Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a circular knitting machine of the type described in the preamble of claim 1. [Prior Art] This type of circular knitting machine is known to have various variations (for example, f: EP0436313B1, DE 1 95 1 1 949 A 1 , PCT WO 02/053 8 1 7 A1 ). Circular knitting machines are usually constructed as circular knitting machines which, in addition to being provided with a rotatable dial, are also provided with a likewise rotatable cylinder. In the case of a rotatable base of the dial, the bracket is provided with a securely configured dial cam mount in which the dial camshaft is rotatably arranged for driving the dial and is connected to the dial, for example by a rigid support ring . The dial cam has a dial cam member and is used to control the movement of the threaded needle, the threaded needle being configured to be radially displaceable within the dial, the dial cam being secured to the dial cam mount. In addition, the dial cam can have a patterning attachment for selecting a ribbed needle for 2-way technology (knit, non-knit) or 3-way (knit 'picked, non-knitted). The important dimensions of these machines are the space between the underside of the dial cam member and the edge of the dial web. The space is measured parallel to the common axis of rotation of the dial and the syringe, and is hereinafter referred to simply as the gap size. In particular, when a rib needle is selected by an electromagnet for knitting or folding, even a small change in the gap size may result in a poor selection of the rib needle. One reason for the undesired change in the gap size has been found to be in the dial cam mount's pin -5-201002909 disc camshaft base. The dial cam shaft is usually placed in a dial cam mount by means of a ball bearing or the like, which is commercially available as having only unavoidable axial bearing clearance. As a result, unacceptable fluctuations are constantly generated within the gap size, especially in the case of large dial diameters and fine gauges, as well as under the influence of temperature fluctuations during operation of the circular knitting machine. Although these fluctuations are only in the micrometer range, these fluctuations indicate that it is impossible to select the rib needle without mistake. In view of the above, the technical problem underlying the present invention is to construct a circular knitting machine of the aforementioned type such that even with the base of the aforementioned dial camshaft, the ribbing can be selected reliably (especially electromagnetically). needle. SUMMARY OF THE INVENTION The above problem can be solved by the present invention having the structural features of the first claim. The present invention provides the advantage that the dial is directly supported on the disc cam support by bearings which act as a stabilizing bearing that can be adjusted to a preselected bearing clearance, thereby ensuring a substantially constant gap size. Furthermore, since the rotational movement is transmitted from the dial camshaft to the dial by the spring plate, the slight axial displacement of the dial camshaft can be compensated, and the slight axial displacement of the dial camshaft does not affect the needle The axial position of the disc and the desired gap size 〇 In addition, the advantageous features of the invention are known from the accompanying claims. The invention will be described in more detail below on the basis of illustrative embodiments in conjunction with the accompanying drawings. -6-201002909 [Embodiment] Fig. 1 shows a general circular knitting machine having a bracket 1'. The upright support column showing only the bracket 1 in Fig. 1. A stationary lower support ring (not shown) is secured within the bracket 1. The barrel 2 is disposed within the lower support frame, the barrel 2 is rotatable about the axis of rotation 3, and the barrel can be rotated using a conventional drive motor. The general knitting needle 4 is moved in a general manner by the cylinder cam 5, and the knitting needle 4 is disposed so as to be axially displaceable in the cylinder 2. In the upper part of the circular knitting machine, the support column of the bracket 1 is connected to the upper support ring 6, and the upper support ring 6 has a support sleeve 7, the support sleeve 7 and the axis of rotation 3 being coaxial, and the stationary dial cam support 8 The hollow cylindrical portion 8a is disposed within the support sleeve 7. The upper end of the cylindrical portion 8a has an externally threaded section which is screwed into the internally threaded section of the adjustment wheel 9, which is arranged to be axially displaceable but rotatable within the support ring 6. By rotating the adjustment wheel 9, the cylindrical portion 8a and the entire dial cam support 8 can be moved parallel to the axis of rotation 3 in a general manner. The dial cam shaft 11 is rotatably disposed in the hollow cylindrical portion 8a of the dial cam support 8 by bearings 10, such as deep groove ball bearings. The dial cam shaft is configured to be coaxial with the axis of rotation 3 and is fixedly coupled to the drive gear 12. The drive gear 12 is at the upper end ' projecting from the portion 8a and engages the drive pinion 14 on the drive shaft. The drive shaft projects through the support post and the drive pinion for the barrel 2 is also typically secured to the drive shaft to simultaneously drive the dial cam shaft 1 1 and the barrel 2. 201002909 A section of the dial cam support ring 15 is fixed to the lower end of the dial cam shaft 11. The dial cam support ring 15 is located radially inward of the dial 16 and its radially outer section is securely coupled to the dial 16 in a conventional manner; alternatively, the dial cam support ring 15 and the dial In a single piece. A typical rib needle 17 is provided to be radially displaceable within the dial 16. The dial cam 1 8 is used to radially move the threaded pin 17 . The dial cam 18 is fixed to the support flange 8b of the dial cam support 8, which is disposed below the support sleeve 7 and extends radially to the portion 8a. Specifically, as shown in Fig. 2, a general cam portion 19 is fixed to the lower side of the dial cam 18 and is used to control the movement of the rib needle 17. If the pattern is selected for the rib needles 1, the dial cams 18 are additionally provided with selection elements (not shown), for example with electromagnets, so that the electromagnetic selection of the rib pins 17 can be performed in order to select the rib pins 1 7 without mistakes. During the operation of the circular knitting machine, it is desirable to keep the gap size a (Fig. 2) as constant as possible. The gap size is defined between the upper edge of the dial web 16a and the lower side of the cam portion 19a. A rib needle 17 is disposed between the respective webs of the dials 16a. The gap dimension a, compared to the pre-selected chirp even within the micrometer range, represents that the selection of the rib needle 17 is no longer reliable. For example, the unavoidable axial play (Play) in the bearing 1〇 can cause this deviation. A circular knitting machine of the type described above is well known to those skilled in the art and therefore need not be described in further detail. Figures 3 and 4 show an exemplary embodiment of a circular knitting machine of the present invention. The same parts of Figures 3 and 4 and Figures 1 and 2 use the same reference numerals. Unlike the Figs. 1-8-201002909, 2, the dial 16 is non-rigidly constructed on or connected to the dial cam support 15, but is coupled to the support ring 21 by, for example, an annular spring plate 20. The support ring 21 is firmly connected to the dial cam shaft 11. The retaining ring 22 is firmly fixed to the dial 16 by bolts 23 and is firmly fixed to the spring plate 20 by another bolt 24. The retaining ring 22 is preferably disposed between the spring plate 20 and the dial 16. According to Fig. 4, the substantially U-shaped bearing groove 25a surrounds the axis of rotation 3, and the first portion of the bearing 26 is disposed within the bearing groove 25a. The bearing groove 25a is constructed inside the support flange 8b or its cylindrical attachment. Other portions of this bearing 26 are disposed within other bearing slots or recesses 25b, 25c. Bearing grooves 2 5b, 25c are constructed on the lower end section of the retaining ring 22 and the lower side of the bearing ring 27. The bearing ring 27 surrounds the axis of rotation 3 in a coaxial manner. The bearing ring 27 is fixed to the upper side of the retaining ring 22 by bolts 24. According to the invention, the bearing 26 is constructed such that its axial bearing clearance (clearance; that is, the clearance parallel to the axis of rotation 3) can be adjusted, and thus allows for the creation of a sufficiently small axial play (P1 ay ) so that The fluctuation of the gap dimension a is as small as possible, but still allows the bearing ring 27 to rotate sufficiently smoothly with respect to the dial cam support 8, and thus the retaining ring 22 and the dial 16 are supported by the bearing ring. The bearing 26 is preferably constructed as a ball bearing having a plurality of bearing balls 28 that move over the bearing surfaces formed by the bearing grooves 25a, 25b, 25c. It is particularly advantageous to use a wire loop ball bearing as the bearing 26 having, for example, four wire loops' which are arranged opposite each other in pairs in the bearing grooves 25a, 25b, 25c. Bearing surfaces for the bearing balls 28 to move on their 201002909 are constructed on the rings. If the retaining ring bearing rings 27 are positioned above each other' then the diameter of the bearing balls 28 is greater than the distance of the bearing surfaces 25b and 25c from each other, the bolts 24 acting by the axis of rotation 3 can be used to adjust the bearing surface 25 in the manner described above. The clearance between b, 2 5 c or the space between the wire loops only requires the bearing 26 to tighten the retaining ring 22 and the bearing ring 27 to each other. The advantage of this countermeasure is that the bearing clearance can be adjusted so that during the operation of the circular knitting machine, the gap size a is almost maintained and the problem of selecting the rib pin 17 is avoided. In accordance with the present invention, the spring plate 20 is used to compensate for any axial fluctuations in the bearing 10, any expansion and compression due to temperature, and the effects of the effects. The spring plate 20 is sufficiently rigid for radial bending to be able to rotate from the dial camshaft rod 1 1 to the dial 16 . However, the spring plate 20 can be deformed axially by at least a few microns, and any axial displacement of the camshaft 11 does not affect the shaft and gap dimension a of the dial 16. Furthermore, because of the elasticity of the spring plate 20, the 16 can always follow any axial position of the dial cam support 8 in this case, the term "spring plate" refers to any variation of the above functions, regardless of Whether it is constructed into a ring, an individual section, or a form. The invention is not limited to the above-described exemplary embodiments, which may be modified individually. In particular, a spare bearing 26 can be used in addition to the above. Again, it is conceivable that the holding ring 22 and the selling 22 are expediently parallel to these axes. In other words, relative to small, unchanged, generated and others, the transmitter moves to the position with the dial. It is contemplated that the discs 16 - 201002909 in other manners are produced in a single piece, and/or at least in parts 21, 22, and/or 27 pieces. Further, in order to accurately adjust the bearing clearance, a spacer disc can be inserted between the retaining ring bearing rings 27. Further, other generation spring plates 20 may be provided to allow for axial fluctuations and adjustment of the dial jaws 6. Attaching the retaining ring 22 to the support ring 21 ' in an axially adjustable manner is apparent. When the syringe 2 is used to adjust the stitch size, the dial support 8 and the dial 16 can be made by the adjusting wheel 9 The desired axial direction, i.e., although the dial cam support 8 is fixed, is configured to be axially adjusted in the holder. Nevertheless, whether or not the circular knitting machine does not have a syringe is absolutely insubstantial for the purposes of the present invention. Finally, 'different structural features can be applied to the above-mentioned and representative of the drawings.
