Grooved Gasket Structure for Stable Cutter Holder Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gaskets in road milling machines fail to stabilize effectively between the cutter and chisel holder, limiting their buffering effect and leading to abrasion of the chisel holder due to high impact during the milling process.
Innovation Solution
A gasket design featuring a body with a through hole, covering portion, grooves, protruding ring, and extending portion is configured to securely attach to the chisel holder, increasing the contacting area and stability, and dispersing impact through grooves of varying depths, thereby preventing abrasion and enhancing the service life of the cutter and chisel holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gasket is used between the cutter and chisel holder, then the buffering effect is limited, but the installation stability is insufficient
Solution Approach 1:
The gasket body is divided into multiple functional regions: a covering portion for coverage, at least one groove for engagement, a protruding ring for positioning, and an extending portion for attachment. This segmentation allows each region to perform its specific function, improving both installation stability and buffering effect independently.
Solution Approach 2:
The groove is formed within the gasket body, creating a nested structure where the groove engages with the chisel holder. This nested configuration enhances the buffering capability by providing a recessed area that absorbs impact while maintaining stable installation through the engagement geometry.
2Ease of manufacture
If the gasket is designed with simple structure, then the manufacturing is easy, but the frictional contact area is insufficient
Solution Approach 1:
The gasket features localized structural elements (groove, protruding ring, extending portion) that concentrate frictional contact at specific areas rather than distributing it uniformly. This local quality enhancement increases the effective frictional contact area with the chisel holder while maintaining overall structural simplicity and ease of manufacturing.

AI summary
A gasket (100) includes a body (110), a through hole (120), a covering portion (130), at least one groove (141, 142), a protruding ring (150) and an extending portion (160). The body includes a cutter surface (111) facing towards the cutter and a holder surface (112) opposite to the cutter surface. The through hole penetrates the body, and the through hole has an axial direction (X1). The covering portion surrounds the body and protrudes outwards from the holder surface along the axial direction, and the covering portion has a covering thickness (h1) relative to the holder surface. The at least one groove is disposed at the holder surface and located between the covering portion and the through hole. The protruding ring protrudes from the holder surface and located between the covering portion and the at least one groove. The extending portion is located at the holder surface, protrudes from the holder surface, and surrounds the through hole.
