Definitions
- the invention relates to a slide bearing for a shaft of an exhaust gas turbocharger of an internal combustion engine, in particular a motor vehicle, with a cylindrical bearing bushing which has an axial bearing bore for receiving the shaft of the exhaust gas turbocharger, wherein in the bearing bore at the axial ends of the cylindrical bearing bushing a first slide bearing surface for each radial bearing of the shaft of the exhaust gas turbocharger is formed, a second slide bearing surface is formed on each axial end face of the cylindrical bearing bush for an axial bearing of the shaft of the exhaust gas turbocharger, and the bearing bore is formed in an axial section between the first slide bearing surfaces such that a gap between a wall of the bearing bore and the shaft of the exhaust gas turbocharger is formed according to the preamble of claim 1.
- WO 99/07982 discloses a combined axial / radial bearing in the form of a one-piece bearing bush for both axial and radial mounting of a shaft of an exhaust gas turbocharger.
- lubricating oil is introduced with respect to the bearing bush in the middle under pressure into a bearing bore in which the shaft of the exhaust gas turbocharger rotates.
- Axial grooves are formed along a central bore of the bearing bush which receives the shaft, in order to transport the lubricant away from the central introduction and in the axial direction to end faces of the bearing bush. These are connected to V-shaped radial grooves on the end faces of the bearing bush.
- the invention has for its object to improve a slide bearing of the type mentioned above with respect to the bearing and the bearing play.
- a lubricant feed in the form of an annular groove is formed in the area of each of the first slide bearing surfaces on the outer circumference of the cylindrical bearing bush, with first bores are arranged and designed such that they produce a lubricant-conducting connection between the annular groove and the respective first sliding bearing surface and second bores are arranged and designed such that they produce a lubricant-conducting connection between the annular groove and the respective second sliding bearing surface.
- first bores and / or second bores are evenly spaced apart from one another in the circumferential direction and twice as many second bores are formed as the first bores.
- At least one of the second bores is assigned a groove on the second sliding surface and this groove is designed in such a way that it produces a lubricant-conducting connection between the second bore and the bearing bore.
- the first bores are formed in the radial direction and the second bores in the axial direction, the second bores being designed to be tilted parallel to the bearing bore or at a predetermined angle thereto.
- 1 shows a preferred embodiment of a bushing of a plain bearing designed according to the invention in a schematic sectional view
- 2 is a plan view of an end face of the bearing bush according to FIG. 1
- FIG. 4 shows a plan view of an end face of the bearing bush according to FIG. 3,
- FIG. 5 shows a section along the line V - V according to FIG. 4,
- Fig. 6 is a section along the line VI - VI of Figure 4.
- FIG. 7 shows a perspective view of the bearing bush according to FIG. 3.
- FIG. 1 schematically shows part of a shaft 10 of an exhaust gas turbocharger, which is otherwise not shown in detail.
- a turbine wheel 12 is rotatably connected to this shaft 10.
- a compressor wheel (not shown) is connected to the shaft 10 on a side of the shaft 10 opposite the turbine wheel 12, so that the shaft 10 establishes a rotationally fixed connection between the compressor wheel and the turbine wheel 12.
- the shaft 10 is supported in a slide bearing 14 between the compressor wheel and the turbine wheel 12.
- This slide bearing 14 has a cylindrical body in the form of a bearing bush 16.
- the bearing bush 16 is provided with an axial bearing bore 18 which receives the shaft 10.
- the bearing bore 18 has a larger diameter in an axial central section 20, so that the shaft 10 is supported radially only at axial ends of the bearing bush 16 within respective first slide bearing surfaces 22.
- Second slide bearing surfaces 24 are formed on the respective end faces of the bearing bush 16. By abutting these second slide bearing surfaces 24 on a shaft collar 26 of the shaft 10 on the one hand and an axial disk 28 arranged on the shaft 10 on the other hand, the shaft 10 is axially supported.
- the bearing bush is provided on its outer circumference with an annular groove 30, which serves as a feed for a lubricant or lubricant, such as, for example, lubricating oil.
- first bores 32 are formed, which extend essentially in the radial direction and produce a lubricant-conducting connection between the annular groove 30 and the respective first slide bearing surface 22.
- second bores 34 are formed, which extend essentially in the axial direction or slightly tilted to a longitudinal axis 36 of the bearing bore 18 and a lubricant-conducting connection between the Create the annular groove 30 and the respective second slide bearing surface 24.
- a plurality of first and second bores 32, 34 are provided in each case, which bores are evenly spaced in the circumferential direction.
- the second bores 34 open on the respective second slide bearing surface 24 for the axial mounting of the shaft 10.
- Grooves 38 are formed on the second slide bearing surface 24 of each end face of the bearing bush 16, with every second bore 34 having a groove 38 assigned.
- Each groove 38 is designed and arranged such that it creates a lubricant-conducting connection between the second bore 34 and the bearing bore 18. In this way, additional lubricant is supplied to the axial ends of the axial bearing of the shaft 10 in the first slide bearing surfaces 32.
- FIG. 3 shows a side view of a slightly modified bearing bushing 16.
- the second bores 34 run axially parallel to the longitudinal axis 36 of the bearing bore 18. These second bores 34 in turn extend from the second slide bearing surfaces 24 into the area of the annular groove 30 and run out in this.
- FIG. 4 illustrates the arrangement of a total of eight grooves 38 in this slightly modified bearing bush 16, with a second bore 34 being assigned to every second groove 38.
- the flat grooves 38 are here also open to the bearing bore 18, while they are delimited on their radially outer region by sections 40 of the second slide bearing surface 24.
- the number of holes 32 and 34, their exact alignment and diameter are determined by the need for lubricant, depending on the application.
