Problems solved by technology
[0004] This method has the following defects: the traction motor is positioned on the ground, and it is not convenient to adjust its position when assembling with the drive shaft system. The backlash adjustment between the driven gear and the driving gear can only be realized by adjusting the hoisting tool. The repeated adjustment of multiple parts can only be completed, the labor intensity is high, the work efficiency is low, and the safety factor of the operation in the ditch is low

The invention discloses an assembly table for a driving unit of a rail locomotive. The assembly table consists of a base, two roller support seats and a motor support seat arranged on the base; the roller support seats are provided with grooves, and the grooves are provided with two rollers , the roller has a main shaft extending outward; the motor support seat is connected with the adjustment support seat through the first lateral moving device, the adjustment support seat is connected with the lifting support seat through the second longitudinal moving device, and the lifting support seat is connected with the base through the lifting device . Put the installed wheelset of the drive shaft system on the two rollers in the groove through the spreader; fix the traction motor on the motor support seat, and adjust the traction motor through the lifting device, the first moving device and the second moving device. In the Z, X and Y directions, the backlash between the driving gear and the driven gear is detected by rotating the roller spindle with a wrench, and the assembly is completed on the assembly table; there is no need to repeatedly adjust the parts of the spreader, which is safe and reliable, reduces labor intensity, and improves assembly. Efficiency and assembly quality.
Description
technical field [0001] The invention relates to the technical field of installation, in particular to an assembly platform for a drive unit of a rail vehicle. Background technique [0002] The drive unit of a railway locomotive is composed of three parts: the drive shaft system, the traction motor and the gear cover. The drive shaft system is composed of three parts: the wheel set, the axle box and the axle box. The drive unit assembly here mainly refers to adjusting the backlash of the driving gear and the driven gear to complete the installation of the shaft holding box and the traction motor and the installation on the shaft holding box and the traction motor after the assembly of the driving shaft system is completed. The gear cover and the driving gear and the driven gear are placed in the gear cover. [0003] At present, the assembly of the drive unit of the railway locomotive is carried out directly on the ground. First, the traction motor is positioned on the ground...
