Problems solved by technology

However, in the process of gear lubrication, the amount of splashing lubricating oil caused by low liquid level is often insufficient. In order to increase the amount of splashing lubricating oil, oil scraping plates or oil scraping blocks are generally installed in the gear box in the prior art, but scraping The amount of oil that can be supplied by the oil plate or oil scraper block is very limited, and the assembly accuracy is very high
In addition to setting the oil scraper or oil scraper block, you can also cast or machine the oil collecting groove in the inner cavity of the gearbox, and use the oil collecting groove to collect the splashed lubricating oil, but the oil collecting groove increases the difficulty of casting or machining of the gearbox , and the oil quantity of the splash lubricating oil is also very limited
[0003] In order to increase the amount of splashing lubricating oil, it is necessary to increase the oil level of the gearbox, but if the oil level is too high, it will increase the churning loss of the gearbox and reduce the transmission efficiency of the gearbox. In addition, it will also increase the leakage at the mechanical seal of the gearbox. oil risk

Abstract

The invention discloses a gearbox and belongs to the technical field of gearbox lubrication. The gearbox provided by the invention comprises a lubricating oil pool formed in the inner bottom of the gearbox and oil stirring boxes. Each oil stirring box comprises an oil storage cavity, wherein an oil excavation port and oil outlets are formed in the oil storage cavity. The oil stirring boxes are arranged on a rotating component inside the gearbox and can be configured to be immersed in the lubricating oil pool as the rotating component rotates. According to the gearbox provided by the invention,by arranging the oil stirring boxes on the rotating component, lubricating oil in the lubricating oil pool is transported to a high position by means of the oil stirring boxes, and accordingly, the purpose that the lubricating effect of a lubricating point of the gearbox is improved on the premise that the transmission efficiency of the gearbox is not affected can be achieved.

Description

technical field [0001] The invention relates to the technical field of gearbox lubrication, in particular to a gearbox. Background technique [0002] The gearbox is an important part widely used in mechanical transmission, and the gear is the basic part in the transmission of the gearbox. In order to reduce the friction generated during the gear meshing process, it is often necessary to use gear lubricating oil to lubricate the gears. However, in the process of gear lubrication, the amount of splashing lubricating oil caused by low liquid level is often insufficient. In order to increase the amount of splashing lubricating oil, oil scraping plates or oil scraping blocks are generally installed in the gear box in the prior art, but scraping The amount of oil that can be supplied by the oil plate or oil scraper block is very limited, and the assembly accuracy is very high. In addition to setting the oil scraper or oil scraper block, you can also cast or machine the oil colle...
