摘要
A planet guide roller welding wire feeding arrangement having at least two planet guide rollers rotatably mounted on a bearing part with the axes of rotation thereof defining an angle with the welding wire axis and are arranged radially outwardly from the welding wire axis. The bearing part encircles the welding wire and is supported for rotation with respect to the welding wire. The bearing part consists of a cylindrical sleeve having a slotted wall structure so that at least two parts thereof are movable toward and away from each other. The guide rollers are rotatably mounted on these two movable parts so that the guide rollers can be adjustably moved toward and away from each other. Structure is provided for facilitating the adjusting of the guide rollers toward and away from each other, which structure is responsive to a relative axial movement between a gripping member encircling the bearing part and selectively fixedly secured thereto.
