Abstract
The invention discloses a damping shaft-fixing device for a driving shaft of a train. The damping shaft-fixing device comprises a body, two sides of which are provided with a first fixed point and a second fixed point. The center of the body is provided with a penetrating shaft hole, around which a damping gasket is arranged. The body is made by high-strength converted steel. The damping gasket is made by novel high-strength abrasion-resistant and anti-resonance plastics. Due to the fact that the body for the damping shaft-fixing device for the driving shaft of the train is made by high-strength converted steel, safety in operation is ensured. Due to the fact that the damping gasket is made by novel high-strength abrasion-resistant and anti-resonance plastics, the damping gasket helps to effectively eliminate abrasion caused by resonance when the train operates at the constant speed.
Description
Technical field
The present invention relates to a kind of dead axle device, or rather, is a kind of train transmission shaft damping dead axle device.
Background technique
Train is in the process at the uniform velocity travelled for a long time, and easily cause resonance effect, once cause resonance, the destruction of causing is destructive.But existing dead axle device ignores resonance effect, there is potential danger.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of train transmission shaft damping dead axle device effectively can eliminating resonance.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of train transmission shaft damping dead axle device, comprises a body, establishes one first immovable point and one second immovable point respectively, establish one to run through axis hole at described body central in described body both sides, establish a damping gasket in the described axis hole surrounding that runs through.
As preferred embodiment of the present invention, described body is that high strength hard steel is made.
As preferred embodiment of the present invention, described damping gasket is that high strength wear resistant anti-resonance plastic cement is made.
Because the body described in train transmission shaft damping dead axle device of the present invention is that high strength hard steel is made, thus safety when running can be ensured.Because described damping gasket is that high strength wear resistant anti-resonance plastic cement is made, when train travels at the uniform speed, damping gasket effectively can eliminate the wearing and tearing of resonating and bringing.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological 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 some embodiments of the present invention, 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 perspective view of train transmission shaft damping dead axle device of the present invention;
Fig. 2 is the perspective view of the train transmission shaft damping dead axle device in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of train transmission shaft damping dead axle device effectively can eliminating resonance.
As shown in Figure 1 and Figure 2, a kind of train transmission shaft damping dead axle device 1, comprises a body 2, establishes one first immovable point 31 and one second immovable point 32 in described body 2 both sides respectively, establish one to run through axis hole 4 at described body 2 center, establish a damping gasket 5 in described axis hole 4 surrounding that runs through.
As shown in Figure 1 and Figure 2, described body 2 is made for high strength hard steel.
As shown in Figure 1 and Figure 2, described damping gasket 5 is made for high strength wear resistant anti-resonance plastic cement.
The body described in train transmission shaft damping dead axle device of this invention is that high strength hard steel is made, thus can ensure safety when running.Because described damping gasket is that high strength wear resistant anti-resonance plastic cement is made, when train travels at the uniform speed, damping gasket effectively can eliminate the wearing and tearing of resonating and bringing.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
