Description
Technical field
The utility model belongs to bearing mnanufacture technical field, especially has radiator structure with one kind applied to agricultural machinery
Agricultural machinery hub bearing it is relevant.
Background technology
Agricultural machinery hub bearing is mainly used on agricultural machinery, with the characteristics of rotating speed is low and load is big, because single makes
Longer with the time, hub bearing inner heat is higher, if Bearing inner temperature is more than 120 °, bearing easily fails, and passes
The agricultural machinery hub bearing of system easily makes in bearing as shown in figure 1, the external diameter area of dissipation of its outer ring 1 is smaller in use
Portion's heating is severe and causes bearing failure, so as to influence the service life of bearing, traditional its service life of agricultural machinery hub bearing
Generally 3 months.
Utility model content
The purpose of this utility model is intended to overcome existing agricultural machinery hub bearing area of dissipation smaller and influence the use of bearing
The defect in life-span can increase the agricultural machinery hub bearing that area of dissipation improves bearing service life there is provided a kind of.
Therefore, the utility model uses following technical scheme：A kind of agricultural machinery hub bearing with radiator structure, including method
Blue disk outer ring, ring flange inner ring, rolling element, retainer, back-up ring, mandrel and sealing mechanism, rolling element are installed on by retainer
Between flange plate outer ring and ring flange inner ring, ring flange inner ring coordinates with mandrel to be installed, and back-up ring is provided with axial projection, and back-up ring coordinates
Its axial projection end face mutually reclines with ring flange inner ring end face when being set in mandrel, forms close between back-up ring and flange plate outer ring
Chamber is sealed, sealing mechanism is installed in annular seal space, and the flange plate outer ring is made up of the round plate and axial part being connected as a single entity, it is special
Levying is, the periphery of the flange plate outer ring axial part is provided with circular radiating groove, by setting circular radiating groove so that flange
The area of dissipation increase of disk outer ring periphery, improves radiating effect.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
Arc transition between the both sides cell wall and flange plate outer ring axial part periphery of the circular radiating groove, can increase
Area of dissipation, improves radiating effect.
The utility model can reach following beneficial effect：By setting annular to dissipate in flange plate outer ring axial part periphery
Heat channel so that the area of dissipation increase of flange plate outer ring axial part periphery, while reducing the wall of flange plate outer ring axial part
Thickness, can distribute the heat of Bearing inner, and good heat dissipation effect in time, bearing will not because its internal temperature is too high and fails,
The service life of bearing is improved, bearing service life was improved to 4 months from original 3 months, and bearing life improves 30%.
Brief description of the drawings
Fig. 1 is traditional agricultural machinery hub bearing cross-sectional view.
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, the utility model includes flange plate outer ring 1, ring flange inner ring 7, rolling element 6, retainer 5,
Back-up ring 3, mandrel 4 and sealing mechanism, rolling element 6 are installed between flange plate outer ring 1 and ring flange inner ring 7 by retainer 5, method
Blue disk inner ring 7 coordinates with mandrel 4 to be set with, and back-up ring 3 is provided with axial projection, its axial projection end when the engagement sleeves of back-up ring 3 are loaded on mandrel 4
Face is mutually reclined with the end face of ring flange inner ring 7, and annular seal space is formed between back-up ring 3 and flange plate outer ring 1, and sealing mechanism is installed on close
Intracavitary is sealed, the flange plate outer ring 1 is made up of the round plate and axial part being connected as a single entity, the axial part of the flange plate outer ring 1
Periphery be provided with circular radiating groove 2, between the both sides cell wall and the axial part periphery of flange plate outer ring 1 of circular radiating groove 2
Arc transition, by setting circular radiating groove 2 so that the area of dissipation of the periphery of flange plate outer ring 1 increases, while reducing method
The wall thickness of the blue axial part of disk outer ring 1 so that good heat dissipation effect.
