Abstract
The utility model discloses a high-efficiency lubricating oil slinger for a sliding bearing, which relates to a body (1) of the oil slinger. The inner surface (2) of the body (1) is a curved surface in arc connection, which at least comprises two sections of arcs in connection. The inner ring surface of the body is in contact fit with a lubricating shaft, namely line contact in the prior art is changed into surface contact, the inner ring surface is the curved surface, and the contact area is enlarged, so that the inner ring surface is full in oil discharge; meanwhile, an enough friction force is generated to drive the oil slinger to make micro vibration on the shaft, and thus the oil discharge rate of the whole oil slinger is improved. Blind hole type oil grooves are formed in two sides of the body, so that the oil carrying quantity of the oil slinger increases. The high-efficiency lubricating oil slinger is simple in structure, stable and reliable in operation, easy to detach and mount, large in oil carrying quantity and reliable in lubrication and is particularly suitable for a large sliding bearing lubricating structure of a high-power high-voltage synchronous motor, the lubricating effect is improved, and the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to the bearing lubrication technical field, is specifically related to a kind of high-efficiency lubricating disc for sliding bearing.
Background technique
In the prior art sliding bearing lubricating structure, be widely used disc as the lubrication oil supply device, under middle and slow speed of revolution, disc can both fully provide bearing required lubricant oil, but under high rotating speed, the fuel delivery of disc often can not satisfy the needs of bearing sufficient lubrication, cause the bearing lubrication deficiency and serious wear, rate of fault raises, so that equipment damages too early, increases maintenance cost.For this reason, develop a kind of simple in structurely, the disc that can effectively increase fuel delivery under the high speed operation state is the key point that solves this problem.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and working stability is reliable, can effectively increase the high-efficiency lubricating disc that is used for sliding bearing of fuel delivery under the high speed operation state.
The purpose of this utility model is achieved in that the body that relates to ring, and the curved surface that the surface connects for circular arc within the described body, the curved surface of described circular arc connection comprise at least by two sections circular arcs and being formed by connecting.
The utility model ring body inner ring surface cooperates with the lubricated touch that is coupling, i.e. line contact by prior art becomes the face contact, and inner ring surface is curved surface, area of contact increases so that the inner ring surface emptying is more abundant, produce simultaneously enough frictional force drive discs and do microvibration at axle, improved the emptying rate of whole disc.The blind-hole type oil groove of body both sides, the band oil mass of increase disc.The utility model is simple in structure, working stability is reliable, is easy to remove and install, and the band oil mass is lubricated greatly reliable, is specially adapted in the large-scale bearing lubricating structure of high-power high voltage synchronous motor.
Description of drawings
Fig. 1 is the utility model plan view;
Fig. 2 is that the utility model A-A is to view;
Among the figure: the body of 1-ring, 2-internal surface, 3-outer surface, 4-side, 5-blind-hole type oil groove.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1 and Figure 2, the utility model relates to the body 1 of ring, and the curved surface that surface 2 connects for circular arc within the described body 1, the curved surface of described circular arc connection comprise at least by two sections circular arcs and being formed by connecting.
The curved surface that described circular arc connects comprises at least by 4 ~ 6 sections circular arcs and being formed by connecting, and described radius of arc is 30 ~ 70% of the radius of ring.
A blind-hole type oil groove 5 is set respectively on the bi-side 4 of the body 1 of described ring at least.
Described blind-hole type oil groove 5 is inclined hole, the outer rim of oblique ring, and its axis and ring body side plane are less than 90 °.
Described blind-hole type oil groove 5 is inclined hole, the outer rim of oblique ring, and the angle between its axis and ring body side plane is 30 ~ 50 °.
The degree of depth of described blind-hole type oil groove 5 is less than 50% of the thickness of the body 1 of ring.
The blind-hole type oil groove 5 of the both sides of described side 4 is crisscross arranged.
Described blind-hole type oil groove 5 is distributed in side 4, and is 4 ~ 6.

The body 1 of described ring is comprised of two semicircular ring, is the affixed cooperation of reassembling type between two rings, makes dismounting easier.
The utility model working principle and working procedure:
The utility model ring body inner ring surface cooperates with the lubricated touch that is coupling, i.e. line contact by prior art becomes the face contact, and inner ring surface is curved surface, area of contact increases so that the inner ring surface emptying is more abundant, produce simultaneously enough frictional force drive discs and do microvibration at axle, improved the emptying rate of whole disc.The blind-hole type oil groove of body both sides, the band oil mass of increase disc.
The utility model disc with the process of axle rotation in, the inside and outside surface of two side planes and disc takes up lubricant oil jointly, then flows to the surface of axle under the effect of gravity, frictional force etc., realizes lubricated between axle and bearing shell.
