Fig. 1 is the utility model locomotive traction gear embodiment's stereogram; Fig. 2 is the sectional view of Fig. 1.A locomotive traction gear, comprising: external toothing 1, in external toothing 1, be coaxially arranged with discoid core wheel 2, forms the first gap between core wheel 2 and the inner side surface of external toothing 1; The outer side surface of core wheel 2 is formed with the first cantilever 21 radially stretching out outwardly, on the inner side surface of external toothing 1, corresponding the first cantilever 21 is formed with the second cantilever 12 radially stretching out inwardly; The first cantilever 21 is fixedly connected with by least one connecting pin 3 relatively with the second cantilever 12.
Particularly, it is circular that external toothing 1 can be, and outer side surface is provided with a plurality of gear teeth 101, and inner side surface surrounds a circular port; Core wheel 2 can coaxially be arranged in external toothing 1, and the thickness of core wheel 2 can match with the thickness of external toothing 1, and the circumference side of core wheel 2 is relative with the inner side surface of external toothing 1; Between the inner side surface of the outer side surface of core wheel 2 and external toothing 1, form the first gap, the large I in this first gap is determined according to the size of external toothing 1 and core wheel 2.
On the side of core wheel 2, can one be fixedly installed at least two the first cantilevers 21, the first cantilever 21 radially stretches out along core wheel 2 outside core wheel 2, the second cantilever 12 can one be fixedly installed on the inner side surface of external toothing 1, certainly, the first cantilever 21 and the second cantilever 12 also can be fixedly attached on core wheel 2 and external toothing 1 for individual components and by modes such as welding.Each first cantilever 21 size and dimensions can be identical, and similarly, the size and dimension of each second cantilever 12 also can be identical; The length that the first cantilever 21 and the second cantilever 12 extend radially is less than or equal to respectively above-mentioned the first gap, and the gap between two adjacent the first cantilevers 21 is greater than the second cantilever 12 in upwardly extending length of week; Each second cantilever 12 can be corresponding one by one with the first cantilever 21, the position in the first gap that the first cantilever 21 forms with core wheel 2 at external toothing 1 with the second cantilever 12 is corresponding, for example, the first cantilever 21 can be deep into above or below the second corresponding cantilever 12, both are fixed together by vertically running through the connecting pin 3 of the first cantilever 21 and the second cantilever 12.
Core wheel 2 and external toothing 1 in the locomotive traction gear that the present embodiment provides can be distinguished manufacturing, and then utilize connecting pin 3 by core wheel 2 together with external toothing 1 pin joint, thereby core wheel 2 is fixedly connected with and is integral with external toothing 1.
The locomotive traction gear that the present embodiment provides, by separate core wheel and external toothing are set, and by the connecting pin of the first cantilever through on core wheel and the second cantilever on external toothing, core wheel is fixedly connected with and is integral with external toothing, realized after long-time use, when the gear teeth on external toothing are worn and cannot use, pull down external toothing, be replaced with after new external toothing, recycling connecting pin retightens core wheel and external toothing to link into an integrated entity, compare with the gear that integral replacing in prior art is new, greatly saved material, reduced locomotive maintenance cost.
Further, the first cantilever 21 can comprise the supporting plate 211 being oppositely arranged, and wherein each supporting plate 211 one end can be fixedly connected on core wheel 2, the other end stretches out core wheel 2 outsides; Supporting plate 211 can be perpendicular to the axial setting of core wheel 2, and supporting plate 211 can be parallel to end face or the bottom surface of core wheel 2, and forms the gap matching with the second cantilever 12 thickness between two relative supporting plates 211; The second cantilever 12 extend between two supporting plates 211 of the first corresponding cantilever 21, and two connecting pins 3 can run through supporting plate and the second cantilever 12; That is to say, connecting pin 3 can run through a supporting plate 211, the second cantilever 12 and another supporting plate 211 successively, thereby realizes being fixedly connected with between the first cantilever 21 and the second cantilever 12.
Preferably, the first cantilever 21 and the second cantilever 12 all can equate for the interval between five and each first cantilever 21 and/or between the second cantilever 12; The first cantilever 21 is distributed on core wheel 2 around, and the second cantilever 12 is distributed on the circular hole circumference that external toothing 1 inner side surface surrounds.
It should be noted that, gap between two adjacent the first cantilevers 21 can be determined according to the second cantilever 12, gap between two adjacent the second cantilevers 12 can be definite according to the first cantilever 12, and the space that can hold between next the first cantilever 21, while the first cantilever 21 with the space guaranteeing between the second cantilever 12 can hold next the second cantilever 12.Like this, in the time of together with external toothing 1 being installed to core wheel 2 at needs, can first by core wheel 2 belows or below, external toothing 1 coaxial sleeve be set to core wheel 2 peripheries, the angle in the gap between corresponding two the first cantilevers 21 of the second cantilever 12 can be moved external toothing 1 vertically gradually towards core wheel 2, until the gap between two supporting plates 211 of the second cantilever 12 and the first cantilever 21 is when align, just can central shaft be that axle rotates external toothing 1 or core wheel 2, the second cantilever 12 is entered between two supporting plates 211, then just can utilize connecting pin 3 to achieve a fixed connection through supporting plate 211 and the second cantilever 12.
Adopt the form of two supporting plate sandwiched the second cantilevers, the reliability and stability that are fixedly connected with have further been guaranteed, and by the relative position between the first cantilever and the second cantilever is rationally set, also guaranteed to realize easily and quickly assembling and the connection between core wheel and external toothing.
The hole wall that further, can be respectively arranged with the pin-and-hole 23 on pin-and-hole 23, the second cantilevers 12 on supporting plate 211 and the second cantilever 12 is fixedly installed elastic rubber layer 24.
Particularly, elastic rubber layer 24 can be fixed into one for a rubber tube and by the pin-and-hole 23 on sulfuration process and the second cantilever 12; By the setting of this elastic rubber layer 24, the second cantilever 12 of rigidity can be contacted to the Elastic Contact being converted between elastic rubber layer 24 and connecting pin 3 with the rigidity between connecting pin 3, having realized flexible pin connects, can effectively reduce the vibration in working gear process, reduce noise, improve the performance of gear.
The utility model is another embodiment provide a kind of locomotive, comprising: motor, and as above described in arbitrary embodiment, for by the locomotive traction gear of the moment of torsion output of this motor; The output shaft of motor can form and drive the gear teeth or fixing sheathed actuation gear; By these driving gear teeth or actuation gear, be meshed with locomotive traction gear, the moment of torsion of motor is passed to the motorcycle axle meshing with locomotive traction gear; Wherein, the concrete structure of locomotive traction gear and function and aforementioned each embodiment are similar, repeat no more herein.
The locomotive that the present embodiment provides, by adopting the structure being linked into an integrated entity by connecting pin by core wheel and external toothing, realized after long-time use, when the gear teeth on external toothing are worn and cannot use, pull down external toothing, be replaced with after new external toothing, recycling connecting pin retightens core wheel and external toothing to link into an integrated entity, and compares with the gear that integral replacing in prior art is new, greatly save material, reduced locomotive maintenance cost.
