Abstract
The present invention discloses a kind of epicyclic speed reducer, it includes housing, the input shaft for being arranged on the housing input terminal, the output shaft for being arranged on the housing output terminal, it further includes and is arranged on the in vivo cycloid gear transmission mechanism of the shell and epicyclic transmission mechanism, since the present invention will be together with cyclo drive and planet gear transmission high effective integration, speed reducer is enabled to have on the premise of small volume, and gearratio is big, the high technological merit of load.
Description
Technical field
The present invention relates to a kind of epicyclic speed reducers.
Background technology
Existing speed reducer species has the variety classeses such as cyclo drive and planet gear transmission, and cycloidal planetary gear speed reducer has knot
Structure is compact, the advantages that being hardly damaged, but cannot be too big there are load, and central shaft is easily disconnected, the defects of dismounting trouble, and goes
The load that star speed reducer can carry is larger, but there are structure inadequate compact transmission distance it is longer the defects of, be unsuitable to apply to
The limited situation of installation volume.
Therefore, need a kind of installation volume smaller at present, bigger and with stronger load capacity the speed reducer of transmission.
The content of the invention
The object of the present invention is to provide a kind of installation volume is smaller, transmission is bigger and slows down with stronger load capacity
Machine.
In order to achieve the above objectives, the technical solution adopted by the present invention is：
A kind of epicyclic speed reducer including housing, is arranged on the input shaft of the housing input terminal, is arranged on the housing
The output shaft of output terminal further includes and is arranged on the in vivo cycloid gear transmission mechanism of the shell and epicyclic transmission mechanism, the pendulum
Line gear rotating mechanism includes eccentric bushing of the tool being set on the input shaft there are two eccentric wheel, is respectively sleeved at two institutes
The Cycloidal Wheel on eccentric wheel, the axis pin being connected with the outer ring rotating of the Cycloidal Wheel, the cycloid output panel of the fixed axis pin are stated,
And the cycloid output shaft being mutually fixedly installed with the cycloid output panel, the epicyclic transmission mechanism include being arranged on the cycloid
Sun gear on output shaft, the planet carrier being fixedly linked with the output shaft, the gear ring for being arranged on the inner walls, Yi Jizhuan
It is dynamic to be arranged on the planetary gear being meshed on the planet carrier while with the sun gear and the gear ring.
Preferably, the support portion for supporting the cycloid output shaft is provided in the housing, the support portion passes through bearing
Support and the cycloid output shaft.
It is further preferred that the support portion extends circlewise from the inner wall of the housing to center, inner edges portion tool
The abutting portion of oriented both sides protrusion.
It is further preferred that the support portion is shaped with the housing integrally casting.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
Since the present invention is by together with cyclo drive and planet gear transmission high effective integration, speed reducer is enabled in small volume
Under the premise of have gearratio it is big, the high technological merit of load.
Description of the drawings
Attached drawing 1 is schematic diagram of the invention.
In the figures above：1st, housing；2nd, input shaft；3rd, output shaft；4th, eccentric bushing；5th, Cycloidal Wheel；6th, axis pin；7th, the sun
Wheel；8th, planet carrier；9th, gear ring；10th, planetary gear；11st, support portion.
Specific embodiment
The invention will be further described for shown embodiment below in conjunction with the accompanying drawings：
Referring to shown in attached drawing 1, a kind of epicyclic speed reducer, including housing 1, be arranged on 1 input terminal of housing input shaft 2,
The output shaft 3 of 1 output terminal of housing is arranged on, further includes the cycloid gear transmission mechanism being arranged in housing 1 and Gear Planet Transmission machine
Structure, cycloid gear rotating mechanism include eccentric bushing 4 of the tool being set on input shaft 2 there are two eccentric wheel, are respectively sleeved at two
Cycloidal Wheel 5 on a eccentric wheel, the axis pin 6 being connected with the outer ring rotating of Cycloidal Wheel 5, fixed pin shaft 6 cycloid output panel and
The cycloid output shaft being mutually fixedly installed with cycloid output panel, epicyclic transmission mechanism include the sun gear being arranged on cycloid output shaft
7th, the planet carrier 8 that is fixedly linked with output shaft 3 is arranged on the gear ring 9 of 1 inner wall of housing and is rotatably arranged on planet carrier 8 same
When the planetary gear 10 that is meshed with sun gear 7 and gear ring 9.
The support portion 11 of support cycloid output shaft is provided in housing 1, support portion 11 is exported by bearings and cycloid
Axis.
Support portion 11 extends circlewise from the inner wall of housing 1 to center, and inner edges portion has the conflict to both sides protrusion
Portion.
Support portion 11 is shaped with 1 integrally casting of housing.
Since the present embodiment is by together with cyclo drive and planet gear transmission high effective integration, speed reducer is enabled in volume
It is big with gearratio under the premise of smaller, the high technological merit of load.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and implement according to this, and it is not intended to limit the scope of the present invention.It is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should be covered by the protection scope of the present invention.
