Planetary gear reducer is a common industrial mechanical transmission device used to reduce speed, increase torque, and change the direction of motion. During operation, if the phenomenon of abnormal noise occurs, it may be caused by the following reasons:
1.Poor lubrication or lack of maintenance can lead to wear and abnormal noise. When the amount of oil is insufficient or the use of unsuitable grease can lead to increased friction and noise;At the same time, equipment that is not cleaned for a long time and replaced with new oil will produce carbon deposits and aggravate the wear and tear of parts.
2.Improper engagement of the planetary disc with the pinion is one of the causes of failure. For example, the manufacturing accuracy is not high, which leads to the distance between the centers of the two wheels being too far, which hinders the rotation and makes a sound. In order to avoid this, it is necessary to regularly check, adjust, assemble and re-correct machining deviations.
3.Pitting and gluing of pinions can also cause a rhythmic sound from the machine. This is due to the fact that both cases are caused by the heat generated by the ultra-high speed operation caused by the excessive load, which causes the destruction of the metal material. In order to avoid the recurrence of this problem, we should pay attention to the correct design and production process, and maintain it on time during work, and stop the machine in time to check and repair and replace the sound problem.
4.Another kind of behavior is the formation of abrasive particles on the tooth surface, this problem is mostly because the hard particles are embedded in the surface of the opposite surface, and the effect of gravity causes the shape of the opposite contact point to change, forming a sharp shear lip, and then causing early local fatigue damage, so it is necessary to ensure the quality before leaving the factory and reduce the output of unqualified products.
