Abstract

The present invention relates to a flywheel (100) comprising a plurality of discs (102) arranged in a stack (104), including at least first and second end discs at either end of the stack, each of the plurality of discs including a plurality of disc apertures therethrough, first and second plate members (106) disposed at opposing ends of the stack, one or both of the first and second plate members including a plurality of plate apertures therethrough for alignment with a corresponding series of disc apertures through the stack, and connection means for clamping the first and second plate members together about the stack of discs, in which one, some or all of the plurality of disc apertures includes circular disc apertures (120) for accommodating each of the connection means therethrough, and non-circular disc apertures (122a) spaced from a periphery (130) of each disc and slots (122b) extending from the periphery (130) of each disc for reducing stress at or around the circular apertures during flywheel rotation, the circular disc apertures being disposed between a pair of non-circular disc apertures and/or slots.

Abstract

A flywheel (100) comprising a plurality of discs (102) arranged in a stack (104), the plurality of discs including at least first and second end discs at either end of the stack and one or more discs between the first and second end discs, each disc including first and second opposing faces, each of the first and second opposing faces including a central region and a peripheral region disposed around the central region, the peripheral region being adjacent to a peripheral edge P of that disc, and bonding means for bonding together adjacent peripheral regions of neighbouring discs for flywheel rotation, in which one, some or all of the one or more discs includes: a first set of bonding areas (112) in the peripheral region of the first face, and one or more spacer areas (112a) in that peripheral region for spacing apart the bonding areas on the first face; a second set of bonding areas (114) in the peripheral region of the second face, and one or more spacer areas (114a) in that peripheral region for spacing apart the bonding areas on the second face; and at least one of: one or more of the bonding areas (112) at the first face is either disposed opposite a spacer area (114a) on the second face of that disc or disposed opposite both a portion of a spacer area (114a) and a portion of a bonding area (112) which are each on the second face of that disc; one or more of the bonding areas (114) at the second face is either disposed opposite a spacer area (114a) on the first face of that disc or disposed opposite both a portion of a spacer area (112a) and a portion of a bonding area (112) which are each on the first face of that disc.

Abstract

A flywheel (1000) comprising a plurality of discs (1002) arranged in a stack (1004), including at least first and second end discs at either end of the stack (1004), in which each disc (1002) includes a central region (1034) and a peripheral region (1032) disposed around the central region (1034), the peripheral region (1032) being adjacent to a peripheral edge of the disc (1002), first and second plate members (1006) disposed at opposing ends of the stack (1004), and bonding means (1030) which bonds only part of each disc (1002) to each neighbouring disc (1002) in the stack (1004), including bonding together adjacent peripheral regions (1032) of neighbouring discs (1002), and which bonds each of the first and second plate members (1006) respectively to the first and second end discs of the stack (1002).
