A thrust bearing for a wind turbine comprising: a thrust collar rotatable around a longitudinal axis of the thrust bearing and having a thrust surface transversally oriented with respect to longitudinal axis, a support structure fixed with respect to the longitudinal axis of the thrust bearing, a bearing pad contacting the thrust surface of the thrust collar and movable on a pad seat provided in the support structure, the pad seat comprising a first portion adjacent to the thrust collar and a second portion longitudinally adjacent to the first portion, the first portion having a first radial extension and the second portion having a second radial extension greater than the first radial extension, the first radial extension and the second radial extension being transversally oriented with respect to the longitudinal axis, the bearing pad comprising a first portion coupled with the first portion of the pad seat, a second portion coupled with the second portion of the pad seat and a shoulder formed between the first portion and the second portion of the pad seat preventing the bearing pad from exiting the pad seat in the longitudinal direction towards the thrust collar, a thrust plate fixed to the support structure, opposite to the bearing pad, wherein at least a spring element is interposed between the bearing pad and the thrust plate, characterized by the bearing pad comprising a male element and a female element coupled to one another with backlash, the male element being inserted in a pocket of the female element allowing relative tilting between the male element and the female element about an axis orthogonal to the longitudinal axis. a thrust collar rotatable around a longitudinal axis of the thrust bearing and having a thrust surface transversally oriented with respect to longitudinal axis, a support structure fixed with respect to the longitudinal axis of the thrust bearing, a bearing pad contacting the thrust surface of the thrust collar and movable on a pad seat provided in the support structure, the pad seat comprising a first portion adjacent to the thrust collar and a second portion longitudinally adjacent to the first portion, the first portion having a first radial extension and the second portion having a second radial extension greater than the first radial extension, the first radial extension and the second radial extension being transversally oriented with respect to the longitudinal axis, the bearing pad comprising a first portion coupled with the first portion of the pad seat, a second portion coupled with the second portion of the pad seat and a shoulder formed between the first portion and the second portion of the pad seat preventing the bearing pad from exiting the pad seat in the longitudinal direction towards the thrust collar, a thrust plate fixed to the support structure, opposite to the bearing pad, wherein at least a spring element is interposed between the bearing pad and the thrust plate, characterized by the bearing pad comprising a male element and a female element coupled to one another with backlash, the male element being inserted in a pocket of the female element allowing relative tilting between the male element and the female element about an axis orthogonal to the longitudinal axis.
