Description

Technical Field

[0001] This utility model belongs to the field of oil scraper technology, specifically an oil scraper ring for a piston compressor. Background Technology

[0002] An oil scraper ring is a type of oil ring used to scrape off lubricating oil from the inner wall of a cylinder. It's a crucial component in reciprocating compressors for scraping and controlling the lubricating oil on the cylinder walls. As the piston rod moves from the crankcase side to the cylinder side, excess lubricating oil splashed from the crosshead adheres to its surface. The cutting edge of the oil scraper ring "scrapes" off this excess oil, preventing excessive oil from entering the cylinder. However, with existing oil scraper rings, after a certain period of use, wear and replacement are necessary. Because the oil scraper ring is a single unit, the entire ring needs to be replaced, increasing the operating cost. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a piston compressor oil scraper ring, which solves the problem that when the oil scraper ring wears out after a certain period of use and needs to be replaced, the oil scraper ring is an integral piece, which requires replacing the entire oil scraper ring and increases the cost of using the oil scraper ring.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a piston compressor oil scraper ring, comprising a mounting ring, wherein several positioning holes are respectively opened on both sides of the top of the mounting ring, four countersunk holes are opened on the top of the mounting ring, a connecting ring is installed at the bottom of the mounting ring, several positioning holes are respectively opened on both sides of the top of the connecting ring, the positioning holes are corresponding to the positioning holes, four connecting holes are opened on the top of the connecting ring, the connecting holes are corresponding to the countersunk holes, a cutting ring is provided at the bottom of the connecting ring, four limiting holes are opened on the top of the cutting ring, the limiting holes are connected to the countersunk holes and the connecting holes, and four fixing bolts are provided on the top of the mounting ring, the fixing bolts passing through the countersunk holes, the connecting holes and the limiting holes and threadedly connected.

[0005] As a further embodiment of this utility model: several positioning posts are fixedly connected to both sides of the top of the mounting ring, and the positioning posts correspond to the positions of positioning hole two and positioning hole one.

[0006] As a further embodiment of this utility model: a fixing ring is installed at the top of the inner side of the connecting ring, and the fixing ring is tightly attached to the bottom of the mounting ring.

[0007] As a further embodiment of this utility model: an elastic ring is installed inside the fixing ring, and the elastic ring is made of rubber.

[0008] As a further embodiment of this utility model: several sliding balls are provided at the middle position of the outer wall of the connecting ring, and the sliding balls are made of metal.

[0009] As a further embodiment of this utility model: several oil scraper seats are fixedly connected to the bottom of the blade ring, and a blade edge is provided at the bottom of the blade ring between the oil scraper seats.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The oil scraper ring of this piston compressor is configured with a positioning post, fixing bolt, connecting hole and mounting ring. After aligning the positioning hole one and positioning hole two on the surface of the mounting ring and the connecting ring with the positioning post, the mounting ring and the connecting ring are moved so that the mounting ring and the connecting ring drive the positioning hole one and positioning hole two to insert into the top of the positioning post, thereby positioning the mounting ring and the connecting ring on the top of the blade ring. The fixing bolt is rotated so that the fixing bolt passes through the countersunk hole, the connecting hole and the limit hole in sequence to form a threaded connection, thereby realizing the assembly of the oil scraper ring, which facilitates the subsequent replacement of worn parts and reduces the use cost of the oil scraper ring; 2. The oil scraper ring of this piston compressor is equipped with a sliding ball, an oil scraper seat, an elastic ring, and a cutting edge. As the piston rod moves, the elastic ring drives the fixed ring to move, thereby allowing the sliding ball outside the fixed ring to move together to reduce the friction on the oil scraper ring. At the same time, the fixed ring drives the cutting edge and the oil scraper seat to slide together through the cutting edge, so that the oil scraper seat can cooperate with the cutting edge to perform oil scraping.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3As shown, this utility model provides a technical solution: a piston compressor oil scraper ring, including a mounting ring 1, with several positioning pins 9 fixedly connected to both sides of the top of the mounting ring 1. The positioning pins 9 correspond to the positioning holes 2 and 3. By setting the positioning pins 9, the positioning pins 9 are inserted into the positioning holes 2 and 3, thereby positioning the mounting ring 1 and the connecting ring 4 on the top of the blade ring 7. The mounting ring 1 has several positioning holes 2 on both sides of the top. The mounting ring 1 has four countersunk holes 3 on the top. By setting the countersunk holes 3, the fixing bolt 10 can be completely turned into the countersunk hole 3, so that the countersunk hole 3 completely covers the fixing bolt 10, reducing the impact of the external environment on the fixing bolt 10 during use. A connecting ring 4 is installed at the bottom of the mounting ring 1, and a fixing ring 11 is installed at the top inside the connecting ring 4. The fixing ring 11 is close to the bottom of the mounting ring 1. By setting the fixing ring 11, the fixing ring 11 is installed between the mounting ring 1 and the connecting ring 4, thereby realizing the installation of the elastic ring 12 inside the mounting ring 1 and the connecting ring 4. An elastic ring 12 is installed inside the fixed ring 11. The elastic ring 12 is made of rubber. By setting the elastic ring 12, the elastic ring 12 can contact the piston rod, thereby increasing the friction with the piston rod, so that the piston rod can drive the oil scraper ring to move through the elastic ring 12. Several sliding balls 13 are provided in the middle of the outer wall of the connecting ring 4. The sliding balls 13 are made of metal. By setting the sliding balls 13, the sliding balls 13 of the connecting ring 4 can rotate together with the moving mounting ring 1, thereby reducing the friction on the mounting ring 1. Several positioning holes 2 5 are provided on both sides of the top of the connecting ring 4. The positioning holes 2 5 correspond to the positioning holes 1 2. Four connecting holes 6 are provided on the top of the connecting ring 4. The connecting holes 6 correspond to the countersunk holes 3. A blade ring 7 is provided at the bottom of the connecting ring 4. Several oil scraper seats 15 are fixedly connected to the bottom of the blade ring 7. A cutting edge 14 is provided at the bottom of the blade ring 7 between the oil scraper seats 15. By setting the oil scraper seats 15, the bottom shape of the oil scraper seats 15 is uneven, which improves the oil scraping effect of the oil scraper seats 15 on the lubricating oil. The top of the cutting ring 7 has four limiting holes 8, which are connected to the countersunk hole 3 and the connecting hole 6. The top of the mounting ring 1 has four fixing bolts 10, which pass through the countersunk hole 3, the connecting hole 6 and the limiting hole 8 and are threaded together. By setting the fixing bolts 10, which pass through the countersunk hole 3, the connecting hole 6 and the limiting hole 8 and are threaded together, the cutting ring 7, the mounting ring 1 and the connecting ring 4 can be fixedly installed.

[0014] The working principle of this utility model is as follows: Align the positioning holes 2 and 5 on the surfaces of the mounting ring 1 and connecting ring 4 with the positioning post 9. Then, move the connecting ring 4, fixing ring 11, and mounting ring 1 down in sequence so that the positioning holes 2 and 5 are inserted into the positioning post 9. This allows the connecting ring 4 and mounting ring 1 to be positioned on top of the blade ring 7. Align the fixing bolt 10 with the countersunk hole 3 and move the fixing bolt 10 down so that it passes through the countersunk hole 3 and connecting hole 6 and is threaded into the limiting hole 8. This completes the splicing and installation of the oil scraper ring. Then, install the oil scraper ring behind the piston rod so that the elastic ring 12 is close to the piston rod. As the piston rod moves, the elastic ring 12 and fixing ring 11 drive the mounting ring 1 and connecting ring 4 to move, thereby allowing the sliding ball 13 outside the connecting ring 4 to slide and reduce the friction of the connecting ring 4. At the same time, the blade ring 7 moves with the connecting ring 4, causing the cutting edge 14 and the oil scraper seat 15 to scrape the lubricating oil.
