Sectioning circular ring casing and alloy wheel hub combined energy storage flywheel

Abstract

The invention provides a sectioning circular ring casing and alloy wheel hub combined energy storage flywheel. The flywheel comprises a mandrel, a wheel hub and a wheel rim which are arranged coaxially from inside to outside; the wheel hub comprises a sectioning circular ring casing, a circular ring plate and a cylindrical casing; the circular ring plate is fixedly connected with the cylindrical casing via a hole, corresponding to the cylindrical casing, arranged in the center of the circular ring plate; the circular ring plate is fixedly connected with the sectioning circular ring casing viaan edge, corresponding to the sectioning circular ring casing, formed by segmentation in the periphery of the circular ring plate; and the sectioning circular ring casing is an incomplete circular ring casing formed by segmenting a hollow cylinder concretely. The sectioning circular ring casing matches the circular ring plate in the wheel hub, so that during rotation of the combined energy storageflywheel, the sectioning circular ring casing can be opened outwardly automatically and clings to the inner side of the wheel rim due to that the circular ring casing is the incomplete casing by segmentation, the wheel hub and the wheel edge are cooperated tightly and do not separate from each other during high-speed rotation, gross distortion coordination of the wheel hub and the wheel rim is realized, and the intensity safety under gross distortion coordination is ensured.

Description

technical field [0001] The invention relates to the technical field of generator detection, in particular to a combined energy-storage flywheel with a split ring shell alloy hub. Background technique [0002] Flywheel energy storage is an advanced physical energy storage technology with high power density, rapid response, long life, and friendly environmental characteristics. In order to improve the energy storage density and power density, the flywheel usually runs at a very high speed (more than 10000rpm), and there is a strong stress caused by high-speed centrifugal load inside the flywheel structure. In order to prevent the stress from exceeding the strength of the material, high-strength, low-density materials must be used. For advanced materials, such as wound fiber reinforced composites, due to the anisotropy of wound fiber composites, the stress state and allowable strength in both hoop and radial directions need to be considered. [0003] The radial stress of the f...
