Opfindelsen vedrører en krumtapaksel til hermetiske kølekompressorer og med en lodret, rørformet del, der ved sin nedre ende bærer en rørformet hals, som har en øvre del, der er udformet som en ringformet bøsning, 5 som har elastiske segmenter med udvidede hoveder til tilvejebringelse af en snapforbindelse med den rørformede del, og en nedre del, der divergerer opad, således at smøremiddel fra kompressorhusets sump kan ansuges og transporteres gennem krumtapakslen til smøremiddelkana-10 ler, som er udformet i selve krumtapakslen.BACKGROUND OF THE INVENTION The invention relates to a crankshaft for hermetic refrigeration compressors and having a vertical tubular member bearing at its lower end a tubular neck having an upper portion configured as an annular sleeve having elastic segments with expanded heads to provide a snap connection with the tubular portion, and a lower portion that diverges upwardly so that lubricant from the sump of the compressor housing can be aspirated and transported through the crankshaft to lubricant channels formed in the crankshaft itself.
En krumtapaksel af denne type er kendt fra U.S.A. patentskrift nr. 4 209 080.A crankshaft of this type is known from U.S.A. U.S. Patent No. 4,209,080.
Ved denne kendte udformning udgøres halsen af plastmateriale af et rørformet stykke i to dele, en øv-15 re og en nedre, mellem hvilke der er en udvendig sekskantet krave. Den nedre del divergerer opefter og udgør selve halsen. Den øvre del er delt i længderetningen mod sin øverste ende i to modstående elastiske arme, der hver bærer en udvendig tand, der er placeret 20 diametralt modsat den anden tand. Kraven har to diametralt modstående fremspring på oversiden.In this known embodiment, the neck of plastic material is constituted by a tubular piece in two parts, an upper and a lower, between which there is an external hexagonal collar. The lower part diverges upward and forms the neck itself. The upper portion is divided longitudinally toward its upper end into two opposing elastic arms, each carrying an outer tooth located 20 diametrically opposite the other tooth. The collar has two diametrically opposed projections on the upper side.
Den rørformede akseldel har i en vis højde et par diametralt modstående siderettede huller til optagelse af tænderne, og i den nedre kant et par dia-25 metralt modstående hak til optagelse af fremspringene.The tubular shaft portion has at some height a pair of diametrically opposed lateral holes for receiving the teeth, and at the lower edge a pair of diametrically opposed notches for receiving the projections.
Monteringen af halsen gennemføres ved indføring af de elastiske arme i den rørformede akseldel og en derefter følgende orientering af halsen ved hjælp af den sekskantede krave, indtil fremspringene er bragt 30 til flugtning med hakkene. Ved denne orientering trykkes den øvre del af halsen helt ind i den rørformede akseldel. Fremspringene indgriber nu med hakkene, og tænderne snapindgriber i siderne, så at halsen forank res.The neck assembly is accomplished by inserting the resilient arms into the tubular shaft portion and then orienting the neck by the hexagonal collar until the projections are brought into alignment with the notches. At this orientation, the upper portion of the neck is fully pressed into the tubular shaft portion. The protrusions now engage with the notches, and the teeth snap into the sides so that the neck is anchored.
35 Denne kendte løsning har to ulemper. En første ulempe er, at det for at opnå snapsammenkobling er nød- 235 This known solution has two disadvantages. A first disadvantage is that in order to achieve snap interconnection it is necessary 2
DK 159288 BDK 159288 B
vendigt at udføre tre bevægelser, dvs. en aksial bevægelse til indsætning af armene i den rørformede del, derefter en flugtning med de siderettede huller, og endelig en yderligere aksial bevægelse til fuldstændig-5 gørelse af indgrebet.it is necessary to perform three movements, viz. an axial movement for insertion of the arms into the tubular portion, then a flush with the lateral holes, and finally an additional axial movement to complete the engagement.
En anden ulempe er den væsentlige mængde plastmateriale, der behøves til fremstilling af delen. Den øvre, rørformede del må faktisk være temmelig lang for at undgå problemer med tætning af hensyn til olietryk-10 ket, der er maksimalt på niveau med den nedre ende af akslens rørformede del.Another disadvantage is the substantial amount of plastic material needed to manufacture the part. In fact, the upper tubular portion must be quite long to avoid oil pressure sealing problems which are at the maximum at the lower end of the tubular portion of the shaft.
DE-A-15 01 026 angår en elastisk ophængt kompressor til kølemaskiner med en krumtapaksel, hvori en rørformet del ved sin nedre ende bærer en olietrans-15 porthals. Denne olietransporthals kan være fremstillet af et gummielastisk materiale såsom naturligt gummi, kunstgummi eller lignende elastisk materiale. En sådan olietransporthals skydes på den rørformede del af krumtapakslen, som har en rundtgående rille, og fastklemmes 20 ved hjælp af en spændring. Pumpeelementet kan også bestå af metal. I dette tilfælde må pumpeelementet på en eller anden egnet måde være fastklemt på krumtapakslen.DE-A-15 01 026 relates to an elastic suspended compressor for refrigeration machines with a crankshaft, in which a tubular part at its lower end carries an oil transport neck. This oil transport neck may be made of a rubber elastic material such as natural rubber, synthetic rubber or similar elastic material. Such an oil transport neck is slid onto the tubular portion of the crankshaft having a circumferential groove and clamped 20 by a clamping ring. The pump element may also consist of metal. In this case, the pump element must in some suitable way be clamped to the crankshaft.
DE-A-32 19 684 angår ligeledes en olietransporthals, som omkringgribende skydes på den rørformede del 25 af krumtapakslen. Den kan være fremstillet af metal eller plast og er ved hjælp af skruer eller med en prespasning fastgjort på den rørformede del. Den kan også være limet fast. Til øgning af pumpevirkningen er i transporthalsen tilvejebragt en spiralformet, drejet 30 skrueflade, som strækker sig til en ringformet skulder. Transporthalsen hviler med den indvendige ringformede skulder mod krumtapakslen ved den nedre ende af den rørformede del.DE-A-32 19 684 also relates to an oil transport neck which is pivotally slid onto the tubular portion 25 of the crankshaft. It can be made of metal or plastic and is fixed by means of screws or with a press fit on the tubular part. It can also be glued. To increase the pumping effect, a helical, rotated screw surface is provided in the transport neck which extends to an annular shoulder. The transport neck rests with the inner annular shoulder against the crankshaft at the lower end of the tubular member.
US-A-43 75 944 angår en smøreindretning til en 35 motorkompressor. Deri er elementer til transport af smøreolie i olietransporthalsen tilvejebragt i form af ribber eller skovle.US-A-43 75 944 relates to a lubricator for a motor compressor. Therein, elements for transporting lubricating oil in the oil transport neck are provided in the form of ribs or vanes.

Med opfindelsen tilsigtes der tilvejebragt en krumtapaksel af den type, der er omtalt i begyndelsen, og som omfatter et enkelt snapindgreb mellem den rørformede mellemdel og olietransporthalsen uden tæt-5 ningsproblemer.The invention is intended to provide a crankshaft of the type mentioned at the outset which comprises a single snap engagement between the tubular member and the oil transport neck without sealing problems.
Dette opnås ved hjælp af en krumtap som anført i krav 1. Foretrukne udførelsesformer fremgår af underkravene.This is achieved by means of a crank as claimed in claim 1. Preferred embodiments are set forth in the subclaims.
Med opfindelsen tilvejebringes der således en 10 krumtapaksel, der ikke har ulemperne ved kendte konstruktioner, og har en udformning, som gør den enkel og økonomisk at fremstille, og som muliggør en hurtig og effektiv montering.The invention thus provides a crankshaft which does not have the disadvantages of known constructions and has a design which makes it simple and economical to manufacture and which enables quick and efficient mounting.
Opfindelsen beskrives nærmere i det følgende un-15 der henvisning til tegningen, hvor fig. 1 viser et delvis gennemskåret sidebillede af en hermetisk kølekompressor med en krumtapaksel ifølge opfindelsen, fig. 2 et perspektivbillede med delene adskilt 20 fra hinanden af en krumtapaksel ifølge opfindelsen, fig. 3 og 4 to aksialsnitbilleder af den neder-ste del af akslen i fig. 2 vist henholdsvis før og efter samling, og fig. 5 det ene af de i fig. 2-4 viste elementer 25 set ovenfra.The invention is described in more detail below with reference to the drawing, in which: FIG. 1 shows a partially sectioned side view of a hermetic cooling compressor with a crankshaft according to the invention; FIG. Figure 2 is a perspective view with the parts separated 20 from one another by a crankshaft according to the invention; 3 and 4 are two axial sectional views of the lower part of the shaft of FIG. 2 shown before and after assembly respectively, and FIG. 5 shows one of the FIG. 2-4 are top plan views.
Kompressoren 1 omfatter et hermetisk hus 2 af plademateriale, hvori en motor-kompressorenhed 3 er ophængt elastisk.The compressor 1 comprises a hermetic housing 2 of sheet material, in which a motor-compressor unit 3 is elastically suspended.
Et element 4, der fortrinsvis er af støbejern, 30 udgør hovedparten af enheden 3. Elementet 4 kan omfatte en central rørformet del med lodret akse, der tjener som leje for krumtapakslen 5.An element 4, preferably cast iron, constitutes the majority of the unit 3. The element 4 may comprise a central tubular vertical axis portion which serves as a bearing for the crankshaft 5.
Krumtapakslen 5 (fig. 2) omfatter som hoveddele i rækkefølge ovenfra og nedefter en krumtap 6, en 35 excentrik 7 i form af en flad sektor, en rørformet mellemdel 8 og en rørformet hals 9, der divergerer opefter.The crankshaft 5 (Fig. 2) comprises, as main parts, in order from top to bottom a crank 6, a flat eccentric 7 in the form of a flat sector, a tubular middle part 8 and a tubular neck 9 which diverges upwards.

Den øvre del af den rørformede del 8 er lejret i det nævnte leje. Endvidere er undersiden af excentrikken 7 forsynet med en ringformet, fremspringende del 10, der samvirker som et trykleje med en øv-5 re, ringformet fremspringende flade li i lejet.The upper portion of the tubular portion 8 is housed in said bearing. Furthermore, the underside of the eccentric 7 is provided with an annular projecting portion 10 which cooperates as a pressure bearing with an upper annular projecting surface 1i in the bearing.
Rotoren 12 af en elektromotor er på ikke nærmere vist måde fastkilet til den nederste del af den rørformede del 8, idet statoren af denne motor er fastgjort forneden til elementet 4.The rotor 12 of an electric motor is not wedged in a specific manner to the lower part of the tubular part 8, the stator of this motor being fixed below to the element 4.
10 På krumtappen 6 er krumtapenden af en plejl- stang 13 monteret, hvilken plejlstangs anden ende er forbundet med et stempel, der glider i kompressorens cylinder, der er placeret i den øverste del af huset.10 On the crank 6, the crank end of a connecting rod 13 is mounted, the other end of the connecting rod being connected to a piston sliding in the cylinder of the compressor located in the upper part of the housing.
Den nedre del af halsen 9 dykker ned i et smø-15 remiddel 14 i den nederste del af huset 2. Ved rotation af akslen virker halsen 9 på kendt måde som en centrifugal-aksialpumpe, der bringer smøremiddel til at stige op mod excentrikken 7 og krumtappen 6 gennem den rørformede del 8. i den rørformede del 8, i ex-20 centrikken 7 og i krumtappen 6 er der smørehuller, af hvilke nogle er vist i fig. 1 og 2 og er betegnet med 15.The lower part of the neck 9 dives into a lubricant 14 in the lower part of the housing 2. In rotation of the shaft, the neck 9 acts in a known manner as a centrifugal axial pump which causes lubricant to rise against the eccentric 7 and the crank 6 through the tubular portion 8. in the tubular portion 8, the eccentric 7 and in the crank 6 there are lubrication holes, some of which are shown in FIG. 1 and 2 and is designated 15.
Normalt er krumtappen 6 og excentrikken 7 udformet i et enkelt stykke af sintret metal. Den rørfor-25 mede del 8 er imidlertid fremstillet af et rørstykke, der kan være udskåret af et kontinuerligt kalibreret rør af blødt stål af middelkvalitet.Usually, the crank 6 and the eccentric 7 are formed in a single piece of sintered metal. However, the pipe-shaped part 8 is made of a pipe piece which can be cut from a continuously calibrated medium-grade soft steel pipe.
Den rørformede del 8 er forbundet med excentrikken 7 og krumtappen 6 ved indgreb mellem den 30 øvre ende af delen 8 og sædet, der af grænses af den ringformede fremspringende del 10. Når først dette indgreb har fundet sted, tilvejebringes den endelige forbindelse mellem de to dele fortrinsvis ved vortesvejsning. En anden samlemetode består i limning ved 35 hjælp af et metalklæbemiddel.The tubular portion 8 is connected to the eccentric 7 and the crank 6 by engagement between the upper end of the portion 8 and the seat bounded by the annular protruding portion 10. Once this engagement has taken place, the final connection is provided between the two parts preferably by welding. Another method of assembly consists of bonding using a metal adhesive.
Som det bedst ses i fig. 3 og 4 har den rørformede del 8 en ringformet rille 16 ved sin nederste 5As best seen in FIG. 3 and 4, the tubular member 8 has an annular groove 16 at its lower 5
DK 159288 BDK 159288 B
ende. Rillen 16 har en trekantet profil med en nedre keglestubformet side 16a, der konvergerer opefter.end. The groove 16 has a triangular profile with a lower cone stub-shaped side 16a that converges upward.
Halsen 9 omfatter en nedre konisk del 17, der divergerer opefter, og over hvilken der en bøsning 5 18.The neck 9 comprises a lower tapered portion 17 which diverges upwardly, over which there is a bushing 5 18.
I overgangsområdet mellem den koniske del 17 og bøsningen 18 har den indre væg af halsen 9 en ringformet, opadvendende skulder 19.In the transition area between the tapered portion 17 and the bushing 18, the inner wall of the neck 9 has an annular, upwardly facing shoulder 19.
Skulderen 19 har en størrelse svarende til 10 størrelsen af den nederste endeflade 20 af den ringformede del 8.The shoulder 19 has a size equal to 10 the size of the lower end surface 20 of the annular portion 8.
To finner 21 strækker sig aksialt i diametralt modsatte stillinger i den koniske del 17 af halsen 9.Two fins 21 extend axially in diametrically opposite positions in the tapered portion 17 of the neck 9.
15 Finnerne 21 virker på kendt måde som skovle til fremføring af smøremiddel 14 fra bunden af huset 2 ved rotationen af akslen 5.The fins 21 act in a known manner as vanes for advancing lubricant 14 from the bottom of the housing 2 by the rotation of the shaft 5.
Denne fremføringsvirkning, der er tangential i forhold til akslen 5, i forbindelse med den diverge-20 rende udformning af den nedre del 17 af halsen 9, bevirker, at smøremidlet stiger opad i den rørformede del 8. Arrangementet er således, at det maksimale tryk af smøremidlet opnås i overgangsområdet mellem den koniske del 17 og bøsningen 18.This feeding action, which is tangential to the shaft 5, in connection with the divergent configuration of the lower part 17 of the neck 9, causes the lubricant to rise upwards in the tubular part 8. The arrangement is such that the maximum pressure of the lubricant is obtained in the transition region between the tapered portion 17 and the bushing 18.
25 Bøsningen 18 har hakker eller slidser 22, der inddeler den i flere buesegmenter (seks i det viste eksempel), og som forløber lodret fra forbindelsesområdet med den koniske del 17.The sleeve 18 has notches or slots 22 which divide it into several arc segments (six in the example shown) and extending vertically from the connecting region with the tapered portion 17.
Halsen 9 er fremstillet af et enkelt stykke 30 elastisk plastmateriale, som f.eks. polyamid. De buede segmenter af bøsningen 18 er således elastiske og muliggør, at halsen 9 kan monteres på den nederste ende af det rørformede element 8. Flere af bøsningssegmenterne 23 har udvidede hoveder 24 ved 35 deres frie ender, hvilke hoveders inderside hver har et tandformet fremspring 25 med en trekantet profil,The neck 9 is made of a single piece of resilient plastic material, such as e.g. polyamide. The curved segments of the sleeve 18 are thus elastic and allow the neck 9 to be mounted on the lower end of the tubular member 8. Several of the sleeve segments 23 have extended heads 24 at their free ends, the inside of each head having a toothed projection 25 with a triangular profile,
