Abstract
The utility model discloses a kind of planet carrier structures, it include the upper mounting plate and lower installation board and the supporter between it that casting is integrated, centre bore and planet hole are respectively equipped on the upper and lower mounting plate, using equipped with rounded corners transition between the supporter and upper and lower mounting plate, the lower end surface of the upper mounting plate, the upper surface of lower installation board are respectively equipped with the home record boss shifted to install with planet hole, and the cross sectional shape of the supporter is flaabellum shape.The structure design of the utility model is reasonable, by the structure snd size for changing supporter, it reduces the size on its basis, it can guarantee its integrally-built stability, it ensure that enough spaces are conducive to assembly, ensure that product service performance, and effectively prevent interference phenomenon generation and stress and phenomenon of rupture occurs.
Description
Technical field
The utility model relates to planetary reduction gear fields, relate generally to a kind of planet carrier structure.
Background technique
Planet carrier is that common structure form has dual-sided board monoblock type, dual-sided board split and board-like three kinds of unilateral side.It is existing
Supporting body structure is simple, is mostly the arcuate structure being arranged in a circumferential direction, space is small to be inconvenient to assemble, and existing
There is no home record boss in product structure, welding is easy to cause deformation, the later period using when will lead to gear and product interference, to damage
Bad equipment uses right angle transition between supporter and upper and lower mounting plate, be easy stress and phenomenon of rupture occurs, influencing it makes
Use the service life.
Utility model content
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of planet carrier structure, passes through change
The structure snd size of supporter guarantee that enough spaces are conducive to assembly, can effectively prevent the generation of interference phenomenon.
The utility model is achieved through the following technical solutions:
A kind of planet carrier structure includes upper mounting plate and lower installation board and the support between it that casting is integrated
Body is respectively equipped with centre bore and planet hole on the upper and lower mounting plate, it is characterised in that: the supporter and upper and lower installation
Between plate using be equipped with rounded corners transition, the lower end surface of the upper mounting plate, the upper surface of lower installation board be respectively equipped with
The home record boss that planet hole shifts to install, the cross sectional shape of the supporter are flaabellum shape.
The angle of the rounded corners transition is 5-10 °.
The outer periphery face of the home record boss and the outer wheel face of planetary gear to be installed cooperate, the thickness of the home record boss
Less than upper mounting plate or lower installation board at a distance from the planetary gear inner face of respective side.
The fan angle of the supporter is 30 °.
The supporter part is between upper and lower mounting plate, and its fan-shaped thickness is slightly less than the outer of sun gear to be installed
Distance of the wheel face to supporter outer end.
Its principle is: by the structure of flaabellum shape supporter, reducing the size on its basis, it is ensured that its is integrally-built
Stability ensure that enough spaces are conducive to assembly, ensure that product service performance；Increasing home record boss can effectively prevent
The generation of interference phenomenon, the service life of the equipment of guarantee；Pass through the rounded corners mistake between upper and lower mounting plate and supporter
The structure crossed can increase switching performance and anti-fatigue performance between it, avoid its stress and phenomenon of rupture occurs.
The utility model has the advantages that:
The structure design of the utility model is reasonable, by the structure snd size of change supporter, reduces the size on its basis,
It can guarantee its integrally-built stability, that is, ensure that enough spaces are conducive to assembly, ensure that product service performance, Er Qieyou
Effect the generation for preventing interference phenomenon and stress and phenomenon of rupture occurs.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the main sectional view of Fig. 1.
Specific embodiment
Referring to attached drawing.
A kind of planet carrier structure includes upper mounting plate 1 and lower installation board 2 and the support between it that casting is integrated
Body 3, is respectively equipped with centre bore 4 and planet hole 5 on the upper and lower mounting plate, the supporter 3 and upper and lower mounting plate 1,2 it
Between using be equipped with 6 transition of rounded corners, the lower end surface of the upper mounting plate 1, the upper surface of lower installation board 2 be respectively equipped with row
The home record boss 7 that star hole shifts to install, the cross sectional shape of the supporter 3 are flaabellum shape.
The angle of 6 transition of rounded corners is 5-10 °.
The outer periphery face of the home record boss 7 and the outer wheel face of planetary gear to be installed cooperate, the thickness of the home record boss 7
Degree is less than upper mounting plate or lower installation board at a distance from the planetary gear inner face of respective side.
The fan angle of the supporter 3 is 30 °.
3 part of supporter is between upper and lower mounting plate, and its fan-shaped thickness is slightly less than the outer of sun gear to be installed
Distance of the wheel face to supporter outer end.
