Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a sprocket that facilitates the disassembly of bearings. Background Technology

[0002] A bearing sprocket typically refers to a sprocket assembly that integrates or links a bearing system. This design is primarily used to simplify installation, improve alignment accuracy, and facilitate maintenance. In many mechanical transmission systems, sprockets and bearings are two independent but closely related components that work together to ensure efficient power transmission.

[0003] However, in existing technologies, most sprockets and bearings are fixedly connected, making disassembly inconvenient and hindering independent replacement or maintenance. This reduces the effectiveness of bearing and sprocket maintenance. Furthermore, traditionally disassembled bearings are mostly split-type, dividing the bearing into two halves. While this facilitates disassembly, the structural strength of split bearings is reduced, making them prone to localized wear, which reduces bearing lifespan and increases maintenance costs. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the existing technology, most sprockets and bearings are fixedly connected, making disassembly inconvenient and hindering independent replacement or maintenance. This reduces the effectiveness of bearing and sprocket maintenance. Furthermore, traditionally disassembled bearings are mostly split-type, dividing the bearing into two halves. While this facilitates disassembly, the structural strength of split bearings is reduced, making them prone to localized wear, which reduces bearing lifespan and increases maintenance costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sprocket for easy disassembly of bearings, comprising: a bearing body and a sprocket body, and further comprising:

[0009] A positioning component is disposed on one side of the annular plate.

[0010] Preferably, the splicing component further includes:

[0011] A rectangular groove is formed on one side of the positioning plate, and two limiting grooves are formed inside the rectangular groove;

[0012] Among them, the two limiting grooves are symmetrical;

[0016] The technical effect of adopting the above-mentioned further solution is that the positioning plate is embedded inside the slot, and the positioning pin is embedded inside the limiting hole under the elastic force of the spring, so that the positioning plate is more stably embedded inside the slot, thereby connecting the bearing body and the sprocket body. A rectangular block is installed on one side of the positioning pin, which can improve the stability of the positioning pin.

[0017] Preferably, the positioning component includes:

[0018] A circular plate is movably disposed on one side of the annular plate. Multiple connecting blocks are fixedly disposed on the outer surface of the circular plate.

[0023] The technical effect of adopting the above-mentioned further solution is that the two sliders fixedly installed on the outer surface of the rectangular block can slide inside the limiting groove, which can not only improve the stability of the rectangular block, but also prevent the rectangular block from falling out of the rectangular groove.

[0024] Preferably, a spring is fixedly provided on one side of the slider, and the other end of the spring is fixedly provided inside the limiting groove near the through hole.

[0025] The technical effect of adopting the above-mentioned further solution is that the positioning pin is embedded inside the limiting hole under the elastic force of the spring.

[0026] Preferably, the card slot has two limiting holes inside;

[0027] The locating pin passes through the through hole and is embedded inside the limiting hole.

[0028] The technical effect of adopting the above-mentioned further solution is that the positioning pin is embedded in the limiting hole under the elastic force of the spring, so that the positioning plate is more stably embedded in the slot, thereby connecting the bearing body and the sprocket body.

[0029] Preferably, two locking blocks are fixedly provided on one side of the annular plate, and the two locking blocks are symmetrical to each other;

[0030] The card block is set inside the rectangular slot.

[0031] The technical effect of adopting the above-mentioned further solution is that the card block is embedded into the inside of the rectangular groove by the ring plate. The card block can position the rectangular block and hold it against the rectangular block so that it drives the positioning pin to be more stably embedded in the limiting hole, thus preventing the rectangular block from sliding.

A rectangular block is installed on one side of the positioning pin. The rectangular block can improve the stability of the positioning pin, so that it can better drive the positioning pin through the through hole and then embed into the limiting hole. Two sliders fixedly installed on the outer surface of the rectangular block can slide inside the limiting groove, which can not only improve the stability of the rectangular block, but also prevent the rectangular block from falling out of the rectangular groove. When disassembling, simply pull the rectangular block to drive the positioning pin and move it out of the limiting hole. Disassembly is convenient and quick.

[0034] 2. In this utility model, the locking block is embedded into the rectangular groove by the circular ring plate.

Detailed Implementation

[0041] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0043] Example 1, such as Figure 1-4 As shown, this utility model provides a sprocket with an easy-to-disassemble bearing, including: a bearing body 1, a sprocket body 102, a splicing assembly, and a positioning assembly;

[0044] The splicing assembly includes: two positioning plates 106 are fixedly installed on the outer surface of the bearing body 1. The two positioning plates 106 are symmetrical. A rectangular groove 113 is opened on one side of the positioning plate 106. Two limiting grooves 114 are opened inside the rectangular groove 113. A through hole 115 is opened on the side of the positioning plate 106 near the rectangular groove 113.

[0045] The through hole 115 is connected to the rectangular groove 113, which facilitates the positioning pin 119 to pass through the through hole 115 and be embedded in the interior of the limiting hole 108.

[0046] A rectangular block 116 is movably embedded inside the rectangular groove 113. A positioning pin 119 is fixedly installed on one side of the rectangular block 116 and is movably embedded inside the through hole 115. Two sliders 117 are fixedly installed on the outer surface of the rectangular block 116.

[0047] The slider 117 can slide laterally inside the limiting groove 114;

[0048] Spring 118 is fixedly connected to one side of slider 117, and the other end of spring 118 is fixedly connected to the inside of limiting groove 114 near through hole 115;

[0049] The annular plate 101 is fixedly installed on the inner surface of the sprocket body 102. Two slots 107 are opened on the inner surface of the annular plate 101. The two slots 107 are symmetrical. A limiting hole 108 is opened on one side of the inside of the slot 107.

[0050] In this embodiment, the spring 118 drives the rectangular block 116 to move via the slider 117, so that the rectangular block 116 drives the positioning pin 119 through the through hole 115 and then into the interior of the limiting hole 108. This makes it easier and faster to install and remove the bearing body 1.

[0051] Example 2, as Figure 1-4 As shown, the positioning assembly includes: a circular ring plate 103 movably mounted on one side of the annular plate 101, a plurality of connecting blocks 104 fixedly mounted on the outer surface of the circular ring plate 103, a groove 110 is provided on the outer surface of the connecting block 104, a circular hole 111 is provided inside the groove 110, and a bolt 112 is threaded inside the circular hole 111.

[0052] The bolt 112 is embedded inside the groove 110 to prevent it from protruding and affecting the rotation of the chain;

[0053] Multiple positioning holes 109 are provided on one outer surface of the annular plate 101;

[0054] Two locking blocks 105 are fixedly installed on one side of the annular plate 103, and the two locking blocks 105 are symmetrical to each other.

[0055] In this embodiment, the card block 105 is embedded inside the rectangular groove 113, which can position the rectangular block 116, so that it can drive the positioning pin 119 to be more stably embedded inside the limiting hole 108, so that the bearing body 1 is connected to the sprocket body 102.

[0056] Working principle: The positioning plate 106 is embedded in the slot 107. The positioning pin 119 is embedded in the limiting hole 108 under the elastic force of the spring 118, so that the positioning plate 106 is more stably embedded in the slot 107, thereby connecting the bearing body 1 and the sprocket body 102. A rectangular block 116 is installed on one side of the positioning pin 119. The rectangular block 116 can improve the stability of the positioning pin 119, so that it can better drive the positioning pin 119 through the through hole 115 and then embed into the limiting hole 108. Two sliders 117 fixedly installed on the outer surface of the rectangular block 116 can slide in the limiting groove 114. This not only improves the stability of the rectangular block 116, but also prevents the rectangular block 116 from falling out of the rectangular groove 113. When disassembling, pull the rectangular block 116 to drive the positioning pin 119 and move it out of the limiting hole 108. Disassembly is convenient and quick.

[0057] The locking block 105 is embedded into the rectangular groove 113 by the annular plate 103. The locking block 105 can position the rectangular block 116 and abut against the rectangular block 116 so that the positioning pin 119 is more stably embedded in the limiting hole 108, preventing the rectangular block 116 from sliding and improving the splicing effect of the bearing body 1 and the sprocket body 102. Then, the annular plate 103 is positioned by the bolt 112. The bolt 112 is threaded into the round hole 111 and then into the positioning hole 109, so that the annular plate 103 is connected to the ring plate 101. This not only limits the rectangular block 116, but also improves the stability of the positioning plate 106, so that it is better embedded in the groove 107.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
