Abstract
The invention provides a bearing pressing cover and a hollow axle system, wherein the bearing pressing cover comprises a bearing pressing cover body and a seal ring which is fit with the inner side of the bearing pressing cover body; the hollow axle system comprises a hollow axle, a bearing and a bearing pressing cover, wherein the bearing is pressed and installed at the tail end of the hollow axle; the bearing pressing cover is fixedly connected with the end surface of the hollow axle and axially limits the bearing; the bearing pressing cover comprises a bearing pressing cover body and a seal ring which is fit with the inner side of the bearing pressing cover body; and the seal ring is positioned between the end surface of the hollow axle and the bearing pressing cover body. Through the seal function of the bearing pressing cover, after the hollow axle is subjected to non-destructive inspection, a coupling liquid can not be residual between the bearing pressing cover and the end surface of the hollow axle, thus the residual coupling liquid is prevented from entering the bearing and causing adverse influences to performances of the bearing.
Description
Technical field
The present invention relates to railway vehicle and make the field, relate in particular to a kind of bearing gland and hole-bored axle from end to end system.
Background technique
Bearing gland is the strength member of connection bearing and axle base part.What adopt on the bogie of at present domestic most of Harmony EMU all is that hole-bored axle from end to end adds the bearing gland structure.When hole-bored axle from end to end is carried out nondestructive inspection,, need not dismantle bearing gland generally speaking and just can directly carry out nondestructive inspection hole-bored axle from end to end in order to save dismounting and built-up time.
And after the flaw detection; Injecting the inner coupling liquid of hole-bored axle from end to end will remain between hole-bored axle from end to end end face and the bearing gland; Residual coupling liquid can get into bearing through the binding site of bearing gland and axletree; Influence the usability of bearing, traffic safety is affected, can increase the cost of overhaul and maintenance cost simultaneously.

Embodiment
Fig. 2 is a bearing gland example structure schematic representation of the present invention, and is as shown in Figure 2, and bearing gland 60 comprises bearing gland body 601 and the seal ring 602 of fitting with its inboard.Present embodiment adopts seal ring 602 is partially submerged into the compound mode in the seal groove on the bearing gland body 601; Bearing gland body 601 can also be bonding combination or dismountable other combining form with seal ring 602, and the present invention does not limit the concrete form of this combination.Bearing gland body 601 is provided with three bolts hole 603 that are used for construction bolt, and the quantity of bolt hole 603 can increase and decrease as required among other embodiment.Bearing gland body 601 center portions also are provided with a through hole 604, import coupling liquid and fixation hollow axletree when being used for hole-bored axle from end to end detected a flaw.
There is the hole-bored axle from end to end system of sealing function bearing gland to elaborate with regard to use provided by the invention below; Fig. 3 is the stereogram of hole-bored axle from end to end system embodiment of the present invention; As shown in Figure 3; Bearing 20 is fitted in the end of hole-bored axle from end to end 10, and bearing gland 60 is fixed in the axial end of hole-bored axle from end to end 10 through bolt 40, and bearing 20 is played the axial limiting effect.Because the seal ring (not drawing) that comprises in the bearing gland 60 is between the end face of bearing gland body and hole-bored axle from end to end 10; Thereby avoided after hole-bored axle from end to end 10 flaw detections; Coupling liquid remains in this position; And then avoided residual coupling liquid to get into bearing 20, and influence the usability of bearing 20, traffic safety is impacted.The present invention also can make up use with all hollow shafts that need under the situation of not dismantling bearing gland and bearing, detect a flaw, is not only limited to hole-bored axle from end to end and makes up.
Fig. 4 is the knot face figure of hole-bored axle from end to end system embodiment of the present invention, and as shown in Figure 4, bearing 20 is fitted in the end of hole-bored axle from end to end 10, and bearing gland 60 is fixed in the end face of hole-bored axle from end to end 10 and bearing 20 is played the axial limiting effect through bolt 40.Wherein bearing gland 60 comprises bearing gland body 601 and the seal ring 602 of fitting with its inboard; Because seal ring 602 is between the end face of bearing gland body 601 and hole-bored axle from end to end 10; Thereby avoided after hole-bored axle from end to end 10 flaw detections; Coupling liquid remains in this position, and then has avoided residual coupling liquid to get into bearing 20, influences the usability of bearing 20.
Present embodiment middle (center) bearing gland 60 is affixed through bolt 40 and hole-bored axle from end to end 10; Under other enforcement situation; Yet can bearing gland is designed to have the parts of internal thread and directly tighten and carry out affixed (not accompanying drawing) with having externally threaded hole-bored axle from end to end, the present invention limit this affixed mode.
The invention provides a kind of topology layout compact and reasonable; The bearing gland of novel structure and hole-bored axle from end to end system because this structure is equipped with seal ring, can effectively solve the hole-bored axle from end to end flaw detection after; The too much residual and entering bearing of coupling liquid; And then influence the problem of bearing usability, and this structure just does very little change on original structure, can not increase manufacture cycle and manufacture cost.
What should explain at last is: above each embodiment is only in order to explaining technological scheme of the present invention, but not to its restriction; Although the present invention has been carried out detailed explanation with reference to aforementioned each embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, perhaps to wherein part or all technical characteristic are equal to replacement; And these are revised or replacement, do not make the scope of the essence disengaging various embodiments of the present invention technological scheme of relevant art scheme.
