Problems solved by technology

[0003] The above-mentioned bearing pad type transmission structure has the following problems: 1. The structure is complex and the number of parts is large; 2. The lubricating oil circuit is complicated, and the failure rate of the gear lock is high due to insufficient lubrication; 3. Because the gears and other parts are installed inside the gear chamber, If a fault occurs, the gear chamber cover needs to be removed, which is poor in maintainability; 4. Due to structural limitations, the hydraulic pump mounting bolts pass through the gear chamber to the gear chamber cavity, which may cause oil leakage

Abstract

The invention discloses an auxiliary power output structure of a diesel engine. The auxiliary power output structure is used for mounting a hydraulic pump and providing power for the hydraulic pump. A gear chamber of the diesel engine and the side face of a gear chamber cover are provided with mounting connectors. The auxiliary power output structure comprises a mounting connecting block and a hydraulic pump gear. The mounting connecting block is provided with a chamber for mounting a gear. The mounting connecting block is provided with a mounting end opening and a hydraulic pump mounting end. The mounting end opening and the mounting connecting opening are matched. The chamber is communicated with the gear chamber. The hydraulic pump gear is arranged in the chamber through a bearing pack. The bearing pack comprises an inner bearing and an outer bearing. The hydraulic pump gear protrudes out of the mounting end opening and can be meshed with the gear in the gear chamber. Lubricating oil in the gear chamber can directly lubricate the hydraulic pump gear and the bearing pack. The structure is convenient to mount and maintain, lubricating is easy, and the structure is simple.

Description

Technical field [0001] The present invention relates to the field of engines, in particular to an auxiliary power output structure of a diesel engine used for installing and driving a hydraulic pump. Background technique [0002] Existing diesel engine auxiliary power output structures for installing and driving hydraulic pumps generally have two typical structures. The hydraulic pump gears of the two auxiliary power output structures are lined-mounted. The main difference is that the lubricating oil circuit is different. Figure 1 to Figure 3 As shown, both structures lubricate the gear bushing 5 by providing an oil passage on the inner wall of the hydraulic pump mounting shaft 7. In the first structure, the lubricating oil entering the oil passage of the hydraulic pump mounting shaft 7 passes through The lubricating oil pipe 9 inside the gear chamber 2 enters (see figure 2 ), in the second structure, the lubricating oil entering the oil passage of the hydraulic pump mounting sha...
