用聚晶立方氮化硼刀片精加工表面淬火的螺旋伞齿轮,质量标准达到了AGMA12～13,而且还淘汰了费用高、工时长的磨削和抛光工序。过去是先在软的齿轮毛坯上切出齿,经淬火或表面淬火,然后用磨削或抛光精加工。精加工的且的是减少齿形和齿距偏差,即减少周节变化和周节误差来提高齿轮的总体精度。齿轮总体精度和光洁度的提高,使它的负荷能力(传递扭矩)和寿命也相应提高。这是因为齿的啮合图形更大,更加均匀,因而载荷分布更平稳,且减少了载荷磨损;此外,提高齿的光洁度也有助于改善齿轮的性能。
Polycrystalline cubic boron nitride blade surface finish quenching spiral bevel gear, quality standards reached AGMA12 ~ 13, but also out of high cost, long working hours of grinding and polishing processes. In the past, the teeth were first cut on a soft gear blank, hardened or surface-hardened, and then finished with grinding or polishing. Finished and is to reduce the tooth profile and pitch deviation, that is, to reduce the cycle changes and the pitch error to improve the overall accuracy of the gear. The overall accuracy and finish of the gear increase so that its load capacity (transmission torque) and life expectancy increase accordingly. This is due to the larger, more uniform tooth engagement pattern, resulting in smoother load distribution and reduced load wear; in addition, improved tooth finish also helps to improve gear performance.
