Chain drive mechanism of warp knitting machine

Abstract

The present invention discloses a warp-kitting chain transmission mechanism, which comprises a drive device, a drive shaft driven by the drive device, a chain wheel and a chain meshed with the chain wheel for transmission. The chain transmission mechanism also comprises a distensible connector for fixing and connecting the chain wheel on the drive shaft. The distensible connector comprises an external barrel with an external flange, an internal barrel with an external flange and a first bolt arranged between the external flanges of the internal barrel and the external barrel; or a barrel with an external flange and a second bolt arranged on the external flange of the barrel. The connection between the chain wheel and the drive shaft of the present invention has no gap, the distance between chain wheels can be arbitrarily adjusted, the transmission accuracy is high and the service life is long; therefore, the present invention can be promoted and applied in the warp-knitting equipment.

Description

technical field [0001] The invention relates to a transmission mechanism of a warp knitting machine, in particular to a chain transmission mechanism for a multiaxial warp knitting machine. Background technique [0002] The existing warp knitting machine chain transmission mechanism comprises a motor, a drive shaft driven by the motor, a sprocket wheel and a chain meshed with the sprocket wheel, the sprocket wheel and the drive shaft are all provided with keyways, and the sprocket wheel and the drive shaft connected by keys. In the chain transmission mechanism of this structure, on the one hand, there is inevitably a gap between the key and the sprocket and the keyway of the drive shaft due to manufacturing errors. With the continuous movement of the chain, this gap will also become larger, so that the key and the The mutual collision between the sprocket and the driving shaft is intensified, thereby shortening the service life of the sprocket and the driving shaft, reducing...

Problems solved by technology

In the chain transmission mechanism of this structure, on the one hand, there is inevitably a gap between the key and the sprocket and the keyway of the drive shaft due to manufacturing errors. With the continuous movement of the chain, this gap will also become larger, so that the key and the The mutual collision between the sprocket and the driving shaft is intensified, thereby shortening the service life of the sprocket and the driving shaft, reducing the transmission accuracy, and the noise is also large during work, which affects the health of the operator; on the other hand, due to the keyway in the active The processing position on the shaft is fixed, so the distance between the sprockets installed on both sides of the drive shaft cannot be adjusted, which makes the installation and maintenance of the sprockets very inconvenient
