Cooling ring bracket

Abstract

The invention relates to a cooling ring bracket, and describes a bracket (1) for securing a number of cooling rings (R1, R2, R3) arranged on a bearing ring (30), which bracket (1) comprises an upper surface (11), a lower surface (10) shaped to lie on the cooling rings (R1, R2, R3), and a through-opening (14) extending between the upper surface (11) and the lower surface (10) to accommodate a fastener (4) for mounting the bracket (1) to the bearing ring (30); wherein the material properties of the bracket (1) are chosen to permit movement of the cooling rings (R1, R2, R3) relative to the bracket (1) when the bracket (1) is mounted to the bearing ring (30); and / or wherein the bracket (1) is made of a resilient elastic material. The invention further describes a cooling arrangement (2) for abearing (3), comprising a number of cooling rings (R1, R2, R3) arranged in parallel on a mounting surface (30S) of a bearing ring (30) of the bearing (3); and a number of such brackets (1) to secure the cooling rings to the bearing body (30).

Description

technical field [0001] The present invention describes cooling ring supports and cooling arrangements. Background technique [0002] Large bearings are necessary in various applications such as large electric motors. Main bearings of generators such as multi-megawatt wind turbine generators may have a diameter of several meters. During operation, the rotating bearing ring turns relative to the stationary bearing ring, and it is often unavoidable to generate heat during operation, so large bearings require some kind of cooling arrangement. [0003] One way of cooling such a large bearing is to arrange a number of hollow annular passages or "cooling rings" around the stationary bearing ring and to feed a fluid cooling medium through these passages. The cooling circuit is completed by connecting the cooling ring by means of hoses to a pump which circulates a fluid coolant through the channels. Thermal paste can be applied between the bearing surface and the cooling ring to i...

AI Technical Summary

Problems solved by technology

As mentioned above, the hose is attached to the cooling ring at one point in order to circulate the fluid coolant, but the creeping movement of the cooling ring can eventually lead to failure at the hose connection point

A cold weld is more likely to form between two objects made of the same metal, but even if the bracket is made of a metal different from that of the cooling ring to avoid the formation of a cold weld, this will not solve the problem of loose fasteners The problem
