What is the internal structure of the worm gear box?

  What is the internal structure of the worm gear box?Worm gear boxes are equipped in many large-scale equipment, which can be used to regulate the speed of the equipment. When using worm gear boxes, you need to follow the relevant methods of use, so that you can ensure that there will be no errors and regular maintenance.The worm gear box is composed of a worm and a worm wheel, and the relevant parameters must be calculated during production.Let us Zhejiang worm gear box manufacturer to introduce the internal structure.

Internal structure of worm gear box

(1) The meshing of the worm and worm wheel in the main section is the meshing of the involute rack and gear.

(2) In other sections of the parallel main section, there are a pair of different non-involute rack and pinion meshes, but regardless of the shape of the meshing tooth profile, there is a meshing point (touch point). The collection of these profiles shows that the meshing of the worm and worm gear is a line touch, and the meshing of each pair of gear teeth is also gradually engaged and gradually withdrawn, so the touch line also changes from short → long → short.As a result, the worm and worm gear drive is stable, has low vibration and noise, and carries a high level of skill.

(3)在主剖面内有基本参数：模数和压力角。关于蜗杆称轴面模数ma1和轴面压力角aa1；关于蜗轮称端面模数mt2和端面压力角at2。

(4) 蜗杆蜗轮传动能够获得较大传动比。因为蜗杆的齿数z1较少，蜗轮的齿数z2能够许多，因而传动比i12=w1/w2=z2/z1能够很大，通常i12=10 ~ 100。在分度组织或手动组织中，i12可达300以上。
