Abstract
Reductor is the utility model is related to, more particularly to a kind of general tie-rod reductor of planetary gear.It includes sun gear, planetary gear, planet axis, internal gear and double-walled planet carrier, it is characterized in that chute is radially provided with the former of the double-walled planet carrier, floating slider is provided with the chute, the planet axis both ends are fixedly connected with the left and right floating slider.Its purpose is to design a kind of general tie-rod reductor of planetary gear for reducing machining accuracy control and requiring.Compared with prior art, there is the relatively easy control of processing, installed and used suitable for multiple gearratios, the advantages that planet carrier is converted to general part.
Description
Technical field
Reductor is the utility model is related to, more particularly to a kind of general tie-rod reductor of planetary gear.
Background technology
Planetary reducer is a kind of widely used reductor, and its primary drive structure includes sun gear, planetary gear
Group, internal gear and planet carrier, sun gear are located at internal gear center, and planetary gearsets are combined in planet carrier by three planetary gear deciles
On.Its weak point：
1st, planet carrier installs planetary gear using Triaxial hole, need to control the circumferential precision with radially two directions, processing is relatively
Difficulty, and circumferential error and radial error can all influence the uniformity of three planetary gear carryings, cause some planetary gear to overload, drop
Low integrated carrying ability.
2nd, planet carrier Triaxial hole is radially fixed, and the centre-to-centre spacing equivalent to gear pair is fixed, and is typically only used for a kind of transmission
Than multiple gearratios then need to design multiple planet carriers.
The content of the invention
The purpose of this utility model, which is that design is a kind of, reduces the general tie-rod deceleration of planetary gear that machining accuracy control requires
Machine.
In order to achieve the above object, the utility model uses following technical solution：A kind of general tie-rod of planetary gear
Reductor, it includes sun gear, planetary gear, planet axis, internal gear and double-walled planet carrier, it is characterised in that in the double-walled row
Chute is radially provided with the former of carrier, floating slider, the planet axis both ends and left and right institute are provided with the chute
Floating slider is stated to be fixedly connected.
The utility model is further set to limit the axial float of planet axis to the technical scheme：Institute
State floating slider side and be provided with sliding block axially position block, the sliding block axially position block is fixed in the planet axis, the cunning
The diameter of block axially position block is more than the width of the chute.
Brief description of the drawings
Fig. 1 is the present embodiment section of structure.
Fig. 2 is sectional views of the Fig. 1 along B-B directions.
Fig. 3 is sectional views of the Fig. 1 along C-C directions.
Fig. 4 is sectional views of the Fig. 1 along A-A directions.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Fig. 1, Fig. 3, Fig. 4, the present embodiment includes sun gear 7, planetary gear 4, planet axis 3, internal gear 8 and double-walled
Planet carrier 1, chute 6 is radially provided with the former 9 of the double-walled planet carrier 1, floating slider 2 is provided with the chute 6,
The both ends of planet axis 3 are fixedly connected with the left and right floating slider 2.Each planet axis 3 is in sun gear 7, planetary gear 4, interior
Moved radially under the mutual engagement force effect of gear 8, change the centre-to-centre spacing between planetary gear and sun gear 7, make row
Star gear train 4 is in the optimum position carried.
As shown in Figure 1 and Figure 2, in order to limit the axial float of planet axis, sliding block axle is provided with the side of floating slider 2
To locating piece 5, the sliding block axially position block 5 is fixed in the planet axis 3, and the diameter of the sliding block axially position block 5 is big
In the width of the chute 6.
In summary, the utility model has the advantage that compared with prior art：
1st, the relatively easy control of processing.It is one-dimensional because the positional precision of planet carrier axis hole is controlled by Simplified two-dimension, only needs
Circumferential precision is controlled, processes relatively easy control.
2nd, the maximum load-carrying capacity of each gear can be played.Planetary gear can be made radially floating by mutual force-bearing situation
It is dynamic, reach uniform force, planetary gear set is in the optimum position carried, the maximum load-carrying capacity of each gear can be played.
3rd, multiple gearratios are applicable to install and use.The radially movable change centre-to-centre spacing of planet axis, makes planet carrier to fit
For installing and using for multiple gearratios, the planet carrier of conversion is converted into general part.
