PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf einen Schmiermittelprüfapparat, bei dem ein Dampfölgemisch innerhalb eines hermetisch abgeschlossenen Gehäuses zwischen einer festen und einer sich drehenden Fläche verrieben wird.The invention relates to a lubricant testing apparatus in which a steam oil mixture within a hermetically sealed housing between a fixed and a self rotating surface is rubbed.

Um einen durchaus beweiskräftigen Versuch über den Schmierungsgrad der Schmieröle durchzuführen, ist es unerläßlich, daß derselbe unter den gleichen Bedingungen unternommenA thoroughly conclusive experiment on the degree of lubrication of the lubricating oils it is essential that it be undertaken under the same conditions

to wird, denen die Öle in der Dampfmaschine selbst unterworfen sind, und nur bei Innehaltung dieser Bedingungen wird die erfolgte Prüfung eines Öles vollkommen und entscheidend sein, so daß es zur Schmierung der Maschinenzylinder verwendet werden kann.to, to which the oils in the steam engine itself are subjected, and only when pausing Under these conditions, the completed test of an oil becomes perfect and decisive so that it can be used to lubricate the machine cylinder.

Vorliegender Schmiermittelprüfapparat, welscher den gestellten Anforderungen entspricht, besteht im wesentlichen aus zwei sehr harten Stahlkegel ventilen, die untereinander durchThe present lubricant testing device, which meets the requirements, consists essentially of two very hard steel cone valves that pass through each other

ao ein Universalkniegelenk verbunden sind und auf Sitzen aus Phosphorbronze drehen, in welchen ein Satz regulierbarer Kanäle vorgesehen ist, die zwischen den beiden Ventilen eine Expansionskammer schaffen, wobei das Reibungssystem in einen starkwandigen Zylinder mit Dampfmantel eingelassen ist, zum Zwecke, das Schmiermittel den praktischen Versuchsbedingungen anzupassen, d. h. solches in Berührung mit gesättigtem Dampfe, gleichviel welchen Druckes, oder mit überhitztem Dampfe bei beliebiger Temperatur unter vollem I Drucke oder bei veränderlicher Expansion zu bringen.ao a universal knee joint are connected and Rotate on phosphor bronze seats in which a set of adjustable channels is provided that create an expansion chamber between the two valves, with the friction system in a thick-walled cylinder with steam jacket is embedded, for the purpose of making the lubricant practical Adapt test conditions, d. H. such in contact with saturated vapor, no matter what pressure, or with superheated steam at any temperature under full I. To bring prints or with variable expansion.

Auf beiliegender Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform beispielsweise veranschaulicht, und zwar zeigt Fig. ι den senkrechten Schnitt des Apparates und Fig. 2 die Draufsicht auf die obere Reibscheibe. The subject matter of the invention is shown in one embodiment, for example, in the accompanying drawing illustrates, namely Fig. ι shows the vertical section of the apparatus and FIG. 2 shows the plan view of the upper friction disk.

Die Vorrichtung umfaßt zwei Kegelreibscheiben 1 und 2 aus sehr hartem Stahl, die untereinander vermittels eines Kniegelenkes 3 verbunden sind und sich auf Phosphorbronzesitzen 4 bzw. 5 drehen. Die Reibscheiben werden in Lagern 6 geführt, was mit der Kegelförmigkeit der Scheiben eine genaue Zentrierung der durch den Motor angetriebenen Welle 7 sichert.The device comprises two conical friction disks 1 and 2 made of very hard steel, which are connected to each other by means of a knee joint 3 and sit on phosphor bronze Turn 4 or 5. The friction disks are guided in bearings 6, which, with the conical shape of the disks, ensures precise centering the shaft 7 driven by the motor secures.

Genanntes Reibungssystem ist in einen starkwandigen Gußzylinder 8 eingelassen, der einem Drucke bis zu 15 Atm. widerstehen kann und in welchem ein Dampfeinlaß 9, ein Dampfmantel 10 sowie eine AuspufEkammer 11 vorgesehen sind.Said friction system is embedded in a thick-walled cast cylinder 8, the a pressure of up to 15 atm. can withstand and in which a steam inlet 9, a Steam jacket 10 and an exhaust chamber 11 are provided.

Der Zylinder 8 wird von einem Dom 12 abgeschlossen, der mit einem Thermometer 13, einem Manometerstutzen 14 und einem Ölzuführungsrohr 15 versehen ist. Die Scheibe 1 (Fig. 2) besitzt eine geeignete Anzahl Kanäle 16, welche man im Bedarfsfalle vermittels Schrauben 17 oder auf andere geeignete Weise abschließen kann. Genannte Kanäle entspre-The cylinder 8 is closed by a dome 12, which is connected to a thermometer 13, a pressure gauge port 14 and an oil supply pipe 15 is provided. The disc 1 (Fig. 2) has a suitable number of channels 16, which you can if necessary by means of screws 17 or in another suitable manner can complete. The named channels correspond to

Claims

Chen a provided in the seat 4 channels 18, for the purpose of between the two Slices 1 and 2 to create an expansion chamber that can be regulated as required. The disc 2

has a channel 19, which is a channel 20 of the seat 5, which supplies the steam and oil mixture to the expansion chamber 11, from where it is routed to a condenser.

The dome 12, designed as a cover, is attached to the cylinder 8 by means of strong bolts 22, which ensure the system a perfect seal and allow access to the panes for their adjustment.

The operation of the device is as follows:

The steam enters the device through the inlet 9, is through the butt plate 21 distracted and acts under full

Pressure on the disk 1. Then the steam flows through the channel 16 and that 18 into the expansion chamber, where it acts on the disc 2 and finally occurs through channels 19 and 20. the

The sample of oil subjected to the test passes through the tube 15 of a pressure lubrication device to, is thrown by the shaft 7 and then lubricates through the. Channel 18 den Seat 4, then the seat 5 and enters through the

Channels 19 and 20 together with the steam as a steam oil mixture to pass in a condenser to be collected.

The steam jacket 10 has the purpose of avoiding the loss of heat, or else, in the event that the apparatus is used for other experiments, the oils on the different temperatures required depending on the test.

The apparatus described is placed on the base of the whole and by means of a the shaft 7 actuating auxiliary motor moves. A precision apparatus allows the slightest Detect changes in the tension and density of the steam lubricant mixture.

If three-phase power is available, the shaft 7 can be rigidly attached to the rotor attach the machine, which is then arranged without bearings in the armature; in this Trap one has an apparatus that absolutely not every one for the measurement relevant friction eliminated.

It goes without saying that the various parts that make up the device can be modified, without departing from the principle of the invention.

Godfather τ-An saying:

Lubricant testing apparatus in which a steam oil mixture is hermetically sealed within a enclosed housing is rubbed between a fixed and a rotating surface, characterized by two by means of the universal knee joint (3). interconnected cone valves (1, 2), which rotate on seats (4, 5) in which a set of adjustable channels (16 to 20), the creation of a steam expansion chamber between said two valves allow is provided.
