Abstract
The utility model relates to an automatic wiper, including the axle sleeve, the inner wall of axle sleeve is opened there is the air duct that switches on, be equipped with on the axle sleeve with the inlet port that the air duct switched on. The novel air-floating shaft sleeve is low in friction coefficient and small in vibration, and is suitable for a bearing rotating at a high speed.
Description
Technical Field
The utility model relates to a machine parts field particularly, relates to an air supporting axle sleeve.
Background
The bearing is an important part in the mechanical field, and has the main functions of supporting a mechanical rotating body, reducing the friction coefficient in the motion process of the mechanical rotating body and ensuring the rotation precision of the mechanical rotating body.
Therefore, the reduction of the friction coefficient is always the goal of the component, and the vibration during the rotation of the bearing is one of the problems to be avoided as much as possible.
Disclosure of Invention
In order to achieve the above object, the technical solution adopted in the present novel embodiment is as follows:
the embodiment of the utility model provides an air supporting axle sleeve, a serial communication port, including the axle sleeve, the inner wall of axle sleeve is opened there is the air duct that switches on, be equipped with on the axle sleeve with the inlet port that the air duct switched on.
Furthermore, the air grooves are symmetrically distributed on the inner wall of the shaft sleeve.
Further, the air groove comprises a circumferential transverse groove and an axial vertical groove.
Furthermore, the air inlets are communicated with the air groove along the radial direction, and the number of the air inlets is two or more, and the air inlets are uniformly distributed along the circumferential direction of the shaft sleeve.
Further, the number of the air inlet holes is three.
Compared with the prior art, the novel embodiment has the following beneficial effects:
this is novel through injecting compressed air in the gas tank, with axle center air supporting in the axle sleeve, has reduced axle center pivoted friction and vibrations.
Drawings
The invention is further described with reference to the following figures and examples.
Figure 1 is a schematic view of the present invention.
FIG. 2 is a schematic sectional view A-A shown in FIG. 1.
In the figure: 1 is an air inlet, 2 is a transverse groove, 3 is a vertical groove, and 4 is a shaft sleeve.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings, which illustrate the basic structure of the present invention only in a schematic manner, and therefore show only the constitution relating to the present invention.
Referring to fig. 1 and 2, the present embodiment provides an air-floating shaft sleeve, which includes a shaft sleeve, an air groove is formed on an inner wall of the shaft sleeve 4, and an air inlet 1 communicated with the air groove is formed on the shaft sleeve 4. When the air-floating type air-floating sleeve is used, compressed air is continuously introduced through the air inlet holes 1, so that the axis in the shaft sleeve 4 forms an air-floating state, and the friction and the vibration during the rotation of the axis are reduced. The pressure of the compressed air is generally 0.5MPa or more.
Preferably, the gas tank includes horizontal groove 2 and the axial of circumference and erects groove 3, and horizontal groove 2 switches on the equipartition each other on the inner wall with erecting groove 3, convenient processing. The air inlet 1 penetrates through the shaft sleeve 4 along the radial direction, so that the processing is convenient.
The number of the air inlets 1 is two or more, preferably three, and the air inlets are uniformly distributed on the shaft sleeve 4 along the circumferential direction.
This neotype beneficial effect passes through the air pocket with axle center air supporting in axle sleeve 4 for compressed air, reduces frictional force and vibrations when the axle center rotates.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The term "inside the housing" refers to the cavity enclosed by the housing, not the area between the inner and outer surfaces of the housing, and the specific meaning of the above terms in the present invention can be understood by those skilled in the art.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
