Abstract

The utility model discloses a rolling gripping axle box assembly which comprises a bearing box (7). The interior of a hole on the big end of the bearing box body (7) is provided with a rolling bearing (8), and the hole end is provided with a big end cover (1) and a big oil baffle ring (9); the interior of the hole on the small end of the bearing box body (7) is provided with a bearing box (4), and the interior of the hole is provided with a rolling bearing (2). An adjusting shim (3) is arranged between the small end surface of the bearing box body (7) and the bearing box (4); the end surface of the hole of the bearing box (4) is provided with a small end cover (6) and a small oil baffle ring (5); a fixing screw (10) is arranged between the ring-shaped slot bottom (11) of an outer circle of the big end cover (1) and the outer circle of a stopping opening of the cover. The gripping axle box is suitable for a quasi high-speed locomotive.

Description

The assembling of rolling axle suspension bearing box

The utility model relates to the assembling of a kind of rolling axle suspension bearing box, is specially adapted to the installation that connects of railway locomotive traction motor and axletree.

At present, on the French 8K type locomotive that moves on the railway line at home, traction motor connects the axle suspension bearing box of the rolling bearing type that is adopted with axletree, the screw that is fixedly connected between its casing and the big end cap is positioned at the below of big end cap cylindrical circular groove bottom land, that is: fix screw passes the groove edge of this groove, make the line of centers of this fix screw away from the line of centers of antifriction-bearing box, this just cause axle suspension bearing box be pulled electrical motor contain the part size too big, owing to be subjected to the restriction of homemade quasi high-speed locomotive installing space herein, so the axle suspension bearing box on the 8K type locomotive can not satisfy these needs; In addition, because the residing position of fix screw of the casing on this axle suspension bearing box and big end cap, make easily to be pulled lubricating oil that gear splashes along the outside seepage of the screw thread of fix screw.

The purpose of this utility model will provide a kind of rolling axle suspension bearing box assembling exactly, dwindles axle suspension bearing box and is pulled the size that electrical motor contains part, to satisfy the needs of homemade quasi high-speed locomotive, also can reduce lubricating oil along the outside seepage of the screw thread of fix screw.

The utility model is to realize like this, comprise: bearing housing, in the big stomidium of this bearing housing, antifriction-bearing box is housed, at this nose end big end cap and big oil seal washer are housed, in the little stomidium of bearing housing, bear box is housed, in its hole antifriction-bearing box is housed, between the small end end face of bearing housing and bear box, be provided with bearing cap shim, end face in the bear box hole is equipped with little end cap and little oil seal washer, is characterized in: be provided with fix screw between the seam cylindrical of the circular groove bottom land of big end cap cylindrical and this lid.

The rolling axle suspension bearing box assembling that the utility model relates to, owing to adopt with the line of centers of the screw that is fixedly connected between casing and the big end cap and the close method of line of centers of antifriction-bearing box, dwindle axle suspension bearing box and be pulled the size that electrical motor contains part, can satisfy the needs of homemade quasi high-speed locomotive, also can reduce lubricating oil along the outside seepage of the screw thread of fix screw.

Be described in detail the best technical application scheme of the rolling axle suspension bearing box assembling that the utility model relates to below in conjunction with accompanying drawing:

Fig. 1. be the longitudinal sectional view of the rolling axle suspension bearing box assembling that relates to of the utility model;

As shown in Figure 1, the rolling axle suspension bearing box assembling that the utility model relates to, comprise: bearing housing 7, in the big stomidium of this bearing housing, antifriction-bearing box 8 is housed, at this nose end big end cap 1 and big oil seal washer 9 are housed, in the little stomidium of bearing housing 7, bear box 4 is housed, antifriction-bearing box 2 is housed in its hole, between the small end end face of bearing housing 7 and bear box 4, be provided with bearing cap shim 3, end face in bear box 4 holes is equipped with small end lid 6 and little oil seal washer 5, is provided with fix screw 10 between the seam cylindrical of the circular groove bottom land 11 of big end cap 1 cylindrical and this lid.
