Description
K. BEE'RLI ,HIGH sPEEnsP1NN1NG 0R TwIsTING SPINDLE Nov. 14, 1950 Filed Feb. 4, 1948 Patented Nov. 14, 1950 y Karl Beerli, Uster, Switzerland, assigner to Spinl del,
Uster, Switzerland' Motoren-und Maschinenfabrik A. G.,
Application February 4, 1948, Serial No. 6,286 In Switzerland February "I, 1947 Claims. (Cl. 308-228) The invention relates to a high-speed spinning or twisting spindle with an oscillatory bearing sleeve, so arranged for known reasons. According to the invention, the top portion of either the bearing sleeve for accommodating the spindle shaft or of the spindle housing is provided with transverse slots in order to flexibly support the bearing sleeve on the circumference; This enables to obtain in a simple manner a suitable oscillatory mobility of the spindle shaft.
In the drawing are represented a. number of executional forms of the invention. Are illustrated in:
Figs. l to 4 longitudinal sectional elevations of executional forms,
Fig. 5 elevation and transverse section of the slot arrangement according to Fig. 4, whereas Figs. 6 and 'I show elevations and transverse sections of further examples of the slot arrangement.
In the drawing, which is limited to parts necessary for explaining the invention, in Fig. 1 a bearing sleeve I is provided for accommodating the shaft of a spinning or twisting spindle and it` may possess at its interior end a damping device of any known kind.
A schematically indicated roller bearing 3, serving as a lateral guide for the spindle shaft, is provided in a known manner in the extended head 2 of the bearing sleeve I. A spindle housing of the usual construction made from cast iron, for example, is indicated in 4. At the top portion of bearing sleeve I is arranged a jacket 5 free on the inside, which represents a downward extension of head 2. By means of this jacket 5 the bearing sleeve I is inserted into a turned portion on the inside of the top part of the spindle housing 4, such turned portion being widened at the top edge of the spindle housing 4, the jacket 5 possessing circumferential clearance over the corresponding distance. In the jacket 5 two narrow slots 6 and 1 are arranged in each of two transverse planes in such a manner that the two slots 6 and 'I positioned in the same plane are diametrally opposed. The pairs of slots 6 and 'I are mutually staggered in the circumferential direction of the jacket 5 and the bearing sleeve I respectively.
The bearing sleeve I is fixed radially or transversally respectively in the spindle housing 4 by means of the jacket 5, as far as this is necessary for the working. On the other hand, due to the slots 6 and 1 provided in the jacket 5, acertain axial movement of the bearing sleeve I is possible during working as well as an oscillatory motion about a centre located in the region of the top support of the bearing sleeve I. The ilexible supporting provided by the jacket 5 to the bearing sleeve I on the spindle housing 4 tends to keep the bearing sleeve I and the spindle shaft respectively in their central position.
In the described arrangement of the oscillatory suspension of the bearing sleeve I at its superior extremity it is possible to provide the same diameter for the top end of spindle housing 4 and the head 2 of bearing sleeve I, which represents an advantage for arranging the usual driving whirl.
Contrary to the executional form according to Fig. 1 where the jacket 5 is solid with the bearing sleeve I and the head 2,in the executional form according to Fig. 2 the jacket 5 and the head 2 form a separate piece. The connections of this piece with the tubular part of bearing sleeve I is obtained by inserting over and outside the turned portion of this tubular part a ring 8 on the top edge of which rests an inside-collar 9 of the head 2, an outwardly extending ange I0 of the said tubular part engaging a chamiered portion of the collar 9.
The executional form according to Fig. 3 dii'- fers from the one described previously in that the top edge of the spindle housing 4 is positioned lower with respect to bottom of head 2 of the bearing sleeve I. The difference is equal to the length of the widened turned portion according to Fig. 2 at the top end of the spindle housing 4 (in the sense of Fig. l).
The executional form, according to Fig. 4 differs from those described in that the pairs oi' slots 6 and 1 positioned in two transverse planes 'are arranged not on the bearing sleeve I, but on the spindle housing 4. Thus, the jacket 5 such as it has been provided in the executional forms according to Figs. 1 `to 3, becomes superfluous.
According to Fig. 5, a web II and I2 respectively is left between each of the two slots 6 and 1 respectively which are arranged in the same transversal plane of the spindle housing 4; the pairs of slots 8 and 1 are mutually staggered circumferentially, as may be seen in the sectional view. The connection between the non-slotted portions of the spindle housing 4 is obtained by means of the diametrally opposed webs I I and I2. 'I'he executional form according to Fig. 6 differs in that the spindle housing 4 possesses in the same plane three slots 6 and 1 respectively with the corresponding three webs II and I2 respectively. These three webs II and I2 respectively are equally distributed over the circumference of the 3 spindle housing 4. The two groups of slots l and 1 staggered with respect to one another in the axial direction on the spindle housing 4, are circumferentially staggered, as mayrbe seen in the sectional view of the drawing. In this sectional View the dash-dotted arcs i3show how the slots i and 1 may be cut in the body of the spindle housin'r 4 by means oi' a milling cutter of suitable diameter.
According to Fig. '7 the-spindle housing 4 possesses diametrally-opposed transverse slots 8 and 'i extending over more than half the circumference of the spindle housing 4. All four slots are therefore staggered in the axial direction of thev spindle housing 4: the two between consecutive slots B and lfollowing axially with respect to spindle housing 4, a web I4 is left (Fig. 7).
It is clear thatthe slot arrangements of the kind described (Figs. 6, 7) may also be provided on the jacket of the bearing sleeve I instead of the spindle housing 4. It is also clear that other kinds of slot arrangements are possible for the object in view.
What I claim as new and desire to secure by Letters Patent is:
l. In a high speed spinning. spindle mounting, a bearing sleeve for holding the spindle shaft, a bearing housing for holding the said bearing sleeve, `said bearing sleeve and spindle housing beins.r united toward their outer ends into a unitary body. by mutually interilttinar portions one of said portions near the location of the interfitting being provided in different transverse planes with a plurality of slots, the adjacent groups of slots being l 4 peripherally oil'set with respect to each other so that attachment bars will be produced that are correspondingly oilset with respect to each other. fartsthe connecting bars resulting from the cross s o 2.' A spinning spindle mounting according to claim 1 and wherein slots are provided in one o! said portions that lie diametrically opposite each other in one and the same transverse plane.
3. A spinning spindle mounting according to claim 1 and in which two pairs of slots are disposed in one of said portions in overlapping relationwith respect to each other.
4. A spinning spindle mounting according to claim l, and in which plurality of slots are provided in the bearing housing and said slots are in overlapping relation to each other.
5. A spinning spindle mounting according to rclaim 1 and in which the connecting bars are of rectangular cross section.
