Mechanical assembly with two transmission boxes of bevel gears, in particular intended to drive an agricultural machine.

摘要

The invention relates to a mechanical assembly of two packs of transmission of bevel gears 9, 10, in particular for driving an agricultural machine for the power takeoff shaft of a tractor. The assembly further comprises a pivot bearing it providing a connection to the pivoting movement between the two return transmission. In order to improve the bearing assembly of the two packs of transmission of the wheel relative to each other, the two casings 22, 23 of the dishes of transmission are provided with sleeves of the bearing 24, 25, which in the mounted state, penetrates into the interior space 34 a of the casings. This makes it possible to reduce the - axes of the two shaft ends of the coupling 13, 16 which are associated with the bevel gears 41, 44, which gearing with the conical wheels 49, 57 disposed on the connecting shaft 67. One thus obtains a better absorption of forces.
