Description

Befestigungsvorrichtung für die Filmtransportrolle Die Erfindung betrifft eine Einrichtung zur Befestigung einer FihntransportrolIe auf ihrer Achse. Bekannterweise wird die Rolle mittels einer Schraube befestigt, die in die Achse eingeschraubt wird und mit ihrem Kopf gegen einen Bund der Rolle drückt. Zur sicheren ,Mitnahme der Rolle und zum Schutze gegen etwa eigenmächtiges Verdrehen derselben auf ihrer Achse hat man Mitnehmerscheiben angewendet, die mit einer Nase teilweise in Schlitze der Transportrolle und der Transportrollenachse eingreifen.Film Transport Roller Attachment Device The invention relates to a device for fastening a FihntransportrolIe on its axis. Well known the roller is fastened by means of a screw that is screwed into the axle and presses her head against a collar of the roll. For safe, take along the role and to protect against unauthorized twisting of the same on their Axis one has used drive plates with a nose partially in slots the transport roller and the transport roller axle engage.

Es hat sich nun gezeigt, daß eine derartige Befestigung insofern ungünstig ist, als der Schraubenkopf direkt gegen den Bund der Transportrolle gepreßt wird. Laufen nämlich diese beiden Flächen und das Gewinde der Schraube nicht ganz genau zueinander,, so wird die Transportrolle auf der Achse verdrückt, wodurch dann die Rolle schief auf der Achse sitzt und der Zahnkranz nicht mehr exakt läuft. Zu diesem Zwecke läßt man nun nicht mehr den Schraubenkopf selbst gegen die l\Etnehmerscheibe drükken, sondern schaltet zischen die Mitnehmerscheibe und den Schraubenkopf eine Feder (Glockenfeder oder Spiralfeder) ein. Dadurch werden eventuelle Unregelmäßigkeiten an der Mitnehmerscheibe oder an dem Schraubenkopf selbsttätig ausgeglichen. Die Befestigung der Transportrolle kann entweder nach der geschilderten Art und Weise mittels einer gewöhnlichen Schraube geschehen, oder sie kann auch mittels eines Konus, der in die teilweise geschlitzte Transportrollenachse eingeschraubt wird, befestigt werden.It has now been shown that such a fastening is unfavorable in this respect is when the screw head is pressed directly against the collar of the transport roller. This is because these two surfaces and the thread of the screw do not run exactly to each other ,, so the transport roller is pushed on the axis, which then the The roller is crooked on the axle and the ring gear no longer runs exactly. To this For this purpose, one no longer lets the screw head itself against the retaining washer press, but switches between the drive plate and the screw head Spring (bell spring or spiral spring). This will remove any irregularities automatically balanced on the drive plate or on the screw head. the Attachment of the transport roller can either be as described done by means of an ordinary screw, or it can also be done by means of a Cone, which is screwed into the partially slotted transport roller axis, be attached.

In der Abb. i ist die erfindungsgemäße Befestigung der Filmtransportrolle i mittels einer einfachen Schraube z und Glockenfeder 3, in .In Fig. I is the inventive attachment of the film transport roller i by means of a simple screw z and bell spring 3, in.
