轮杆减速器输人端加装一个斜齿轮减速器，构成的多级减速器可获得非常低的输出速度，是斜齿轮级和蜗齿级的组合，比纯单级双输出轴蜗杆减速机具有更高的效率。而且振动小，噪音低，能耗低。
In short, the hollow shaft worm reducer is easy to install, reasonable in structure, reliable and durable.Of course, you should also pay attention to choosing the grade of the reducer. The powerful company will adopt the design points according to the design of the reducer, the layout of the heat dissipation ribs, the calculation of heat balance, the design of the oil circuit, and the actual use and operating conditions of the reducer. The manufacturing process produces high-quality, reliable and durable reducers.As long as users use and maintain them correctly, they can get satisfactory results.
1减速机发热和漏油。双输出轴蜗杆减速机为了提高效率，一般均采用有色金属做蜗轮，蜗杆则采用较硬的钢材，由于它是滑动磨擦传动，在运行过程中，就会产生较高的热量，使减速机各零件和密封之间热膨胀产生差异，从而在各配合面产生间隙，而油液由于温度的升高变稀，容易造成泄漏。主要原因有四点，一是材质的搭配是否合理，二是啮合磨擦面的表面质量，三是润滑油的选择，添加量是否正确，四是装配质量和使用环境。2蜗轮磨损。蜗轮一般采用锡青铜，配对的蜗杆材料一般用45钢淬硬至HRC45一55,还常用40C:淬硬HRC50一55，经蜗杆磨床磨削至粗糙度RaO.8fcm,减速机正常运行时，蜗杆就象一把淬硬的锉刀，不停地锉削蜗轮，使蜗轮产生磨损。一般来说，这种磨损很慢，象某厂有些减速机可以使用10年以上。如果磨损速度较快，就要考虑减速机的选型是否正确，是否有超负荷运行，蜗轮蜗杆的材质，装配质量或使用环境等原因。3传动小斜齿轮磨损。一般发生在立式安装的减速机上，主要跟润滑油的添加量和润滑油的选择有关。立式安装时，很容易造成润滑油油量不足，当减速机停止运转时，电机和减速机间传动齿轮油流失，齿轮得不到应有的润滑保护，启动或运转过程中得不到有效的润滑导致机械磨损甚至损坏。
4 Worm bearing is damaged.When the reducer fails, even if the reduction box is well sealed, the factory often finds that the gear oil in the reducer has been emulsified, and the bearings have been rusted, corroded, and damaged. This is because the gear oil is It is caused by the condensation of moisture generated after the heat becomes cold; of course, it is also closely related to the quality of the bearing and the assembly process.
