Definitions
- the present invention relates to a rolling bearing unit with rolling elements arranged between two annular axial bearing disks, which are guided by means of a bearing cage formed from a sheet metal material according to claim 1 .
- DE 103 13 183 A1 discloses an axial roller bearing unit of the type of interest here.
- a collar is arranged on an outer peripheral edge of a thrust bearing disk, which is extended by a flange.
- a radially inwardly directed nose-like projection is formed, which engages radially from behind the cage on the outside circumference.
- the other axial bearing disk is designed as an angle disk and engages behind the bearing cage on the inside with an axial leg. This angular geometry of the thrust bearing washers creates a self-contained thrust roller bearing unit.
- the invention includes the technical teaching that in an axial roller bearing unit with roller bearings arranged between two annular axial bearing disks, which are guided by means of a bearing cage formed from a sheet metal material, which has an inner and outer radial edge rim extending in the axial direction for radial guidance of the roller bodies, at least one of the edge rims is designed as a double rim with a bend at the end in the opposite direction, with its distal end section being designed for positively locking the first axial bearing disk and an edge rim of the bearing cage opposite the double rim being designed for positively locking the second axial bearing disk, in order overall to form a self-retaining structural unit to accomplish.
- the edge rim designed as a double rim is arranged radially inside and the other edge rim is arranged radially outside the bearing cage. This allows precise movement play in the radial direction of up to 0.1 mm compared to a shaft or the like carrying the axial roller bearing unit, since a double rim can be formed more precisely and with more dimensional stability than a simple bend in a leading axial bearing component.
- the other edge rim of the bearing cage is also provided with a distal end section for positively locking the second axial bearing disk.
- both distal end sections of the rims preferably have a rim that at least partially surrounds the assigned axial bearing disk.
- the two axial bearing washers are advantageously designed as identical parts and can therefore be used universally. In addition to reducing the manufacturing complexity, the number of individual parts required is reduced in particular.
- the axial roller bearing unit according to the invention consists of only three different types of individual components.
- a manufacturing advantage in the axial roller bearing unit according to the invention results from the fact that not only the bearing cage is made from a formed sheet metal material, but preferably also the annular axial bearing disks, which can be formed as stamped and embossed parts.
- the edge bevel or the edge shoulder of the axial bearing washers can be manufactured in a simple manner by embossing.
- FIG. 1 shows a perspective sectional view of an axial roller bearing unit according to the invention in a first embodiment
- FIG. 2 shows a perspective sectional view of an axial roller bearing unit according to the invention in a second embodiment.
- an axial rolling bearing unit consists of two identical annular axial bearing disks 1 and 2, between which rolling elements 4 guided via a bearing cage 3 are arranged (as an example).
- the bearing cage 3 is formed from a sheet metal material and has an inner radial edge 5 extending in the axial direction and an outer radial edge 6 also extending in the axial direction.
- the rolling bodies 4 designed as rollers or needles are guided radially between the two edge rims 5 and 6 .
- Both distal end sections 8 and 10 have an edge rim 9 or 11, respectively, which at least partially encompasses the associated axial bearing disks 1 or 2.
- the two edges 9 and 11 are designed as caulking in this embodiment, of which - not shown here - more rere caulking are distributed along the respective circumference to enclose the associated axial bearing washers 1 and 2 in a form-fitting manner.
- the form-fitting edging takes place in such a way that the at least partially bent rim 9 and 10 comes to rest on the axial bearing disks 1 and 2, depending on the inner and outer radially introduced edge bevels 12 and 13, respectively.
- the edge bevels are formed here at an angle of 45° to the longitudinal axis of the bearing. A correspondingly relatively small, partially bent rim 9 or 11 is sufficient for this.
- the axial bearing disks 1' and 2' have an inner and outer radial edge step 12' and 13', which in principle forms a 90° gradation of the edge area.
- An assigned stretched distal end section 8' and 10' of the assigned edge rims 5' and 6' which is thinner than the edge rim thickness, comes into contact with it in such a way that the border does not protrude beyond the outer side surface of the axial bearing washer 1' and 2'.
- the entire rim 9 and 10 should each be bent over by 90°.
