Abstract
The utility model relates to a kind of transmission shaft connecting structure, comprises main shaft, is arranged on the spindle flange of main shaft connecting end, auxiliary axle and is arranged on the auxiliary shaft flange of auxiliary axle connecting end; The junction surface of described spindle flange is provided with Flange joint boss, and the junction surface of described auxiliary shaft flange is provided with Flange joint groove; Described Flange joint boss inserts in described Flange joint groove, and both can not coordinate with the relative rotation, and described spindle flange and auxiliary shaft flange are connected by screw axial restraint.Compared with prior art, owing to being no longer by screw in the transmission of spindle flange and auxiliary shaft flange, but realized with mating of groove by boss, therefore screw almost no longer bears shearing stress, just axial restraint is carried out to both, thus effectively guarantee transmission and the machine breakdown of main and auxiliary axle.
Description
Technical field
The utility model relates to non-standard automatic apparatus field, especially a kind of transmission shaft connecting structure.
Background technique
In existing non-standard automatic equipment, spindle flange to be mainly fixedly connected with auxiliary shaft flange by screw by shaft drive carries out transmission, but due to when transmission, the screw connecting two flanges bears very large shearing stress, time is permanent, screw can therefore fracture damage, then can cause damage to complete machine, brings economic loss and greatly affect manufacturing efficiency for factory.
Model utility content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of transmission shaft connecting structure.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of transmission shaft connecting structure, is characterized in that: comprise main shaft, be arranged on the spindle flange of main shaft connecting end, auxiliary axle and be arranged on the auxiliary shaft flange of auxiliary axle connecting end; The junction surface of described spindle flange is provided with Flange joint boss, and the junction surface of described auxiliary shaft flange is provided with Flange joint groove; Described Flange joint boss inserts in described Flange joint groove, and both can not coordinate with the relative rotation, and described spindle flange and auxiliary shaft flange are connected by screw axial restraint.
Compared with prior art, owing to being no longer pass through screw in the transmission of spindle flange and auxiliary shaft flange, but realized with mating of Flange joint groove by Flange joint boss, therefore screw almost no longer bears shearing stress, just axial restraint is carried out to both, thus effectively guarantee the transmission of main and auxiliary axle and machine not fragile.
Further, the shape of described Flange joint boss and Flange joint groove is polygonal, D font.
Preferably, the both sides of Flange joint boss are provided with symmetrical flat position, and described Flange joint groove is provided with the limited wall matched with described flat position, increase the lifting surface area of Flange joint boss and Flange joint groove, guarantee effective transmission of main shaft and auxiliary axle.
Further, more easily assemble in order to ensure main shaft and spindle flange and locate, main shaft connecting groove is provided with in one end that spindle flange is connected with main shaft, the connecting end of described main shaft is provided with main shaft connection bump, described main shaft connection bump is inserted in described main shaft connecting groove, and both can not coordinate with the relative rotation, described spindle flange and main shaft are welded and fixed.
Further, because main shaft welds with spindle flange, therefore when long-time transmission, the joint of main shaft and spindle flange can easy break apart, in order to ensure the two not easy-rupturing separation, the shape that main shaft connects boss and main shaft connecting groove is polygonal, D font.
Preferably, the both sides that main shaft connects boss are provided with symmetrical flat position, and described main shaft connecting groove is provided with the limited wall matched with described flat position.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model sectional view;
Fig. 3 is the assembling schematic diagram of the utility model main shaft and spindle flange.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, transmission shaft connecting structure of the present utility model, comprises main shaft 1, is arranged on the spindle flange 2 of main shaft 1 connecting end, auxiliary axle 3 and is arranged on the auxiliary shaft flange 4 of auxiliary axle connecting end; The junction surface 23 of described spindle flange 2 is provided with Flange joint boss 21, and the junction surface 42 of described auxiliary shaft flange 4 is provided with Flange joint groove 41; Described Flange joint boss 21 inserts in described Flange joint groove 41, and both can not coordinate with the relative rotation, such as the shape of Flange joint boss 21 and Flange joint groove 41 is set to polygonal or D font, preferably, the both sides of Flange joint boss 21 are set to symmetrical flat position, described Flange joint groove 41 is provided with the limited wall 211 matched with described flat position, increases Flange joint boss 21 and the lifting surface area of Flange joint groove 41, guarantees effective transmission of main shaft and auxiliary axle.Described spindle flange 2 is connected axial restraint with auxiliary shaft flange 4 by screw 5.
As described in Figure 3, in the present embodiment, more easily assemble in order to ensure main shaft 1 and spindle flange 2 and locate, the one end be connected with main shaft 1 at spindle flange 2 is provided with main shaft connecting groove 22, the connecting end 11 of described main shaft 1 is provided with main shaft connection bump 111, described main shaft connects convex 111 and inserts in described main shaft connecting groove 22, and both can not coordinate with the relative rotation, spindle flange 2 and main shaft 1 are by being welded and fixed, but when long-time transmission, the joint of main shaft 1 and spindle flange 2 can easy break apart, in order to ensure the two not easy-rupturing separation, the shape that main shaft connects boss 111 and main shaft connecting groove 22 is preferably set to polygonal or D font, the both sides preferably main shaft being connected boss 111 are provided with symmetrical flat position, described main shaft connecting groove 22 is provided with the limited wall matched with flat position.
Compared with prior art, because the transmission at spindle flange 2 and auxiliary shaft flange 3 is no longer pass through screw, but realized with mating of Flange joint groove 41 by Flange joint boss 21, therefore screw 5 almost no longer bears shearing stress, just axial restraint is carried out to both, thus effectively guarantee the transmission of main and auxiliary axle and machine not fragile.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned mode of execution and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
