Among its figure: the 1-motor; The 2-slide block; The 3-screw mandrel; The 4-shift fork; The driven connecting lever of 5-; The 6-output shaft; The 7-spring; 8-driven force gear; The 9-rivet; The 10-core bar that leads; The 11-power gear; 12-DIP bolt.
Embodiment
The utility model illustrates specific implementation method with structural representation shown in Figure 1 as most preferred embodiment:
At first, according to designing requirement coupling reduction gearing, with screw mandrel 3 modules of slide block 2, the model of drive motors 1, the modulus of elasticity of spring 7 is established the relative fixed position of motor 1, screw mandrel 2, output shaft 6.
For the forging of shift fork 4 classes and the product component after the machine work, should set certain material timeliness, lost efficacy to eliminate the metal fatigue that brings owing to stress, thus the stability in use of guarantee integral product.
For spring 7 and guiding core bar 10, shift fork 4 and output shaft 6; Should consider the cooperation that it is axial, avoid the generation of the screens phenomenon that causes because of off-centre.
The above only is a preferred embodiment of the present utility model; can not limit protection range of the present utility model with it; the utility model also can have other structural change; so long as the equalization of doing according to protection range of the present utility model changes and modify, all should belong in the scope that the utility model contains.
