According to the utility model, the repairing groove is machined in the shaft end surface of the original shaft, the connecting step matched with the repairing groove in shape is correspondingly machined in the repairing shaft supplemented later, finally, the connecting step is embedded in the repairing groove and is fastened through screw threads; the broken shaft repairing structure can be used for repairing broken shafts with bigger shaft diameters and higher coaxiality of the entire repaired shaft.
Description
Technical field
The utility model relates to the machinery maintenance field, especially a kind of off-axis repair structure.
Background technique
Machinery take speed reducer as representative, its transmission shaft plays a part input power.Transmission shaft situation about rupture because of tired may occur in use for some time, and causes thus the machinery such as speed reducer can't continue use.
In the face of this kind situation, if can't find the axle that is complementary with it, then whole speed reducer equipment is namely scrapped, and this can cause very large waste, directly increases operation cost of enterprises.If connect the part of breaking and the transmission shaft that breaks keeped in repair and mend, traditional repairing method is difficult to again guarantee to repair the coaxality of rear whole section axle, causing the axle that obtains after the effort maintenance also can't use, and the wasting manpower and material resources.
The model utility content
Technical problem to be solved in the utility model provides a kind of off-axis repair structure that can guarantee whole section axle coaxality after off-axis is repaired.
The technological scheme that its technical problem that solves the utility model adopts is: the off-axis repair structure, comprise primitive axis, and be connected with primitive axis and with the prosthesis shaft of the axis conllinear of primitive axis, be provided with the connected unit coaxial with described prosthesis shaft on the end face of prosthesis shaft, primitive axis is provided with the reparation groove that is complementary with described connected unit shape near on the primitive axis axial end of prosthesis shaft one end, and repair groove and primitive axis coaxial line, described connected unit is fixedly installed on repairs in the groove.
Further be, connected unit is comprised of circular cone and cylinder, and the bottom surface of cylinder is connected with the end face of prosthesis shaft.
Further be to be provided with the primitive axis groove on the excircle of described primitive axis axial end.
Further be to be provided with the prosthesis shaft groove on the excircle of described prosthesis shaft near the end face of primitive axis.
Further be to be provided with scolder between primitive axis groove and the prosthesis shaft groove.
Further be to be threaded connection between connected unit and the reparation groove.
The beneficial effects of the utility model are: after formerly using machined into smooth the irregular end face of primitive axis, process the reparation groove in the primitive axis axial end that newly processes, and machining internal thread in groove, and on the prosthesis shaft that replenishes afterwards also corresponding processing and the connected unit of repairing groove shapes and being complementary, and threading on connected unit, the outside thread with connected unit is screwed into fastening the getting final product of reparation groove internal thread at last.Because described primitive axis, the axis of repairing groove, connected unit, prosthesis shaft all are conllinear, just well guaranteed the coaxality of whole section axle finally obtaining.This processing structure operation is comparatively easy, and effect is more satisfactory.It is larger that the utility model can be applied to repair the diameter of axle, and the higher off-axis of coaxality to repairing rear whole section axle.
Description of drawings
Fig. 1 is the schematic representation of primitive axis.
Fig. 2 is the schematic representation of prosthesis shaft.
Fig. 3 is the schematic representation after reparation is finished in primitive axis and prosthesis shaft cooperation.
Be labeled as among the figure: primitive axis 1, primitive axis axial end 11, primitive axis groove 111, reparation groove 112, prosthesis shaft 2, prosthesis shaft groove 21, connected unit 22.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Such as Fig. 1, Fig. 2 and off-axis repair structure shown in Figure 3, comprise primitive axis 1, and be connected with primitive axis 1 and with the prosthesis shaft 2 of the axis conllinear of primitive axis 1, be provided with the connected unit 22 coaxial with described prosthesis shaft 2 on the end face of prosthesis shaft 2, primitive axis 1 is provided with the reparation groove 112 that is complementary with described connected unit 22 shapes near on the primitive axis axial end 11 of prosthesis shaft 2 one ends, and repair groove 112 and primitive axis 1 coaxial line, described connected unit 22 is fixedly installed on repairs groove interior 112.
The primitive axis 1 that interrupts falling take speed reducer is as example, and is in actual production, first that the section of primitive axis 1 is smooth with machined into.Be on the primitive axis axial end 11 on the smooth plane of new processing, process the reparation groove 112 with primitive axis 1 coaxial line, such reparation groove 112 utilizes machined into relatively more convenient, also can well guarantee to repair the central axis of groove 112 and the axis conllinear of primitive axis 1.Simultaneously, choose the diameter of axle greater than with the shaft part of primitive axis 1 as prosthesis shaft 2, and at the end face of prosthesis shaft 2 connected unit 22 coaxial with described prosthesis shaft 2 is set.Wherein, the shape of connected unit 22 need to be complementary with the shape of repairing groove 112, guarantees that connected unit 22 can be embedded in the reparation groove 112.At last, need to fastening between connected unit 22 and the reparation groove 112, allow primitive axis 1 and prosthesis shaft 2 be fastenedly connected as a whole and the assurance coaxality.
In order to simplify the shape of connected unit 22, make things convenient for processing and fabricating, the shape of connected unit 22 can be designed as by circular cone and cylinder and forms, and the bottom surface of cylinder is connected with the end face of prosthesis shaft 2.Connected unit 22 shapes as shown in Figure 2 can utilize lathe to process easily, and can well guarantee to be embedded into the coaxality of repairing groove 112 rear whole section axles.
In order to reinforce the connection between primitive axis 1 and the prosthesis shaft 2, be provided with primitive axis groove 111 on the excircle of described primitive axis axial end 11.It is for after finishing connection that primitive axis groove 111 is set, and can strengthen connection between primitive axis 1 and the prosthesis shaft 2 by welding manner, and the scolder during welding is just in the breach of primitive axis groove 111.
Same, be provided with prosthesis shaft groove 21 on the excircle of described prosthesis shaft 2 near the end face of primitive axis 1, also be for storing scolder.
Unification based on above-mentioned two schemes, when primitive axis groove 111 and prosthesis shaft groove 21 all exist, be provided with scolder between primitive axis groove 111 and the prosthesis shaft groove 21, this scheme also can use primitive axis groove 111 and prosthesis shaft groove 21 to be used for storing scolder, strengthens the connection of two sections axles.
In order to strengthen connected unit 22 and to repair being connected between the groove 112, can repair the screw thread that processes cooperation on groove 112 inwalls, connected unit 22 outer walls, whole section axle played larger fastening effect.
In order to make the external diameter of the axle after the reparation that obtains at last identical everywhere, can select the initial circumference external diameter of prosthesis shaft 2 greater than primitive axis 1 circumference external diameter.Built-up welding material between primitive axis groove 111 and prosthesis shaft groove 21, until after the same with the initial circumference external diameter of prosthesis shaft 2, the scolder between lathe car bits prosthesis shaft 2 and primitive axis groove 111 and prosthesis shaft groove 21 again, until the circumference external diameter that obtains prosthesis shaft 2 and primitive axis 1 the circumference external diameter is the same gets final product.
