PATENTSCHRIFTPATENT LETTERING
KLASSE 47: Maschinenelemente.CLASS 47: Machine elements.
Der Keil bietet sowohl am Kopf als auch am Fufs eine gleich grofse Auflagefläche für den Keilzieher dar, ist gänzlich verdeckt und kann sich beim Einführen in die Nuth nicht ecken bezw. festklemmen, so dafs die aufzukeilende Riemscheibe etc. nie schräg auf die Welle zu sitzen kommt.The wedge offers an equally large support surface for both the head and the foot represents the wedge puller, is completely covered and cannot be inserted into the groove corners or clamp so that the pulley to be wedged, etc. never at an angle to the Wave comes to sit.
Die Form des Keiles ist durch die Fig. 1 bis 3 dargestellt. Der Keil A, Fig. 1 und 2, ist ah seinen Enden mit zwei Nasen α und b versehen, welche genau gleich hoch, Fig. 3, aber etwas schmäler als der eigentliche Keilkörper sind. In die mit Anzug versehene Nuth c des letzteren wird noch eine schmälere Nuth als diese für die Einführung der am dünnen Ende des Keiles befindlichen Nase b eingearbeitet. Die Grundfläche dieser schmalen Nuth besitzt keinen Anzug, sondern läuft genau parallel mit der Mittellinie der Nabenbohrung, so dafs die Nase b beim Einführen des Keiles auf der Grundfläche der schmalen Nuth gleitet, wodurch die Riemscheibe etc. ihre richtige Lage auf der Welle erhalten mufs.The shape of the wedge is shown in FIGS. The wedge A, Fig. 1 and 2, is provided at its ends with two noses α and b , which are exactly the same height, Fig. 3, but slightly narrower than the actual wedge body. An even narrower groove than this for the introduction of the nose b located at the thin end of the wedge is worked into the groove c of the latter, which is provided with a suit. The base of this narrow groove has no suit, but runs exactly parallel to the center line of the hub bore, so that the nose b slides on the base of the narrow groove when the wedge is inserted, so that the pulley etc. must maintain its correct position on the shaft.
Die Nase b hat aufserdem noch den Zweck, den Keil beim Eintreiben desselben zu führen und die auf der Welle zu befestigende Riemscheibe etc. auf letzterer in die richtige Lage zu drehen, wenn die Nuthen oder die Nuth und Fläche nicht genau über einander stehen sollten.The nose b also has the purpose of guiding the wedge when it is driven in and turning the pulley etc. to be attached to the shaft into the correct position on the latter if the grooves or the grooves and surfaces are not exactly above one another.
An jedem Ende des Keiles sind die Ecken d . . . d desselben bis auf die Breite der Nasen um einige Millimeter zurückgesetzt, damit beim Eintreiben des Keiles durch den Keilzieher die auf ersteren übertragene Kraft möglichst genau in seiner Mittellinie und nicht an den Ecken wirkt, wie es bei Benutzung eines breiten Keilziehers vorkommt.At each end of the wedge are the corners d. . . d of the same set back to the width of the noses by a few millimeters, so that when the wedge is driven in by the wedge puller, the force transferred to the former acts as precisely as possible in its center line and not at the corners, as occurs when using a wide wedge puller.
Das Ende des hierzu erforderlichen Keilziehers B besitzt die durch die Fig. 4 dargestellte Form. Die beiden vorstehenden Zapfen e legen sich in die Ausschnitte d . . . d des Keiles und dienen nur als Führung, während die Kraft durch· den mittleren Theil des Keilziehers auf den Keil übertragen wird. Mit Hülfe dieses Keilziehers kann der Keil leicht ein- und ausgetrieben werden.The end of the wedge puller B required for this purpose has the shape shown in FIG. The two protruding pins e are placed in the cutouts d. . . d of the wedge and serve only as a guide, while the force is transmitted to the wedge through the middle part of the wedge puller. With the help of this wedge puller, the wedge can easily be driven in and out.
. Da der Keil in der Nabe gänzlich verborgen liegt, kann der Arbeiter beim Auflegen eines Riemens oder Behandeln der durch derartige Keile verbundenen Maschinentheile nicht erfafst werden, also auch nicht verunglücken.. Since the wedge is completely hidden in the hub, the worker can use a Belting or handling of the machine parts connected by such wedges will not have an accident either.
Die Nasen α und b können aufser der dargestellten rechteckigen jede andere der Beschaffenheit der Nabe des aufzukeilenden Maschinentheils entsprechende Form besitzen.The noses α and b can have any other shape corresponding to the nature of the hub of the machine part to be keyed, in addition to the rectangular one shown.
