I believe you are not unfamiliar with gears, but how much do you know about gear reducers? Want to know friends might as well follow Xiaobian to understand some of it.


After using the gear reducer for a period of time, there will be such and such problems. If the vibration of the gear reducer is too large, we should pay attention to it. What is the cause? Learn more about:


1. Excessive bearing wear


When the bearing works for a long time, the clearance of the bearing is too large or the imbalance occurs, which leads to the friction and heating of the bearing. It is afraid that the friction between the rotor and the stator will directly damage the bearing. The sliding bearing is more prone to vibration, because it has the viscous effect of lubricating oil, the shaft will float, and this is also related to the weight of the bearing. If the weight of the bearing is larger, the wear will be faster.


2. The base vibrates greatly


In some cases, the excessive vibration of the base also has an impact. The vibration frequency of the base can be said to be the speed of the gear reducer, which may lead to the unstable state in operation due to the design of the base.


3. Transmission motivation disorder


When the calibration line between the motor and the driver in the gear reducer is not good, it is easy to produce vibration. To adjust the calibration line, it is necessary to re install the connection between the driver and the motor, so as to stabilize the rotation of the motor bearing.


4. Unbalance of rotor machinery


The unbalance mentioned here refers to the unbalance of the rotor in the static state and the unbalance in the rotating state. The rotor deviates from the axis and produces deflection and abnormal vibration under the action of centrifugal force.


5. Loose rotor parts


Some parts of the motor rotor: commutator, magnetic pole, belt pulley, etc. these loose situations will also occur after the reducer has been used for a long time. Usually, this kind of situation occurs, and the rotor will have noise. These situations should be handled as soon as possible, because as time goes on, it will become more and more troublesome.
