Power car wheel pair gear box side disk-braking press mounting technology

Abstract

The present invention provides a press mounting art of moving wheel to side brake disk of gear case; the semi-transition nylon is coated on the shaft body of the gear case which is preinstalled with a brake disk and then arranged and fastened on the rotary bracket, and the shaft center is adjusted to the same level with the center of the press machine; the position nylon with reticle is arranged and fastened on the shaft diameter; a transition device is arranged at the shaft end and then positioned at the shaft end with a position pin, one end of the line set rule is closed to the face of brake disk, while the other end is placed on the position nylon with reticle; when in the press mounting, the press machine supplies press to the ball press steel which then transmits the press to the transition press steel, the press finally reaches the shaft end; when the end face of line set rule is rightly engaged with the reticle on the position nylon, the press mounting procedure is completed. Under the condition of equal cost, the present invention applies the prior common wheel to fulfill the press mounting of the press machine, thereby assuring the efficiency of press mounting and the pass rate is 100 percent after press mounting.

Description

technical field [0001] The invention discloses a process for press-fitting a braking disc on the side of a gear box between a moving wheel and a gear box, and belongs to the technical field of tooling processes for mechanical components. Background technique [0002] In the locomotive production process, the brake discs are press-fitted next to the gear box of the moving wheels (see figure 2 ) is more difficult to realize. In the past, the press-fitting of the brake disc of the wheel set was based on the center of the axle shaft. Now, because the gear box has been assembled on the moving wheel set, the center of the axle can no longer be used as the benchmark for pressing the brake disc; One end of the axle at the gear box is prone to rollover during the press-fitting process of the brake disc due to the influence of gravity eccentricity; the shaft diameter deformation and the accident of pinching the shaft are prone to occur during the press-fitting process; because the bra...

Problems solved by technology

[0003] In order to solve the problem that the conventional press-fitting process cannot realize the press-fitting of the brake disc on the gear box side of the moving wheel, the invention discloses a press-fitting process of the brake disc on the gear box side of the moving wheel, without increasing the production cost, Use the existing ordinary wheel set press machine to complete the press assembly, which ensures the press assembly efficiency and ensures that the pass rate of press assembly is 100%.
