[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic structural diagram of the belt layer ring provided by the present invention.

[0024] The belt ring provided by the present invention comprises a circular left side plate 1, a right side plate 2 and a plurality of rib plates 4. Figure 1 As shown, the left side plate 1 and the right side plate 2 are coaxially arranged, the rib plate 4 is located between the left side plate 1 and the right side plate 2, and all the rib plates 4 are located in the same circle coaxial with the left side plate 1 and are evenly distributed along the circumference. All the rib plates 4 have the same length, and both ends are fixedly connected to the left side plate 1 and the right side plate 2, respectively, so as to support the left side plate 1 and the right side plate 2.

[0025] The left side plate 1, the right side plate 2 and the rib plate 4 are formed into an integrally formed structural member by welding, casting or the like, and the three together form a ring body for mounting the drive ring assembly 3. Among them, the inner hole of the left side plate 1 is a mounting hole 11, and the diameter of the mounting hole 11 is larger than that of the drive ring assembly 3. The drive ring assembly 3 is inserted between the left side plate 1 and the right side plate 2 through the mounting hole 11.

[0026] In addition, a plurality of support shaft assemblies 5 are provided between the left side plate 1 and the right side plate 2. The support shaft assemblies 5 include support shafts and support bearings 51 sleeved on the outer periphery of the support shafts. The support shaft assemblies 5 are located on the outer periphery of the drive ring assembly 3, and the bearings on the support shaft assemblies 5 fit the outer periphery of the drive ring assembly 3, thereby supporting the drive ring assembly 3. In other words, the diameter of the circle surrounded by the innermost points of all the support bearings 51 is less than or equal to the outer diameter of the drive ring assembly 3.

[0027] Furthermore, the outer periphery of the driving ring assembly 3 is provided with a positioning groove extending in the circumferential direction, and all the support bearings 51 can be embedded in the positioning groove, thereby limiting the axial position of the driving ring assembly 3. That is, the diameter of the circle surrounded by the innermost points of all the support bearings 51 is smaller than the outer diameter of the driving ring assembly 3.

[0028] In addition, the left side plate 1 is provided with a light hole penetrating in the thickness direction, and the light holes are evenly distributed along the axial direction of the left side plate 1. The right end surface of the right side plate 2 is provided with a threaded hole corresponding to the position of the light hole, and the end of the support shaft is provided with an external thread. The support shaft assembly 5 is installed in the light hole, and the two are clearance-matched. During the assembly process, the support shaft assembly 5 at the lower part of the ring body is first installed. Specifically, the support shaft passes through the light hole, and then a support bearing 51 is sleeved on the outer periphery of the support shaft, and then the support shaft is pushed to the left to connect it with the threaded hole on the right side plate 2. After completing the installation of the support shaft assembly 5 at the lower part of the ring body, the drive ring assembly 3 is installed into the ring body through the mounting hole 11, and the support bearing 51 is placed in the limit groove, and then the remaining support shaft assemblies 5 are installed.

[0029] In this embodiment, the ring body formed by the left side plate 1, the right side plate 2 and the rib plate 4 is an integrally formed structural part, which has high strength and can withstand large axial and radial forces, thereby reducing the vibration of the belt ring during operation. At the same time, the gap between the integrally formed structural parts is small, and the positioning accuracy of the ring body is high; and its structure is simple, with fewer parts, which can reduce the difficulty of assembly and thus reduce the manufacturing cost.

[0030] Optionally, in order to limit the range of movement of the right end of the support shaft, an expansion sleeve 12 is further provided between the support shaft and the light hole. The expansion sleeve 12 can be specifically a rubber expansion sleeve, which is interference fit with the support shaft and the light hole. When the support shaft is subjected to shear force, the expansion sleeve 12 can play a buffering role, absorb the vibration generated during operation, and further reduce the vibration of the belt layer ring. In addition, in order to prevent the expansion sleeve 12 from falling off during operation, the expansion sleeve 12 is fixedly connected to the left side plate 1 by fastening bolts.

[0031] The belt layer ring also includes a base 6 located at the lower part of the ring body and arranged in the horizontal direction. The ring body is located above the base 6 and arranged in the vertical direction. The lower parts of the left side plate 1 and the right side plate 2 are both provided with a connecting part, such as Figure 1 As shown, the side of the connecting portion is tangent to the outer periphery of the left plate 1 or the right plate 2, and extends downward in a wedge shape. The lowermost end of the connecting portion is a horizontal side, and the horizontal side is in contact with the base 6. In this embodiment, the two connecting portions are welded and fixed to the base 6, so that the ring body and the base 6 form an integrally molded structural member, further improving the strength of the belt layer ring.

[0032] In addition, four reinforcing ribs are provided between the base 6 and the connecting portion, and two reinforcing ribs are connected to each connecting portion. Figure 1 As shown, the reinforcing rib is triangular, and its side surface is parallel to the side edge of the connecting portion on one side thereof, and is perpendicular to the plane where the connecting portion is located. The reinforcing rib is also fixedly connected to the connecting portion and the base 6 by welding.

[0033] In this embodiment, the ring body, the base 6 and the reinforcing ribs are welded into an integrally formed structural part, so that the strength of the belt ring is further improved. The driving ring assembly 3 generates axial force and radial force during the rotation of the ring body. The improved strength of the belt ring can reduce the vibration during the force-bearing process, and can improve the installation accuracy and reduce the difficulty of assembly. In addition, the right end of the support shaft is supported by the expansion sleeve 12, which can absorb the vibration during the operation, further reduce the vibration of the belt ring, avoid its mechanical damage, and extend the service life of the belt ring.

[0034] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0035] The belt ring provided by the present invention is introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the present invention. The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
