Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as Figure 1-2 As shown, a right axle box of a railway rail car according to the present invention includes a bearing hole 1, a first trapezoidal groove 2, a first pin hole 3, a first spring hole 4, an upper vertical plate 5, and an inner opening gear Surface 6, tie rod locking hole 7, first drain hole 8, second trapezoidal groove 9, second pin hole 10, threaded hole 11, second spring hole 12, second drain hole 13, axle box support plate 14.

[0015] Bearing hole 1 is the main center part of the product, connecting the upper and lower mounting parts and the right and right mounting parts. Bearing hole 1 is processed by boring, and six rings are evenly distributed on the outside of bearing hole 1 and processed by drilling chips. The purpose of the threaded hole 11 is to improve the installation accuracy and installation st...

Abstract

A right axle box of a railway rail car, including bearing holes, bolt holes, v-shaped grooves, pin holes, spring holes, upper vertical plates, inner openings, pull rod locking holes, drainage holes, threaded holes, and axle box supports plate. The product assembly blank is made by casting integral molding process. The main installation part of the product composed of the bearing hole, the v-shaped groove and the spring hole is connected with the wheel set and the frame of the vehicle. The structure design of the axle box body of the present invention is simple and reasonable. It changes the original integrated structure made of ductile iron material into an integrated structure made of carbon steel material for railway rail vehicles, which not only improves the overall mechanics of the axle box body performance, and make the manufacturability of the axle box better, reduce the processing difficulty of the axle box and the overall weight of the axle box, and at the same time, the surface finish of the processed product is high, which can effectively meet the customer's requirements for product appearance quality.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a right axle box body of a railway rail car. Background technique [0002] The railway track axle box is an important part of the heavy railway rail car. This part connects the wheel set and the bogie frame. Because the vehicle is overloaded during actual use, deformation and cracks will also occur. The quality of this part has a great impact on the whole It has an important influence on the safety and stability of the vehicle. Moreover, traditional products have problems such as backward structural design and low technological level. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the problems of weak mechanical properties, low strength, poor manufacturability, high processing difficulty, high cost, heavy product weight and insufficient assembly of the existing axle box. The design proposes a simple ...
