Abstract

A saw blade includes saw teeth arranged along a toothed side. The saw teeth have a pitch that increases from a clamped end of the saw blade to a saw blade tip. The saw teeth include a tooth support and a hard metal tooth joined to the tooth support. The saw teeth have a plurality of tooth supports having the same shape. Larger tooth spaces are provided for the increasing pitch between tooth supports having an identical shape.

First claim

The invention claimed is:

1. A saw blade, comprising:
a clamping end;
a saw blade tip; and
saw teeth arranged along a toothed side of the saw blade, the saw teeth having an increasing pitch from the clamping end to the saw blade tip,
wherein each of the saw teeth includes a tooth support and a hard metal tooth joined to the tooth support,
wherein several tooth supports have the same geometric size and shape, and
wherein the several tooth supports having the same geometric size and shape define larger tooth gaps therebetween for the increasing pitch.

2. The saw blade as claimed in claim 1 , wherein several saw teeth are combined to form one tooth group, and wherein the saw teeth within the one tooth group have a constant pitch.

3. The saw blade as claimed in claim 1 , wherein several consecutive saw teeth define increasing tooth gaps therebetween.

4. The saw blade as claimed in claim 1 , wherein each of the saw teeth includes a tooth root and a tooth tip, and wherein a space between the tooth root and the tooth tip is identical in all the saw teeth.

5. The saw blade as claimed in claim 4 , wherein the geometry of the tooth gaps in the region of the tooth root is in the shape of a graduated circle.

6. The saw blade as claimed in claim 1 , wherein all the tooth supports have the same geometry.

7. The saw blade as claimed in claim 1 , wherein the tooth supports adjacent to the tooth tip have a tooth bed with a receiving surface for receiving the hard metal tooth.

8. The saw blade as claimed in claim 7 , wherein the receiving surface on the tooth bed has a geometry in the shape of a graduated circle.

9. The saw blade as claimed in claim 1 , wherein the hard metal teeth are welded onto the tooth support.

10. The saw blade as claimed in claim 1 , wherein the hard metal teeth are joined to the tooth support by brazing.

11. The saw blade as claimed in claim 1 , further comprising:
a blade support.

12. The saw blade as claimed in claim 11 , wherein the blade support includes the toothed side, on which the saw teeth are arranged.

13. The saw blade as claimed in claim 11 , wherein the saw teeth are arranged between the clamping end of the saw blade and the saw blade tip.

14. The saw blade as claimed in claim 12 , wherein each of the tooth supports is realized in one piece with the blade support.

15. The saw blade as claimed in claim 1 , wherein a distance between a tooth root and a corresponding tooth tip of each of the saw teeth is constant.
