Description

Technical Field

[0001] The utility model belongs to the technical field of engines, and in particular relates to a wear-resistant sealing cover for a rotor engine cylinder with strong sealing performance. Background Art

[0002] As a power conversion device, the engine is often used in various machines. It is a rotary engine that can directly convert the combustion expansion force of combustible gas into driving torque. Compared with traditional generators of the same power, it has the advantages of small size, light weight, low vibration and noise, and is widely used in small equipment.

[0003] At present, when the existing rotary engine is in use, the cylinder head will have a slight bounce between the cylinder body under the action of compression and combustion pressure. This slight bounce will cause the cylinder head gasket to relax and tighten, accelerating the wear of the gasket.

[0004] Therefore, in order to address the problem that when the above-mentioned existing rotary engine cylinder body faces slight bounce of the cylinder head, the sealing gasket will relax and tighten due to the loss of part of the external pressure, which will accelerate the wear of the sealing gasket and affect the sealing performance, a wear-resistant sealing cover for the rotary engine cylinder body with strong sealing performance is designed to reduce the adverse effects of slight bounce of the cylinder head. Utility Model Content

[0005] In order to overcome the problem that during the use of the existing rotary engine, slight bounce occurs between the cylinder head and the cylinder body, causing the sealing gasket to wear faster.

[0006] The technical solution of the utility model is: a wear-resistant sealing cover of a rotary engine cylinder with strong sealing performance, comprising a cylinder body, a cylinder head, a notch, a sealing component, and an elastic component; an air inlet and an air outlet are provided at the bottom end of the cylinder body, a rotor is arranged in the cylinder body, a cylinder head is arranged on the cylinder body, a notch is provided on the cylinder head, an output shaft matching the notch is fixedly connected to the rotor, a sealing component is arranged between the cylinder body and the cylinder head, and an elastic component is arranged between the sealing component and the cylinder head.

[0007] Preferably, by adding an elastic component between the sealing component and the cylinder head, the Tangxing component is used to compensate for the pressure loss due to the slight bounce between the cylinder head and the cylinder body, thereby improving the wear resistance of the sealing component and extending the service life of the sealing component, allowing the sealing component to play its role and avoiding leakage of gas, cooling water and lubricating oil.

[0008] Preferably, anchor holes are provided on both the cylinder body and the cylinder head, fixing bolts are inserted into the anchor holes, nuts close to the bottom end of the cylinder body are screwed on the fixing bolts, the anchor holes are arranged in a ring shape, the cylinder body and the cylinder head can be fixed together by bolts and nuts, and the sealing assembly is fixed between the cylinder head and the cylinder body by fixing, and the sealing assembly is used to prevent leakage of gas, cooling water and lubricating oil.

[0009] Preferably, the sealing assembly includes a groove and a protrusion; an annular groove is provided at the top of the cylinder body, and a protrusion matching the groove is inserted into the groove. The sealing cover can be fixed between the cylinder body and the cylinder head through the groove and the protrusion. The sealing cover fits tightly against the inner side of the cylinder head to form a seal to prevent leakage of gas, cooling water and lubricating oil. At the same time, the plug-in fixing method is tighter than the traditional close-fitting connection.

[0010] Preferably, the sealing assembly also includes a sealing cover and a through groove; one end of the convex buckle (502) is fixedly connected to the sealing cover, and a through groove matching the groove is provided on the sealing cover. The sealing cover is between the cylinder body and the cylinder head, filling the gap between the cylinder body and the cylinder head to prevent leakage of gas, cooling water and lubricating oil. The sealing cover can be made of plastic or metal.

[0011] Preferably, the output shaft passes through the notch and the through groove from the inside to the outside in sequence, and an anti-wear ring sleeved on the outside of the output shaft is arranged in the notch and the through groove. The output shaft passes through the notch and the through groove, and the output shaft and the rotor are driven to rotate by the motor as a driving element to start the rotor engine. The anti-wear ring can form a barrier between the output shaft and the notch and the through groove, thereby reducing the wear of the notch and the through groove.

[0012] Preferably, the elastic component includes a fixed column and a spring; the sealing cover is fixedly connected to the fixed column, and a spring with one end fixed to the sealing cover is sleeved on the fixed column. The fixed ring provides a guide for the expansion and contraction of the spring, so that the spring can only be extruded in the forward direction, avoiding left and right deformation when the spring is extruded.

[0013] Preferably, the elastic component also includes a recessed hole; a recessed hole matching the position of the fixed column is opened on the sealing cover, and a spring is arranged in the recessed hole, and the spring is squeezed through the recessed hole to provide pressure for the spring. During the use of the rotary engine, there is a slight bounce between the cylinder body and the cylinder head, and the cylinder head moves outward. After the spring loses part of the external force, it stretches and replaces the cylinder head to apply force to the sealing cover, thereby avoiding the process of loosening and tightening the sealing cover, and improving the wear resistance of the sealing cover.

[0014] Beneficial effects of the utility model:

[0015] 1. By installing an elastic component between the sealing component and the cylinder head, the elastic potential energy of the compressed elastic component is used to provide thrust for the sealing cover, so as to avoid the sealing cover from being loosened and compressed as the cylinder head loosens, slow down the wear of the sealing cover, increase the service life of the sealing cover, and ensure the sealing and wear resistance of the sealing cover;

[0016] 2. The sealing cover is inserted into the surface of the cylinder body through the convex buckle, and the sealing cover is clamped on the inner side of the cylinder head to be fixed. This fixing method makes the connection between the sealing cover and the cylinder body and cylinder head tighter, which can effectively prevent the leakage of gas, cooling water and lubricating oil.

The sealing assembly is fixed together, and the sealing assembly is fixed between the cylinder head 2 and the cylinder body 1. The sealing assembly is used to prevent the leakage of gas, cooling water and lubricating oil. The sealing cover 503 can be fixed between the cylinder body 1 and the cylinder head 2 through the groove 501 and the convex buckle 502. The sealing cover 503 is close to the inner side of the cylinder head 2 to form a seal to prevent the leakage of gas, cooling water and lubricating oil. At the same time, the plug-in fixing method is tighter than the traditional close-fitting connection. The sealing cover 503 is between the cylinder body 1 and the cylinder head 2, filling the gap between the cylinder body 1 and the cylinder head 2 to prevent the leakage of gas, cooling water and lubricating oil. The sealing cover 503 can be made of plastic or metal.

[0027] See also Figure 1 , 4, 6. In this embodiment, the output shaft passes through the notch 3 and the through groove 504 from the inside to the outside in sequence, and the notch 3 and the through groove 504 are provided with an anti-wear ring 6 sleeved on the outside of the output shaft, and the elastic component includes a fixing column 701 and a spring 702; the sealing cover 503 is fixedly connected with the fixing column 701, and the fixing column 701 is sleeved with a spring 702 with one end fixed on the sealing cover 503, and the elastic component also includes a concave hole 703; the sealing cover 503 is provided with a concave hole 703 that matches the position of the fixing column 701, and the spring 702 is arranged in the concave hole 703. The output shaft passes through the notch 3 and the through groove 504, and the output shaft and the rotor are driven to rotate by the motor as a driving element to realize starting the rotor. The engine, the anti-wear ring 6 can form a barrier between the output shaft and the notch 3 and the through groove 504, reducing the wear of the notch 3 and the through groove 504, the fixing ring provides a guide for the expansion and contraction of the spring 702, so that the spring 702 can only be extruded in the forward direction, avoiding left and right deformation when the spring 702 is extruded, and the spring 702 is extruded through the concave hole 703 to provide pressure for the spring 702.
