Description

Technical Field

[0001] This utility model belongs to the field of synchronous belt pulley technology, and in particular relates to a quick-release buckle structure for synchronous belt pulleys. Background Technology

[0002] Synchronous pulleys are widely used mechanical transmission components. Together with synchronous belts, they form a synchronous pulley transmission system. The core of this system lies in the meshing transmission between the belt teeth and the pulley teeth, achieving precise control of the transmission ratio. Due to their precise, efficient, and stable transmission characteristics, synchronous pulleys are widely used in modern industrial machinery and equipment.

[0003] Traditional synchronous belt pulleys typically require a large axial space during installation, which hinders the compactness of the equipment structure and limits its miniaturization. Furthermore, the installation and maintenance of traditional synchronous belt pulleys often necessitate the disassembly of multiple pulleys and bearing housings on the drive shaft, resulting in cumbersome and time-consuming operations, increased downtime, and a significant impact on overall production efficiency.

Multiple connecting grooves are fixedly opened on its side. A connecting bolt is installed in each connecting groove. The connecting bolt moves through the wheel core halves and is threadedly connected to the other wheel core halves.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4 This utility model embodiment provides a quick-release buckle structure for a synchronous belt pulley, including:

[0023] The wheel core 1 includes two assembled wheel core halves 11. The middle of the wheel core halves 11 has a pre-reserved shaft groove 111 for connecting with an external drive shaft. Multiple connecting grooves 112 are fixedly opened on its side. Connecting bolts 12 are provided in the connecting grooves 112. The connecting bolts 12 movably pass through the wheel core halves 11 and are threadedly connected to the other wheel core halves 11.

[0024] The gear ring 2 includes multiple gear blocks 21 that are combined and mounted on the outside of the two wheel core halves 11;

[0025] The retaining ring 3 includes multiple assembled baffles 31, which are fixedly installed on both sides of the tooth block 21 by multiple fixing bolts 32.

[0026] In practical application, two wheel core halves 11 are connected by connecting bolt 12, and the wheel core 1 is fixedly installed on the external transmission shaft in conjunction with the reserved shaft groove 111. Then, multiple tooth blocks 21 are snapped on the outside of the wheel core halves 11 to form a toothed ring 2 that meshes with the synchronous belt. The baffle 31 is fixedly installed on both sides of the tooth blocks 21 by fixing bolt 32, so as to realize the quick installation of the synchronous belt pulley.

[0027] This embodiment reduces the axial installation space requirement of the synchronous belt pulley through its modular assembly and interlocking structure design. Its detachable and replaceable baffle 31 not only facilitates the installation of the synchronous belt, but can also be replaced according to the specifications of the synchronous belt, further improving flexibility and adaptability. It solves the problems of traditional synchronous belt pulleys in installation, debugging and maintenance. Based on the modular design of the synchronous belt pulley, it supports the partial replacement of worn parts, significantly reducing material costs.

[0028] Please see Figures 2 to 4 In a preferred embodiment of the present invention, the toothed block 21 is provided with positioning grooves 211 at both ends, and a plurality of positioning blocks 113 adapted to the positioning grooves 211 are fixedly provided on the outer side of the wheel core half 11 at the position corresponding to the positioning grooves 211. The positioning blocks 113 are movably engaged in the positioning grooves 211.

[0029] In practical applications, this embodiment uses the positioning block 113 to engage with the positioning groove 211 to achieve the installation and positioning of the tooth block 21, which facilitates the connection and installation of multiple tooth blocks 21.

[0030] Please see Figure 3 and Figure 4 In another preferred embodiment of this utility model, a spring 14 is movably installed inside the positioning block 113, and two locking blocks 13 are movably installed at both ends of the spring 14, with the two ends of the spring 14 respectively pressing and contacting the two locking blocks 13.

[0031] Furthermore, at both ends of the positioning groove 211, corresponding to the positions of the locking block 13, a locking groove 2111 is fixedly provided. The locking groove 2111 is configured as a through hole, and the locking block 13 is squeezed and locked in the locking groove 2111 by the spring 14.

[0032] In practical application, during the engagement of the positioning groove 211 and the positioning block 113, the block 13 is compressed inward by the toothed block 21, thereby compressing the spring 14 to store elastic potential energy. When the block 13 moves to align with the groove 2111, the spring 14 releases the stored elastic potential energy, pushing the block 13 into the groove 2111 and locking it in place. This automatically completes the connection between the toothed block 21 and the wheel core half 11, greatly simplifying the installation operation. Furthermore, by designing the groove 2111 as a through-hole structure, the block 13 can be squeezed from the outside to disengage from the groove 2111, thus separating the toothed block 21 from the wheel core half 11, facilitating the disassembly and maintenance of the toothed block 21.

[0033] Please see Figure 3 In another preferred embodiment of the present invention, a connecting groove 212 is fixedly provided on the tooth block 21, and a connecting bolt 22 is provided in the connecting groove 212. The connecting bolt 22 movably passes through the tooth block 21 and is threadedly connected to the side of the wheel core half 11.

[0034] In practical applications, the connecting bolt 22 in this embodiment uses a threaded connection to press and fix the tooth block 21 to the side of the wheel core half 11, which effectively avoids the problem of the tooth block 21 accidentally loosening from the wheel core half 11 when the transmission system is running at high speed or under vibration, thus ensuring the stability and safety of the transmission.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
