Problems solved by technology
When the lubricating oil pipe is used to provide lubrication for the transmission box, the structure of the oil injection hole has a significant impact on the lubrication effect. However, the circular oil injection hole used in the prior art has a limited range of spraying, resulting in a poor lubrication effect in the gearbox. not ideal

The invention provides a lubricating pipe. The lubricating pipe comprises a pipe wall part, oil spraying holes and oil outlet grooves. A cavity part for circulating lubricating oil is defined by the pipe wall part; the oil spraying holes are formed in the pipe wall part at intervals in the axial direction of the lubricating pipe, and lubricating oil flows out of the oil spraying holes; and the oil outlet grooves are formed in the peripheries of the oil spraying holes, each oil outlet groove comprises a first inclined face and a second inclined face which are arranged in an inclined mode and intersect, and the lubricating oil flows out of the oil spraying holes and then is diffused out through the first inclined faces and the second inclined faces to achieve the lubricating effect. According to the lubricating oil holes, the lubricating area of the lubricating oil can be increased, and then the lubricating effect on gears and bearings in a gearbox is enhanced.
Description
technical field [0001] The invention relates to the technical field of transmission boxes, and in particular provides a transmission box with lubricating oil pipes. Background technique [0002] The transmission box generally contains a large number of friction pairs such as gears and bearings. During operation, the friction pairs such as gears and bearings will generate a lot of heat. Generally, a lubrication system needs to be designed. On the one hand, the lubrication system provides lubrication for gears and bearings, and on the other hand, it takes away the heat generated during the operation of gears and bearings. In the existing gearboxes, a lubricating oil pipe with multiple circular oil spray holes is often used to provide lubrication for the transmission case, and the lubricating oil is sprayed to the positions requiring lubrication through the oil spray holes. When the lubricating oil pipe is used to provide lubrication for the transmission box, the structure of ...
