As driven by motor.Flange 7 is preferably connected with drive shaft by big pitch engaging mechanism.Logical
Crossing diameter difference, outer rolling circle 4 has the driving side block being especially perpendicular to rotation axis 2 extension
Shoulder 8.It is more than the outer rolling inside shoulder block 8 towards the diameter of interior rolling ring 3 end face of shoulder block 8
The interior diameter of moving-coil 4, thus the axially-movable of interior rolling ring 3 is kept off in one direction
The restriction of shoulder 8.
In the side relative with shoulder block 8, it is provided with the free end face of the outer rolling circle 4 that reclines and leads
Dish 9 and axially and this godet is the most snugly provided with block plate 10.Godet 9 is the most axial at this
Recline outer rolling circle 4 end face and especially limit jamming roller 5 axial displaceability.
Block plate 10 is preferably made up of two complementary semi-ring semicircular ring in other words, and they collectively form one
Individual toroidal annular block plate 10 in other words.The two semi-ring suitably each extends at this
Through 180 °.Godet 9 and block plate 10 are both constituted in annular, here, and block plate
The interior diameter of 10 is designed to the overall diameter less than interior rolling ring 3, thus avoids godet 9 He
Between rolling ring 3, radial direction contacts with each other.And the interior diameter of block plate 10 is by structure the most smaller
Become so that block plate 10 is joined to diminish in the diameter of interior rolling ring 3 portion's form diametrically
In groove 11.Thus obtain interior rolling ring 3 and axially retained or only stay block plate 10 and gear
Between shoulder 8.Block plate 10 and shoulder block 8 is so constituted: interior rolling ring 3 is retained to the greatest extent at this

Having capping 12, it is joined respectively on block plate 10 and outer rolling circle 4 in the axial direction.
To this end, capping 12 at one end has angled portion 13, this angled portion substantially has
Axial component 14 and the footpath connected with this axial component with an angle (the most about 90 °)
To part 15.Radial component 15 extends to rotation axis 2 and extends internally in other words, therefore exists
It is joined on Zhou Xiang on block plate 10.Axial component 14 transits to cover the sleeve-like parts of 12,
This sleeve-like parts is parallel to capping or the longitudinal extension part of freewheel 1 and extends.
There is at least one but according to this reality at the other end, the substantially capping 12 in sleeve-shaped
Executing example is multiple radial protrusions 16 inwardly, and they are embedded in the outer peripheral face 18 of outer rolling circle 4
On radial groove 17 in, thus, capping 12 is joined on outer rolling circle 4 in the axial direction.
Fig. 2-5 illustrates the embodiment of a favorable structure of freewheel 1, wherein Fig. 2-5
Distinct methods step for manufacturing freewheel 1 is shown.Fig. 5 shows and installs
The freewheel manufactured in other words.Additionally, Fig. 2-5 is respectively with the longitudinal section of Fig. 1
Amplify Local map and show freewheel 1.
This favorable structure specify, angled portion 13 local the most in other words in a region with gear
Dish and the most also with godet 9 axially spaced-apart and spaced radial extend.Thus, not only along footpath
To between block plate 10 and capping 12 and vertically between block plate 10 and capping 12
Coherent space is all provided.
This axial air gap causes the axial force introduced by radial component 15 not at block plate 10
It is passed into block plate at largest outer diameter, but at small diameter, is passed into block plate 10, thus
Even if godet 9 is constituted softly, the orientation of block plate still remains perpendicular to rotation axis 2.
This axial air gap radially extend the embodiment that size is preferably not shown here according to be as
This selects: the axial force introduced by radial component 15 is at the mid diameter quilt of block plate 10
Introduce.Additionally, this axially spaced-apart allows angled portion 13 elastic deformation, this causes capping 12
Long-time axial pretightening.Radial gap is used for making cover plate 10 and godet 9 not loaded by radial force,
And avoid especially at the abutting of a side edge of block plate 10, when this is connected to carry for a long time
Can cause covering impaired.
And, specify according to the expedients in the present embodiment, capping 12 with godet 9
With there is in the axially extending part in block plate 10 compartment of terrain 14 on its outer peripheral face reduce straight
Footpath, here has conical structure.So select tapering at this, make capping 12 axially
Outer peripheral face diameter in part 14 is incremented by towards outer rolling circle 4 from radial component 15.Outside
While the increasing diameter of side face, cover the 12 inner peripheral surface diameter at least bases in the same area
This most constant as a result, along with outer peripheral face diameter be incremented by and the preferably capping 12 in this region
Material thickness is also incremented by.
Fig. 2 shows the first installation steps of the capping 12 of freewheel 1.At initial shape
Under state, radial component 15 at least local also axially towards outer rolling circle 4 direction extend,
Thus, this angled portion has the angle less than 90 °.The other end of capping 12 exists vertically
Extend on outer rolling circle 4, the most so select interior diameter, make capping 12 the most substantially keep flat
On outer peripheral face 18.In an initial condition, sleeve-shaped covers 12 and extends across groove at this
17。
In second step as shown in Figure 3, compacting part 21 is made axially to shift to cover 12
Radial component 15, as by shown in arrow 22.Compacting part 21 makes angled portion 13 at this
Elastic deformation, although thus this axial air gap reduce, but exist.This reality according to Yin
Execute example radial component 15 at the transition position to axial component in the side opposed with outer rolling circle 4
There is axial projection, therefore compacting part 21 has the biggest recessed sky portion herein, to avoid
This radial component presses against block plate 10 completely.
In the next step shown in fig. 4, annular undergauge circle 23 is installed to capping by axially set
On 12, as by shown in arrow 24.Undergauge circle 23 has inclined plane 25, and it causes such
Interior diameter, this interior diameter be designed at least slightly less than to cover 12 corresponding to outer rolling circle
The outer peripheral face overall diameter of the end of 4.Thus, when being pressed to cover 12 by undergauge circle 23
Time upper, so it be pressed against the outer peripheral face 18 of outer rolling circle 4 in the case of being sealed on plastic deformation, and made
The material of capping 12 is squeezed in groove 17.The material being squeezed into constitutes capping 12 at this
Above-mentioned radial protrusion 16, in its axial engagement to outer rolling circle 4.Constitute axially in cone
Portion 14 ensure that at this undergauge circle 23 makes capping 12 not along block plate 10 and godet 9
Deforming in the region radially extended, thus, spaced radial can be reduced or be wholly absent.When
During suit undergauge circle 23, undergauge circle at least contacts the end of conical area, the most also by right
Capping 12 applying axial force.So, when undergauge circle elapses further along arrow 24 direction,
Capping 12 is pulled as a result, produce or increase at horn-like part towards the direction of outer rolling circle 4
Divide the elastic pre-stress in 13.
Clamp-oned by the material under capping 12 plastic deformations, capping 12 rolling ring 4 outside
On axial location be locked.Based on produced angled portion 13 elastic deformation, envelope before
Lid 12 keeps being in axial pretightening state after compacting part 21 and undergauge circle 23 are taken away, borrows
This makes block plate 10 and godet 9 reliably compress outer rolling circle 4 to realize axial grip, such as figure
Shown in 5.
The especially fixing capping of the favourable configurations of freewheel 1 and favourable manufacture method thereof
The method of 12 makes with simple and that the ways and means of low cost ensure that freewheel 1 length
Use the life-span.Especially it is achieved in little gear 6 or the minimum axial gap of interior rolling ring 3, especially
It is that while flexibly to constitute godet 9, thus, freewheel 1 and especially default
The service life of lubricant is extended.
Ensure that in a word in the described region of angled portion 13 capping 12 with block plate 10 it
Between and if desired and be not in contact with, thus between godet 9, it is therefore prevented that stress concentration effect is also
And the incoming diameter portion of the power that avoids, this may cause dish protuberantia.
