Title:
GEAR PAIR, ANTI-TOOTH-SKIPPING MECHANISM OF GEAR, AND ELECTRIC SCISSOR OR PLIER TYPE TOOL
Document Type and Number:
WIPO Patent Application WO/2023/138500
Kind Code:
A1
Abstract:
A gear pair, comprising a driving gear (4) and a driven side swing gear (5) which mesh with each other, wherein anti-tooth-skipping structures are provided on the driving gear and the driven side swing gear, and the anti-tooth-skipping structure is a tooth surface (57) with an angle of 75-90 degrees; on the driven side swing gear, the tooth surface is a shearing stress working face when the driven side swing gear swings and meshes; and an included angle between the shearing stress working face and a horizontal plane is 0-15 degrees. The present invention further relates to an anti-tooth-skipping mechanism of a gear, an electric scissor or plier type tool and a bevel gear pair. The anti-tooth-skipping mechanism of a gear reduces an outward deflection normal force of the driven side swing gear, so that the driven side swing gear is less prone to slipping and tooth skipping, a shearing force on the driven side swing gear always faces a meshing direction thereof with the driving gear, that is, a force in the shearing force that is opposite the direction in which the driven side swing gear meshes with the driving gear is effectively reduced, and the force that disengages from meshing is effectively lowered, thereby decreasing the risk of gear slipping, and solving the problem of tooth skipping of the driven side swing gear.
