Description
Technical field
The present invention relates to the rotor spinning device that a kind of band can drive revolving cup; Wherein, Revolving cup has a revolving cup dish and a rotor axis; And revolving cup is bearing at least one journal bearing flying on the rotor axis changeing, and revolving cup has the part that overhangs that a leading edge from the revolving cup dish measures the starting point of journal bearing.
Background technology
For the revolving cup of such rotor spinning device, be devoted to 180 today in practice, 000min
-1The rotating speed of the order of magnitude.With the rotating speed that revolving cup can reach, be to be rated rotational frequency basically with critical speed, because consider security, running speed must be all the time under critical speed.
According to DE 197 29 941 A1, people have recognized the measure that improves critical speed.For example according to regulation, the length of rotor axis approximately should be ten times of its diameter.Really, the measure of regulation is not enough to bring up to 150 to rotating speed, 000min

-1Running speed.
This task is to solve like this, and the part that promptly overhangs is less than 29mm, particularly less than 27mm.
Verified, the part that overhangs of revolving cup has significant impact to the raising of critical speed.Even a small amount of effect of shortening the part that overhangs can obviously improve critical speed.
The part that overhangs of revolving cup should be defined as the distance of the leading edge of revolving cup to the journal bearing starting point.Therefore, it is inessential how designing journal bearing.Journal bearing can be that for example a supporting disk is right, an air bearing, and a magnetic bearing perhaps also can be a rolling bearing.
A revolving cup dish of normally used revolving cup is pressed on the rotor axis, and therefore, in order to compress connection, this part that overhangs must be a very big part.If shorten the length that compresses connection, just must guarantee, can not become flexible under the extreme high rotating speed of revolving cup even compress to connect yet.As if can not obviously shorten the length that compresses connection through combining FEM to calculate the evidence of being done.According to ways of connecting, the part that overhangs that can reach arrives in the scope of 20mm 15.
According to current technical level, be the rotor spinning machine of R20 by its applicant through the model that provides after many years, the overhang of its revolving cup is divided into 25.9mm.But known spinning machine is to be not suitable for high like this rotating speed, because have the revolving cup of the total length of very long 117mm, part is not long though it overhangs, and its critical speed is relatively low.
On a revolving cup that can drive, done test widely by the tangential belt that adjoins rotor axis; Result of the test shows; Rotor axis overhangs the product of part (millimeter) and diameter (millimeter) less than 250 in the tangential belt scope, and this is favourable for reaching high critical speed.On known so far rotor spinning device, the part that overhangs and the product of rotor axis diameter are always greater than 250.For example on the R20 spinning machine of having mentioned, this product is 266.Test verifiedly, the part that overhangs and the product of diameter can be used as the empirical Calculation characteristic value of the relation of description.When the value of characteristic value less than 250 the time, can from conflicting requirement, draw a compromise proposal preferably.In order to reach high as far as possible critical speed, predesignate an as far as possible little part that overhangs, predesignate a big as much as possible rotor axis diameter simultaneously, this itself possibly be significant.But for the tangential belt of transmission rotor axis, the diameter of rotor axis is too big, can cause the speed of service that causes driving belt is brought up to unallowable degree.In addition, under the bigger situation of rotor axis diameter, for example because the increasing of power loss can take place in the increase that rubs in the revolving cup journal bearing.Confirm through test that the characteristic value that multiply by diameter when the overhang branch is in 200 to 230 scope the time, critical speed is so high, to such an extent as to can reach 180 preferably, 000min
-1The operation index.
In addition, the invention still further relates to a kind of being applicable to and have a revolving cup dish is connected a kind of like this rotor spinning device of rotor axis with an antitorque commentaries on classics revolving cup.Predesignate according to the present invention, the product of revolving cup dish length (mm) and rotor axis diameter (mm) is less than 195, preferably in 170 to 190 scope.Such revolving cup can be used for can be with 180,000min
-1The rotor spinning device of running speed operation, be favourable.
When the product of overhang part (mm) and revolving cup total length (mm) less than 3000 the time, can reach the purpose of the extra high rotor spinning device of further optimization running speed.When the product of the length (mm) of revolving cup dish and revolving cup total length (mm) less than 2400 the time, be favourable to revolving cup.
