Abstract
The bearing device has a support ring positioned around a rotating shaft and a plurality of bearing pads provided between the rotating shaft and the support ring and configured to support the rotating shaft. Some of the plurality of bearing pads are positioned at a lower side of the rotating shaft, and a key member is installed between the support ring and a carrier ring supporting the plurality of bearing pads. The key member is inserted therebetween in a tangential direction of an outer circumference of the carrier ring and is configured to perform positioning of the plurality of bearing pads and the support ring in a radial direction.
Claims8
A bearing device comprising:
- a support ring positioned around a rotating shaft;
- a plurality of bearing pads provided between the rotating shaft and the support ring and configured to support the rotating shaft;
- a carrier ring supporting the plurality of bearing pads;
- and
- a key member installed between the support ring and the carrier ring to perform positioning of the plurality of bearing pads in a radial direction of the rotating shaft with respect to the support ring, wherein
- some of the plurality of bearing pads are positioned at a lower side of the rotating shaft,
- an inner circumference surface of the support ring includes a flat support surface that is inclined with respect to a base plane and supports the carrier ring from below,
- the flat support surface of the support ring has a key groove with an opening that faces obliquely upward, the key member being removably insertable into the key groove along a bottom face of the key groove, and
- the key member is installed to the key groove by inserting the key member to the key groove in a tangential direction of an outer circumference of the carrier ring via the opening.
