| US11754117B2 — Rolling bearing with spring system (SKF, 2023) · metadata only · original: 460 US11754117B2 SKF Rolling Bearing Spring System Belleville TBM大直径主轴承预紧 | US patent 11,754,117 B2 to SKF (inventor Capoldi, granted September 2023). The bearing includes a first ring delimiting a radial rolling raceway and a spring system whose elements urge the rolling elements to cancel clearance; classification covers F16C 19/381. It protects elastic preload construction for large-diameter bearings in tunnel boring machines, with nine claims and three drawing sheets. | reference_pdf / applications-isolation | — | — | unknown / internal |
| US11313413B2 — Rolling bearing with spring biased thrust ring, and method for measuring an axial clearance (SKF, 2022) · metadata only · original: 461 US11313413B2 SKF Rolling Bearing Spring Biased Thrust Ring 轴向游隙测量 TBM轴承 | US patent 11,313,413 B2 to SKF (granted April 2022), covering a rolling bearing with a spring-biased thrust ring and a method for measuring axial clearance: a screw engages a threaded hole accessible from outside the first ring to compress the spring element and create a measurable gap, while operating clearance is cancelled by the spring systems. It serves assembly and inspection of large-diameter bearings in tunnel boring and mining machines, with sixteen claims. | reference_pdf / applications-isolation | — | — | unknown / internal |
| EP2851575B1 — Rolling bearing assembly with spring systems urging an elastic raceway ring (SKF, 2016) · original source · original: EP2851575B1 SKF Rolling Bearing Assembly Spring Washer Preload 大型轴承弹簧垫圈预紧消除轴向游隙 | SKF European patent EP2851575B1. For large bearings in tunnel boring machines, oil extraction installations and marine applications, the specification describes rollers cooperating with an elastic ring forming a raceway track, urged against the rollers by spring systems — spring washers — to cancel clearance, together with a manufacturing method. Patent basis for elastic preload design of TBM and large-diameter bearings. | reference_pdf / applications-isolation | — | — | reference_only / internal |
