The all other embodiment obtained, belong to the scope of the utility model protection.
It is a kind of tool of the embodiment 1 of the dynamic balance running device of planet carrier class part 4 disclosed in the utility model such as Fig. 1
Body structural representation, the present apparatus include mandrel 1, ring flange 2 and rate taper nut 3, wherein：
Ring flange 2 is fixedly connected on mandrel 1, and the end face of ring flange 2 is vertical with the axis of mandrel 1, and ring flange 2 and mandrel 1 are same
Axle.
Rate taper nut 3 is connected through a screw thread with mandrel 1, and the end face of rate taper nut 3 is vertical with the axis of mandrel 1, rate taper nut 3 with
Mandrel 1 is coaxial, and with mandrel 1 relative motion can occur for rate taper nut 3 in the axial direction, and the periphery of rate taper nut 3 is drift angle direction
Towards the conical surface of ring flange 2, the maximum outside diameter of rate taper nut 3 is more than the inner spline gear outside diameter circle of planet carrier class part 4, taper spiral shell
Mother 3 uses less taper, and can increase the inner spline gear tip circle of planet carrier class part 4 has the contact area of the conical surface, fixes part
Obtain more firm.To ensure the coaxial requirement of rate taper nut 3 and mandrel 1, positioning precision, the conical surface and core of rate taper nut 3 are improved
Axle 1 is Combined machining.
The distance of first end face of mandrel and the second end face of mandrel be more than first flange side surface and the second end face of mandrel away from
From the first end face of mandrel is the end face of the side of 1 mounting flange of mandrel 2, and the second end face of mandrel is that mandrel 1 connects conic nut one
The end face of side, first flange side surface are end face in small distance with the first end face of mandrel on ring flange.
The distance of second end face of mandrel and the first end face of mandrel is more than the first rate taper nut end face and the first end face of mandrel
Distance, the first rate taper nut end face are end face in small distance with the second end face of mandrel on rate taper nut 3.
In summary, a kind of dynamic balance running device of planet carrier class part 4 is present embodiments provided, to planet carrier class zero
When part 4 carries out dynamic balance running, planet carrier class part 4 rotates rate taper nut 3, made between ring flange 2 and rate taper nut 3
Rate taper nut 3 moves relative to mandrel 1 to ring flange 2, because the maximum outside diameter of rate taper nut 3 is more than flower in planet carrier class part 4
Key teeth outside diameter circle, final rate taper nut 3 are tightly fitted on ring flange 2.Because rate taper nut 3 and mandrel 1 are coaxial, and ring flange
2 end faces have that the axis of mandrel 1 is vertical, so planet carrier class part 4 is also coaxial with mandrel 1, mandrel 1 can be arranged on testing stand,

More than first flange dish external diameter, the first rate taper nut external diameter is the maximum outside diameter of the conical surface of rate taper nut 3, and first flange dish external diameter is
The external diameter on the 2 less face of cylinder of ring flange.First flange dish external diameter is that the less gap in gap coordinates with inner spline gear tip circle, such as
H8/h8.It is easy when carrying out dynamic balance running because rate taper nut 3 and the contact area of the internal splines of planet carrier class part 4 are smaller
Circular runout is produced, the ring flange 2 of boss structure can be such that the boss structure of ring flange 2 inserts in planet carrier class part 4, because coordinating
Gap is small, thus when can reduce experiment part circular runout.
There are several mounting holes for further optimization this programme, the end face of rate taper nut 3, mounting hole can be through hole or blind hole,
If mounting hole is blind hole, blind hole is on the end face of the first rate taper nut 3.Rod-like piece can be inserted in mounting hole, be easy to rotate
Rate taper nut 3.Mounting hole can use screwed hole, in screwed rod-like piece advances through hole, will can make in rotation rate taper nut 3
When, rod-like piece does not skid off from hole.
It is welded on for further optimization this programme, ring flange 2 on mandrel 1.Ring flange 2 is fixed on by the way of welding
On mandrel 1, compared with other connected modes, it can eliminate and be shaken caused by gap.And use a process processing method after welding
Blue disk 2 and mandrel 1 it is cylindrical, can both reduce the cylindrical bounce of seam, and ensure that hanging down for the end face of ring flange 2 and the axis of mandrel 1
Straight degree.
Further to optimize this programme, it is more than the step cutting pattern of both sides, and step at the welding flange 2 of mandrel 1 for external diameter
Width is equal to the both ends of the surface distance of ring flange 2.Step cutting pattern is the welding position of ring flange 2, the positioning being easy in welding process.
And deformation of the mandrel 1 because of welding generation can also be reduced using this structure.
In summary, the dynamic balance running device of planet carrier class part 4 that the present embodiment provides has the following advantages：(1) pass through
Planet carrier class part 4 is fixed on 1 enterprising action balance of mandrel and tested by rate taper nut 3 and ring flange 2, and it is flower to realize to inside
Key and both ends carry out dynamic balance running without seam or the planet carrier class part 4 of support.(2) rate taper nut 3 uses less taper,
Increasing the inner spline gear tip circle of planet carrier class part 4 has the contact area of the conical surface, part is fixed more firm.(3) taper spiral shell
The conical surface of mother 3 and the Combined machining of mandrel 1, ensure that the coaxial requirement of rate taper nut 3 and mandrel 1, improve positioning precision.(4)
The ring flange 2 of boss structure can be such that the boss structure of ring flange 2 inserts in planet carrier class part 4, because fit clearance is small, so can
The circular runout of part when reducing experiment.(5) mounting hole uses screwed hole, can by screwed rod-like piece advances through hole
When being easy to rotate rate taper nut 3, and rotating rate taper nut 3, rod-like piece does not skid off from hole.(6) will by the way of welding
Ring flange 2 is fixed on mandrel 1, compared with other connected modes, can be eliminated and be shaken caused by gap.And one is used after welding
Individual process processing ring flange 2 and mandrel 1 it is cylindrical, can both reduce the cylindrical bounce of seam, and ensure that the end face of ring flange 2 and core
The perpendicularity of the axis of axle 1.(7) multi-diameter shaft is used, is easy to the positioning of welding, and reduces the thermal deformation of mandrel 1 in welding process.
