Because the gear shaper cutter can process both spur gears and helical gears (provided that the modulus and pressure angle are the same), and the movement of the gear shaper cutter (cutter tooth) is along the normal direction of helical gears, the normal parameters of helical gears (including modulus and pressure angle, etc.). ) is the standard value.

Gear-the core component of high-speed rail
CRRC Qishuyan Locomotive & Rolling Stock Technology Research Institute Co., Ltd. (hereinafter referred to as "CRRC Qishuyan Institute") is an R&D institution specializing in basic materials, basic technologies and basic parts of rail transit equipment in China, and an R&D and industrialization unit of key core parts of rail transit in China.
As a national technological innovation demonstration enterprise, a national high-tech enterprise and an innovative enterprise in Jiangsu Province, CRRC Qishuyan has built a national enterprise technology center, a national postdoctoral research center, a national accredited laboratory, four provincial engineering centers and two academician workstations. Won the National Science and Technology Progress Award 12 (3 first prizes) and more than 20 provincial and ministerial awards 120.
As one of the undertakers of the technical research and product development of key core components in the sixth speed increase of China Railway, CRRC Qishuyan Institute has made outstanding contributions to the speed increase of China Railway, running at an ultra-high speed of 840 kilometers per hour, and pushing China Rail Transit Station to the top of the world.
People's Network-"Gear" turns China high-speed rail.
