The invention discloses a rail vehicle wheel set automatic compensation pressing method of the present invention. First, measure and record the measured diameter D of the wheel tread, and lift the wheel to the wheel bracket, hoist the axle to the axle bracket, and the wheel support Both the bracket and the axle bracket can move up and down. The two move up and down and cooperate with each other to adjust the actual distance between the wheel tread and the axle axis. After adjustment, the wheel is pre-installed on the axle, and then the press is started to press the wheel. onto the axle. The rail vehicle wheel set automatic compensation press-fitting method of the present invention can avoid the problem of unstable press-fitting quality caused by temperature changes, better ensure the success rate of press-fitting, and simultaneously improve the press-fitting work efficiency.
Description
technical field [0001] The invention relates to the technical field of rail vehicle equipment and its surrounding supporting facilities, in particular to an automatic compensation press-fitting method for rail vehicle wheel sets. Background technique [0002] The wheel set is the part of the rolling stock that is in contact with the rail, and consists of two left and right wheels firmly pressed on the same axle. The role of the wheel set is to ensure the running and turning of the rolling stock on the rails, bear all the static and dynamic loads from the rolling stock, transmit it to the rail, and transfer the load caused by the uneven track to the parts of the rolling stock. In addition, the driving and braking of the rolling stock also work through the wheel set. Therefore, there are strict requirements on the assembly pressure and press-fitting process of the axle and wheel to ensure the smooth operation of the rolling stock. [0003] The conventional wheel set press-fit...
