1. An oil collecting bushing for a bearing arranged for guiding lubricating oil into a roller path of the bearing, the oil collecting bushing having an axial direction, a radial direction and a circumferential direction and comprising:
a cylindrical bushing main body, wherein an oil collecting groove for collecting the lubricating oil is formed on an inner circumferential part of the bushing main body, and the bushing main body is provided with a plurality of openings which penetrate the bushing main body and which are in communication with the oil collecting groove; and
a plurality of oil claws arranged at parts of the bushing main body where the openings are formed, wherein each oil claw is formed so as to warp radially outwards from the bushing main body, therefore, under a centrifugal force generated during rotation of the oil collecting bushing, the lubricating oil from the oil collecting groove is guided into the roller path by the corresponding oil claws via the openings.
 
8. A transmission, comprising:
a bearing; and
an oil collecting bushing arranged for guiding lubricating oil into a roller path of the bearing, the oil collecting bushing having an axial direction, a radial direction and a circumferential direction and comprising:
a cylindrical bushing main body, wherein an oil collecting groove for collecting the lubricating oil is formed on an inner circumferential part of the bushing main body, and the bushing main body is provided with a plurality of openings which penetrate the bushing main body and which are in communication with the oil collecting groove; and
a plurality of oil claws arranged at parts of the bushing main body where the openings are formed, wherein each oil claw is formed so as to warp radially outwards from the bushing main body, therefore, under centrifugal force generated during rotation of the oil collecting bushing, the lubricating oil from the oil collecting groove is guided into the roller path by the corresponding oil claws via the openings.
