PCT No. PCT/SE90/00201 Sec. 371 Date Nov. 28, 1990 Sec. 102(e) Date Nov. 28, 1990 PCT Filed Mar. 29, 1990 PCT Pub. No. WO90/12215 PCT Pub. Date Oct. 18, 1990.A device for mounting a machine element, such as a shaft (9). According to a first aspect of the invention, a bearing housing (5) is mounted on a machine body (1) by means of a plate-shaped supporting means (22) having a main plane perpendicular to the shaft (9). The supporting means (22) is rigidly connected with both the machine body (1) at first points of attachment (23), and with the bearing housing (5) at second points of attachment (24) which, in the main plane, are separate from the first points of attachment (23). The supporting means (22) has a rigidity in its main plane and a corresponding flexibility across its main plane, so as to be capable of transmitting substantially radial load and so as to permit, by deflection between the first and the second points of attachment (23, 24), a movement of the bearing housing (5) in relation to the machine body (1). The invention also relates to a structure for transmitting axial bearing load, which comprises an annular retainer (30) which is centered with respect to the shaft (9) and has two pairs of diametrically opposed recesses (31, 32), said pairs being at an angle of 90 DEG to one another. The recesses (31) in the first pair and the recesses (32) in the second pair are open in opposing axial directions. Four rolling elements (34, 35) are loosely received in the recesses (31, 32). The rolling elements (34) in the first pair have rolling contact with and form a first axis of rotation relative to the machine body (1), and the rolling elements (35) in the second pair have rolling contact with and form a second axis of rotation relative to a bearing housing associated with the structure at issue. |
