Compact geared reduction unit for application with transmission shaft subjected to radial loads

A compact geared reduction unit for application with transmission shaft subjected to radial loads, comprising:

• an accommodation body,
• a gear system accommodated inside said accommodation body,
• a driving shaft,
• a transmission shaft,
• an output reduction stage of the epicyclic type which comprises a driving sun gear which rotates about a main axis and a ring gear which is integrally associated with said accommodation body, between which multiple planet gears are engaged which are supported in rotation about respective longitudinal axes which are parallel to said main axis by a transmission planet carrier, which in turn rotates about said main axis and is connected so as to be integral in rotation with said transmission shaft at a connection region, such that rotary motion is transmitted from said driving shaft to said transmission shaft, and
• rolling means comprising a first radial bearing which is arranged interposed in a radial direction between said accommodation body and said planet carrier and a second radial bearing which is arranged radially between said accommodation body and said transmission shaft, the first and second radial bearings being arranged axially on opposite sides of said connection region such that said rolling means being adapted to support radial loads subjected to said transmission shaft for the rotational guiding of said transmission shaft.
