Divided Sealing Ring Jig With Guided Press-Fit Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proper attachment of a divided sealing ring to an annular groove in a rod head is a difficult operation, lacking specific measures to enhance operation efficiency.
Innovation Solution
A jig for press-fitting a divided sealing ring, comprising a first and second rod head with an annular groove defined by a projection and recess, and including a sleeve and plunger for guiding the sealing ring into position, with positioning engagement regions and adjustable parts for various diameters, facilitates easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a divided sealing ring is used to enable replacement without disassembling the fluid transmission apparatus, then maintenance time and cost are reduced, but the attachment operation becomes difficult and time-consuming
Solution Approach 1:
The patent introduces a jig as an intermediary tool that mediates between the divided sealing ring and the rod head. The jig includes a guide portion that guides the sealing ring onto the rod and a press-fitting portion that applies force to secure the sealing ring in the annular groove, making the attachment process simple and intuitive without requiring complex disassembly procedures
Solution Approach 2:
The jig performs preliminary actions by pre-positioning the divided sealing ring segments and guiding them into the correct orientation before final installation. The guide portion of the jig prepares the sealing ring by aligning it with the rod head's annular groove, ensuring proper positioning before the press-fitting operation begins
2Device complexity
If no specific attachment measures are provided for divided sealing rings, then device complexity is reduced, but operation efficiency deteriorates
Solution Approach 1:
The jig is segmented into distinct functional portions: a guide portion for positioning and aligning the sealing ring, and a press-fitting portion for applying installation force. This segmentation allows each component to perform its specific function efficiently while keeping the overall device structure simple and easy to understand
Solution Approach 2:
The jig serves as a simple intermediary device that bridges the gap between the sealing ring and rod head without adding complex mechanisms. It provides the necessary guidance and force application in a straightforward manner, improving operation efficiency while maintaining device simplicity

AI summary
In a jig for press-fitting a divided sealing ring, while a sleeve is attached to a first rod head, a guide region leading to a recess is defined between an inner circumferential surface of the sleeve and a rod. When a divided sealing ring attached to an outer circumferential surface of the rod is press-fitted to a prescribed position in the recess by passing the divided sealing ring through the guide region by using a plunger, positioning engagement regions engaged with each other are provided between the sleeve and the plunger.
