All be equipped with the sealing washer between one end that first support body, second support body were kept away from mutually and the dabber. The sealing washer is the rubber circle. The utility model discloses make the false twister spindle can stable rotation, life be longer, improves production efficiency, and it is more convenient to install.
Description
Technical field
The utility model belongs to rolling bearing field, particularly to a kind of scroll tube bearing.
Background technology
The driving and driven ingot axle of original hds-ex2 draw texturing machine scroll tube is to be positioned with bearing outer ring, in the middle of axle
Bearing designation is: 6000zznr, axle end bearing model: 6000zz, and its axially position fully relies on two back-up rings, high for a long time
After speed operating, easily cause axial float, make that on ingot axle, the axial gap spacing between frictional disk is irregular, eventually affect tow
False twisting effect.
In prior art, there is a kind of scroll tube bearing, its structure includes the outer circle rack of axially hollow setting, and outer circle rack passes through
Circumferentially disposed steel ball group is sleeved on mandrel periphery, is provided with the holding for preventing steel ball dislocation between described outer circle rack and mandrel
Frame.Because steel ball is circumferentially disposed, mandrel is produced with the pressure of all directions it is ensured that stablizing of mandrel amplitude, improve
Positioning precision；Retainer plays positioning action to steel ball, prevents steel ball from misplacing, it is disadvantageous in that: the steel ball in outer circle rack
Group can only be supplied to mandrel support force in a plane, and the two ends of mandrel easily produce radially rocks；The internal junction of retainer
Structure is invisible to the naked eye, and it is inconvenient that mandrel installs positioning.
Utility model content
The purpose of this utility model be provide a kind of scroll tube bearing so that spindle axis of false twister can smooth rotation, use
Life-span is longer, improves production efficiency, installs more convenient.
The purpose of this utility model is achieved in that a kind of scroll tube bearing, including the outer circle rack of axially hollow setting,
Outer circle rack is sleeved on mandrel periphery by circumferentially disposed steel ball group, is provided with for preventing steel ball between described outer circle rack and mandrel
The retainer of dislocation, described outer circle rack includes the first support body being symmetrical set and the second support body, the first support body and the second frame
Body phase to one end be respectively equipped with outward flange, described outward flange is provided with flange connecting hole, described first support body and the second support body
Between through being fixedly connected through the securing member of flange connecting hole, be respectively equipped between described first support body, the second support body and mandrel
Least one set steel ball group.
When the utility model is installed, technical staff first mandrel is arranged in first body, then mandrel is extended the
One end correspondence of one support body is arranged in the second support body, then is fixedly connected the first support body and the second support body with securing member.
Compared with prior art, the beneficial effects of the utility model are: by arranging at least two groups steel ball groups, mandrel is played stable
Supporting role, it is to avoid mandrel radial direction is rocked；First support body and the second support body are installed separately, then with securing member by the first support body and
Two support bodys are fixedly linked, and technical staff is convenient when installing, and installation accuracy is higher, it is to avoid mandrel is installed not in place.This bearing
Make spindle axis of false twister stability of rotation, amplitude is little, reliability is high, service life is longer.
As of the present utility model preferably, described securing member is bolt.
In order to prevent dust and other impurities from entering outer circle rack it is ensured that mandrel smooth rotation, described first support body, the second support body are mutual
Away from one end and mandrel between be equipped with sealing ring.
For reduces cost, improve the economic benefit of enterprise, described sealing ring is rubber ring.
Brief description
Fig. 1 is structural representation of the present utility model.
Wherein, 1 outer circle rack, 101 first support bodys, 101a outward flange, 102 second support bodys, 2 steel ball groups, 3 mandrels, 4 holdings
Frame, 5 securing members, 6 sealing rings.
Specific embodiment
As shown in figure 1, being a kind of scroll tube bearing, including the outer circle rack 1 of axially hollow setting, outer circle rack 1 passes through circumference
The steel ball group 2 of setting is sleeved on mandrel 3 periphery, is provided with the retainer 4 for preventing steel ball dislocation between outer circle rack 1 and mandrel 3,
Outer circle rack 1 includes the first support body 101 being symmetrical set and the second support body 102, the first support body 101 and the second support body 102 phase
To one end be respectively equipped with outward flange 101a, outward flange 101a is provided with flange connecting hole, the first support body 101 and the second support body
It is fixedly connected through the securing member 5 through flange connecting hole between 102, securing member 5 is bolt；First support body 101, the second support body
It is respectively equipped with least one set steel ball group 2 between 102 and mandrel 3.First support body 101, the second support body 102 one end away from each other and
It is equipped with sealing ring 6 between mandrel 3.Sealing ring 6 is rubber ring.
During installation, technical staff first mandrel 3 is arranged in the first support body 101, then mandrel 3 is extended the first support body
101 one end correspondence is arranged in the second support body 102, then is fixedly connected with the first support body 101 and the second support body 102 with bolt
Come；During work, outer circle rack 1 rotates with respect to mandrel 3.By arranging at least two groups steel ball groups 2, stable support is played to mandrel 3
Effect, it is to avoid mandrel 3 radial direction is rocked；First support body 101 and the second support body 102 are installed separately, then with bolt by the first support body 101
Be fixedly linked with the second support body 102, technical staff install when convenient, installation accuracy is higher, it is to avoid mandrel 3 install less than
Position.This bearing makes spindle axis of false twister stability of rotation, and amplitude is little, and reliability is high, and service life is longer.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents it is not necessary to performing creative labour just can be special to some of which technology
Levy and make some replacements and deform, these are replaced and deformation is all in protection domain of the present utility model.
