Abstract
The utility model relates to a gear with low cost, belongs to the gear structural improvement technical field. The utility model is completely made of plastic and comprises a peripheric disc, the center of which is provided with a shaft hole. A first cylindrical part is formed by extending the shaft hole to the both ends, and a second cylindrical part is formed through extending an interspace between the first cylindrical part and the fluted disc outer ring. A plurality of radial first stiffeners are arranged between the second cylindrical part and the first cylindrical part, and a plurality of radial second stiffeners are positioned between the fluted disc outer ring and the second cylindrical part. By using the utility model mode, which has lighter weight and lower manufacturing cost, the great plastic consumption, high manufacturing cost and the other problems in the prior art are solved.
Description
Technical field
The utility model relates to a kind of low-cost gear, belongs to the improved technical field of gear structure.
Technical background
Be weight reduction and noise, the normal plastic gear that adopts replaces metal gear in driving mechanism.Yet in the prior art, plastic gear mostly is full solid construction, and the plastics amount of expending of making gear is bigger, and its manufacture cost is higher.
Summary of the invention
The utility model purpose is to provide a kind of weight lighter, the low-cost gear that manufacture cost is lower, and the plastics amount of expending that has solved the prior art existence is bigger, and its manufacture cost is than problems such as height.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: its integral body is made of plastics, comprise peripheral disk body, the center is provided with axis hole, described axis hole extends to form first cylindrical portion to two ends, extend to form second cylindrical portion to two ends between described first cylindrical portion and the fluted disc outer ring, be provided with some first stiffening ribs radially between described second cylindrical portion and first cylindrical portion, be provided with some second stiffening ribs radially between the described fluted disc outer ring and second cylindrical portion.Form cavity between first cylindrical portion of the present utility model and second cylindrical portion, play the effect of reinforcing first cylindrical portion and second cylindrical portion between first cylindrical portion and second cylindrical portion and adopt first stiffening rib to be connected, guaranteeing under the prerequisite that the strength of gear teeth requires, further alleviated the weight of gear on the one hand, saved on the other hand and made the spent plastics of gear, reduced manufacture cost.
As preferably, the number of described first stiffening rib is the 4-8 root.Wherein first stiffening rib evenly distributes along circumference between first cylindrical portion and second cylindrical portion.
As preferably, the number of described second stiffening rib is the 6-10 root.Wherein second stiffening rib evenly distributes along circumference between second cylindrical portion and fluted disc.
As preferably, the wall thickness of described first cylindrical portion be the second cylindrical portion wall thickness 1.5-2.5 doubly.Wherein, first cylindrical portion is adopted thicker structure, can guarantee the reliability that gear center hole and axle assemble.
Therefore, it is lighter to the utlity model has weight, characteristics such as manufacture cost is lower.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
