Abstract
The utility model belongs to the technical field of gears, and relates to a driven three-speed gear, which solves the technical problems that an existing three-speed gear is unreasonable in design and the like. The driven three-speed gear comprises a disk-shaped gear body, wherein a plurality of teeth are arranged on the edge of the gear body; a shaft hole penetrating through the gear body axially is formed in the center of the gear body; a positioning structure is arranged on the wall of the shaft hole; and the teeth are oblique teeth whose number is 41. The driven three-speed gear has the advantages that the design is reasonable, the service life can be prolonged, the meshing property is good, the structure is firm, the gear can also be detached, and the like.
Description
Technical field
The utility model belongs to the gear technique field, relates in particular to a kind of driven three gear teeth.
Background technique
Gear is can the intermeshing mechanical parts that tooth is arranged.There is tooth to mesh continuously on its wheel rim and transmits motion and power.Generally comprise gear body, the gear teeth and teeth groove.To drive by linking mechanism in the time of its speed change gear shift, mostly existing driven three gear teeth are the through ship tooth, and mostly the gear body generally is to adopt welding manner to carry out firm fixing with being connected of linking mechanism, it structurally can satisfy usage requirement, and structural strength is also higher; But, at first, the through ship tooth bearing capacity low, stationarity during transmission is poor, engagement property is poor, and secondly, directly welding makes the relative permanent set of structure, when needing repairing dismounting, suitable large of difficulty, and, the component around also easily destroying during dismounting, user cost is increased, directly cause product various quality problems to occur.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, can improve working life, and engagement property is good, the driven three gear teeth that structure is firm but also removable.
For achieving the above object, the utility model has adopted following technical proposal: a kind of driven three gear teeth, comprise gear mass in the form of annular discs, be provided with some teeth at the gear mass edge, be provided with at the gear mass center axis hole that axially runs through described gear mass, it is characterized in that, described axis hole hole wall is provided with position structure, and described teeth are that helical teeth and quantity are 41.The engagement of helical teeth tooth is good, the stability in the time of can improving transmission, and in addition, position structure can be easy for installation and removal, and the quality of product is relatively high.
In above-mentioned driven three gear teeth, described position structure comprises involute splines.Be easy for installation and removal, it is firm to locate.
In above-mentioned driven three gear teeth, the described involute splines number of teeth is 28.
In above-mentioned driven three gear teeth, described gear mass is respectively equipped with first ring connected in star and the second annular groove on bi-side, and the groove depth of described first ring connected in star and the second annular groove equates.Can reduce whole weight, reduce costs.
In above-mentioned driven three gear teeth, described gear mass is made by metallic material.The metallic material here comprises 20CrMnTiH.
Compared with prior art, the advantage of these driven three gear teeth is: it is more reasonable, simple in structure to design, and the engagement of helical teeth tooth is good, the stability in the time of can improving transmission, and in addition, position structure can be easy for installation and removal, and the quality of product is relatively high; It is firm to locate.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
In figure, gear mass 1, teeth 11, axis hole 12, involute splines 13, first ring connected in star 1a, the second annular groove 1b.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, these driven three gear teeth comprise gear mass in the form of annular discs 1, optimized project, and the gear mass 1 is here made by metallic material, this metallic material comprises 20CrMnTi H, in addition, be provided with some teeth 11 at gear mass 1 edge, the stability for transmission can be improved the time, these teeth 11 are that helical teeth and quantity are 41, be provided with at gear mass 1 center the axis hole 12 that axially runs through described gear mass 1, in order to facilitate location and installation and dismounting, be provided with position structure on axis hole 12 hole walls.
Concrete, as shown in Figure 1, above-mentioned position structure comprises involute splines 13.Further, these involute splines 13 numbers of teeth are 28.In addition, in order to alleviate whole weight, be respectively equipped with first ring connected in star 1a and the second annular groove 1b on gear mass 1 bi-side, the groove depth of first ring connected in star 1a and the second annular groove 1b equates, has reduced feeding intake, and can reduce production costs.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as gear mass 1, teeth 11, axis hole 12, involute splines 13, first ring connected in star 1a, the second annular groove 1b, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
