Abstract

The utility model relates to the field of machinary, a novel holder for on locomotive cylindrical roller bearing especially. It is including keeping the frame foundation, and the stand both sides that keep the frame foundation are for tying for the just double arc pocket hole of indent. Compare with prior art, have following characteristics: firstly, take out cylindrical roller and can not destroy other parts of bearing, secondly, only need to change a small amount of part, greatly reduced cost of maintenance, when just having shortened the maintainer, improved economic benefits, thirdly, the holder of wearability, impact toughness, the manufacturing of intensity geometric proportion HPb59 -1 ledrite has improvement by a wide margin, when needing to be changed the bearing, because the good wearability of holder can continue to utilize, fourthly, having improved the life of bearing, having practiced thrift the material, the cost is reduced has improved economic benefits.

Description

A kind of novel retainer on locomotive roller bearing

Technical field

The utility model relates to mechanical field, particularly a kind of novel retainer on locomotive roller bearing.

Background technique

Cylinder roller bearing retainer in the past on locomotive, as shown in Figure 1, material HPb59-1 lead brass manufactures, and under the condition low in locomotive running speed, maintenance period is short, can meet usage requirement.But along with locomotive speed raised speed to 90-140 kilometer by 60-90 kilometer per hour time, adopt the roller bearing of brass retainer just can not meet the usage requirement of locomotive, bearing is caused sharply to burn out, the frequency changing bearing is accelerated, maintenance cost significantly increases, and the normal operation of locomotive can not be ensured, transport order is upset sometimes, hinders the speed-raising of locomotive.In addition, existing retainer is generally adopt single pocket hole structure, and this structure roller dismounting difficulty, maintenance cost is high.

Model utility content

The purpose of this utility model is to provide a kind of novel retainer on locomotive roller bearing.

The purpose of this utility model is achieved through the following channels: a kind of novel retainer on locomotive roller bearing, it comprises maintenance stand, the column both sides keeping stand are arranged side by side and two arc pocket holes of indent, and described maintenance stand adopts bronze ZCuAL ₁₀fe ₃mn ₂make.

A kind of novel retainer on locomotive roller bearing of the utility model, compared with the prior art, has following features: one is that two arc pocket hole structure can take out cylindrical roller when dismantling bearing, and can not destroy other part of bearing; Two be roller bearing dismounting time, first take out separable inner ring, the pocket hole due to retainer is two arc pocket holes, and cylindrical roller easily just can take out, like this to the service condition of the outer ring of bearing, inner ring, cylindrical roller and retainer, the degree of wear, just can judge at any time the need of replacing etc., needs to change a whole set of bearing in the past, only need change a small amount of part now, significantly reduce maintenance cost, and shorten maintenance man-hours, improve economic benefit; Three is that retainer adopts bronze ZCuAL ₁₀fe ₃mn ₂manufacture, the retainer of its wear resistance, impact toughness, the manufacture of intensity geometric ratio HPb59-1 lead brass has and significantly improves, and when needing to change bearing, due to the wear resistance that retainer is good, can continue to utilize; Four is two arc pocket hole structures, only need take out the wear-out part such as cylindrical roller, the cylindrical roller more renewed load just can, do not change retainer, thus improve the working life of bearing, saved material, reduce cost, improve economic benefit.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is prior art structural representation;

Fig. 2 is the utility model structural representation;

Fig. 3 is the utility model partial enlargement structural representation;

In figure, keep stand 1, column 2, two arc pocket hole 3, rivet hole 4.

Embodiment

As shown in Figure 2 and Figure 3, a kind of novel retainer on locomotive roller bearing of the utility model, it comprises and keeps stand 1, and column 2 both sides keeping stand 1 are arranged side by side and two arc pocket holes 3 of indent.Described maintenance stand 1 adopts bronze ZCuAL ₁₀fe ₃mn ₂make.

The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.

Claims

1. the novel retainer on locomotive roller bearing, it comprises and keeps stand (1), it is characterized in that: column (2) both sides keeping stand (1) are arranged side by side and two arc pocket holes (3) of indent, and described maintenance stand (1) adopts bronze ZCuAL ₁₀fe ₃mn ₂make.
