Definitions
- the invention relates to a method for producing a bearing ring for slewing bearings with at least one raceway with hardened surface layer, in which the surface layer to be hardened is exposed to the electric field of an inductor for heating and then quenched.
- bearing rings are screwed via axially introduced passage and / or threaded holes with the connection structures.
- Large-diameter bearings can, depending on the design, have one or more rows of balls or rollers.
- Each ball or roller series includes two raceways, which are machined in two to three bearing rings and then hardened.
- Such bearing rings may be formed as nose rings, support rings, retaining rings, disc-shaped axial rings, outer rings or inner rings, etc.
- the raceways of the bearing rings of large rolling bearings are hardened by a known method with one or two inductors in the feed.
- a so-called inductor i. an induction coil or an induction coil pair and for quenching a shower mounted on the inductor for the task of cooling liquid arranged over a small relative to the ring diameter zone of the raceway to be cured.
- the inductor and shower once stroke the contour of the raceway of the entire ring in the circumferential direction with constant advance of the ring, so that continuously heated and quenched each segment of the track.
- the invention is based on the object to provide a method for producing bearing rings for slewing bearings, with the circumferentially constant in the raceways, i. slip-free high hardness can be adjusted.
- a) at least two inductors are arranged at the beginning of the curing over a common zone (a) of the annular track to be hardened and there heat the opposite edge layer to hardening temperature, b) for heating the subsequent central zones (b) the inductors in the opposite direction along the annular runway are moved, c) after a short distance on the heated edge layers directed showers turned on and they are quenched from the center of the initially heated zone (a), d) the inductors and the showers on their ring halves to be moved until they at at a point opposite the starting point E) after reaching the required hardening temperature of the zone (c) both inductors are lifted vertically from the surface of the track and f) the showers are directed to the zone (c).
- inductors in each case at least two inductors, preferably two induction coils or two pairs of induction coils and, preferably, nozzles attached thereto, are arranged above a zone of the track to be hardened which is small in relation to the ring diameter.
- both inductors are arranged directly next to one another and uniformly heat the underlying raceway layer to hardening temperature (see Item 1 in the appended Figures 1 and 3).
- the formation of a common heating zone constant depth can be achieved by a pendulum movement of the inductors or the ring and an adapted power control.
- both inductors move in each opposite circumferential direction along the annular surface layer to be hardened of the track with constant feed apart.
- the showers preferably pivotally mounted to the inductors, are turned on, scare off the center of the initially heated zone, and divide the zone heated to hardening temperature into two halves.
- Each inductor then sweeps at constant feed the raceway surface of one half of the circumference of the ring in the opposite direction (Pos. II) until both coincide again at a position opposite the starting track section and form a common heating zone (Pos. III).
- a simultaneous preheating of the region opposite the starting point by a third inductor can be provided (see Fig. 2).
- the third inductor is removed as soon as the two remaining inductors approach the hardening of this zone and analogously to pos. III of FIG.
- both inductors form a common heating zone.
- both inductors move vertically away from the surface.
- the common heating zone is quenched simultaneously.
- FIG. 1 and 2 are perspective views of a bearing ring with different inductor positions I to IV
- Fig. 3 shows a schematic cross-section of the inductors 2 and showers 5 in the different inductor positions I to IV
- Fig. 4a is a circle segment of the track 3 with the representation of the common heating zones a, c and
- Fig. 4b shows a modified embodiment of Fig. 4a with introduced at the edges of the track 3 holes or grooves 6, leading to the illustrated enlargement of the common heating zones a, c.
- the bearing ring 1 shows the bearing ring 1 with the axial track 3 to be hardened and the inductors 2 in the different inductor positions I to IV.
- the zone a shown in dashed lines is heated.
- the two inductors 2 then move along the annular track 3 in the direction of the arrow via the position II with the associated mean heating zones b up to the position III with the local heating zone c.
- the inductors 2 are raised in the axial direction from the position III to the position IV, so that the pivotable to the inductors 2 paved showers can also deter the boundary layer in the area of zone c.
- the inductors 2 and showers 5 in the four different inductor positions I to IV are shown schematically.
- the showers 5 are arranged above the respective inductors 2.
- the spray jets are shown in dashed lines and directed to the edge layer of the raceway, which has just been heated by means of the inductors 2.
- the inductors 2 are still arranged directly next to one another and the showers 5 are switched off.
- the inductors 2 have a short distance away from the O ° line and the effervescent jets are directed obliquely backwards to the track.
- the inductors 2 have been brought together again to 180 ° -ünie.
- the nozzles 5 pivotally mounted on the inductors are pivoted so that the effervescent jets are initially directed perpendicular to the edge layer and later possibly even to the surface under the inductors 2.
- the inductor 4 for preheating is additionally shown, which is removed from this area as soon as the other two inductors 2 approach this area.
- FIGS. 4a and 4b how the common heating zones a, c are enlarged when suitable bores or grooves 6 are made at the edges of the track 3.
- inductors induction coils or induction coil pairs
