Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

In the description of the present invention, it is to be understood that the terms "one end", "the other end", "the outside", "upper", "inside", "horizontal", "coaxial", "central", "end", "length", "outer end", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Furthermore, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The use of terms herein such as "upper," "above," "lower," "below," and the like in describing relative spatial positions is for the purpose of facilitating description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the present invention, unless otherwise explicitly specified or limited, the terms "set", "coupled", "connected", "penetrating", "plugging", and the like are to be understood in a broad sense, and may be, for example, fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise.

As shown in fig. 1, the utility model discloses a special accurate axle core of micromotor, including axle core main part 4, an assembly cavity is respectively seted up to the one end both sides of axle core main part 4, an installation foil 1 of equal reassembling type in the assembly cavity, foil 1 parcel live the assembly cavity, and its outer wall and 4 parallel and levels of axle core main part form a clearance chamber between foil 1 and the assembly cavity bottom, and the clearance intracavity is provided with a confined filling layer 2, and filling layer 2 intussuseption is full of lubricating oil, is provided with more than one oil outlet 5 on the foil 1.

In this embodiment, as shown in fig. 2, one end of the oil outlet hole 5 is closed, the other end of the oil outlet hole is communicated with the clearance cavity, the inner diameter of the whole oil outlet hole 5 is gradually decreased from inside to outside, a sealing layer 51 is arranged at the outer end of the oil outlet hole 5, and the thickness of the sealing layer 51 is 0.2-0.6 mm. When the axle core is used at first, can lubricate by the manual work, as along with the continuous mode of axle core, the seal coat thins gradually, slowly, the oil outlet can switch on, the discharge that inside lubricating oil can not be, because oil outlet outside end aperture is little, the medial extremity is big, so the foil mode is more serious, the discharge capacity of lubricating oil is big more, this has just alleviateed the wearing and tearing volume with lubricating oil, avoid wearing and tearing too big problem, simultaneously, the lubricating oil that constantly gushes out can partly spill over to the outside, we can know the degree of wear of axle core through lubricating oil, can in time change the axle core, reach an automatic mesh of reminding.

In this embodiment, two ends of the metal sheet 1 respectively form an extension portion, and extension grooves are formed at positions corresponding to the extension portions on two sides of the assembly cavity, and the extension portions are buckled in the extension grooves. The bottom surface of the extending groove is provided with a first screw hole, a counter bore is arranged on the extending portion of the metal sheet 1 opposite to the first screw hole, a second screw hole is arranged on the bottom surface of the counter bore, and the screw 3 is fixed after passing through the first screw hole and the second screw hole. The filling layer 2 is made of oil absorption cotton material, and lubricating oil is filled in the oil absorption cotton. When the metal sheet is worn, the metal sheet can be detached and replaced with a new one without replacing the whole shaft core.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
