[0041] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. For simplicity of the disclosure, the description below refers to the drawings to illustrate specific embodiments in which the present application can be practiced. In a normal manner, the drawings are not necessarily to scale and the specific measurements are not necessarily provided. The same or similar characters refer to the same or similar parts throughout the several views of the drawings.

[0042] The embodiments of the present application will be described in detail below with reference to the drawings.

[0043] Referring to Figs. 1-3 The present application provides a floating ring 300 with constant inner diameter, comprising:

[0044] a ring-shaped base 310, which is sleeved on the first component 100 with constant inner diameter; and

[0045] a resilient receptor 320, which is connected to the outside of the ring-shaped base 310 and embedded in the second component 200;

[0046] Wherein, the resilient receptor 320 can be deformed to store stress under the action of radial force, and release the stress through radial floating at any angle of circumference after the radial force disappears to quickly center the first component 100 and the second component 200 to realize self-centering adjustment between them.

[0047] Specifically, the elastic receptor 320 includes a plurality of arc-shaped wings 321 distributed around the outer circumference of the annular base 310 and connected with the inner side wall of the second component 200, each arc-shaped wing 321 is connected with a protrusion 311 arranged on the outer circumferential surface of the annular base 310 at one end, and extends away from the center of the annular base 310 at the other end to form a floating gap between the inner concave surface of the arc-shaped wing 321 and the outer circumferential surface of the annular base 310. Under the action of the radial force, each arc-shaped wing 321 is extruded and deformed towards the floating gap, and the stress is stored through the elastic receptor 320; after the radial force disappears, the stress is released through the elastic recovery of each arc-shaped wing 321, thereby driving the first component 100 or the second component 200 to produce radial floating at any angle around the circumference, so that the first component 100 and the second component 200 are quickly re-centered to realize self-centering adjustment between them. That is, the radial floating of the first component 100 or the second component 200 at any angle around the circumference is realized by the deformation of the elastic receptor 320 connected to the outside of the annular base 310, the structure is greatly simplified, and maintenance and disassembly are convenient. Moreover, the annular base 310 and the elastic receptor 320 are arranged inside and outside, which can be used for different mechanical parts, has strong universal adaptability, and can effectively control the cost of accessories; at the same time, through the plurality of circumferentially distributed arc-shaped wings 321, the load received by the floating ring 300 can be uniformly dispersed to the annular base 310, ensuring uniform deformation of each arc-shaped wing 321, maintaining the reliability of the elastic recovery (elastic function of the elastic receptor 320) of each arc-shaped wing 321, enhancing the stability of the radial floating, and thereby ensuring the high-precision cooperation between the floating ring 300 and the first component 100 and the second component 200.

[0048] The protrusion 311 has a first arc-shaped surface 311a protruding outward, the arc-shaped wing 321 has a second arc-shaped surface 321a and a third arc-shaped surface 321b protruding outward, and the first arc-shaped surface 311a, the second arc-shaped surface 321a and the third arc-shaped surface 321b are sequentially connected; the inner concave surface of the arc-shaped wing 321 is a fourth arc-shaped surface 321c, and the fourth arc-shaped surface 321c is connected with the third arc-shaped surface 321b through a round corner 321d; the gap between the fourth arc-shaped surface 321c of one arc-shaped wing 321 and the first arc-shaped surface 311a of the adjacent protrusion 311 and the second arc-shaped surface 321a of the adjacent arc-shaped wing 321 is the floating gap. Under the action of the radial force, each arc-shaped wing 321 can be extruded and uniformly and symmetrically deformed towards the floating gap, thereby eliminating the eccentricity problem caused by machining errors and assembly deviations, and automatically adjusting the position of the first component 100 or the second component 200 during elastic recovery, thereby ensuring that the center axes of the two components are aligned (i.e., self-centering).

[0049] The projection of the fillet 321d of an arc-shaped wing plate 321 radially inward along the annular base 310 falls on the second arc-shaped surface 321a of the adjacent arc-shaped wing plate 321 from 1 / 3 of the second arc-shaped surface 321a away from the third arc-shaped surface 321b. In this way, one arc-shaped wing plate 321 can cover 2 / 3 of the second arc-shaped surface 321a of the adjacent arc-shaped wing plate 321, so that each arc-shaped wing plate 321 can form an overlapping state when pressed against each other, thereby ensuring that the deformation of each arc-shaped wing plate 321 to the floating gap is uniform and symmetrical.

[0050] In order to reduce the manufacturing cost of the floating ring 300 and ensure the connection strength of the arc-shaped wing plate 321 and the convex part 311 to prolong the service life of the floating ring 300, a plurality of arc-shaped wing plates 321 are integrally processed with the annular base 310. Specifically, to facilitate the processing of the floating gap between each arc-shaped wing plate 321 and the annular base 310, the first arc-shaped surface 311a is tangent to and concentric with the second arc-shaped surface 321a (i.e., they share a common circle), the circle on which the first arc-shaped surface 311a and the second arc-shaped surface 321a are located is eccentric to the inner circular surface of the annular base 310, the third arc-shaped surface 321b is concentric with the inner circular surface of the annular base 310, and the fourth arc-shaped surface 321c is eccentric to the inner circular surface of the annular base 310. The floating gap designed and processed in this way has a controllable radial elastic deformation amount, can allow the elastic receptor 320 (arc-shaped wing plate 321) to produce a slight displacement in the radial direction, thereby absorbing stress caused by vibration, thermal expansion or dynamic load, avoiding wear or failure caused by rigid contact; in addition, through the synergistic effect of elastic deformation and the precise dimensions of the parts themselves, the floating ring 300 can ensure the positioning accuracy between the first part 100 and the second part 200, significantly improving the reliability and service life of the system containing the first part 100 and the second part 200; furthermore, the third arc-shaped surface 321b concentrically arranged with the inner circular surface of the annular base 310 is in surface contact with the inner side wall of the second part 200, which can ensure effective transmission of power between the first part 100 and the second part 200.

[0051] The thickness of each arc-shaped wing plate 321 changes in the manner of first increasing and then decreasing along its extension direction (i.e., the direction gradually away from the center of the annular base 310 from the convex part 311). The thickness of each arc-shaped wing plate 321 is the largest (i.e., the thickest) at the connection between the second arc-shaped surface 321a and the third arc-shaped surface 321b. In this way, when one arc-shaped wing plate 321 is pressed against the adjacent arc-shaped wing plate 321, the fillet 321d on the arc-shaped wing plate 321 can be completely accommodated in the corresponding floating gap after deformation, further ensuring that each arc-shaped wing plate 321 can produce uniform and symmetrical deformation.

[0052] The arc-shaped wing plates 321 are evenly distributed around the outer circumference of the annular base 310.

[0053] In the embodiment, the arc-shaped wing plates 321 are evenly distributed around the outer circumference of the annular base 310.

[0054] The first component 100 is a shaft component (such as a shaft core), and the second component 200 is a hole component (such as a sleeve).

[0055] In summary, the floating ring 300 is applicable to the connection of shaft and hole components in a precision transmission system, and is also applicable to a floating joint for compensating dynamic deviation in an automatic device, a damping and buffering element in a high-vibration environment, and other occasions requiring high-precision centering and allowing radial floating.

[0056] The above embodiments are only preferred embodiments of the present application, and are not a limitation on the technical solutions of the present application. Any technical solution that can be realized on the basis of the above embodiments without creative labor should be considered to fall within the protection scope of the patent of the present application.
