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.

Adjusting Gear Ratio in a Variable Gearbox
In a variable gearbox, adjusting the gear ratio is typically achieved through mechanisms like Continuously Variable Transmissions (CVTs). CVTs use various designs, such as pulleys with adjustable diameters or expanding/contracting belts, to vary the effective gear ratio continuously. By changing the effective diameters of the pulleys or the distance between the belt’s contact points, the gear ratio can be adjusted smoothly, allowing the engine to operate at its most efficient speed under different load conditions. Other variable transmission systems may use different principles, but the goal is to provide seamless and continuous adjustment of the gear ratio.
Suitability of Variable Gearboxes for High-Torque Applications
Variable gearboxes can be suitable for high-torque applications depending on their design and capabilities:
Some variable gearboxes, such as hydrostatic transmissions, are well-suited for heavy machinery and vehicles that require high torque at low speeds. These gearboxes use hydraulic systems to transmit power and can provide substantial torque output.
However, it’s essential to consider the specific design and construction of the variable gearbox. High-torque applications may require specialized components, robust construction, and efficient cooling systems to manage the heat generated during operation.
Hydrostatic variable gearboxes, for instance, can offer high torque at low speeds but may not be as efficient for high-speed applications due to their design limitations.
Ultimately, the suitability of a variable gearbox for high-torque applications depends on factors such as the gearbox’s design, the nature of the application, and the desired performance characteristics.
Variable Gearbox: Function and Operation
A variable gearbox is a transmission system that allows for continuously adjustable gear ratios, enabling optimal power transfer across various speeds. It employs mechanisms like CVTs (Continuously Variable Transmissions) or e-CVTs (Electronically Controlled CVTs) that use belts, pulleys, or gears to maintain a seamless range of gear ratios without discrete shifts. This design offers smooth acceleration, improved fuel efficiency, and adaptive performance. By altering the effective gear ratio based on the engine’s power and vehicle’s speed, a variable gearbox ensures the engine operates within its optimal efficiency range, enhancing overall driving experience and efficiency.
