Description

Technical Field

[0001] The utility model relates to the technical field of brakes, and particularly relates to a brake device which realizes the braking purpose by the actuation between a brake expansion ring and a main shaft. Background Art

[0002] In the prior art, brake expansion ring devices are widely used in various machines and equipment to provide stable and reliable braking functions. However, there are still some obvious defects in these devices during actual application, especially the concentricity error problem during the assembly process.

[0003] During the assembly process of the existing brake expansion ring devices, due to the insufficient fitting accuracy between various components, concentricity errors often occur. This error causes the main shaft to be easily displaced under force during braking, thereby affecting the braking effect and the service life of the device. In addition, this concentricity error also increases the complexity of assembly. Usually, multiple assemblies and adjustments are required to meet the high concentricity requirements, which not only increases the production cost but also prolongs the production cycle. Due to the complex assembly process, the technical requirements for operators are relatively high, further increasing the production difficulty and cost.

[0004] In addition to the concentricity problem, the brake expansion ring devices in the prior art are prone to uneven wear during long-term use, resulting in a decrease in the durability and stability of the device. This increases the frequency of maintenance and replacement, thereby increasing the use cost. Difficult quality control is also a major problem in the prior art. Since it is difficult to completely avoid the concentricity error during the assembly process, it is difficult to ensure the quality consistency of the final product, which is particularly significant in large-scale production and affects the market competitiveness of the product.

[0005] Finally, most of the existing brake expansion ring devices are of split design, and the fit between various components needs to be repeatedly adjusted to meet the requirements, lacking the convenience and high precision brought by the integrated design. Due to these above-mentioned defects, there are many deficiencies in the existing brake expansion ring devices during actual application, and there is an urgent need for an improved brake device to solve the problems in the prior art.

As much as possible, in the drawings and the specification, the same reference numerals represent the same or similar components. In the drawings, for the sake of simplicity and convenience of marking, the shapes and thicknesses may be exaggerated.

[0037] Please refer to Figure 1 . Figure 1 It is a schematic diagram of the brake device according to the embodiment provided by the present utility model from the first perspective. According to an embodiment, Figure 1 is the brake device 100 in the state where the brake spindle is not installed, mainly composed of a housing 110 and a brake expansion ring assembly 120, and the center of the brake device 100 is a spindle accommodating portion 130 for installing the brake spindle.

[0038] Please also refer to Figures 1 to 3 . Figure 2 It is a schematic A - A sectional view of the brake device according to the embodiment provided by the present utility model; Figure 3 It is a partial sectional view of the housing and the brake expansion ring assembly of the brake device according to the embodiment provided by the present utility model. According to another embodiment, Figure 2 is the A - A section, showing the upper half of the brake device 100 in section, and Figure 3 is another partial sectional view provided for facilitating the illustration of the two corresponding first ends (1 st E) and the second ends (2 nd E) of the housing 110. As Figures 1 to 3 can be seen, the brake device 100 includes a housing 110 and a brake expansion ring assembly 120. The brake expansion ring assembly 120 is disposed inside the housing 110, and the center of the brake expansion ring assembly 120 has a spindle accommodating portion 130, and the spindle accommodating portion 130 penetrates through the first end (1 st E) and the second end (2 nd E) of the housing for configuring the brake spindle. And the brake expansion ring assembly includes an expansion ring 121, a gasket 122, and a plurality of first bearings 123. The expansion ring 121 is disposed on the inner side surface of the housing 110 and is adjacent to the first end (1st E). The gasket 122 is disposed on the inner side surface of the expansion ring 121. A plurality of first bearings 123 are disposed on the inner side surface of the gasket 122.

[0039] As Figures 2 to 3 , according to another embodiment, the housing 110 is of an annular structure, and the expansion ring 121 is annularly disposed on the inner side surface of the housing 110. In addition, the gasket 122 may also be of an annular structure, and the gasket 122 may also be annularly disposed on the inner side surface of the expansion ring 121.

[0040] Furthermore, an interference fit is provided between the expansion ring 121 and the gasket 122. Specifically, it may be as Figures 2 to 3 shown, the annular expansion ring 121 and the gasket 122 are in an interference fit. However, this embodiment is only illustrative of the mating state of the annular expansion ring 121 and the gasket 122.

[0041] An interference fit is achieved by designing the dimensions of two mating parts to be squeezed against each other during assembly, creating a certain interference between them, thereby achieving a tight fit. Specifically, the outer diameter of one of the mating parts is slightly larger than the inner diameter of the other part, such that an external force needs to be applied for pressing or expanding during assembly. In the present utility model, an interference fit is provided between the expansion ring 121 and the gasket 122, which is beneficial for improving the concentric geometric accuracy.

[0042] In addition, in actual situations, the expansion ring 121 and the gasket 122 may also be composed of non-annular structures or other geometric structures, and then an interference fit configuration is carried out.

[0043] As Figures 1 to 5 , Figure 5 is a schematic view of a braking device for installing a brake spindle according to an embodiment provided by the present utility model. According to another embodiment, each of the first bearings 123 is annularly disposed on the inner side surface of the gasket 122. The purpose of disposing the first bearings 123 on the inner side surface of the gasket 122 in this embodiment is to further improve the concentric geometric accuracy between the components inside the brake expansion ring assembly 120. And the annular configuration helps to evenly distribute the load, further improving the concentricity of the entire body and reducing the concentricity error during operation.

[0044] According to still another embodiment, the surface of the gasket 122 facing the first end (1 st E) is connected to the expansion ring 121, and the surface of the gasket 122 facing the second end (2 nd E) is provided with a plurality of second bearings 124. Further, each of the second bearings 124 is annularly disposed on the surface of the gasket 122 facing the second end (2 nd E).

[0045] Furthermore, the first bearing 123 and / or the second bearing 124 can be elongated bearings, which can provide a larger contact area and support region, helping to disperse stress and enhance structural stability. Also, the larger contact area enables the bearings to more effectively support the brake spindle 200, reducing deflection and displacement. Moreover, due to the elongated bearings providing a longer support surface, the contact between the bearings and the brake spindle 200 is smoother, thereby reducing friction and wear. Therefore, the annularly arranged elongated bearings (the first bearing 123 and the second bearing 124) can not only significantly improve the concentricity and stability of the braking device 100, but also reduce friction and wear, enhance the running smoothness and load-bearing capacity, while simplifying the maintenance process and comprehensively improving the performance and durability of the braking device 100.

[0046] In summary, as in the multiple embodiments provided by the present utility model, the interference fit between the expansion ring 121 and the gasket 122, combined with the annular arrangement of the first bearing 123 and the second bearing 124, significantly improves the concentricity and stability of the braking device 100. Among them, the interference fit ensures a tight connection between the expansion ring 121 and the gasket 122, reducing assembly errors. And the annularly arranged elongated bearings (the first bearing 123 and the second bearing 124) provide a larger contact area and support region to disperse stress and reduce friction and wear.

[0047] The above is only an example to illustrate the preferred embodiments of the present utility model, and is not intended to limit the scope of implementation. Any simple substitution and equivalent change made according to the scope of the patent application of the present utility model and the content of the patent specification shall fall within the scope of the patent application of the present utility model.
