Torsion oscillation damper i.e. fly-wheel, has bearing formed of smooth and ball bearings receiving radial and axial operating forces, respectively, and intermediate space of each of sides of rolling units provided as grease chambers

摘要

The damper has a bearing that is installed between a primary mass (4) and a secondary mass (8). The bearing has rolling units (18) passing in circulation paths (16, 17) in form of gorges of inner and outer rings (14, 15) of the bearing. The bearing is formed of a smooth bearing (12) that receives radial operating forces, and a ball bearing (13) that receives axial operating forces. The units (18) have a spherical shape with lateral surfaces (19, 20) that are parallel and symmetrical. Intermediate space of each of sides of the units (18) is provided as grease chambers (21).
