在祖国工业大跃进的形势下,适合于高精度、高速度、高效率,且运转平稳的螺旋伞齿轮传动,日益广泛地在机器制造业的各种机械传动中应用着。但该种齿轮的制造,需要有专用设备,且生产效率较低,因此在一般厂矿企业中,往往成为生产中的薄弱环节。我厂也是如此。为了改进这种情况,在 Under the situation of great leap forward in the motherland, helical bevel gears suitable for high precision, high speed, high efficiency and smooth operation are increasingly used in various mechanical transmissions in the machine manufacturing industry. However, the manufacture of the gear requires special equipment and low production efficiency. Therefore, it is often the weak link in the production of general plant and mining enterprises. My factory is also true. In order to improve this situation,
