Description
Technical field
The present invention relates to a kind of weaving loom press-roller device.
Background technology
Such pressure roller is for example as known in DE19781721C1.This pressure roller is arranged to be applied especially to texturing machine simultaneously
And there is outer cover, outer cover in the case that centre is connected to intermediate sleeve is arranged on stop sleeve.The stop sleeve passes through depth
Ditch ball bearing rotatably supports with respect to bearing pins (carrying axle is named as in DE19781721C).Pass through pendulous device, zanjon
Ball bearing is with respect to bearing pins can be supported in a manner of its longitudinal axis.
The content of the invention
The pressure roller has deep groove ball bearing, and the deep groove ball bearing is around the inclination vertical with the deep groove ball bearing rotation axis
Axis can be pivotally supported.A part of bearing pins of pressure roller are equally shown as orthogonally to arrange with tilt axis, wherein, deep-groove ball
Bearing can be pivotally coupled by swinging sleeve and bearing pins.Tilt axis are by being arranged in the pendulum of deep groove ball bearing inner radial
The direct collective effects of moving sleeve and bearing pins is realized.Thus, it is not necessary to which being additional to can be by whole deep-groove ball axle thereon
Bear to limit obliquely be hinged bearing pins and be additional to swing sleeve, single part is used for structural dip axis.
Stop sleeve includes two sleeve half, and the two sleeve half are respectively with a shell surface section and one with being somebody's turn to do
The tenon that shell surface section firmly connects, the tenon are embedded into the hole in bearing pins.The two form the sleeve half of stop sleeve not
It must be connected with each other.It is preferred that gap can be formed with particularly simple structural scheme between sleeve half.The gap is necessary
When in a Normal plane on tilt axis.Advantageously, two sleeve half are molded in the same manner.
Sleeve half can be manufactured economically with synthetic material injection moulding, wherein, tenon is integrally molded in respective set
It is in cylinder half and preferably hollow.Alternately, sleeve half can be also fabricated to metalwork, or at the same time using not
Manufactured in the case of particularly being applied with material with bicomponent injection molding method.
Be advantageously improved mode according to one kind, each sleeve half on the inside of it on there is one and bearing pins collective effect
Guide surface, for prevent carry sleeve around the axis vertical with tilt axis and bearing pins inclination.
According to another advantageous embodiment, each sleeve half has two and the coefficient limitation face of bearing pins,
For limiting inclination of the carrying sleeve around tilt axis, and then limit inclination of the whole deep groove ball bearing around tilt axis.
Carrying sleeve is preferably constructed with being substantially in the structural scheme of tank shape, wherein, each sleeve half has one
The bottom section being connected on shell surface section.Between bottom section and shell surface section advantageously on the outside of the sleeve half on construct
Fluted, the groove is provided for being embedded in locating snap ring, and the locating snap ring makes carrying sleeve exist relative to the inner ring of deep groove ball bearing
Fixed on axial direction.
Brief description of the drawings
Below, embodiments of the invention are explained in detail by diagram.The diagram with partial simplified is shown in which, its
In：
Fig. 1 illustrates pressure roller with the first section.
Fig. 2 is shown according to Fig. 1 pressure roller with another profile.
Embodiment
The overall pressure roller indicated with reference 1, the prior art being previously mentioned when in terms of its basic function with reference to beginning,
The pressure roller has bearing pins 2, and rolling bearing, i.e. deep groove ball bearing 3 are tiltably supported by the bearing pins.By synthetic material
Or the outer cover 4 that rubber is formed surrounds deep groove ball bearing 3, this is outer to cover in weaving loom, is especially pressed onto line not in texturing machine
On the outlet roller shown.
Outer cover 4 surrounds intermediate sleeve 5, and the intermediate sleeve surrounds again is configured to the sleeve 6 without cutting remodeling plate,
The outer shroud 7 of deep groove ball bearing 3 is maintained in the sleeve.The inner ring 8 of the subordinate of deep groove ball bearing 3, which accommodates, swings sleeve 9, the swing
Sleeve shows as being connected to the connecting element of bearing pins 2 in the case of the angular mobility required for maintaining.Tilt axis are with K
To mark, deep groove ball bearing 3 can tilt around the tilt axis relative to bearing pins 2.The rotation axis of deep groove ball bearing 3 is come with R
Mark, and rotation axis surrounds a right angle with tilt axis K under any state of pressure roller 1.In depth as shown in Figure 1
In the case of ditch ball bearing 3 is not inclined, rotation axis R overlaps with the longitudinal axis of bearing pins 2.
Swing sleeve 9 to be made up of two identical sleeve half 10,11, the two sleeve half respectively have one and are resisted against
The bottom section 13 of shell surface section 12 and a semicircular in shape on the inwall of inner ring 8.From bottom section 13 to shell surface section
On 12 changeover portion, groove 14 circumferentially is configured with the outside of sleeve half 10,11, it is embedded in the groove to support
Lean against the locating snap ring 15 in inner ring 8.On side of the sleeve half 10,11 away from bottom section 13, the side has flange section 16,
The flange section is equally resisted against in inner ring 8, so show as swing between sleeve 9 and deep groove ball bearing 3 in axial direction
Locating snap ring on (being based on rotation axis R) direction.
By stretching out solid tenon 17 in the embodiment shown, the tenon in the shell surface section on the inner side of shell surface section 12
Arrange with being concentric with tilt axis K, and stretch into the hole 18 in bearing pins 2.In embodiment, hole 18 is configured to through hole,
Two tenons 17 of the through hole receiving sleeve half 10,11.Also can unlike this for each tenon 17 set one individually,
The hole 18 of blind hole is configured in bearing pins 2.Have proven in terms of manufacture and assembling particularly advantageously, as known to Fig. 2,
In the pressure roller 1 completely assembled, bigger gap is formed compared between shell surface section 12 between tenon 17.Two sleeve half
10th, 11 it is coupled to each other not over the bindiny mechanism being molded in both parts.
Directly it is not only in that realization around the limited of tilt axis K with coefficient the swinging sleeve 9 of the task of bearing pins 2
Move pivotally, and also reside in while minimize other unexpected banking motions of deep groove ball bearing 3.For this purpose, set
Cylinder half 10,11 has a guide surface 19, and the guide surface is connected on tenon 17 on the inner side of shell surface section 12 and along bearing pins 2
Extension.Pivoting action of the deep groove ball bearing 3 around tilt axis K is limited by limitation face 20, these limitation surface constructions exist
On the inner side of flange section 16 and can knocking in bearing pins 2.It is additional or alternately, it can be held by being placed in
The diskware 21 carried on pin 2 is limited pivoting action of the deep groove ball bearing 3 around tilt axis K, and the diskware shows as depth simultaneously
Cover plate on that side stretched out in bearing pins 2 are by sleeve 6 of ditch ball bearing 3.Put on the contrary in the phase of deep groove ball bearing 3
On side, bearing pins are covered by the diskware section 22 rotated together with sleeve 6.
