Axle gear box applied to internal combustion locomotive

Abstract

The invention discloses an axle gear box applied to an internal combustion locomotive. The axle gear box comprises a box body; the box body comprises a left box body and a right box body, wherein the left box body is connected with the right box body through a bolt, and the sections of the left and right box bodies are circular; the interior of the left box body and the interior of the right box body are in smooth curved surface are smooth curved surfaces in smooth transition; the right box body is provided with an observation cover and a ventilating cap; a pulling arm seat connected with the locomotive is arranged outside the right box body; an input shaft is arranged on the right box body; an axle in orthogonal transmission with the input shaft penetrates into the left box body and the right box body; a pair of wheels are arranged on the axle; the two ends of the axle are each provided with an axle box body; the axis of the input shaft and the axis of the axle are positioned in the same plane, and orthogonal transmission of the input shaft and the axle is realized by virtue of a pair of a Gleason spiral bevel gear pair; an oil arranging part for arranging lubricating oil is arranged inside the right box body; the Gleason spiral bevel gear pair is in contact with the oil arranging part. The axle gear box applied to the internal combustion locomotive has the characteristics of being compact in structure, small in size, high in reliability, capable of playing a relatively strong effect on control of gear noise radiation and the like.

Description

technical field [0001] The invention relates to an axle gearbox, in particular to an axle gearbox for a diesel locomotive. Background technique [0002] Diesel locomotives are mainly used for the transportation of soil and rock debris in tunnel engineering construction. At present, the axle gearboxes used for traditional internal combustion locomotives cannot meet the needs of tunnel engineering construction companies due to their high requirements for compactness, volume, reliability, and formal structure. High requirements for the use of shaft gearboxes; the harmful deformation and noise radiation caused by the temperature gradient in the box during the transition process and steady-state operation will affect the reliability of its work; therefore, it involves a compact structure, volume Small and reliable axle gearboxes for diesel locomotives are of great importance. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the a...
