Definitions

  • the invention relates to a reciprocating engine, in the form of an air conditioning compressor for motor vehicles, comprising a housing, with a rotatably driven shaft, with a Wellenabdichtvoriques, in particular a mechanical seal, with at least one radial shaft bearing, in particular a radial rolling bearing, with at least one axial shaft bearing, in particular an axial roller bearing , Wherein in the housing within an opening projecting into the housing bearing sleeve is arranged, which receives at least the radial shaft bearing.
  • Such reciprocating engines are known, such as from DE-A-102 03 073 ,
  • the bearing sleeve and the housing is connected to each other for example by a weld, wherein the weld is arranged in a region with high alternating loads and in case of failure of the weld there is the possibility that solve parts of the housing.
  • a reciprocating engine such as air conditioning compressor for motor vehicles, with a housing, with a rotatably driven shaft, with a Wellenabdichtvorraum, in particular a mechanical seal, with at least one radial shaft bearing, in particular a radial rolling bearing, with at least one axial shaft bearing, in particular an axial roller bearing wherein in the housing within a opening projecting into the housing bearing sleeve is arranged, which receives at least the radial shaft bearing, wherein the bearing sleeve has a first collar, seen in the axial direction, housing side from the inside to the outside, within the housing on an annular Support surface in a recess within the housing comes to rest, so that on the bearing sleeve, seen from the housing side, from the outside to the outside acting axial forces positively received by the housing (introduced into the housing) can be.
  • a reciprocating piston engine in which the first bearing collar a second, smaller-diameter collar, seen from the housing side, from the inside to the outside, axially upstream, which engages through an opening of the housing. Furthermore, a reciprocating engine is preferred in which the first collar with the second collar represents a common stepped collar, which passes through the opening of the housing in a form-fitting manner in the radial and axial directions.
  • a reciprocating piston engine according to the invention is characterized in that the radial outer region of the second collar with the radial inner region of the opening of the housing represents a common area for introducing a weld seam.
  • This has the advantage that the weld is in the range of low stress in terms of axial forces of the axial shaft bearing, since the axial forces can be introduced through the first collar in the housing. Even with a failure of the weld, the bearing sleeve would be held by the axial forces positively within the housing.
  • a reciprocating engine is preferred in which the bearing sleeve receives the axial shaft bearing on an axial end face within the housing. Furthermore, a reciprocating engine is preferred in which the bearing sleeve receives the radial shaft bearing within a radial recess. Also, a reciprocating engine is preferred in which the bearing sleeve receives within a further radial recess a mechanical seal.
  • a further reciprocating piston engine according to the invention is characterized in that the bearing sleeve between the areas in which the mechanical seal and the radial shaft bearing are arranged, has lubricant openings for the mechanical seal and the radial shaft bearing. Also, a reciprocating engine is preferred in which the bearing sleeve radially outwardly within the housing has a groove which serves as a lubricant collecting groove and contains the lubricant openings.
  • Another reciprocating piston engine according to the invention is characterized in that the bearing sleeve outside the housing has a region for receiving a rolling bearing of a pulley.
  • a bearing sleeve 5 is inserted in an opening 3.
  • the opening 3 has a smaller diameter part 7 and a larger diameter part 9, so that the opening 3 is practically represented as a stepped annular opening.
  • the bearing sleeve 5 engages with a smaller diameter collar 13 and a larger diameter collar 15, so that there is an axial bearing surface 17 between the bearing sleeve 5 and the housing part 1.
  • FIG. 2 is a cross section through the corresponding part of the air compressor with the housing part 1 and the bearing sleeve 5 is shown.
  • the bearing sleeve 5 is penetrated by a drive shaft 23, which is mounted with an axial shaft bearing 25 on an axial end surface 27 of the bearing sleeve 5. Furthermore, in the region 29 of the bearing sleeve 5, the shaft 23 with a mounted radial roller bearing 31.
  • a mechanical seal with a fixed part 35 and a rotating part 37 is arranged in a front region 33 of the bearing sleeve 5.
  • lubricant passage openings 39 are arranged inside the sleeve, which open outwardly from the interior of the sleeve 5 in a circumferential groove 41 around the sleeve 5.
  • the groove 41 serves in the drive chamber of the compressor as Schmierstoffauffangnut and passes through the openings 39, the lubricant in the region of the bearing sleeve between the mechanical seal 35/37 and the radial roller bearing 31.
  • a rolling bearing 45 is arranged, which supports the pulley 47.
  • both the bearing surfaces for the radial roller bearing 31 and the radial roller bearing 45 can be produced in a voltage and thus a tolerance-favorable machining can be realized. It is ensured by the division of the compressor housing into a large housing part 1 and a smaller bearing sleeve part 5, that for machining the bearing seats, a small component can be used, which is easier to clamp and edit than a large one-piece housing, which otherwise this corresponding Bearing seats would have to.
  • FIG. 3a is the bearing sleeve 5 and the complete housing component 1 separately and in FIG. 3b shown in the assembled state.
  • the corresponding weld is applied, preferably in this area a laser welding is to be made on a very narrow area with a large depth, as in the cross section of FIG. 1 can be produced in the area 21 can be produced.
  • the inventive solution of the corresponding design of the bearing sleeve 5 and the housing part 1 thus lead by the better machinability of the sleeve 5 to a cost reduction and by the corresponding positioning of the step collars and the weld to an increase in component safety. Even with a failure of the weld is ensured by the positive connection between the sleeve 5 and the housing 1 in the direction of the axial forces 19 a secure, positive connection.
