Abstract
The utility model belongs to the technical field of agricultural machinery and equipment, and particularly relates to a connecting gear for a cultivator. The connecting gear for the cultivator solves the technical problems that in the prior art, the design is not reasonable enough, and the service life is short. The connecting gear for the cultivator comprises a shaft body, and is characterized by comprising a gear body with a plurality of evenly-distributed teeth, a center hole is formed in the center of the gear body, a connecting column is arranged at one end of the gear body, a connecting hole which is communicated with the center hole is formed in the connecting column, the center line of the connecting hole coincides with the center line of the center hole, an internal spline is arranged on the inner wall of the connecting hole, and the height of the connecting column is larger than that of the gear body. Compared with the prior art, the connecting gear for the cultivator has the advantages of being more reasonable in design, easy to assemble and disassemble, high in integral structural strength, good in practicability and easy to manufacture.
Description
Technical field
The utility model belongs to the agricultural machinery technical field, especially relates to a kind of cultivator with connecting gear.
Background technique
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.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, is widely used in the every field in production, life.As everyone knows, gear is the vitals in transmission device, connecting gear is a kind of component of small volume, and it must have the structural strength advantages of higher as a kind of link, there is following shortcoming in existing connection gear, bearing capacity is relatively poor, the manufacture process more complicated, in addition, its working life is shorter, has virtually increased user cost.
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: 91211805.9], and a kind of gear that is comprised of tooth, gear mass etc. is characterized in that, described tooth is two helical teeth, and the two ends of gear mass are provided with the bearing attachment face.This scheme can improve the advantages such as service behaviour of complete machine, but its bearing capacity of the gear of this scheme is relatively poor, moreover, connect inconvenience, make installation and removal all have very large production problem.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of bearing capacity good, and structural strength is high, and the cultivator of the clutch speed that can enhance productivity is with connecting gear.
For achieving the above object, the utility model has adopted following technical proposal: this cultivator comprises axle body with the connection gear, it is characterized in that, this connection gear comprises the gear mass with some even distribution teeth, be provided with center hole at the gear mass center, be provided with attachment post at an end of gear mass, described attachment post is provided with the attachment hole that overlaps with the center hole center line with center hole connection and center line, be provided with internal spline on the attachment hole inwall, described attachment post height is greater than the height of gear mass.Obviously, the utility model design is more reasonable, mount and dismount all fairly simplely, and whole structural strength is high, and practicability is stronger, and in addition, easily manufacturing meets the trend of current social technical development.
With in connecting gear, described gear mass is provided with chamfer surface near an end of attachment post at above-mentioned cultivator.The convenient installation.
At above-mentioned cultivator with in connecting gear, described gear mass and the attachment post formula that is connected as a single entity.Structural strength is high.
Use in the connection gear the curved helical teeth structure of described teeth at above-mentioned cultivator.Power output is steady, and structural strength is high.
With in connecting gear, the surface roughness of each teeth is Ra1.6 at above-mentioned cultivator.
With in connecting gear, described internal spline surface roughness is Ra1.6 at above-mentioned cultivator.
Compared with prior art, this cultivator is with the advantage that connects gear: it is more reasonable design, mount and dismount all fairly simplely, and whole structural strength is high, and practicability is stronger, and in addition, easy manufacturing meets the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
In figure, gear mass 1, teeth 11, chamfer surface 12, attachment post 2, attachment 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 Figure 1, this cultivator comprises the gear mass 1 with some even distribution teeth 11 with the connection gear, the curved helical teeth structure of each teeth 11, and the surface roughness of each teeth 11 is Ra1.6, be provided with center hole at gear mass 1 center, an end at gear mass 1 is provided with attachment post 2, described attachment post 2 is provided with the attachment hole 21 that overlaps with the center hole center line with center hole connection and center line, be provided with internal spline 21a on attachment hole 21 inwalls, this internal spline 21a surface roughness is Ra1.6, and described attachment post 2 height are greater than the height of gear mass 1.Obviously, the present embodiment design is more reasonable, mount and dismount all fairly simplely, and whole structural strength is high, and practicability is stronger, and in addition, easily manufacturing meets the trend of current social technical development.
Specifically, the gear mass 1 of the present embodiment is provided with chamfer surface 12 near an end of attachment post 2.In order to improve join strength, the gear mass 1 here and attachment post 2 formula that is connected as a single entity.In addition,
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, chamfer surface 12, attachment post 2, attachment hole 21, internal spline 21a, 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.
