DD210714A1 - COMPACT TOOTH RING FOR FIBER DISCONNECTION ON OPEN END SPINNING MACHINES - Google Patents

Abstract

This compact ring is provided for attachment to Walzenkoerpern the Aufloeseelemente. It has a special external toothing, which is mechanically produced in helical turns and in a certain angle of inclination. The ring allows a simple way of attachment with threaded, centering and Fuhrungbohrung and thus a problem-free replacement. Through its homogeneity of materials, it promotes or enables various surface treatment processes for wear part fixing.

Field of application of the invention

The invention relates to all open-end spinning machines in which the thread-forming technology involves a lesser degree of dissolution of paser clumps or separation of fibers.

Characteristic of the Known Technical Solutions Hitherto known dissolving elements or separating elements for fibers on open-end spinning machines are _:. Roller bodies equipped with a helically wound sawtooth wire or pins or needles inserted in grooves or ring cages · A great deal of technical and economic effort is required for the manufacture and replacement of these strongly wearing elements.

The essence of the invention

The object of the invention is a ring with a special external toothing · The design of the toothing is according to the type of fiber to be machined, the ring consists of a part. It is fastened on a one-piece roller body by means of a thread and an associated centering and guide bore, or on a joinable two-part roller body by means of clamps · Interchangeability is ensured with the aid of simple tools and without additional machining. Due to the low net mass of the Kömpaktzahnringes a repeated dynamic balancing the complete rolls can be omitted. The material homogenous compact ring is favorable for the application of different surface hardening surface treatment methods. - ... '/. :! -, -;: ^; ./ ^{;;:; :} ^ V ' ^V 4 ,; _; , ;,;:
