Abstract

The invention relates to a differential gear train of a double circular arc modified cycloid gear and belongs to the technical field of gear transmission designs and gears of mechanical equipment. The differential gear train comprises an inner gear ring, planet gears and a central gear, wherein the planet gears are mounted between the inner gear ring and the central gear; the meshing between the planet gears and the inner gear ring is internal contact and internal meshing; and the meshing between the planet gears and the central gear is external contact and internal meshing. According to the differential gear train, lateral clearance and top clearance are larger, so that the transmission is flexible; the tooth addendum and the tooth dedendum are smaller, so that clamping stagnation is not prone to occur; the tooth thickness of a gear root is wider, so that the bending strength of the gear root is larger; and the processing cost can be greatly reduced, the transmission efficiency is high, and the contact stress can be effectively reduced.

Description

technical field [0001] The invention relates to a double circular arc correction cycloidal gear differential gear train, which belongs to the field of mechanical equipment gear transmission design and gear technology. Background technique [0002] Gear failure accounts for more than 60% of various mechanical failures, so the research on gear meshing performance has long been an important research topic at home and abroad. The current research is mainly to effectively improve the performance, quality and life of the gears in the gear system used for mechanical transmission. Although the existing several commonly used gear structure types have their own uniqueness in improving the gear meshing and transmission performance, but Problems remain in reducing gear contact stresses during power transmission. [0003] The outstanding problems brought about by the unique meshing mode of involute gears are: as the gear speed increases or the load increases, the thermal deformation or ...
