Abstract
The utility model relates to an end cover structure for an oil bearing, which belongs to the technical filed of motor production. The utility model comprises an oil bearing, an end cover and a bearing clip. The end cover is provided with a bearing chamber. One end of the oil bearing is assorted inside the bearing chamber, while the outer frame of the other end of the oil bearing is pressed tightly through the bearing clip. The end cover is provided with at least two rivets which are integrated with the end cover into a whole. The bearing clip is provided with a plurality of riveting holes which are assorted with the rivets. The oil bearing, the end cover and the bearing clip are fixed with the riveting holes through the rivets. The utility model has the advantages of few components and high fixity and reliability of the riveting, and solves the problems of comparatively large quantities of the components and poor fixity and reliability of the riveting.
Description
Technical field
The utility model relates to a kind of oil containing bearing end cover structure, belongs to the technical field that motor is manufactured.
Technical background
China's utility model patent specification (publication number: CN2574289) disclose a kind of iron(-)clad motor oil containing bearing end cover mechanism, it includes end cap, bearing, bearing gland, bearing shell fragment and lubricant grease, bearing is located in the bearing chamber of end cap, the bearing shell fragment is pressed on the bearing, bearing gland covers on bearing, lubricant grease is poured in around the bearing between bearing gland and the end cap, corresponding through hole is set respectively on end cap, bearing shell fragment and bearing gland, adopts rivet together again three's riveted and fixed.Said structure need adopt additional rivet, has caused the increase of number of components, and the reliability of riveted and fixed is also relatively poor simultaneously.
Summary of the invention
The utility model purpose is to provide a kind of number of components less, the oil containing bearing end cover structure that the riveted and fixed reliability is higher, problem such as it is more to have solved the number of components that existing oil containing bearing end cover structure exists, and the riveted and fixed reliability is relatively poor.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises oiliness bearing, end cap and bearing folder, described end cap is provided with bearing chamber, oiliness bearing one end is engaged in the bearing chamber, described oiliness bearing other end outline is tight by the bearing cramping, form at least 2 riveting points with the end cap one on the described end cap, described bearing folder is provided with some riveted holes that cooperate with riveting point, and oiliness bearing, end cap and bearing folder three are fixed together by riveting point and riveted holes.The riveting point and the end cap of the utility model and the riveted joint of bearing folder are structure as a whole, rivet that need not be extra, simplified the syndeton of bearing and end cap, also improved the reliability of riveting between bearing and the end cap simultaneously, promptly improved the reliability of oiliness bearing in end cap bearing indoor positioning.
As preferably, described end cap is put side depression corresponding to riveting point position to riveting.Wherein, the riveting point can be formed to the another side punching press by one side of end cap, thereby forms depression from a side to riveting that put at the corresponding end cap opposite side of riveting point, simultaneously, riveting point also can with end cap one die cast.
As preferably, the quantity of described riveting point is 2-5.Wherein, the quantity of riveting point can be selected according to the size of oiliness bearing, and generally speaking, the oiliness bearing diameter is bigger adopts a fairly large number of riveting point, the riveting point that then can adopt negligible amounts that the oiliness bearing diameter is less.
As preferably, described bearing chamber bottom is provided with wear-resistant gasket, described wear-resistant gasket and oiliness bearing axis normal.Wear-resistant gasket can be avoided direct contact the between motor shaft end and end cap, thereby reduces the wearing and tearing between motor shaft end and the end cap.
As preferably, the outer surface of described oiliness bearing is the little spherical interior surface of the big two ends of mid diameter diameter and forms, described bearing chamber inner surface is the spherical interior surface shape that cooperates with oiliness bearing one end, and described bearing folder forms the spherical interior surface shape that cooperates with the oiliness bearing other end with the oiliness bearing contact portion.The oiliness bearing two ends bearing chamber of the shape by spherical interior surface and end cap and bearing respectively cooperate between pressing from both sides, can keep concentricity good between oiliness bearing and the end cap, thereby the rotating shaft that prevents its swivel bearing obtains good concentric supporting, reduces the circular runout of rotating shaft.
Therefore, it is less to the utlity model has number of components, and the riveted and fixed reliability is than characteristics such as height.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, comprise oiliness bearing, end cap and bearing folder, end cap 1 is provided with bearing chamber 2, the surface of bearing chamber 2 is sphere shape, oiliness bearing 3 one ends that outer surface is the little spherical interior surface shape of the big two ends of mid diameter diameter are engaged in the bearing chamber 2, the bearing chamber inner surface is the spherical interior surface shape that cooperates with oiliness bearing one end, oiliness bearing 3 other end outlines are compressed by bearing folder 4, the bearing folder forms the spherical interior surface shape that cooperates with the oiliness bearing other end with the oiliness bearing contact portion, form 2 riveting points 5 with the end cap one by a surface of end cap to another surperficial punching press of end cap on the end cap 1, end cap is put side depression corresponding to riveting point position to riveting, bearing folder 4 is provided with 2 riveted holes 6 that cooperate with riveting point 5, oiliness bearing 3, end cap 1 and bearing press from both sides 4 threes and are fixed together by riveting point 5 and riveted holes 6.Bearing chamber 2 bottoms are provided with wear-resistant gasket 7, the axis normal of wear-resistant gasket 7 and oiliness bearing 3.
