Reversible Cutting Tooth Assembly for Rotary Cutters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary cutting machines with removable saw teeth face limitations in extending the life span and efficiency of cutting edges, as they typically have a fixed configuration and require frequent replacement or sharpening, which can be cumbersome and inefficient.
Innovation Solution
A reversible cutting tooth assembly for rotary cutting machines, featuring a tooth holder and a cutting tooth with opposed cutting faces that can be rotated 180 degrees to expose new cutting edges, allowing for extended use and improved operational efficiency by alternating the cutting faces as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional removable saw teeth with single cutting face are used, then the tooth can be easily replaced when cutting edges wear, but the tooth life span is limited and replacement frequency increases
Solution Approach 1:
The tooth is divided into two separate cutting faces, each with its own cutting edges. This segmentation allows one face to be used while the other is reserved for future use, effectively doubling the tooth's operational life and reducing replacement frequency.
Solution Approach 2:
Instead of replacing the entire tooth when cutting edges wear, the invention allows flipping the tooth over to use the opposite cutting face. This inversion approach extends tooth life without requiring immediate replacement or complex reconfiguration.
2Adaptability or versatility
If cutting teeth are made removable and rotatable, then cutting edge utilization is improved, but the device complexity increases
Solution Approach 1:
The tooth holder is designed with separate seating surfaces for two cutting faces, and the tooth itself is segmented into two faces with distinct cutting edges. This segmentation enables versatile cutting edge utilization while maintaining a relatively simple overall structure that doesn't require complex mechanisms.
3Productivity
If multiple cutting edges are provided on each face, then the productivity increases, but the manufacturing precision requirements increase
Solution Approach 1:
By providing multiple cutting edges on each of the two faces, the invention increases productivity through greater cutting edge availability. The segmentation into two faces with multiple edges each allows extended operational time before replacement is needed, while the manufacturing precision is managed through standardized tooth design.

AI summary
A cutting tooth assembly for a rotary cutting machine is described. The assembly includes a tooth holder adapted for mounting about the periphery of a rotating element of the rotary cutting machine, and a reversible cutting tooth, removably mounted to said tooth holder. The cutting tooth has opposed first and second cutting faces which are spaced apart along a central tooth axis extending therebetween. Each of the first and second cutting faces at least partially defines more than two cutting edges, and the cutting tooth is reversible by 180 degrees about a transverse tooth axis to dispose a selected one of the first and second cutting faces in an operable cutting position when mounted to the tooth holder.
