Can prevent impurity from entering in view of this, the present invention provides one kind can prevent outflow of lubrication oil again The package assembly of three column combination bearings, to solve the above technical problems.

A kind of package assembly of three column combination bearing, it is characterised in that：The three column combination bearing includes a cylindrical shaft Hold group, the conical bearing group of two axial sides for being separately positioned on the cylindrical bearing group, one is arranged in the cylindrical shaft Hold the outside of group and conical bearing group outer ring and two clip assemblies for being respectively used to be clamped the conical bearing group, institute Stating conical bearing group includes a cone bearing inner ring, and the cone bearing inner ring and the outer ring interval are arranged, the clip assembly It is arranged between the outer ring and cone bearing inner ring, the clip assembly is folded in described including a becket and one Elastic component between becket and cone bearing inner ring, the becket have L-shaped structure, and a line of the becket is folded in Between the elastic component and the inner wall of outer ring.

Further, the elastic component is made of fluorubber.

Further, on the radial section along the becket, the elastic component includes an interconnecting piece, and one sets It sets and is connected to the support portion of the interconnecting piece other side the top of the interconnecting piece side and one.

Further, the interconnecting piece is annular in shape.

Further, on the radial section along the becket, the top is black triangle, the triangle The right-angle side of shape is supported on the becket.

Further, the support portion be include that the head connecting with the interconnecting piece and one connect with the head Labyrinth type structure.

Further, an annular groove is offered on the head.

Further, the labyrinth type structure is eight word portions

Further, eight word portion is supported on the cone bearing inner ring of the conical bearing.

Compared with prior art, this implements clip assembly possessed by the package assembly of three novel column combination bearings by bullet Property part and becket form, elastic component completes by squeezing becket the assembling of the conical bearing group because of elastic deformation, and Fastening of the entire clip assembly in outer ring is completed by recovery deformation, the impurity in external environment is effectively prevent to enter bearing and axis The loss of internal lubrication rouge is held, so as to improve the service life of the three column combination bearing.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the package assembly of three column combination bearing provided by the utility model.

Fig. 2 is the partial enlargement diagram at A of the package assembly of the three column combination bearings of Fig. 1.

Specific embodiment

Specific embodiment of the utility model is further elaborated below.It should be understood that herein to this The explanation of utility model embodiment is not used to limit the protection scope of the utility model.

It as shown in Figure 1 to Figure 2, is the structural representation of the package assembly of three column combination bearing provided by the utility model Figure.The package assembly of the three column combination bearing includes a cylindrical bearing group 10, and two are separately positioned on the cylindrical bearing The conical bearing group 11 of the axial sides of group 10, outside that the cylindrical bearing group 10 and conical bearing group 11 be set Outer ring 12 and two are respectively used to the clip assembly 13 being clamped between the conical bearing group 11 and outer ring 12.

Axially a setting ring 121 is extended in direction for the outer ring 12, so as in the freedom of the outer ring 12 End slot milling is for installing the clip assembly 13.

The cylindrical bearing group 10 includes a column bearing inner race 101 and multiple settings in the column bearing inner race 101 Cylindrical roller 102 between outer ring 12.

The conical bearing group 11 includes a cone bearing inner ring 111, and multiple settings are in the cone bearing inner ring 111 and outside Taper roller 112 between circle 12 and one are for fixing the roller ring 113 of the taper roller 112.The conical bearing Group 11 should be the known techniques of those skilled in the art, is no longer described in detail herein.In order to which the clip assembly 13, institute is arranged State cone bearing inner ring 111 and the setting of the outer ring 12 interval and including a setting table 114.The setting table 114 and the outer ring 12 setting ring 121 is oppositely arranged.

The clip assembly 13 is arranged between the outer ring 12 and cone bearing inner ring 111, specifically, the clip assembly 13 It is arranged between setting ring 121 and the setting table 114 of cone bearing inner ring 111 of the outer ring 12.The clip assembly 13 includes One becket 131 and an elastic component 132 being folded between the becket 131 and cone bearing inner ring 111.It is described Becket 131 has a L-shaped structure, a line of the becket 131 be folded in the elastic component 132 and outer ring 12 inner wall it Between.The elastic component 132 is made of fluorubber.On the radial section along the becket 131, the elastic component 132 is wrapped An interconnecting piece 133 is included, a top 134 that 133 side of interconnecting piece is arranged in and one are connected to the connection The support portion 135 of 133 other side of portion.The interconnecting piece 133 is annular in shape.On the radial section along the becket 131, institute Stating top 134 is black triangle, and the right side of the triangle is supported on the becket 131.The support portion 135 Including the head 137 being connect with the interconnecting piece 133 and a labyrinth type structure 138 being connect with the head 137.It is described Labyrinth type structure 138 is eight word portions.Further, an annular groove 139 is offered on the head 137.Eight word portion branch Support is on the cone bearing inner ring 111 of the conical bearing 11.

Compared with prior art, this implement clip assembly 13 possessed by the package assembly of three novel column combination bearings by Elastic component 132 and becket 131 form, and elastic component 132 is because elastic deformation is by squeezing the completion cone axis to becket 131 The assembling of group 11 is held, and fastening of the entire clip assembly 13 in outer ring 12 is completed by recovery deformation, effectively prevent external environment In impurity enter bearing and Bearing inner lubricating grease and be lost, so as to improve the service life of the three column combination bearing.
