Utilize the trip in the upper flange to inlay the cooperation with the draw -in groove in the lower flange to the upper flange be in the same place with lower flange fastening connection, and when motor and gear box transmission, the relation of closely cooperating of two protruding pieces of flange utilization and recess reduces not hard uply, avoids the bolt fracture, phenomenon that the security performance is not high, and through resilient means, the vibration in the process of rotation weakens to the diaxon, guarantees indirectly that the diaxon to neutrality, causes the additional load in the reduction parts, the life of improvement shaft coupling.
Description
Technical field
The utility model relates to a kind of coupling technical field, especially flange coupling.
Background technique
Flange coupling is used to the bindiny mechanism connecting motor and gear-box, belongs to rigid coupling.
Flange coupling is that two half-couplings with flange are connected with diaxon respectively with parallel key, then with bolt, two half-couplings is connected, to transmit motion and torque.
Due to motor and gearbox drive, easily make two flange members loosen, finally cause bolt fracture, Safety performance is not high.Flange coupling is very high to the requirement of diaxon centering, when diaxon has relative displacement to exist, will cause additional load in parts, working condition is worsened, and reduces the working life of coupling.
Summary of the invention
For the deficiencies in the prior art, the utility model provides flange coupling, include upper flange and lower protruding edge, described upper flange end face is provided with protruding block by the quartering, in described protruding block, there is draw-in groove, the end face of described lower protruding edge is provided with groove by the quartering, in described groove, be formed with snap fit, described draw-in groove matches with described snap fit, and described lower protruding edge is formed with elastic device.
Further, described upper flange end face is formed with upper bolt hole by the quartering, described lower protruding edge end face is formed with lower bolt hole by the quartering, described upper bolt hole and described protruding block are interspersed, and described lower bolt hole and described groove are interspersed.
Further, described lower protruding edge is formed with several mounting holes, described elastic device is arranged in described mounting hole.
Further, described elastic device comprises flexible block and spring, and described flexible block is connected on described spring, and described spring fitting is in described mounting hole.
Further, described flexible block is connected on described spring by welding manner.
The beneficial effects of the utility model are: utilize the snap fit in upper flange to inlay with the draw-in groove in lower protruding edge and coordinate, thus upper flange and lower protruding edge are fastened together, when motor and gearbox drive, two flanges utilize the close-fitting relationship minimizing of protruding block and groove to loosen, avoid bolt fracture, the phenomenon that Safety performance is not high, pass through elastic device, the vibration of diaxon at rotation process is weakened, indirect guarantee diaxon centering, reduce in parts and cause additional load, improve the working life of coupling.
Accompanying drawing explanation
The flange shaft coupling cut-away illustration that Fig. 1 provides for the utility model embodiment.
In figure, 101 is upper flange, and 1011 is protruding block, and 1012 is draw-in groove, and 1013 is upper bolt hole, and 102 is lower protruding edge.1021 is groove, and 1022 is snap fit, and 1023 is lower bolt hole, and 103 is elastic device, and 1031 is flexible block, and 1032 is spring.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the preferred embodiment that provides of the utility model.
Flange coupling, include upper flange 101 and lower protruding edge 102, wherein, tightr in order to make to be connected between upper flange 101 with lower protruding edge 102, upper flange 101 end face is provided with protruding block 1011 by the quartering, there is in protruding block 1011 draw-in groove 1012, the end face of lower protruding edge 102 is provided with groove 1021 by the quartering, snap fit 1022 is formed in groove 1021, draw-in groove 1012 matches with snap fit 1022, lower protruding edge 102 is formed with elastic device 103, plays a part to absorb the vibration force produced in diaxon rotation process.
After snap fit 1012 is embedded draw-in groove 1022, realize the connection of two flanges, when diaxon operates, vibration can be produced to two flanges, also the centering of diaxon can be caused to produce skew, and at this moment, produced vibration force weakens by elastic device, be converted into the elastic strain of self, indirectly ensure that the centering of diaxon does not offset.
Utilize the draw-in groove 1012 in upper flange 101 to inlay with the snap fit 1021 in lower protruding edge 102 to coordinate, thus upper flange 101 and lower protruding edge 102 are fastened together, when motor and gearbox drive, two flanges utilize the close-fitting relationship minimizing of projection and groove to loosen, avoid bolt fracture, the phenomenon that Safety performance is not high, in addition, elastic device can be passed through, the vibration of diaxon at rotation process is weakened, indirect guarantee diaxon centering, reduces in parts and causes additional load, improves the working life of coupling.
Particularly, upper flange 101 end face is formed with upper bolt hole 1013 by the quartering, lower protruding edge 102 end face is formed with lower bolt hole 1023 by the quartering, upper bolt hole 1013 and protruding block 1011 are interspersed, and lower bolt hole 1023 is interspersed with groove 1021.Except with except the inlaying and be connected of little groove 1012 and small lugs 1022, bolt hole is also adopted to be connected by two flanges, when flange occurs to loosen, if after bolt is cut off, two flanges can also utilize little recessed 1012 grooves to keep being connected with inlaying of small lugs 1022, so that staff need not align to two flanges when again going up bolt next time, convenient and structure is simple.
Lower protruding edge 102 is formed with several mounting holes, elastic device 103 is arranged in mounting hole, absorbed because diaxon rotates the vibration force produced between upper flange and lower protruding edge by the elastic device 103 in lower protruding edge, indirect guarantee diaxon centering, reduce in parts and cause additional load, improve the working life of coupling.
Particularly, elastic device 103 comprises flexible block 1031 and spring 1032, flexible block 1031 is connected on spring 1032, spring 1032 is arranged in mounting hole, because diaxon rotates, the elastic strain of spring 1032 will be converted into the vibration force produced between upper flange and lower protruding edge, reduce in parts and cause additional load, improve the working life of coupling.。
Flexible block 1031 is connected on spring 1032 by welding manner, certainly, in practice, other Placements can be adopted flexible block 1031 and spring 1032 to be linked together, be not limited to welding manner.
What describe in above-described embodiment and specification just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
