Water spraying loom battening shaft waterproof ring

Abstract

The invention relates to a water spraying loom battening shaft waterproof ring. The ring is used in cooperation with a battening shaft, a bearing shell seat and a bearing shell; the ring has the advantages of simple structure and low manufacturing cost, components are of split semi-circular structures, and are mounted on the bearing hell seat, and the ring is convenient to maintain and disassemble; an outer ring main frame tightly fits a bearing shell seat mounting groove, a waterproof ring does not rotate with a battening shaft, and is static relative to the bearing shell seat to prevent water from entering the joint between the waterproof ring and the bearing shell seat, an inner ring is provided with oil sealing lips on both sides and an intermediate oil groove to form triple waterproofprotection, and the waterproof ring is highly waterproof; at least one opening is formed in the inner side oil sealing lips to provide convenience for the extrusion of inner bearing shell lubricatinggrease in a substantially uniform state, the lubrication of a bearing shell structure is not affected, and the waterproof efficiency is improved. The waterproof ring enables the battening shaft bearing shell structure to be used normally for a long time in a water bath environment, and is easy to maintain.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a water-jet loom beat-up shaft waterproof ring. Background technique [0002] In the current water-jet loom market, more and more water-jet looms use solid beating shafts supported by bearing pads to replace the old hollow barrel beating-up shafts without bearing pads to increase the beating strength. To meet the weaving needs of more new chemical fiber fabrics. Once the bearing pad support is used, the waterproof problem of the bearing pad seat section of the beating shaft will be highlighted, because the beating shaft of the water jet loom works in a water bath state, and the shaft section combining the bearing pad and the shaft cannot be done. For surface anti-corrosion treatment such as paint, if the shaft section at the bearing pad is infiltrated with water, the shaft will corrode and rust soon, and at the same time, the bearing pad will wear and fail, and the ent...

AI Technical Summary

Problems solved by technology

Once the bearing pad support is used, the waterproof problem of the bearing pad seat section of the beating shaft will be highlighted, because the beating shaft of the water jet loom works in a water bath state, and the shaft section combining the bearing pad and the shaft cannot be done. For surface anti-corrosion treatment such as paint, if the shaft section at the bearing bush gets water, the shaft will corrode and rust soon, and at the same time, the bearing bush will wear out and fail, and the whole beating shaft will need to be scrapped

[0003] The waterproof ring of the existing water-jet loom beat-up shaft bearing shell seat section mostly adopts a full-circle rubber ring labyrinth seal structure, which has the following disadvantages: 1. The seal ring rotates with the beat-up shaft, and the The bearing seat cannot fit tightly, and there will be a small amount of water ingress; 2. The rubber material has an aging cycle. Once it is aged, it will harden and deform, which will significantly reduce the waterproof effect. It is necessary to replace a new waterproof ring. The replacement process is complicated and requires Remove the whole beat-up shaft

waste of time, labor

These disadvantages will not only reduce the service life of the beating shaft, but also reduce the weaving efficiency of the water jet loom due to the long maintenance time
