[0037] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0038] Embodiment:

[0039] See Figure 1 、 Figure 2 and Figure 3 , this embodiment discloses a split bearing, including a half inner ring 11, a half rotor 21, a half retaining sleeve 31 and a half outer ring 41. And there are two of each of the half inner ring 11, the half rotor 21, the half retaining sleeve 31 and the half outer ring 41. The two half inner rings 11 are combined to form a complete inner ring 10, the two half rotors 21 are combined to form a complete rotor 20, the two half retaining sleeves 31 are combined to form a complete retaining sleeve 30, and the two half outer rings 41 are combined to form a complete outer ring 40.

[0040] Specifically, after the two half inner rings 11 form a circular complete inner ring 10, two half rotors 21 are installed on the outer surface of the complete inner ring 10. The two half rotors 21 are respectively clamped on the complete inner ring 10 from both sides of the complete inner ring 10. After forming the complete rotor 20, it is installed in the middle of the complete inner ring 10.

[0041] The two half retaining sleeves 31 are also respectively clamped on the complete inner ring 10 from both sides of the complete inner ring 10. After forming a complete retaining sleeve 30, it is installed at the end of the complete inner ring 10 so as to abut against one end of the complete rotor 20. In addition, in this application, the two complete retaining sleeves 30 are respectively arranged at both ends of the complete inner ring 10, so that both ends of the complete rotor 20 respectively abut against the two complete retaining sleeves 30, thereby restricting the complete rotor 20 in the middle of the complete inner ring 10 through the two complete retaining sleeves 30.

[0042] Finally, the two half outer rings 41 are respectively sleeved outside the complete rotor 20 from both sides of the complete rotor 20, and the two half outer rings 41 are connected to form a complete inner ring 10, thus completing the assembly of the entire split bearing.

[0043] During the installation process, first, the two half inner rings 11 are clamped onto the shaft from both sides of the shaft. Then, the two half inner rings 11 are connected to form a complete inner ring 10. Next, the two half rotors 21 and the half sleeves 31 are respectively clamped outside the complete inner ring 10 to form a complete rotor 20 and a complete sleeve 30. Finally, the two half outer rings 41 are sleeved outside the complete rotor 20, thereby installing the entire bearing onto the shaft completely.

[0044] Compared with the prior art, the split bearing in this embodiment can be installed on the outer surface of a shaft with any structure.

[0045] In one specific embodiment:

[0046] One end of one of the half sleeves 31 is provided with a bolt through-hole 32, and the end of the other half sleeve 31 is provided with a bolt counterbore 33. The axis of the bolt through-hole 32 is perpendicular to the end of the half sleeve 31, and the axis of the bolt through-hole 32 is also perpendicular to the axis of the complete sleeve 30.

[0047] After the two half sleeves 31 form the complete sleeve 30, the bolt through-hole 32 and the bolt counterbore 33 are coaxially distributed, and a bolt (not shown in the figure) is fitted in the bolt through-hole 32 and the bolt counterbore 33.

[0048] Among them, both ends of the half sleeve 31 having the bolt through-hole 32 are provided with bolt through-holes 32. Similarly, both ends of the other half sleeve 31 are provided with bolt counterbores 33. By matching the two bolt through-holes 32 with the two bolt counterbores 33 and respectively fitting a bolt inside, the fixed connection of the two half sleeves 31 is realized, so that they form a complete sleeve 30.

[0049] Preferably, the end of the half sleeve 31 provided with the bolt counterbore 33 is further provided with an observation hole 34. The observation hole 34 penetrates out of the outer side surface of this half sleeve 31 from the end of the bolt counterbore 33, so that the inside of the end of the bolt counterbore 33 far from the bolt through-hole 32 can be seen through the observation hole 34.

[0050] By providing the observation hole 34, the tightening condition of the bolt in the bolt through-hole 32 and the bolt counterbore 33 can be observed, thereby judging the connection condition between the two half sleeves 31.

[0051] In another specific embodiment:

[0052] One end of one of the half inner rings 11 and one end of one of the half sleeves 31 are respectively provided with a positioning groove 12. When the half sleeve 31 is installed onto the complete inner ring 10, the positioning groove 12 on the half inner ring 11 and the positioning groove 12 on the half sleeve 31 are aligned. Then, a positioning block 13 is clamped in the two positioning grooves 12, so that both ends of the positioning block 13 are respectively clamped in the two positioning grooves 12, thereby realizing the positioning between the complete sleeve 30 and the half inner ring 11.

[0053] It should be noted that generally, the connection positions of the two semi-inner rings 11 and the connection positions of the two semi-ferrules 31 are distributed in a staggered state. Thus, one semi-ferrule 31 can wrap the connection part of the two semi-inner rings 11 to improve the structural stability.

[0054] In another specific embodiment:

[0055] The semi-rotor 21 includes a mounting ring 211 and rollers 212, and the rollers 212 are rotatably mounted on the mounting ring 211. Specifically, the mounting ring 211 is a semi-circular structure, and a plurality of mounting grooves 213 are provided on the mounting ring 211. The mounting grooves 213 are strip-shaped, and the length direction is consistent with the axial direction of the semi-rotor 21. Among them, the mounting grooves 213 penetrate through the inner and outer sides of the mounting ring 211.

[0056] One roller 212 is rotatably provided in each mounting ring 211. The roller 212 is a cylindrical structure, and the axis of the roller 212 is parallel to the axis of the semi-rotor 21. And both sides of the roller 212 protrude from the inner and outer sides of the semi-rotor 21 respectively.

[0057] In this embodiment, after the two semi-rotors 21 form the complete rotor 20, the mounting ring 211 provides a stable support for the roller 212 and enables the roller 212 to roll between the complete inner ring 10 and the complete outer ring 40. In addition, the aforementioned two complete ferrules 30 are respectively abutted against the top and bottom of the mounting ring 211.

[0058] Preferably, the two mounting rings 211 are butted to form a complete ring structure. A connection groove 214 is provided at each end of the two mounting rings 211 that are butted against each other. Both ends of a connection block 215 are respectively provided in the two connection grooves 214 of the two mounting rings 211. Two threaded holes are provided in the connection groove 214 at the end of the mounting ring 211. The four threaded holes on the connection block 215 are staggeredly distributed, and the threaded holes at the end of the mounting ring 211 are arranged corresponding to the threaded holes on the connection block 215.

[0059] The two mounting rings 211 are butted through the connection block 215. The staggeredly distributed threaded holes facilitate the installation of more screws (not shown in the figure) on the smaller connection block 215, thereby improving the connection stability.

[0060] In another specific embodiment:

[0061] A clamping groove 42 is provided on the outer surface of the semi-outer ring 41, and the two semi-outer rings 41 are detachably connected by a clamping plate 43. Specifically, a clamping groove 42 is provided at each end of the same semi-outer ring, and a clamping plate 43 is installed on the clamping grooves 42 at both ends of the two semi-outer rings 41 through a plurality of screws, and the two semi-outer rings 41 are connected by the clamping plate 43 to form a complete annular outer ring 40.

[0062] The above embodiments only express the specific implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
