Abstract
The utility model belongs to the technical field of agricultural mechanical devices, and particularly relates to a planetary gear for a cultivator. The planetary gear for the cultivator solves the technical problems that an existing planetary gear in the prior art is not reasonable in design, short in service life and the like. The planetary gear for the cultivator comprises a gear body with a plurality of evenly-distributed teeth, a center hole is formed in the center of the gear body, and a tooth groove is formed between every two adjacent teeth. The planetary gear for the cultivator is characterized in that at least one oil hole located in the tooth grooves and communicated with the center hole is formed in the gear body, at least one U-shaped oil groove is formed in one end of the gear body, the depth of the U-shaped oil groove is 0.2-0.4mm, and the width of the U-shaped oil groove is 0.2-0.4mm. Compared with the prior art, the planetary gear for the cultivator has the advantages of being reasonable in design and good in practicability; in addition, the planetary gear for the cultivator is suitable for being used in the long-time operation environment by the adoption of a lubricating oil conveying structure, and corresponds with the current trend of the technological development in the society.
Description
Technical field
The utility model belongs to the agricultural machinery technical field, especially relates to a kind of planetary pinion for ploughing machine.
Background technique
Ploughing machine 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.Planetary pinion: in Planetary Gear Transmission, make the gear of planetary motion, the main feature of Planetary Gear Transmission is that volume is little, and bearing capacity is large, and the characteristics such as stable working are widely used in various machineries.There is following shortcoming the planetary pinion that existing ploughing machine is used in it: after long-time the use, between itself and sun gear, friction factor is large, reason is, lack lubricated between all the other sun gears, cause teeth and the friction between planetary teeth of sun gear to increase, virtually shortened working life.
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 reducing gear planet wheel [application number: 200520106659.1], and the engagement of this planetary pinion central gear inboard with it is rotated, and meshes and drive ring gear with the ring gear in its outside and rotate to form reducing gear; Planet wheel is protruding arc shape with the profile of tooth that central gear contacts with ring gear, and the position that the arc shape of projection is meshed with its internal gear and ring gear is the summit of its arc shape.
Such scheme has improved prior art to a certain extent, but this planetary pinion still exists working life short, is not suitable for the environment of long operation, and lubrication effect is poor.
The model utility content
The purpose of this utility model is for the problems referred to above, and a kind of long service life and the planetary pinion that is used for ploughing machine that is applicable to the long working environment are provided.
For achieving the above object, the utility model has adopted following technical proposal: this planetary pinion that is used for ploughing machine comprises the gear body with some even distribution teeth, be provided with center hole at gear body center, form teeth groove between two adjacent teeth, it is characterized in that, described gear body is provided with the oilhole that at least one is positioned at described teeth groove and is communicated with described center hole, an end at the gear body is provided with at least one U-shaped oil groove, the groove depth of described U-shaped oil groove is 0.2mm～0.4mm, and groove width is 0.2mm～0.4mm.Obviously, the utility model design is more reasonable, practical, and in addition, it has the lubricant oil structure for conveying, can be applicable to the environment of long working, meets the trend of current social technical development.
At the above-mentioned planetary pinion that is used for ploughing machine, described center hole two ends have respectively chamfering.The convenient installation.
The planetary pinion that is used for ploughing machine above-mentioned is respectively equipped with chamfer surface at the two ends of each teeth.
The planetary pinion that is used for ploughing machine above-mentioned has the plane at the top of each teeth.Contact ratio is good.
At the above-mentioned planetary pinion that is used for ploughing machine, described center bore inner wall roughness is Ra0.8.
At the above-mentioned planetary pinion that is used for ploughing machine, described chamfering is 1.5 * 30 °.The convenient installation.
Compared with prior art, this planetary advantage that is used for ploughing machine is: it is more reasonable, practical to design, and in addition, it has the lubricant oil structure for conveying, can be applicable to the environment of long working, meets the trend of current social technical development.
