Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a technical solution: a bearing for a hinge point of a swing arm loader frame which is easy to lubricate, comprising an outer ring 1, an inner ring 2 is arranged inside the outer ring 1, and a plurality of groups of balls 3 are arranged between the outer ring 1 and the inner ring 2, the inner ring 2 is inserted on a rotating shaft 4, and an oil storage groove 5 is placed below the rotating shaft 4, a first fixing plate 6 is placed on the outer side of the rotating shaft 4, and a spiral groove is opened on the rotating shaft 4 below the first fixing plate 6, a screw 7 is spirally arranged in the spiral groove, and the screw 7 is spirally arranged on the first fixing plate 6, and a fixing frame 8 is provided on the upper end surface of the first fixing plate 6.

[0020] Furthermore, the fixing frame 8 is screwed in the spiral groove through the first fixing plate 6 and the screw 7 to form a spiral locking structure with the rotating shaft 4, so that the subsequent installation of the lubrication and cleaning components is facilitated by the spirally installed fixing frame 8, and then the subsequent lubrication of the bearing is facilitated.

[0021] The fixing frame 8 is provided with a first connecting block 9 and a second connecting block 12 at the upper end thereof, and elastic limit blocks 10 are provided on the outer walls on both sides of the first connecting block 9 and the second connecting block 12, respectively. Limiting holes are provided on both sides of the fixing frame 8, and the elastic limit blocks 10 are inserted into the limiting holes. A scraper 11 is provided on the first connecting block 9, and a second fixing plate 13 is provided on the second connecting block 12, and a brush 14 is provided on the side of the second fixing plate 13 close to the ball 3.

[0022] Furthermore, the scraper 11 and the brush 14 are respectively inserted between the inner ring 2 and the outer ring 1, and the first connecting block 9 and the second connecting block 12 are respectively inserted in the limiting hole through the elastic limiting block 10 to form an elastic locking limiting structure with the fixing frame 8, so that the scraper 11 can be used to clean the inside of the bearing before lubrication, and the brush 14 can be used during lubrication to ensure that the lubricating oil is evenly applied to the bearing.

[0023] A nozzle 15 is correspondingly disposed on one side of the brush 14 on the second fixing plate 13 , and a connecting pipe 16 is disposed on the nozzle 15 , and the other end of the connecting pipe 16 is connected to the oil storage tank through an oil pump.

[0024] Furthermore, the nozzle 15 forms a communication structure with the liquid storage tank through the connecting pipe 16 under the action of the oil pump, so that the nozzle 15 can be replaced to lubricate the bearing when the bearing speed is fast, thereby facilitating the selection of a suitable lubrication method according to the bearing speed.

[0025] Working principle: When using a bearing for the hinge point of a boom loader frame that is easy to lubricate, first, if the bearing rotates slowly, an oil reservoir 5 can be placed under the bearing, so that the bearing can be lubricated in an oil bath through the oil reservoir 5. Before oil bath lubrication, the first fixing plate 6 can be screwed onto the rotating shaft 4 through the screw 7, and the scraper 11 can be snap-fitted onto the fixing frame 8 through the elastic limit block 10, so that the inside of the bearing can be roughly cleaned through the scraper 11, thereby ensuring the subsequent lubrication effect of the bearing; after the bearing is cleaned, the elastic limit block 10 can be pressed to remove the scraper 11, so that the running bearing can be lubricated in an oil bath; if If the bearing rotates at a faster speed, a nozzle 15 can be selected to lubricate it. After the bearing is cleaned, the second fixing plate 13 is clamped and installed on the fixing frame 8 through the elastic limit block 10. The lubricating oil in the oil storage tank enters the nozzle 15 through the connecting pipe 16 under the action of the oil pump, so that the inside of the bearing can be sprayed in all directions through the nozzle 15. At the same time, the brush 14 works inside the bearing to ensure that the lubricating oil after spraying can be evenly applied to the bearing, so as to facilitate the selection of a suitable lubrication method according to the bearing rotation speed, and at the same time ensure the lubrication effect of the bearing. This is the use process of the bearing for the hinge point of the swing arm loader frame that is easy to lubricate.
