Benefits of technology

This new design improves upon previous designs by changing it from being circular with one more step towards having longer or shorter strokes for each shedding cycle. By doing this, there are increased space between different parts within the shed that can be used during various stages such as inserting yarn through tube holes or adding threads without affecting its overall performance. Additionally, these improvements allow for easier maintenance and control over costs while also allowing for greater flexibility when selecting materials based on factors like weightiness and fabric quality.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance and versatility of an airlover system used during weaving processes such as woven cloth production. Specifically, current systems lack flexibility due to their design and configuration, making them difficult to use across different types of materials without causing damage from excessive pressure applied thereon.

Abstract

The invention discloses a non-circular gear spatial spherical 4R shedding mechanism. The 4R shedding mechanism comprises a pinion which is fixed on a main shaft, wherein the main shaft is connected with a frame through a bearing; a bull gear is fixed on a crankshaft; the crankshaft is connected with the frame through a bearing; the bull gear is meshed with the pinion directly; teeth of the bull gear and the pinion are distributed in a non-circular way; a meshing pitch line between the bull gear and the pinion is non-circular; one end of a spatial connecting rod is connected with the crankshaft through a bearing; the other end of the spatial connecting rod is connected with a swing arm through a conical roller bearing; an included angle between axial leads of the two bearings on the spatial connecting rod is 90 degrees; the swing arm is fixedly connected with a swing arm shaft; the swing arm shaft is connected with the frame through a bearing. An original synchronous pulley is changed into a non-circular gear, so that the approximate dwell time of a heald frame at an extreme position is prolonged, the wefting time can be prolonged effectively, the width of a loom is increased, the variety adaptability of the loop is enhanced, the structural simplicity is kept, and the cost is controlled.
