Live ring

摘要

To accept axial and radial loads use is made of at least two rows of rolling elements which roll on tracks of at least one inner race and at least one outer race. To check the tracks and rolling elements in the installed state, at least one row of rolling elements is covered by a removable guide ring accessible from outside or inside, and at least one inner or outer race which can be at least partially removed in the unloaded state or a race part is provided. Live rings of this kind are used in heavy lifting, conveying and transshipping equipment such as bucket wheel excavators, cranes used in transshipment and offshore, in oil buoys and towers for casting ladles, to connect the rotatable upper part to the fixed lower part.
