Definitions

  • the present invention relates to a refrigerant compressor comprising an electric drive unit, a cylinder housing, a crankshaft driven by the electric drive unit, and a crankshaft driven in the
  • the present invention further relates to a family of refrigerant compressors of different refrigerating capacity, each refrigerant compressor comprising an electric drive unit, a cylinder housing, a crankshaft driven by the electric drive unit, and a cylinder-driven, refrigerant-compressing piston driven by the crankshaft the electric drive unit of each refrigerant compressor of the family depending on the cooling capacity has a different height.
  • Such refrigerant compressors are well known and are mainly used in the household sector, such as refrigerators or freezers. They are arranged in a hermetically sealed outer housing and part of a refrigerant circuit in which the refrigerant compressor compresses a gaseous refrigerant which is supplied from an evaporator of the piston / cylinder unit. When compressing the refrigerant pressure and temperature increase. As a result, the refrigerant is transferred in a condenser in the liquid state and finally fed through an expansion valve to the evaporator, where it evaporates again. The necessary heat of vaporization is removed from the environment or a cold room, which is thereby cooled. Finally, the gaseous refrigerant from the evaporator is returned to the piston / cylinder unit and undergoes a new compression and expansion cycle.
  • refrigerant compressors with different cooling capacities are offered.
  • the component which essentially determines the cooling capacity of a refrigerant compressor is the electric drive used.
  • the displacement and thus the piston size vary as well as the hub itself and thus contribute to different cooling capacities.
  • the overall height of a refrigerant compressor is essentially determined by the height of the electric drive unit and the height of the mounted on the electric drive unit cylinder housing. While the overall height of the cylinder housing is kept constant in general and only the cylinder diameter and the cylinder stroke varies slightly depending on the cooling capacity, the height of the electric drive unit varies significantly depending on the cooling capacity.
  • the electric drive unit is usually a single-phase asynchronous motor, which consists of a rotor and a stator together with winding packages, wherein the stator is formed as a laminated core, which significantly affects the height of the electric drive unit, as will be explained in more detail below .
  • the refrigerant compressor itself is arranged in a hermetically sealed outer housing, into which a suction line opens, which leads the refrigerant to the cylinder, and from which a pressure line leads away, which conducts the compressed refrigerant to the condenser. Furthermore, there is a connection flange for electrical lines on the hermetically sealed housing to supply the drive unit with electricity inside.
  • an oil sump for lubricating the moving parts of the refrigerant compressor.
  • the oil is conveyed to the lubrication points due to the rotation of the crankshaft itself, which for this purpose has two sections provided with different oil conveying means (oil delivery spindle, eccentric bore).
  • compressor family Several refrigerant compressors with a large number of identical components are referred to as the compressor family.
  • the individual members of a compressor family differ from each other by the cooling capacity and / or by the efficiency and thus mainly by the electric drive unit used.
  • Outer housing, crankshaft, cylinder housing, etc. are therefore identical or nearly identical (exceptions: cylinder bore diameter, stroke, and various mounting exemptions), to allow economic production.
  • the height compensation elements In addition to maintaining the overall height of the refrigerant compressors within a family of compressors, however, the height compensation elements also allow to always use identical crankshafts for each member of a compressor family by keeping the cylinder housing, which has the main bearing for the crankshaft always equidistant from the bottom of the outer casing , regardless of the height of the between cylinder housing and bottom of the outer housing arranged electric drive unit. Thus, the same length crankshafts can always be used. Without the height compensation, shorter crankshafts would have to be used due to the smaller distance between the cylinder housing and the bottom of the outer housing in refrigerant compressors with smaller electric drive units.
  • the main bearing in particular the lower main bearing has to be sufficiently high inside the housing for housing the larger electric drive unit, between main bearings of the crankshaft and oil sump.
  • the located below the lower main bearing portion of the crankshaft must therefore have sufficient length to still be able to immerse in the oil sump at the bottom of the outer housing in order to promote the oil to the lubrication points.
  • a refrigerant compressor with an electric drive unit, a cylinder housing, driven by the electric drive unit crankshaft and driven by the crankshaft, guided in the cylinder housing, the refrigerant-compressing piston that between the cylinder housing and the electric drive unit at least one height compensation element is arranged.
  • the cylinder housing has at least one contact flange, which is fastened to at least one corresponding contact surface of the electric drive unit, wherein the at least one height compensation element is arranged between the contact flange and the contact surface.
  • the electric drive unit is a single-phase synchronous motor and in the contact area around the laminated core of the stator of the single-phase synchronous motor.
  • each refrigerant compressor of the compressor family in a compressor family, each refrigerant compressor of the compressor family, an electric drive unit, a cylinder housing, driven by the electric drive unit crankshaft and driven by the crankshaft , guided in the cylinder housing, the refrigerant-compressing piston comprises and wherein the electric drive unit of each refrigerant compressor of the compressor family depending on the cooling capacity and efficiency from the height of the electric drive unit and from the height of the cylinder housing (without height compensation elements) composed different height, is provided that at least one height compensation element angeor between the electric drive unit and the cylinder housing of each refrigerant compressor dnet is.
  • the distance between the lower edge of the height defining portion of the electric drive and the axis of the cylinder housing in each compressor can be set substantially identical and the overall height can be kept constant and it is possible to grow the electric drive unit up toward the cylinder housing and at the same time the main camp as deep as possible in the vicinity to arrange the oil sump.
  • the dimensioning of the main bearing length can then take place in this case due to the largest electric drive unit and so the bearing load and friction losses are minimized within a compressor family.
  • the section defining the overall height of the electric drive is the height of the laminated core of the stator.

  • the outer housing in Fig.l was not drawn.
  • the cylinder housing 1 has a plurality of contact flanges 5, which extend in the direction of the crankshaft axis 6 and stand up on the Bleckbeck 2. Cylinder housing 1 and laminated core 2 are not fixed to each other in Fig.l screws connected to each other, which penetrate from below the laminated core 2 and end present in the Aufstandflanschen 5, having a threaded holes.
  • FIG. 2 shows a sectional view of a refrigerant compressor according to Fig.l including the outer housing 10, which is composed of two hermetically sealed housing halves 10a, 10b. 2 also shows the crankshaft 11 which drives the piston 12 via a connecting rod 13.
  • the crankshaft 11 is mounted in a section of the cylinder housing 1 designated as the main bearing 14 and is preferably fastened to a rotor 15 of the electric drive unit by means of a press fit.
  • FIG. 2 shows a connection flange 16 fastened to the outer housing 10 for electrical lines, a suction muffler 17 arranged on the cylinder head and support feet 19, which serve for fixing the outer housing 10 to an external contact area.
  • FIG. 3 shows a sectional view of a prior art refrigerant compressor with the upper half of the outer case 10a omitted. Well visible now are the holes 7 in the laminated core 2 and in the risers 5, and the screws extending therein, which serve to connect the laminated core 2 and the cylinder housing 1.
  • the overall height Hi of the refrigerant compressor is composed of the height H z i of the cylinder housing 1, which extends from the lowermost end of the contact flanges 5 to the piston axis 24, and the height of the electric drive unit, which is determined by the height H. e i of the laminated core 2, which is why subsequently laminated core and electric drive unit are used synonymously.
  • the outer housing 10 is matched to the refrigerant compressor such that the upper housing half 10a runs just above the cylinder housing 1 and runs down in the region of the electrical connection flange 16 in the direction of the same.
  • the outer housing of a compressor family is always dimensioned after that refrigerant compressor with the greatest power.
  • height compensation elements are provided, for example in the form of support elements 8 and 9, which are surrounded by a spiral spring element 4, which are arranged below the electric drive unit 2, for example, on the underside of the laminated core 2 and on which the refrigerant compressor superimposed.
  • the height of a height compensation element is thus composed of the total height of the support elements 8, 9, including the surrounding spiral spring element 4, which is set under load by the refrigerant compressor.
  • FIG. 4 shows a refrigerant compressor of the same type as in the prior art but with a lower cooling capacity. This is recognizable on the one hand at the lower height H e2 of the laminated core 2 and the lower due to the different bore diameter height H z2 of the cylinder housing 1 and thus a lower overall height H 2 .
  • height compensation elements constructed of the support elements 8,9 and the spiral spring elements 4, of the same type as described in Fig. 3, are provided, but with the difference that they have a greater height H h2 than the height H h i of the height compensation elements forming components 4, 8, 9 in Figure 3.
  • FIG. 5 shows a purely schematic view of a prior art refrigerant compressor according to FIG. 3 with the largest electric drive unit 2 of a compressor family and FIG. 6 with the smallest electric drive unit 2 of the same compressor family.
  • main bearing length H L and bearing width B L are identical in both cases, so that the larger electric drive unit 2 of Figure 5 reduces the distance between the compressor and the oil sump 19, since the total height H Ges of the refrigerant compressor so limited by the height of the outer housing is.
  • the main bearing length H L of this compressor could be increased and thus the bearing load can be reduced or retained the bearing load but the friction losses can be reduced.
  • the press fit length P L of the attachment of the rotor 15 to the crankshaft 11 would then be smaller in this case, but would still be sufficiently dimensioned or in other words the press fit length P L in Figure 5 is unnecessarily large and it would be advantageous the main bearing length H. L to increase the bearing forces and to achieve smaller friction losses. If, however, the main bearing length H L were to be increased, the required smallest possible interference fit length P L min could not be maintained for smaller compressors of the same compressor family as shown in FIG.
  • the oil head H oe i (without immersion depth E t ) to the lower main bearing 18 is therefore unnecessarily high in known refrigerant compressors to provide space for the largest electric drive unit 2 a compressor family, although, as shown in Figure 6, the lower main bearing 18th could be arranged closer towards oil sump 19.
