Description

Technical Field

[0001] The invention relates to an integrated torsional damping module, belonging to the technical field of structural vibration control. Background Art

[0002] The integrated torsional damping module is an innovative technology designed to improve the seismic / vibration reduction capabilities of structures, mechanical equipment, etc. through a modular design of additional damping.

[0003] In the prior art, many friction torsional dampers utilize a split design, assembled from multiple components. For example, some dampers include two fixed friction plates positioned opposite each other, with a rotatable friction plate positioned between them. These plates are connected by a specific connection structure and a pivot, forming a relatively rotatable assembly capable of generating frictional energy dissipation. This structure facilitates production, processing, installation, subsequent maintenance, and component replacement. Furthermore, to adapt to varying operating conditions and damping requirements, some friction torsional dampers feature adjustable features. For example, damping force can be adjusted by varying the contact pressure between the friction plates or by adjusting the number or thickness of the friction plates. Some dampers also incorporate special adjustment mechanisms, such as bolt adjustment mechanisms or spring preload adjustment mechanisms, to flexibly adjust damper performance parameters according to actual needs. Furthermore, the damper's internal structural design often incorporates specialized shapes and fittings to enhance friction and energy dissipation. For example, the friction plates of some dampers may feature concave and convex textures, grooves, and other structures to increase the coefficient of friction. Alternatively, specific arcs or wedges may be used at the interface between the friction plate and other components to ensure better fit and friction during rotation. Examples include CN110273956A, a torsional friction plate metal damper, and CN112081260A, a new steel bar rotary friction damper. Traditional damping devices are typically designed individually based on specific application requirements, resulting in diverse product designs, low yields, and difficulties in achieving prefabricated mass production and technical standardization. Summary of the Invention

[0004] To address the aforementioned shortcomings of the existing technology, the present invention proposes an integrated torsional damping module. This module utilizes an integrated modular design, integrating torsional damping functionality into a single, standardized module, improving production consistency and reliability. This module can be widely adapted to diverse application requirements, revolutionizing vibration control technology.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] An integrated torsional damping module comprises a housing, a pressurized closing plate, a spline transmission shaft, a friction plate, a wedge-shaped pre-load plate, a spline connection sleeve, and a flat key;

[0007] The spline connection sleeve is vertically inserted into the housing; a spline transmission shaft is inserted into the spline connection sleeve, and the two are fixed by a flat key; a friction plate is sleeved on the outer periphery of the spline connection sleeve; the wedge-shaped pre-load plate is pressed tightly between the friction plate and the housing; the pressure sealing plate is also provided on the top of the housing, and the bottom of the pressure sealing plate presses against the top of the wedge-shaped pre-load plate and applies pre-load to the wedge-shaped pre-load plate;

[0008] The wedge-shaped pre-loading plate is composed of two wedge-shaped pre-loading plates with interlocking inclined surfaces. The bottom of the pressurized sealing plate is pressed against one of the wedge-shaped pre-loading plates, and then the inclined surface squeezes the other wedge-shaped pre-loading plate, thereby converting the vertical downward pre-loading force into a horizontal squeezing force for squeezing the friction plate and generating friction damping energy dissipation between the friction plate and the wedge-shaped pre-loading plate.

[0009] The mechanical properties of the damping module can be adjusted by adjusting the preload torque of the pressurized closing plate, the angle of the wedge-shaped preload plate, and the material difference of the friction plate.

[0010] Furthermore, the pressurized closing plate is connected to the top of the shell by bolts and applies pre-pressure; a circular hole is reserved in the middle of the pressurized closing plate for passing the spline connecting sleeve.

[0011] Furthermore, the cross section of the pressurized sealing plate is an inverted L-shape, comprising a horizontal plate and a vertical plate, wherein the horizontal plate is bolted to the top of the shell, and the vertical plate is tightly pressed against one of the wedge-shaped pre-compression plates.

[0012] Furthermore, the friction plate and the spline connecting sleeve are fixed by bolts.

[0013] Furthermore, the bolt is a countersunk bolt.

[0014] Furthermore, a plurality of fixing holes are provided on the outer side of the shell for fixing and installing the damping module.

[0015] Furthermore, the shell is rectangular, and the number of the fixing holes is more than 3, which are arranged in a herringbone shape or a matrix on the outside of the shell.

[0016] Furthermore, the wedge-shaped pre-compression plates are arranged on both sides of the interior of the shell, and a plurality of bolts are arranged between the shell and the pressurized closing plate corresponding to each side.

[0017] Furthermore, the flat key is arranged at the bottom of the friction plate.

[0018] Furthermore, the bottom of the other wedge-shaped pre-compression plate abuts against the bottom plate of the shell.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention can realize mutual pin connection between modules through a spline transmission shaft and a spline connecting sleeve, and the mechanical performance of the device can be flexibly combined and adjusted from multiple dimensions such as the module's own performance, the number of modules and the module combination scheme.

[0021] The integrated torsional damping module of this invention features a Lego-like latch connection between its upper and lower parts. These modules can be prefabricated in batches at the factory, allowing for high-performance and customized damping and energy dissipation performance of the shock absorber by adjusting the number of modules. This effectively addresses the diverse and structurally diverse applications, while also significantly improving the performance, quality, and standardization of shock absorbers and related devices.

[0027] The following is combined with Figure 1-5 The present invention will be further described in detail with specific implementations to facilitate a clear understanding of the present invention, but they do not constitute a limitation to the present invention.

[0028] Example 1

[0029] As attached Figure 1-2 As shown, an integrated torsional damping module of this embodiment includes a housing 1, a pressurized sealing plate 2, bolts 3, a spline transmission shaft 4, a friction plate 5, a wedge-shaped pre-load plate 6, a spline connecting sleeve 7 and a flat key 8.

[0030] A splined connecting sleeve 7 extends vertically through the interior of the housing 1. A splined drive shaft 4 is threaded through the splined connecting sleeve 7, and the two are secured in place by a flat key 8. A friction plate 5 is sheathed around the outer periphery of the splined connecting sleeve 7, which is secured to the splined connecting sleeve 7 by countersunk bolts 3. A wedge-shaped preload plate 6 is pressed between the friction plate 5 and the housing 1. A pressure sealing plate 2 is also installed at the top of the housing 1. The bottom of the pressure sealing plate 2 presses against the top of the wedge-shaped preload plate 6, applying preload to the plate. A flat key 8 is located at the bottom of the friction plate 5.

[0031] like Figure 4 As shown, the wedge-shaped pre-stressing plate 6 is a pair of wedge-shaped pre-stressing plates arranged with two oblique surfaces interlocked. The bottom of the pressurized sealing plate 2 is pressed against one of the wedge-shaped pre-stressing plates 6, and then the other wedge-shaped pre-stressing plate 6 is squeezed through the oblique surface. The bottom of the other wedge-shaped pre-stressing plate 6 abuts against the bottom plate of the shell 1, thereby converting the vertical downward pre-stressing force into a horizontal extrusion force, which is used to squeeze the friction plate 5 and generate friction damping energy consumption between the friction plate 5 and the wedge-shaped pre-stressing plate 6.

[0032] Detailed, such as Figure 2-4 As shown, in this embodiment, a pressurized sealing plate 2 is connected to the top of the housing 1 via bolts 3, applying preload. A circular hole is reserved in the center of the pressurized sealing plate 2 for receiving a splined connection sleeve 7. The pressurized sealing plate 2 has an inverted L-shaped cross-section and comprises a horizontal plate and a vertical plate. The horizontal plate is connected to the top of the housing 1 via bolts 3, while the vertical plate presses against one of the wedge-shaped preload plates 6.

[0033] like Figure 3 As shown, the outer side of the housing 1 is provided with multiple fixing holes 9 for securing the damping module. In this embodiment, the housing 1 is rectangular, and there are three fixing holes 9 arranged in a herringbone pattern on the outer side of the housing 1. Wedge-shaped preload plates 6 are positioned on both sides of the interior of the housing 1, with three bolts 3 positioned between the housing 1 and the pressurized sealing plate 2 on each side.

[0034] In this embodiment, Figure 4-5 As shown, the torsion direction and pressure direction are displayed. By adjusting the preload torque of the pressurized sealing plate 2, the angle of the wedge-shaped preload plate 6 and the material difference of the friction plate 5, the mechanical properties of the damping module can be adjusted. θ , the friction force is f .

[0035] Example 2

[0036] In this embodiment, there are four fixing holes arranged in a four-point matrix around the shell 1, which is not shown in the figure. Other structures and connection methods are the same as those in Example 1 and will not be described in detail this time.

[0037] The above is merely a preferred embodiment of the present invention and does not constitute any formal limitation on the structure of the present invention. The layout and number of the present invention are not limited to this example and can be optimized according to actual engineering practices. Any modifications, equivalent changes, and decorations to the above embodiment based on the technical principles of the present invention that do not depart from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
