Definitions

  • the invention relates to an oil slinger for a transmission shaft, which is attached to the transmission shaft in the circumferential direction and in the radial direction and has a plunging part arranged in the region of the outer circumference.
  • centrifugal disc for lubricants is already known from EP 0 224 740 AI.
  • the centrifugal disc is arranged in a side space of an piston vacuum pump filled with oil on a rotor shaft.
  • the centrifugal disc has a radially inwardly open circumferential groove with several spray openings.
  • the invention is based on the object of designing and arranging an oil slinger in such a way that use in a limited installation space is ensured.
  • the object is achieved in that the immersion part at least partially has at least one edge region on the outer circumference with at least a thickness d that is smaller than the thickness D of the oil slinger. It is thus achieved that the oil spinner disc absorbs lubricant in a very narrow space with the narrower immersion part and delivers it to deposits arranged radially to the oil spinner disc.
  • the edge region and / or the immersion part it is advantageous for the edge region and / or the immersion part to have a shape which tapers in cross section in the radial direction. The transition between the oil slinger and the narrower immersion part can also take place continuously, so that the lubricant absorbed in the lubricant sump is not exposed to any break-off edge during the radial flow process.
  • an additional possibility is that the edge area is aligned with a first side or a second side with respect to the axial expansion of the oil slinger disc or is arranged offset from the outside inwards between the two sides.
  • the oil slinger is only tapered on one side or on both sides in the area of the immersion part, so that there are corresponding effects on the effective level or spray plane of the oil slinger.
  • the immersion part distributed over the circumference has at least one recess arranged in the edge region, the radial extent T of which corresponds approximately to the radial extent of the immersion part and the axial extent of which is at least 5% of the thickness D of the oil slinger.
  • the axial extent T of the recess must be at least so large that a corresponding lubricant film can set up as it travels through the lubricant sump, which is not prematurely stripped or hindered due to the narrow installation space conditions in the area of further transmission members lying on one side of the oil slinger disc.
  • this is axial expansion according to the amount of lubricant to be pumped.
  • the recess is arranged on the first and / or second side and the recess is arranged offset on the first and on the second side and with respect to the circumferential direction.
  • the staggered arrangement of the recesses distributed over the circumference ensures a sufficient and an almost constant flow of lubricant.
  • the number of recesses on both sides varies between 3 and 300, depending on the size of the recess, the size of the oil slinger and the lubricant flow to be pumped.
  • the immersion part has at least one nose protruding radially outwards with respect to the circumferential circle.
  • the nose protruding outwards guarantees a common collection and detachment point for the lubricant over the circumference of the oil slinger.
  • the formation of the nose shape enables the lubricant to be removed precisely.
  • the oil slinger has a continuous circumferential line in the area of the nose, so that the flow of the lubricant is guaranteed.
  • the immersion part and / or the nose is assigned at least one guide groove arranged on at least one side for use with lubricant.
  • the Guide grooves ensure additional lubrication of the immersion part.
  • the guide grooves can have a wide variety of widths or depths or also cross-sectional shapes, so that, depending on the viscosity or the speeds used, an optimal lubricant wetting of the oil slinger and thus an adequate lubricant flow is ensured.
  • At least two guide grooves have a common exit point, the exit point optionally being arranged at the radially outer end of the nose.
  • the immersion part has a rough, structured surface that supports the thickness of the lubricant film.
  • the guide groove is oriented in the radial direction, in the circumferential direction and / or the contour of the circumferential circle.
  • the shape and the orientation of the guide grooves favor the wetting process by the lubricant on the one hand and the flow process on the other hand by the immersion part of the lubricant centrifugal disc up to an exit point or a tear-off edge of the lubricant.
  • Fig. 1 shows a side view of an oil slinger
  • Fig.lb is a sectional view of the oil slinger
  • Fig. 2 shows a side view of an oil slinger
  • Fig. 3 is a sectional view of a transmission
  • the oil slinger 1 according to FIG. 1 has a circular basic shape, to which a multiform recess 7 is assigned on the inside.
  • the circular disk-shaped oil slinger 1 thus formed has an immersion part 1.3 on the outer circumference.
  • the recess 1.4 has an extension in the radial direction which corresponds approximately to that of the circular ring surface or the immersion part 1.3.
  • the recess 1.4 has a rectangular cross section with respect to a central or longitudinal axis 2.2, the aspect ratio of height to width being approximately 2: 1. According to FIG.
  • the oil slinger 1 is essentially rectangular in cross section with respect to the circumferential direction.
  • an edge region 1.8 is provided, the thickness d of which is approximately 40% of the thickness D of the oil slinger and which has an extension corresponding to the oil slinger in the radial direction.
  • the edge region 1.8 is also rectangular in cross section with respect to the circumferential direction.
  • the rectangular recess 1.4 according to FIG. 1 has a depth T which is approximately 30% of the thickness D of the oil slinger 1.
  • Each side 1.1, 1.2 of the oil slinger 1 has seven recesses evenly distributed over the circumference, the recesses 1.4 of the first side 1.1 being offset from the recesses 1.4 'of the second side 1.2.
  • the oil slinger 1 has a plurality of guide grooves 1.6, 1.6 'on the outer circumference in the area of the immersion part 1.3.
  • the guide grooves 1.6 run circumferentially in this case, that is to say aligned with the outer circumference, all guide grooves 1.6, 1.6 'having a plurality of common exit points 1.7, 1.7'.
  • the guide groove 1.6 which is in itself aligned with the outer circumference, leads radially outward, so that lubricant guided therein, due to the existing centrifugal forces, throws off radially outward at this exit point 1.7.
  • the exit point 1.7 is optionally arranged in the region of a bulge or nose 1.5 of the circumference.
  • Both the guide grooves 1.6 as well as the recesses 1.4 and the edge region 1.8 represent lubricant receptacles to which oil or lubricant adheres when passing through the lubricant sump according to FIG. 3 and which is sprayed radially outwards by the rotation of the oil slinger 1.
  • the part of a transmission shown in FIG. 3 has a housing wall 5 in which a first transmission shaft 2 is rotatably mounted via a roller bearing 2.1 and a second transmission shaft 3 via a roller bearing 3.1.
  • the first gear shaft 2 is in operative connection with the second gear shaft 3 via a gear 4.1.
  • the gear 4.1 is in this case rotatably mounted on the second gear shaft 3 and is brought into engagement with further gear members via coupling means, not shown.
  • a further gear 4.2 is also rotatably arranged, which is not in direct engagement with the first gear shaft 2.
  • the first gear 4.1 and the second gear 4.2 are spaced apart by a spacer 4.3.
  • the oil slinger 1 is arranged on the first shaft 2 in a rotationally fixed manner.
  • the oil slinger 1 is in this case with its inner multi-tooth profile according to Figure 1 with the tooth flanks 2.3 of the first shaft 2 in engagement.
  • a lubricant sump 8 is provided in the lower part of the transmission, which has a fill level 6.
  • the oil slinger 1 with its deepest part is located directly in the lubricant sump 8 and is wetted there with lubricant.
  • the lubricant adheres in the area of this immersion part 1.3, that is to say at the edge area 1.8 within the recesses 1.4 and within the guide grooves 1.6.
  • the radially acting acceleration forces the lubricant during the turning process of the oil slinger, which takes place synchronously with the first shaft 2, upwards according to FIG. 3 to the spacer 4.3 or the bearing arrangement of the first gear .1 and the second gear 4.2.
