The invention relates to a combined planetary gear drive mechanism applicable to a hot die forging press. The combined planetary gear drive mechanism comprises servo motors, an output shaft of each servo motor is connected with a large belt wheel through a small belt wheel and a driving belt, each large belt wheel is mounted on a large flange through a sliding bearing, the outer side of each large belt wheel is connected with a brake which is a belt brake and connected with a gear shaft through an involute spline, one end of each gear shaft is a sun gear in planetary gear drive, the sun gears form planetary gear drive together with planetary gears, inner gear rings and planetary carriers, each gear shaft is an input end, each planetary carrier is an output end, each inner gear ring is fixed on the corresponding large flange, each planetary gear is connected with each planetary carrier which is connected with a crank, and the cranks are connected with a connecting rod of the hot die forging press. The combined planetary gear drive mechanism has the advantages of small size, compact structure, high transmission power and high bearing capacity, the planetary gear drive is stable, impact resistance and vibration resistance are high, power dividing can be achieved effectively, and accordingly needed power of the servo motors is lowered, and cost is saved.
Description
technical field [0001] The invention belongs to the technical field of manufacturing hot die forging presses, and in particular relates to a combined planetary gear transmission mechanism suitable for hot die forging presses. Background technique [0002] Hot die forging press is a forging equipment that realizes hot forming of metal blanks by means of dies. On the hot die forging press, various hot die forging processes such as open die forging, closed die forging and extrusion can be completed. Hot die forging with multiple cavities can be carried out by manual operation or automatic transfer device. Hot die forging press is an indispensable manufacturing equipment in the fields of machinery manufacturing, military industry, aerospace and other fields. The transmission mechanism of traditional hot die forging presses mostly adopts one-stage or multi-stage ordinary involute gear transmission. This kind of gear transmission has a small load-carrying capacity, which will le...
