Epicyclic gear assembly planetary gear carrier

A planetary gear carrier assembly comprising:

• a plurality of planetary gears each rotatable about a respective planet axis defined by a respective pin through the gear;
• a planetary gear carrier having:
• a front face and a back face defining a housing therebetween, wherein at least a portion of the housing is an annular housing;
• and
• an annulus axis, wherein the plurality of planetary gears are located within and spaced circumferentially around the housing, the respective pin of each planetary gear passing from the front face to the back face at a location such that the planetary gear partially extends radially outwards of a periphery of the planetary gear carrier and
• a position balancing arrangement for at least one of the plurality of planetary gears, the position balancing arrangement comprising:
• a slot formed in the front face and back face, extending circumferentially to receive the respective pin of the at least one of the planetary gears for circumferential movement within the slot;
• a first resilient element in biased engagement with the respective pin to adjust a position of the respective pin in the slot towards a desired position responsive to movement of the respective pin away from the desired position in the slot, wherein the resilient element comprises a spring element configured to bias the pin to a central location within the slot;
• and
• a curved block at each end of the slot within which a respective spring element is secured.
