to replace seals in time will cause oil leakage; this can be avoided after strengthening the assembly process requirements.


5. Gear tooth failure of reducer


Common forms of gear tooth failure include: broken gear teeth and damage to the tooth surface. Gear tooth fracture generally occurs at the tooth root, because the bending stress at the tooth root is the largest and there is stress concentration; the damage of the tooth surface can be divided into fatigue pitting of the tooth surface, abrasive wear, gluing and plastic deformation.


Measures to prevent gear tooth failure include: increasing tooth surface hardness and surface roughness requirements; choosing lubricants with higher viscosity; supplying enough lubricating oil and keeping the lubricating oil clean; avoiding frequent starts and severe overload and impact; improving assembly Quality and strengthen maintenance management.

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...
