Bearing unit with eccentric clamping collar

Abstract

A bearing unit (10) has: a fixed radial outer ring (31); a radial inner ring (33) which rotates around the central rotation axis (Y) of the bearing unit (10); at least one row of rolling elements (32) between the radially outer ring (31) and the radially inner ring (33); an eccentric collar (20) used to clamp the radial inner ring (33) on the rotating shaft (S); and a first pressure member (21), on the eccentric collar (20). The eccentric collar (20) is provided with a second pressure member (22), which increases the grasping ability of the bearing unit (10) on the rotating shaft (S).

Description

technical field [0001] The invention relates to a bearing unit provided with a collar for clamping a radially inner ring on a rotating shaft. Due to the simple and economical manufacture of such a bearing unit, such a bearing unit is suitable for use in the manufacturing sector, especially in the agricultural sector. [0002] In particular, the bearing unit according to the invention is provided with rolling elements and has an optimized clamping system which proposes the use of an eccentric clamping collar capable of simultaneously locking both the shaft and the radially inner ring , thereby making the two components fixed relative to each other. Background technique [0003] Known bearing units are provided with rolling elements and systems for clamping the bearing unit on the rotating shaft. [0004] Bearing units are used to allow relative movement of one component or assembly with respect to another. Typically, a bearing unit has a first element (eg, a radially inner...
