Abstract
The utility model mainly relates to a bearing retaining frame with the function of collecting and dredging lubricating oil, which belongs to the technical field of bearings. A collecting groove (2) with the effect of collecting the oil is arranged on the inner diameter of the retaining frame (1), the bottom surface of the collecting groove (2) is an inclined surface, and the bottom surface of the collection groove with a certain inclination angle forms a dredging surface (3) of the lubricating oil. The bearing retaining frame with the function of collecting and dredging lubricating oil provided by the utility model guides the lubricating oil with insufficient pressure into the bearing rolling surface and the guide surface when the retaining frame rotates at a high speed, lubricating oil films are formed on the rolling surface and the guide surface, rolling bodies and rolling passages are separated from the retaining frame and a bearing sleeve ring, the friction loss is reduced, at the same time, the heat generated by friction is brought away, temperature inside the bearing is reduced, and the utility model is favorable for prolonging the service life of the bearing and reducing the cost.
Description
Technical field
The utility model belongs to technical field of bearings, relate generally to a kind of have collect and dredge the retainer of lubricant oil function.
Background technique
Oil jet lubrication is one of primary lubricant mode of aeroengine main shaft bearing, forcing oil jet lubrication is directly to spray to bearing face from lubricating oil pump along spray bar, can effectively be lubricated bearing inside rolling surface and guiding surface, form lubricant film at rolling surface and guiding surface, rolling element and raceway and retainer and bearing ring are separated, fricative heat is taken away in the wearing and tearing of reducing friction simultaneously, reduces the bearing inside temperature.But the oil jet lubrication of some engine bearing is not enforceable, lubricant oil is the centrifugal action that produces when leaning on the engine spindle high speed rotating, cavity wall along engine interior flows to the oil-collecting part, spray to bearing face by the hole on this part again, thereby realize the oil jet lubrication to bearing, injection pressure is little with respect to forcing oil jet lubrication, can cause bearing two ends lubrication effect different, promptly an end has lubricant oil, the other end oil-poor (insufficient lubrication).
Summary of the invention
The purpose of this utility model be propose a kind of have collect and dredge the retainer of lubricant oil function, the lubricant oil that sprays to bearing under the centrifugal action is collected bearing inside, simultaneously lubricant oil is dredged, make lubricant oil flow to the other end from the end face that enters bearing, thereby it is evenly lubricated that bearing inside is obtained, and improves lubrication effect.
The utility model is finished the technological scheme that its invention task taked:
A kind of have collection and dredge the retainer of lubricant oil function, has the collection groove of collecting the oil effect on the internal diameter of described retainer, the bottom surface of described collection groove is an inclined-plane, and described collection groove has the face of dredging of the bottom surface formation lubricant oil at certain angle of inclination.
The retainer of lubricant oil function is collected and is dredged in having of the utility model proposes, during the retainer high speed rotating, the lubricant oil of underpressure is directed to bearing element surface and guiding surface, form lubricant film at rolling surface and guiding surface, rolling element and raceway and retainer and bearing ring are separated the wearing and tearing of reducing friction, take away fricative heat simultaneously, reduce the bearing inside temperature, help prolonging the bearing working life-span, reduce cost.
Description of drawings
Fig. 1 is the view of the utility model on main shaft bearing.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the A-A sectional drawing of Fig. 2.
Among the figure: 1, retainer, 2, collection groove, 3, dredge face, 4, lubricant oil, 5, rolling surface, 6, guiding surface.
Embodiment
With embodiment the utility model is illustrated in conjunction with the accompanying drawings:
As shown in Figure 1, and with reference to Fig. 2, Fig. 3, a kind of have collection and dredge the retainer of lubricant oil function, be arranged between Main Shaft Bearing of Engine inner ring and the outer ring, can be with the main shaft high speed rotating, have the collection groove 2 of collecting the lubricant oil effect on the internal diameter of retainer 1, the bottom surface of described collection groove is an inclined-plane, and described collection groove has the face of dredging 3 of the bottom surface formation lubricant oil at certain angle of inclination; Make lubricant oil can flow to the other end of bearing from an end of bearing.
When lubricant oil 4 sprays to bearing by centrifugal force, when entering the retainer inside diameter surface of high speed rotating, lubricant oil flows along retainer 1 inside diameter surface, enters rolling surface 5 and guiding surface 6 from the pocket hole, finishes the evenly lubricated of bearing, the wearing and tearing of reducing friction.
Claims (1)
1. one kind has collection and dredges the retainer of lubricant oil function, it is characterized in that: have the collection groove (2) of collecting the oil effect on the internal diameter of described retainer (1), the bottom surface of described collection groove (2) is an inclined-plane, and described collection groove has the face of dredging (3) of the bottom surface formation lubricant oil at certain angle of inclination.
