Abstract
The utility model relates to a planetary differential gear speed reducer, wherein, the housing is composed of a box body, a coupling flange, and an end cover, a motor is fixed to the coupling flange through a bolt, the inner transmission is composed of two parts of a planetary gear transmission and a differential gear transmission, and the input shaft is connected with the duplex sun wheel. In the planetary gear transmission part, the planetary frame is fixed to the housing of the speed reducer, the sun wheel drives the duplex internal gear to rotate through the planetary wheel, and a component velocity is formed; in the differential gear transmission part, the sun wheel and the duplex internal gear are engaged with the planetary wheel simultaneously to carry out composition of velocity, and the compound speed can be output through an output shaft with a planetary frame.
Description
The utility model relates to a kind of epicyclic transmission mechanism, particularly a kind of planet differential retarder.
In the planetary pinion transmission at present commonly used, advantage such as NGW type planetary pinion transmission application is the widest, and this transmission is made up of input shaft, sun gear, planet carrier, planet wheel, internal gear and output shaft, has the efficient height, and volume is little, and is simple in structure, and transmitted power is big.But NGW type plane table thermoconductivity meter single staged transmission ratio scope is little, when requiring velocity ratio greater than 12.5 the time, can only adopt multistage transmission, and efficient reduces like this, and volume increases, complex structure.
The purpose of this utility model is that a kind of velocity ratio of design is in tens to several ten thousand scopes, than the more excellent planet differential retarder of multistage NGW type plane table thermoconductivity meter performance.
The purpose of this utility model is achieved in that the inner transmission of retarder partly is made up of planetary pinion transmission and differential gear transmission two, motor reel connects with the duplex sun gear, and drive duplex sun gear rotates synchronously, in the planet gear transmission partly, planet carrier is fixed on the retarder shell, sun gear drives the duplex internal gear by planet wheel and rotates, and forms a component velocity; In the differential gear driving section, sun gear and duplex internal gear mesh with planet wheel simultaneously, carry out the synthetic of speed, and synthetic speed is exported by the output shaft of band planet carrier.Difference as two speed of decomposing goes to zero, and then He Cheng speed also goes to zero, and promptly the velocity ratio of planet differential gear retarder is tending towards infinity.
Below in conjunction with embodiment the utility model is further specified:
Fig. 1 is planet differential retarder embodiment's a sectional view.
The retarder shell is made up of casing (1), tie-plate (2), end cap (3).Motor (4) is fixed by bolts on the tie-plate (2), and the spline axle head of motor (5) meshes with the internal spline (8) of duplex sun gear (6), (7).In the planet gear transmission partly, planet carrier (9) is an integral body with tie-plate (2).Sun gear (6) drives duplex internal gear (11), (12) rotation by planet wheel (10), forms a component velocity.Floating by simply connected gear coupling (13) in duplex internal gear (11), (12), all carries purpose to reach.In the differential gear driving section, sun gear (7) and internal gear (12) mesh with planet wheel (14) simultaneously, carry out the synthetic of speed, and synthetic speed is exported by the output shaft (15) of band planet carrier.
Claims (2)
1, a kind of planet differential retarder, shell is made up of casing, tie-plate, end cap, and motor is fixed by bolts on the tie-plate; Planet differential driving section in the retarder is made up of sun gear, planet carrier, planet wheel, internal gear, output shaft, and it is characterized in that: sun gear is the duplex sun gear.
2, planet differential retarder according to claim 1 is characterized in that: internal gear is the duplex internal gear.
