[0002] Spiral bevel gears are widely used in the fields of vehicles, engineering machinery, and mechanical products. The processing method has always been to use special machine tools with special disc cutters for gear milling. The adjustment of machine tools and cutters is complicated, and the versatility of the cutters is poor. Regrinding requires special grinders. The low processing efficiency of machine tools, especially the large wheels with basin angle teeth, has become a bottleneck restricting the production of spiral bevel gears

Embodiment Construction
[0019] Such as Figure 1 to Figure 3 As shown, the processing device adopted in the method of turning the helical forming of the corner gear of the spiral bevel gear basin of the present invention includes a lathe body 1 , a lathe main shaft 2 , an indexing device 3 and a lathe tool holder 4 . A lathe faceplate 8 is coaxially fixedly connected to the end surface of the lathe main shaft 2 , and the indexing device 3 is eccentrically and obliquely connected to the lathe faceplate 8 . The lathe tool holder 4 is provided with a three-sided edge forming turning tool 5 perpendicular to the end face of the lathe main shaft 2, and the turning tool 5 can move along the horizontal direction passing through the rotation center of the lathe main shaft 2 and the central axial direction of the lathe main shaft 2 respectively.
[0020] The lathe tool post 4 in this embodiment includes a first slider 401 and a second slider 402, the first slider 401 is slidably arranged on the first linear gu...

The invention relates to the field of arc-tooth bevel gear machining and discloses a spiral forming turning machining method for an arc-tooth bevel gear basin angle gear. The spiral forming turning machining method includes the following steps that firstly, an indexing device is eccentrically and obliquely fixed to a lathe spindle; then a basin angle gear blank is coaxially clamped on the indexingdevice, the inclination angle gamma between the indexing device and the end face of the lathe spindle is adjusted to be 180 degree-delta, wherein delta is the face cone angle of the basin angle gearblank; and finally, a three-face-blade forming turning tool is installed on a lathe tool rest, the three-face-blade forming turning tool is controlled to conduct feeding movement in the axial direction of the lathe spindle, and therefore the three-face-blade forming turning tool conducts relative spiral turning movement on the face cone of the basin angle gear blank. By means of the spiral formingturning machining method for the arc-tooth bevel gear basin angle gear, due to the fact that a common lathe is transformed, turning machining of the arc-tooth bevel gear basin angle gear is simply and effectively achieved, production and machining of the arc-tooth bevel gear do not depend on a special machine tool and a special disc-shaped tool, the production cost is reduced, the limitation of arc-tooth bevel gear basin angle gear machining in the current stage is avoided, and the application range of a common lathe is enlarged.
Description
technical field [0001] The invention relates to the field of spiral bevel gear processing, in particular to a method for spirally forming and turning the corner teeth of a spiral bevel gear basin. Background technique [0002] Spiral bevel gears are widely used in the fields of vehicles, engineering machinery, and mechanical products. The processing method has always been to use special machine tools with special disc cutters for gear milling. The adjustment of machine tools and cutters is complicated, and the versatility of the cutters is poor. Regrinding requires special grinders. The low processing efficiency of machine tools, especially the large wheels with basin angle teeth, has become a bottleneck restricting the production of spiral bevel gears. Lathe is the most versatile machine tool for machining. It is easy to operate, the tool price is low, the turning process is good, and it is easy to operate. It has a very wide range of applications in the field of machinery ...
