Description

Technical Field

[0001] This utility model relates to the technical field of compressor hemispherical assembly, specifically a compressor hemispherical assembly with an elastic pre-tightening unit. Background Technology

[0002] The hemispherical assembly of a compressor typically refers to the component used to seal, support, and secure the internal moving parts of the compressor. This component is generally used in reciprocating compressors, serving a load-bearing function to ensure that the various moving parts of the compressor operate smoothly and without obstruction. In automotive air conditioning compressors, the hemispherical assembly refers to the component installed between the cylinder and the piston swashplate, and its diameter and height require very high precision.

[0003] In existing compressor hemispherical assemblies, the installation of the hemispherical assembly needs to be adjusted according to the distance between the cylinder and the piston swashplate during actual operation. This can easily create gaps, making it difficult to quickly form a sealed compression chamber and ensuring that the compressor can operate more stably. Furthermore, most hemispherical assemblies are one-piece and do not have good wear resistance and impact resistance. They are prone to vibration during cylinder operation, which can cause the hemispherical assembly to shift and fail to provide stable preload at high temperatures.

[0004] Therefore, a compressor hemispherical assembly with an elastic preload unit is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a compressor hemispherical assembly with an elastic preload unit. This solves the problem that in actual operation, the compressor hemispherical assembly needs to be adjusted and installed according to the distance between the cylinder and the piston swashplate, which easily leads to gaps, makes it difficult to quickly form a sealed compression chamber, and cannot guarantee more stable normal operation of the compressor. Furthermore, most hemispherical assemblies are one-piece, lacking good wear resistance and impact resistance, and are prone to vibration during cylinder operation, causing the hemispherical assembly to easily shift and failing to provide stable preload force at high temperatures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hemispherical component body is included, a fixing cavity is fixedly connected inside the hemispherical component body, a spring is fixedly connected inside the fixing cavity, a rubber ring is fixedly connected to the bottom end of the spring, and a sealing ring is provided inside the rubber ring.

[0007] Preferably, an elastic sheet is fixedly connected to the lower surface of the rubber ring. The elastic sheet is used to maintain the stability of the contact force of the hemispherical assembly body and prevent loosening caused by changes in temperature, pressure or load.

[0008] Preferably, the elastic sheet is provided with a shock-absorbing material inside, which has high wear resistance, good elasticity and impact resistance.

[0009] Preferably, the elastic sheet is provided with a sealing material inside, which has good self-lubricating properties and elasticity, so that the elastic sheet can provide a stable preload at high temperatures.

[0010] Preferably, the interior of the elastic sheet is provided with an anti-corrosion material, which has good chemical stability, high temperature resistance and elasticity.

[0011] Preferably, the spring is a steel structure, does not have high elasticity, and is confined only to the inside of the fixed cavity.

[0012] Preferably, the upper surface of the rubber ring abuts against the lower surface of the hemispherical assembly body.

[0013] Compared with the prior art, this utility model provides a compressor hemispherical assembly with an elastic preload unit, which has the following advantages:

[0014] 1. By installing a spring inside the fixed cavity, the rubber ring is pressed between the cylinder and the piston swashplate by the action of the spring when the compressor is working. By sealing the gap between the cylinder and the piston swashplate, a sealed compression cavity is formed, which enables the compressor to work more stably.

[0015] 2. By incorporating elastic sheets, the hemispherical assembly body exhibits high wear resistance, good elasticity and impact resistance, as well as good chemical stability during use. It also possesses good self-lubricating properties and elasticity, providing stable preload at high temperatures. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1 - Figure 4 In this embodiment, a compressor hemispherical assembly with an elastic pre-tightening unit includes a hemispherical assembly body 1. A fixed cavity 2 is fixedly connected inside the hemispherical assembly body 1. A spring 3 is fixedly connected inside the fixed cavity 2. A rubber ring 4 is fixedly connected to the bottom end of the spring 3. A sealing ring 5 is provided inside the rubber ring 4. The spring 3 is a steel structure and does not have high elasticity, which is limited to the inside of the fixed cavity 2.

[0024] The fixed cavity 2 is fixed inside the hemispherical assembly body 1, which fixes the internal spring 3. Under the action of the spring 3, the rubber ring 4 can drive the sealing ring 5 to squeeze between the cylinder and the piston swashplate when the compressor is working, so that the gap between the two is filled and the gap between the cylinder and the piston swashplate is sealed, thereby forming a sealed compression cavity, so that the compressor can work more stably.

[0025] An elastic sheet 6 is fixedly connected to the lower surface of the rubber ring 4. The elastic sheet 6 is used to maintain the stability of the contact force of the hemispherical component body 1 and avoid loosening due to changes in temperature, pressure or load. The elastic sheet 6 is provided with a shock-absorbing material 7, which has high wear resistance, good elasticity and impact resistance. The elastic sheet 6 is provided with a sealing material 8, which has good self-lubricating properties and elasticity and can provide stable pre-tightening force at high temperature. The elastic sheet 6 is provided with an anti-corrosion material 9, which has good chemical stability, high temperature resistance and elasticity. The upper surface of the rubber ring 4 abuts against the lower surface of the hemispherical component body 1.

[0026] Among them, the elastic sheet 6 absorbs the vibration or impact generated by the cylinder or compressor, reducing the noise and wear of the mechanical system. During long-term use, the elastic sheet 6, together with the hemispherical assembly body 1, can maintain the stability of the contact force and avoid loosening caused by changes in temperature, pressure or load. The shock-absorbing material 7 inside the elastic sheet 6 can be made of polyurethane, which can provide elasticity and impact resistance to the hemispherical assembly body 1 and prevent damage to the hemispherical assembly body 1 in the gap between the cylinder and the piston swashplate. The sealing material 8 can be made of graphite, which can provide stable preload even at high temperatures. Combined with the use of the spring 3, it achieves self-lubricating performance and elasticity, enabling the gap to be quickly sealed. The anti-corrosion material 9 can be made of fluororubber, which enables the hemispherical assembly body 1 to achieve high temperature resistance and chemical corrosion resistance in a sealed environment, extending the service life of the hemispherical assembly body 1.

[0027] In the above embodiments, the hemispherical assembly body 1 serves to seal and protect, ensuring that the compression process inside the compressor is not affected by external factors, and preventing refrigerant leakage. Since the compressor is subjected to large pressure and vibration during operation, the hemispherical assembly body 1 is designed to be very robust, which helps to withstand these forces and maintain the stability of the overall structure. At the same time, the compressor generates heat during operation, and the elastic sheet 6 in the hemispherical assembly body 1 plays a certain role in heat dissipation and heat resistance. In addition, the outer shell of the hemispherical assembly body 1 in the prior art sometimes also has a heat dissipation effect, which helps to reduce overheating problems.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
