Abstract
The utility model discloses a radial air bearing elastic support structure, including journal bearing elastic support and bearing housing, journal bearing elastic support is last to be provided with the elastic groove, and the center of bearing housing is provided with the installation cavity. This radial air bearing elastic support structure sets up the elasticity groove through setting up on radial bearing elastic support, can reach the effect of guaranteeing the installation accuracy and playing the bradyseism to improve the stability of machine operation.
Description
Technical Field
The utility model relates to a bearing structure technical field specifically is radial air bearing elastic support structure.
Background
The bearing is used as the main part of the rotator, its main function is to support the mechanical rotator, reduce the friction coefficient in the movement process and ensure the rotation precision, the types of the bearing are many, the air bearing is one of the sliding bearing types, the air bearing is also called as the air bearing, it refers to the sliding bearing using air as the lubricant, the most commonly used gas lubricant is air, nitrogen, argon, hydrogen, helium or carbon dioxide can be used according to the need, the air bearing provides the high radial and axial rotation precision, because there is no mechanical contact, the abrasion degree is reduced to the lowest, thereby ensuring the precision to be always stable, the low shearing force in the air bearing can provide the high rotation speed, simultaneously, the power loss is reduced to the lowest, and the generated heat is very small, and the bearing is widely applied to hovercraft, textile machinery and cable machinery, Instrument machines, gas circulators, etc., and an air bearing elastic support structure is important in order to prevent the air bearing from vibrating and deforming.
The prior art has the following defects or problems:
the existing radial air bearing adopts an O-shaped ring positioning adjusting bearing, and the O-shaped ring is soft in material compared with metal, low in rigidity and poor in positioning precision, so that the application range of the O-shaped ring is limited, the O-shaped ring is difficult to apply to instruments or equipment with high strength and high precision, the O-shaped ring made of rubber is short in service life, and the O-shaped ring is quite seriously worn and needs to be replaced frequently in the application process, so that the waste and the replacement are troublesome.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide radial air bearing elastic support structure to the weak point to prior art to O type circle material that proposes in solving the background art is soft, and rigidity is low, the poor problem of positioning accuracy.
In order to achieve the above object, the utility model provides a following technical scheme: radial air bearing elastic support structure, including radial bearing elastic support and bearing housing, be provided with the elastic slot on the radial bearing elastic support, and the center of bearing housing is provided with the installation cavity.
As the preferred technical scheme of the utility model, the journal bearing elastic support is the shape of bilateral symmetry about its center.
As the preferred technical scheme of the utility model, radial bearing elastic support cup joints on the bearing housing.
As the preferred technical scheme of the utility model, journal bearing elastic support and bearing housing have common central line.
Compared with the prior art, the utility model provides a radial air bearing elastic support structure possesses following beneficial effect:
the radial air bearing elastic support structure has the function of elastic support by arranging the elastic groove on the radial bearing elastic support, meanwhile, the structure plays a role in accurately positioning the rotor, when the rotor runs, not only can ensure the installation precision, but also can play the roles of cushioning and adjusting, the strength of the radial air bearing elastic supporting structure is greatly improved compared with a rubber O-shaped ring, and the elastic groove can absorb the transmitted vibration to play the role of cushioning, the larger the elastic groove is in a certain range, the stronger the shock resistance of the elastic support of the radial bearing is but the strength is reduced, the strength of the elastic support of the radial bearing can be changed within a certain range by changing the size and the number of the elastic grooves according to requirements, the utility model discloses a soft, the rigidity is low, the poor problem of positioning accuracy of O type circle material has effectively been solved.

FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of the structure of the present invention.
In the figure: 1. the radial bearing is elastically supported; 2. a bearing housing; 3. an elastic groove; 4. and (7) installing a cavity.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, in this embodiment: radial air bearing elastic support structure, its characterized in that: including radial bearing elastic support 1 and bearing housing 2, be provided with elastic groove 3 on the radial bearing elastic support 1, and the center of bearing housing 2 is provided with installation cavity 4.
In this embodiment, radial bearing elastic support 1 is bilateral symmetry's shape about its center, and radial bearing elastic support 1 cup joints on bearing housing 2 to installation and dismantlement, radial bearing elastic support 1 and bearing housing 2 have common central line, and it is the same to guarantee that each direction of radial air bearing receives the power of rotor when installing the use.
The utility model discloses a theory of operation and use flow: during the installation with journal bearing elastic support 1 cup joint on bearing housing 2, peg graft the bearing again with in the installation cavity 4, then cup joint the rotor on journal bearing elastic support 1, the rotor utilizes elastic groove 3 to absorb its vibrations that transmit journal bearing elastic support 1 during operation to play the effect of bradyseism, the utility model discloses simple structure can adjust the rigidity of bearing through the size of adjusting elastic groove 3, thereby changes its rigidity according to the different rigidity demands on the different equipment and reach fine matching effect, makes the more stable of machine operation.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. 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.
