Gear lubrication oil path

Abstract

The invention discloses a gear lubrication oil path applied to engine gear lubrication. The gear lubrication oil path comprises an oil groove cast to the gear installing end face of an engine body. The oil groove is connected with a main oil way of the engine body. A gear chamber cover plate covers the gear installing end of the engine body in a covering manner. The gear lubrication oil path is formed through closing of the gear chamber cover plate and the oil groove. The oil groove of the gear lubrication oil path is formed through casting, machining is not needed, the machining abrasion of the engine body is reduced, and gears at multiple positions can be effectively lubricated through a plurality of through holes in the gear chamber cover plate.

Description

technical field [0001] The invention relates to the field of engines, in particular to a gear lubricating oil circuit for gear lubrication of the engine. Background technique [0002] At present, the gear and sliding bearings designed on the machine body are lubricated by internal machining and drilling, and the drilling is connected with the main oil passage to form a closed oil passage. Figure 6 is a schematic diagram of the gear mounting end of an engine block according to the prior art. Figure 7 It is a schematic cross-sectional view of the gear installation end of the engine body according to the prior art. Such as Figure 6 and Figure 7 As shown, the gear oil passage 5 of the prior art needs to be formed by drilling holes on the engine body through machining, which leads to the following disadvantages in the prior art: 1. The oil hole needs to be machined, which wastes materials and leads to production failure. The efficiency is slow, and the manufacturing cost is...

Problems solved by technology

like Image 6 and Figure 7 As shown, the gear oil passage 5 of the prior art needs to be formed by drilling holes on the engine body through machining, which leads to the following disadvantages in the prior art: 1. The oil hole needs to be machined, which wastes materials and leads to production failure. The efficiency is slow, and the manufacturing cost is increased; 2. The length of the drilling hole is relatively long, which may easily cause the drill to be out of position and deflect, resulting in the break of the drill

[0003] How to solve the problem of relying on machining in the design of gear lubricating oil circuit, resulting in high cost, slow cycle, and poor workmanship has become an urgent problem in this industry
