The utility model discloses a differential mounting and connecting structure and engineering machinery. The differential mounting and connecting structure comprises a differential shell, a differential shell cover, an assembled cross shaft, a bevel gear and a pair of half shaft gears, the differential shell and the differential shell cover are connected together through a fastener; the assembled cross shaft is arranged in the differential shell; four bevel gears are respectively mounted at four end parts of the cross shaft; a pair of half axle gears are respectively arranged on the differential shell and the differential shell cover; and the half axle gears are meshed with the bevel gear. The cross shaft composed of the straight shaft, the two short shafts and the cross shaft sleeve can transmit larger torque, the service life of the shaft is prolonged, the bearing capacity of the shaft is improved, compared with a traditional cross shaft, the cost of the cross shaft formed by the structure is greatly reduced
