Abstract: A gear pair for a lifting vessel includes two gear units driving in opposite directions of rotation and configured for engagement in two tooth racks on a jack-up leg, respectively. Each gear unit includes a drive shaft for connection to a drive, an output shaft for connection to a drive pinion, a transmission housing, a planetary stage mounted in the transmission housing, and a torque support configured to enable support of the gear unit on the other gear unit. The torque support surrounds the transmission housing of the other gear unit in a pincer-like manner and contacts the transmission housing symmetrically with respect to a straight line connecting the output shafts of the gear units at two support points which in relation to a vertical plane extending through the output shaft of the other gear unit are located offset towards the gear unit having the torque support.

Abstract: A device for translationally maneuvering a structure able to move with respect to a fixed support, includes at least one rack and at least one output pinion which is driven by motor elements via a gear train borne by a chassis. At least one element of the gear train consists in a slave element borne by a shaft equipped with torque limiting elements collaborating with the chassis and having a limit torque which is determined so as to: immobilize the slave element in terms of rotation with respect to the chassis when its torque is below the limit torque to permit translational maneuvering of the mobile structure by the turning of the output pinion; and allow the slave element to rotate with respect to the chassis when its torque is higher than the limit torque, to avoid a static or dynamic overload being applied to the gear train.
