Active rotating steel collar

Abstract

The invention relates to an active rotating steel collar. The steel collar is structurally characterized in that a hollow shaft motor is fixedly connected with a steel collar plate, a through hole isformed in the steel collar plate, a central shaft of a hollow rotating shaft of the hollow shaft motor penetrates the center of the through hole, the steel collar body is fixedly connected with the outer end of the hollow rotating shaft, a runway is arranged on the steel collar body, and a traveler is arranged on the runway. The steel collar has the advantages that the relative angular velocity ofthe traveler and the steel collar is reduced, the breakage rate is reduced by about 45%, and production efficiency is improved; the spindle speed can be increased by 50%, the front roller speed withthe same twist is also increased by 50%, and the single spindle output of a spinning frame is increased by 50% or higher; the diameter of the steel collar is increased, the cop capacity is increased,the doffing frequency is reduced, and the number of doffing workers is reduced; the service life of the traveler is greatly prolonged by 1-2 months, and labor intensity of the workers is reduced; when the variety of products is changed, all that is required is to change the rotating speed of the steel collar, the traveler is not needed to be changed, and the workload of knitters is reduced; yarndamage caused by heating of the traveler is reduced, and yarn quality is ensured.

Description

technical field [0001] The invention relates to an active rotary steel ring. Background technique [0002] The steel ring is a steel ring-shaped machine that plays the role of twisting and winding in textile machinery such as ring spinning frame and ring twisting machine. The "ring" of a ring spindle refers to the ring. The wire ring on the steel ring is set on the protruding edge (also known as the runway) on the steel ring, and the yarn drives the wire ring to rotate on the steel ring runway during spinning. When the traveler makes one revolution, the yarn is twisted. Travelers are generally small notched circles bent from steel wire. When it rotates on the steel ring, it slides against the inner side of the steel ring runway due to the centrifugal force. [0003] The relative speed of the traveler and the steel ring is very high, which will cause wear and high temperature (above 300°C) due to friction, which will cause the traveler to fly off, burn out or rotate unsta...

AI Technical Summary

Problems solved by technology

However, the rotary rings in the prior art are generally designed for transmission, and structures such as transmission belts need to be installed, which are prone to wear and tear and have a short service life; there are also designs that use ball bearings and dynamic pressure air bearings to realize the rotation of the steel ring, but the structures are very complicated. Prone to failure, cumbersome installation and maintenance, not suitable for popularization
