Abstract
Disclosed is a gear milling head, wherein a main shaft and a motor transmit power through gears, a gear on a motor power output shaft can transmit power to a gear on a main shaft assembly through a speed gear group for driving the main shaft to rotate, and the high-gear and the low-gear rotary speed conversion of the main shaft is realized through pushing a shift gear in the speed gear group by a shift oil cylinder. Through adopting the gear transmission, the constant drive gear ratio can be guaranteed, the transmission motion is accurate and reliable, and the drive efficiency is over 98%, and the gear transmission can obtain higher drive efficiency, and can greatly improve the production efficiency after being applied in common mechanical element machining. The gear milling head has compact structure as all components are installed in a main shaft box, can be widely applied, can be used for machining planes and holes of black metal or non-ferrous metal elements, and can be installed on various vehicle digital control milling machines and vertical machining center machine tools as a modular cutting function component.
