Solution Overview
Problem
Conventional braided sealing rings have weak joints that compromise their strength and sealing performance, leading to reduced service life and potential safety hazards in high-temperature, high-pressure environments, particularly in large power equipment and industrial facilities.
Innovation Solution
A jointless braided sealing ring with a multi-layer structure where each braided ring layer is continuously sleeved onto the previous one, eliminating interruptions and using a defining ring within the structure to ensure accuracy and prevent deformation, along with specialized equipment for production that includes a braiding spindle and adjustable density mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional braided sealing rings are produced by cutting and joining sections, then production is feasible and simple, but the joint areas create weak points that reduce strength and sealing performance
Solution Approach 1:
The patent implements continuous braiding without interruption by using a movable support device that allows the braiding machine to continuously form the sealing ring in a circular path. The braided fibers are laid continuously around the circumference, eliminating the need to cut and join sections, thus removing weak joint points while maintaining manufacturing feasibility through automated continuous operation
Solution Approach 2:
The support device is designed to be movable along the braiding direction, allowing dynamic adjustment during the braiding process. This enables the system to accommodate the continuous formation of the sealing ring without fixed constraints, facilitating seamless continuous production while maintaining control over the braiding process
2Reliability
If joints are used to connect sealing sections, then production can be completed in discrete steps, but the joint areas create apparent inconsistencies that affect sealing performance
Solution Approach 1:
The braiding process operates continuously without interruption to form the complete sealing ring. The support device moves continuously to allow uninterrupted laying of braided fibers, ensuring uniform structure throughout the entire ring without joint areas that would create sealing inconsistencies
Solution Approach 2:
The sealing ring production is segmented into continuous circular passes around the support device. Each pass contributes to the complete ring formation, and the process can be controlled in manageable stages while maintaining overall continuity, balancing process controllability with seamless structure formation
3Duration of action of stationary object
If multiple discrete sections are joined to form the sealing ring, then production flexibility is maintained, but the number of joints increases which reduces service life
Solution Approach 1:
The sealing ring is formed in a single continuous braiding operation without cutting or joining sections. The support device enables continuous production of the complete ring in one uninterrupted process, eliminating joints that would reduce service life while maintaining high production efficiency through automated continuous operation
Solution Approach 2:
The joining operation is completely extracted from the production process. Instead of producing discrete sections and joining them, the system directly produces the complete sealing ring in one continuous operation, removing the joining step entirely and its associated weak points

AI summary
A jointless braided sealing ring as well as a method and a special machine for producing such a sealing ring are disclosed. The braided sealing ring adopts a multi-layers braided structure comprising a number of continuously sleeved ring layers arranged from inside to outside. The innermost braided ring layer is used as a core. The tail end of the first braided ring layer (1) is sleeved on the starting end of the first braided ring layer (1) and serves as the starting end of the second braided ring layer (2) to implement continuously braiding without any interruption. The second braided ring layer (2) is sleeved on the first braided ring layer (1) and the third braided ring layer (3) is sleeved on the second braided ring layer (2). The Nth braided ring layer (4) is sleeved on the (N-1)th braided ring layer (5). N braided ring layers have (N-1) continuous intact braided ring layers. The tail end (8) of the outermost braided ring layer is superposed with the starting end (7) of the innermost braided ring layer. Service life and sealing effect of the braided sealing ring are increased. A perimeter-defining ring (6) is provided in the sealing ring to improve the dimensions precision of sealing ring, and avoid that the sealing ring deforms during braiding and trimming.
