DIFFERENTIAL TRANSMISSION Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: this differential transmission is intended for levelling load between pinion gears. Stopping of external central gear is effected by means of equalizing link which is pivotally connected through rods with external central gear and transmission housing. Vertical rods having their axes parallel to each other are used to connect equalizing link with transmission housing. Horizontal rods having their axes parallel to each other are used to connect equalizing link with external central gear. Connection of rods with equalizing link is effected through spherical joints. Connection of rods with transmission housing and external central gear is effected through cylindrical joints. Installed in lower horizontal rod is cylindrical coil spring which by its one end interacts with external central gear, and by its other end it interacts with transmission housing through intermediate sleeve. Aforesaid embodiment of differential transmission improves its general arrangement and enhances load bearing capacity. EFFECT: higher efficiency. 4 dwg
