Differential assembly planetary gear with reinforcing skirt

The invention discloses a differential assembly planetary gear with a reinforcing skirt. The differential assembly planetary gear comprises an inner hole, a spherical surface and a plurality of involute bevel gears. The differential assembly planetary gear is characterized in that a reinforcing skirt structure is arranged between every two adjacent involute bevel gears. The reinforcing skit is used for connecting the involute bevel gears of the planetary gear, and the design of the reinforcing skirt structure is realized through height H, a diameter phi D and a circular-arc R; and while the structure design requirements of the reinforcing skirt guarantee that the planetary gear is in motion connection to a half-axle gear, the reinforcing skirt does not generate motion interference. The planetary gear is designed with the skirt structure, so that strength is remarkably improved; according to planetary gear spherical surface and inner hole surface design rolling requirements, processingis not performed after th
