Abstract
The utility model provides a single-sheet type coupling of a locomotive diesel engine. The single-sheet type coupling comprises a driving disc connected with a diesel engine crankshaft and a driven disc connected with a motor, wherein the driving disc and the driven disc are connected through a bolt structure; the driven disc adopts a single sheet structure, and adopts a stepped appearance with gradually decreased axial thickness from the axis in the radial direction; and the driving disc adopts a flywheel structure with large mass. The section of the driven disc adopts a thinner stepped structure, then displacement can be generated under axial impact, and a better buffer function on the impact of a motor rotor is achieved; the driving disc adopts the flywheel structure with large mass, so that the diesel engine operates more stably; and due to removal of a large quantity of reeds, the structure is simpler, and the cost is reduced remarkably.
Description
Technical field
The utility model relates to a kind of diesel engine of locomotive single-chip type shaft coupling, belongs to Diesel Engine Technique Field.
Background technique
On diesel engine of locomotive, the effect of shaft coupling is to connect diesel engine and main generator, plays the effect that connects and transmit merit.Simultaneously, due to the impact to diesel engine of the inertial force of locomotive brake drive motor rotor, shaft coupling also needs to have the effect of buffer motor rotor inertial forces.In prior art, using more is a kind of reed-type shaft coupling.As shown in Figure 1, driving disc connects crankshaft of diesel engine to the structure of reed-type shaft coupling, and driven disc connects motor, and middle steel disc is corrugated structure.When locomotive emergency start-stop, motor can make crankshaft of diesel engine produce axial displacement to the inertial force of driven disc, and diesel-engine body is produced and impacted.Steel disc act as absorption axial displacement, alleviate the impact force of motor to diesel engine.But this reed-type shaft coupling effectiveness in vibration suppression is unsatisfactory, and complex structure, and manufacture cost is higher.
Model utility content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of diesel engine of locomotive single-chip type shaft coupling is provided.
The purpose of this utility model is achieved in that a kind of diesel engine of locomotive single-chip type shaft coupling, comprise the driving disc that connects crankshaft of diesel engine and the driven disc that is connected motor, driving disc is connected by bolt arrangement with driven disc, it is characterized in that described driven disc is monolithic structure, its axial thickness is the stepped shaft radially successively decreasing gradually from axle center.
In order to realize better the purpose of this utility model, described driving disc is for being equipped with the flywheel structure of large quality.
Scheme of the present utility model, because driven disc section is thinner ladder-type structure, under axial impact, can produce displacement, and the impact force of rotor is had to good buffer function; Because driving disc is for being equipped with the flywheel structure of large quality, can make diesel engine running more steady; Owing to having removed a large amount of reeds, structure is become simply, and significantly reduce costs.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's diesel engine of locomotive single-chip type shaft coupling schematic diagram.
Fig. 2 is that one chip stepped shaft driven disc is out of shape schematic diagram under the effect of axial force.
In figure, be labeled as: 1-flywheel-type driving disc, 2-gear ring, 3-stepped shaft driven disc, 4-bolt arrangement.
Embodiment
For making the utility model embodiment's object, technological scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the diesel engine of locomotive single-chip type shaft coupling of the present embodiment, left side driving disc 1 connects crankshaft of diesel engine, and right side driven disc 3 connects motor, and bolt arrangement 4 is fixed together driving disc 1 and driven disc 3.Middle startup gear ring 2 is fixed by bolts on driving disc 1, drives diesel engine to rotate when diesel engine starting.
In order to guarantee the Security of transmitting torque, for flywheel-type driving disc 1 has been equipped with larger thickness and quality, in diesel engine running, play energy storage.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
