Pua A DRAG SPINNING WHEEL FOR TANGENT COIL AND BOLT

摘要

Púa drag spinning helical screw tangent wheel in which the teeth of the screw are mounted in a sleeve (6). turns directly into the body. and apparatus. through which the lower end of spindle coil holder (11) with play. which. lies down its tip in a bearing stop (10) is maintained above said sleeve by an upper bearing (8) mounted on said body the fastening taking place in rotation between the sleeve (6) and. spindle (11) by coupling means that allow certain radial relative movements between these two elements characterized in that the lower end of the spindle is arranged in the manner of a centrifugal pump (l3 14) taking lubricant in bath below the worm wheel level and rejects up taking the annular space between the sleeve and the spindle to the level of the upper bearing (8) to which lubricates ensuring continuity lubrication circuit between the top of the sleeve and the upper bearing preferably by said coupling means.
