Abstract
The utility model belongs to the technical field of agricultural machinery and equipment, and particularly relates to a high-strength gear for a cultivator. The high-strength gear for the cultivator solves the technical problem that in the prior art, the design is not reasonable enough. The high-strength gear for the cultivator comprises a gear body with a plurality of evenly-distributed teeth. The high-strength gear for the cultivator is characterized in that a connecting body is arranged at one end of the gear body, a shaft hole is formed in the axial center of the gear body, a center hole is formed in the axial center of the connecting body, the center line of the center hole coincides with the center line of the shaft hole, an annular step is arranged on the hole opening of one end, far away from the connecting body, of the interior of the shaft hole, and the height of the annular step is smaller than that of the gear body. Compared with the prior art, the high-strength gear for the cultivator has the advantages of being more reasonable in design, long in service life and high in structural strength. In addition, due to the fact that the high-strength gear for the cultivator is simple in structure, the manufacturing process is simple, and production cost is reduced.
Description
Technical field
The utility model belongs to the agricultural machinery technical field, especially relates to a kind of high strength gear of cultivator special use.
Background technique
As everyone knows, gear is the vitals in transmission device, and gear is a kind of common mechanical parts, and its structural type is varied, as various forms such as spur wheel, angular gear, bevel gear, worm screws, be widely used in the every field in production, life.Cultivator is to complete cultivation machinery cultivated, the rake operation with tractor.Because it has the characteristics such as the hack ability is strong, cultivated rear earth's surface is smooth, and be widely used.Mostly Placement between gear generally is the intermeshing structure of teeth, it is high that it has a velocity ratio, the advantages such as connective stability is good, at present, in existing cultivator, connecting gear is a kind of important connected element, it can output power, and the gear of existing cultivator special use generally has following shortcoming, is difficult for installing and the location, unloading process is comparatively loaded down with trivial details, and manufacture cost is higher.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of gear [application number: 200720159453.4], comprises gear shaft, key, it is characterized in that being arranged on gear shaft through key by a plurality of spur gear sheets, the spur gear sheet is successively around axial-rotation, and the tooth between adjacent straight gear sheet is interlaced.
Such scheme has improved the subproblem of prior art to a certain extent, but still exists: manufacture process is loaded down with trivial details, and complex structure and manufacture cost are than the high-technology problem.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, the high strength gear of the cultivator special use of simple in structure and low cost of manufacture.
For achieving the above object, the utility model has adopted following technical proposal: the high strength gear of this cultivator special use, comprise the gear body with some even distribution teeth, it is characterized in that, described gear body one end has connecting body, axial centre at the gear body is provided with axis hole, axial centre at connecting body is provided with center hole, described center hole center line overlaps with the axis hole center line, a stomidium mouth place that is positioned in axis hole away from connecting body is provided with ring-shaped step, and described ring-shaped step height is less than the height of gear body.Obviously, the utility model design is more reasonable, and structural strength is high, and in addition, it is simple in structure, and manufacture process is just fairly simple like this, thereby has reduced cost of production, meets the trend of current social technical development.
In the high strength gear of above-mentioned cultivator special use, be provided with position structure in described center hole.The convenient installation and the location.
In the high strength gear of above-mentioned cultivator special use, described position structure comprises the internal spline that is arranged on center bore inner wall.Easily make, cost is low and manufacturing efficiency is high.
In the high strength gear of above-mentioned cultivator special use, the tapered body of described connecting body.Save material and can satisfy usage requirement simultaneously.
In the high strength gear of above-mentioned cultivator special use, be respectively equipped with chamfer surface at the two ends of each teeth.
In the high strength gear of above-mentioned cultivator special use, the described internal spline number of teeth is six teeth.
In the high strength gear of above-mentioned cultivator special use, described connecting body and the gear body formula that is connected as a single entity.Structural strength is high.
Compared with prior art, the advantage of the high strength gear of this cultivator special use is: it is more reasonable to design, long service life, structural strength is high, and in addition, it is simple in structure, manufacture process is just fairly simple like this, thereby has reduced cost of production, meets the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Fig. 2 is the broken section structural representation that the utility model provides.
In figure, gear body 1, teeth 11, chamfer surface 11a, axis hole 12, ring-shaped step 13, connecting body 2, center hole 21, internal spline 21a.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
as shown in Fig. 1-2, the high strength gear of this cultivator special use comprises the gear body 1 with some even distribution teeth 11, be respectively equipped with chamfer surface 11a at the two ends of each teeth 11, has connecting body 2 at gear body 1 one ends, the tapered body of this connecting body 2, in order to improve join strength, optimized project, the connecting body 2 here and gear body 1 formula that is connected as a single entity, axial centre at gear body 1 is provided with axis hole 12, axial centre at connecting body 2 is provided with center hole 21, described center hole 21 center lines overlap with axis hole 12 center lines, a stomidium mouth place that is positioned in axis hole 12 away from connecting body 2 is provided with ring-shaped step 13, described ring-shaped step 13 height are less than the height of gear body 1.Obviously, the present embodiment design is more reasonable, long service life, and structural strength is high, and in addition, it is simple in structure, and manufacture process is just fairly simple like this, thereby has reduced cost of production, meets the trend of current social technical development.
Specifically, be provided with position structure in the center hole 21 of the present embodiment.Optimized project, the position structure here comprise the internal spline 21a that is arranged on center hole 21 inwalls.The internal spline 21a number of teeth of the present embodiment is six teeth.
