新型多功能扳手设计

通过对普通扳手使用特点的分析,指出了其存在的诸多不足之处。提出了既能快速,也能增力拆、装螺栓或螺母;既适用于常态,也适用于需较大力矩的状态;且手柄能连续回转的多功能扳手的设计思路。论述了多功能扳手主要设计参数齿轮齿数、模数和传动轴轴径的计算方法,阐述了其主要结构形式和零部件的组成。新型多功能扳手在实际生产中的使用结果表明,完全达到了高效、省力和拓展使用范围的目的。

Design of New Type of Multifunctional Wrench

Through the analysis to the characteristics of ordinary wrench,pointing out the deficiencies of the existing.Put forward to the design idea of multifunctional wrench which not only can quickly,also can be removed,install the bolt or nut;not only be applicable to normal,also applies to the required torque state and the handle can continuous rotary.Elaborate the main design parameters of multifunctional wrench gear number of teeth,modulus,drive shaft diameter calculation method and the main structure and components.Multifunctional wrench is used in the actual production results show that fully meet the high efficiency,labor saving,and expand the scope of use of the objective.
