Accompanying drawing explanation
To the utility model, be described in more detail based on embodiment and with reference to accompanying drawing hereinafter.Wherein:
Fig. 1 has shown according to the structural representation of the load bearing mechanism for planetary gear train of the present utility model.
In the accompanying drawings, identical parts are used identical reference character.Accompanying drawing is not according to actual scale.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 has shown according to the load bearing mechanism 50 for planetary gear train of the present utility model.This load bearing mechanism 50 comprises the first load-bearing member 5, and the second load-bearing member 4 that be connected with the first load-bearing member 5 compartments and can resiliently deformable.The second load-bearing member 4 should be elected rigid metallic material as and make, and it can be preferably high-strength metal material, makes it have the ability of good rigidity and good resiliently deformable.In order to facilitate the assembling of sun gear 1, at the circle centre position of the second load-bearing member 4, can be provided with the circular hole 15 of the periphery that is greater than sun gear 1.
According to the utility model, the intermeshing sun gear 1 of planetary gear train and planet wheel 2 are arranged between the first load-bearing member 5 and the second load-bearing member 4.Planet wheel 2 is connected between the first load-bearing member 5 and the second load-bearing member 4 by hollow bearing pin 12.In order to guarantee that sun gear 1 and planet wheel 2 have good engagement effect, planet wheel 2 can be arranged on hollow bearing pin 12 by selfaligning bearing 3.Hollow bearing pin 12 comprises that integrated type radially forms the location shaft shoulder 9 thereon.In the periphery of hollow bearing pin 12, be socketed with adjusting sleeve 14.Adjusting sleeve 14 can be adjusted the axial position on selfaligning bearing 3 hollow bearing pin 12 of living in.Wherein, selfaligning bearing 3, between the location shaft shoulder 9 and adjusting sleeve 14, can be securely fixed on hollow bearing pin 12 like this.In one end of hollow bearing pin 12, can be provided with for it being fixed on to the locating piece 10 on the first load-bearing member 5, and the other end can be provided with for it being fixed on to the locating piece 13 on the second load-bearing member 4.
In practical set process, the engagement place of sun gear 1 and planet wheel 2 there will be very large assembly error conventionally.This assembly error can be produced by machining error, quality of materials and the operating characteristic of sun gear 1 and/or planet wheel 2 conventionally, and the distribution of force of hollow bearing pin 12 that has made to carry planet wheel 2 is extremely inhomogeneous.In order to guarantee that sun gear 1 and planet wheel 2 have good engagement effect, the material of hollow bearing pin 12 is preferably rigid metallic material.
Yet, because hollow bearing pin 12 has good diastrophic ability, so its assembly error can compensate by the bending deflection of self 2 engagement of sun gear 1 and planet wheel time.In order to strengthen further the diastrophic ability of hollow bearing pin 12, locating piece 10 and locating piece 13 are all preferably the bolt with hollow inner chamber.
In the foregoing description, the planet wheel 2 of only take is described in detail the load bearing mechanism 50 for planetary gear train of the present utility model as example, but does not mean that it cannot install a plurality of planet wheels 2.That is to say, when this load bearing mechanism 50 is provided with a plurality of planet wheel 2, assembly error when it also can compensate sun gear 1 with a plurality of planet wheel 2 engagement whole or in part.
In this embodiment, this load bearing mechanism 50 also can comprise for supporting the location unit 11 of the first load-bearing member 5 and the second load-bearing member 4.Location unit 11 comprises the stop collar 7 being located between the first load-bearing member 5 and the second load-bearing member 4, and through being fixed on the fixed block 8 on stop collar 7 after the first load-bearing member 5 or the second load-bearing member 4.The two ends of stop collar 7 are configured with internal thread, and fixed block 8 elect as can with the bolt of its screw-internal thread fit.So just stop collar 7 can be securely fixed between the first load-bearing member 5 and the second load-bearing member 4.
According to the utility model, when sun gear 1 and the engagement of planet wheel 2 occur after assembly error, the assembly error in the time of first can partly or entirely compensating by the bending deflection of hollow bearing pin 12 sun gear 1 and planet wheel 2 engagement.Secondly, the second load-bearing member 4 can allow by the resiliently deformable of self hollow bearing pin 12 that suitable moving radially occurs, thus the assembly error while compensating further sun gear 1 and planet wheel 2 engagement.
Easily understand, according to the utility model, for the load bearing mechanism 50 of planetary gear train, also can effectively compensate planet wheel 2 and internal gear 6(claims again gear ring) assembly error during engagement, its principle and above-described principle are basic identical.For the purpose of saving length, at this, omit.
According to the load bearing mechanism 50 for planetary gear train of the present utility model, the excessive situation of assembly error that it can avoid machining error, quality of materials and operating characteristic because of planet wheel 2 and/or sun gear 1 to cause effectively, thereby balanced sun gear 1 and the suffered load of planet wheel 2, guarantee the use safety of this planetary gear train and load bearing mechanism 50.In addition, simple in structure, easy to process according to the load bearing mechanism 50 for planetary gear train of the present utility model, assembling easily, is used safety, thereby is convenient to practice and extension application.
Although the utility model is described with reference to preferred embodiment, in the situation that not departing from scope of the present utility model, can carries out various improvement and can replace parts wherein with equivalent it.Especially, only otherwise have structural hazard, every technical characteristics of mentioning in each embodiment all can combine in any way.The utility model is not limited to disclosed specific embodiment in literary composition, but comprises all technological schemes in the scope that falls into claim.
