Technical field
The utility model belongs to the agricultural machinery technical field, especially relates to a kind of self-lubricating type duplicate gear of cultivator special use.
Background technique
Along with the continuous progress of society, mechanization and automation replacing manual mode of operation in the past, it is high that mechanization and automation have manufacturing efficiency, reduces labor intensity etc. advantage, and it plays important position in modern agricultural production.Existing agricultural machinery generally has: cultivator and transplanter etc. are at interior equipment, and cultivator is to complete cultivation machinery cultivated, the rake operation with tractor.Because of its have the hack ability strong, plough after the characteristics such as earth's surface is smooth, and be widely used.The duplicate gear of existing cultivator has following shortcoming: design unreasonablely, structural strength is low, secondly, its after long-time the use, between the part coordinated with it owing to lacking lubricant oil, serious wear, duplicate gear and the part coordinated with it all easily damage, thereby have increased user cost.
The problem existed 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 dual gear Improved structure [application number: 200620140475.1], the first rank gear of duplicate gear and second-order gear joint also are provided with the stiffening rib of cabochon, described stiffening rib is located between each tooth of the first rank gear, and it is external boundary that the stiffening rib root be take the tip diameter of the first rank gear.
Such scheme has improved the subproblem of prior art to a certain extent, but still exist: design unreasonablely, between the part that gear is mated, lubrication effect is poor, and the oil storage capacity of self is poor, the long-time later stage serious wear of using, reduced the technical problems such as complete machine working stability.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, has self-lubricating structure, the self-lubricating type duplicate gear of the cultivator special use of high lubricating effect.
For achieving the above object, the utility model has adopted following technical proposal: the self-lubricating type duplicate gear of this cultivator special use, comprise that two ends have the gear mass of the first tooth section and the second tooth section, be provided with center hole in the gear mass axial centre, it is characterized in that, the described gear mass outside is provided with annular protrusion, forms the first circular groove between described annular protrusion and the first tooth section, form the second circular groove between annular protrusion and the second tooth section, be provided with the spiral oil storage tank in described center hole.Obviously, the utility model design is more reasonable, and the spiral oil storage tank can be used for storing lubricant oil, it can needn't add lubricant oil at certain hour, has reduced the friction factor between component, in addition, this structure is effective from moistening, and has extended working life, meets the trend of current social technical development.
In the self-lubricating type duplicate gear of above-mentioned cultivator special use, described spiral oil storage tank comprises one or both the combination in right-handed screw groove and backpitch groove.
In the self-lubricating type duplicate gear of above-mentioned cultivator special use, the groove depth of described spiral oil storage tank is 1mm～3mm, and groove width is 1mm～3mm, and the pitch of grooves of two adjacent grooves is 1mm～6mm.
In the self-lubricating type duplicate gear of above-mentioned cultivator special use, each teeth two ends of described the first tooth section are respectively equipped with the first chamfer surface, at each teeth two ends of the second tooth section, are respectively equipped with the second chamfer surface.
In the self-lubricating type duplicate gear of above-mentioned cultivator special use, described center hole two ends are respectively equipped with chamfering.
Compared with prior art, the advantage of the self-lubricating type duplicate gear of this cultivator special use is: it is more reasonable to design, the spiral oil storage tank can be used for storing lubricant oil, it can needn't add lubricant oil at certain hour, reduced the friction factor between component, in addition, this structure is effective from moistening, extend working life, met the trend of current social technical development.
