Abstract
The utility model relates to a planet carrier which comprises a planet carrier body, wherein the planet carrier body is a circular cylinder; one end of the planet carrier body is connected with an output shaft, and the other end of the planet carrier body is provided with an installation boss; the planet carrier body is internally provided with a communication cavity one end of which is provided with an opening, and the opening is positioned on one end of the installation boss arranged on the planet carrier body; and the side wall of the communication cavity is uniformly provided with at least three installation cavities used for installing a planetary wheel, and the installation cavities penetrate through the planet carrier body so as to communicate with the communication cavity along a radial direction. By adopting the structure, the two ends of the planet carrier body are utilized as a support, and the planet carrier provided by the utility model has the advantages of good rigidity, long service life and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of planetary gears, relates in particular to a kind of planet carrier.
Background technique
Existing planet carrier mainly comprises connecting body and the planet support body that is connected with this connecting body, and this planet support body is a disk, is evenly equipped with at least 3 planet bearing pins on the end face of this planet support body, and this planet bearing pin is set with planet wheel outward.When planet carrier was installed, the planet support body generally through connecting the extracorporeal set bearing, constituted the cantilever installation thereby form the strong point with bearing, and this just requires connecting body to have very high intensity, thereby has increased the manufacture cost of planet carrier, and simultaneously, working life is short.
Summary of the invention
Have above-mentioned deficiency in the existing technology in order to overcome, the utility model provides the planet carrier of a kind of simple and compact for structure, two end supports, low cost of manufacture, long service life.
The technological scheme that the utility model solves its technical problem is: a kind of planet carrier; Comprise the planet support body; Said planet support body is a cylindrical body, and an end of said planet support body is connected with output shaft, and the other end of said planet support body is provided with installation base; Be provided with vertically in the said planet support body one have an end opening the ditch cavity; Said opening is positioned on the end that said planet support body has said installation base, is evenly equipped with at least 3 installation cavitys that planet wheel can be installed on the sidewall of said ditch cavity, and this installation cavity radially runs through said planet support body and is connected with said ditch cavity.
Further, said planet support body and said output shaft are processed one.
The utility model in use; The planet carrier extracorporeal set has internal gear, and sun gear is packed into through the opening on the planet support body in the ditch cavity, and planet wheel is rotating to be installed in the installation cavity; And the part that planet wheel the stretches out installation cavity transmission that is meshed with internal gear; Planet wheel stretches into a part and the sun gear engagement driving in the ditch cavity, and load onto bearing and support at installation base and output shaft overcoat then through bearing, thus the two end supports of realization planet support body.
The beneficial effect of the utility model is: 1. adopt said structure, the planet support body is a two end supports, makes the good rigidly of the utility model, long service life, low cost of manufacture.2. because planet support body and output shaft are processed one, make that the utility model structure is simpler.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, a kind of planet carrier comprises planet support body 1; Said planet support body 1 is a cylindrical body; One end of said planet support body 1 is connected with output shaft 2, and said planet support body 1 processes one with said output shaft 2, and the other end of said planet support body 1 is provided with installation base 3; Be provided with vertically in the said planet support body 1 one have an end opening 4 ditch cavity 5; Said opening 4 is positioned on the end that said planet support body 1 has said installation base 3, is evenly equipped with at least 3 installation cavitys 6 that planet wheel can be installed on the sidewall of said ditch cavity 5, and this installation cavity 6 radially runs through said planet support body 1 and is connected with said ditch cavity 5.
The utility model in use; The outer internal gear that is set with of planet support body 1, sun gear are packed into through the opening on the planet support body 14 in the ditch cavity 5, and planet wheel is rotating to be installed in the installation cavity 6; And the part that planet wheel stretches out installation cavity 6 transmission that is meshed with internal gear; Planet wheel stretches into a part and the sun gear engagement driving in the ditch cavity 5, and load onto bearing 7 and support at installation base 3 and output shaft 2 overcoats then through bearing 7, thus the two end supports of realization planet support body 1.Adopt said structure, planet support body 1 is a two end supports, makes the good rigidly of the utility model, long service life, low cost of manufacture.And planet support body 1 is processed one with output shaft 2, makes that the utility model structure is simpler.
Claims (2)
1. planet carrier; Comprise the planet support body; It is characterized in that: said planet support body is a cylindrical body, and an end of said planet support body is connected with output shaft, and the other end of said planet support body is provided with installation base; Be provided with vertically in the said planet support body one have an end opening the ditch cavity; Said opening is positioned on the end that said planet support body has said installation base, is evenly equipped with at least 3 installation cavitys that planet wheel can be installed on the sidewall of said ditch cavity, and this installation cavity radially runs through said planet support body and is connected with said ditch cavity.
