Background
The double-intermediate-shaft transmission is a typical heavy-duty transmission, and is characterized by having two identical intermediate shafts compared with other heavy-duty transmissions, so that under the same working condition, the power distributed by each intermediate shaft is half of that of the single-intermediate-shaft transmission. The main shaft and the main shaft gear are in a floating state in the radial direction on the main shaft, and the main shaft and the input shaft adopt a floating structure in order to meet the requirements of correct meshing and the load distribution as even as possible. When the gearbox is in operation, the radial forces applied by the two intermediate shaft gears to the main shaft gears are equal in magnitude and opposite in direction and offset each other, so that the main shaft only bears torque and does not bear bending moment, the stress conditions of the main shaft and the bearing are improved, and the use reliability and durability of the gearbox are greatly improved.
