Definitions

  • the invention relates to a rolling bearing of a water pump of an internal combustion engine, with rolling bodies consisting of balls and rollers according to the preamble of patent claim 1.
  • raceways for rolling body rings are incorporated at a certain distance.
  • a ball race and a roller ring form a double-row fixed bearing floating bearing arrangement.
  • the roller ring is located as a floating bearing on the side of the water pump shaft loaded by the Riemenyak a drive pulley higher, while the ball race is usually designed as a fixed bearing and absorbs the radial thrust and the axial thrust of the impeller.
  • the invention has for its object to provide a rolling bearing of a water pump of an internal combustion engine, which consists of balls and rollers Wälzkör- pern, which avoids the disadvantages of the prior art and in particular has a compact design, and is able to safely absorb the axial and radial forces occurring ,
  • the invention is based on the finding that the stated object can be achieved in a surprisingly simple manner in that the rolling bearing of the water pump shaft is designed as a single-row roller ball bearings.
  • the invention is therefore based on a rolling bearing of a water pump of an internal combustion engine, consisting of balls and rollers rolling elements, which are arranged between a bearing outer ring and a shaft of the water pump, wherein the radially inner periphery of the bearing outer ring and extending within the bearing outer ring portion of the radially outer Periphery of the shaft has a ball track, in which the balls are arranged in rolling contact with the ball track.
  • the rolling bearing is designed as a single-row roller ball bearings.
  • the rolling bearing is designed to be very compact, that is to say narrow, while being able to securely absorb the axial and radial forces which occur. Due to the construction with a small axial width not only less space can be used, it can also be saved significantly weight, since the bearing outer ring is correspondingly lightweight due to the short length.
  • Roller ball bearings so single-row bearings, where alternately roles and balls are arranged between a bearing inner ring and a bearing outer ring, are known per se, for example by CH 241 985 B, DE 1 898 225 U1 and DE 41 42 433 C1.
  • the balls which also serve to absorb the axial forces, are arranged in grooves or Kugel Insertsbah- NEN, while the rollers that serve to absorb the radial forces roll on the remaining shoulder surfaces of the bearing rings.
  • roller ball bearings for storage of water pump waves is not possible, since such an arrangement in addition to the bearing outer ring also makes a bearing inner ring necessary.
  • bearing inner rings are not considered for water pump waves, as this would lead to unacceptable leakage problems and to further stress at least of radial space.
  • the invention combines the advantages of the previously known bearings for waves of water pumps in that the rollers, which can absorb radial forces particularly well, and the balls, which are particularly well suited for receiving axial forces, in an axial plane of the Rolling be arranged, in such a way as it is known from roller bearings.
  • rollers are arranged between shoulders of the bearing outer ring and the radially outer periphery of the shaft, the shoulders axially limiting the ball guide track of the bearing outer ring.
  • the balls and rollers are held in a common cage.
  • This embodiment can be supplemented by the fact that the cage is a cage closed on both sides or on one side.
  • Other practical embodiments of the invention are characterized in that the rollers and balls are arranged uniformly alternately in the rolling bearing.
  • rollers and balls are arranged unevenly alternately in the rolling bearing, wherein between a sequence of rollers whose number is 2 to 4, a ball is arranged.
  • the bearing outer ring is formed without a bord, or, alternatively, that the bearing outer ring has at least one board, which limits the rollers axially.
  • the rollers are cylindrical rollers or spherical rollers.
  • an embodiment of the invention is particularly advantageous, which is characterized in that between the axial ends of the bearing outer ring and the shaft seals are arranged.
  • FIGURE shows a sectional view through an embodiment of a rolling bearing on a water pump shaft according to the invention.

  • the shaft 2 has a first free end portion 3 and a second free end portion 4, wherein the first end portion 3 has a larger diameter than the second end portion 4.
  • the provided with the larger diameter first end portion 3 is driven, in particular by means of a belt drive, not shown in the drawing of the internal combustion engine.
  • the provided with the smaller diameter second end portion 4 is rotatably coupled to the drive of the water pump.
  • an intermediate region 5 is provided which has the same diameter as the drive-side first end section 3.
  • the intermediate region 5 of the shaft 2 is surrounded by an outer bearing outer ring 6.
  • the radially inner periphery 7 of the bearing outer ring 6 and the radially outer periphery 8 of the intermediate region 5 are each provided with opposing ball guideways 9 and 10, in which rolling elements in the form of balls 1 1 are mounted rolling, of which in the drawing only a ball 1 1 is shown.
  • the ball guide track 9 of the bearing outer ring 6 is bounded by axial shoulders 12 and 13, which define radially together with the periphery 8 of the shaft 2 rollers 14 in the form of cylindrical rollers.
