Asymmetric tooth profile design method based on multistage worm gear transmission structure
The invention discloses an asymmetric tooth profile design method based on a multi-stage worm gear transmission structure, and the method comprises the steps: calculating a limit torque borne by each stage of transmission structure at a limit low temperature according to an original multi-stage worm gear transmission structure during the design of the transmission structure, and comparing the limit torque with a preset safety value, according to the method, the worm gear transmission structure which is prone to damage at the limit low temperature can be recognized, namely, the to-be-corrected structure needing to be adjusted is recognized, the influence of the limit low temperature on the limit load is considered, and it is guaranteed that the scheme meets the load requirement. And then, performing parameter adjustment on a pressurizing surface of a worm in the to-be-corrected structure, specifically, performing parameter adjustment on a first pressure angle of the pressurizing surface according to the preloading temperature and the limit load, so that the first pressure angle is greater than a second pressure angle of a non-pressurizing surface, and the bearing capacity of the corresponding to-be-corrected structure is increased. Therefore, the hidden automobile door handle can work normally without occupying extra space under the conditions of low temperature and high load.
本发明公开了一种基于多级蜗杆齿轮传动结构的非对称齿廓设计方法，进行传动结构的设计时，先根据原有的多级蜗杆齿轮传动结构计算各级传动结构在极限低温下受到的极限扭矩，通过极限扭矩与预设安全值进行比较，能够识别在极限低温中容易出现损坏的蜗杆齿轮传动结构，即识别需要调整的待校正结构，其考虑了极限低温对极限负载的影响，以保证本方案满足负载要求。接着，对待校正结构中的蜗杆的加压面进行校调参，具体为根据预载温度及极限负载，对加压面的第一压力角进行调参，使第一压力角大于非加压面的第二压力角，使得对应的待校正结构承载能力得到增加，进而使得隐藏式汽车门把手在低温且高负载的情况下，不需要额外占用空间也能够正常工作。
