Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to a high-efficiency engine with forward and reverse rotation output. Background Technology

[0002] A gasoline engine is a machine that converts chemical energy into mechanical energy. It is a type of engine that mainly generates kinetic energy by burning fuel in the cylinder. Gasoline engines typically use gasoline as fuel. The fuel is injected into the cylinder through a gasoline injection system. After being compressed to a certain temperature and pressure, it is ignited by a spark plug, causing the gas to expand and do work. Gasoline engines are characterized by high speed, simple structure, light weight, low cost, smooth operation, and convenient use and maintenance.

[0003] In the existing technology, many types of gasoline engines cannot achieve reverse operation due to their structure, which makes them inconvenient to use. Currently, only forward-rotating engines are available on the market, which has great limitations. Some special-purpose end products require gasoline engines that can rotate in both forward and reverse directions. Therefore, a high-efficiency engine with forward and reverse output is needed. The design of this solution can achieve the following benefits: the forward and reverse rotation of marine engines can be used to exit the ship after it enters the dock; and garden tillers can achieve forward and reverse operation for ditching operations in the field.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This high-efficiency engine with forward and reverse output: When the engine output shaft rotates forward, the main shaft double-toothed pinion meshes with the first output shaft gear, and the shift fork shaft drives the shift fork to push the sliding nest to mesh with the first output shaft gear.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Please see Figure 1-5This utility model provides a technical solution: a high-efficiency engine with forward and reverse output, including a gearbox 1. An engine output shaft 2 is rotatably connected inside the gearbox 1. A first output shaft gear 6 and a second output shaft gear 7 are fitted onto the outer surface of the engine output shaft 2. A sliding nest 12 is provided on the outer surface of the engine output shaft 2, located between the first output shaft gear 6 and the second output shaft gear 7. A main shaft double-toothed large gear 4 and a main shaft double-toothed small gear 13 are provided on one side of the gearbox 1 via a rotating shaft. An intermediate shaft double-toothed small gear 5 and an intermediate shaft double-toothed large gear 14 are also provided on one side of the gearbox 1 via a rotating shaft. The main shaft double-toothed small gear 13 meshes with the first output shaft gear 6, and the main shaft double-toothed large gear 4 and the intermediate shaft double-toothed large gear 5 are connected via a rotating shaft. Gear 14 meshes with the intermediate shaft double gear pinion 5 and the second output shaft gear 7. When the engine is running and the engine output shaft 2 rotates forward, the main shaft double gear pinion 13 meshes with the first output shaft gear 6. The shift fork shaft 16 drives the shift fork 11, which in turn pushes the sliding nest 12 to mesh with the first output shaft gear 6. When the engine output shaft 2 rotates in reverse, the main shaft double gear large gear 4 meshes with the intermediate shaft double gear large gear 14, and the intermediate shaft double gear pinion 5 meshes with the second output shaft gear 7. The shift fork shaft 16 drives the shift fork 11, which in turn pushes the sliding nest 12 to mesh with the second output shaft gear 7. This achieves forward and reverse rotation of the engine, thus solving the problem that gasoline engines cannot operate in reverse and addressing the need for reverse rotation in some specific end-use products on the market.

[0027] Furthermore, the surface of the gearbox 1 is provided with a pressure relief bolt 3, which is used to release pressure when the gearbox oil pressure is too high. The surface of the gearbox 1 is provided with a gearbox lubricating oil filler port 15 for adding lubricating oil to the inside. The surface of the gearbox 1 is provided with a shift fork shaft 16, which swings left and right to have three gears, thereby realizing the forward rotation, neutral, and reverse rotation of the engine output shaft 2. The surface of the gearbox 1 is provided with a shift fork 11, the inside of the shift fork 11 is provided with a shift lever 8, the outer surface of the shift lever 8 is provided with a ball 9, and the top of the ball 9 is provided with a spring 10.

[0028] Working principle: When the engine is running and the engine output shaft 2 rotates forward, the main shaft double-tooth pinion 13 meshes with the first output shaft gear 6, which drives the shift fork shaft 16 to drive the shift fork 11 and then pushes the sliding nest 12 to mesh with the first output shaft gear 6. When the engine output shaft 2 rotates in reverse, the main shaft double-tooth large gear 4 meshes with the intermediate shaft double-tooth large gear 14, and the intermediate shaft double-tooth pinion 5 meshes with the second output shaft gear 7. The shift fork shaft 16 drives the shift fork 11 and then pushes the sliding nest 12 to mesh with the second output shaft gear 7, thereby realizing the forward and reverse rotation of the engine. The pressure relief bolt 3 provided on the surface of the gearbox 1 is used to release pressure when the gearbox oil pressure is too high. The gearbox lubricating oil filler port 15 is used to add lubricating oil to the inside.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
