<p>The present invention provides an individual-spindle-drive type multiple twister having a motor to directly rotate a spindle shaft of a twisting unit. A bearing support portion for rotatably supporting the spindle shaft via a bearing is formed on the housing of the motor with a stator fixed thereto. Each bearing support member (27, 28; 77, 78) has a lubricating oil supply port (26c, 27c; 76c, 77c) for externally supplying a lubricating oil to the bearings (27a, 28a; 77a, 78a) and a lubricating oil passage (26d, 27d; 76d, 77d) that guides the lubricating oil from the lubricating oil supply port to the bearing, and the lubricating oil passage is located along the outer circumference of the bearing. Thus, the lubricating oil can be externally supplied while the spindle shaft is being supported, thereby simplifying the lubricating oil supply operation and enabling the individual-spindle-drive type multiple twister to be more compact. In addition, the lubricating oil can be easily supplied to the bearing while keeping the height of the twisting unit to a minimum (Fig. 4). <IMAGE></p> |
