Specific embodiment
With reference to above-mentioned attached drawing, free end type spinning machine is indicated generally in appended drawing reference 4.
Free end type spinning machine 4 includes at least one work station 8 or unit;Each work station 8 or unit include free end Type spinning apparatus 12 and winding device 13.As it is known, in each free end type spinning apparatus 12, silver fiber 14 is from phase Extraction and spun yarn 15 in the spinning pot (not shown) answered.Yarn is then rolled up on winding device 13 to be formed not in attached drawing Shown in package (or cone of cross winding).
Combing roller (opening roller) 17 is set in each work station, and it is single fine to be formed to open silver fiber 14 Dimension.Then, single fiber is transported to spinning rotor 18, which is transformed into yarn 15 for single fiber.
Each package (package) is frictionally driven by reel 19 to rotate.Reel 19 is arranged on spool 20.
Each of work station, which has, is arranged in the Yarn reeling roller 22 batched in drive shaft 23.
The Yarn lateral-movement device 24 including yarn guide 25 is provided in each work station 8.Yarn guide 25 passes through yarn guide Bar 26 is controlled to carry out longitudinally reciprocating motion.
In addition, spinning machine (can not describe) herein equipped with a number of other devices, such as being automatically changed to product yarn The system of package.Work station can be equipped with piecing devices.Spinning machine can also be with the system for being ready for use on automatic joint.
As described above, work station 8 is provided with combing roller 17 and spinning rotor 18, which is configured to open silver-colored fibre To form single fiber, the spinning rotor is used to single fiber being changed into yarn 15 dimension 14.
Particularly, spinning rotor 18 is contained in shell 28 and by least one bearing 36,40, especially first bearing 36 and second bearing 40 or two rows of different bearing 36,40 be rotatably supported around axis X-X.
Rotor bearing 36,40 may include ball bearing, roller bearing and/or needle bearing and/or sliding sleeve bearing.
The definition of bearing is considered as general and unrestricted.
For example, bearing may include the support unique retainer of two or more rows ball/ball element, or support The different retainers spaced apart of ball/roller bearing in a row.
Advantageously, shell 28 includes about respectively plane M by separated and support the first of the bearing 36,40 to press from both sides Tool 42 and the second fixture 44.
First fixture 42, the second fixture 44 pass through the fixation device 48 that can be removed and are connected with each other, which makees With in the lateral surface 68 of the fixation of outside on the first fixture 42 and that the first fixture is pressed against to bearing 36,40.
First fixture 42 and the second fixture 44 can correspond to corresponding support 52 and contact, the support relative to it is vertical flat Diametrically, perpendicular is perpendicular to respectively plane M and passes through axis X-X by face V.
First fixture 42, the second fixture 44 are symmetrically moved preferably with respect to the perpendicular V.
According to possible embodiment, the fixation device 48 that can be removed includes elastic device 54, so that it is guaranteed that being inserted in The elasticity compacting and installation of at least one bearing 36,40 between first fixture 42 and the second fixture 44.
According to one embodiment, the elastic device 54 includes resilient sleeve 55, and each resilient sleeve 55 is clamped at phase Around the lateral surface 68 of the fixation of the outside for the bearing 36,40 answered.
Preferably, the fixation device 48 that can be removed includes the pressurizer pushed against the first fixture 42 on second fixture 44 56。
For example, the pressurizer 56 includes the cam pin 60 of rotatable self-retaining, to set 42 He of the first fixture Clamping force between second fixture 44.
Preferably, the cam pin 60 of the self-retaining is moved along the transverse axis Y-Y vertical with axis X-X;This Outside, the cam pin 60 of the self-retaining moves preferably on the first fixture 42 so that the first fixture 42 is pushed against the second fixture On 44.
Preferably, the cam pin 60 of the self-retaining along axis X-X the first and second rotor bearings 36,40 it Between move.
According to possible embodiment, the cam pin 60 of self-retaining is connected to operating stick to set the angle with fixed pin itself Orientation and the pressure between the first fixture 42 and the second fixture 44.
The lateral surface of each first fixture 42 and the second fixture 44 relative to the fixation of the outside of corresponding bearing 36,40 68 be in form fitting (counter-shape).
Preferably, the first fixture 42 surrounds the lateral surface 68 of the fixation of the outside of each rotor bearing 36,40 At least 60%.
It is highly preferred that the first fixture 42 surrounds the lateral surface 68 of the fixation of the outside of each rotor bearing 36,40 extremely Few 80%.
According to one embodiment, first fixture 42 is connected to the fixation device 48 that can be removed, and the second fixture 44 is solid Surely shell 28 is arrived.
Above description is related to single work station 8, but the application is suitable for free end type spinning machine 4, which spins Yarn machine includes the multiple work stations 8 for being arranged in a side-by an at least row, and each work station includes having relevant first fixture, 42 He Spinning rotor 18, bearing 36,40 and the fixation device 48 that can be removed as discussed previously of second fixture 44.
As it may infer that in description, overcome according to the free end type spinning machine of the application referring to cited The shortcomings that prior art refers to.
Particularly, rotor bearing/installation system is uniformly fixed in rotor case by the application: the row of bearing is fixed And the case where being pressed with identical pressure with power having the same.
The solution is configured to two dishes or half-moon-shaped component, and one of component/half-shell, which is integrated or is applied to, to be turned In subshell, and another component/half-shell is separated, to slightly neatly be moved to ensure to fill by another The clamping set.
The geometry of two " half a month " components, which is ensured, equably " guides " area arranged to ball by clamping the power generated.
The application ensures accurately to clamp by fixed geometry, and the geometry of the fixation is preferably configured as dish Shape/" semilune " component.This geometry ensure in the region of bearing groove (ball or other rolling elements) it is symmetrical/ Equal fixation/clamping force guiding.
Therefore, the fixation of clamping force ensures the safety of rolling element and stable position during spinning.
It spins in addition, the insertion of the elastic device between the lateral surface of the fixation of the outside of fixture and bearing allows to buffer The vibration of rotor.
In addition, elastic device permission is kept away under different operating conditions (and in the case where the impact to rotor itself) Exempt from the mechanical stress peak value on the bearing of armature spindle.
In addition, the application allows easily to replace armature spindle/bearing arrangement when realizing clamping: in fact, including elasticity The bearing arrangement of installation part can easily remove, without special tool(s), such as by using the cam pin operated by bar.
The main distinction between the prior art and new solution is that old rotor case has oneself far from rotor axis By end sections, so that stable " loaded " position will not be brought to bearing.
The novel solution of rotor case is more symmetrical in terms of rotor axis, thus the distribution of load force it is more good and Uniformly.
In addition, the two sides of resilient mounting are fixed by the power for the determination that can be easy to set by user.
The fixture is the circle that semilune is 80% or more.
In addition, the release of the clamping force of rotor bearing can be realized by the cam pin of self-retaining.In addition, described from solid Fixed cam pin can be handled in the case where no tool (being only used for hand), quickly to safeguard rotor bearing.
Although the specific embodiment of spinning machine has been disclosed, it is understood that, such disclosure is used for the purpose of The purpose of explanation, and spinning machine is not limited in any manner.In view of aforementioned exemplary, to those skilled in the art, Various modifications about the shape of component and position and structure and functionally details will be apparent.
