Detailed Description

In order to make the technical solutions of the present invention better understood, the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-4, the present embodiment includes a disc-shaped gasket body 1, a wavy elastic layer 11 is disposed on a side disc surface of the gasket body 1, the elastic layer 11 is disposed on a side close to the shafting structure 2, and a hole 12 matched with the shafting structure 2 is disposed in a middle of the gasket body 1.

By adopting the structure, the elastic layer 11 of the elastic adjusting gasket can better offset the gap between the shafting structure 2 and the shell 4 so as to ensure the gap requirement during initial assembly; when the shafting structure 2 provided with the elastic adjusting gasket bears the working load, the axial load borne by the conical bearing of the shafting structure 2 can be absorbed by the elastic adjusting gasket in an elastic deformation mode, so that the shafting structure 2 is always in a good running state, the bearing range of the shafting structure 2 is increased, the noise, vibration and sound vibration roughness performance of the shafting structure 2 is improved, and the service lives of the bearing 22 and the shafting structure 2 are prolonged.

As shown in fig. 1 and 2, the gasket body 1 is a disc-shaped structure with a hole 12 at the center, the disc surface on one side of the disc-shaped structure is provided with an elastic layer 11, and the elastic layer 11 is integrally of a wavy structure, so that when the gasket body is extruded by a load and the like, the deformation caused by extrusion can be released into a wave trough, and the axial gap between the shafting structure 2 and the shell 4 is ensured through elastic deformation, so that the noise, vibration and acoustic vibration roughness performance is improved.

It should be noted that, the elastic layer 11 is of a wave-shaped structure as a whole, which means that the surface profile of the radial section thereof is of a wave shape, and the wave shape means a shape having continuous fluctuation or continuous concave-convex, as shown in fig. 2, the wave shape in this embodiment is a circular arc-shaped or semicircular structure having continuous fluctuation, and the circular arc-shaped or semicircular elastic layer 11 has sufficient strength compared with other wave-shaped structures, which not only ensures that the gasket body 1 has a certain deformability, but also meets the requirement of the gasket body 1 for supporting the gap between the shafting structure 2 and the housing 4.

It is understood that the wave shape of the elastic layer 11 may be other shapes besides circular arc or semi-circular shape, and the specific wavelength, thickness, curvature, etc. of the wave shape may be freely selected when the wave shape is selected, which is not limited in the present invention, and it is needless to consider the parameters such as curvature when the continuously undulating straight shape is adopted, for example, the wave shape may be a triangle with continuously undulating changes, and the deformability of the shape is strong; the wave shape can also be a continuous concave-convex rectangle, and the strength of the shape is higher.

In addition, the specific size of the hole 12 of the gasket body 1 should be determined according to the structure of the shafting structure 2 in practical application, and the utility model is not limited thereto as long as the hole does not interfere with the normal operation of the shafting structure 2.

In this embodiment, the elastic layer 11 is made of carbon steel or cadmium-plated steel, which has high durability, hardness, toughness, and the like, and has a certain elasticity, so that the elastic adjusting gasket can meet the use requirement of the elastic adjusting gasket even when the thickness is thin, and the cost is low. Of course, the material of the elastic layer 11 and the thickness of the gasket body 1 are determined according to the requirements of practical applications, and particularly, the requirements are determined according to the type and structure of the bearing 22, the magnitude of the pressing force of the shafting structure 2, and the like, which is not limited in the present invention.

The spacer 3 is a common spacer described in the background art, and the same applies hereinafter. As shown in fig. 4, a in fig. 4 is a bearing pre-tightening amount range that the adjustment shim 3 can be applied to when having a certain thickness, and B is a bearing pre-tightening amount range that the elastic adjustment shim provided in this embodiment can be applied to when having a certain thickness, and it can be known from the figure that, when the thicknesses of the elastic adjustment shim and the adjustment shim are the same, because the elastic adjustment shim has a certain elasticity, this embodiment can adapt to a working condition that an axial clearance amount between the shafting structure 2 and the housing 4 is larger, an ideal range during pre-tightening installation is larger, and the bearing 22 can also work normally under conditions such as larger axial load bearing range or larger deformation caused by temperature change.

Referring to fig. 3, the conical bearing seat structure of the present invention further includes a shaft structure 2, an elastic adjusting shim, an adjusting shim 3 and a housing 4, where the elastic adjusting shim is the elastic adjusting shim described above, and since the elastic adjusting shim has the above technical effects, the conical bearing seat structure including the elastic adjusting shim should also have the same technical effects, and thus, the description thereof is omitted here.

In this embodiment, an elastic adjusting shim is arranged between one end of the shafting structure 2 and the housing 4, and an adjusting shim 3 is arranged between the other end of the shafting structure and the housing 4, that is, the elastic adjusting shim is only arranged on one side of the shafting structure 2, and the common adjusting shim 3 is arranged on the other side.

As shown in fig. 3, in the present embodiment, an elastic adjusting shim is disposed at the left end of the shafting structure 2, and an adjusting shim 3 is disposed at the right end. After the elastic adjusting gasket is arranged, because the elastic adjusting gasket has certain elasticity, a margin can be formed between the shafting structure 2 at the end and the shell 4, the adjusting gasket 3 arranged at the other end is fixed by the pretightening force of the bearing, and the elastic deformation at one end of the elastic adjusting gasket can effectively offset the gap at one end of the adjusting gasket 3, so that the shafting structure 2 keeps certain balance under the action of the pretightening force of the bearing to keep normal operation.

It should be noted that the two ends of the shafting structure 2 cannot be set as elastic adjusting gaskets, otherwise, both ends of the shafting structure 2 have allowance, so that gaps occur at both ends of the shafting structure 2, the stress is not uniform, and the service life is reduced. Of course, which end of the shafting structure 2 is provided with the elastic adjusting shim, and which end is provided with the adjusting shim 3, can be selected according to the actual situation, and the present invention is not limited to this.

Referring to fig. 3, in the present embodiment, the shafting structure 2 includes two sets of bearing outer rings 21, bearings 22 and bearing inner rings 23, which are matched with each other, and the elastic adjusting shims and the adjusting shims 3 are respectively disposed between the two bearing outer rings 21 and the housing 4.
