Plain bearing

专利摘要:
To improve a sliding element, in particular a sliding bearing, with an inhomogeneous antifriction layer, consisting of a support layer (32) and a sliding bearing material layer (27) applied to the support layer and provided with groove-like recesses arranged at a distance from one another and extending at least over part of the sliding surface and filled with another sliding bearing material (30) (filler material), optimal dimensioning of the groove-like recesses (26), specific to the relevant bearing loading is achieved in respect of width, depth and distance, taking into account the relevant sliding material of the bearing and the material in the groove-like recesses (filler material).

专利说明:

The invention relates to mechanical engineering, in particular to sliding bearings.
The purpose of the invention is to increase the service life by increasing the limit of fatigue and wear resistance.
FIG. 1 shows a sliding bearing formed from two halves; in fig. 2 is a plain bearing in the form of a support sleeve; in fig. 3 - half of one-piece bearing with collar: in FIG. 4 - half of the bearing and two half-ring thrust washers; in fig. 5 - execution of groove-like depressions with a width of b 0.3s, b 0.23a, b 1.6t; in fig. 6 - the same, with a width of b - 1 s, b - 0.5 a, b 4t; in fig. 7 - the same, with a width of b 3s, b 0.75 a, b - 10t;
in fig. 8 - the same, with a width of b 10s, b 0.91a, b 25t.
FIG. Figures 1 and 2 show the sliding bearing 1 in the form of two halves 2 and 3 or in the form of a support sleeve 4, which can be made without a seam or bent and with an axial spline 5.
The sliding bearing 1 has a supporting layer 6 of steel and a supporting layer 7 based on a metal alloy deposited on it, and the groove-like depressions 8, filled with a metal alloy that may differ from the supporting alloy, are installed on the surface of the supporting layer. Between the hollow grooves 8 are made jumpers 9.
The groove-like recesses 8 can be made in a variety of ways. So,

for example, circular grooves or screw grooves with a small angle of elevation (up to 15 °) can be used. Position 10 marked the central axis of the bearing. With this ratio of the width b of the groove-like depressions to the width s, the remaining between the recesses of the jumpers, the distance a between the centers of two adjacent jumpers and their depth t is such that b (0.3-1) 8, b (0.23-0 , 5) a, b (1.6-4) t for the base layer with a loadability of 10-30 N / mm2 with a filler with a loadability of 40-100 N / mm2 in the slots; b (1-3) s, b (0.5-0.75) a and b (4-10) t for the base layer with a loading capacity of 30-50 N / mm2 with a filler with a loading capacity of 20-40 N / mm2 in the slots; b (3-10) s, b (0.75-0.91) a and b (10-25) t for the base layer with a loading capacity of 50-140 N / mm with a filler with a loading capacity of 50-20 N / mm2 in the slots.
Between the carrier layer 7 and the material filling the groove-like depressions 8 there can be a diffusion barrier or connecting layer with a thickness of 0.5-6 microns.
Half of the sliding bearing 3 (FIG. 3) is provided with a first flange 11 and a second flange 12, and the flange 11 is also provided in the base layer with grooves-like depressions 8, made spirally or concentrically to the central axis of the bearing. The second shoulder can be made the same as first, or in the usual way, i.e. with a smooth surface carrier layer. - To form a full sliding bearing, half 3 is connected to the second half (not shown), which can be performed as half 3, or in the usual way.
Such sliding bearings can also be made, which have collars 11 and 12 in the form of divided thrust washers mounted on the radial part of the bearing through connecting plates.
Depending on the choice of material for
the carrier layer and the filling of the groove-like grooves of the latter, as a rule, have a width of 40-250 µm and a depth of 10-25 µm, with the width between the groove-like grooves of the remaining bridges being 25-120 µm.
Thus, an increase in the service life of the sliding bearing is achieved.
by increasing the fatigue and wear limit.
