The invention relates to the technical field of bevel gear manufacturing, and particularly discloses a spherical involute demonstration teaching tool. The spherical involute demonstration teaching tool comprises a disc, a bevel gear combination, a rotating shaft, a cone cover, an indicating lamp and a driving device. The disc is connected with the cone cover through the bevel gear combination andthe rotating shaft; the cone cover is in a round table shape; one end of the rotating shaft is inserted in the cone cover in the axis direction of the cone cover and can freely rotate relative to thecone cover; the other end of the rotating shaft is bent, is connected with the circle center of the bottom face of the disc, and can freely rotate relative to the disc; the circle center of the bottomface of the disc coincides with the vertex of the cone cover, and the bottom face of the disc and the side face of the cone cover are tangent; the bevel gear combination comprises a first bevel gearand a second bevel gear which are mutually engaged; the rotating shaft penetrates through the first bevel gear and the second bevel gear; the first bevel gear is fixedly connected with the bottom faceof the disc, and the second bevel gear is fixedly connected with the top of the cone cover; the indicating lamp is arranged at the edge of the disc; and the driving device is arranged in the cone cover. The spherical involute can be intuitively embodied through the spherical involute demonstration teaching tool.
Description
Technical field [0001] The invention relates to the technical field of bevel gear manufacturing, in particular to a spherical involute demonstration teaching aid. Background technique [0002] Bevel gears are one of the common originals in mechanical manufacturing engineering. The bevel gear drawing method is the key to drawing graphics. The conventional drawing method is slow and the steps are complicated. The circular positioning method is adopted, and the spherical involute meshing principle is applied to the straight tooth bevel gear drawing method to make the drawing graphics concise, accurate, practical, Fast. Gear is the most widely used transmission part in mechanical transmission. Gear transmission is the most important part of the transmission of motion and power in modern machines. It plays an important role in the rotation between the intersecting two shafts. [0003] When the involute gear meshes, due to the characteristics of the involute, the gears will always keep...
