Abstract (en)
[origin: EP1895033A2] Thread tension compensating rollers (5) are held in bearings in the rotor head. One of the bearing bores (2a, 2b) has a connection (11) for lubricant supply. These bores are connected by a passage (9). The connection- and passage bores are coaxial with the rotary axis (14). The connection is close to the twist head rotary axis. It is coaxial with one of the bearing axes (3a, 3b). Spacer rings (7) are located in radially-surrounding grooves of the bearing bores. Within each groove, a surrounding channel recess (8) is formed. Its cross section is smaller than that of the groove. This prevents each spacer ring from touching the base of the recess. Each ring includes a circumferential interruption which opens the bore (9) locally, for lubricant supply to the roller bearings. Movement of the spacer ring is limited by an elevation (12) in the groove, adjacent to the lubricant passage bore.
