    摘要: A drive shaft system (100) comprising a shaft (80) connected to a motor via a coupling (50) and arranged to transmit a rotary movement from the motor to the rotor, at least two supports (65,75) arranged to position the shaft within a shaft housing (90), each support comprising at least one bearing (95,98), and at least one forcing element (135,145) arranged to force at least one of the supports against either an inner side of the shaft housing or an outer side of the shaft (80); such as to prevent turning and radial movements of the supports within the shaft housing while enabling axial movement of the shaft within the shaft housing. The bearings may be forced at either their inner or outer rings, and may be enclosed in a bearing housing (120) for protection and stiffness.

    摘要: A bearing cartridge for a rotatable shaft of a wind turbine comprising a shaft and a back-to-back tapered roller bearing arrangement coupled to the shaft. The bearing arrangement comprising a first bearing having a first outer ring, a first inner ring and a plurality of tapered rollers; and a second bearing having a second outer ring, a second inner ring and a plurality of tapered rollers. The bearing cartridge further comprising a gear located on the shaft between the first bearing and second bearing and a sleeve for supporting an axial load between the first and second bearings and having one or more apertures that expose the gear for coupling to an external gear.
