Specific embodiment
Specific embodiments of the present invention are further elaborated below.It should be understood that herein to the present invention
The explanation of embodiment is not intended to limit the scope of protection of the present invention.
It as shown in Figure 1 to Figure 3, is the structural schematic diagram of three column combination bearing provided by the invention.A kind of three column
Combination bearing includes an outer ring 10, and a cylindrical bearing group 20 being arranged in the outer ring 10 and two are respectively set
In the conical bearing group 30 of the axial sides of the cylindrical bearing group 20.It is envisioned that the three column combination bearing also wraps
Other some functional units are included, such as seal assembly, lubricating oil etc., which is a technique known to those skilled in the art, In
This is no longer described in detail one by one.
The roller container 11 that the outer ring 10 is integrally formed and is arranged on inner sidewall including one, two are respectively set
Circular cone roller surface 12 in roller container two sides, and the positioned trenches 13 in the outside of the outer ring 10 are set.In
Along the axial section of the outer ring 10, the roller container 11 include one section of cylindrical raceway face 111 and one section with should
The rib 112 that cylindrical raceway face 11 connects.The cylindrical raceway face 111 with the cylindrical bearing group 20 for matching.Two
The circular cone roller surface 12 is for matching setting with two conical bearing groups 30 respectively.In order to make the conical bearing group
30 tapered settings, on the axial section along the outer ring 10, the contour line of the circular cone roller surface 12 and the outer ring
Angle between 10 axial direction includes an obtuse angle.The positioned trenches 13 when installing the three column combination bearing for positioning
The relative position of the three column combination bearing and mounted position such as axis.
The cylindrical bearing group 20 includes a cylinder inner ring 21 and multiple settings in the cylinder inner ring 21 and cylinder
Cylindrical roller 22 between roller surface 111.The cylindrical raceway face 111 is along the axial length of the outer ring 10 and the cylinder
The axial length of roller 22 is suitable, so that the cylindrical roller 22 is folded in the cylindrical raceway face 111, but described in order to make
Cylindrical roller 22 smoothly rolls, the cylindrical raceway face 111 and 22 clearance fit of cylindrical roller, while the cylindrical raceway
Face 111 is less than the radius of the cylindrical roller 22 along the radial length of the outer ring 10, to reduce friction.In addition, by institute
It states cylindrical bearing group 20 and does not have traditional roller cage, any two in the multiple cylindrical roller 22, which contact with each other, to be set
It sets.On the axial section along outer ring 10, axial length of the rib 112 along the outer ring 10 is greater than cylindrical roller 22
Axial length.In the radial direction along the outer ring 20, the maximum in the outside of the cylinder inner ring 21 to the cylindrical raceway face 111
Distance is suitable with the diameter of the cylindrical roller 22, and the cylindrical roller 22 is folded in the cylinder inner ring 21 and is rolled with cylinder
Between road face 111.On the axial section along the cylindrical roller 22, the cross sectional shape of the cylindrical roller 22 can be square
Shape.On the axial section along the outer ring 10, the axial length of the cylinder inner ring 21 is most greatly enhanced with the rib 112
Degree quite, is interfered to avoid cylindrical roller 22 and conical bearing group 30.
The conical bearing group 30 includes a cone 31, and multiple settings are in the cone 31 and circular cone raceway
Taper roller 32 and a setting between face 12 is between the cone 31 and circular cone roller surface 12 and for positioning
The retainer 33 of the taper roller 32.The conical bearing group 30 as common structure, be the prior art, herein no longer
It is described in detail.The cone 31 is suitable with the internal diameter of the cylinder inner ring 21, and the cylinder inner ring 21 is folded in two
Between the cone 31.Angle between the central axis of the taper roller 32 and the central axis of the cylindrical roller 22 is
One obtuse angle, so that axial direction tapered setting of the taper roller 31 relative to the outer ring 10.
Compared with prior art, three column combination bearings of the invention use three column Combined roller design schemes, bearing two
The combination that son is taper roller 32 and centre uses cylindrical roller 22 is sidewindered, it is excellent in conjunction with taper roller 32 and cylindrical roller 22
Point, left and right double-row conical 32 can guarantee that bearing has the two-way carrying stress performance of good axial direction, intermediate cylindrical roller 22
The radial carrying stress performance of bearing is then effectively improved, impact resistance load-bearing capacity is strong.The three-row bearing is same compared to other
Class bearing promotes axially compressed behavior 125% with can effectively promote diameter stress performance 125% under identical size.
