Abstract
The utility model discloses a stud shaft roller bearing lubricated with thin oil in the sealed ambient environment, the bearing capable of being lubricated while not hindering normal operation of the equipment. The bearing comprises a bearing external washer, a rolling body, a case, a loose ring and a supporting shaft, wherein one end of the supporting shaft is flange with at lease two notches on the circumference thereof. The circle tangential to the circumferential notch bottom of the flange is centrally circled with the center of the flange for the supporting shaft, and the minimum diameter thereof is no less than the diameter of the internal rollaway. The thin oil, in splashing lubrication, is introduced from the circumferential notch of the flange for the supporting shaft into the rolling body of the roller bearing and the rollaway of the bearing external washer for lubrication of the roller bearing.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of bolt axis bearing of thin oil lubricant, belongs to technical field of bearings.
Background technique
The lubricating fitting of existing bolt axis roller bearing comprises that the bolt axis two ends press-fit forced filling oil cup, is communicated with the center axial hole at bolt axis two ends, the radially a plurality of oilholes that are communicated with the center axial hole of bolt axis.Inject the solid lubrication grease by forced filling oil cup to bolt axis central shaft through hole, this solid lubrication grease flows along bolt axis center axial hole, and the radial direction oil hole by bolt axis imports the inside and outside raceway lubricating bearings of bearing again.The bearing of this use solid lubrication grease lubrication is adapted to be mounted within the packing less working environment, and the Bearing Installation of some machinery is in the working environment of sealing relatively, need under the situation that does not influence the equipment proper functioning, be lubricated bearing, obviously, the solid lubrication grease lubrication device of existing bolt axis roller bearing has been not suitable for this working condition requirement.
Summary of the invention
The utility model provides a kind of bolt axis roller bearing that adopts thin oil lubricant in the working environment of sealing relatively, can be lubricated bearing under the situation that does not influence the equipment proper functioning.
The purpose of this utility model is achieved by the following technical programs.
A kind of thin oil lubricant bolt axis roller bearing, comprise bearing outer ring, rolling element, retainer, loose rib, supporting axle, described supporting axle one end is a flange, the other end is a bolt arrangement, the endoporus of described loose rib is fixedlying connected of interference fit with supporting axle, the flange of described supporting axle and loose rib are to the retainer axially locating, and the flange of described supporting axle circumferentially has two breach at least.
With the tangent circle in the circumferential breach of flange bottom be that center with described supporting axle flange is the center of circle, the diameter of raceway in its minimum diameter is not less than.
Advantage of the present utility model is: be installed in the roller bearing in the working environment of relative sealing, owing to fill thin oil in the oil sump of sealing, can be by the mode of splash lubrication, thin oil is lubricated roller bearing from the rolling element of the circumferential indentation, there importing roller bearing of supporting axle flange and the raceway of bearing outer ring, thereby solved the lubrication problem of the situation bottom roller bearing that runs well at equipment.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a broken section structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
Among the embodiment as depicted in figs. 1 and 2, the utility model comprises bearing outer ring 1, rolling element 2, retainer 3, loose rib 4, supporting axle 5.Described supporting axle 5 one ends are flanges 51, and the other end is a bolt arrangement, and the endoporus 41 of described loose rib 4 is fixedlying connected of interference fit with supporting axle 5, and the flange 51 of described supporting axle 5 circumferentially has two breach 52 at least.
With the tangent circle 54 in circumferential breach 52 bottoms of flange 51 be that center with the flange 51 of described supporting axle 5 is the center of circle, the diameter of raceway 53 in its minimum diameter is not less than.
In the present embodiment, the flange 51 of supporting axle 5 circumferentially has three equally distributed circular arc cutaway 52, because circular arc cutaway 52 comes out the outer raceway 11 and the part rolling element 2 of bearing outer ring 1, under the situation that equipment runs well, thin oil can be by the mode of splash lubrication, import from circular arc cutaway 52 that roller bearings are exposed to the rolling element 2 at this place and the outer raceway 11 of bearing outer ring 1 lubricate roller bearing, thereby solved lubrication problem at the situation lower bearing of equipment normal operation.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
