Abstract
The utility model relates to an anti-leakage locomotive gearbox, which comprises a box body. The box body comprises an upper box and a lower box buckled together and is provided with a fixation base which comprises a screw base and an adjustment nut screwed on outer threads of the screw base. The inside of the screw base is provided with inner screw holes of the same axes as the outer threads. Owning to the adoption of an adjustable fixation base on the locomotive box body, the loosing problem under bigger impulse vibration is solved. Changing the prior structure into an adjustable fixation base achieves simultaneous installation and adjustment and solves the problem of gearbox loosing radically. Regarding sealing problem, an oil-receiving seal strip is adopted on a third upper box, which mainly functions in receiving oil and guiding oil and an oil-scraping seal strip is adopted on the lower box, which mainly functions in scraping oil and treating oil. Seen from the experiment result, the reconstruction generates a very obvious effect.
Description
Technical field
The utility model relates to a kind of installing locomotive gear cases, belongs to field of mechanical technique.
Background technology
Internal combustion, electric locomotive gear case are to go up the nowel welded-steel plate construction, because its installation site and space are restricted, the train operation vibration is bigger, and its impact acceleration reaches 10g, thereby cause the gear housing pine, split, leak, and become locomotive one inertial defect.Particularly behind the railway speed increase, this fault is more frequent, and the one, cause gear pernicious running under the oil starvation situation, cause the flank of tooth to peel off, the 2nd, the oil leaking pollution environment, the 3rd, increased working strength of workers, the 4th, the stopping time increases, and has reduced the operating efficiency of locomotive.Problems such as change this state, key will be set about from the installation of gear case, and solution is loose, leak, split.
The utility model content
The purpose of this utility model is to provide a kind of leakage proof installing locomotive gear cases, with the pine that solves casing, the problem of splitting, leaking.
For implementing above-mentioned purpose, the utility model has adopted a kind of leakage proof installing locomotive gear cases, comprise casing, casing is fastened by upper box and lower box and forms, be fixed with the casing fixed mounting on the casing, fixed mounting is made of spin-on adjustment nut on spiral shell seat and the spiral shell seat outside thread, is provided with the inner bolt hole with the outside thread coaxial line in the spiral shell seat.
Described adjustment nut perisporium is provided with one or more radially screw, and each radially is installed with a tie down screw in the screw, and the top of tie down screw is conical.
The inner port place of described spiral shell seat inner bolt hole is fixed with the anti-loose ring that can be made by the material that the attachment bolt that screws in the inner bolt hole is shot, and the internal diameter of anti-loose ring is not more than the path size of spiral shell seat negative thread.
There is the anchor ring plug that turns in an outer end of described adjustment nut, and the aperture dimension of plug is not less than the big footpath size of spiral shell seat negative thread, and the external port place of plug fixedly is embedded with a bump protection ring, and the bump protection ring outer face is higher than the outer face of plug.
The static seal eckband hole wall of described casing is provided with two radial ringed grooves, be embedded with the duplex sealing band that a circle is made of two sealing units in two cannelures, the top of each sealing unit cross-sectional plane is semi-cylindrical sealing, the bottom is an isosceles trapezoid setting-in portion wide at the top and narrow at the bottom, and setting-in portion is inlaid in the cannelure of correspondingly-shaped.
From outside to inside being provided with three cannelures, setting-in one ring cross-section is the felt sealing band of rectangle in the outer circular groove on the dynamic seal eckband hole wall of described casing; Setting-in one circle rubber weather strip in the middle cannelure, the top of rubber weather strip is half-cylindrical sealing, the bottom is a rectangle setting-in portion, leans on the first half of the cannelure of lining to be embedded with half-turn rubber Oil reception seal strip, and lower part is embedded with half-turn wiper seal bar.
The top of described Oil reception seal strip is the sealing that is made of two " V " shape seal lands, stretch out one on the medial surface and upwarp and connect oil groove, the top of described wiper seal bar be inwardly above bevelled frizing sword.
The outside at the upper box of described casing and lower box fastening place respectively is welded with a fit sealing piece, fit sealing piece and casing junction respectively are provided with a groove up and down, be embedded with " O " shape rubber weather strip in the groove, the fit sealing piece is fixed together by binding bolt up and down.
Owing to adopted adjustable fixed mounting on the locomotive casing, solved the loosening problem under the bigger situation of impact shock.The adjustment that original gear case installs and fixes the position is to realize by the packing ring of different-thickness, range estimation earlier needs several packing rings, after adding, if it is improper, also need hold-down bolt Panasonic, increase and decrease packing ring again, because a plurality of packing rings are under the impact shock situation, displacement mutually causes the fastening force of bolt to reduce between the packing ring, make the installation place become articulated structure, gear case and connector vibrate mutually, cause the casing crackle, sealing place gap increase, hold-down bolt fractures, and this is the basic reason that causes the gear case major issue.Original design is made into adjustable fixed mounting, adjust, make the problem of gear case pine reach basic solution while reach to install.On sealing problem, original design is to seal with malthoid, though make twice into from sealing together the earliest, all do not reach better effects, this is because the design of malthoid mainly is dustproof, add train speed raising in addition, speed is improved, and malthoid can not adapt to present requirement, and what have also makes rubber seal into, because its structure design is unreasonable, effect is also undesirable.The utility model is according to its actual application site, adopt different version, the static seal place adopts duplex " O " shape, play supporting vibration damping, the effect of sealing do, dynamic seal place is easy oil leakage place, adopt three seals, first road, the outside adopts malthoid to play dustproof effect, middle employing simply connected O shape is played supporting, main sealing function, and the 3rd road top box adopts Oil reception seal strip, mainly works the oily Oil Guide effect that connects, nowel adopts the wiper seal bar, mainly play the frizing oleophobic effect, more than transform on experimental result, effect is very obvious.At the fastening place of casing, original design is to use lower plugboard, and faying face is coated with grease resistance, its result seals better in earlier stage, use one section after because the vibration, the continuous displacement in faying face place, cause stop-leak compound to come off, the slit is owing to box deformation strengthens, and the junction leakage of oil becomes common common fault, the utility model makes " O " shape rubber weather strip into, the one, alleviate labor strength, the 2nd, solve the long-term use junction and produced sealing problem behind the slit, simple and practical.
