Multifunctional gear

Abstract

The invention discloses a multifunctional gear. The gear comprises a circular gear body, a circle of outer teeth are arranged on the circumference of the outer end portion of the gear body, and the outer teeth and the gear body are of an integrated structure; the outer teeth are of a serrated structure, an inner hole is formed in the center of the gear body, two clamping grooves are symmetricallydistributed in the inner side of the inner hole, and a pair of arc protrusive blocks are arranged at the upper and lower sides of the gear body respectively, placed between the outer teeth and the inner hole and symmetrically distributed with the two clamping grooves as centers; a protective layer which is a sulfide layer is fixedly laid on the outer surfaces of the outer teeth, and the thicknessof the sulfide layer is 3-6 mm. By adopting the two clamping grooves distributed symmetrically to make the gravity center of the gear body overlapped with an axial center, during high-speed rotation,centrifugal force cannot be generated, so that abrasion between the clamping grooves and external connecting shafts is reduced, and the arc protrusive blocks can utilize the inertia during rotation, and therefore the working efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the field of electric tool auxiliary equipment, and in particular relates to a multifunctional gear. Background technique [0002] Gears are common mechanical parts in people's lives. Through mutual meshing and transmission, existing gears mainly include a circular gear body with a shaft hole at the center of the gear body and a ring gear on the outer profile of the gear body. The shape of ordinary gears is easy to wear, the service life is short, it cannot meet the needs of many aspects, and it is easy to rust, especially in the field of very high speed, the wear between the gear slot and the shaft will be very serious, resulting in a long life of the gear This is because the center of gravity of the gear deviates from the center of the shaft, and centrifugal force is generated during rotation, which accelerates the wear of the card slot. Contents of the invention [0003] The object of the present invention is to provide a...
