Said compensating disc is provided with curve bath 1202, and the degree of depth of said curve bath 1202 is gradual changes.Said gear 110 is provided with blind hole, and promptly compression spring hole 1102.Being provided with compression elastic piece in the said compression spring hole 1102 is stage clip 114.And accommodate sliding pin 116 in the said curve bath.One end of said sliding pin 116 is positioned at the bottom of said curve bath 1202, and the other end stretches into said compression spring hole 1102 and is pressed on the said stage clip 114.
Particularly, as shown in Figure 1, first running shaft 106 circumferentially is fixedly connected through flat key 118 with gear 110.Therefore, the power of first running shaft 106 and moment of torsion can be passed to gear 110.In addition, gear 110 and another gear (not shown) engagement are so that pass to this another gear with the power and the moment of torsion of first running shaft 106.Yet, if axial dipole field takes place gear 110, can have a strong impact on gear 110 and said another gear meshing, be unfavorable for the accurate transmission of power and moment of torsion.Causing gear 110 that the reason of axial dipole field takes place, for example is the expansion that first running shaft 106 rises because of temperature.Below will specify the structure of this nose balance device, and the working principle of the axial dipole field distance of this this gear 110 of nose balance device compensation.
At first combine Fig. 1 to introduce the constituent element of this nose balance device.This nose balance device comprises gear 110, hollow shaft 112, stage clip 114, sliding pin 116, compensating disc 120, packing ring 122, elastic washer 124 and bolt 126.Gear 110 is one with hollow shaft 112.Compensating disc 120 is set on the said hollow shaft 112.Gear 110 is circumferentially fixing through flat key 118 and keyway 108 with said first running shaft 106, but can take place axially to relatively move between gear 110 and said first running shaft 106.The part of flat key 108 sides of said first running shaft 106 is passed said gear 110, and is plugged in the said hollow shaft 112.The end of said first running shaft 106 has tapped hole.
As stated, compensating disc 120 is set on the said hollow shaft 112; Said first running shaft 106 plug with said hollow shaft 112 in, and the end of said first running shaft 106 has tapped hole.Wherein, the end of said first running shaft 106 also is fastened with packing ring 122.Said packing ring 122 is fixed on the end of said first running shaft 106 through the bolt 126 and the screw-thread fit of tapped hole.Wherein, the effect of elastic washer 124 is to improve fastening performance.Certainly, also elastic washer 124 can be set.Like this, on the axial direction of first running shaft 106, a side of compensating disc 120 is limited on packing ring 122, and opposite side is limited gear 110.
Like Figure 10 and shown in Figure 11, on said gear 110, be provided with two compression spring holes 1102.Be placed with a stage clip 114 that is in compressive state in two compression spring holes 1102 respectively.
In addition, to shown in Figure 12, in the relative side of compensating disc 120 and gear 110, compensating disc 120 is provided with two curve baths 1202 like Figure 10.The position and the shape of this curve bath 1202 are shown in figure 11.These two curve baths 1202 are about the center symmetric arrangement of compensating disc 120.And the center of the circular arc at the sidewall place of this curve bath 1202 overlaps with the center of compensating disc 120.The width of these two curve baths 1202 is constant, is a bit larger tham the diameter of sliding pin 116.Should find out that the degree of depth of these two curve baths 1202 is gradual changes, and is shown in figure 12, Figure 12 is the unfolded drawing of C-C along the line among Figure 11.In the present embodiment, these two curve baths 1202 are maximum in the local degree of depth relative with compression spring hole 1102, and more than half part of sliding pin 116 is positioned at this curve bath 1202, and remaining part is positioned at said compression spring hole 1102.At this moment, sliding pin 116 application of forces, compression press spring 114.Therefore, there is the active force that compresses each other between packing ring 122, compensating disc 120, the gear 110.
Shown in figure 10, when first running shaft 106 for example Yin Wendu raise and when expanding, have more certain clearance between said gear 110 and the said compensating disc 120.At this moment, said stage clip 114 can apply active force to sliding pin 116, makes sliding pin 116 in said curve bath 1202, slide towards the less place of the degree of depth, and compensating disc 120 rotates a certain angle and the axial dipole field certain distance simultaneously, and gear 110 positions are motionless.Thus, can prevent the axial dipole field of gear 110, make that the engagement of gear 110 can be more accurately with reliable.
Because having the profile track of the gradual change of 1/4th symmetrical arcs on the compensating disc 120 is curve bath 1202; So when axial dipole field takes place in gear 110; Slide along arc track under the pressure effect of the stage clip 114 of sliding pin 116 meetings in the compression spring hole of being located at gear 110 1102, and gear 110 stroke in the axial direction can carry out the axial distance compensation according to the stroke of said sliding pin 116 on curve bath 1202.That is to say that the degree of depth that can be through setting curve bath 1202 and gradual change form compensate the skew of gear 110 on axially, make that the position maintenance of gear 110 is motionless.Though in the specific embodiment of the present invention; These two curve baths 1202 are maximum in the local degree of depth relative with compression spring hole 1102; But the shallow form in dark both sides in the middle of also can the degree of depth of curve bath 1202 being arranged to, that is: it is set as the case may be, does not receive the restriction of this specific embodiment.
When assembling, earlier gear 110 is installed on first running shaft 106, then stage clip 114 is put in the compression spring hole 1102 of said gear 110,, can select the suitable stage clip of stiffness coefficient here according to the size of driving force; The compensating disc 120 that will be inserted with sliding pin 116 afterwards packs into the hollow shaft 112 on the gear 110, and stage clip 114 is alignd with sliding pin 116; Then, flat key 118 is installed, and packing ring 112, elastic washer 124 and bolt 126 are installed, thereby fixingly guarantee that first running shaft 106, compensating disc 120, gear 110 are the integral body of axial constraint.
Wherein, circumferentially fixing between the gear 110 and first running shaft 106 with two circumferentially symmetrical flat keys 118, thus can carry out transmission.In addition, the end face of said compensating disc 120 carries out axial constraint with bolt 126, elastic washer 124, packing ring 122.And the axial distance compensation can also prevent that gear 110 is in circumferential counter-rotating.Its reason is that axial play can make sliding pin 116 slide along rotating locus, and the straight line displacement distance that axial float caused is bigger than the distance that moves along helix, and spiral trajectory is gradual change.
Those skilled in the art know easily; The above is merely preferred embodiment of the present invention; Not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.Protection scope of the present invention is confirmed by claims.
