During the use of the indexer, abnormal sounds often occur. It should be noted that the mechanical transmission, due to the friction between the components, there will be some noise, but if the sound becomes a loud noise, then It is the problem of the product itself.
In the automation system, the cam indexer is used for intermittent transmission. When an abnormal sound occurs, it is necessary to first determine where the source of the sound comes from, because in actual operation, abnormal noise will also appear in the motor, or split. When the source of the main sound is generated from the indexer, it is necessary to first judge the use of the indexer.
Through three aspects of analysis, for the newly used or used indexer, after the abnormal sound, the indexer is placed in the no-load state, start the motor, the abnormal sound in this case, indicating the split The initial assembly and debugging of the device are not in place, and the pre-pressing of the tapered bearing is too tight, causing abnormal noise in the friction of the contact surfaces between the components. For a small indexer, the indexer is rotated by hand when the motor is removed. If the input shaft cannot be rotated or is more laborious, then the internal components need to be re-adjusted.
In the abnormal noise generated by the use of the cam indexer, to confirm whether the load exceeds the rated load of the indexer, it is necessary to re-confirm the initial selection data and perform the internal operation of the indexer while ensuring the load is OK. confirm. All machines are the same, they have to go through a running-in period, and there must be an adaptation and matching process before the perfect transmission.
Some indexers will make abnormal noise after one year of use. It is necessary to check and maintain the indexer to confirm whether there is looseness between the components. Whether it is within the scope of initial maintenance, the cooling oil in the indexer box needs to be replaced. After the inspection and maintenance, there is still abnormal noise. Then, it is necessary to look at the wear of the divider member, check whether the transmission cam and the needle are damaged or deformed, and the wear of the turret and other components should be replaced in time. Damaged parts. When the cam indexer produces abnormal noise, it is recommended to return to the production factory for inspection and maintenance, so as to facilitate professional maintenance of the product.
