Bearing whose load supporting position can be changed
A bearing of which a load supporting position capable of being changed, including: a cylindrical housing comprising a hollow inner circumferential surface; one or more support members provided in the housing and disposed along a circumferential direction of the inner circumferential surface; a plurality of pin holes provided along an outer circumferential surface of the housing; and a rotation preventing pin coupled to a first pin hole of the plurality of pin holes and configured to prevent rotation of the housing. In addition, threads are formed on inner circumferential surfaces of the pin holes and an outer circumferential surface of the rotation preventing pin to enable a pin hole and the rotation preventing pin to be easily coupled and decoupled.
1. A bearing of which a load supporting position is capable of being changed, the bearing comprising:
a cylindrical housing comprising a hollow inner circumferential surface;
one or more support members provided in the housing and disposed along a circumferential direction of the inner circumferential surface;
a plurality of pin holes provided along an outer circumferential surface of the housing;
a rotation preventing pin coupled to a first pin hole of the plurality of pin holes and configured to prevent rotation of the housing;
the hollow inner circumferential surface and the outer circumferential surface are concentric;
an inner circumferential surface of each of the plurality of pin holes comprises hole threads;
an outer surface of the rotation preventing pin comprises pin threads corresponding to the hole threads so that the rotation preventing pin can be coupled to the first pin hole of the plurality of pin holes; and
a portion of the outer surface of the rotation preventing pin that is configured to engage with a fixing member is unthreaded.
2. The bearing of claim 1 , wherein an inner circumferential surface of each of the plurality of pin holes comprises hole threads.
3. The bearing of claim 2 , wherein an outer surface of the rotation preventing pin comprises pin threads corresponding to the hole threads so that the rotation preventing pin can be coupled to the first pin hole of the plurality of pin holes.
4. The bearing of claim 1 , wherein the rotation preventing pin is configured to be removed from the first pin hole of the plurality of pin holes and then coupled to a second pin hole of the plurality of pin holes such as to change the load supporting position.
5. The bearing of claim 1 , wherein the plurality of pin holes are formed at a constant interval.
6. The bearing of claim 1 , wherein the one or more support members comprise tilting pads.
7. A bearing capable of changing a load supporting position, the bearing comprising:
a housing comprising:
an inner circumferential surface configured to support a shaft; and
an outer circumferential surface;
one or more support members provided on the inner circumferential surface;
a plurality of pin holes provided along the outer circumferential surface of the housing;
a rotation preventing pin coupled to a first pin hole of the plurality of pin holes and configured to prevent rotation of the housing by protruding from the housing and engaging with a fixing member,
the inner circumferential surface and the outer circumferential surface are concentric;
an inner surface of each of the plurality of pin holes comprises hole threads;
an outer surface of the rotation preventing pin comprises pin threads corresponding to the hole threads so that the rotation preventing pin can be coupled to the first pin hole of the plurality of pin holes; and
a portion of the outer surface of the rotation preventing pin that is configured to engage with the fixing member is unthreaded.
8. The bearing of claim 7 , wherein an inner surface of each of the plurality of pin holes comprises hole threads.
9. The bearing of claim 8 , wherein an outer surface of the rotation preventing pin comprises pin threads corresponding to the hole threads so that the rotation preventing pin can be coupled to the first pin hole of the plurality of pin holes.
10. The bearing of claim 7 , wherein the rotation preventing pin is configured to be removed from the first pin hole of the plurality of pin holes and then coupled to a second pin hole of the plurality of pin holes such as to change the load supporting position.
11. The bearing of claim 7 , wherein the plurality of pin holes are formed at a constant interval.
12. The bearing of claim 7 , wherein the one or more support members comprise tilting pads.
