Embodiment Construction

[0025] figure 1 The spinning spindle 101 representing the state of the art, in its position of use, is mounted on the roving frame B of the ring spinning frame. Here, the headstock 108 has a flange 116 and is screwed to the external thread of the headstock 108 by means of a fastening nut M to be fastened to the roving machine B. In the headstock 108 a bearing housing 109 is accommodated, and in the end section above the roving frame a radial journal bearing 110 forming a roller bearing is pressed in. The neck bearing 110 has a row of rollers or rollers 112 limited by a cylindrical outer ring 111 . A cylindrical outer ring 111 is press fit within the end section of the bearing housing 109 . The support housing 109 includes and carries guide sleeves 113 forming lateral looseness. This guide sleeve is usually made of steel and is provided with helically running grooves 114 . At the end of the displacement of the neck bearing 110, the guide sleeve 113 has an end bearing 115, w...

Abstract

The support for the spinning main shaft of the ring spinning machine, especially the radial bearing (11), including the bearing outer ring (12) connected with the supporting sleeve (7) set in the axial direction and the radial bearing Both protrude axially. The inner surface of the bearing outer ring (12) forms a rolling surface (13) for the rolling elements (14) of the radial bearing (11). The bearing outer ring (12) has a cylindrical shoulder (15) fitted in the direction of its axis, which abuts against the rolling surface (13) used by the rolling elements (14). The wall thickness (w) of the cylindrical shoulder (15) is less than 2 / 3 of the wall thickness of the bearing outer ring (12) within the range of the rolling surface (13).

Description

technical field [0001] The present invention relates to a support for a spinning main shaft of a ring spinning machine that meets the general concept of patent claim 1. Background technique [0002] Converting from natural- and man-made fibers to a thread requires a series of sub-processes. The final overall process is usually called worsted spinning. Here, a yarn of final fineness and strength is obtained. Worsted spinning needs to consume all the main thread-making processes, not only time consumption, investment, but also energy consumption must be considered. In modern times, the famous micro-long hang-on ring spinning technology has replaced the traditional hand-spinning process using spinning wheels. Here, as in a conventional spinning wheel, the thread is unwound on a rotating spindle. The difference from a traditional spinning wheel is that it has a unique, relatively slowly rotating spindle, which in the case of a ring spinning frame on a roving frame, is equipp...
