The invention relates to a radial piston hydraulic motor unit, which comprises a gib plate 12 for the radial piston hydraulic motor 10 in a fixed position, piston parts 15a1, 15a2 ... and rollers 16a1, 16a2 ... connected to these or corresponding parts being designed to move along the internal gibs 12a1, 12a2 ... of the gib plate, the rotor part, which acts as cylinder body in the piston parts, and a shaft 18 fixedly connected thereto being made to rotate by means of the pistons in the working position. The unit comprises a sun gear 28, which is driven by the shaft 18 and planetary gears 31a1, 31a2 in the support body 32 of the stationary planetary gears, which are made to rotate by the sun gear 28. The unit comprises a circumferential gear 34, which is driven by the planetary gears 31a1, 31a2..., the said circumferential gear being a part of the outer casing of the unit, which can be made to rotate. <IMAGE>
