Abstract
The utility model provides a wedge-caulking element and a main reducing gear clutch with the same, wherein the wedge-caulking element comprises a first cam arc working surface (1) and a second cam arc working surface (2), and a first chamfer part (3) is disposed respectively at both ends of the first cam arc working surface (1). The wedge-caulking element performs unloading effectively for high stress centralized areas so that the problem of breakage of both ends of the wedge-caulking element is avoided.
Description
Technical field
The utility model relates to the main reducing gear clutch field, in particular to a kind of wedging element and the main reducing gear clutch with this wedging element.
Background technique
Wedging element two ends fracture defect frequently appears in the main reducing gear clutch in stand test.Because the straightness accuracy of the wedging element that this kind is elongated difficulty reaches designing requirement, under excessive stress, ruptures easily.Generally take at present the straightness accuracy of strict control wedging element work arc surface; The wedging element carries out processing processing wedging elements such as surface treatment, secondary quenching behind the fluting earlier again to the wedging element.
Experimental analysis shows; There is local heavily stressed contact area in the two ends of the inside and outside cam circular arc working surface of elongated wedging element under normal operation; In production and processing, on the one hand because the surface-treated furnace temperature is higher, and the voussoir length dimension is compared longer relatively with cross-sectional dimension; Slot owing to some wedging element two ends on the other hand; The wall thickness at two ends is thin than intermediate portion; Thereby the straightness accuracy of the vertical profile of wedging element is difficult to meet design requirement; Especially wedging element two ends are prone to produce warpage after surface treatment, can increase the weight of the stress of heavily stressed contact area in the wedging element work of warpage and concentrate, thereby cause clutch frequently to occur wedging element two ends fracture defect in the course of the work.
The model utility content
The utility model aims to provide a kind of wedging element and the main reducing gear clutch with this wedging element, and the problem that ruptures in wedging element two ends frequently appears in clutch in the course of the work in the existing technology to solve.
To achieve these goals, an aspect according to the utility model provides a kind of wedging element, comprises the first cam circular arc working surface and the second cam circular arc working surface, and the two ends of the first cam circular arc working surface are equipped with first chamfered section.
Further, the two ends of the second cam circular arc working surface are equipped with second chamfered section.
Further, first chamfered section and second chamfered section are the straight line chamfered section.
Further, the chamfer dimesion of straight line chamfered section is 3～5mm * 0 ° 45 '.
Further, first chamfered section and the first cam circular arc working surface are arc transition, and second chamfered section and the second cam circular arc working surface are arc transition.
Further, the material of wedging element is a high hardness alloy steel.
According to the utility model on the other hand, a kind of main reducing gear clutch is provided, has had above-mentioned wedging element.
The technological scheme of the utility model is equipped with chamfered section at the edge, two ends of the first cam circular arc working surface and the second cam circular arc working surface; During clutch work is high stress areas here; Chamfered section is that the profile of straight line can effectively unload stress than bus, thereby has solved the problem of wedging element two ends fractures.
Description of drawings
The Figure of description that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is first embodiment's the structural representation of the wedging element of the utility model; And
Fig. 2 is second embodiment's the structural representation of the wedging element of the utility model.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the utility model.
Fig. 1 shows first embodiment according to a kind of wedging element of the utility model; Wedging element among this embodiment comprises the first cam circular arc working surface 1 and the second cam circular arc working surface 2; Wherein, the two ends of the first cam circular arc working surface 1 are equipped with first chamfered section 3; (the straight line chamfered section is meant along straight line and carries out chamfering first chamfered section 3 here for the straight line chamfered section in the present embodiment; Rather than carry out chamfering) along curve; Because the both sides of the first cam circular arc working surface 1 have fluting portion 11; So the edge of the first cam circular arc working surface 1 is a high stress areas when clutch is worked, first chamfered section 3 is that the profile of straight line can effectively unload stress than bus, thereby has solved the problem of wedging element two ends fractures.Preferably, the material of wedging element is a high hardness alloy steel, is meant the alloyed steel of hardness greater than HRC60 specifically, and for example the alloyed steel of hardness in the HRC61-65 scope is best.Simultaneously, on manufacturing procedure, be to improve the yield rate of product, need adjustment wedging element manufacturing procedure, operation is adjusted into carries out surface treatment earlier, carry out secondary quenching, processings of slotting at last again, thereby eliminate root place stress raisers behind the fluting.
Fig. 2 shows second embodiment according to a kind of wedging element of the utility model; Be that with first embodiment's difference the shape of wedging element is different, in the present embodiment, the both sides of the first cam circular arc working surface 1 and the second cam circular arc working surface 2 all have fluting portion; So in a second embodiment; The two ends of the first cam circular arc working surface 1 are equipped with first chamfered section 3, and simultaneously, the two ends of the second cam circular arc working surface 2 also are equipped with second chamfered section 4.The effect of second chamfered section 4 is identical with the effect of first chamfered section 3, and preferably, in a second embodiment, second chamfered section 4 also is the straight line chamfered section.
For chamfer dimesion, preferably, the chamfer dimesion of first chamfered section 3 and second chamfered section 4 is 3～5mm * 0 ° 45 ' the best.In order better to unload stress, preferably, first chamfered section 3 and the first cam circular arc working surface 1 are arc transition, and second chamfered section 4 and the second cam circular arc working surface 2 are arc transition.Reduce the possibility that stress is concentrated.
The utility model also provides a kind of main reducing gear clutch, comprises above-mentioned wedging element.The main reducing gear clutch that adopts above-mentioned wedging element is owing to the fracture of having avoided the wedging element causes fault, thereby working stability is strong, good reliability.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
