[0003] As a key component of the reducer, the operating status of the bearing directly affects the performance and service life of the reducer. The traditional bearing lubrication method is that people manually pour the lubricating oil directly into the bearing, so that the lubricating oil adheres to the bearing. Since the bearing is composed of an inner ring, an outer ring and multiple balls, it is necessary to find the oil dripping point for injection multiple times, which is cumbersome and prone to uneven lubrication, so that the lubricating oil cannot better penetrate into the tiny gaps between the components.

[0024] Embodiment 1
[0025] Combined with Figure 1 and attached Figure 2 A lubrication structure for a reducer bearing includes an oil storage barrel 1, the top end of the oil storage barrel 1 is covered with a cover 2, the bottom end of the oil storage barrel 1 is provided with a plurality of oil pipes 7 connected to the oil storage barrel 1, the ends of the oil pipes 7 are provided with stretchable bellows 8, and the bottom ends of the bellows 8 are provided with oil outlet pipes 9.
[0026] Through the above structure, the oil storage barrel 1 is held so that the oil outlet pipes 9 are all located on the reducer bearings. The lubricating oil is poured into the oil storage barrel 1. The lubricating oil can be directly dripped into the bearings through multiple oil outlet pipes 9, and the refueling efficiency is high.
[0027] Combined with Figure 2 The connection between the cover 2 and the oil storage barrel 1 is a threaded connection. Anti-slip grooves 17 are provided on both sides of the oil storage barrel 1. Anti-slip grooves 17 are provided on both sides of the oil storage barrel 1. The oil delivery pipe 7 is evenly distributed at the bottom end of the oil storage barrel 1, and a sealing plug is inserted at the bottom end of the oil outlet pipe 9.
[0028] Through the above structure, the connection between the cover 2 and the oil storage barrel 1 is a threaded connection, which is easy to open and pour lubricating oil into the oil storage barrel 1. The anti-slip grooves 17 on both sides of the oil storage barrel 1 are convenient for holding and rotating the oil storage barrel 1, so that the lubricating oil is evenly attached to the bearing.
[0029] Embodiment 2
[0030] Combined with Figure 4 A threaded stud 10 is provided on one side of the oil outlet pipe 9, a fixed plate 11 is provided on one side of the stud 10, a movable column 12 is inserted on the fixed plate 11, a baffle 13 is provided on the top of the movable column 12, a spring 14 is provided on the movable column 12 between the baffle 13 and the fixed plate 11, a cleaning plate 15 is provided at the bottom end of the movable column 12, and a brush 16 is provided at the bottom end of the cleaning plate 15.
[0031] Through the above structure, the brush 16 can move slightly up and down under the action of the elastic force of the spring 14, and the brush 16 is covered with lubricating oil, which ensures that the lubricating oil is evenly distributed on the surface of the parts that need lubrication during the sweeping movement, and allows the lubricating oil to better penetrate into the tiny gaps between the parts.
[0032] Combined with Figure 3 and attached Figure 5 A filter screen 3 is provided in the oil storage barrel 1, and concave slide grooves 4 are provided on both sides of the inner wall of the oil storage barrel 1.

[0037] Then, during the rotation of the oil storage barrel 1, the brush 16 moves along and can evenly apply the lubricating oil to the bearing. Since there are balls in the bearing with different heights, the brush 16 moves slightly up and down under the action of the elastic force of the spring 14, injecting lubricating oil while scraping, which not only ensures that the lubricating oil is evenly distributed on the surface of the components, but also allows the lubricating oil to better penetrate into the tiny gaps between the components, making it easy to use.
