Description

Technical Field

[0001] This invention relates to a bevel gear assembly with a center hole and bushing to improve service life, which can be widely used in differential transmission systems.

[0002] As a key component of the transmission system, the reliability of bevel gears directly affects the transmission capacity. Existing bevel gears, because they have no bushing in the center hole and are in direct contact with the mating gear shaft, are prone to wear, corrosion, and galling in high-speed, high-temperature, and harsh environments, resulting in a short service life for both the bevel gear and the mating gear shaft. Summary of the Invention

[0003] The purpose of this invention is to provide a bevel gear assembly with a central hole bushing that improves service life by achieving reliable bushing positioning, secure fixing, reliable transmission, long service life of the bevel gear and mating gear shaft, low maintenance cost, convenient maintenance, and wear protection and buffering.

[0004] To achieve the above objectives, the present invention provides a bevel gear assembly with a central hole and bushing to improve service life. The assembly includes a bevel gear having a central hole, a bushing shoulder hole at one end of the central hole, and a bushing step stop hole at the other end of the central hole. A bushing with a shoulder is installed in the central hole of the bevel gear via an interference fit. The bushing is fitted into the central hole of the bevel gear, the bushing shoulder mates with the bushing shoulder hole of the bevel gear, and the end of the bushing is pressed into the end face of the bushing step stop hole of the bevel gear, ensuring that the bushing is positioned inside the central hole of the bevel gear.

[0005] The present invention relates to a bevel gear assembly with a center hole and bushing to improve service life. The outer diameter of the bushing is larger than the size of the center hole of the bevel gear, and the outer diameter of the bushing and the center hole of the bevel gear are interference fit to prevent the bushing from rotating inside the center hole of the bevel gear.

[0006] The present invention relates to a bevel gear assembly with a central hole and bushing to improve service life. The bushing has a tapered shoulder structure, which matches and fits tightly with the tapered bushing shoulder hole of the bevel gear.

[0007] The present invention relates to a bevel gear assembly with a central hole and bushing to improve service life, wherein the bushing is made of high-strength aluminum bronze alloy.

[0008] The present invention relates to a bevel gear assembly with a central hole bushing to improve service life, wherein the high-strength aluminum bronze alloy material is ZCuZn25Al16Fe3Mn3.

[0009] This invention relates to a bevel gear assembly with a center hole and bushing to improve service life. The bevel gear has a bushing shoulder hole and a bushing step stop hole to prevent axial movement of the bushing. The bevel gear and bushing are interference-fitted to prevent the bushing from rotating inside the center hole of the bevel gear. This achieves reliable bushing positioning and secure fixing.

[0010] This invention relates to a bevel gear assembly with a center hole bushing to improve service life. The bushing is made of high-strength aluminum bronze alloy ZCuZn25Al16Fe3Mn3, which possesses excellent wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, and thermal fatigue resistance, allowing it to operate continuously at temperatures below 400℃. When this type of bushing mates with the mating gear shaft, it prevents wear and corrosion damage to the bevel gear's center hole and the mating gear shaft even under high-speed, high-temperature, and harsh environments, thus extending the service life of both the bevel gear and the mating gear shaft.

[0011] This invention relates to a bevel gear assembly with a center hole and bushing to improve service life. The bevel gear features a bushing shoulder hole and a bushing stepped stop hole. The bushing is embedded within the bushing shoulder hole, center hole, and bushing stepped stop hole of the bevel gear, ensuring reliable axial positioning. Simultaneously, the bevel gear and bushing are connected by an interference fit to prevent rotation. Therefore, the connection between the two is firm and reliable, effectively preventing the bushing from moving or rotating within the center hole of the bevel gear, thus avoiding interference with the normal operation of the bevel gear and ensuring reliable transmission when working with the mating gear shaft.

[0012] This invention relates to a bevel gear assembly with a central hole and bushing to improve service life. Because it employs a wear-resistant, high-temperature-resistant, and corrosion-resistant bushing structure, the gear shaft it mates with will not experience wear, corrosion, or galling. Therefore, it has a long service life.

[0013] The bevel gear assembly of the present invention, which improves service life by adding a bushing to the center hole, adopts a high-strength aluminum bronze alloy bushing structure. Under impact load, it absorbs vibration through elastic deformation, avoiding the initiation of cracks caused by stress concentration. Therefore, it plays a role in wear protection and buffering.

[0014] This invention relates to a bevel gear assembly with a center hole bushing to improve service life. Even in the event of minor wear, because the high-strength aluminum bronze alloy bushing is less hard than the mating gear shaft, only the bushing will be damaged, while the mating gear shaft will remain unaffected. The bevel gear tooth surface will also remain unaffected; only the bushing needs to be replaced. Therefore, maintenance costs are low.

[0015] The bevel gear assembly of the present invention, which improves service life by adding a bushing to the center hole, adopts a modular bushing design, which simplifies the maintenance process and reduces replacement costs, thus making maintenance convenient.

[0016] In summary, the bevel gear assembly of the present invention, which improves service life by adding a bushing to the center hole, achieves reliable bushing positioning, secure fixing, reliable transmission, long service life of the bevel gear and mating gear shaft, low maintenance cost, convenient maintenance, and plays a role in wear protection and buffering.
