3. Incoming Quality Control
To establish the AQL acceptable level of incoming material control, to provide the material for the whole inspection, sampling, immunity. On the acceptance of qualified products to warehousing, substandard goods to take return, check, rework, rework inspection; responsible for tracking bad, to monitor the supplier to take corrective measures
to prevent recurrence.
4. Process Quality Control
The manufacturing site of the first examination, inspection and final inspection, sampling according to the requirements of some projects, judging the quality change trend;
found abnormal phenomenon of manufacturing, and supervise the production department to improve, eliminate the abnormal phenomenon or state.
5. FQC(Final QC)
After the manufacturing department will complete the product, stand in the customer’s position on the finished product quality verification, in order to ensure the quality of
customer expectations and needs.
6. OQC(Outgoing QC)
After the product sample inspection to determine the qualified, allowing storage, but when the finished product from the warehouse before the formal delivery of the goods, there is a check, this is called the shipment inspection.Check content:In the warehouse storage and transfer status to confirm, while confirming the delivery of the product
is a product inspection to determine the qualified products.

蜗轮减速器齿轮比的计算
蜗轮减速器的齿轮比由蜗轮（也称蜗杆）的齿数和蜗杆轴的螺纹数决定。蜗轮减速器的齿轮比公式为：
齿轮比 = 蜗轮齿数 / 蜗杆螺纹数
例如，如果蜗轮有 60 个齿，蜗杆轴有一根螺纹，则齿轮比为 60:1。
It’s important to note that worm reducers have an inherent self-locking property due to the angle of the worm threads. As a result, the gear ratio also affects the mechanical advantage and the system’s ability to resist backdriving.
计算齿轮比时，务必确保蜗轮减速器设计合理，且齿轮比符合您应用所需的机械特性。此外，选择蜗轮减速器的齿轮比时，还应考虑效率、负载能力和速度限制等因素。
蜗轮蜗杆减速机与螺旋齿轮减速机：对比分析
Worm gearboxes and helical gearboxes are two popular types of gear systems, each with its own set of advantages and disadvantages. Let’s compare them:
| 方面 | 蜗轮箱 | 螺旋齿轮箱 |
| 效率 | 由于蜗杆与蜗轮之间的滑动摩擦，效率降低。 | 由于螺旋齿轮齿之间的滚动接触，效率更高。 |
| 扭矩传递 | 单级即可实现优异的扭矩传递和高减速比。 | 扭矩传递性能良好，但高减速比可能需要多级减速。 |
| 噪声和振动 | 通常情况下，滑动操作会导致更高的噪音和振动水平。 | 由于滚动接触更顺畅，噪音和振动水平更低。 |
| 反弹 | 由于设计原因，固有反冲较大。 | 由于螺旋齿啮合，齿隙减小。 |
| 高速运转下的效率 | 由于效率损失，不太适合高速应用。 | 由于效率更高，更适合高速应用。 |
| 过载保护 | 天然的自锁功能提供了一定的过载保护。 | 可能不具备同等水平的固有过载保护能力。 |
| 应用程序 | 常用于需要高减速比的应用，例如输送系统和重型机械。 | 广泛应用于汽车变速器、工业机械等领域。 |
蜗轮蜗杆减速器和斜齿轮减速器在工程领域各有用途，具体选择取决于应用需求。蜗轮蜗杆减速器适用于高减速比的应用，而斜齿轮减速器则因其更高的效率和更平稳的运行而备受青睐。
在机械系统中采用蜗轮减速器的优势
蜗轮减速器具有诸多优点，使其适用于各种机械系统：
- 高减速比： 蜗轮减速器可提供显著的减速效果，因此非常适合需要高减速比而不需要多个齿轮的应用。
- 紧凑型设计： 蜗杆减速器设计紧凑，节省空间，因此可用于空间有限的应用场合。
- 自锁式： 蜗轮蜗杆减速器具有自锁特性，这意味着蜗杆可以防止蜗轮反转。这对于需要在没有外部制动机构的情况下保持负载位置的减速器应用非常有利。
- 运行平稳安静： 蜗轮蜗杆减速器通过齿轮间的滑动运动运行，与其他一些类型的减速器相比，运行更加平稳安静。
- 高扭矩传动： 蜗轮减速器能够传递高扭矩，因此适用于需要强大扭矩输出的应用。
- 散热： 蜗杆和蜗轮之间的滑动作用有助于散热，这在运行过程中会产生热量的应用中是有利的。
- 性能稳定： 蜗轮减速器性能稳定可靠，适用于各种工业和机械系统的连续运行。
Despite these advantages, it’s important to note that worm gearboxes also have limitations, such as lower efficiency compared to other gear types due to the sliding motion and potential for higher heat generation. Therefore, selecting the appropriate type of gearbox depends on the specific requirements and constraints of the application.
