Abstract
The utility model proposes a kind of bearing cap of locomotive, comprising: lid and axle sleeve, described axle sleeve offers link slot, described lid is fixed in link slot, is provided with damping pad and this damping pad and lid fit tightly in described link slot; The end of described axle sleeve is provided with the holding section for clamping damping pad and lid along the radial direction of axle sleeve.Solve prior art middle (center) bearing and axle sleeve severe friction, cause bearing or axle sleeve wearing and tearing, thus cause bear vibration and send noise and bearing cap life-span short problem.
Description
Technical field
The utility model relates to motor vehicle components technical field, refers to a kind of bearing cap of locomotive especially.
Background technology
The bearing cap of locomotive has axle sleeve, axle sleeve and rotation axis matched in clearance.Locomotive running speed is higher, and traction electric machine drives rotation axis rotation also to improve thereupon; Rotation axis is high speed rotating in axle sleeve, and severe friction produces high heat.Lubricating grease is scribbled, for lubrication and cooling in axle sleeve; But lubricating grease does not circulate, because rotating heating in bearing rotation process, to go bad, aging and softening; Bearing, after losing the lubrication and cooling of lubricating grease, can produce severe friction with axle sleeve, causes bearing or axle sleeve wearing and tearing, thus causes bear vibration and send noise; Bearing cap produces slight crack because of vibration, even ruptures.
Utility model content
The utility model proposes a kind of bearing cap of locomotive, solve prior art middle (center) bearing and axle sleeve severe friction, cause bearing or axle sleeve wearing and tearing, thus cause bear vibration and send noise and bearing cap life-span short problem.
The technical solution of the utility model is achieved in that a kind of bearing cap of locomotive, comprise: lid and axle sleeve, is characterized in that, described axle sleeve offers link slot, described lid is fixed in link slot, is provided with damping pad and this damping pad and lid fit tightly in described link slot; The end of described axle sleeve is provided with the holding section for clamping damping pad and lid along the radial direction of axle sleeve.
Setting like this, when bearing and axle sleeve severe friction produce and vibrate, damping pad can alleviate vibration, also alleviates because of the damage of vibration to bearing cap simultaneously.
Preferably, described lid is made up of lid section one, lid section two and lid section three, and described lid Duan Yiyu lid section two bending connects, and the transition of lid Duan Eryu lid section three-arc connects.
Setting like this, lid is designed to bending type and adopts arc transition, effectively can obtain the stress that decomposition vibration produces, alleviate the damage to bearing cap further.
Preferably, described lid Duan Sancheng bending type be bent to form an installation cavity.
Preferably, the inwall of described axle sleeve is coated with wearing layer.
Setting like this, the overall resistance to wear improving axle sleeve.
Preferably, described holding section and axle sleeve arc transition one-body molded.
Preferably, circular arc relief section is provided with between described installation cavity and lid section two.
The beneficial effects of the utility model:
This bearing cover is simple, and resistance to wear is high; There is the function of damping and reduction noise, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model axle sleeve.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of bearing cap of locomotive, comprises lid 1 and axle sleeve 3.The periphery entering axle sleeve 3 end at bearing offers a link slot 31.Lid 1 is made up of lid section 1, lid section 2 12 and lid section 3 13.Lid section 1 is fixed in link slot 31, and both are by welding together.Lid section 1 bends with lid section 2 12 and is connected, and lid section 2 12 is connected with lid section 3 13 arc transition.Lid 1 is designed to bending type and adopts arc transition, effectively can obtain the stress that decomposition vibration produces, alleviate the damage to bearing cap further.Preventing lid 1 and damping pad 2 from vibrate in link slot 31 internal cause produces loosening, and the end of axle sleeve 3 is provided with holding section 32 along the radial direction of axle sleeve 3.Holding section 32 is one-body molded with axle sleeve 1 arc transition.
Wherein, lid section 3 13 is bending type and is bent to form an installation cavity 4.Install between cavity 4 and lid section 2 12 and be provided with circular arc relief section 14.
Wherein, damping pad 2 is provided with and this damping pad 2 and lid 1 fit tightly (damping pad 2 is positioned at the side of lid 1 near bearing) bearing and axle sleeve severe friction produces when vibrating in link slot 31, damping pad can alleviate vibration, also alleviates because of the damage of vibration to bearing cap simultaneously.
In addition, the inwall of axle sleeve 3 is coated with wearing layer (depending on going out), in order to entirety improves the resistance to wear of axle sleeve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
