Abstract

The invention refers to a bearing unit and a method for its manufacture incorporating an outer race ring (1), an inner race ring (4) having an inner envelope surface with an axially tapering saw-tooth profile (6), a thin-walled axially slotted sleeve (7), having a tapering saw-tooth profile (9) on its outer envelope surface, cooperating with the saw-tooth profile (6) in the inner race ring (4) for increasing and decreasing the grip of the thin-walled sleeve against a shaft, when inner race ring (4) and sleeve (7) are mutually displaced, a flange (10) connected to the sleeve (7) and having tightening means (11) operable to cause the displacement between sleeve (7) and inner race ring (4), rolling bodies (12) positioned between inner and outer race rings, wherein the surface of the inner race ring (4) presenting the tapering saw-tooth profile (6) has been subjected to a turning operation followed by hardening.

Description

technical field [0001] The invention relates to a simplified rolling bearing unit of the type known as an embedded bearing unit, comprising: an outer raceway ring having a spherically curved outer envelope surface and a circumferential groove provided in the inner envelope surface; an inner raceway ring having Outer envelope surface with circumferential grooves and inner envelope surface of tapered serration profile extending in the axial direction of the inner raceway ring; thin-walled sleeve grooved by axially extending slots and in its There is a tapered serration profile on the outer envelope surface which cooperates with the serration profile in the inner envelope surface of the inner raceway to increase the Clamping of large and small thin-walled sleeves against the shaft; flanges, which are attached to the exterior of the thin-walled sleeves and provided with operable tightening members to cause mutual engagement between the sleeve and the inner raceway ring Displaceme...
