Abstract
The utility model relates to a gear box for railway locomotives, which is composed of an upper box body, a lower box body and an oil measuring tenon. The utility model is characterized in that side plates of the box bodies are fixedly connected with coaming plates of the box bodies in a flanging and wrapping shape. Stamper reinforcing ribs and ume-shaped fastening shim plates are arranged on the side plates. The openings of the upper box body and the lower box body are provided with fastening bolts with anti-looseness devices and locating pins of the box bodies. Magnetic bodies for adsorbing wear iron powder are arranged on the oil measuring tenon. Compared with the existing congener gear box, the integral strength and the shock resistance property of the utility model are enhanced. The utility model well controls and reduces the phenomena of easy relaxation, displacement and pull crack in high-speed operation, and can effectively prolong the service life of the box bodies.
Description
The utility model relates to a kind of railway road locomotive gear case, belongs to locomotive transmission auxiliary class.
Pass through the railway locomotive gear case of usefulness at present, its box side adopts dull and stereotyped welding, bulk strength and shockproof properties are poor, easily crack and cause interior storage oil seepage: fastener and backing plate between the two tanks are thin, easily produce loose, displacement and drawing crack phenomenon in the heavy duty high-speed cruising, the fricative iron of gear mesh end is not handled, both caused gear accelerated wear test easily to cause lubricant pollution waste in the case yet; Except the said structure defective, not handling owing to carrying out residual stress relieving after the casing moulding on the manufacture craft, make casing easily produce stress deformation and displacement, cause gear case eckband and axletree to produce the mechanical contact abrasion; Owing to adopt common welding, make slag inclusion, pore, the crackle quality problems of weld seam influence product design; Because casing is processed with standard machinery, is difficult to guarantee nowel joint gap standard, makes nowel mouth poor sealing performance.
Just because of above-mentioned numerous reason, cause the locomotive tooth to change the poor sealing performance that case exists for a long time, product quality problems such as yielding and crackle seepage.Obviously the existence of these defectives is the industry development requirements that are difficult to adapt to present stage " passenger traffic is quick, shipping is heavily loaded ".
The purpose of the present utility model: aim to provide a kind of locomotive gear case of new construction, not only strengthen its whole anti-deformation, drawing crack, earthquake-proof function can also be eliminated the harmful effect of casing store oil wearing and tearing iron foot couple gear and lubricating oil simultaneously; Improve the service life of gear case on the whole.
The technical solution of the utility model is as follows:
This railway locomotive is made up of upper box (1), lower box (2) and oil measurement bar (3) with gear case, it is affixed to it is characterized in that described box side (4) and casing coaming plate (5) are flanging bound edge shape, and pressing mold reinforced rib (6) and the fastening backing plate of blossom type (7) are set on this side plate simultaneously; On described, the unlatching mouth of lower box is except that fixing by bolt (8), and other is provided with a casing locating dowel pin (9), and described binding bolt (8) is provided with loosing-proof device; Described oil measurement bar (3) is provided with the magnetic substance (10) at an absorption iron end.
According to this railway locomotive gear case of above technical scheme design-calculated, pass through with installing locomotive gear cases with tradition and to compare, its advantage is: the bulk strength of casing and quakeproof and quake-resistant performance greatly improve, can very prevent from effectively to crack and high-speed cruising in loose, displacement and drawing crack phenomenon, and can effectively adsorb the iron end that produces in the gear wear, and both prolonged service life of gear, also save lubricating oil simultaneously.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, upper box; 2, lower box; 3, oil measurement bar; 4, box side;
5, casing coaming plate; 6, pressing mold reinforced rib; 7, fastening backing plate; 8, binding bolt;
9, locating dowel pin; 10, magnetic substance.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
Locomotive gear case as shown in the figure, except being different from the manufacture craft the conventional gears casing, (as after the casing moulding, carrying out the residual stress relieving treatment process, in the welding of casing, adopt the welding of import carbon dioxide welding machine, to last, the place that heals up of lower box body adopts the precision process for machining to handle), and on the structure of casing, made following several respects and improved.
First: pressing mold reinforced rib (6) is set on box side (4), and makes box side (4) and casing coaming plate (5) be the welding of flanging bound edge shape simultaneously, strengthened the intensity of casing itself and joint portion undoubtedly greatly.
Second: set up locating dowel pin (9) in the casing open portion, the binding bolt (8) of band loosing-proof device and the fastening backing plate of thickening (7) of blossom type; It is in service easily loose to solve fastener effectively, quality problems such as displacement and drawing crack; The loosing-proof device of wherein said binding bolt (8) can be a spring washer, also can be the member of other similar effect.
Three, adopt magnetic detection oil rod (3), this oil measurement bar (3) both can be to be made by magnetic material entirely, also can adopt as shown in the figure, settled one on it and added magnetic substance (10).The blossom type that adopts in such scheme is thickeied fastening backing plate (7), is not subjected to the restriction of flower type, also can be other any geometric scheme.
Claims (2)
1, a kind of railway locomotive uses gear case by upper box (1), lower box (2) and oil measurement bar (3) are formed, it is affixed to it is characterized in that described box side (4) and casing coaming plate (5) are flanging bound edge shape, and pressing mold reinforced rib (6) and the fastening backing plate of blossom type (7) are set on this side plate simultaneously; On described, the unlatching mouth of lower box is except that fixing by binding bolt (8), and other is provided with a locating dowel pin (9), and described binding bolt (8) is provided with loosing-proof device; Described oil measurement bar (3) is provided with absorption iron magnetic substance (10) not.
2, the barred body that a kind of railway locomotive gear case according to claim 1, described oil measurement bar (3) also are made up of magnetic material entirely.
