Description

Technical Field

[0001] This utility model relates to the field of disc spring technology, and in particular to a high-temperature resistant disc spring. Background Technology

[0002] Disc springs, also known as Belleville spring washers, were invented by the Frenchman Belleville. They are conical discs that can be used individually or in series or parallel. They bear static or dynamic loads along the axial direction at the upper inner edge and lower outer edge. When compressed, they deform until they are flattened, storing energy as a live load.

[0003] Chinese Patent Publication No. CN219197974U discloses a high-temperature resistant disc spring, including a disc spring body and a central base layer. The top and bottom surfaces of the base layer are covered with heat-insulating layers, and the outer sides of the heat-insulating layers are covered with corrosion-resistant layers. The outer sides of the corrosion-resistant layers are covered with high-temperature resistant layers. A first rubber sealing ring is installed on the inner side of the upper end of the disc spring body, and a second rubber gasket is installed on the bottom end of the disc spring body. This invention, by forming different protective layers on the outer side of the base layer in the disc spring body, with the high-temperature resistant layer protecting the base layer in the middle, can prevent high temperatures from affecting the base layer and causing deformation of the disc spring body. The heat-insulating layer can initially isolate the heat from the outside, preventing heat from directly affecting the internal structure.

[0004] Existing high-temperature disc springs are often used in series or parallel. When multiple series or parallel disc springs are used under load, the disc springs slip, causing friction between the series or parallel high-temperature disc springs, resulting in surface damage and reducing the service life of the high-temperature disc springs. Utility Model Content

[0005] To address the problems existing in the background technology, a high-temperature resistant disc spring is proposed.

[0006] This utility model proposes a high-temperature resistant disc spring, comprising: a housing, a guide seat, and a guide spindle;

[0007] The housing is equipped with a slider and has a hollow interior housing a disc spring body, which is connected to functional components.

[0008] The guide seat is installed at the bottom of the housing;

[0009] And the guide spindle is mounted on the guide seat.

[0010] Preferably, the housing, the disc spring body, and the functional components constitute a high-temperature resistant disc spring structure;

[0011] Both the housing and the disc spring body are provided with through holes a, which are used to connect with the guide spindle.

[0012] Preferably, the functional component includes a high-temperature resistant layer mounted on the disc spring body, the high-temperature resistant layer being fitted with a heat insulation layer, the heat insulation layer being fitted with a corrosion-resistant layer, and the corrosion-resistant layer being fitted with a base layer.

[0013] Preferably, the guide seat is provided with a through hole b, through which a connecting bolt passes, for detachably connecting the guide seat and the guide spindle.

[0014] Preferably, the guide seat and the guide spindle are detachably connected to the high-temperature resistant disc spring structure.

[0015] Preferably, two arc-shaped blocks are installed around the guide mandrel, and the distance between the two ends of the arc-shaped blocks forms a guide cavity; a guide sleeve is installed above the guide mandrel;

[0016] The guide sleeve and guide seat are opposite each other and are used to limit the upper and lower positions of the high-temperature resistant disc spring structure.

[0017] Preferably, the inner wall of the guide cavity is connected to a slider, which is used to cooperate with the series or parallel high-temperature resistant disc spring structure to slide under load.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] This invention utilizes a sliding block to synchronously connect multiple high-temperature resistant disc springs in series or parallel. Under load, the disc springs slide along the guide cavity, preventing surface damage caused by friction between them and extending their service life. Furthermore, the disc spring body is mounted on the inner wall of the housing, which uses fiber-reinforced material as the base material for friction, providing anti-friction properties. This increases the impact strength, bending strength, and compressive strength of the high-temperature resistant disc spring, improving its practicality. Attached Figure Description

[0024] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0025] Example 1

[0026] like Figure 1-Figure 3 As shown, this utility model proposes a high-temperature resistant disc spring, comprising: a housing 1, a guide seat 2, and a guide spindle 3; the housing 1 is fitted with a slider 101 and has a hollow interior for mounting a disc spring body 102, the disc spring body 102 being connected to functional components; the guide seat 2 is mounted below the housing 1; and the guide spindle 3 is mounted on the guide seat 2. By using fiber-reinforced material as the base material for the friction material in the housing 1, it facilitates anti-friction performance, thereby increasing the impact strength, bending strength, and compressive strength of the high-temperature resistant disc spring, thus improving its practicality.

[0027] To further explain, the housing 1, the disc spring body 102, and the functional components constitute a high-temperature resistant disc spring structure. Both the housing 1 and the disc spring body 102 are provided with through holes a for connection with the guide spindle 3. Through holes a, it is easy to install the high-temperature resistant disc spring structure with the guide spindle 3 and the guide seat 2, allowing multiple high-temperature resistant disc spring structures to be connected in series or parallel for convenient use of the components.

[0028] To further explain, two arc-shaped blocks 301 are installed around the guide spindle 3, and the distance between the two ends of the arc-shaped blocks 301 forms a guide cavity; a guide sleeve 302 is installed above the guide spindle 3; the guide sleeve 302 and the guide seat 2 are opposite each other and are used to limit the upper and lower positions of the high-temperature resistant disc spring structure. By installing multiple units in series or parallel, the guide sleeve 302 is connected to the uppermost high-temperature resistant disc spring structure, and the guide seat 2 is connected to the lowermost high-temperature resistant disc spring structure, which avoids the displacement or falling off of multiple series or parallel high-temperature resistant disc springs during use, thus improving the performance of the high-temperature resistant disc springs.

[0029] To further explain, a slider 101 is connected to the inner wall of the guide cavity, which is used to cooperate with the series or parallel high-temperature resistant disc spring structure to slide under load. By synchronously sliding the series or parallel high-temperature resistant disc spring structure under load through the slider 101, the slider 101 moves along the guide cavity, which facilitates smoother sliding of the series or parallel high-temperature resistant disc spring structure under load.

[0030] Example 2

[0031] like Figure 1 and Figure 2As shown, this utility model proposes a high-temperature resistant disc spring. Based on the above embodiments, this embodiment also details the specific components of the functional parts and the guide seat 2, as well as their cooperation methods.

[0032] Further explanation: The functional components include a high-temperature resistant layer 103 mounted on the disc spring body 102, a heat insulation layer 104 mounted on the high-temperature resistant layer 103, a corrosion-resistant layer 105 mounted on the heat insulation layer 104, and a base layer 106 mounted on the corrosion-resistant layer 105. By using a tungsten alloy for the high-temperature resistant layer 103 and a high-carbon steel for the base layer 106, the high-temperature resistant layer 103 protects the base layer 106 in the middle, preventing high temperatures from affecting the base layer 106 and causing deformation of the disc spring body 102. The heat insulation layer 104 initially isolates external heat, preventing heat from directly affecting the internal structure. Furthermore, the corrosion-resistant layer 105 improves the overall service life, enhances the stability and durability of the internal structure of the high-temperature disc spring body 102, and improves the practicality of the high-temperature disc spring.

[0033] To further explain, the guide seat 2 is provided with a through hole b through which a connecting bolt passes, for detachably connecting the guide seat 2 and the guide spindle 3. The through hole b extends to both the upper and lower sides of the guide seat 2, allowing the bolt to be rotatably connected to the bottom hole of the guide spindle 3 via the threaded connection of the through hole b, facilitating the connection and use of the guide seat 2 and the guide spindle 3.

[0034] To further explain, the guide seat 2 and the guide spindle 3 are detachably connected to the high-temperature resistant disc spring structure. The guide seat 2 and the guide spindle 3 are combined to meet the usage requirements of the high-temperature resistant disc spring structure, thereby increasing its practicality.

[0035] The working principle of this utility model is as follows: First, the housing 1 is fitted into the outer periphery of the guide spindle 3 through the through hole. The housing 1 and the temperature disc spring body 102 are installed. Functional components are installed inside the temperature disc spring, so that the housing 1, the temperature disc spring body 102 and the functional components constitute a high-temperature resistant temperature disc spring structure. Then, according to the series or parallel connection requirements, the high-temperature resistant temperature disc spring structure is gradually connected to the guide spindle 3. Then, the guide seat 2 and the guide spindle 3 are installed with bolts, so that the high-temperature resistant temperature disc spring structure can be used in series or parallel.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
