Description

Technical Field

[0001] The present application relates to the field of piston rings, and more particularly to a wear-resistant piston ring set. Background Art

[0002] The piston ring is a metal ring embedded in the piston groove. There are two types of piston rings: compression ring and oil ring. The compression ring can be used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape off excess oil on the cylinder. The piston ring is a metal elastic ring with a large outward expansion deformation. It is assembled into the cross-section and the corresponding annular groove.

[0003] Some existing piston rings are made of steel or cast iron, cast, ground, heat treated, and ground into a ring-shaped body. Some piston rings currently used are bent when used and then sleeved into the annular groove opened at the installation position. Since the bending may cause slight deformation, friction may occur during use. The piston ring is often deformed or even broken due to friction, which directly affects the sealing performance. Therefore, in order to solve the above problems, we propose a wear-resistant piston ring kit. Utility Model Content

[0004] In order to solve the above problems, the present application provides a wear-resistant piston ring kit, which adopts the following technical solution:

[0005] A wear-resistant piston ring kit includes a piston ring body, the piston ring body includes a first half ring and a second half ring arranged on one side of the first half ring, the first half ring is fixedly mounted with two symmetrically distributed plug blocks on a side close to the second half ring, the second half ring is provided with a slot matching the plug blocks in the same group on a side close to the first half ring, a fixing component is provided between the plug blocks and the slots in the same group, and the first half ring and the second half ring are both sleeved with wear-resistant sleeves on the outside.

[0006] By adopting the above technical solution, when the equipment is used, the staff places the first half ring and the second half ring at the installation position, and the plug installed on the side wall of the first half ring is engaged with the slot opened on the side wall of the second half ring. The engagement of the plug and the slot plays a role in positioning and splicing the first half ring and the second half ring. A fixing component is provided between the plug and the slot in the same group, which plays a role in fixing the plug, and then plays a role in positioning and fixing the first half ring and the second half ring, which is convenient for the subsequent sealing use of the product. The wear-resistant sleeve is arranged on the outside of the piston ring body, which is beneficial to improving the wear resistance of the product, and then plays a role in protecting the product, which is beneficial to maintaining the service life of the product.

[0007] Furthermore, the fixing assembly includes a positioning block fixedly installed on the inner wall of the slot away from the first half ring, two of the positioning blocks are provided with positioning grooves matching the positioning blocks on the same side close to the first half ring, the positioning blocks are provided with receiving grooves at the top and bottom ends of a section close to the first half ring, the two receiving grooves are hinged with fixing blocks at the top of the inner wall close to the first half ring, springs are fixedly connected between the inner walls of the two fixing blocks on the side close to the positioning blocks and opposite to the receiving grooves in the same group, and the inner wall of the slot is provided with a fixing groove matching the fixing block on the same side.

[0008] By adopting the above technical solution, a positioning block is provided inside the slot, and when the plug-in block moves into the same group of slots, the positioning block moves into the positioning groove opened on the side wall of the plug-in block in the same group, and fixed blocks are provided on both sides of the positioning block. When the positioning block moves into the positioning groove, an arc chamfer is opened on one side of the fixed block. Therefore, the fixed block rotates into the same group of storage grooves under the pressure of the side wall of the positioning groove, and the fixed block pushes the same group of springs to contract. When the positioning block is completely engaged with the positioning groove, the fixed block is separated from the storage groove under the elastic rebound of the spring, so that the fixed block is engaged with the fixing groove opened on the inner wall of the slot. Through the engagement of the fixed block and the fixing groove, the plug-in block can be positioned and fixed, and then the first half ring and the second half ring can be fixedly spliced, which is convenient for the subsequent use of the product.

[0009] Furthermore, a fastening ring is sleeved on the outer side of the piston ring body, and an annular groove matching the fastening ring is opened on the outer side of the piston ring body.

[0010] By adopting the above technical solution, when the first half ring and the second half ring are spliced ​​at the installation location, the fastening ring is sleeved on the outside of the piston ring body, and the fastening ring is engaged with the annular groove on the outside of the piston ring body, which can further fix the first half ring and the second half ring, which is beneficial to improve the stability of the splicing of the first half ring and the second half ring. The fastening ring is made of rubber, and the outside of the fastening ring is flush with the outside of the piston ring body, which makes it easy for the fastening ring to be sleeved on the outside of the piston ring body without affecting the subsequent use of the product.

[0011] Furthermore, the top and bottom ends of the piston ring body are both provided with a heat-resistant layer.

[0012] By adopting the above technical solution, the heat-resistant layer makes the product resistant to high temperatures.

[0013] Furthermore, the inner side of the piston ring body is provided with grooves distributed in a ring array, and rubber pads are provided in the grooves.

[0014] By adopting the above technical solution, the inner side of the piston ring body is provided with a rubber pad, which is helpful to reduce the wear degree of the inner side of the piston ring body.

[0015] Furthermore, the wear-resistant sleeve is made of chromium alloy.

[0016] By adopting the above technical solution, the wear-resistant layer is made of chromium alloy, so that the piston ring body has better wear resistance, thereby achieving the effect of protecting the product.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] (1) In the present application, the first half ring and the second half ring are spliced ​​together by setting a fixed component, which is convenient for the staff to install. In addition, a wear-resistant sleeve is set on the outer side of the piston ring body. The material of the wear-resistant sleeve is chrome alloy, which makes the piston ring body have better wear resistance and achieves the effect of protecting the product.

[0019] (2) In the present application, a heat-resistant layer is provided on the outer side of the piston ring to make the product resistant to high temperatures.
