Synchronised rotary link

摘要

The synchronised rotary tripod link has a link outer part provided with three peripherally distributed, axially running guide tracks and two counterposed guide surfaces. A radially directed pin corresponding to the guide tracks is provided in a link inner part, and on the pin is located a roller arrangement with an outer roller located via a needle bearing on an inner roller.The outer cover surfaces of the outer roller in an area corresponding to the support length of the needle bearing is formed conically, narrowing radially outwards. The surfaces (9) of the guide tracks (12) are parallel to the axis of the link outer part (1) and the radial central lines of the guide path.
