Definitions

• the invention relates to an axial roller bearing according to the preamble of forming features of claim 1, and it is particularly advantageous for one-sided wir-kenden axial deep groove ball bearings applicable, as used for example for storing the rotor shaft in compressors for household refrigerators. Background of the invention
• Such reciprocating compressors consist essentially of a hermetically sealed housing in which a cylinder block is resiliently mounted, which receives the stator of an electric motor consisting of a coil package.
• the arranged inside the stator and formed with permanent magnets rotor of the electric motor is mounted on a centric rotor shaft which is guided through the cylinder block and at its end a wave washer having an eccentrically mounted crank pin.
• the connecting rod eye of a connecting rod is placed, which is connected to a piston disposed in a compressor unit reciprocating, so that the rotational movement of the rotor shaft is converted into a translational movement of the reciprocating piston.
• the compressor unit is arranged on the cylinder block and has a hollow cylinder connected to a suction line and a pressure line in which the reciprocating piston reciprocates to alternately increase and decrease a pressure chamber located in front of the reciprocating piston.
• Such an axial grooved ball bearing is known, for example, from DE 20 2006 016 321 U1 or US Pat. No. 7,168,859 B2 and has a first cylinder-head-side annular bearing disk, to which a second disk-side annular bearing disk is arranged at a distance from a common center axis.
• the bearing discs are formed on their inside disc surfaces with mutually facing groove-shaped raceways in which a plurality arranged in a row and by a bearing cage at regular intervals to each other rolling elements roll.
• This Axial- Rillenkugella-ger is due to the design of the assembly of the reciprocating compressor in the unassembled state, ie separated in pulleys and in the bearing cage pre-assembled ball set, and is completed only during assembly of the reciprocating compressor.
• the invention is therefore the object of an axial roller bearing, in particular unidirectional axial deep groove ball bearings to design, with the unintentional incorrect assembly of the bearing discs in the assembly of the items of the axial deep groove ball bearing Safety are avoidable.
• this object is achieved in an axial roller bearing according to the O-berbegriff of claim 1 such that both bearing discs are formed on their outside disc surfaces with other, to the raceways on their inside disc surfaces in position, diameter and groove depth identi-see groove-shaped raceways which the bearing disks can be mounted independently of a specific installation assignment either as a first or as a second bearing disc at an intended bearing point and in each possible mounting position to each other the necessary number of mutually facing raceways for the rolling elements aufwei- sen.
• the invention is not based on the obvious obvious knowledge that it is possible by arranging further, for the actual bearing function in itself meaningless care on the backs of the bearing discs in a simple and cost-effective manner, unintentional incorrect assembly of the bearing discs during assembly to exclude the individual parts of the axial deep groove ball bearing with certainty.
• the inventively designed Axial anymorelzlager that it is formed as a single-row axial deep groove ball bearing whose bearing discs each have a groove-shaped track on their inside disc surfaces and on their outside disc surfaces also each have a groove-shaped track.
• a design according to the invention on two or more row axial ball bearings or also on single or multi-row axial taper roller or axial spherical roller bearings.
• the axial rolling bearing designed in accordance with the invention is characterized by the fact that both bearing disks have the same internal and external diameters and material thicknesses and are each made without cutting by stamping from a steel sheet with subsequent heat treatment without further post-processing.
• An axial rolling bearing designed and manufactured in this way has proven to be particularly advantageous, in particular with regard to its low production costs, since the uniform design of the bearing disks and the choice of material are only possible low tool and material costs caused.
• the drawing clearly shows a single-row axial deep groove ball bearing designed axial roller bearing 1, which has a first annular bearing disk 2 and a spaced therefrom on a common central axis 3 second annular bearing disk 4.
• the bearing discs 2, 4 are formed on their inside disc surfaces 6, 7 with two mutually facing groove-shaped raceways 10, 1 1, in which a plurality arranged in a row and by a bearing cage 13 at regular intervals held rolling elements 14 roll.
• both bearing disks 2, 4 on their outside disk surfaces 5, 8 with further, identical to the raceways 10, 1 1 on their inside disk surfaces 6, 7 in position, diameter and groove depth groove-shaped raceways 9, 12th are formed, through which the bearing plates 2, 4 regardless of a specific installation assignment either as first or second bearing disc 2 or 4 are mounted on a designated bearing point and in each possible mounting position to each other the necessary number facing each other tracks 10, 1 1 for the Have rolling elements 14.
• Both bearing disks 2, 4 have the same inside and outside diameters as well as equal material thicknesses and are in each case manufactured without cutting by punch embossing from a steel sheet with subsequent heat treatment without further post-processing.
• the after mounting the bearing discs 2, 4 to the Outside disk surfaces 5, 8 of the bearing discs 2, 4 arranged raceways 5, 8 have no meaning in storage operation.
