The ring gear and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill. In order to ensure their reliable operation, in addition to strengthening the daily maintenance and regular maintenance, the installation and alignment of the ring gear and pinion are also important.
ring gear mating surface detection
After the ring gear is closed to the cylinder according to the installation mark, tighten the connecting bolts on the mating surface, and check whether there is a step on the side of the gear (the step is required to be as small as possible, otherwise it will affect the end runout of the ring gear). Use a feeler gauge of 0.04mm to check the matching condition. It is required that the insertion depth is not more than 50mm, and the cumulative length of the gap is not more than 1 / 4 of the tooth width.
