Linear movement device and lubricant supplying device used therefor

Abstract

The present invention relates to a linear movement device, for example, a linear guide device, a ball screw, a ball spline or the like in which a track shaft and a slide member is engaged movably relative to each other via a rolling element of a ball, a roller or the like, in details, to an improvement of a linear movement device having a lubricant supplying member coating a lubricant on a face of the track shaft. The linear movement device is constituted by a track shaft where a rolling face of a rolling element is formed, a slide member engaged with the track shaft via the rolling element and moved relative to the track shaft and a lubricant supplying member mounted to the slide member and coating a lubricant on a surface of the track shaft in accordance with the relative movement and further, the lubricant supplying member includes a lubricant coater brought into contact with the track shaft for coating the lubricant on the track shaft, a lubricant absorber installed contiguous to the lubricant coater for supplying the lubricant to the lubricant coater while absorbing the lubricant and holding the lubricant and oil amount controlling means for controlling an amount of the lubricant supplied from the lubricant absorber to the lubricant coater.
