5. Perfect quality control process
5.1 Raw material inspection
All raw materials before warehousing must be tested, and the corresponding physical property report shall be issued,
and compared with the physical property report of raw materials. Only when the test values of the 2 physical property
reports are consistent, can they be warehoused.
5.2 Mold inspection
After mold development or cleaning, we will check the full size of the mold to ensure that the quality of each cavity is
the same.
5.3 Product inspection
In the process of product production, inspectors regularly inspect the semi-finished products to ensure the rationality
of the process and control the defective rate within a reasonable range.
5.4 Finished product inspection
The double inspection can ensure that the product appearance and size are 100% qualified.

Electrical Insulation in Jaw Couplings
Jaw couplings are designed to provide mechanical connection between two shafts while also maintaining electrical insulation. This feature is essential in applications where the connected shafts have different electrical potentials or where electrical isolation is required to prevent current flow between the shafts.
The electrical insulation in jaw couplings is primarily achieved through the use of non-conductive materials for the jaw components. The jaws of the coupling are typically made from materials such as elastomers or plastics, which are excellent electrical insulators. These non-conductive materials prevent electrical conduction between the two shafts, even if they are made from different conductive materials.
Additionally, the design of the jaw coupling ensures that the two shafts do not come into direct electrical contact with each other. The jaws of the coupling create a gap between the shafts, which further enhances the electrical insulation.
It’s important to note that while jaw couplings provide electrical insulation, their primary function is to transmit torque and accommodate misalignment between shafts. If specific electrical insulation requirements are critical for an application, additional measures such as insulating sleeves or shaft grounding may be necessary in conjunction with the jaw coupling.
Overall, jaw couplings are a reliable and widely used choice for mechanical power transmission while ensuring electrical isolation between connected shafts.
Can jaw couplings be used in servo motor and stepper motor applications?
Yes, jaw couplings can be used in both servo motor and stepper motor applications, and they are commonly employed in such systems. The key factors that make jaw couplings suitable for these motor types are their ability to handle misalignment, their torsional flexibility, and their compact and lightweight design.
In servo motor applications, jaw couplings are chosen for their high precision and responsiveness. Servo motors require couplings that can transmit torque with minimal backlash and provide accurate motion control. Jaw couplings achieve this by maintaining a tight fit between the elastomer spider and the coupling hubs, minimizing backlash and ensuring precise torque transmission. The elastomer spider also dampens vibrations and shocks, contributing to smoother motor operation and increased system stability. Additionally, the compact size and low inertia of jaw couplings make them ideal for high-speed servo motor applications where quick acceleration and deceleration are crucial.
In stepper motor applications, jaw couplings are preferred for their ability to handle misalignment. Stepper motors often have shaft misalignment due to manufacturing tolerances or other factors, and jaw couplings can accommodate both angular and parallel misalignment without imposing significant additional loads on the motor bearings. This helps to reduce wear and extend the life of the motor and coupling components. Moreover, stepper motors are commonly used in open-loop systems, where precise positioning and motion control are essential. Jaw couplings’ low backlash characteristics aid in achieving accurate positioning and eliminating any motion inaccuracies that might arise due to backlash in the coupling.
Overall, jaw couplings are well-suited for servo motor and stepper motor applications due to their precision, ability to handle misalignment, torsional flexibility, and low inertia. When selecting a jaw coupling for a specific motor application, it is essential to consider factors such as torque requirements, operating conditions, and motor specifications to ensure optimal performance and reliability in the system.
Types of Jaw Coupling Designs
Jaw couplings come in various designs to meet different application requirements. The main types include:
- One-Piece Jaw Coupling: This design consists of a single piece of material, typically made of steel or aluminum. It offers simplicity and compactness, making it suitable for light to medium-duty applications.
- Two-Piece Jaw Coupling: This design features two separate hubs with a flexible spider placed in between. The two-piece design allows for easier assembly and disassembly, making it convenient for maintenance and replacement of the elastomeric spider.
- Three-Piece Jaw Coupling: In this design, the coupling includes three parts: two hubs and an insert. The hubs are typically made of metal, while the insert is an elastomeric element (spider). Three-piece jaw couplings provide better damping of vibrations and are commonly used in applications where vibration isolation is crucial.
- Customizable Jaw Coupling: Some manufacturers offer customizable jaw couplings, allowing customers to choose different hub styles, materials, and spider hardness to tailor the coupling’s performance for specific applications.
Each design has its advantages and is selected based on factors such as torque requirements, misalignment compensation, and ease of maintenance.
