Railway locomotive and gear box and axel-hung box coupling device thereof

Abstract

The invention provides a railway locomotive and a gear box and axel-hung box coupling device thereof. The coupling device comprises a gear box and an axel-hung box, wherein a rubber coupler is fixed to the gear box; the rubber coupler comprises an outer body, a rubber pad and an inner shaft sleeve, wherein a central hole is reserved on the outer body; the inner shaft sleeve penetrates through the central hole; the rubber pad is arranged between the outer wall of the inner shaft sleeve and the inner wall of the central hole; a positioning card is arranged between the axel-hung box and the rubber coupler; a positioning hole and a positioning edge are reserved on the positioning card; the positioning hole is opposite to the shaft hole of the inner shaft sleeve; the outer wall of the outer body of the rubber coupler is locked by the positioning edge; and a coupling bolt penetrates through a first bolt hole on the axel-hung box, the positioning hole on the positioning card and the shaft hole in the inner shaft sleeve of the rubber coupler for coupling and fixing the axel-hung box and the gear box. The railway locomotive prevents the gear box from generating structure crackles to cause oil leakage.

Description

technical field [0001] The invention relates to the connection technology of railway locomotive parts, in particular to a railway locomotive and its gear box and shaft holding box coupling device. Background technique [0002] In the axle-suspended locomotives of the prior art, the motor can be elastically suspended on the locomotive frame, and the output power of the motor can be transmitted to the wheelset through the coupling device of the gearbox and the axle box. Specifically, such as figure 1 as shown, figure 1 It is a structural schematic diagram of the prior art gearbox and shaft holding box coupling device, which may include a gearbox 11 and a shaft holding box 12, wherein the gearbox 11 is installed between the motor and the shaft holding box, one end of which is connected to the motor, and the other end The axle holding box 12 is rigidly connected through the mounting base 29; the axle holding box 12 is arranged on the axle, and the output power of the motor can...
