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 torsion dampers adopt a split design and are assembled from multiple parts. For example, some dampers include fixed friction plates arranged relatively to each other, with a rotatable friction plate arranged in the middle, which are connected by a specific connection structure and a pivot to form a combination that can rotate relatively and generate friction energy consumption. This structure is convenient for production, processing, installation, and later maintenance and replacement of parts. In addition, in order to adapt to different working conditions and damping requirements, some friction torsion dampers have adjustable structures. For example, the damping force can be adjusted by changing the contact pressure between the friction plates, adjusting the number or thickness of the friction plates, etc. Some dampers are also equipped with special adjustment devices, such as bolt adjustment mechanisms, spring preload adjustment mechanisms, etc., which can flexibly change the performance parameters of the damper according to actual needs. In addition, in the internal structure design of the damper, some special shapes and matching structures are used to improve the friction effect and energy consumption capacity. For example, the friction plate surface of some dampers may be designed with concave-convex textures, grooves and other structures to increase the friction coefficient; or specific arcs, wedges and other shapes are used at the joints between the friction plate and other components to enable the friction plate to fit and rub better during rotation. For example, CN110273956A is a torsional friction plate type metal damper, CN112081260A is a new type of steel bar rotation friction damper, etc. That is, traditional damping devices are usually independently designed according to specific application requirements, but this leads to diversified product design solutions, low yield, and difficulty in achieving prefabricated mass production and technical standardization. Summary of the invention

[0004] In view of the above-mentioned defects in the prior art, the present invention proposes an integrated torsional damping module. It adopts an integrated modular design to integrate the torsional damping function into a standard module, thereby improving the consistency and reliability of production. This module can be widely applied to different application requirements and brings innovation to vibration control technology.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: 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; The spline connection sleeve is vertically inserted into the shell; a spline transmission shaft is inserted into the spline connection sleeve, and the two are fixed by a flat key limiter; a friction plate is sleeved on the outer periphery of the spline connection sleeve; the wedge-shaped pre-compression plate is pressed tightly between the friction plate and the shell; the pressurized sealing plate is also arranged on the top of the shell, and the bottom of the pressurized sealing plate presses against the top of the wedge-shaped pre-compression plate and applies pre-compression to the wedge-shaped pre-compression plate; The wedge-shaped pre-compression plate is a wedge-shaped pre-compression plate with two inclined surfaces buckled together, and the bottom of the pressurized sealing plate is pressed against one of the wedge-shaped pre-compression plates, and then the other wedge-shaped pre-compression plate is pressed through the inclined surface, so that the vertical downward pre-compression force is converted into a horizontal extrusion force for pressing the friction plate, and friction damping energy consumption is generated between the friction plate and the wedge-shaped pre-compression plate; 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.

[0006] Furthermore, the pressurized closing plate is connected to the top of the shell by bolts and a pre-pressure is applied; a circular hole is reserved in the middle of the pressurized closing plate for passing the spline connecting sleeve.

[0007] 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 pressed against one of the wedge-shaped pre-compression plates.

[0008] Furthermore, the friction plate and the spline connecting sleeve are fixed by bolt connection.

[0009] Furthermore, the bolt is a countersunk bolt.

[0010] Furthermore, a plurality of fixing holes are provided on the outer side of the shell for fixing and installing the damping module.

[0011] 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 outer side of the shell.

[0012] 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.

[0013] Furthermore, the flat key is arranged at the bottom of the friction plate.

[0014] Furthermore, the bottom of the other wedge-shaped pre-compression plate abuts against the bottom plate of the shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention can realize mutual latch 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.

[0016] The upper and lower parts of the integrated torsion damping module of the present invention can realize a "Lego"-like bolt connection, and the integrated torsion damping module can be prefabricated in batches in the factory. By adjusting the number of integrated torsion damping modules, the high performance and customization of the damping energy dissipation performance of the shock absorbing device can be achieved. It can effectively cope with the diversification and structural differentiation of the working objects, and at the same time effectively improve the product performance quality and standardization process of the shock absorbing products or related application devices.

A friction plate 5 is sleeved on the outer periphery of the spline connection sleeve 7, and the friction plate 5 and the spline connection sleeve 7 are connected and fixed by a countersunk bolt 3. A wedge-shaped pre-compression plate 6 is pressed between the friction plate 5 and the housing 1. A pressurized sealing plate 2 is also provided on the top of the housing 1, and the bottom of the pressurized sealing plate 2 presses against the top of the wedge-shaped pre-compression plate 6 and applies pre-compression to the wedge-shaped pre-compression plate 6.

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 inclined surface. The bottom of the other wedge-shaped pre-stressing plate 6 abuts against the bottom plate of the outer shell 1, thereby converting the vertical downward pre-stressing force into a horizontal squeezing force, which is used to squeeze the friction plate 5 and generate friction damping energy dissipation between the friction plate 5 and the wedge-shaped pre-stressing plate 6. Detailed, such as Figure 2-4 As shown, in this embodiment, the pressurized sealing plate 2 is connected to the top of the housing 1 by bolts 3, and a pre-pressure is applied. A circular hole is reserved in the middle of the pressurized sealing plate 2 for passing a spline connection sleeve 7. The cross section of the pressurized sealing plate 2 is an inverted L-shape, including a horizontal plate and a vertical plate. The horizontal plate is connected to the top of the housing 1 by bolts 3, and the vertical plate is pressed against one of the wedge-shaped pre-pressure plates 6.

[0022] like Figure 3 As shown, the outer side of the housing 1 is provided with a plurality of fixing holes 9 for fixing and installing the damping module. In this embodiment, the housing 1 is rectangular, and there are three fixing holes 9 arranged in a herringbone shape on the outer side of the housing 1. Wedge-shaped pre-compression plates 6 are arranged on both sides of the interior of the housing 1, and three bolts 3 are arranged between the housing 1 and the pressurized closing plate 2 on each side.

[0023] In this embodiment, Figure 4-5 As shown, the torsion direction and pressure direction are shown. 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 .

[0024] Example 2 In this embodiment, there are four fixing holes arranged in a four-point matrix around the housing 1, which is not shown in the figure. Other structures and connection methods are the same as those in Embodiment 1 and will not be described in detail this time.
