摘要： A compact geared reduction unit for application with transmission shaft subjected to radial loads, comprising a box-like body inside which a gear system is accommodated for the transmission of rotary motion from a driving shaft to a transmission shaft, which is provided with an output reduction stage of the epicyclic type; the output reduction stage comprises a driving sun gear which rotates about a main axis and a ring gear which is integrally associated with the box-like body, between which multiple planet gears are engaged which are supported in rotation about respective longitudinal axes which are parallel to the main axis by a transmission planet carrier, which in turn rotates about the main axis and is associated so as to be integral in rotation with the transmission shaft at a connection region. The reduction unit furthermore provides for rolling means adapted to support radial loads associated with the transmission shaft.

摘要： A device for mutual retention and disengagement between a shaft and a hub of an articulation fork is provided. The device includes a sleeve that is fitted slidingly on the hub and a spring that is also fitted on the hub. The hub includes at least one radial seat that accommodates a respective locking ball, which can move along the radial seat to exert a force for retaining the shaft in the hub. The sleeve can slide, in contrast to the axial thrust force exerted by the spring on the sleeve, from a configuration for retention of the shaft, in which the annular collar prevents the radial outward movement of the locking ball in order to exert the force for retention of the shaft in the hub, to a disengagement configuration.
