<p>(1) the input end of the reducer rotation and the output does not rotate, or significantly lower than the normal speed of rotation This situation is mainly due to the internal transmission components of the reducer out of the question, mostly gear broken or broken shaft. This fault can only be solved by removing the reducer to replace the corresponding parts.</p>
<p>(2) reducer input and output can not rotate, there are two ways to repair this situation: First, the input motor or motor reverse observation is feasible, as appropriate repair or replacement; Second, deceleration check reducer ( Internal bearing damage caused by failure to run) to replace the corresponding parts.</p>
<p>(3) Reducer noise and vibration is significantly higher than the normal cause may be due to loosening of the connecting bolt or reducer effective positioning failure, or oil temperature is too high, the oil is dirty. For the structure of the planetary gear reducer, the shell is generally connected by bolts to the next box, two inner ring gear, the box, a ring gear and the upper cover connected as a whole. Between the connecting parts are generally through the internal and external stop with the way to achieve the radial reducer positioning. In order to ensure the reliability of the positioning of two adjacent parts, with the mouth is often very tight, difficult to remove. Is to ring gear (see photo) as an example of the structure of the demolition process.</p>
