Description

Technical Field

[0001] This utility model belongs to the technical field of heat-resistant composite collars, and relates to a heat-dissipating heat-resistant composite collar. Background Technology

[0002] The main drawbacks of existing heat-resistant composite collars in terms of stable heat resistance lie in the mismatch of their thermal expansion coefficients, insufficient thermal stability, and decreased mechanical properties at high temperatures. Composite collars are typically composed of multiple materials such as ceramic fibers and resin matrices. The significant differences in thermal expansion coefficients among these materials can easily lead to internal stress at high temperatures, resulting in unstable material properties. Conventional solutions include selecting materials with similar thermal expansion coefficients for composite formation, optimizing the composite material ratio and structural design, and employing surface coating technology to improve heat resistance. However, these methods also have drawbacks. For example, selecting materials with similar thermal expansion coefficients may limit the range of material choices, leading to increased costs or compromises in performance. Therefore, a heat-resistant composite collar with heat dissipation capabilities is urgently needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat-dissipating and heat-resistant composite collar to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a heat-dissipating and heat-resistant composite collar, comprising: an outer collar and an inner core collar, wherein the inner side of the outer collar is provided with a set of middle collars for enhancing the strength of the outer collar, and the inner side of the middle collar is provided with a set of inner collars for supporting the inner side of the middle collar, and the inner side of the outer collar and the inner side of the middle collar are respectively provided with threaded grooves of the same structure.

[0005] Both the outer side of the middle collar and the outer side of the inner collar are provided with external threads of the same structure. The outer collar includes an outer heat-resistant layer and an inner connecting thread groove. The inner side of the outer heat-resistant layer is provided with an outer ceramic heat-insulating layer for improving the external heat resistance effect. The inner side of the outer ceramic heat-insulating layer is provided with an inner heat-insulating lining for preventing the mixing of internal and external high temperatures. The inner side of the inner heat-insulating lining is provided with an inner ceramic heat-insulating layer for improving the internal heat resistance effect.

[0006] In a preferred embodiment, the inner ceramic heat-insulating layer and the outer ceramic heat-insulating layer have the same specifications, and the internal ceramic structure composition and thickness of the inner and outer ceramic heat-insulating layers are the same. The outer ceramic heat-insulating layer and the outer heat-resistant layer are bonded together. When the composite collar is used by the operator in a high-temperature environment, the outer heat-resistant layer and the inner heat-resistant layer can provide heat resistance to the inner and outer sides of the outer collar, the middle collar, and the inner collar. At the same time, while providing heat resistance, the outer ceramic heat-insulating layer and the inner ceramic heat-insulating layer can provide higher heat resistance to the outer heat-resistant layer and the inner heat-resistant layer, respectively, to ensure that the outer collar, the middle collar, and the inner collar can be used stably in a high-temperature environment.

[0007] In a preferred embodiment, the inner ceramic heat-insulating layer is bonded to the inner heat-resistant layer, and both the inner heat-resistant layer and the outer heat-resistant layer are made of a titanium alloy material. The inner side of the inner ring is provided with a set of inner expansion sleeves for mutual expansion and engagement with the inner side of the inner ring.

[0008] In a preferred embodiment, the inner retaining sleeve has several sets of tension bars evenly distributed for natural expansion, and the lower end of the inner retaining sleeve is provided with a set of inner core sleeves for fitting and limiting the bearing housing.

[0009] In a preferred embodiment, the inner core sleeve and the inner retaining sleeve are an integral structure. The outer side of the inner core sleeve is provided with a set of inner rolling grooves for limiting and fitting with the internal balls of the bearing housing. The inner core sleeve and the bearing housing are movably fitted and connected.

[0010] In a preferred embodiment, the lower end of the bearing housing is provided with a set of mounting bases for limiting its installation, and the front side of the outer ring is provided with a set of inner locking bolts for locking its interior. The inside of the outer ring is provided with a set of fixing holes for locking and limiting the outer ring. When the operator needs to separate the outer ring, middle ring and inner ring, the operator can remove the inner locking bolts from the fixing holes to release the outer ring from the locking state, thereby facilitating the operator to quickly remove, maintain and disassemble the outer ring, middle ring and inner ring.

[0011] In a preferred embodiment, the outer ring, middle ring, and inner ring have the same internal structure, and the inner diameters of the outer ring, middle ring, and inner ring in plan view decrease proportionally.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: when the staff uses the composite collar in a high-temperature environment, its outer heat-resistant layer and inner heat-resistant layer can provide heat resistance to the outer collar, middle collar and inner collar on both sides. At the same time, while the outer heat-resistant layer and inner heat-resistant layer provide heat resistance, their outer ceramic heat-insulating layer and inner ceramic heat-insulating layer can provide higher heat resistance to the outer heat-resistant layer and inner heat-resistant layer respectively, so as to ensure that the outer collar, middle collar and inner collar can be used stably in a high-temperature environment.

[0013] When workers need to separate the outer ring, middle ring, and inner ring, they can remove the inner locking bolt from the fixing hole to release the outer ring from its locked state, thus facilitating the quick removal, maintenance, and disassembly of the outer ring, middle ring, and inner ring.

At the same time, while the outer heat-resistant layer 10a and the inner heat-resistant layer 10e provide heat resistance, the outer ceramic heat-insulating layer 10b and the inner ceramic heat-insulating layer 10d can provide higher heat resistance to the outer heat-resistant layer 10a and the inner heat-resistant layer 10e respectively, so as to ensure that the outer collar 100, the middle collar 110 and the inner collar 120 can be used stably in a high-temperature environment.

[0025] The inner ceramic heat-insulating layer 10d is bonded to the inner heat-resistant layer 10e. Both the inner heat-resistant layer 10e and the outer heat-resistant layer 10a are made of a titanium alloy material. The inner sleeve 120 has a set of inner expansion sleeves 130 for expanding and engaging with the inner side of the inner sleeve 120.
