Spindle pot bearing

Abstract

The invention relates to a spindle pot bearing for a twisting machine, in particular a two-for-one twisting machine or cabling machine, the spindle pot bearing having a bearing bush for connecting a spindle pot base to a spindle in an interlocking manner in an axial direction. In order to provide a spindle pot bearing for a twisting machine that ensures that the position of the spindle pot on thespindle is reliably secured, it is provided that: a first bearing portion of the bearing bush for connecting, in an interlocking manner in the axial direction, to a first bearing member arranged on the spindle has, at a distance with respect to the direction of the longitudinal axis from a shoulder limiting the first bearing portion, latching protrusions which protrude from an inside of the bearing bush and are movable between a blocking position and an unblocking position; a second bearing portion of the bearing bush, said second bearing portion adjoining the first bearing portion in the direction of the longitudinal axis, is designed for interlockingly connecting to the spindle pot base in such a way that locking in the axial direction is possible; and a blocking is arranged on the spindle pot base, which blocking fixes the latching protrusions in the blocking position when the spindle pot base is in an operating position.

Description

technical field [0001] The present invention relates to a bobbin cup holder (Spindle pot bearing) for a twisting machine, especially a two-for-one twister or a direct twisting machine (cabling machine), which has base) is connected to the bearing bush (bearing bush) of the spindle in a form-fitting manner. Background technique [0002] Known twisters, in particular two-for-one twisters or straight twisters, have bearing bushes arranged on the spindles for receiving the bobbin cup bases of the bobbin cups. Known bobbin cup holders often use bearing bushes made of rubber material, the damping material properties of which damp the vibrations occurring as a result of the spindle rotation relative to the bobbin cup. [0003] In order to ensure reliable operation of the twisting machine, a reliable locking of the bobbin cups mounted on the spindles, viewed in the direction of the spindle longitudinal axis, is required. What is important here is that the bobbin cup is locked agai...

Problems solved by technology

However, during processing, especially when twisting yarns with high counts, there is also the danger that, in particular, hooking occurs between the yarn and the bobbin cup when the yarn passes through, whereby the bobbin cup can be inserted from it to be pulled out of position on the spindle, so that not only an interruption of the twisting process but also damage to the bobbin cup may occur
