Or assembly inaccuracy causes excessive interference fit, or the caused wide arc gap of crossing of abrasion is made to be compensated；Therefore processing can be reduced
The requirement of precision reduces abrasion, it will be apparent that extends the service life of the needle tooth cycloidal reducer 100, keeps precision.
Specifically, please refer to shown in Fig. 4 ~ Fig. 8, the transmission roller 7 include by steel band 712 or steel wire 712' spirals it is close around
The hollow rollers 71 of formation, " close around " refer to steel band 712 or the seamless spiral windings of steel wire 712', on 71 edge of the hollow rollers
When its both ends being axially distributed is squeezed, the length of the hollow rollers 71 is constant.Wherein, Fig. 4 only illustrates the transmission
The one circle steel band 712 or steel wire 712' of the axial one end of roller 7.
The hollow rollers 71 are when by ambient pressure, end not cracky, and in use will not be in
Portion's infiltration and development, service life are long.Analytic explanation is as follows：
It please join shown in Fig. 3, be axially that the hollow rollers of an entirety can be understood as the longer hollow rollers of length along it, below
Referred to as long hollow rollers；When there is pressure P to act on long hollow rollers end, end can deform.Specifically, end
Tube wall can be recessed inwardly under the action of pressure P, and such as CDE is surrounded in figure a pit is formed around.This pit exists
It is most deep at port, and it is most shallow at farthest D at port.It is formed in Fig. 1 with the curve represented by dotted line after the indent of port.
At inner wall A points are moved on to after original B points indent.The distance that 2 points of AB is on Fig. 3 represented by △, i.e. maximum deformation distance herein.
In the present invention in steel band 712 or the close hollow rollers 71 around formation of steel wire 712' spirals, with the hollow rollers 71
The one circle steel band 712 or steel wire 712' of axial one end constitute short hollow rollers shown in Fig. 4, when pressure P' act on in Fig. 3
Long hollow rollers when there are the short hollow rollers of same diameter and thickness, short hollow rollers are similarly formed indent phenomenon, Fig. 4's
Dotted line indicates deformation in this case.Under pressure P' appropriate effects, original B' points move on to recessed △ ' at A' at inner wall.
At this moment, it has been found that even if △ '=△, i.e. the amount of the two indent is identical, but deformation distance is different, and the property of deformation has been
It is complete different.
For long hollow rollers shown in Fig. 3, due to being constrained by overall length rigidity, it is attached that deformation can only occur in port
In nearly loop CDE one piece small；Tube wall change in shape is fierce at A points, radius of curvature very little.And for shown in Fig. 4 short hollow
For roller, since length direction does not have much constraints, so the both ends of short hollow rollers in an axial direction represented by the dotted line of Fig. 4
Deformation curve at mouthful is almost parallel identical.Circumferentially one section of camber line very long from C' to E' has been involved in deformation, therefore
Although the sinkage △ ' of inner wall B' points is equal with the △ in Fig. 3, the change in shape of tube wall is little at the point, radius of curvature
It is very big；The variation of radius of curvature indicates the degree of true strain at this.Therefore, even if the two sinkage is identical, but long hollow rolling
Column is possible to crack, but short hollow rollers are safe, and non-breakable, service life is long.
By upper analysis it is found that short hollow rollers can bear larger deformation than long hollow rollers, therefore, of the invention is described

Diameter is 1.5mm；Or the outer diameter of hollow rollers 71, when being 10mm, the thickness of steel band 712 or the line footpath of steel wire 712' are 2.5mm；Or
When the outer diameter of hollow rollers 71 is 1.5mm, the thickness of steel band 712 or the line footpath of steel wire 712' are 0.3mm.
When the outer diameter of the hollow rollers 71 is larger, the tube wall of the hollow rollers 71 is also thicker, can make described
Hollow rollers 71 inherently have certain impact strength, while when by larger external force extruding, and can generate certain
Flexible deformation compensate.The tube wall of the hollow rollers 71 and the consistency of thickness of steel band 712 or steel wire 712' it is compact it is close around
