Description

Technical Field

[0001] This utility model belongs to the field of generator technology, and specifically refers to a cylinder mounting structure for a generator. Background Technology

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. Driven by a water turbine, steam turbine, diesel engine, or other power machinery, it converts energy from water flow, airflow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator and converted into electrical energy. The generator's cylinder block is one of the core components of the engine; together with the cylinder head and piston top, it forms the combustion chamber, participating in the compression and combustion of the air-fuel mixture.

[0003] Currently, a Chinese patent discloses an oil-gas separation mechanism for a generator power system [Authorization Announcement No.: CN208267931U]. The cylinder body is fixed with four screws arranged in a rectangular shape. The structure of the cylinder body is not stable enough and it is prone to loosening and affecting the sealing performance after long-term use. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a cylinder mounting structure for a generator. The technical problem to be solved by this utility model is: how to solve the problem of poor stability and easy loosening of the cylinder mounting.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A cylinder mounting structure for a generator includes a crankcase and a cylinder block, wherein the crankcase has a cylinder block mounting portion, and the cylinder block is fixed to the cylinder block mounting portion by bolts, characterized in that the bolts include two bolts one, two bolts two, and one bolt three, and the axial projections of the two bolts one, two bolts two, and one bolt three are respectively distributed at the five corners of the pentagon.

[0007] The cylinder block and the cylinder block mounting part of this structure are fixed together by five bolts. The five bolts are distributed in a pentagonal structure. By increasing the number of bolts by only one, the distribution shape of the bolts is changed, which significantly improves the firmness and stability of the cylinder block installation. This results in good sealing between the cylinder block and the cylinder block mounting part, making the cylinder block less prone to loosening and extending its service life.

[0008] In the aforementioned cylinder mounting structure for a generator, the cylinder mounting portion has a circular cylinder opening, with two bolts (one), two bolts (two), and one bolt (three) spaced circumferentially around the cylinder opening. When the five bolts are arranged in a pentagonal pattern, and are also spaced circumferentially around the cylinder opening, this ensures a tight fit between the cylinder and the mounting portion, preventing leakage at the cylinder opening.

[0009] In the aforementioned cylinder mounting structure of a generator, the cylinder has a rocker arm cavity. Two bolts (bolt 1) are located outside the rocker arm cavity, while two bolts (bolt 2) and one bolt (bolt 3) are located inside the rocker arm cavity. This structure has two bolts located outside the rocker arm cavity and the other three bolts located inside, resulting in a relatively balanced distribution of bolts inside and outside the rocker arm cavity, while also ensuring sufficient space within the rocker arm cavity.

[0010] In the aforementioned cylinder mounting structure for a generator, two bolts are located on the left and right sides of the upper part of the cylinder, two bolts are located on the left and right sides of the middle part of the cylinder, and a third bolt is located at the lower part of the cylinder. Bolts are distributed at the upper, middle, and lower parts of the cylinder, ensuring that all parts of the cylinder are locked in place, further improving the stability and firmness of the cylinder mounting.

[0011] In the aforementioned cylinder mounting structure of a generator, the rocker arm cavity has a rocker arm hinge seat, with two bolts (2) located on the left and right sides of the rocker arm hinge seat respectively. The cylinder body has two push rod holes, and bolt (3) is positioned between the two push rod holes, below the rocker arm hinge seat. The two bolts (2) and one bolt (3) are located at corner positions within the rocker arm cavity, resulting in a very compact structure that minimizes the space occupied within the rocker arm cavity and does not affect the installation of other components within the rocker arm cavity.

[0012] Compared with the prior art, the cylinder mounting structure of the generator of this utility model has the following advantages: The cylinder and the cylinder mounting part of this structure are fixed by five bolts. The distribution of the five bolts is in a pentagonal structure. By increasing the number of bolts by only one, the firmness and stability of the cylinder mounting are significantly improved by changing the distribution shape of the bolts. This results in good sealing between the cylinder and the cylinder mounting part, the cylinder is not easy to loosen, and the service life of the cylinder is long. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the cylinder mounting structure of this generator includes a crankcase 1 and a cylinder block 2. The crankcase 1 has a cylinder block mounting part 100. The cylinder block 2 is fixed to the cylinder block mounting part 100 by bolts, including two bolts 3, two bolts 4, and one bolt 5. The axial projections of the two bolts 3, two bolts 4, and one bolt 5 are distributed at the five corners of a pentagon. In this structure, the cylinder block 2 is fixed to the cylinder block mounting part 100 by five bolts arranged in a pentagonal pattern. By increasing the number of bolts by only one, the distribution shape of the bolts significantly improves the firmness and stability of the cylinder block 2 installation, resulting in good sealing between the cylinder block 2 and the cylinder block mounting part 100, preventing the cylinder block from loosening, and extending the service life of the cylinder block 2. The cylinder block mounting part 100 has a circular cylinder opening 101, with the two bolts 3, two bolts 4, and one bolt 5 spaced circumferentially along the cylinder opening 101. With the five bolts arranged in a pentagonal structure, and the five bolts also distributed circumferentially around the cylinder port 101, the cylinder body 2 and the cylinder body mounting part 100 are tightly fitted together, and no leakage occurs at the cylinder port 101.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the cylinder body 2 has a rocker arm cavity 6. Two bolts 1 (3) are located outside the rocker arm cavity 6, while two bolts 2 (4) and one bolt 3 (5) are located inside the rocker arm cavity 6. The distribution of bolts inside and outside the rocker arm cavity 6 is relatively balanced, ensuring sufficient space within the cavity. Furthermore, two bolts 1 (3) are located on the left and right sides of the upper part of the cylinder body 2, two bolts 2 (4) are located on the left and right sides of the middle part of the cylinder body 2, and bolt 3 (5) is located at the lower part of the cylinder body 2. The distance between the two bolts 1 (3) is less than the distance between the two bolts 2 (4). Bolts are distributed in the upper, middle, and lower parts of the cylinder body 2, ensuring that all parts are locked in place, further improving the stability and firmness of the cylinder body 2 installation.

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the rocker arm cavity 6 has a rocker arm hinge seat 20, with two bolts 4 located on the left and right sides of the rocker arm hinge seat 20 respectively. The cylinder body 2 has two push rod holes 21, and a bolt 5 is located between the two push rod holes 21, below the rocker arm hinge seat 20. The two bolts 4 and one bolt 5 are located in the corners of the rocker arm cavity 6, resulting in a very compact structure that minimizes the space occupied within the rocker arm cavity 6 and does not affect the installation of the various components within the rocker arm cavity 6.
