Gear box, has inner slat carrier whose peripheral groove is coupled with radial internal cavity over radial bore to supply cooling oil from peripheral groove to radial internal cavity and over another radial bore for refrigeration

摘要

The box (1) has a pump shaft (19) defining a radial internal cavity (20), where pressurized oil for actuation of disk clutch (4) is fed into the internal cavity. An output-side shaft (3) comprises a radial bore (24), where cooling oil from a radial outer cavity (23) is supplied through the bore into a peripheral groove (26) of an inner slat carrier (15). The groove is coupled with the internal cavity over a radial bore (27) of the slat carrier to supply the cooling oil from the groove to the internal cavity and over another radial bore (29) of the slat carrier for refrigeration.
