[0015] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0019] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is typically placed when in use, or are the orientations or positional relationships commonly understood by those skilled in the art. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 and Figure 2 As shown, a gear chamber structure for a diesel engine includes a gear chamber body 1, which includes a first shell and a second shell. A gear chamber for installing a gear is opened on the gear chamber body 1. In this embodiment, the gear chamber is opened on the front end face of the first shell of the gear body, an air compressor mounting interface 2 is opened on the upper right end of the gear chamber body 1, a hydraulic pump mounting interface 3 is opened on the lower right end of the gear chamber body 1, and a chamber is opened on the rear end face of the second shell. Furthermore, an idler shaft locating pin hole 54 is opened in the middle of the gear chamber body 1 to provide precise positioning for the idler gear and improve the gear meshing effect.

[0022] In this embodiment, if Figure 1 As shown, positioning pin holes 5 are opened on the gear chamber body 1 located on the lower left side and top of the gear chamber, thereby forming a positioning structure with double positioning pin holes 5, which can effectively ensure the coplanarity of the bottom surface of the gear chamber and the bottom surface of the body, ensuring the performance and reliability of the engine.

[0023] In this embodiment, if Figure 1 and Figure 2As shown, reinforcing ribs are provided on both the inner and outer surfaces of the gear chamber body 1. The reinforcing ribs are radial reinforcing ribs, and the radial reinforcing ribs radiate with the corresponding holes as the center, which can significantly improve the strength of the area around the holes, effectively reduce the risk of deformation or damage caused by stress concentration at the holes, and help to improve the stability of the entire component. In this embodiment, the inner surface of the gear chamber body 1 is provided with a first radial reinforcing rib 6, and the outer surface of the gear chamber body 1 is provided with a second radial reinforcing rib 7.

[0024] In this embodiment, the air compressor mounting interface 2 is integrally cast, and further, the hydraulic pump mounting interface 3 is integrally cast, thereby facilitating the manufacture of the entire gear chamber structure.

The hydraulic pump 9 and the air compressor 8 are integrated on the gear chamber body 1, so that the gear chamber can rotatably install multiple parts, which has the advantage of multiple integrated functions, and can meet the accessory installation requirements on a single engine, avoiding the waste of development, design and production of too many types of parts requiring accessory interfaces, and can make the engine's matching surface more extensive. Therefore, the gear chamber structure used in this oil production machine integrates multiple functional modules in a compact space, making the engine structure more compact.
