Abstract
A kind of railway locomotive left axle casing, including bearing hole, V-shaped groove, pin shaft hole, spring eye, right reinforcement, upper vertical plate, internal arm face, Draw bar lock tieholen, osculum, screwed hole, left reinforcement.The product assembly blank is made up of casting integrated moulding process.The bearing hole, V-shaped groove, the main mounting portion of spring eye composition product are connected with car wheel-set and vehicle frame.Axle box structure design of the present invention is simple, reasonable, it is by integrative-structure made of original ductile cast iron material, make the integrative-structure made of railroad track vehicle carbon steel material into, not only increase the overall mechanical properties of axle box, and make the manufacturability of axle box more preferable, the difficulty of processing of axle box and the weight that axle box is overall are reduced, while the product surface processed is highly polished, can effectively meet appearance requirement of the client to product.
Description
Technical field
The present invention relates to machinery manufacturing technology field, more particularly to a kind of railway locomotive left axle casing.
Background technology
Railway rail car axle box is the important composition part of heavy railway railcar, the part fifth wheel pair and bogie
Framework, due to overload of vehicle in actual use, so the situation of deformation crackle also occurs, the quality of the part is to whole
Car safety and stability has important influence.And traditional product is present because structure design falls behind, and technological level is relatively low
The problems such as.
The content of the invention
The technical problems to be solved by the invention are that the existing axle box mechanical property of solution is on the weak side, low intensity, manufacturability
The problems such as poor, difficulty of processing is big, cost is high, and product weight is heavier, and assembling is not light enough.Design proposes a kind of structure design letter
Single, reasonable, not only Product Process is good, and good mechanical performance, and quality is good, in light weight, while fabricates easy, cost
Low railway locomotive high-mechanic lightweight left axle casing.
In order to solve the above technical problems, the present invention realizes as follows：
A kind of railway locomotive high-mechanic lightweight left axle casing, including bearing hole (1), bolt hole (2), the first dovetail groove
(3), pin shaft hole (4), spring eye (5), right reinforcement (6), upper vertical plate (7), internal arm face (8), Draw bar lock tieholen (9), draining
Hole (10), screwed hole (11), left reinforcement (12), the second dovetail groove (13)；
Bearing hole (1) is the product central core part, connects mounting portion and left and right mounting portion up and down, bearing hole
(1) it is process by way of boring, be uniformly distributed six in bearing hole (1) exterior annular is process by the mode of drilling cuttings
Screwed hole (11), it is therefore an objective to improve installation accuracy and mounting stability in vehicle axles；
Bearing hole (1) bottom is provided with bolt hole (2) and the first dovetail groove (3), and bolt hole (2) is that machining center drilling cuttings forms
Hole；
The right side of bearing hole (1) is provided with right reinforcement (6) and spring eye (5), at spring eye (5) bottom by the way of boring
The center in face processes pin shaft hole (4), and osculum (10) is processed in the side of spring eye (5) with the mode of drilling cuttings, row
The place face in water hole (10) not only with core bearing hole (1) in one plane, also with spring eye (5) plane perpendicular, this
Sample ensures the dimensional tolerance of product so as to ensure the size of Product Assembly from the angle of technique；
Shelves and riser, which are cast with out, in bearing hole (1) upper part is used for processing internal arm face (8), Draw bar lock tieholen (9), on
Riser (7)；Upper vertical plate (7), internal arm face (8) and left reinforcement (12) are all connected with core bearing hole (1), using drilling cuttings
Mode process Draw bar lock tieholen (9) in the center of the second dovetail groove (13).
The positive effect of the present invention is：Axle box structure design of the present invention is simple, rationally, and it is by original ductile cast iron material
Manufactured integrative-structure, make the integrative-structure made of railroad track vehicle carbon steel material into, not only increase axle box
Overall mechanical properties, and make the manufacturability of axle box more preferable, difficulty of processing and the axle box for reducing axle box are overall
Weight, while the product surface processed is highly polished, can effectively meet appearance requirement of the client to product.
Brief description of the drawings
Fig. 1 is the stereogram of the present invention.
Fig. 2 is the left view of the present invention.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, a kind of railway locomotive left axle casing of the present invention, including bearing hole 1, bolt hole 2, first
Dovetail groove 3, pin shaft hole 4, spring eye 5, right reinforcement 6, upper vertical plate 7, internal arm face 8, Draw bar lock tieholen 9, osculum 10, screw thread
Hole 11, left reinforcement 12, the second dovetail groove 13.
Bearing hole 1 is the product central core part, connects mounting portion and left and right mounting portion up and down, and bearing hole 1 is logical
The mode for crossing boring is process, and six screw threads being process by the mode of drilling cuttings are uniformly distributed in the exterior annular of bearing hole 1
Hole 11, it is therefore an objective to improve installation accuracy and mounting stability in vehicle axles.
The bottom of bearing hole 1 is provided with the dovetail groove 3 of bolt hole 2 and first, the pore-forming for machining center drilling cuttings of bolt hole 2.
The right side of bearing hole 1 is provided with right reinforcement 6 and spring eye 5, at the center of the bottom surface of spring eye 5 by the way of boring
Position processes pin shaft hole 4, and osculum 10, the place face of osculum 10 are processed in the side of spring eye 5 with the mode of drilling cuttings
Not only with core bearing hole 1 in one plane, also so production is ensured from the angle of technique with the plane perpendicular of spring eye 5
The dimensional tolerance of product is so as to ensureing the size of Product Assembly.
Shelves are cast with out in the upper part of bearing hole 1 and riser is used for processing internal arm face 8, Draw bar lock tieholen 9, upper vertical plate 7；
Upper vertical plate 7, internal arm face 8 and left reinforcement 12 are all connected with core bearing hole 1, trapezoidal second by the way of drilling cuttings
The center of groove 13 processes Draw bar lock tieholen 9.
The mechanism of product is carried out improvement design by the present invention, in product structure design, blank manufacturing process and machining
Three aspects of technique, which start with improve and optimized, brings huge economic benefit.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention
