Description

Kinowiedergabemaschine mit Kühleinrichtung Die Erfindung betrifft eine neuartige Kühlung beispielsweise des Filmbahnträgers einer Kinowiedergabemaschine.Cinema playback machine with cooling device The invention relates to a new type of cooling, for example of the film carrier of a cinema playback machine.

Bisher verwandte man zur intensiven Kühlung Wasser, das durch den zu kühlenden Teil durchlief, wobei man die Rohrleitungen zur Kühlung des Werkes selbst zweckmäßig innerhalb des Gehäuses verlegte. Hierbei ist es jedoch nötig, große Sorgfalt auf die Abdichtung zu verwenden, damit nicht Wasser in das Schmieröl gelangt und beides eine Emulsion bildet, die nicht mehr genügend Schmierfähigkeit besitzt, worunter das Getriebe leiden muß.So far, water has been used for intensive cooling, which is transported through the The part to be cooled went through, whereby the pipelines for cooling the work went through even expediently laid within the housing. Here it is necessary, however, Great care should be taken with the seal so that water does not get into the lubricating oil and both form an emulsion that no longer has sufficient lubricity owns what the transmission must suffer from.

Es wird daher vorgeschlagen, den ö1-umlauf im Innern des Apparates so zu führen, daß das Schmieröl mit durch den zu kühlenden Fihnbahnträger oder durch andere zu kühlende und mit dem Film mittelbar oder unmittelbar in Berührung stehende Teile, die an sich einer ölschmierung nicht bedürfen, fließt, um so das Schmieröl gleichzeitig als Kühlmittel zu verwenden. Man erreicht dann noch den Vorteil, daß man eine besondere Wasserpumpe bzw. einen besonderen Anschluß an eine Druckwasserleitung ersparen kann, d. h. die Pumpe für die Umlaufölung wie für die Förderung des Kühlöls ist die gleiche. Bei derartiger Maßnahme sind keine Abdichtungsschwierigkeiten mehr zu überwinden.It is therefore suggested that the oil circulation inside the apparatus to lead so that the lubricating oil with through the train carrier to be cooled or through others to be cooled and directly or indirectly in contact with the film Parts that do not require oil lubrication flow, so does the lubricating oil to be used as a coolant at the same time. One then still has the advantage that a special water pump or a special connection to a pressurized water pipe can save, d. H. the pump for circulating oil as well as for pumping the cooling oil is the same. With such a measure there are no more sealing difficulties to overcome.

Um das Öl zu kühlen, kann an geeignetem Ort ein beliebiges Kühlaggregat vorgesehen werden:Any cooling unit can be used in a suitable location to cool the oil provided:
