Instead of the common analytical model for involute gears machining, a general
mathematical model for two-parameter generating machining is developed in this study with …

The increasing demand for low noise and high strength leads to higher quality requirements
in manufacturing modified helical gears. Hobbing is the most widely employed cutting …

Sharpening helical hobs with a hob sharpener is relatively easy and efficient, but the hob
sharpener has poor versatility due to its tilted spindle for sharpening helical flutes. In this …

Plastic gears have many advantages over traditional metal gears, including a lower weight,
better design flexibility and an improved ability to absorb shock and vibration. Moreover …

Topological modification of gear surface is used to achieve better meshing transmission
performance and accuracy. However, in the traditional gear modification grinding process …

When calculating the grinding wheel curved shapes, the hob front angle of hob is usually
zero by default. In the actual production and processing, there are many hobs whose hob …
