Wheel module with a roller bearing wheel of a spur gear or traction gear

摘要

The invention relates to a wheel module, comprising a driven wheel (1) of a spur gear mechanism or flexible drive mechanism which is rotatably mounted on a bearing bolt by a coaxial radial bearing (2), wherein the radial bearing (2) comprises at least one row of cylindrical rollers (5) which are held by a radial-bearing cage (4), roll on the inner radial side directly on the bearing bolt or a separate inner bearing ring (8) of the radial bearing (2) arranged therebetween and roll on the outer radial side directly on the wheel (1) or on a separate outer bearing ring arranged therebetween, wherein an axial bearing (3a, 3b) is assigned to both end faces of the radial bearing (2) for combined radial/axial bearing, the cylindrical rollers (7) of which, each being held by an axial bearing cage (6), roll both on a correspondingly external bearing washer (9a, 9b) and on axial bearing surfaces (10a, 10b) formed directly on each flank side of the wheel (1).
