Abstract
The utility model discloses a mechanical bevel gear. The mechanical bevel gear comprises a gear body and oblique teeth, wherein an installation shaft hole is formed in the center of the gear body, a protruding ring is arranged inside the end portion of the installation shaft hole, a protruding ring base is arranged on the gear body which is close to one end of the protruding ring, crossed through holes are formed in the protruding ring base, a plurality of cavities with one closed ends and one open ends are formed uniformly in the gear body, cavity covers which are matched with the cavities are arranged on the cavities, and the oblique teeth are arranged on the periphery of the gear body. The mechanical bevel gear is simple in structure and reasonable in design, and the cavities with one closed ends and one open ends are filled with foam, so that noises caused by rotation of the gear can be effectively reduced; the crossed through holes are formed in the protruding ring base, so that the gear can be assembled and disassembled conveniently; the annular protruding ring is arranged inside the installation shaft hole, so that a bearing can be limited correctly, the bevel gear is not prone to abrasion, and the service life is prolonged.
Description
Technical field
The utility model relates to field of mechanical technique, relates in particular to a kind of mechanical helical gear.
Background technique
In the prior art, helical gear owing to spacing not accurate enough, and produces a large amount of noises in transmission process; Or the machining accuracy of profile of tooth is not enough, produces noise.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of mechanical helical gear.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mechanical helical gear, comprise gear mass and helical teeth, the gear mass center is provided with installation axle hole, be provided with bulge loop in the end of installation axle hole, gear mass near bulge loop one end is provided with the bulge loop base, offers the through hole of criss-crossing on the bulge loop base; Offer a plurality of ends on the gear mass equably and seal the cavity of an end opening, cavity is provided with the cavity lid with the cavity coupling.
As preferably, described cavity has 8.
As preferably, an end seals in the cavity of an end opening and is filled with foam.
Compared with prior art, advantage of the present utility model is: simple in structure, reasonable in design, an end seals in the cavity of an end opening and is filled with foam, can reduce the noise that gear rotates effectively; Offer the through hole of criss-crossing on the bulge loop base, gear can be easy for installation and removal; Be provided with bulge loop in the installation axle hole, can be spacing correct to bearing, helical gear is not easy wearing and tearing, increases the life-span.
