In the process of gear machining, it is often affected by geometric eccentricity and motion eccentricity, and causes corresponding gear machining error. Generally speaking, the main reason for the geometric eccentricity is that the axis of the ring gear does not coincide well with the central axis of the gear blank, while the main reason for the motion eccentricity is the offset between the axis of theand the central shaft.
In order to eliminate the influence of geometric eccentricity and motion eccentricity on gear machining accuracy, the relevant technical operators need to take all-round consideration, and make corresponding improvement and optimization according to the actual situation, so as to ensure the effective improvement of gear machining accuracy.
First of all, it is necessary to ensure the center positioning accuracy of the gear blank. Secondly, the bias caused by geometric eccentricity and motion eccentricity should be offset scientifically and reasonably. On the one hand, the movement eccentricity of the gear can be reasonably estimated by measuring the direction, and some methods can be taken to reduce the motion eccentricity in the subsequent design. On the other hand, it is necessary to accurately measure the longitudinal movement track of the gear blank, and make corresponding marks, so as to ensure the good operation of the gear in the actual installation process, and lay a good foundation for the improvement of gear machining accuracy.
