Integrated Seal Ring Protector for Clean Shaft Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting oil seal rings in vehicle transmission components during assembly are costly, prone to damage, and allow contaminants to enter, with separate components causing assembly difficulties and design constraints.
Innovation Solution
An integrated protection component comprising a plug and annular element with a bayonet joint, made from synthetic plastic, that engages with the sealing ring to prevent damage and contaminants, featuring weakened zones for easy opening and a conical surface for precise alignment, allowing for a single, efficient assembly and protection mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate protection plug and PTFE ring are used to protect the sealing ring, then the sealing ring is protected from damage, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines the protection plug and PTFE ring into a single integrated protection component. The protection element is formed as one piece with the PTFE ring, eliminating the need for separate components while maintaining both protection functions. This resolves the contradiction by reducing device complexity and assembly difficulty while preserving the reliability of sealing ring protection.
Solution Approach 2:
The integrated protection component serves multiple functions simultaneously: it acts as both a protection plug to prevent contaminant entry and a PTFE ring to guide the transmission shaft. By combining these functions into a single universal component, the patent reduces the number of parts needed while maintaining comprehensive protection of the sealing ring.
2Reliability
If multiple separate components are used for protection, then comprehensive protection is achieved, but assembly time and cost increase
Solution Approach 1:
By merging the protection plug and PTFE ring into a single integrated component, the patent reduces the number of assembly steps. Instead of installing two separate components, the integrated protection component is installed as one unit, significantly reducing assembly time while maintaining comprehensive protection through its multi-functional design.
3Object-affected harmful factors
If the through-opening is closed with a plug before shaft assembly, then contaminants are prevented from entering, but the shaft or plug may damage the sealing ring lips
Solution Approach 1:
The integrated protection component acts as an intermediary between the shaft and sealing ring. The PTFE ring portion provides a smooth guiding surface that mediates the interaction between the shaft and sealing ring, allowing the shaft to pass through without directly contacting and damaging the sealing lips, while the protection plug portion prevents contaminant entry.
Solution Approach 2:
The patent changes the material parameter of the protection element by using PTFE (polytetrafluoroethylene), which has low friction and high wear resistance properties. This material parameter change allows the protection component to prevent contaminant entry while minimizing damage to the sealing ring lips during shaft assembly.

AI summary
An integrated protection component for a sealing ring and associated sealing system for a vehicle transmission component, including a plug that can be inserted inside the sealing ring and an annular element for protecting the sealing ring during insertion of a rotating shaft is provided. The annular element includes a flange-shaped end and a tubular side wall that directly comes into engaging contact with the sealing ring and receives inside it the rotating shaft. The first end being provided with a handle, the plug engaging in a removable manner with the annular element and the tubular side wall being provided with a first weakened zone formed longitudinally alongside a second, radially formed, weakened zone of the first end so as to break following a pulling force exerted manually on the handle.
