SPINDLE'S SPLIT NUT

摘要

The proposed solution concerns a construction arrangement of a spindle nut pivoted in the industrial armature stirrup head. The purpose of the solution is to achieve stability of the arrangement of the upper part of the spindle nut, and to reduce dimensions of the armature stirrup head and of the spindle nut itself. The principle consists in the fact that the transmission element of the torque moment from the upper part (1) to the lower part (2) of the spindle nut is formed by at least one projecture (120) on one part (1) of the spindle head and by at least one groove on the second part (2) of the spindle nut and/or vice versa, where both parts (1, 2) are secured in operating position by means of a cap nut (8) equipped with external thread (82), by means of which it is mounted in the head (50) of the armature stirrup (5) and while the roller bearings (6, 7) are of the same diameter.<IMAGE>
