Description

Technical Field

[0001] The utility model relates to the technical field of transmission gears, in particular to an internal tooth chamfered transmission gear. Background Art

[0002] The meshing of the internal teeth and the gears is achieved by inserting a transmission shaft into the inner gear ring, so that the gear on the transmission shaft meshes with the reduction gear in the inner gear ring, thereby realizing transmission. For example, as shown in a gear seat for locking the internal gear of a rotating platform with Chinese patent application number CN202320162594.0, the two ends of the top of the base are symmetrically fixedly connected with mounting plug-in plates, the two ends of the bottom of the card seat are symmetrically provided with mounting plug-in slots, the left and right ends of the card seat are symmetrically provided with cavities, the two cavities are symmetrically fixedly connected with fixed plates at the ends close to each other, and the middle parts of the two fixed plates on the opposite sides are symmetrically connected with screw rods.

[0003] However, due to the interference fit between the inner ring gear and the gear transmission shaft, while achieving stable rotation, the inner ring gear and the gear transmission shaft are too tightly connected and are often hammered in by a hammer, making them difficult to disassemble. When the inner ring gear is damaged, the entire gear transmission component often needs to be replaced, which makes replacing the inner ring gear very inconvenient. Utility Model Content
