Abstract
The utility model provides a central torque transmission detachable type planet carrier structure. The central torque transmission detachable type planet carrier structure comprises a transmission shaft and a planet carrier body coupled with the transmission shaft, wherein the planet carrier body is provided with a coupling plate, a left side plate and a right side plate; the left side plate and the right side plate are provided with planet wheel bearing mounting holes; the transmission shaft is provided with a positioning plate; the coupling plate on the planet carrier body is coupled with the positioning plate on the transmission shaft by a torque transmission pin; and a gap is formed between the left side plate at one end of the planet carrier body and the transmission shaft and a gap is formed between the right side plate at the other end of the planet carrier body and the transmission shaft. According to the central torque transmission detachable type planet carrier structure, a torque is transmitted in the coupling plate, so that relative deformation between the side plates at the two ends can be reduced effectively and the axis of a planet wheel is wholly deviated; and therefore, the uniform distribution of the load of the planet wheel is guaranteed and the uniform load performance of the transmission of a planet gear is improved effectively. Meanwhile, the central torque transmission detachable type planet carrier structure has good rigidity and strength and the uniformity of the load of the planet wheel in a tooth width direction can be guaranteed.
Description
Technical field
The utility model relates to a kind of planetary transmission part, is specifically related to a kind of center torsion pass detachable planet carrier structure.
Background technique
Planetary Gear Transmission is lightweight owing to having, bearing capacity reaches by force the efficiency advantages of higher, is widely used in each industrial field.Planet carrier is one of critical component of Planetary Gear Transmission, it is also the part that bears the moment of face maximum, and its distortion is very large on the impact of gear engagement stress distribution, therefore, planet carrier structure must have enough strength and stiffness, will guarantee the stationarity of torsion pass simultaneously.Mostly apply end torsion pass type planet carrier in prior art, end torsion pass type planet carrier is exactly that moment of torsion reaches the planet carrier of opposite side by the distolateral plate of planet carrier one, end torsion pass type planet carrier is an end torsion pass structure, relative deformation between this structure planet carrier biside plate is larger, cause the axis of planet wheel to produce deflection, totally unfavorable to the uniform distribution of the suffered load of planet wheel.
The model utility content
In order to solve above-described problem, the utility model provides a kind of center torsion pass detachable planet carrier structure, the utility model can reduce the relative deformation between planet carrier body two end side panels effectively, guarantees planet wheel stand under load being uniformly distributed along facewidth direction.
The utility model adopted technological scheme of dealing with problems is: a kind of center torsion pass detachable planet carrier structure, comprise transmission shaft and with the planet carrier body of described propeller shaft couplings, it is characterized in that: described planet carrier body is provided with joining plate and left sideboard and right sideboard, be equipped with the planet wheel bearing mounting hole on described left sideboard and right sideboard, described transmission shaft is provided with positioning plate, and the joining plate on described planet carrier body connects by the torsion pass pin with the positioning plate on described transmission shaft; Be provided with gap between the left sideboard at described planet carrier body two ends and right sideboard and described transmission shaft.
Preferably, between the joining plate of the body of planet carrier described in the utility model and the positioning plate of described transmission shaft, form fitting surface, described fitting surface is locating face, for radial location.
Preferably, described in the utility model, joining plate is provided with plug screw, and described plug screw compresses described torsion pass pin.
Preferably, the left sideboard at the body of planet carrier described in the utility model two ends and right sideboard are identical with the axial distance between the torsion pass pin.
The beneficial effects of the utility model are: the utility model due to moment of torsion in the joining plate intermediate transfer, can effectively reduce the relative deformation between two end side panels, make the axis generation overall offset of planet wheel, thereby guarantee the uniform distribution of planet wheel load, that effectively improves Planetary Gear Transmission all carries performance.The utlity model has good Rigidity and strength simultaneously, can guarantee the uniformity of planet wheel stand under load along facewidth direction.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 on the A-A direction.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of center torsion pass detachable planet carrier structure, comprise transmission shaft 1 and the planet carrier body 2 connected with described transmission shaft 1, described planet carrier body 2 is provided with joining plate 5 and left sideboard 8 and right sideboard 10, be equipped with planet wheel bearing mounting hole 7 on described left sideboard 8 and right sideboard 10, described transmission shaft 1 is provided with positioning plate 11, and the joining plate 5 on described planet carrier body 2 connects by torsion pass pin 4 with the positioning plate 11 on described transmission shaft 1; Be provided with gap 9 between the left sideboard 8 at described planet carrier body 2 two ends and right sideboard 10 and described transmission shaft 1.
As a kind of preferred version of the present utility model, form fitting surface 6 between the joining plate 5 of described planet carrier body 2 and the positioning plate 11 of described transmission shaft 1, described fitting surface 6 is locating face, for radial location.
As a kind of preferred version of the present utility model, described joining plate 5 is provided with plug screw 3, and described plug screw 3 compresses described torsion pass pin 4.
As a kind of preferred version of the present utility model, left sideboard 8 and the right sideboard 10 at described planet carrier body 2 two ends are identical with the axial distance between torsion pass pin 4.
The joining plate 5 of the utility model planet carrier body 2 connects by torsion pass pin 4 with the positioning plate 11 of transmission shaft 1, fitting surface 6 is locating face, and for radial location, torsion pass pin 4 is for circumferential registration and transmitting torque, plug screw 3 is tightened and is locking, for preventing torsion pass pin 4 plaies.There is gap 9 between the left sideboard 8 at planet carrier body 2 two ends and right sideboard 10 and transmission shaft 1, moment of torsion transmits between left sideboard 8, right sideboard 10 and the planet wheel bearing at planet carrier body 2 two ends by planet wheel bearing mounting hole 7, pass to transmission shaft 1 by torsion pass pin 4 again, because the side plate at planet carrier body 2 two ends is identical with the axial distance between torsion pass pin 4, the rigidity of the side plate at planet carrier body 2 two ends and stressed basic identical, so the distortion of planet carrier body 2 two end side panels is basic identical, can guarantee that the planet wheel stand under load is uniformly distributed along facewidth direction.
