Abstract
Description
Technical Field
[0001] This utility model relates to the field of papermaking technology, specifically to a perforated wheel with spokes. Background Technology
[0002] In various papermaking machinery, the paper-feeding rope wheel is an indispensable and crucial piece of equipment. Existing technology (Chinese patent application number CN201810855233.8, published April 10, 2020) describes a paper-feeding rope wheel device. This device is fixedly mounted on a support shaft and includes a main shaft, a bearing, and a rope wheel body. The main shaft has a first end and a second end. The bearing is sleeved on the first end of the main shaft, and its inner ring is fixedly connected to the main shaft. The rope wheel body is sleeved on the second end of the main shaft and fixedly connected to it, allowing the rope wheel body, the main shaft, and the inner ring of the bearing to rotate synchronously, while the outer ring of the bearing remains stationary. This method reduces the centrifugal force on the lubricating oil, effectively preventing the lubricating oil from being thrown off, ensuring sufficient lubricating oil for the bearing, and thus effectively extending the bearing's service life.
[0003] The original papermaking rope wheel had no holes in its spokes, which increased the weight of the rope wheel and caused poor heat dissipation. The long-term operation of the rope wheel in the high-temperature environment of the drying section caused problems such as loosening and wear of the tight fit between the outer ring of the bearing and the bearing hole wall inside the rope wheel bearing hole. In addition, the connection between the rope wheel and the bearing is generally an integral part, making it inconvenient to replace the worn rope wheel separately. Utility Model Content
[0004] The purpose of this utility model is to provide a perforated spoke sheave to solve the problems mentioned in the background art, such as the lack of perforations in the spokes of the original papermaking sheave, which increases the weight of the sheave itself and causes poor heat dissipation. Long-term operation of the sheave in the high-temperature environment of the drying section leads to loosening and wear of the tight fit between the outer ring of the bearing and the bearing hole wall in the sheave bearing hole. In addition, the connection between the sheave and the bearing is generally an integral part, making it inconvenient to replace the worn sheave separately.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spoked perforated rope pulley, comprising a rope pulley body, a spoked body fixed to the inner side of the rope pulley body, a bearing connected to the middle of the spoked body, and a mounting shaft connected to the middle of the bearing, through holes uniformly formed on the surface of the spoked body, the through holes being designed to be through-holes within the spoked body, a connecting block provided on the outer side of the bearing, a connecting groove provided on the inner side of the spoked body, and the connecting groove and the connecting block forming a front-to-back sliding structure, enabling stable transmission between the spoked body and the bearing, and a positioning mechanism provided on the outer side of the connecting block to position the connection between the connecting block and the connecting groove.

[0007] To further optimize this technical solution, a connecting mechanism is provided between the connecting block and the bearing, and the connecting block is connected to the outer ring of the bearing through the connecting mechanism.
[0008] To further optimize this technical solution, the connecting mechanism is composed of a fitting sleeve, which is sleeved on the outside of the bearing and is made of rubber. The fitting sleeve and the main body of the spoke plate form a nested connection.
[0009] To further optimize this technical solution, the positioning mechanism includes a positioning ring and an installation mechanism;
[0010] The positioning ring is fixed to the rear side of the connecting block to restrict the installation position of the rear end of the spoke body;

[0017] A connecting groove extends through the interior of the connector and the mounting ring;
[0018] The mounting rod passes through the connecting groove, and the front end of the mounting rod has an enlarged structural design.
[0019] The mounting groove is formed inside the connecting block, and the mounting groove and the mounting rod form a threaded connection.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] (1) By evenly opening multiple through holes around the circumference of the main body of the spoke plate, the weight of the main body of the rope wheel is reduced, the load on the bearing is reduced, and the through holes can improve the ventilation and heat dissipation effect, effectively reduce the temperature of the bearing during operation, and extend the service life of the rope wheel.
[0022] (2) The main body of the spoke plate is installed by setting a connecting block on the outside of the bearing and the connecting groove on the main body of the spoke plate. The spoke plate is installed by insertion, which is convenient and quick.

A connecting block 7 is provided on the outer side of the bearing 3, and a connecting groove 9 is provided on the inner side of the spoke body 2. The connecting groove 9 and the connecting block 7 form a sliding structure, enabling stable transmission between the spoke body 2 and the bearing 3. A positioning mechanism is provided on the outer side of the connecting block 7 to position the connection between the connecting block 7 and the connecting groove 9.
[0034] When in use, the main body 1 of the rope wheel can rotate outside the bearing 3. Without affecting the strength of the rope wheel spokes, when processing the main body 1 of the rope wheel, multiple through holes 5 are evenly opened along the circumferential direction of the spoke body 2 and a dynamic balance test is performed. Subsequently, the setting of through holes 5 can reduce the overall weight of the device and improve the heat dissipation effect.
[0035] Example 2: Based on Example 1, as follows Figure 4-5 As shown, the connecting blocks 7 are distributed at equal angles on the outer side of the bearing 3. The connecting grooves 9 and the connecting blocks 7 are arranged in a one-to-one correspondence. The front and rear ends of the connecting grooves 9 are designed with an open structure. A connecting mechanism is provided between the connecting blocks 7 and the bearing 3. The connecting blocks 7 are connected to the outer ring of the bearing 3 through the connecting mechanism. The connecting mechanism is composed of a fitting sleeve 6. The fitting sleeve 6 is fitted on the outer side of the bearing 3. The fitting sleeve 6 is made of rubber material. The fitting sleeve 6 and the spoke body 2 form a nested connection.
[0036] The connecting block 7 is installed on the outer ring of the bearing 3 through the fitting sleeve 6 without affecting the original structure of the bearing 3. The processing difficulty is low. The connecting block 7 is connected to the spoke body 2 through the connection and cooperation with the connecting groove 9. It can be removed and replaced separately later.
[0037] Example 3: Based on Example 1, as follows Figure 6-8As shown, the positioning mechanism further discloses a positioning ring 8 and an installation mechanism.

The locking mechanism is set to the front side of the positioning ring 8 to lock the connection between the installation ring 10 and the connecting block 7. The locking mechanism includes a connecting groove 12, an installation rod 13, and an installation groove 14. The connecting groove 12 passes through the interior of the coupling 11 and the installation ring 10. The installation rod 13 passes through the connecting groove 12 and has an enlarged front end. The installation groove 14 is opened inside the connecting block 7, and the installation groove 14 and the installation rod 13 form a threaded connection.
[0038] When installing the spoke body 2, insert the connecting groove 9 into the outside of the connecting block 7 so that the rear end of the spoke body 2 and the positioning ring 8 fit together. Then, install the mounting ring 10 into the front of the connecting block 7, insert the connector 11 into the inside of the connecting block 7, insert the mounting rod 13 into the connecting groove 12, rotate the mounting rod 13 to connect it with the mounting groove 14, and fix the mounting ring 10 so that the mounting ring 10 and the positioning ring 8 can limit the position of the spoke body 2.
