The main drawback is that they spur gear will produce vibration. Whether due to the design, manufacture or deformation, etc., at the same time along the entire tooth surface may occur some changes involute shape. This will result in a regular, once per tooth incentive, it is often very strong. The resulting vibration caused by both large load on the gear, but also cause noise. Another negative point is that the contact time and sometimes additional strength by two pairs of meshing can not be obtained by the use of imported gear maintenance, because stress is circulating in single tooth meshing condition defined. Rolling overhaul, major inspection, adjustment and replacement; content maintenance work. Rolling replace the standard: the bearing needs to be replaced, we must first understand the cause of the failure, the extent of damage to the gear reducer repair, the impact on the use of, and then determine treatment measures depending on the circumstances. For bearing temperature is too high, the noise should be promptly shut down the big check processing. Found bearing damage, severe burns discoloration, cracks, etc. inside and outside the ring must be replaced. General requirements for equipment, bearings, although the injury is, but does not affect the use of the case may be intermittent operational requirements. For large and medium-sized gear overhaul disassembly time is not easy, so the gear maintenance procedures, in the event of significant damage when they overhaul, he may change from time to change, should be to replace as well.
