Electronic dobby with positive lubrication

Abstract

The invention discloses an electronic multi-arm machine having an active lubrication function. The electronic multi-arm machine comprises a box body, a power input shaft, a spline shaft and a cam driving mechanism. The axial center of the spline shaft is provided with a spline shaft oil-guide channel along a direction parallel to a length direction of the spline shaft. The front end of the spline shaft is provided with an oil inlet seal bearing installation hole. An oil seal bearing is arranged in the oil inlet seal bearing installation hole. The spline shaft oil-guide channel is communicated with an oil inlet seal bearing inner ring hole of the oil inlet seal bearing. The middle of the spline shaft is provided with a spline shaft oil outlet channel. The spline shaft oil outlet channel and the spline shaft oil-guide channel form a cross-staggered relationship and the spline shaft oil outlet channel is communicated with the spline shaft oil-guide channel. An active lubricating oil supplying mechanism is arranged in the position corresponding to the front side of the oil inlet seal bearing inner ring hole in the box body cavity. The active lubricating oil supplying mechanism is connected to an oil path of the oil inlet seal bearing inner ring hole and is transmission-connected to the power input shaft. The electronic multi-arm machine has good whole lubricating effects and helps to prolong service lives of the eccentric plate, eccentric disc bearing and swing arm.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to an electronic dobby with active lubrication function. Background technique [0002] The electronic dobby is one of the opening parts of the loom that converts the pattern signal of the fabric into the opening action and drives the heald frame of the loom to lift up and down. For this, please refer to the patent documents that are not limited to the following examples: CN102400257B ( Rotary dobby shedding mechanism), CN102995212B (selection actuator of rotary dobby shedding device), CN105442138B (three shedding device of rotary electronic dobby) and CN101709525B (three shedding mechanism of rotary electronic dobby ),etc. [0003] image 3 Shown is a schematic diagram of an electronic dobby in the prior art, including a box body 1, a power input shaft 2, a spline shaft 3 and a cam transmission mechanism 4, the box body 1 is supported on a frame in use, and th...

Problems solved by technology

However, for the above-mentioned eccentric disc bearing and the contact surface between the eccentric disc and the swing arm, the lubrication effect is relatively lacking, because the lubricating oil acts on the eccentric disc bearing and the contact surface between the eccentric disc and the swing arm in a negative rather than positive manner. Lubricated, the negative way refers to the infiltration of lubricating oil from the outside to the inside, which belongs to passive lubrication. It is difficult or even impossible to obtain the desired comprehensive or overall lubrication effect between the eccentric disc bearing and the contact surface between the eccentric disc and the swing arm, resulting in The service life of the eccentric disc bearing and the swing arm is affected
