It is circular medium pore 322 that separator 32 is provided with overall, and medium pore 322 centers in axis X 32, and being in of the sub-component 30 on axle 10 is installed in configuration, and axis 32 and axis X 10 merge.Separator 32 comprises annulus 323, forms porose 322 in the central authorities of annulus 323, and hole 322 extension 324 that is equipped with the spine 325 of sclerosis be less than 90 ° apex angle α limited angle part on extend.In practice, angle [alpha] is less than 70 °, is preferably about 60 °.

Lug 326 radially extends from the periphery of part 323 towards the outside relative to axis X 32.This lug limits inside shoulder 326A, and the shape of shoulder 326A coordinates with the outstanding shoulder 62A on the edge 62 being arranged on housing 6, and this edge 62A is straight line and the X10 that parallels to the axis.Therefore lug 326 forms the supporting member of separator 32 on edge 62.Consider the fit shapes of shoulder 326A and shoulder 62A, this supporting is sealed.

Separator 32 also comprises the second lug 327, second lug 327 and relatively extends from extension 324 and part 323, and is defined for the first recess 327A holding lip 126.Therefore, lug 327 forms the contact member contacted with the standing part formed by boots portion 124 of dobbies 2.Consider the respective shape of recess 327A and lip 126, this contact is sealed.

324A represents the edge relative with part 323 of extension 324.This edge is circular and centers in axis X 32.In the mounted configuration of the sub-component 30 of machine 2, the inner surface 127 that sub-component 30 is the cylinder portion with round base portion with the form of felt matter layer 125 contacts.Therefore, edge 324A also forms the sealing contact member contacted with the part in boots portion 124.

Separator 32 also comprises the 3rd lug the 328, three lug 328 and extends from the direction of part 323 at the bearing of trend overall vertical with lug 326, and forms the plane surface 64A being used for being formed with the internal-rib 64 by framework 6 and prop up the plane surface 328A leaned on.As lug 326, lug 328 forms the supporting member of the part against housing 6.

Therefore, as shown in Fig. 1 and Fig. 9, sub-component 30 can be arranged on around axle 10, and its lug 326 and lug 328 rest on the corresponding part of framework 6, and its lug 327 contacts with boots portion 124.

In sub-component 30, separator 32 carries axial stop 34 and two rounded seal 36 and 37.These seals can have circular section, such as O shape ring, or have polygonal cross-section.

More accurately, separator 32 is defined for the shell 329 holding axial stop 34.This shell 329 is limited in the thickness of separator 32, on the periphery in hole 322, axially between the tongue 330 and 331 extended along the direction of axis X 32 from the edge in hole 322.Tongue 330 is arranged on the sidepiece 32A of separator 32 in couples, and this is visible in figure 3.Tongue 331 is arranged on the sidepiece 32B of separator 32 in couples, and this is visible in figure 6.In hole 322 circumferentially, a pair tongue 330 is arranged near a pair tongue 331.These offset a segment distance D32: this distance D32 correspond to the width along axis X 32 of shell 329 to tongue 330 and 331 X32 that parallels to the axis.

Shell 329 is also limited by tongue 332, and tongue 332 extends from the edge in hole 322 and on the direction of axis 32, on the sidepiece 32A identical with tongue 330.

In addition, sticking department 333 is formed by a part for separator 32, and sticking department 333 is can by the elastic deformation of hinge 333A that formed by thin region sticking department 333 and part 323 are linked together relative to part 323 movement.Be provided with tongue 334, tongue 334 extends sticking department 333---on sidepiece 32b relative with the sidepiece of carrying tongue 332 of separator 32---on the direction of axis X 32.Tongue 332 and tongue 334 are separated a segment distance D33 along axis X 32, and distance D33 has the value identical with distance D32 and corresponds to the width of the shell 329 near sticking department 333.The surface of tongue 330,331,332 and 334 is defined as the inner surface towards shell 329 of these tongues, that is, these tongues be orientated the sidepiece that is positioned at relative to the tongue surface towards the sidepiece relative with separator 32.Can see in the figure 7, these inner surfaces are pulled away from each other close to during axis X 32 at it.Distance D32 and distance D33 measures in " bottom ", or the external diameter edge of shell 329, namely at the base portion place of tongue.

Sticking department 333 be can be shown in Figure 3 the second place shown in primary importance and Fig. 8 between movement, in primary importance, sticking department 333 does not hinder axial abutting part 34 to arrange in place by the sidepiece 32B of separator 32 visible in Fig. 6 in shell 329 inside, in the second position, sticking department 333 prevents axial stop 34 from shifting out from shell 329.

Sticking department 333 is can by the local deformation at hinge 333A place of separator 32 movement between these two positions.As distortion, this sticking department can be added on separator 32 and also can make mainly radially to move relative to axis X 32.

Therefore, sticking department 333 can close shell 329 when abutting part 34 is placed on wherein, this shell by part 323 radially outward and be limited to tongue 330 on sidepiece 32A and tongue 332 along axis X 32, and tongue 331 on the 32B of the other side and between tongue 334.The outer diameter zone of shell accommodating retaining members 346 and keeper 348, near its edge 346B and 348B, this is enough to be remained on separator 32 by axial abutting part when it does not hold between two driver elements 20.In other words, abutting part 34 remains on separator 32 by the external diameter edge that the size of shell 329 is set to pass shell 329.Therefore shell 329 is the shell for partly holding abutting part 34.

The bottom of shell 329, namely, the exterior circumferential in hole 32 of part 323 relative to axis X 32 extend and between tongue 330 and tongue 332, first extend relative to axis X 32 surface then extended between tongue 331 and tongue 334 and be provided with boots portion 335 of 335, four, four boots portions and be distributed in regularly around axis X 32 and make retainer 34 can by hold and bearing edge 346B and edge 348B center on this axis.

Axial stop 34 comprises several metal roller 342, metal roller 342 is maintained in relative position relative to each other by support 344, and support 344 is that synthetic material is made and is inserted between two keepers 346 and 348 of making through cutting, folding metallic plate.X34 represents the central axial line of abutting part 34.This axis be keeper 346 and keeper 348 by the rolling of roller 342 relative rotation axi line relative to each other.

Support 344 is provided with several bead 344B on its outer peripheral edge edge 344A, several bead 344B are distributed in around axis X 34 regularly and sum is five in this example, its thickness e 1 that the X34 that parallels to the axis measures is greater than the identical axis of the part being parallel to support 344 and the thickness e 2 measured, in thickness e 2, be limited with the shell for holding roller 342, this shell is with by roller 342, the lug 344C remained on support 344 meets boundary.

The quantity of bead 344B can be different from five, keeps equal to or greater than two.Do not consider this quantity, bead is regularly distributed around axis X 34.If the sum of these beads is two, then it is radially relatively arranged relative to this axis.

Bead 344B is arranged to interact with external diameter edge 346B and 348B of keeper 346 and keeper 348, described external diameter edge 346B and 348B is folded into the X34 that parallels to the axis, bead 344B is centered relative to keeper, and this also allows roller 342 to center relative to these keepers.

Up to now, and according to EP-A-0 140 800, the axial abutting part used together with the pull bar of tapping machine comprises the ball bearing guided by the raceway formed by keeper.---being like this when prior art material---as long as the axial load that abutting part bears is relatively little, this allows.But under heavy load, ball bearing has the trend of wearing and tearing or wearing and tearing keeper.Up to now, roller abutting part can not be used, this is because the guiding relative difficulty relative to keeper of roller bearing.The use of support 344 and the use of bead 344B thereof bring this way to solve the problem, and described bead 344B cooperates with keeper 346 and keeper 348, and itself is held in place in shell 329.

Separator 32 also comprises two shells 336 and 337, and shell 336 and shell 337 are radially limited to around shell 329, and respectively on sidepiece 32A and sidepiece 32B, and each is respectively used to hold rounded seal 36 or 37.
