[0002] On agricultural machinery equipment such as lawn mowers and harvesters, a small engine is usually used to control the rotation speed of the harvesting device, and the rotation speed of the crank is controlled by the piston. Therefore, an installation hole for a camshaft is generally opened on the engine side cover, and the camshaft is used as the output shaft. Through the transmission of transmission parts such as gears, the control of the rotation speed is realized;

[0003] Regarding the rotation speed of the output shaft, the requirements of different customers are different. For engines of different models, the requirements for the output shaft may also be different. It may be the camshaft as the output, or it may be the crankshaft as the output. In this way, it is necessary to manufacture multiple different types of side covers to meet the installation of different output shafts, which greatly increases the production cost. Therefore, in order to meet the needs of different customers and enable a single side cover to meet the installation of different output shafts, this engine side cover is designed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an engine side cover. By opening a camshaft installation hole, a crankshaft reserved boss and a reserved groove, the output shaft can be installed at these three different positions. At the same time, a sealing plate is installed through the sealing plate reserved hole to block different positions, improving the applicable range of the side cover and enabling the installation of output shafts at different positions.

[0005] The utility model provides the following technical solution: an engine side cover, including a side cover body. A camshaft installation hole, a crankshaft reserved boss and a reserved groove are opened on the side surface of the side cover body. A plurality of sealing plate reserved holes are formed on the outer sides of the crankshaft reserved boss and the camshaft installation hole, and the sealing plate reserved holes are formed on the front surface of the side cover body.

[0006] In order to enhance the connection strength between the sealing plate and the side cover, the sealing plate reserved holes are distributed in a rectangular shape, with the crankshaft reserved boss and the camshaft installation hole as the centers respectively.

[0007] In order to enhance the support strength of the side cover for the output shaft, reinforcing rings are formed on the back surfaces of the camshaft installation hole, the crankshaft reserved boss and the reserved groove, and the reinforcing rings of the camshaft installation hole and the crankshaft reserved boss form an 8-shaped boss.

[0008] In order to facilitate the detection of the oil level of the engine, oil level measurement ports are formed on both side surfaces of the side cover body, and threads are formed on the inner walls of the oil level measurement ports for connecting an oil dipstick.

[0009] In order to increase the connection strength between the side cover body and the machine body, a side edge is formed on the outer edge of the side cover body, and a plurality of connection holes are provided on the side edge.

[0010] In order to change the oil of the engine, an oil outlet hole is further provided on the front surface of the side cover body, and the oil outlet hole is located close to the bottom surface side.

[0011] In order to enhance the rigidity of the side cover body, reinforcing ribs are formed on the back surface of the side cover body, and the reinforcing ribs are distributed between the reinforcing ring and the side edge.

[0012] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows: By providing a camshaft mounting hole, a crankshaft reserved boss and a reserved groove, the output shaft can be installed at these three different positions. At the same time, a sealing plate reserved hole is formed on the outer side of the camshaft mounting hole and the crankshaft reserved boss, and different positions are blocked by the sealing plate to keep the side cover sealed. This structure improves the applicable range of the side cover and can install the output shaft at different positions. BRIEF DESCRIPTION OF THE DRAWINGS

The camshaft mounting hole 2 is used for mounting the camshaft, the crankshaft reserved boss 3 is used for reserving a position for mounting the crankshaft, and the reserved groove 4 is also used for reserving a position for mounting the camshaft on the other side, so that the side cover can adapt to the installation of different output shafts, improving the applicable range and reducing the production cost at the same time. On the outer sides of the crankshaft reserved boss 3 and the camshaft mounting hole 2, a plurality of sealing plate reserved holes 9 are formed. The sealing plate reserved holes 9 are formed on the front surface of the side cover body 1 and are used for connecting a sealing plate through fasteners to block the crankshaft reserved boss 3 or the camshaft mounting hole 2, so as to keep the side wall of the engine sealed.

[0020] The sealing plate reserved holes 9 are distributed in a rectangular shape, centered on the crankshaft reserved boss 3 and the camshaft mounting hole 2 respectively, so that the sealing plate has high installation strength and improves the sealing performance between the sealing plate and the side cover body 1.

[0021] As Figure 2 shown, on the back surfaces of the camshaft mounting hole 2, the crankshaft reserved boss 3, and the reserved groove 4, a reinforcing ring 10 is formed. The reinforcing rings 10 of the camshaft mounting hole 2 and the crankshaft reserved boss 3 form an 8-shaped boss. The formation of the reinforcing ring 10 enhances the strength of the camshaft mounting hole 2 and the crankshaft reserved boss 3, so that the side cover body 1 can adapt to the installation requirements of different output shafts.

[0022] As Figure 3 shown, on both side surfaces of the side cover body 1, oil measuring ports 6 are respectively formed. On the inner wall of the oil measuring port 6, threads are formed for connecting an oil dipstick to facilitate the detection of the oil level.

[0023] On the outer edge 11 of the side cover body 1, a side edge 11 is formed. The side edge 11 increases the contact area between the side cover body 1 and the engine body and enhances the connection strength. A plurality of connection holes 8 are provided on the side edge 11, and connecting fasteners in the connection holes 8 enhance the connection strength between the side cover body 1 and the engine body.

[0024] On the front surface of the side cover body 1, an oil outlet hole 5 is also provided. The oil outlet hole 5 is located near the bottom surface side, and the engine oil at the bottom of the engine is discharged through the oil outlet hole 5. The oil outlet hole 5 is sealed by a bolt and a gasket.

[0025] On the back surface of the side cover body 1, reinforcing ribs 7 are formed. The reinforcing ribs 7 are distributed between the reinforcing ring 10 and the side edge 11 to improve the strength and rigidity of the camshaft mounting hole 2, the crankshaft reserved boss 3, and the reserved groove 4, so that the side cover meets the use requirements.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
