[0002] Bevel gears are an important component in the field of mechanical transmission, widely used in various industrial equipment and mechanical devices. Their performance and quality directly affect the efficiency, stability, and reliability of the entire transmission system. With the continuous development of industrial technology, higher requirements have been placed on the performance, manufacturing process, installation, commissioning, and maintenance of bevel gears. One-piece bevel gears are usually manufactured as a whole, with the teeth and hub being produced by methods such as forging, casting, or machining.
[0003] In response, Chinese patent application number CN202121794687.2 discloses a bevel gear, belonging to the field of gear manufacturing technology. It solves the problem of high operating noise in existing bevel gears. This bevel gear includes a first end face and a second end face. Multiple equidistantly distributed first teeth are fixedly arranged along the outer edge of the first end face, and multiple equidistantly distributed second teeth are fixedly arranged along the outer edge of the second end face. The second teeth mesh with the first teeth. A drive shaft sleeve is inserted through the middle of the first end face, and a driven shaft sleeve is inserted through the middle of the second end face. A drive shaft connection channel is opened in the middle of the drive shaft sleeve, and four annularly distributed square grooves are opened inside the drive shaft connection channel.
[0004] However, existing bevel gears require complete disassembly and replacement when the gear parts are worn or damaged, which can easily lead to waste and increase maintenance costs. Furthermore, replacing the entire gear also requires adjustment and break-in, which affects assembly and usage efficiency.
[0005] Therefore, in order to solve the above problems, a bevel gear with modular assembly is proposed. Summary of the Invention
[0006] The purpose of this utility model is to provide a modular assembly bevel gear to solve the problems mentioned in the background art, which are that existing bevel gears require complete disassembly and replacement when the gear parts are worn or damaged, which easily leads to waste, increases maintenance costs, and requires adjustment and break-in when replacing the entire gear, affecting assembly and usage efficiency.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a combined bevel gear, comprising an assembly disc, wherein an assembly tooth is inserted and assembled on the upper part of the assembly disc, and the assembly disc and the assembly tooth are assembled by a tooth fixing screw; a mounting base is supported and assembled at the bottom of the assembly disc, and the assembly disc and the mounting base are assembled by a limiting pin; and an inner shaft slot is provided in the middle of the mounting base.
[0008] This method facilitates the assembly of corresponding bevel gears. This modular structure makes transportation and installation convenient, and in the event of damage, only the damaged section needs to be replaced, rather than the entire shaft, thus reducing maintenance costs.

[0015] As a further step of this solution, an outer sleeve is integrally provided on the lower outer side of the assembly plate, and a corresponding inner support cylinder is provided on the lower inner side of the assembly plate. The inner extension cylinder is inserted and assembled inside the inner support cylinder, and the space between the outer sleeve and the inner support cylinder matches the protrusion of the circumferential boss.
[0016] This method facilitates the fitting and assembly of the lower part of the assembly plate and the upper part of the mounting chassis, making it easier to form a stable whole in subsequent assembly, and making it more stable and convenient to use.
[0017] As a further step of this solution, the top view of the inner extension cylinder is hexagonal, and the inner support cylinder has an inner slot corresponding to the outer wall of the inner extension cylinder.
[0018] This method facilitates the interlocking of the chassis and assembly plate, making subsequent drive installation easier and more stable after assembly, thus making it more convenient to use.
[0019] As a further step of this solution, an extension shaft cylinder is integrally extended from the center of the bottom of the mounting chassis, and an inner shaft slot is opened through the center of it. A shaft keyway is opened on one side of the inner wall of the inner shaft slot, and a bottom pin through hole is opened on the outer wall of the extension shaft cylinder.
[0020] This method facilitates the stable assembly of the drive shaft, making it more convenient to use.
[0021] As a further step of this solution, the limiting pins are sequentially inserted and connected to the outer sleeve, the circumferential boss, the inner support cylinder and the inner extension cylinder from the outside to the inside. The three sets of limiting pins are arranged in a triangular assembly and dispersed around the perimeter. The outer sleeve, the circumferential boss, the inner support cylinder and the inner extension cylinder are all provided with horizontal threaded grooves corresponding to the limiting pins. The outer wall of the outer sleeve is provided with a side recessed groove corresponding to the outer cap of the limiting pin.
[0022] This method allows the assembly plate and mounting chassis to form a relatively stable whole after being assembled using limit pins, making subsequent transmission, installation, and use more convenient.
[0023] Compared with the prior art, the advantages of this utility model are: this utility model is easy to assemble and use according to the needs of use, and it is also easy to disassemble, replace and maintain parts, making it convenient to transport and install. Moreover, when damage occurs, only the damaged section needs to be replaced, instead of replacing the entire shaft, which reduces maintenance costs.
[0024] This utility model features assembly teeth that, supported by an assembly plate, are assembled and secured with screws. This facilitates disassembly and assembly of the entire assembly, making it more convenient to use. It also allows for easy disassembly and replacement of individual assembly teeth in case of damage, avoiding the waste of replacing the entire component due to partial damage and saving costs. Furthermore, it facilitates individual processing and subsequent assembly during production, as well as convenient transportation, making operation and use more convenient. This design improves the convenience and practicality of modular bevel gear assembly.
[0025] This utility model, by providing a mounting base and an inner shaft slot, facilitates the support and assembly of the gear teeth and mounting plate, and also facilitates assembly onto the drive shaft as needed, making operation and use more convenient and facilitating subsequent disassembly and replacement. Furthermore, the inner extension cylinder and circumferential boss, along with the outer sleeve, inner support cylinder, and inner slot, facilitate relative limiting and locking assembly, making it easier to form a relatively stable integral bevel gear after assembly, thus making use more convenient. This design improves the convenience and practicality of the modular assembly bevel gear. Attached Figure Description
