Abstract
The utility model relates to a lubricating structure with pin-hole oil spray for non-working surfaces of a bearing, comprising an oil spray hole and a tool recess communicated with the working surface of a bearing track; wherein, the oil spray hole is communicated with the tool recess. The lubricating structure with pin-hole oil spray for non-working surfaces of the bearing solves the problems of early fatigue and failure of the bearing as a result of stress concentration at the edges of the oil holes caused by the larger size of the existing oil holes (with diameter of more than 1mm).
Description
Technical field
The utility model relates to a kind of bearing non-working surface pin hole oil jet lubrication structure.
Background technique
Bearing needs oil spout or oil mist lubrication in running up, for making lubricant oil directly be sprayed onto the part surface of bearing, often opening several nozzle openings 1 on the roller surface of bearing, the quantity of oilhole and diameter are determined according to the need oil mass, though solved lubrication problem like this, but, because more than the big 1mm of oilhole diameter, and on the working surface of bearing, in the bearing operation process, because rolling element rolling on raceway working surface 3, form stress near the oilhole and concentrate, cause tired source, make bearing at first near oilhole, peel off, cause bearing failure, see Fig. 1.
The model utility content
Technical problem to be solved in the utility model is: at the problem of above-mentioned existence, provide a kind of bearing non-working surface pin hole oil jet lubrication structure that reduces the bearing failure degree.
The utility model is achieved in that
A kind of bearing non-working surface pin hole oil jet lubrication structure, comprise nozzle opening, with the tool withdrawal groove that the bearing race working surface communicates, described nozzle opening communicates with described tool withdrawal groove.
The diameter of described nozzle opening is less than 1mm.
Described nozzle opening communicates with described tool withdrawal groove by the pin hole of diameter less than 1mm.
The position of opening of described tool withdrawal groove is positioned at the non-stress zone.
The beneficial effects of the utility model:
According to the technical solution of the utility model, because the needle-like aperture is opened in tool withdrawal groove, not on bearing working face, avoided stress to concentrate, also just avoided occurring near the peeling off of oilhole, prolonged the working life of bearing.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is existing bearing working face oil jet lubrication structure.
Fig. 2 is a structural representation of the present utility model.
Embodiment
According to Fig. 2, in the utility model bearing non-working surface pin hole oil jet lubrication structure, nozzle opening 4 communicates with tool withdrawal groove 2 on the bearing race working surface 3 by pin hole 1, and the diameter of pin hole 1 is less than 1mm.
During work, lubricant oil or mist of oil enter out the nozzle opening 4 at bearing bore diameter (then opening at external diameter at overcoat as rib), by uniform pin hole 1, enter the tool withdrawal groove 2 of bearing inside, and the revolution by rolling element with bring bearing race working surface 3 into from handle lubricant oil.
Claims (4)
1, a kind of bearing non-working surface pin hole oil jet lubrication structure, comprise nozzle opening, with the tool withdrawal groove that the bearing race working surface communicates, it is characterized in that: described nozzle opening communicates with described tool withdrawal groove.
2, bearing non-working surface pin hole oil jet lubrication structure according to claim 1, it is characterized in that: the diameter of described nozzle opening is less than 1mm.
3, bearing non-working surface pin hole oil jet lubrication structure according to claim 1, it is characterized in that: described nozzle opening communicates with described tool withdrawal groove by the pin hole of diameter less than 1mm.
4, according to claim 1 or 3 described bearing non-working surface pin hole oil jet lubrication structures, it is characterized in that: the position of opening of described tool withdrawal groove is positioned at the non-stress zone.
