Abstract

The utility model relates to a railway engine gear box, in particular to an engine oil leakageproof gear box, which comprises a box body (3) and a static seal neck hole (2) equipped between the box body (3) and the axle box flange (1). The utility model is characterized in that the static seal neck hole (2) is opposed to the axle box flange (1), and the surface having the sealed action is in jagged shape. The high-frequency impulse of the gear box and the pulling motor during the operation of the engine can be overcome; the vibration reduction and anti-pressure property of the static seal neck hole are reinforced; the lubricant grease leakage because of the relative displacement and sliding of the gear box and the sealed collar brought by the horizontal movement of the pulling motor is prevented. The sealed equalization with the strip side of the hair felt can be automatically adjusted during the built-up process of the gear box; the verticality of the box body is ensured, and the sealed effected is good.

Description

Locomotive leakproof oilgear case

Technical field

The utility model relates to the railway locomotive gear case, especially a kind of locomotive leakproof oilgear case.

Background technology

Railway locomotive gear case working environment is relatively poor, so it is very high to seal request, with the electric locomotive of SS3 type is example, and the static seal between the casing of its gear case and the axle suspension bearing box flange mainly adopts the long strip type Oil Resistant Rubber Plate, takes to overlay mode and carries out, but in actual applications, because less, the weak strength of Oil Resistant Rubber Plate material stroke, shock resistance is poor, can not satisfy the installing locomotive gear cases operating needs fully, oil leakage phenomenon takes place easily, influences traffic safety.

Summary of the invention

It is better that the purpose of this utility model provides a kind of sealing property, the locomotive leakproof oilgear case of not easy oil leakage.

The technical solution of the utility model is as follows:

A kind of locomotive leakproof oilgear case comprises casing and the static seal eckband between casing and axle suspension bearing box flange, and its special feature is, relative with the axle suspension bearing box flange on the described static seal eckband, the surperficial indentation that seals.

Wherein the projection on the hackly surface all distributes along static seal eckband length direction.

Wherein the surface that contacts with casing on the static seal eckband is the groove that cooperates with casing.

Wherein the static seal eckband is made up of with upper and lower casing two the static seal eckbands that cooperate that heal up respectively its surface groove.

Wherein the static seal eckband is a polyamine fat material.

The utility model has adopted the novel static seal eckband that has serrated face and gulde edge, has following effect:

(1) for overcoming the high-frequency percussion of locomotive operation middle gear case and traction electric machine, sealing band is designed to the compression seal face and sawtooth seals the mode that combines, strengthened the vibration damping and the compressive property of static seal eckband;

(2) this static seal eckband has designed gulde edge, clamps gear case by gulde edge and heals up, and has overcome in the locomotive operation to sew because of the traction electric machine side travel causes gear case and the sealing neck bar relative displacement and the lubricating grease that causes that slides;

(3) the serrated seal mask of static seal eckband has elasticity preferably, but the sealing equilibrium of automatic compensation and felt bar side in the gear case assembling process guarantees that casing is vertical, and sealing effectiveness is good.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the structural representation of static seal eckband (2) in the utility model;

Accompanying drawing 3 is that the A-A of accompanying drawing 2 is to cutaway view;

Accompanying drawing 4 is the birds-eye view of accompanying drawing 2.

The specific embodiment

Come the utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1, locomotive leakproof oilgear case comprises casing 3 and the static seal eckband 2 between casing 3 and axle suspension bearing

box flange

1,1 relative on the static seal eckband 2, as to seal surface 202 indentations with the axle suspension bearing box flange, as shown in Figure 3, wherein the projection on the hackly surface all distributes along static seal eckband 2 length directions, be that on the hackly surface some projectioies are parallel and vertical substantially with main shaft substantially, thereby play the better seal effect, avoid lubricating grease to sew.

Shown in Fig. 2,3,4, the surface that contacts with casing 3 on the static seal eckband 2 is the groove 201 that cooperates with casing 3, promptly formed and the gear case gulde edge that cooperates of place that heals up on its surface, because installing locomotive gear cases is made up of upper and lower casing two parts, therefore static seal eckband 2 can have two, its separately surface groove cooperate with upper and lower casing respectively, thereby by the semicircle that gulde edge the is clamped upper and lower casing place that heals up, adopt long static seal eckband 2 also can certainly separately.

Static seal eckband 2 can adopt polyamine fat or other elastomeric material to manufacture.

Claims

1, a kind of locomotive leakproof oilgear case, comprise casing (3) and the static seal eckband (2) between casing (3) and axle suspension bearing box flange (1), it is characterized in that: described static seal eckband (2) is gone up surface (202) indentation relative with axle suspension bearing box flange (1), that seal.

2, locomotive leakproof oilgear case as claimed in claim 1 is characterized in that: wherein the projection on the hackly surface all distributes along static seal eckband (2) length direction.

3, locomotive leakproof oilgear case as claimed in claim 1 or 2 is characterized in that: wherein the last surface that contacts with casing (3) of static seal eckband (2) is the groove (201) that cooperates with casing (3).
