Description

Technical Field

[0001] This utility model belongs to the field of support ring technology, specifically a composite structure of compressor support ring with self-compensation function. Background Technology

[0002] The compressor support ring prevents the compressor piston from directly contacting and rubbing against the cylinder during operation, thus protecting the cylinder and piston from damage. However, the support ring operates under the high-temperature friction environment of the compressor for extended periods, making it highly susceptible to thermal deformation and breakage. This is especially true when the support ring is poorly lubricated, leading to excessive heat and wear. Therefore, this application proposes a composite structure for the compressor support ring with self-compensation to improve upon existing support rings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 4 The present invention discloses a compressor support ring composite structure with self-compensation function, comprising a support ring body 1, a plurality of combined grooves 2 formed on the arc-shaped outer surface of the support ring body 1, a plurality of oil inlet holes 3 formed inside the combined grooves 2, a plurality of micro through holes 4 formed at the top of the arc-shaped outer surface of the support ring body 1, a plurality of micro through holes 5 formed at the middle position of the arc-shaped outer surface of the support ring body 1, a plurality of micro through holes 6 formed at the bottom of the arc-shaped outer surface of the support ring body 1, and an annular inner cavity 7 formed inside the support ring body 1, the annular inner cavity 7 being connected to the oil inlet holes 3, micro through holes 4, micro through holes 5 and micro through holes 6;

[0023] During the up-and-down movement of the support ring body 1 following the piston, the lubricating oil inside the cylinder body will enter the interior of the combined groove 2. Some of the lubricating oil will enter the interior of the annular inner chamber 7 through the oil inlet 3, and the annular inner chamber 7 will realize the oil storage function. Then, it will be dispersed and discharged through the micro through hole 1 4, micro through hole 2 5 and micro through hole 3 6, thereby achieving continuous lubrication and improving the lubrication effect. The combined groove 2 can have the function of expansion and contraction compensation. When the support ring body 1 is deformed by heat, the combined groove 2 has the compensation space, thereby avoiding excessive friction between the support ring body 1 and the cylinder body.

[0024] The combined groove 2 is composed of an oil storage vertical groove 8, a flow guiding inclined groove 9 and an oil inlet flared groove 10. The oil storage vertical groove 8, the flow guiding inclined groove 9 and the oil inlet flared groove 10 are connected structures, and the oil inlet hole 3 is located inside the oil storage vertical groove 8.

[0025] The design of the oil storage vertical groove 8, the guide inclined groove 9 and the oil inlet flaring groove 10 can improve the oil storage effect. When the support ring body 1 moves down, the lubricating oil enters the interior of the guide inclined groove 9, and then continues to rise along the oil storage vertical groove 8 under the action of acceleration, so as to enter the interior of the oil inlet hole 3.

[0026] The bottom end of the arc-shaped outer surface of the support ring body 1 is provided with an annular groove 11 that communicates with the oil storage vertical groove 8 and the guide inclined groove 9, so that the lubricating oil inside the oil storage vertical groove 8 and the guide inclined groove 9 can enter the annular groove 11 to achieve full lubrication.

[0027] The diameter of the oil inlet hole 3 is larger than that of the micro through hole 1 4, micro through hole 2 5 and micro through hole 3 6, which can increase the oil inlet volume and achieve decentralized oil discharge.

[0028] An oil storage cotton core 12 is provided on the side inside the annular inner chamber 7. A hollow memory metal ring 13 is provided in the center of the oil storage cotton core 12. The hollow memory metal ring 13 is a fully enclosed structure. The oil storage cotton core 12 realizes the function of oil storage. After the hollow memory metal ring 13 is heated and deformed, it can squeeze the oil storage cotton core 12, so that the oil storage cotton core 12 releases lubricating oil or hydraulic oil.

[0029] An annular cover 14 is snapped onto the top of the annular inner chamber 7. The annular cover 14 is welded to the support ring body 1, which can seal the annular inner chamber 7.

[0030] The bottom of the annular inner chamber 7 is fixedly provided with several positioning seats 15 that match the hollow memory metal ring 13, and the bottom of the annular cover 14 is fixedly provided with several positioning seats 2 16 that match the hollow memory metal ring 13, which can realize the positioning of the hollow memory metal ring 13 and prevent the hollow memory metal ring 13 from shifting.

[0031] During operation, the system incorporates a combination of grooves, an oil inlet, three micro-through holes, and an annular inner chamber to achieve oil storage. This ensures efficient and comprehensive lubrication during the reciprocating motion of the support ring, reducing friction between the support ring and the cylinder and extending the support ring's service life. The combined groove design also provides expansion and contraction compensation, compensating for deformation caused by thermal deformation of the support ring and preventing increased friction with the cylinder. The combined groove, consisting of a vertical oil storage groove, a guide groove, and an flared oil inlet groove, enhances oil storage efficiency. The annular groove provides auxiliary lubrication, while the oil storage cotton core and hollow memory metal ring utilize thermal deformation to extrude lubricating oil, improving lubrication. Finally, the annular cap seals the annular inner chamber.
