| 摘要 |
A rolling element 100 for a bearing is at least partially constituted of a first printed material 105 being printed via an additive manufacturing process, such as direct laser deposition or stereo-lithography, selective laser sintering, selective laser melting, laminated object manufacturing, fused deposition modelling, selective binging, laser engineering net shaping, photo polymerization, selective electron beam sintering. The first printed material 105 comprises at least one channel 110, 120 open to an outer surface of the rolling element, the channel being configured and constructed to transport, in use, lubricant. The rolling element may comprise a hollow structure 130 containing a lubricant sponge 135 for supplying the outer surface of the rolling element with lubricant, in use. The rolling element may comprise a sensor (264, fig 2) and a controller (262, fig 2) for activating release of the lubricant. |
