Abstract
The utility model discloses a gear which mainly comprises a circular gear main body; a shaft hole is formed in the center of the gear main body; a gear ring is arranged on the outer margin of the gear main body; and through holes are formed on the gear main body between the shaft hole and the gear ring. Preferably, the through holes are distributed in the shape of a circular ring that is concentric with the shaft hole, and the number of the through holes is nine preferably. The gear provided by the utility model has the advantages as follows: due to the adoption of the through holes, the gear main body between the shaft hole and the gear ring is free from the original solid structure, so that the material of single gear is greatly reduced, and the cost is effectively decreased; furthermore, the weight of the gear is also greatly reduced, so that the gear is more convenient to install and transport. Studies of the company show that the gear with the structure provided by the utility model can completely rival the conventional gear in the mechanical transmission property.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, especially a kind of gear.
Background technique
Gear is a mechanical part common during people live, by the transmission that is meshing with each other, existing gear mainly comprises circular gear body, be provided with axis hole at the gear body center, on the gabarit of gear body, be provided with gear ring, because the part between axis hole and gear ring is a solid construction, so the weight of gear is bigger, materials are also more, cost is higher, comparatively inconvenience, the especially gear of some big models in the transportation process are being installed, installation and transportation are required great effort especially, moreover, in forging process, also increased burden to forging equipment.
Summary of the invention
The purpose of this utility model is the gear that a kind of weight is little, cost is low that provides for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the gear that the utility model is designed, it mainly comprises circular gear body, is provided with axis hole at the gear body center, is provided with gear ring on the gabarit of gear body, is provided with through hole on the gear body between described axis hole and the gear ring.
As preferably, described through hole is the circular distribution concentric with axis hole.The quantity of described through hole is preferably 9.
The gear that the utility model obtains because the existence of through hole, makes that gear body between axis hole and the gear ring no longer is a solid construction in the past, the materials of single gear greatly reduce, and have reduced cost effectively, and, the weight of gear also greatly reduces, and is more convenient when installation and transportation.Repeatedly study through our company, adopt the gear of the utility model structure, on the mechanics transmission performance, can compare favourably with existing gear fully.
Description of drawings
Fig. 1 is embodiment 1 a structural representation;
Fig. 2 is embodiment 2 a structural representation;
Among the figure: gear body 1, gear ring 2, axis hole 3, through hole 4.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described gear of present embodiment, it mainly comprises circular gear body 1, is provided with axis hole 3 at gear body 1 center, on the gabarit of gear body 1, be provided with gear ring 2, on the gear body 1 between described axis hole 3 and the gear ring 2, be provided with 3 through holes 4.Described through hole 4 is the circular distribution concentric with axis hole 3.
The described gear of present embodiment because the existence of through hole 4, makes that gear body 1 between axis hole 3 and the gear ring 2 no longer is a solid construction in the past, the materials of single gear greatly reduce, and have reduced cost effectively, and, the weight of gear also greatly reduces, and is more convenient when installation and transportation.Repeatedly study through our company, adopt the gear of the utility model structure, on the mechanics transmission performance, can compare favourably with existing gear fully.
As shown in Figure 2, the described gear of present embodiment, it mainly comprises circular gear body 1, is provided with axis hole 3 at gear body 1 center, on the gabarit of gear body 1, be provided with gear ring 2, on the gear body 1 between described axis hole 3 and the gear ring 2, be provided with 9 through holes 4.Described through hole 4 is the circular distribution concentric with axis hole 3.
The described gear of present embodiment is compared with embodiment 1, can further save cost, alleviates gear weight.
Need to prove; the protection domain of this patent is not limited to the foregoing description; those of ordinary skill in the art enlightens according to above-mentioned technology; should do corresponding variation; as change the shape and the quantity of through hole 4; as long as realized goal of the invention of the present utility model, should all fall into the protection domain of this patent.
