日本长冈齿轮制造厂试制成功一种特殊形状的球面齿轮。若将球面齿轮装在轴与轴之间的联轴器上,就能高效地传递动力。同时还将齿顶试加工成凹球面,并与球面齿轮相啮合。这种齿轮具有普通齿轮所没有的特征,正在进行基础性试验。目前,许多国家都在研究、制造球面齿轮,有些国家在有关文献中介绍了一些球面齿轮的设计图,但没有实际加工和使用实 Japan Nagaoka gear factory trial success of a special shape of the spherical gear. If the spherical gear mounted on the coupling between the shaft and shaft, you can efficiently transfer power. At the same time will be addendum processing into concave spherical surface, and meshing with the spherical gear. This kind of gear has the characteristic that ordinary gear does not have, is carrying on the foundation test. At present, many countries are studying and manufacturing spherical gears. Some countries have introduced some designs of spherical gears in the relevant literature, but there are no actual machining and actual use
