摘要： A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is not wasted, and which does not impair work environment by contaminating floor surface etc. A traction drive power transmission device has at least one drive roller (12a), a follower roller (12b), and a circular cylinder-like shaft (11). The shaft (11) is held between the drive roller (12a) and the follower roller (12b). When the drive roller (12a) is rotated, rotational force by the rotation is transmitted to the shaft (11) to drive it in its axial direction. The device has a lubrication oil-delivering portion (20) with application bodies (22-1, 22-2) for applying a lubrication oil only to portions where the shaft (11) is in contact with the drive roller (12a) and the follower roller (12b).
摘要翻译： 本发明提供一种牵引驱动力传递装置，能够将润滑油长时间稳定地连续地施加于辊与轴相接的部位，因此不会在接触部产生润滑油不足， 润滑油不浪费，并且不会污染地板表面等，从而不会损害工作环境。牵引驱动力传动装置具有至少一个驱动辊（12a），从动辊（12b）和圆筒状轴（ 11）。 轴（11）被保持在驱动辊（12a）和从动辊（12b）之间。 当驱动辊（12a）旋转时，由旋转产生的旋转力被传递到轴（11）以沿轴向驱动它。 该装置具有带涂抹体（22-1,22-2）的润滑油输送部分（20），用于仅将润滑油施加到轴（11）与驱动辊（12a）接触的部分和 从动辊（12b）。

摘要： In order to provide a long-life, highly-reliable guide apparatus which exhibits dustproof performance and prevents intrusion of dust into the moving block in environments where there are lots of fine dust such as gypsum and ceramic powder and where no oil contents or oil contents are not liked, there is provided a guide apparatus having a track rail 11, in which rolling-element raceway grooves 12-1 to 12-4 are formed along a longitudinal direction thereof, and a moving block 20 attached to the track rail by way of a plurality of rolling elements in a relatively-movable manner, wherein an end-face dustproof brush 25, which has a brush member 36 whose tip end contacts a surface of the track rail 11 and which eliminates extraneous matters adhering to-che surface of the track rail 11 by means of the brush member 36, is attached to outside of each of the side covers 22 with respect to the direction of relative movement.

摘要： A guide apparatus including a track rail and a moving block is free from the possibility of foreign matter entering the moving block through the gaps between the side surfaces of the track rail and the inner side surfaces of the moving block even in an environment where many fine dust particles are flying. A guide apparatus has a track rail and a moving block 20 relatively movably attached to the track rail with rolling elements interposed therebetween. The rolling elements recirculate through rolling element recirculation passages. Foreign matter entry preventing plates 34 are provided so that their respective distal ends longitudinally contact the opposite side surfaces of the track rail to close the gaps between the side surfaces of the track rail and at least the inner side surfaces of skirt portions on both sides of a moving block body 21 and the inner side surfaces of end plates of the moving block 20.
