Abstract

The circular saw blade has different tooth tip circles. the tooth division (t1) in front of the high teeth (2) is smaller than the tooth division (t2) in front of the low teeth (3), where t2 is at least 10% greater than t1. If there are more than two tooth heights, the division before the front lowest tooth should be the greatest and the other divisions should be roughly the same.

Description

Es sind Kreissägen bekannt, bei denen jeder zweite Zahn einen etwas geringeren Flugkreis aufweist, um dadurch bei kleinen Vorschüben nicht zum Eingriff zu kommen und damit bei diesen Vorschüben die schneidende Zähnezahl zu halbieren zur Reduzierung der Schnittkräfte. Bei großen Vorschüben schneiden dann alle Zähne, jedoch mit sehr unterschiedlichen Vorschüben pro Zahn. Bei einer Zahnhöhendifferenz ΔH ist der Unterschied des Vorschubs pro Zahn 2ΔH, wodurch eine relativ große Zähnezahl erforder­ lich ist, um die hohen Zähne nicht zu überlasten, wobei die niedrigen Zähne relativ wenig schneiden und einen großen Schabezonenbereich haben.Circular saws are known in which every second tooth has a somewhat smaller flight circle, so that it does not interfere with small feeds and thus halve the number of teeth cutting on these feeds to reduce the cutting forces. With large feeds, all teeth cut, but with very different feeds per tooth. With a tooth height difference ΔH, the difference in feed per tooth is 2 ΔH, which means that a relatively large number of teeth is required so as not to overload the high teeth, the low teeth cutting relatively little and having a large scraping zone area.

Der Erfindung liegt die Aufgabe zugrunde, eine Säge zu schaffen, deren Zähnezahl geringer ist bei gleicher Maximalbelastung und deren Vorschub pro Zahn der niedrigen Zähne größer ist und einen kleineren Schabebereich aufweist.The invention has for its object to provide a saw whose The number of teeth is lower with the same maximum load and their feed per tooth of the lower teeth is larger and a smaller scraping area having.

Das erfindungsgemäße Sägeblatt weist eine Zahnung auf mit unterschied­ lichen Zahnflugkreisen und mit unterschiedlicher Zahnteilung dergestalt, daß die Zahnteilung vor den hohen Zähnen kleiner ist als die Zahnteilung vor den niedrigen Zähnen.The saw blade according to the invention has teeth with a difference tooth flight circles and with different tooth pitch, that the tooth pitch in front of the high teeth is smaller than the tooth pitch before the low teeth.

Die einzige Figur zeigt den Sägenausschnitt (1) mit den hohen Zähnen (2) und den niedrigen Zähnen (3) mit der Zahnhöhendifferenz (ΔH) und der Zahnteilung vor den hohen Zähnen (t1) und der Zahnteilung vor den niedrigen Zähnen (t2) und die Transportzähne (4). The single figure shows the saw cut-out ( 1 ) with the high teeth ( 2 ) and the low teeth ( 3 ) with the tooth height difference (ΔH) and the tooth division in front of the high teeth (t1) and the tooth division in front of the low teeth (t2) and the transport teeth ( 4 ).
