Abstract
The utility model relates to a shaft holding bush which is used for the shaft holding system of an electric locomotive. The phenomenon of serious oil leakage of the common gear box of the SS3 type electric locomotive exists. The product structure is that the inner surface of the shaft holding bush in the vicinity of one end of the gear box is provided with annular concave grooves from one to four, and the concave grooves are embedded with sealing material. The sealing material can be felt strips, rubber, etc. The concave grooves are rectangular, and are two. The utility model has the advantages that the utility model solves the problems of the oil leakage of the gear box of the SS3 type electric locomotive, influencing the lubrication of the hauling gear of the locomotive and increasing transportation cost, and reduces the dosage of shaft holding fuel and the work load of the daily fuel maintenance of the gear box.
Description
The utility model is the used axle suspension bush of a kind of electric locomotive seize system.
SS3 type electric locomotive original design draws big miniature gears and adopts hyperbolic gear oil lubrication, seize to adopt axle oil lubricated, because of the seize fuel tank communicates with gear case, causes in the locomotive operation process, and hypoid gear oil is scurried mutually in seize oil and the gear case.Its consequence is: two kinds of oil mix, and influence lubricant effect; After seize oil enters gear case, make the gear case oil level too high, during locomotive operation, gear transmission causes the gear case internal pressure excessive, adds that thin oil seal itself is exactly a difficult problem, thereby causes the serious leakage of oil of the general gear case of SS3 type electric locomotive, not only contaminated environment, and increase traffic cost.One of measure that addresses this problem is that traction gear adopts ND5 gear grease lubrication, but must prevent that gear fat anti-channeling in the gear case from going into axle suspension bearing box and causing and roll over watt that this is unsolved so far problem.
The purpose of this utility model is that the structure of former axle suspension bush is improved, and the seize oil in the seize fuel tank is not scurried mutually with the ND5 gear fat in the traction gearbox, and making specifically provides a kind of electric locomotive axle suspension bush with sealing band.
Axle suspension bush is the major part of seize system.The axle suspension bush that uses in the SS3 type electric locomotive is at present all adopted copper back of the body cast alloys.Because of the seize neck of each parts of seize system and axletree determines that this has just determined axle suspension bush can not do big change.
Structure of the present utility model is: the inside face of axle suspension bush has one to four annular groove near an end of gear case, and groove is embedded with leakproofing material.Said leakproofing material can be felt bar, rubber etc.Said groove is preferably rectangle, and is two.
The beneficial effects of the utility model be thoroughly solved the leakage of oil of SS3 type electric locomotive gear case, to influence locomotive traction gear lubricated, increase traffic cost and the problem that influences the civilized state of locomotive, and reduced the work capacity of the daily oil maintenance of the consumption of seize oil and gear case, have remarkable economic efficiency and certain social benefit.
Fig. 1 is the example structure scheme drawing, and wherein: A is main looking, and B is right optic zone local section, and C is the section of the D-D among the A.
Fig. 2 is the rigging position scheme drawing of embodiment.
Embodiment: see Fig. 1-2.The inside face of axle suspension bush 1 has two annular rectangular recess near an end of traction gearbox 2, groove is embedded with leakproofing material 3 and 4, and bond with adhesives, make sealing band 3,4 as a whole with 1 one-tenth of axle suspension bush, leakproofing material 3 is highly dense felt bar, and leakproofing material 4 is a polyamine fat rubber strip.Groove size is wide 8 millimeters, dark 4 millimeters.7 is right for wheel among the figure, and 8 is gear.Between watt back of the body and the seize 5 is static relatively, and this partly seals and belongs to static sealing, seals with 587 sealants of U.S. Le Tai company.When locomotive operation, be relative motion between axle suspension bush 1 and the axletree 6, and fill between axle suspension bush 1 and the axletree 6 and permitted the 0.2-2 mm clearance that this part sealing belongs to dynamic seal (packing).Add ND5 gear fat in the gear case.About the every operation of locomotive 30000km, each gear case is mended ND5 gear fat 1kg, traction gearbox 2 no leaks.Shafting oil does not take place this locomotive on inspection and gear fat is scurried phenomenon mutually, and watt fault does not take place to roll in the utilization process.
Claims (2)
1, a kind of electric locomotive axle suspension bush with sealing band is characterized in that: the inside face of axle suspension bush has one to four annular groove near an end of gear case, and groove is embedded with leakproofing material.
2, as the said electric locomotive axle suspension bush of claim 1, it is characterized in that: groove is a rectangle, and quantity is two.
