Opfindelsen angår en motorkompressor af den i krav l's indledning nævnte art. Ved de kendte motorkompressorer er krum-taparmen i ét stykke, hvilket har den ulempe, at indbygningen af krumtapdrevet bliver vanskeliggjort, og at tilretning af ~ 5 plejløjerne bliver ret kompliceret. Det samme gælder en kendt krumtapkonstruktion, der er opbygget af skiveformede elementer, der er sammenføjet i planer vinkelret på aksen.The invention relates to a motor compressor of the kind mentioned in the preamble of claim 1. In the known motor compressors, the crank arm is one-piece, which has the disadvantage that the incorporation of the crank drive becomes difficult and that the alignment of the ~ 5 groove eyes becomes quite complicated. The same applies to a known crank structure, which is made up of disc shaped elements joined together in planes perpendicular to the axis.

Motorkompressoren ifølge opfindelsen, som den er karakteriseret i krav 1, har i forhold til det kendte den fordel, 10 at den delte krumtaparm gør monteringen af krumtapdrevet ganske enkel og uden vanskelighed muliggør tilretning af stempel-øjerne. Desuden kan det skadelige rum indstilles, og den nedre del af krumtaparmen samt drivakselen kan være ens for forskellige byggestørrelser af kompressoren.The motor compressor according to the invention, as characterized in claim 1, has the advantage of the prior art that the shared crank arm makes the assembly of the crank drive quite simple and without difficulty enables alignment of the piston eyes. In addition, the damaging space can be adjusted and the lower crank arm as well as the drive shaft may be the same for different build sizes of the compressor.

15 Ved de i underkravene angivne foranstaltninger er fordelagtige udførelsesformer og forbedringer mulige.15 By the measures specified in the subclaims, advantageous embodiments and improvements are possible.

Særlig fordelagtigt er det at udforme motorakselen som et rør, med hvilket den ene del (den nedre) af krumtaparmen er fast forbundet.It is particularly advantageous to design the motor shaft as a pipe with which one part (the lower) of the crank arm is firmly connected.

20 På tegningen er der vist en udførelsesform for kom pressoren ifølge opfindelsen, som vil blive forklaret nærmere i det følgende.In the drawing there is shown an embodiment of the compressor according to the invention, which will be explained in more detail below.

Fig. 1 viser et længdesnit gennem motorkompressoren, fig. 2 et snit langs linien II-II i fig. 1, 25 fig. 3 i snit en ændret del af den i fig. 1 viste udførelsesform, og fig. 4 det samme som fig. 3, men set fra oven.FIG. 1 is a longitudinal section through the motor compressor; FIG. 2 is a section along line II-II of FIG. 1, FIG. 3 is a sectional view of an altered portion of FIG. 1, and FIG. 4 the same as FIG. 3, but seen from above.

Motorkompressoren er indlagt i en kapsel 10, der består af en underdel 11 og en overdel 12, som er hermetisk tæt 30 sammensvejset. I kapslen er der anbragt en elektromotor 13, hvis stator 14 ved hjælp af fjedre 15 er understøttet på en grundplade 16, der er anbragt i kapslens underdel. Fjedrene 15 ligger på den ene side an mod udboringsagtige udsparinger 17 på statoren 14 mod en deri anbragt konisk tap 18, på den oc '· anden side mod en tilsvarende konisk tap 19, der er fastgjort på grundpladen 16. Elektromotoren 13's rotor 19 er anbragt på en rørformet aksel 20, der er styret og lejret i et hovedleje 2 145243 o 4 21.The motor compressor is housed in a capsule 10 which consists of a lower part 11 and a upper part 12 which are hermetically tightly welded together. An electric motor 13 is provided in the capsule, the stator 14 of which is supported by springs 15 on a base plate 16 arranged in the lower part of the capsule. The springs 15 abut one side against bore-like recesses 17 on the stator 14 against a tapered pin 18 disposed thereon, and on the other side against a corresponding tapered pin 19 attached to the base plate 16. The rotor 19 of the electric motor 13 is arranged. on a tubular shaft 20 guided and mounted in a main bearing 2.

Hovedlejet 21 er en del af et lejeorgan 22, der er f relativt smalt og broagtigt udformet, og som støtter mod sta-toren 14 med to støtteføddep 24 og 25, der ligger diametralt 5 over for hinanden. Det er fastgjort til denne ved hjælp af skruer 26 og 27. Lejeorganet 22 spænder kun over den øvre del af viklingen 28 i elektromotoren på et smalt område på grund af dens ringe bredde, så at denne del af viklingen bliver godt afkølet.The main bearing 21 is part of a bearing member 22 which is relatively narrow and bridged, and which supports against the stator 14 with two support foot pads 24 and 25 which are diametrically 5 opposite each other. It is attached thereto by screws 26 and 27. The bearing member 22 only spans the upper part of the winding 28 of the electric motor on a narrow area due to its small width, so that this part of the winding is well cooled.

10 På lejeorganet 22 befinder stempelkompressoren 31's cylinder 30 sig. X cylinderen 30 er der udformet en gennemgående cylinderudboring 32, hvis akse står vinkelret på motorakselen 20. I udboringen 32 kan et stempel 33, der er tætsluttende til cylindervæggen, glide. Stemplet er på kendt 15 måde ved hjælp af en stempelkile 34 forbundet med en plejl-stang 35, hvis øje 36 sidder på krumtappens søle 37.10 On the bearing member 22, the cylinder 30 of the piston compressor 31 is located. X cylinder 30 is provided with a through-hole bore 32, the axis of which is perpendicular to the motor shaft 20. In bore 32, a piston 33 which is tightly adjacent to the cylinder wall can slide. In a known manner, the plunger is connected by means of a plunger wedge 34 to a connecting rod 35, the eye 36 of which rests on the column 37 of the crank.

Krumtaparmen 38 er udformet med henblik på stempeldrevets vægtudligning. Den består af to skiveformede dele 38' og 38", hvis ydre mål er nøjagtigt lige store. Den neder-20 ste del 38" har en udboring 39, hvormed den er sat ned omkring den øvre del af akselen 20 og fast forbundet til denne, f.eks. ved svejsning eller lodning. Efter monteringen af krumtapdrevet bliver den øvre del 38' af krumtaparmen anbragt ud for den nederste del 38" af krumtaparmen og efter indstilling 25 fast forbundet med delen 38". Dette kan hensigtsmæssigt ske ved svejsning eller lodning eller ved en skrueforbindelse 40 som vist i fig. 3. I stedet for skrueforbindelsen 40 kan der også bruges andre fastgørelsesmidler, f.eks. nitning. Det er også muligt at benytte en sammenlimning af delene 38' og 38!" · 30 Krumtapsølen 37 er fast forbundet til overdelen 38' af krumtaparmen 38. Den er på formålstjenlig vis anbragt i en udboring 41.The crank arm 38 is designed for the weight compensation of the piston drive. It consists of two disc-shaped portions 38 'and 38 ", the outer dimensions of which are exactly the same. , eg. by welding or soldering. After mounting the crank drive, the upper portion 38 'of the crank arm is disposed adjacent to the lower portion 38 "of the crank arm and, after adjustment 25, is firmly connected to the portion 38". This may conveniently be done by welding or soldering or by screw connection 40 as shown in FIG. 3. Instead of the screw connection 40, other fasteners, e.g. riveting. It is also possible to use a bonding of the parts 38 'and 38! "

Ved passende indstilling af delene 38' og 38" af krumtaparmen 38 kan stempelkompressoren 31's skadelige rum indstil-35 les. Akselen 20 og underdelen 38" kan være ens til forskellige kompressorstørrelser (byggekasseprincip), og kun overdelen 38' bliver varieret.By appropriately adjusting the parts 38 'and 38 "of the crank arm 38, the damper space of the piston compressor 31 can be adjusted. The shaft 20 and the bottom 38" can be the same for different compressor sizes (building box principle) and only the upper 38' is varied.

Lejeorganet 22 kan lægges langs med den viste X-akse, eller langs den på X-aksen vinkelrette Y-akse.The bearing member 22 may be laid along the X-axis shown, or along the Y-axis perpendicular to the X-axis.
