A planet carrier 100 has a member 110 which is resistant to buckling caused by torsional stress and which increases a torsional stiffness of the planet carrier 100, so that a torsion load is transmitted evenly from the input member 120 into planet pins 104 without twisting the planet carrier 100. The member 110 is a conical or frustoconical flange, rib or rim and extends from carrier legs 102 to form a kinematic structure comprising legs 108. A bearing arrangement may comprise double row tapered roller bearing (DRTB) located on a shaft on one side of the carrier 100 and adapted to react to tilting moments applied to the carrier 100. Reference is also made to a member which increases tortional stiffness of a planet carrier 100 so that a torsional load is transmitted evenly from an input member into planet pins 104 without twisting the planet carrier 100. The planet carrier may be incorporated into a gearbox for a wind turbine. |
