(54) Motorkompressoraggregat, navnlig til små kølemaskiner·.(54) Motor compressor assembly, in particular for small refrigerators ·.
Opfindelsen angår et motorkompressoraggregat, navnlig til små kølemaskiner, med en krumtapaksel forsynet drivelektromotor, som er anbragt på den ene side af en lejeskjoldagtig lejebærer, på hvis anden side sidder et cylinderhus, og med et af krumtappen drevet stempel, som er bevægeligt ved hjælp af en plejlstang, som, er forbundet med krumtappen ved hjælp af en bøsning, som er indsat i et øje i piejlstangen, hvorhos krumtappen og piejlstangsøjet er således afpasset efter hinanden, at plejlstangen i med stemplet U forbundet stilling kan svinges ind over krumtappen og forbindes q med denne ved indstikning af bøsningen.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a motor compressor assembly, particularly for small refrigeration machines, with a crankshaft drive electric motor disposed on one side of a bearing shield-like bearing, on the other side of which is a cylinder housing, and with a piston driven by crankshaft. a connecting rod which is connected to the crank by means of a bushing inserted into an eye of the bar, the crank and the bar of the eye being so adapted to each other that the connecting bar in position connected with the piston U can be swung over the crank and connected q with this when inserting the bushing.

v) ringen ved, at stemplet med dermed forbundet plejlstang skydes ind i cylinderhuset, hvorefter plejlstangen svinges ud til siden, så *v) the ring by the plunger with associated connecting rod being inserted into the cylinder housing, after which the connecting rod is swung out to the side so that *
"2" at krumtapakslen kan skydes ind i lejebæreren og forbindes med elektromotorens rotor. Derpå drejes stemplet og plejlstangen en vis vinkel omkring cylindrens akse, så at plejlstangen kan svinges med sit øje ind over krumtappen og efter tilbagedrejning omkring cylinderaksen kan forbindes med krumtappen ved indstikning af bøsningen. Til muliggørelse af denne indsvingning af plejlstangen over krumtappen er dens øje i den ene side forsynet med en udsparing, gennem hvilken krumtappen kan passere, og som er således dimensioneret, at piejlstangsøjet efter tilbagedrejning af stemplet og plejlstangen omkring cylinderaksen helt omslutter den ydre ende af krumtappen."2" that the crankshaft can be slid into the bearing carrier and connected to the electric motor rotor. Then the piston and the connecting rod are turned a certain angle around the axis of the cylinder so that the connecting rod can be swiveled with its eye over the crank and after turning around the cylinder axis can be connected to the crank by inserting the bushing. To enable this pivot of the connecting rod over the crank, its eye is provided on one side with a recess through which the crank can pass, which is dimensioned so that, after turning the piston and the connecting rod around the cylinder axis, the pivot rod completely encloses the outer end of the crank. .
Denne monteringsmåde er forholdsvis kompliceret og kræver en særlig formgivning af delene. Opfindelsen har derfor til formål at tilvejebringe et motorkompressoraggregat af den indledningsvis angivne art, som er enklere udformet og lettere at montere.This method of assembly is relatively complicated and requires a special design of the parts. The invention therefore aims to provide a motor compressor assembly of the type specified in the introduction which is simpler in design and easier to assemble.
Ifølge opfindelsen opnås dette ved, at krumtappens længde er således afpasset efter piejlstangsøjets form og dimensioner, at krumtappen i samlet stilling af delene ikke strækker sig med sin ende ind i piejlstangsøjet.According to the invention, this is achieved by the length of the crank being so adapted to the shape and dimensions of the baffle eye that the crank in the overall position of the parts does not extend with its end into the baffle eye.
Ved denne udformning er en frem- og tilbagedrejning af stemplet og plejlstangen omkring cylinderaksen ikke nødvendig ved monteringen af aggregatet, da plejlstangen også uden sådan drejning kan svinges ind over krumtappen til forbindelse med denne ved hjælp af bøsningen. Desuden kan piejlstangsøjet være rotationssymmetrisk udformet og kræver således ingen særlig bearbejdning til fremstilling af en udskæring deri.In this embodiment, a reciprocating rotation of the piston and the connecting rod around the cylinder axis is not necessary in the assembly of the assembly, as the connecting rod can also be swung over the crankshaft for connection with it by means of the bushing without such rotation. In addition, the dipstick eye may be rotationally symmetrically shaped and thus requires no special machining to produce a cut therein.
Opfindelsen er nærmere forklaret i det følgende under henvisning til tegningen, på hvilken fig. 1 viser et hermetisk indkapslet motorkompressoraggregat til en lille kølemaskine, hvis kapsel og lejebærer er delvis bortskåret, og fig. 2 i større målestok et udsnit af fig. 1 til anskueliggørelse af forbindelsen mellem piejlstangsøjet og krumtappen.The invention is further explained in the following with reference to the drawing, in which: FIG. 1 shows a hermetically enclosed motor compressor assembly for a small refrigeration machine, the capsule and bearing carrier being partially cut away; and FIG. 2 is an enlarged sectional view of FIG. 1 to illustrate the connection between the dipstick eye and the crank.
Et i fig. 1 med 10 betegnet motorkompressoraggregat er på kendt måde anbragt i en kapsel 11, som er hermetisk lukket med et dæksel 12. Motorkompressoraggregatet 10 drives af en krumtapaksel 13 i en bag kapslen 11·s væg ikke synlig drivelektromotor. Denne er anbragt på undersiden af en lejeskjoIdagtig lejebærer l4, på hvis anden side sidder et cylinderhus 15. Det ved den ene ende med en ventilplade og et cylinderdæksel 16 lukkede cylinderhus 15 er forenet med den lejaskjoldagtige lejebærer 14 til en i ét stykkeOne in FIG. 1, designated by 10, the motor compressor assembly is arranged in a known manner in a capsule 11 which is hermetically sealed with a cover 12. The motor compressor assembly 10 is driven by a crankshaft 13 in a drive electric motor not visible behind the capsule 11. This is arranged on the underside of a bearing sheath bearing 14, on the other side of which is a cylinder housing 15. At one end, a cylinder housing 15 closed at one end with a valve plate and a cylinder cover 16 is connected to the bearing shield bearing 14 in one piece.
