Saw Tooth Insert Structure for Continuous Cutting Edge Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saw teeth designs leave unprotected areas between inserts, leading to premature wear and degradation, and adverse effects on cutting performance due to 'wash-out' issues.
Innovation Solution
A saw tooth design featuring angled cutting edges with hardened inserts and transitional members that form a continuous cutting surface, providing enhanced protection and mitigating wear by creating a seamless cutting edge around the periphery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If flat triangular carbide inserts are used to protect the saw tooth body, then the cutting edge protection is improved, but gaps between adjacent inserts expose the saw tooth body creating weakened areas
Solution Approach 1:
The cutting edge protection is divided into multiple segments: hardened inserts at the corners and transitional members along the sides. This segmentation allows each component to be optimized independently while collectively providing complete coverage, eliminating the gaps that caused structural weakness in previous single-piece insert designs
Solution Approach 2:
The invention merges multiple protection elements (corner inserts and side transitional members) into a unified cutting edge protection system. The transitional members bridge the gaps between corner inserts, creating a continuous protective barrier that combines the strengths of both corner and side protection without leaving exposed areas
2Duration of action of stationary object
If hardened inserts are used to extend the life of the tooth and saw blade, then the duration of action is improved, but unprotected areas between inserts cause premature wear and degradation
Solution Approach 1:
The transitional members create a continuous hardened protective surface along the sides of the saw tooth body, eliminating interruptions or gaps in the protective coverage. This continuous protection ensures that the entire cutting edge, including previously exposed side areas, maintains its hardness and resistance to wear throughout the service life of the tooth
Solution Approach 2:
The invention applies different protective components to different locations: hardened inserts at the corners where maximum stress occurs, and transitional members along the sides. This localized approach ensures that each area receives the appropriate level and type of protection needed for its specific functional requirements
3Productivity
If traditional inserts are used to protect cutting edges, then the cutting performance is improved, but wash-out areas adversely affect cutting performance
Solution Approach 1:
The transitional members merge with the corner inserts to form a seamless, continuous cutting edge surface. This integration eliminates the wash-out areas that previously formed at the boundaries between inserts, creating a uniform cutting surface that maintains optimal cutting performance throughout the entire periphery of the saw tooth

AI summary
A saw tooth for a saw including a square saw tooth body to be mounted on a holder and for receiving inserts fastened to inwardly sloping seating surfaces on the cutting end of the tooth body. The inserts are provided with cutting edges. Between seating surfaces, the cutting end of the tooth body defines recesses for receiving intermediate members fastened therein. The intermediate members are provided with cutting edges, and the intermediate members abut the adjoining inserts to form a cutting surface about the periphery of the cutting end of the saw tooth and help protect the saw tooth body from damage including washout.
