Abstract
A shoe bearing for a heavy rotary drum such as a cylindrical casing of a tube mill designed so that all the shoe bearing elements used at each bearing station are always uniformly loaded. One of the two outlying shoe bearing elements (11) is braced directly against the foundation (16) while the other shoe bearing elements (12, 13, 14) of the bearing station are supported on a flexible support cable (17).
Claims8
A shoe bearing for supporting the lower circumferential region of a cylindrical casing (10) of a tube mill on a foundation (16), comprising:
- a plurality of bearing stations spaced from one another in the axial direction of said cylindrical casing (10), each of said bearing stations including
- a fixed bearing block (15) on said foundation (16);
- a supporting cable (17) having one end anchored on said bearing block (15);
- shoe bearing elements (11, 12, 13, 14) spaced circumferentially from one another about said lower circumferential region of said cylindrical casing (10) including a pair of circumferentially outermost shoe bearing elements (11, 14) and at least two intermediate shoe bearing elements (12, 13) disposed circumferentially between said outermost shoe bearing elements (11, 14);
- one of said outermost shoe bearing elements (11, 14) being supported directly on said foundation (16);
- said intermediate shoe bearing elements (12, 13) and the other one of said outermost shoe bearing elements (11, 14) being secured to said supporting cable (17);
- said outermost shoe bearing elements each include a bearing shell supporting said cylindrical casing (10), a lower supporting part and a spherical cap (19, 20) between said bearing shell and said lower supporting part and
- a tension device mounted on said foundation (16) and connected to the other end (18) of said supporting cable (17), said tension device being operable to adjust the tension of said supporting cable (17).
