Description

Technical Field

[0001] The utility model belongs to the technical field of bearing cages, and specifically relates to a cage for a self-aligning roller bearing with low wear. Background Art

[0002] A self-aligning roller bearing has double rows of rollers, an outer ring with a common spherical raceway, and an inner ring with two raceways inclined at an angle relative to the axis of the bearing. This ingenious structure gives it self-aligning performance, so it is not easily affected by the angular error between the shaft and the bearing housing or shaft bending. The cage is an essential component of the self-aligning roller bearing. At present, the function of the cage is to keep the rollers or balls in the correct positions and guide them to be evenly distributed within the bearing, thus ensuring the normal operation of the bearing. Placing a lubrication structure inside the cage can achieve the function of low wear for the self-aligning roller bearing. However, most cages are integrally formed. When the lubrication structure is damaged, it is difficult to replace or repair it in a timely manner, and the entire cage needs to be replaced subsequently, thus increasing the processing cost. Content of the Utility Model

[0003] In order to overcome the above defects, the utility model provides a cage for a self-aligning roller bearing with low wear, which solves the problem that most cages are integrally formed. When the lubrication structure is damaged, it is difficult to replace or repair it in a timely manner, and the entire cage needs to be replaced subsequently, thus increasing the processing cost.

[0004] To achieve the above object, the utility model provides the following technical solution: A cage for a self-aligning roller bearing with low wear, including a cage body. One side of the cage body is connected with an installation ring, and two installation columns are connected to one side of the cage body. A rotating ring is rotatably connected inside the installation ring, and four arc-shaped plates are connected to the outside of the rotating ring. A bolt is threadedly connected inside the installation column. Four arc-shaped grooves are opened inside the installation ring, a clamping groove is opened inside the installation column, and a threaded hole is opened at one end of the installation column. A sound-absorbing plate is connected inside the cage body, and a lubricating plate is clamped inside the sound-absorbing plate.

[0005] As a further solution of the utility model: The installation column is connected to the arc-shaped plate through the bolt, and the arc-shaped plate is slidably connected inside the arc-shaped groove.

[0006] As a further solution of the utility model: A through hole is opened inside the installation ring, and the installation column is clamped inside the through hole.

[0007] As a further solution of the utility model: The arc-shaped plate is clamped inside the clamping groove, and the bolt is threadedly connected to the threaded hole.

[0008] As a further solution of the utility model: Sound-absorbing plates are respectively arranged on both sides inside the cage body, lubricating plates are arranged inside the sound-absorbing plates, and a number of lubricating sponges are arranged inside the lubricating plates.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] 1. For the cage of the low-wear spherical roller bearing, by providing the mounting posts, arc plates, bolts, rotating rings, card slots and threaded holes, when the mounting ring is connected to the cage body, the mounting posts will penetrate through the through holes. When a rotational force is applied to the rotating ring, the arc plates will slide within the arc grooves, and the arc plates will penetrate through the card slots. When the bolts are threadedly connected to the threaded holes, they will be clamped with the arc plates, enabling the assembly of the mounting ring and the cage body. Through the cooperation among the arc plates, bolts and card slots, the mounting ring and the cage body can achieve the function of rapid assembly. When the lubricating plate is damaged, it can be replaced or repaired in a timely manner, and there is no need to replace the entire cage subsequently, thereby reducing unnecessary processing costs.

[0011] 2. For the cage of the low-wear spherical roller bearing, by providing the sound-absorbing plate and the lubricating sponge, when the cage is operating, the rollers will be connected within the cage body.

Through holes 9 are provided inside the installation ring 2, and the installation columns 3 are clamped in the through holes 9. By providing the through holes 9, when the installation ring 2 is connected to the cage body 1, the installation columns 3 on the side of the cage body 1 will penetrate through the through holes 9, so that the through holes 9 play a certain auxiliary role in fixing the installation ring 2, avoiding the position deviation when the installation ring 2 is connected to the cage body 1;

[0018] A bolt 5 is threadedly connected inside the installation column 3. Four arc-shaped grooves 7 are provided inside the installation ring 2. The installation column 3 is connected to the arc-shaped plate 4 through the bolt 5. The arc-shaped plate 4 is slidably connected in the arc-shaped groove 7. By providing the arc-shaped grooves 7, when a turning force is applied to the rotating ring 6, the rotating ring 6 will drive the arc-shaped plate 4 to slide in the arc-shaped groove 7, so that the arc-shaped grooves 7 play a certain guiding role in the rotation of the arc-shaped plate 4, avoiding the dislocation of the arc-shaped plate 4 during sliding;

[0019] A clamping groove 8 is provided inside the installation column 3, and a threaded hole 10 is provided at one end of the installation column 3. By providing the bolt 5, when the installation ring 2 is connected to the cage body 1, it will be threadedly connected to the two installation columns 3 through the two bolts 5. The two bolts 5 can disperse the load of the fixing points, reduce the burden on a single bolt 5, and thus reduce the risk of damage to the bolt 5 due to excessive load;

[0020] Sound-absorbing plates 11 are respectively provided on both sides inside the cage body 1. A lubricating plate 12 is provided inside the sound-absorbing plate 11. A number of lubricating sponges 13 are provided inside the lubricating plate 12.

When the rollers rotate inside the cage body 1, the lubricating sponges 13 inside the lubricating plate 12 will lubricate their surfaces, and the sound-absorbing plates 11 will absorb the noise generated by the rollers.

[0021] The working principle of the present utility model is as follows:

[0022] When the cage is in use, the lubricating plate 12 can be inserted into the cage body 1, and the lubricating plate 12 will be clamped inside the sound-absorbing plate 11. Then the installation ring 2 is connected to the cage body 1. The installation columns 3 on the side of the cage body 1 will penetrate through the through holes 9. When a turning force is applied to the rotating ring 6, the arc-shaped plate 4 will slide in the arc-shaped groove 7, and the arc-shaped plate 4 will penetrate through the clamping groove 8. When the bolt 5 is threadedly connected to the threaded hole 10, it will be clamped to the arc-shaped plate 4, so that the installation ring 2 and the cage body 1 can be assembled.
