Description
Technical field
The utility model relates to the antifriction of planetary reduction gear equipment technical field more particularly to a kind of new gear retarder
Structure.
Background technique
Retarder is a kind of drive apparatus, mainly utilizes the components such as gear by the rotation of the high revolving speed, small torque of input shaft
It is converted into the rotation of the output shaft slow-speed of revolution, large torque.In the mechanism currently used for transmitting power and movement, retarder is because of its tool
Have the advantages that small in size, light-weight, high-efficient and transmitting power bracket is big and has been more and more widely used.
And existing retarder is during the work time because retarder motor installation direction, axial gap, planet carrier and
Accuracy of gear etc. influences, and input shaft/end face between sun gear and planet carrier, between planetary gear and planet carrier can have friction,
And then the working efficiency of retarder is influenced, while also influencing the service life of components.
Utility model content
In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide it is a kind of can not be by
Precision influences that the antifriction knot that each components end face has the planetary reducer for rubbing and influencing efficiency can be released simultaneously
Structure.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of antifriction of planetary reducer
Structure is wiped, including motor input shaft, the planetary gear set with the transmission connection of motor input shaft, which includes the sun
Wheel, planetary gear and planet carrier, the planetary gear are rotatably arranged on planet carrier, and the sun gear and planetary gear engaged transmission are even
It connects, and is symmetrically provided with slot on the sun gear end face opposite with planet carrier, be provided with ball between the slot.
Further, the groove depth summation of described two symmetrical slots is less than the diameter of ball, to reach ball in not shadow
It avoids sun gear from contacting with planet carrier in the case where ringing sun gear rotation to cause to wear
Further, symmetrical auxiliary slot is provided in the planetary gear both ends of the surface opposite with planet carrier, this is symmetrical auxiliary
It helps between slot and is equipped with auxiliary ball, to make that ball is assisted to separate planetary gear and planet carrier, avoid planetary gear and planet bridge joint
Touching causes to wear.
Further, the groove depth summation of described two symmetrical auxiliary slots is less than the diameter of auxiliary ball.
Compared with the prior art, the advantages of the utility model are: the utility model use sun gear and planet carrier it
Between open up slot and put the structure of ball come reach guarantee planetary gear set operate normally rotation under the premise of avoid because manufacture
Precision problem influences working efficiency and causes to wear, and the utility model is designed reasonably accords with the demands of the market, and is suitble to promote.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of the utility model embodiment 1；
Fig. 2 is the diagrammatic cross-section of the utility model embodiment 2.
Including: motor input shaft 1, planetary gear set 2, sun gear 2-1, planetary gear 2-2 and planet carrier 2-3, slot
3, ball 4, auxiliary slot 5, auxiliary ball 6.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of antifriction structure of planetary reducer, including motor input shaft 1 and motor input shaft
The planetary gear set 2 of 1 transmission connection, the planetary gear set 2 include sun gear 2-1, planetary gear 2-2 and planet carrier 2-3, the row
Star-wheel 2-2 is rotatably arranged on planet carrier 2-3, and the sun gear 2-1 and planetary gear 2-2 is connected by meshing transmission, and the sun
It is symmetrically provided with slot 3 on end face wheel 2-1 opposite with planet carrier 2-3, ball 4 is provided between the slot 3, described two is symmetrical
The groove depth summation of slot 3 is less than the diameter of ball 4, avoids to reach ball 4 in the case where not influencing sun gear 2-1 rotation
Sun gear 2-1 is contacted with planet carrier 2-3 and is caused to wear.
Embodiment 2
As shown in Fig. 2, a kind of antifriction structure of planetary reducer, including motor input shaft 1 and motor input shaft
The planetary gear set 2 of 1 transmission connection, the planetary gear set 2 include sun gear 2-1, planetary gear 2-2 and planet carrier 2-3, the row
Star-wheel 2-2 is rotatably arranged on planet carrier 2-3, and the sun gear 2-1 and planetary gear 2-2 is connected by meshing transmission, and the sun
It is symmetrically provided with slot 3 on end face wheel 2-1 opposite with planet carrier 2-2, ball 4 is provided between the slot 3, described two is symmetrical
The groove depth summation of slot 3 is less than the diameter of ball 4, avoids to reach ball 4 in the case where not influencing sun gear 2-1 rotation
Sun gear 2-1 is contacted with planet carrier 2-3 and is caused to wear, meanwhile, in the both ends of the surface planetary gear 2-2 opposite with planet carrier 2-3
It is provided with symmetrical auxiliary slot 5, this symmetrically assists being equipped with auxiliary ball 6 between slot 5, in order to make that ball 6 is assisted to separate planet
2-2 and planet carrier 2-3 is taken turns, avoids planetary gear 2-2 from contacting with planet carrier 2-3 and causes to wear, described two symmetrical auxiliary slots 5
Groove depth summation is less than the diameter of auxiliary ball 6.
The utility model reaches guarantee using opening up slot between sun gear and planet carrier and putting the structure of ball
Planetary gear set operate normally rotation under the premise of avoid because accuracy of manufacture problem influence working efficiency and caused by wear, this reality
It is reasonable with new design, it accords with the demands of the market, is suitble to promote.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
