Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to an anti-deformation gear. Background Art

[0002] Gears are mainly used to transmit mechanical power, so as to achieve the purpose of favorable distribution of mechanical power. Gears refer to mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. Gears are prone to damage and deformation during operation. When a gear is damaged, it is time-consuming and laborious to replace it.

[0003] For example, a reinforced gear structure with publication number CN215861613U includes a gear and a rotating shaft, and one end of the gear and the rotating shaft set is provided with a step fixedly connected to the gear, and the outer diameter of the step is equal to the outer diameter of the gear. The beneficial effects of the utility model are as follows: a step is added to the assembly end of the gear and the rotating shaft, the outer diameter of the step is equal to the diameter of the tooth top circle, and is connected to the tooth. The step has a chamfer, which is convenient for the gear processing and demoulding, and reduces the influence of the right-angle hard force of the step on the press-fit gear, so that the bottom strength of the gear is enhanced. When a large torque working condition is required, the interference between the rotating shaft and the gear is increased to achieve a large torque, while ensuring that the gear does not crack during the actual pressing process, and ensuring the stability of the gear.

[0004] The above patent proposes that the existing gears usually reduce the influence of the step right-angle hardness on the press-fitted gears, so that the bottom strength of the gears can be enhanced, but it is not convenient to strengthen the gears for a second time to prevent damage and deformation, which leads to a reduction in the service life of the gears, and it is not convenient to adjust the fixture spacing. Therefore, the utility model provides a gear that is anti-deformation. Summary of the invention
