Disk-Saw Cutting Tooth Mounting for Stable Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting cutting teeth to disk-saw felling heads are inefficient, relying on threaded bolts which may not securely hold the cutting teeth in place during rotation, potentially leading to instability and reduced cutting performance.
Innovation Solution
A cutting tooth system with first and second protrusions that fit into a receiving portion on the disk-saw felling head, secured by corresponding retaining devices, allowing for stable rotation and effective chip removal, featuring a chip removal path and cutting edge configuration for enhanced cutting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded bolts are used to mount cutting teeth to the disk, then the mounting method is simple and widely applicable, but the cutting teeth may not be securely held in place during rotation, leading to instability
Solution Approach 1:
The cutting tooth is divided into multiple protrusions (first protrusion, second protrusion, etc.) that fit into corresponding recesses in the disk. This segmentation allows each protrusion to be independently secured by retaining devices, distributing the securing function across multiple points rather than relying on a single threaded bolt connection.
Solution Approach 2:
The retaining devices are pre-configured on the disk at the locations where protrusions will be positioned. This preliminary arrangement ensures that when cutting teeth are mounted, the retaining devices are already in place to securely hold the protrusions, eliminating the need for complex threaded fastening operations during installation.
2Stability of the object's composition
If multiple protrusions and retaining devices are used to secure cutting teeth, then stability during rotation is improved, but the device complexity increases
Solution Approach 1:
Multiple retaining devices are integrated into a unified mounting system where each retaining device works in conjunction with the others to secure different protrusions of the cutting tooth. This merging creates a cohesive securing mechanism that provides enhanced stability without requiring each component to be independently complex.
Solution Approach 2:
Each retaining device is positioned at a specific location on the disk corresponding to a particular protrusion of the cutting tooth. This local positioning allows each retaining device to be optimized for its specific function of securing that particular protrusion, providing targeted stability where needed most during rotation.

AI summary
A cutting tooth system for a disk of a disk-saw felling head. The disk defines a receiving portion and an axis of rotation. The cutting tooth system comprises at least one cutting tooth. The cutting tooth comprises a first portion defining a first protrusion and a second protrusion. The first portion is configured to be received in the receiving portion for rotation with the disk. A second portion defines a chip removal path and a cutting edge adjacent the chip removal path. A first retaining device is configured to couple to the disk to secure the first protrusion in the receiving portion. A second retaining device is configured to couple to the disk to secure the second protrusion in the receiving portion.
