Description
Technical Field
The utility model belongs to the technical field of the bearing design, mainly relate to a high-speed biserial bearing ring connection structure.
Background
Compared with a single-row bearing, the double-row bearing has the characteristic of large bearing capacity and is widely applied. In order to be convenient to process and assemble, the inner ring (or the outer ring) of some double-row bearings is formed by combining two single-raceway inner rings (or outer rings), some double-row bearings are directly formed by combining two sets of single-row bearings, and at the moment, the bearings are separable. If the separable ring does not take any connecting measures, the bearing has the risk of loose sleeve in the processes of transportation and installation.
Separable type bearing often adopts the mode of tying up to connect in the transportation, can only solve the transportation and loose the cover problem, but the bearing still is the separated type when actual installation, and the installation of being not convenient for is used. Although some connecting structures for tightly clamping the bearing on the outer surface or the inner diameter surface are reliable, the tightly clamping parts radially exceed the outer diameter surface or the inner diameter surface of the bearing, so that the tightly clamping parts need to be removed when the bearing is installed, and the assembly efficiency is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the background art, the utility model aims to provide a high-speed double-row bearing ring connecting structure.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a high-speed double-row bearing ring connecting structure comprises an outer sleeve and an inner sleeve, wherein the outer sleeve is used for connecting two outer rings; the outer diameter surfaces of the two outer rings are provided with notches I, and the notches I on the two outer rings are butted to form an annular notch; the outer sleeve is positioned in the annular notch groove, and gaps are formed between the outer sleeve and two side wall surfaces of the annular notch groove; the outer sleeve is in interference fit with the bottom surface of the annular notch, and the outer diameter of the outer sleeve is smaller than that of the outer ring;
the inner diameter surfaces of the two inner rings are provided with notches II, and the notches II on the two inner rings are butted to form an annular notch; the inner sleeve is positioned in the annular notch groove, and gaps are formed between the inner sleeve and two side wall surfaces of the annular notch groove; the inner sleeve is in interference fit with the bottom surface of the annular notch, and the inner diameter of the inner sleeve is larger than that of the inner ring.
The outer sleeve is used simultaneously with the inner sleeve.
The outer sleeve and the inner sleeve are alternatively used.
The utility model provides a high-speed biserial bearing ring connection structure, adopt above-mentioned technical scheme, compare with bundling type connection, the sleeve connection structure is more reliable, and bearing inner circle, outer lane all realize the installation of counterpointing completely; compare with the connected mode of lock ring in bearing (outer) surface, embedded in bearing ring's telescopic connection structure need not to get rid of connecting sleeve, can directly install, and the bearing installation of being convenient for has improved efficiency.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. inner circle, 2, outer lane, 3, scarce groove I, 4, scarce groove II, 5, outer sleeve, 6, inner skleeve.
Detailed Description
The present invention will be described with reference to the accompanying drawings.
As shown in fig. 1, a high-speed double-row bearing ring connecting structure has an outer sleeve 5 for connecting two outer rings 2 and an inner sleeve 6 for connecting two inner rings 1; the outer diameter surfaces of the two outer rings 2 are also cylindrical, the outer diameter sizes are the same, the connecting end is provided with a notch I3, the width and the diameter of the notch I3 are the same, and the notches I3 on the two outer rings are butted to form an annular notch; the outer sleeve 5 is positioned in the annular notch, and gaps are formed between the outer sleeve 5 and two side wall surfaces of the annular notch; the outer sleeve 5 is in interference fit with the bottom surface of the annular notch, and the outer diameter of the outer sleeve 5 is smaller than that of the outer ring 2;
the inner diameter surfaces of the two inner rings are cylindrical surfaces, the inner diameters are the same in size, the connecting end is provided with a radial notch II 4, the width and the diameter of the notch II 4 are the same, and the notches II 4 on the two inner rings are butted to form an annular notch; the inner sleeve 6 is positioned in the annular notch, and gaps are formed between the inner sleeve 6 and two side wall surfaces of the annular notch; the inner sleeve 6 is in interference fit with the bottom surface of the annular notch, and the inner diameter of the inner sleeve is larger than that of the inner ring.
The outer sleeve is used simultaneously with the inner sleeve.
The outer sleeve and the inner sleeve are alternatively used.
The inner sleeve and the outer sleeve are both made of engineering plastics.
The outer sleeve 4 connects the two outer rings of the bearing into a whole through the axial friction force and the radial supporting action of interference fit. In the embodiment, if the bearing outer ring is integral, only the inner sleeve 6 is required to be connected with the two inner rings of the bearing; if the inner ring of the bearing is integral, only the outer sleeve 4 is needed to be connected with the two outer rings of the bearing; for the bearing with only the separable outer ring and the integral inner ring, an inner sleeve is not needed, and only the outer sleeve described in the technical scheme is needed for connection. For the bearing with only the separable inner ring and the integral outer ring, an outer sleeve is not needed, and only the inner sleeve described in the technical scheme is needed for connection.
