Description

Technical Field

[0001] The utility model relates to the technical field of spiral bevel gear assembly, in particular to a spiral bevel gear which is easy to assemble. Background Art

[0002] The spiral bevel gear is a mechanical device used for transmission and speed change. It consists of a worm and a worm wheel, where the worm is a spiral-shaped shaft and the worm wheel has spiral-shaped teeth that mesh with the worm. The spiral bevel gear has many advantages, including high transmission efficiency, low noise level and smooth operation. These advantages make spiral bevel gears widely used in many industries, such as engineering machinery, electric power transmission, aerospace and other fields. The working principle of the spiral bevel gear is to transmit torque to the worm wheel through the rotational motion of the worm, thereby achieving a transmission effect. The spiral shape of the worm makes the contact point of the gear gradually move from the axial direction during the transmission process, thereby ensuring smooth transmission and reducing the impact and noise of the gear.

[0003] Firstly, due to the helical shape of the worm, it can provide a higher transmission ratio. This means that the spiral bevel gear can convert a higher speed rotation to a lower speed rotation while providing a larger torque output. Secondly, the spiral bevel gear has a good self-locking characteristic, that is, when the transmission stops, the worm can prevent the worm wheel from moving backward. This makes the spiral bevel gear very useful in applications that require position stability. In addition, the spiral bevel gear also has a lower noise level and higher transmission efficiency. Because the meshing of the worm and the worm wheel is helical, the spiral bevel gear produces less noise than other transmission devices and can provide higher transmission efficiency.

[0004] However, the existing spiral bevel gears cannot be lubricated during installation, resulting in friction and wear of the spiral bevel gears during installation. Therefore, a spiral bevel gear is proposed which has a more stable connection and can lubricate the spiral bevel gears during installation to reduce wear. Utility Model Content
