Abstract
The utility model belongs to the technical field of sun wheels, and particularly relates to a last stage sun wheel. The last stage sun wheel solves the problems that a sun wheel in the prior art is not reasonable in design, poor in practicality and the like. The last stage sun wheel comprises a gear body, wherein a plurality of teeth are evenly distributed on the circumference, a central hole is formed in the axial center of the gear body, an annular locating step is arranged at one end of the gear body, one end, close to the annular locating step, of each tooth is provided with a first chamber face, and one end, away from the chamber face, of each tooth is provided with a limit step. Compared with the prior art, the last stage sun wheel has the advantages of being simple in structure and easy to manufacture. In addition, the last stage sun wheel is easy to install and locate and firm to fix. Practicality of the last stage sun wheel is virtually reinforced, and working stability of a whole machine can be ensured.
Description
Technical field
The utility model belongs to the sun gear technical field, especially relates to a kind of final stage sun gear.
Background technique
In the Planetary Gear Transmission, with the external gear of the same axis of planet carrier.The final stage sun gear generally comprises the gear body with some even distribution teeth, and gear body center is provided with center hole; Existing final stage sun gear is difficult between final stage sun gear and the axle installing when installing, and and planet axis between fixing not firm, virtually reduced work and manufacturing efficiency, be difficult for being applied.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of planetary type gear transmission unit [application number: 200920230289.0], at least comprise sun gear, planet wheel and planet carrier, planet carrier is milled with U-shaped groove, sun gear has the pin shaft hole that is complementary with U-shaped groove, pin shaft hole is tangent with row U-groove bevel face, is flexibly connected by bearing pin between planet carrier and the sun gear, and pin roll end face is provided with for radially spacing bearing or baffle plate.Above-mentioned scheme has been improved prior art to a certain extent, but at least also there is following defective in this scheme: be difficult for installing and the location, easy sideslip during installation has reduced production and working efficiency.
The model utility content
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, is easy to the final stage sun gear of installing and locating.
For achieving the above object, the utility model has adopted following technical proposal: this final stage sun gear comprises the gear mass with some even circumferential distribution teeth, be provided with center hole in the gear mass axial centre, it is characterized in that, described gear mass one end is provided with the circular orientation step, be respectively equipped with the first chamfer surface in each teeth near an end of circular orientation step, be respectively equipped with limited step in each teeth away from an end of chamfer surface.Obviously, the utility model design is more reasonable, simple in structure, and makes easily, in addition, the utility model is easy to install and the location, and is fixing very firm, virtually strengthen the practicability of this model utility, can guarantee the stability of complete machine work, met the trend of current social technical development.
In above-mentioned final stage sun gear, be provided with the ring-shaped step that is positioned at its place, aperture, two ends in the described center hole.The convenient installation.
In above-mentioned final stage sun gear, describedly be provided with the second chamfer surface in each teeth away from an end of chamfer surface.The convenient installation.
Compared with prior art, the advantage of this final stage sun gear is: it is more reasonable to design, simple in structure, and make easily, in addition, the utility model is easy to install and the location, fixing very firm, virtually strengthen the practicability of this model utility, can guarantee the stability of complete machine work, met 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 A place structural representation among Fig. 1.
Among the figure, gear mass 1, teeth 11, the first chamfer surface 11a, limited step 11b, the second chamfer surface 11c, center hole 12, ring-shaped step 12a, circular orientation step 13.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, this final stage sun gear comprises the gear mass 1 with some even circumferential distribution teeth 11, be provided with center hole 12 in gear mass 1 axial centre, be provided with circular orientation step 13 at gear mass 1 one ends, end at each teeth 11 close circular orientation step 13 is respectively equipped with the first chamfer surface 11a, be respectively equipped with limited step 11b in each teeth 11 away from the end of the first chamfer surface 11a, be provided with the second chamfer surface 11c in each teeth 11 away from the end of the first chamfer surface 11a.Obviously, the present embodiment design is more reasonable, simple in structure, and makes easily, in addition, the utility model is easy to install and the location, and is fixing very firm, virtually strengthen the practicability of this model utility, can guarantee the stability of complete machine work, met the trend of current social technical development.
Specifically, be provided with the ring-shaped step 12a that is positioned at its place, aperture, two ends in the present embodiment center hole 12.
Specific embodiment described herein only is 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, the first chamfer surface 11a, limited step 11b, the second chamfer surface 11c, center hole 12, ring-shaped step 12a, circular orientation step 13, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
