Abstract

The utility model discloses a small-size gear. The small size gear comprises a gear body, gear teeth are arranged on the gear body, and the inner circle of the gear body is provided with a bulge loop for fixing a gasket. According to the small-size gear provided by the utility model, improvements has made on the conventional gears, and the bulge loop for fixing the gasket is arranged on the inner circle of the gear body, such that the gasket can be prevented from sliding when the small-size gear is used for mounting a bearing and the gasket is used for limiting the outer circle of the bearing, thereby effectively raising installation accuracy of the small-size gear, reducing abrasion of the gear during usage, and prolonging service life.
