Description

Technical Field

[0001] The utility model relates to the technical fields of mechanical engineering and bearing assembly technology, and particularly relates to an eccentric tooling for assembling a double-row swing rod bearing. Background Art

[0002] For traditional single-row swing rod bearings, their rolling elements are designed in a single row. Such bearings generally consist of an inner ring, an outer ring, single-row rolling elements and a cage. The single-row rolling elements are evenly distributed between the inner ring and the outer ring through the cage, and their shape, size and quantity directly affect the service performance and life of the bearing.

[0003] With the continuous development of industrial technology, the requirements for the performance of mechanical equipment are getting higher and higher. Traditional single-row bearings have been difficult to meet the usage requirements under certain special working conditions. Single-row bearings can only bear axial loads in one direction. When bearing radial loads, additional axial forces will be caused, restricting their applications in high-load and complex stress environments; when single-row bearings bear overturning moments or large torques, their rigidity and stability are poor, which may lead to a decline in the performance of the mechanical system.

[0004] Therefore, it is necessary to design a double-row swing rod bearing, which emerges as a new type of bearing. It combines the advantages of double-row bearings and swing rod systems, and has higher load-bearing capacity and better motion control performance. Summary of the Utility Model

The terms "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, rather than indicating or implying that a double-row swing rod bearing assembly eccentric tooling or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. It is only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model. In order to make the objectives, features and advantages of the present utility model more obvious and understandable, please refer to the accompanying drawings.

[0025] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical substance significance. Any modification of the structure, change of the ratio relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the objectives that can be achieved, should still fall within the scope that the technical content disclosed by the present utility model can cover.

[0026] The following describes the specific structure of a double-row swing rod bearing assembly eccentric tooling:

[0027] Please refer to Figure 1 , the double-row swing rod bearing assembly eccentric tooling of this embodiment includes an inner ring 1, an outer ring 2 and rolling elements 3. The rolling elements 3 are arranged in a raceway formed between the inner ring 1 and the outer ring 2, and the inner ring 1 can rotate and adjust relative to the outer ring 2 through the rolling elements 3.

[0028] Please continue to refer to Figure 2 and Figure 3 Furthermore, the eccentric tooling further includes an eccentric component 4, and the eccentric component 4 is fitted to the above-mentioned inner ring 1 and the above-mentioned outer ring 2. The eccentric component 4 includes a base 401, and the base 401 has a first surface 4011. The first surface 4011 is inclined with respect to a first direction to adapt to the tooling. Preferably, in this embodiment, the first direction is the direction parallel to the horizontal ground. The eccentric component 4 includes a positioning seat 402, and the positioning seat 402 has a second surface 4021. The second surface 4021 is inclined with respect to the first direction and is fitted to the first surface 4011, such that the first surface 4011 and the second surface 4021 are in abutment.

[0029] Furthermore, the base 401 is provided with a first recess 4012, and a first hole 4013 is opened in the first recess 4012. The positioning seat 402 is provided with a second recess 4022, and a second hole 4023 is provided in the second recess 4022. The first hole 4013 communicates with the second hole 4023.

[0030] Furthermore, the eccentric component 4 includes a connecting member 403. One end of the connecting member 403 is disposed in the first recess 4012, and the other end of the connecting member 403 is disposed in the second recess 4022. The connecting member 403 is also fitted to the first hole 4013 and the second hole 4023. A part of the inner ring 1 is disposed in the second recess 4022 and is connected to the connecting member 403. The movement of the inner ring 1 is restricted by the connecting member 403 passing through the first hole 4013 and the second hole 4023.

[0031] Please continue to refer to Figure 4 and Figure 5 Furthermore, the eccentric component 4 further includes an eccentric die 404, and the eccentric die 404 is disposed between the positioning seat 402 and the outer ring 2. A third hole 4041 is opened on the surface of the eccentric die 404, and the center of the orifice on both sides of the eccentric die 404 is eccentrically disposed. The rolling elements 3 are placed from the side with a larger eccentricity. By pushing the outer ring 2 to abut one end of the third hole 4041, the gap between the outer ring 2 and the other end of the third hole 4041 reaches the maximum, and the rolling elements 3 can be placed. After the placement is completed, the outer ring 2 is pushed again to restore its center, and thus the assembly of the rolling elements 3 between the inner ring 1 and the outer ring 2 can be completed.

[0032] Further, the eccentric tooling further includes a positioning member 5, which is fitted to the rolling elements 3 and disposed within the inner ring 1. By providing the positioning member 5, the rolling elements 3 are formed into a double row. The positioning member 5 has an arc-symmetric structure and the end face area decreases from the middle to both ends, which facilitates taking out from the inner ring 1 and assembling the rolling elements 3 at the same time.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
