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.
7. Certification.

蜗轮减速机的自锁特性
是的，蜗轮蜗杆减速器具有自锁特性，这在某些应用中非常有利。自锁是指当系统静止时，机构能够防止运动从输出轴传递回输入轴的能力。由于蜗轮和蜗杆的独特设计，蜗轮蜗杆减速器本身就具有自锁特性。
自锁特性源于蜗杆轴上的螺旋角。在设计合理的蜗轮蜗杆传动装置中，蜗杆的螺旋角能够产生机械优势，从而抵抗反向运动。当传动装置未被主动驱动时，蜗杆螺纹与蜗轮齿之间的摩擦力会产生锁定效应。
This self-locking feature makes worm gearboxes particularly useful in applications where holding a load in position without external power is necessary. For instance, they are commonly used in situations where there’s a need to prevent a mechanism from backdriving, such as in conveyor systems, hoists, and jacks.
However, it’s important to note that while self-locking properties can be beneficial, they also introduce some challenges. The high friction between the worm gear and worm wheel during self-locking can lead to higher wear and heat generation. Additionally, the self-locking effect can reduce the efficiency of the gearbox when it’s actively transmitting motion.
When considering the use of a worm gearbox for a specific application, it’s crucial to carefully analyze the balance between self-locking capabilities and other performance factors to ensure optimal operation.
蜗轮蜗杆所用材料
蜗轮蜗杆采用多种材料制造，以满足不同的应用需求。蜗轮蜗杆的常用材料包括：
- 钢： 钢材因其强度高、经久耐用和耐磨性好，是蜗轮蜗杆的常用材料。它能承受重载，常用于工业领域。
- 青铜： 青铜具有良好的润滑性，常用于蜗轮蜗杆部件。它具有有效的耐磨性，尤其适用于对运行噪音要求较高的应用。
- 铸铁： Cast iron is known for its high strength and durability. It’s often used for worm gears in applications where shock loads or heavy-duty conditions are expected.
- 铝： 铝制蜗轮重量轻、耐腐蚀，因此适用于对减轻重量要求较高的应用场合。
- 塑料： 有些蜗轮蜗杆由尼龙或聚甲醛等塑料材料制成。选择这些材料通常是因为它们具有自润滑性能和运行噪音低。
- 复合材料： 复合材料兼具多种性能，例如轻质和耐腐蚀性，因此适用于特定的应用领域。
The choice of material depends on factors such as the application’s load, speed, operating environment, and required performance characteristics. It’s important to consider these factors when selecting the appropriate material for worm gears to ensure optimal performance and longevity.
防止蜗轮蜗杆变速箱出现反冲
蜗轮蜗杆传动装置的反冲会导致精度降低、定位误差增大以及整体效率下降。以下是防止或最大限度减少反冲的步骤：
- 高品质组件： 使用制造公差严格的高质量蜗轮蜗杆和蜗轮。精密部件有助于减少反冲。
- 正确网格划分： 确保蜗轮和蜗杆正确对齐并啮合。啮合不当会导致齿隙增大。
- 预加载： 对蜗轮施加少量预紧力有助于减少齿隙。但是，过大的预紧力会增加摩擦和磨损。
- 防反弹机制： 考虑使用防反冲机制，例如弹簧加载系统或可调节垫片，来补偿任何固有的反冲。
- 润滑： 适当的润滑可以减少摩擦，并有助于最大限度地减少反冲。使用具有良好油膜强度和减少磨损的润滑剂。
- 维护： 定期检查和维护变速箱，以便发现并解决随着时间的推移出现的齿隙变化。
It’s important to strike a balance between reducing backlash and maintaining smooth operation. Consulting with gearbox experts and following manufacturer guidelines will help you optimize your worm gearbox’s performance while minimizing backlash.
