A bearing arrangement for harmonic or strain wave gearing, wherein the bearing arrangement comprises a mating gear, a wave generator, and gearing between the mating gear and the wave generator. The flexible gearing comprises gear teeth which are engaged with corresponding gear teeth on the mating gear. A plurality of rollers is disposed between the flexible gearing and the wave generator. The rollers may be engaged by a roller cage which is also disposed between the flexible gearing and the wave generator, thereby preventing the rollers from contacting each other and preventing roller-to-roller friction. The rollers ride directly on the exterior surface of the wave generator. As the wave generator moves, the wave generator pushes on the rollers which, in turn, push on the flexible gearing. The flexible gearing, in turn, meshes with the mating gear, thus creating relative motion. The bearing arrangement is such that the rollers roll directly on the flexible gearing and the wave generator, and the rollers experience relative motion between themselves and the wave generator as well as the flexible gearing.

A roller bearing sub-assembly can include a first mounting portion, a second mounting portion spaced apart from the first mounting portion, a first roller disposed between the first and second mounting portions and straps wrapped partially around different portions of the first roller. The first mounting portion, second mounting portion, first roller and straps are configured such that the first and second mounting portions are moveable relative to each other along a selected direction for a distance that is approximately equal to a circumference of the first roller in opposite directions from a mid-stroke position. Linear roller bearing assemblies and methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.

A roller bearing includes an outer ring having a substantially cylindrical internal bearing surface and an outside surface defining a plurality of protuberances. A protective coating is applied to the outside surface of the outer ring. An inner ring is coaxially disposed at least partially in the outer ring and has a substantially cylindrical external bearing surface. The external bearing surface and the internal bearing surface define an annular cavity in which a plurality of rolling elements is disposed. The rolling elements are in rolling engagement with the external bearing surface and the internal bearing surface. The outside surface of the outer ring can be case hardened, for example the outer ring can be carburized. The outside surface of the outer ring can be knurled. A method of manufacturing such a bearing is also disclosed.

Linear roller bearing assemblies can include a hub, a collar around the hub and roller bearing sub-assemblies disposed in a radial pattern around the hub. The roller bearing sub-assemblies can guide linear movement of the hub relative to the collar along a selected direction. Each roller bearing sub-assembly can include a roller and straps wrapped partially around the roller. Each strap is connected to at least one of the hub and the collar. And at least one of the straps can be connected to the roller while at least one of the straps can be circumferentially free of the roller. The hub and collar are moveable relative to each other along the selected direction for a distance that is approximately half of a circumference of the roller. Methods of forming linear roller bearing assemblies are also disclosed, as are multi-cylinder Stirling engines and a thermal energy recovery system.

Screw thread holes 20 circumferentially spaced from each other are formed in a first ring 10, and through holes 21 circumferentially spaced from each other are formed in a second ring 11. A screw thread section 40 and a press fitting section 42 are formed on the outer periphery of each pin 13. The minimum inner diameter of the through holes 21 in the second ring 11 is set greater than the maximum outer diameter of a portion of the pin 13 which is positioned closer to the screw thread section 40 than the press fitting section 42. The screw thread sections 40 of the pins 13 are screwed into the screw thread holes 20 in the first ring 10, and the press fitting sections 42 of the pins 13 are fixed in the through holes 21 in the second ring 11 by interference fit.
