[0002] Bevel gears, that is, conical gears, are used for transmission between intersecting shafts. They are divided into straight bevel gears and spiral bevel gears. Helical bevel gears have smooth transmission and high gear load-bearing capacity, but are difficult to manufacture and are less used. Curved bevel gears have the characteristics of smooth transmission, low noise and large load-bearing capacity. They are used in high-speed and heavy-load situations. Curved bevel gears have smooth transmission, but the gears are transmitted through meshing. During the meshing process, the gears will wear, thereby reducing the life of the gears. Therefore, the gears need to be lubricated, but the current bevel gears can only be lubricated by adding lubricating oil externally and cannot be self-lubricated, resulting in frequent manual replenishment of lubricating oil, which increases a lot of maintenance time and costs.

[0037] In this embodiment, in order to achieve the quantitative storage effect of lubricating oil, a filling control component 5 is designed. Side grooves 5-1 are provided on both sides of the filling groove 3, and only a rotating groove 5-2 is provided inside. An adjusting screw 5-3 is rotatably connected in the rotating groove 5-2, and a closing cover 5-4 is connected to the outside of the adjusting screw 5-3 through threaded cooperation, which is used to cover the filling groove 3.
