Optimization of machining accuracy of gear blank

The machining accuracy of gear blank is very important for the final gear machining accuracy improvement. Therefore, in order to improve the machining accuracy of gears, it is necessary to guarantee the machining accuracy of gear blanks. In the process of gear blank processing, rib plate often appears some degree of asymmetry and imbalance. In addition, due to the design problems, the corresponding spokes will also have different degrees of deflection and center imbalance. Obviously, these problems will have a very adverse impact on the symmetry of the gear blank, and the final product will have different degrees of symmetry problems.

To a large extent, the asymmetry of gear blank has a very serious impact on the installation and processing of gears, which is also very unfavorable for the overall performance improvement of mechanical equipment. Therefore, in the actual processing process, on the one hand, it is necessary to fully ensure the processing of the outer circle and inner hole of the gear blank, on the other hand, it is also necessary to fully consider the influence of the tooth blank port on the web plate, so as to avoid the asymmetry problem in the processing process as far as possible, and improve the symmetry and processing accuracy of the gear blank. However, in the actual processing process, due to the influence of many factors, the effect of improving the machining accuracy of gear blank is still not very ideal. In view of this situation, the relevant technical personnel carried out a certain degree of optimization and improvement.

First of all, it is necessary to further improve the machining design of gears scientifically and reasonably, and operate in strict accordance with the corresponding design drawings. Secondly, in the process of gear blank processing, it is necessary to ensure the good fit between the outer circle of the gear and the corresponding end face, so as to reduce the corresponding wear. Among them, the most important thing is that in the process of gear cutting, it is necessary to ensure the coincidence of the outer circle motion track of the gear and the central shaft, on this basis, further ensure the unity of gear operation, and lay a solid foundation for the improvement of gear machining accuracy.
