Abstract
The utility model discloses a plum-blossom type elastic coupling which comprises a driving coupling band (1), a driven coupling band (2) and an elastomer (3), wherein the driving coupling band (1) and the driven coupling band (2) are connected by the elastomer (3), fluted discs are arranged at one ends of the driving coupling band (1) and the driven coupling band (2), a plurality of jaw-shaped teeth (5) are uniformly distributed on the inside periphery of each fluted disc, a driving shaft hole (6) is arranged in the middle of the other end of the driving coupling band (1), a driven shaft hole (7) is arranged in the middle of the other end of the driven coupling band (2), and the elastomer (3) takes the shape of an involute plum blossom. The plum-blossom type elastic coupling has the following benefits: the elastic coupling has failure protection function, can reduce vibration and impact generated in the running process, and also can effectively correct axial, radial and angular installation deviation; the drum-type involute teeth of the elastomer can realize higher eccentric load and deflected load; and the elastic coupling has higher torque wearability and longer service life.
Description
Technical field
It is coupling, particularly blossom type elastic coupling flexible coupling in the transmission that the utility model relates to a kind of mechanical axis.
Background technique
Coupling is two axles (driving shaft and driven shaft) that are used for connecting in the different institutions, make it together to rotate the also component of machine of transmitting torque, general power engine links by means of coupling and working machine, and coupling generally is made up of two halves, connects with driving shaft and driven shaft respectively.
The plum blossom coupling is a kind of very universal coupling, also be paul pawl coupling, be that two metal claw dishes and an elastomer are formed, but existing elastomer can not be handled very big axial deviation, so that bigger off-centre and drift angle produce bigger bearing load, and existing plum blossom partition adjustable body bears bending force and pressure wearing and tearing or inefficacy easily, in case after wearing and tearing or the inefficacy, the moment of torsion transmission can't be interrupted, the pawl of two axle sleeves meshes together the continuation transmitting torque simultaneously, and this causes system to go wrong easily.
The model utility content
The purpose of this utility model promptly is to overcome the shortcoming of prior art, a kind of plum blossom elastic coupling flexible coupling that physical dimension is little, in light weight, transmitting torque is high that has is proposed, it has fail protection function, effectively vibration and the impact that is produced in damping and the minimizing running; The elastomer of plum blossom elastic coupling flexible coupling only bears pressure, thereby can bear bigger load, and the life-span is longer.
The purpose of this utility model is achieved through the following technical solutions: the blossom type elastic coupling flexible coupling, it comprises main coupling band, from coupling band and elastomer, main coupling band be connected by elastomer from coupling band, main coupling band and be equipped with fluted disc from an end of coupling band, the fluted disc inside circumference all is evenly distributed with several claw type teeth, two inner side surfaces of claw type tooth are curved surfaces, in the middle of the main coupling band the other end, be provided with spindle hole, in the middle of the other end of coupling band, be provided with from axis hole, elastomer is the quincunx elastomer of involute, its inboard is provided with axis hole, is evenly distributed with some crowned teeths on the outer circumference.
Described main coupling band and from the claw type tooth of the coupling band half tooth distance that staggers mutually in a circumferential direction.
Described half tooth is apart from being complementary with elastomeric crowned teeth tooth pitch.
The beneficial effects of the utility model show: the blossom type elastic coupling flexible coupling has fail protection function, effectively vibration and the impact that is produced in damping and the minimizing running; It can effectively correct axially, radially with the installation deviation of angle; Its elastomeric drum type involute tooth can be realized bigger off-centre and drift angle load, and the moment of torsion wear resistance is higher, and the life-span is longer.
