Abstract
The utility model relates to an injection moulding gear. The injection moulding gear mainly comprises an injection moulding body and a shaft, wherein the shaft is arranged in the internal center of the injection moulding body; the tooth surface at the periphery of the injection moulding body adopts the structure of a helical tooth surface formed through direct injection moulding; and the helical tooth surface structure adopts high-precision gear hobbing formation. By forming the helical tooth surface through direct injection moulding, the utility model has the beneficial effects that the precision of the gear is greatly improved; the qualification rate of products is improved; the production cost is further saved; the production is more convenient and faster; and the performance also can be more stable.
Description
Technical field
The utility model relates generally to the gear structure field, mainly is a kind of injection made gear.
Background technique
In recent years, domestic and international many producers come the alternative metals gear with injection made gear, have therefrom obtained good economic benefit.Compare with metal gear, injection made gear mainly contains three advantages: one, injection made gear has alleviated weight greatly; Two, reduce the Gear Production cost, and improved manufacturing efficiency; Three, reduced noise.So the application of injection made gear on reducing motor in the market is more extensive.Yet because the tooth profile error of injection made gear is big, precision is not high, uses and is subjected to very big influence.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, a kind of highi degree of accuracy is provided, more saves the injection made gear of cost.
The utility model solves the technological scheme that its technical problem adopts: this injection made gear, mainly comprise injection molding body and axle, and the inside center of injection molding body is provided with axle, and the flank of tooth that injection molding body is placed outward is the pitch face structure of direct molding and forming.
The pitch face structure of the described flank of tooth adopts highi degree of accuracy gear hobbing moulding.
The effect that the utility model is useful is: the utility model adopts direct molding and forming, and forms the characteristics of pitch face, has improved the precision of gear greatly, improved the up-to-standard rate of product, further saved cost of production, produced more conveniently, performance is also more stable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: injection molding body 1, axle 2, the flank of tooth 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, this injection made gear, mainly comprise injection molding body 1 and axle 2, the inside center of injection molding body 1 is provided with axle 2, the injection molding body 1 outer flank of tooth of placing 3 is the pitch face structure of direct molding and forming, and directly the characteristics of molding and forming have improved the precision of the flank of tooth and the yield rate of gear, and the pitch face structure of the flank of tooth 3 of institute's moulding adopts smart roll method gear hobbing by high precision gear hobber again, the flank of tooth 3 precision of gear have further been improved again, to reach more stable product performance.
In addition to the implementation, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
