Abstract: A rotary system includes a first component, a second component, wherein relative rotation between the first component and the second component is operable to occur about an axis, and a bearing. The bearing includes a band, a first washer, a second washer, and a plurality of rolling elements. The first washer is operable to move axially relative to the band and rotate relative to the band. The second washer and the band are non-rotatably connected. The first washer is engaged with the first component at a first axial side of the first washer. The second washer is engaged with the second component at a second axial side of the second washer.

Abstract: A drive assembly including a housing having an opening, a shaft supported for rotation by a bearing assembly received in the opening of the housing, and at least one gear fixed for rotation with the shaft. The bearing assembly includes a bearing that is axially fixed to the shaft, and a sleeve having a tubular section, a radially inwardly extending flange at a first end of the tubular section and a radially outwardly extending flange at a second end of the tubular section. The bearing is received in the tubular section and abuts at least a portion of the tubular section and the radially inwardly extending flange. The radially outwardly extending flange abuts a surface of the housing surrounding the opening of the housing thereby setting an axial position of the at least one gear relative to the opening of the housing.

Abstract: A bearing rolling element with a lattice internal structure provides several advantages over a solid bearing. It is lighter than a solid bearing, reducing centrifugal forces. For ceramic bearings, less material is required, and sintering times are reduced because bonding material can flow easily to near the surface. Elements with an internal lattice also offer advantages over hollow rolling elements. The shell can be thinner without sacrificing load capacity. The thinner shell reduces the time required for bonding material to be removed during sintering. The blank can be formed using various additive manufacturing processes.

Abstract: A hollow bearing rolling element or a rolling element with a lattice internal structure provides several advantages over a solid bearing. It is lighter than a solid bearing. Less material is required and sintering times are reduced because bonding material can flow easily to near the surface. The blank is formed using an additive manufacturing processes which offers better uniformity than a conventional two die process, enabling production of blanks much closer to finished size. They also eliminate the “Saturn Ring” associated with the conventional process. This translates into reduced grinding allowances and shorter processing time reducing both material and finishing operations costs. These processes also enable the production of hollow elements and partially hollow elements further reducing material costs, addressing the problems inherent to core material removal and reducing sintering time.
