Wire twisting bearing and wire twisting machine

Abstract

The invention provides a wire twisting bearing and a wire twisting machine, and relates to the field of wire production equipment. The wire twisting bearing is mounted on the wire twisting machine; the wire twisting bearing comprises a cage, a support bearing, an outer ring, an inner ring, a shaft tube and a rolling body; the inner ring sleeves one end of the shaft tube, and is fixedly connected with the shaft tube; the support bearing sleeves the shaft tube; the inner ring and the outer ring are rotationally connected through the rolling body; the rolling body is connected with the cage, and the cage is positioned, so that the centroid of the rolling body is fixed relative to the cage, and the cage is fixedly connected with a base; and when the outer ring rotates, the inner ring is driven to rotate by transmission of the rolling body. Compared with a traditional conventional bearing, the inner ring and the outer ring can relatively rotate in opposite rotating directions, so that the relative rotating speeds of the outer ring and the inner ring are greatly accelerated; and for the wire twisting operation, under the condition of the same power input, the wire twisting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of wire making devices, in particular to a twisting bearing and a twister. Background technique [0002] In people's lives, various threads are used to make various daily necessities such as cloth, parcels, etc., and the process of making suitable threads inevitably involves the process of twisting. With the continuous advancement of industrialization, twisting Machines have also become important machinery in industrial production. A twister is a textile machinery that twists multiple strands of spun yarn into one strand. The function is to process yarn or combined yarn products into linear products for weaving and knitting. [0003] And an important part of the twister is the twisting bearing, and the existing twisting bearing usually fixes the inner ring and the outer ring rotates around the inner ring, or fixes the outer ring and rotates the inner ring around the outer ring. Relative rotation for twisting operat...

AI Technical Summary

Problems solved by technology

With the development of industrialization, there are higher requirements for the speed and efficiency of twisted yarns. According to the investigation of the inventors, the traditional twisted yarn bearings can only increase the speed of twisted yarns by increasing the speed of the inner ring or outer ring, while the inner The increase of the rotation speed of the ring or the outer ring has reached a bottleneck period, and it is difficult to increase it significantly, so another way is to be found to greatly improve the efficiency of twisting
