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.

Calculating Gear Ratio in a Worm Reducer
The gear ratio in a worm reducer is determined by the number of teeth on the worm wheel (also known as the worm gear) and the number of threads on the worm shaft. The gear ratio formula for a worm reducer is:
Gear Ratio = Number of Teeth on Worm Wheel / Number of Threads on Worm Shaft
For example, if the worm wheel has 60 teeth and the worm shaft has a single thread, the gear ratio would be 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.
When calculating the gear ratio, ensure that the worm reducer is properly designed and that the gear ratio aligns with the desired mechanical characteristics for your application. Additionally, consider factors such as efficiency, load capacity, and speed limitations when selecting a gear ratio for a worm reducer.
Worm Gearbox vs. Helical Gearbox: A Comparison
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:
| Aspect | Worm Gearbox | Helical Gearbox |
| Efficiency | Lower efficiency due to sliding friction between the worm and worm wheel. | Higher efficiency due to rolling contact between helical gear teeth. |
| Torque Transmission | Excellent torque transmission and high reduction ratios achievable in a single stage. | Good torque transmission, but may require multiple stages for high reduction ratios. |
| Noise and Vibration | Generally higher noise and vibration levels due to sliding action. | Lower noise and vibration levels due to smoother rolling contact. |
| Backlash | Higher inherent backlash due to the design. | Lower backlash due to meshing of helical teeth. |
| Efficiency at Higher Speeds | Less suitable for high-speed applications due to efficiency loss. | More suitable for high-speed applications due to higher efficiency. |
| Overload Protection | Natural self-locking feature provides some overload protection. | May not have the same level of inherent overload protection. |
| کاربردها | Commonly used for applications requiring high reduction ratios, such as conveyor systems and heavy-duty machinery. | Widely used in various applications including automotive transmissions, industrial machinery, and more. |
Both worm and helical gearboxes have their place in engineering, and the choice between them depends on the specific requirements of the application. Worm gearboxes are preferred for applications with high reduction ratios, while helical gearboxes are chosen for their higher efficiency and smoother operation.
مزایای استفاده از کاهنده سرعت حلزونی در سیستمهای مکانیکی
گیربکسهای حلزونی مزایای متعددی دارند که آنها را برای سیستمهای مکانیکی مختلف مناسب میکند:
- نسبت کاهش دنده بالا: گیربکسهای حلزونی کاهش سرعت قابل توجهی را فراهم میکنند و آنها را برای کاربردهایی که نیاز به نسبت کاهش دنده بالا بدون نیاز به دندههای متعدد دارند، ایدهآل میکنند.
- طراحی جمع و جور: کاهندههای حلزونی طراحی جمع و جور و کم حجمی دارند که به آنها امکان استفاده در کاربردهایی با فضای محدود را میدهد.
- خود قفل شونده: گیربکسهای حلزونی خاصیت خود قفلشوندگی دارند، به این معنی که پیچ حلزونی میتواند از معکوس شدن حرکت چرخ حلزون جلوگیری کند. این ویژگی برای کاربردهایی که گیربکس نیاز به نگه داشتن بار در جای خود بدون مکانیسمهای ترمز خارجی دارد، مفید است.
- عملکرد روان و بیصدا: گیربکسهای حلزونی با حرکت لغزشی بین دندانهها کار میکنند و در مقایسه با برخی دیگر از انواع گیربکسها، عملکرد نرمتر و بیصداتری دارند.
- انتقال گشتاور بالا: گیربکسهای حلزونی میتوانند سطوح گشتاور بالایی را منتقل کنند و این آنها را برای کاربردهایی که نیاز به خروجی گشتاور قدرتمند دارند، مناسب میکند.
- اتلاف گرما: عمل لغزشی بین پیچ حلزونی و چرخ حلزون به اتلاف گرما کمک میکند، که میتواند در کاربردهایی که در حین کار گرما تولید میکنند، مفید باشد.
- عملکرد پایدار: کاهندههای حلزونی عملکرد پایدار و قابل اعتمادی ارائه میدهند که آنها را برای کار مداوم در سیستمهای مختلف صنعتی و مکانیکی مناسب میکند.
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.
