Description

Spannschlauch 12 aufgezogen ist. Fig.2 zeigt die Spannhülse 11, die durch Schlitze 13 elastisch und dehnbar istTensioning hose 12 is pulled up. Fig.2 shows the Clamping sleeve 11, which is elastic and stretchable through slots 13

Nachdem die — nicht dargestellten — Werkstücke im Abstand voneinander auf den Spannschlauch 12 aufgebracht worden sind, wird dieser durch Druckluft gespannt, die aus dem Ventil 9 durch die Bohrung 10 den Druckraum 8 füllt, den Druckschlauch 5 und den Spannschlauch 12 aufbläst sowie die Spannhülse 11 dehnt Nach dem Spritzvorgang wird die Vorrichtung durch Ablassen· der Luft mittels des Ventils 9 wieder entspanntAfter the workpieces (not shown) have been placed on the clamping hose 12 at a distance from one another have been applied, this is tensioned by compressed air, which from the valve 9 through the bore 10 fills the pressure space 8, inflates the pressure hose 5 and the clamping hose 12, as well as the clamping sleeve 11 stretches After the spraying process, the device is opened by releasing the air using the Valve 9 relaxed again

The invention relates to a device for eliminating intermediate disks.

As an application process, ben- and synchronizer rings must remain relatively low in 35. spraying is used in many cases. In order to stiffen the clamping hose, it is further proposed that the rings with intermediate washers be smaller, the pressure chamber stretched and metallized in packets over a metallic diameter, "slotted clamping sleeve and a pressure to surround the hose especially during the subsequent separation. The It is also recommended that the ring broke the coating material on the ring channel, because then the more stressed tension would break out, since the diaphragm washers, especially in the case of ring hose, can be easily replaced with eccentric deflection after its wear and tear, and can be difficult to center. without that the whole Spannvorrichsind and must be about renewed processing to the outer periphery of an intermediate. the clamping sleeve has DA r rule disc spillage of molding material mechanically in a circular or ovality of the 'must be removed by impact.
