Gear skiving offers great opportunities
for production with step-changing
productivity, particularly for internal gears,
whilst offering high-quality finishing
capabilities and being applicable on a
5-axis machine tool with its inherent
flexibility and multifunctionality.
Mitsubishi Heavy Industries, Ltd. (MHI) conducted a comparison test between the super skiving cutter and the pinion skiving cutter used in the conventional skiving process and the test results are reported here.
Automotive gear manufacturers have implemented significant improvements in external planetary gear manufacturing yielding quieter gears. In addition, process stability has increased due to the post-heat treatment finishing processes employed. This article explains various complete solutions for cutting and finishing internal ring gears.
Call it new wine in old bottles, or old wine in new bottles, but
gear skiving has certainly aged well over time. Gear skiving's evolution, perhaps gaining momentum most dramatically since around 2004, has ultimately led to rather dramatic technological advancement and cost saving in the manufacture of certain gears.
The DVS gearing specialist Praewema Antriebstechnik continues to expand its technological expertise in order to keep pace with the growing significance of planetary geartrains for automatic and particularly electric vehicles, with the associated need for even higher-precision production of toothed gear components.
