Sliding type ventilating duct for locomotive traction motor

Abstract

The invention discloses a sliding type ventilating duct for a locomotive traction motor, comprising a wearing plate, an upper bending plate, a rubber air duct body, an upper securing plate, a lower securing plate and a round spring, wherein the upper bending plate is arranged below the wearing plate; the upper securing plate is arranged below the upper bending plate; the rubber air duct body is of waveform; the upper end and the lower end of the rubber air duct body are respectively and fixedly together with the upper securing plate and the lower securing plate; the wearing plate, the upper bending plate and the rubber air duct body are fixed through bolts; the round spring is arranged in the rubber air duct body; and the elastic deformation direction of the round spring is consistent with the waveform deformation direction of the rubber air duct body. The sliding type ventilating duct for the locomotive traction motor, provided by the invention, is compact in whole structure, small in occupied space, attractive and order in whole as well as smaller in wind resistance and easier to meet the requirement of ventilation quantity of the traction motor due to the adoption of a short air duct; and when a locomotive passes by a small curve, the reliability of the air duct is improved, the rotating requirement of a steering frame and a frame is met, and the requirement for the ventilation quantity of the traction motor is ensured.

Description

technical field [0001] The invention relates to an air duct, in particular to a sliding air duct for a traction motor of a locomotive, and belongs to the technical field of motor air ducts. Background technique [0002] The rapid development of modern high-speed railways has put forward higher and higher requirements for locomotives. High-speed and heavy-duty locomotives require large traction motor power and high heat dissipation requirements for the unit. The heat dissipation of the unit will determine whether the locomotive can run safely. Therefore , the requirements for the locomotive traction motor and its supporting air passage are also higher. [0003] The traditional locomotive traction motor air duct adopts a soft air duct, which is made of five-proof cloth. Generally speaking, the soft air duct made of polyethylene grease PB five-proof cloth material cannot be stretched and contracted, and the supporting steel wire and fabric in the soft air duct are folded and s...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a sliding air duct for locomotive traction motors, which solves the technical problems that the existing air ducts made of five-proof cloth and rubber are easy to be damaged, and are bloated and inflexible when used, so as to effectively Solve the problems existing in the above-mentioned prior art
