The utility model provides a diaphragm coupler.
In an embodiment of the present invention, as shown in fig. 1 to 4, the diaphragm coupling includes:
a first coupling 3 for connecting an input shaft;
a second coupling 4 for connecting an output shaft;
an intermediate joint 1 provided between the first coupling 3 and the second coupling 4, the intermediate joint 1 being connected to the first coupling 3 and the second coupling 4 via an elastic diaphragm 2;
and an anti-compression member 5 connecting the first coupling 3 and the second coupling 4 to fix the first coupling 3 and the second coupling 4 relatively in the axial direction.
In this embodiment, the cross-sectional shape of the first coupling 3 is preferably circular, which is advantageous in reducing the area occupied by the first rotary shaft when rotating. First installation position that is used for connecting the input shaft is seted up to the one end of first shaft coupling 3, and first installation position can set up the pore-forming, also can set up to be the breach, does not do specific restriction here, be convenient for with the input shaft installation and fixed can. For example, when the type of the first mounting position is the first mounting hole 31, the first mounting position is disposed at the center of the first coupling 3. Thus, when the input shaft drives the first coupling 3 to rotate at a high speed, the jumping of the first coupling 3 can be reduced, and the generation of vibration can be reduced. The end face of the first coupling 3, which deviates from the first mounting position, is convexly provided with two first mounting bulges, and the two first mounting bulges are arranged at the edge, close to the end face, of the first coupling 3 at intervals of 180 degrees. The height of the first mounting protrusion is not particularly limited, and the elastic diaphragm 2 may be mounted on the first mounting protrusion with a sufficient space to be deformed. In this way, the first coupling 3 can be elastically deformed when rotated to compensate for eccentricity of the input shaft.
The cross-sectional shape of the second coupling 4 is preferably circular, which is advantageous in reducing the area that the second axis of rotation needs to occupy when rotating. The second installation position that is used for connecting the output shaft is seted up to the one end of second coupling 4, and the second installation position can set up the pore-forming, also can set up to be the breach, does not do specific restriction here, is convenient for install the output shaft and fixed connection can. For example, when the type of the second mounting location is the second mounting hole 41, the second mounting location is disposed at the center of the second coupling 4. Therefore, when the output shaft drives the second coupling 4 to rotate at a high speed, the bouncing of the second coupling 4 can be reduced, and the generation of vibration is reduced. The end face of the second coupling 4, which deviates from the second mounting position, is convexly provided with two second mounting protrusions, and the two second mounting protrusions are respectively arranged at the edge close to the end face of the second coupling 4 at intervals of 180 degrees. The height of the second mounting protrusion is not particularly limited, and the elastic diaphragm 2 may be mounted on the second mounting protrusion with a sufficient space to be deformed. So, elastic deformation can take place when being convenient for second coupling 4 to rotate to the eccentricity of compensation output shaft and output shaft.
The relative both sides terminal surface of middle section 1 is equipped with fixed protruding, and the fixed protruding of both sides all has two, and the interval 180 sets up respectively, and the fixed protruding of middle section 1 both sides is close the edge setting in addition, so, when being connected with elastic diaphragm 2, elastic diaphragm 2 has better deformation space. The number of the elastic membranes 2 is two, and the two elastic membranes are respectively arranged on the fixing bulges at the two sides of the middle section 1. In addition, the fixing protrusion is preferably connected with the adjacent first mounting protrusion or second mounting protrusion at an angle of 90 degrees, so that when the first coupling 3, the second coupling 4, the elastic diaphragm 2 and the intermediate coupling 1 form a diaphragm coupling, the elastic diaphragm 2 can be deformed to the maximum extent due to the non-coaxial axes of the input shaft and the output shaft, thereby compensating for the relative displacement of the first coupling 3 and the second coupling 4. In order to improve the rotating stability of the input shaft and the output shaft, the number of the middle sections 1 and the number of the elastic membranes 2 can be multiple, and the two middle sections 1 are radially connected through the elastic membranes 2, so that the capacity of deformation is favorably improved by connecting the middle sections 1 and the elastic membranes 2, the relative displacement between the output shaft and the input shaft can be further compensated, and the stability of the output shaft and the output shaft is improved.
The cross section of the anti-compression member 5 may be circular, rectangular, or irregular, and the like, and is not limited in particular, and the first coupling joint and the second coupling joint 4 may be limited to be close to or far from each other. For example, when the cross-section of the compression preventing member 5 is formed in a regular triangle shape, both ends of the compression preventing member 5 are connected to the first coupling joint and the second coupling joint, respectively. In this way, the compression preventing member 5 limits the first coupling joint and the second coupling joint 4 from moving toward or away from each other in the axial direction, so as to ensure that the axial interval between the first coupling joint and the second coupling joint 4 is limited in a special situation.
The diaphragm coupling of the utility model is characterized in that one end of a first coupling 3 is connected with an input shaft, one end of a second coupling 4 is connected with an output shaft, and an intermediate joint 1 and an elastic diaphragm 2 are arranged between the first coupling 3 and the second coupling 4. Therefore, the diaphragm coupling can compensate the relative displacement of the input shaft and the output shaft through the elastic deformation of the elastic diaphragm 2, and the coaxiality of the output shaft and the output shaft is improved. In addition, the anti-compression piece 5 is arranged between the first coupling 3 and the second coupling 4, and the anti-compression piece 5 can prevent the first coupling 3 and the second coupling 4 from moving relatively, so that when the first coupling 3 and the second coupling 4 work in special occasions, the first coupling 3 and the second coupling 4 can be prevented from being close to or away from each other along the axial direction, the deformability of the elastic diaphragm 2 in the special occasions is guaranteed, and the stability of the output shaft and the output shaft is improved.
Specifically, as shown in fig. 2 to 4, the anti-compression member 5 is disposed in a strip shape, and one end of the anti-compression member 5 is connected to the first coupling 3 and the other end is connected to the second coupling 4. The anti-compression piece 5 is a memory metal piece.
The shape of the anti-compression member 5 may be a strip or a block, and is not particularly limited as long as a predetermined bending is achieved. For example, when the anti-compression member 5 is in a strip shape, two ends of the anti-compression member 5 are respectively connected to the first coupling 3 and the second coupling 4, and the anti-compression member 5 may be connected to the first coupling 3 and the second coupling 4 in a fixed manner or in a detachable manner, which is not limited herein, and the first coupling 3 and the second coupling 4 may be fixed relatively. When taking place elastic deformation for elastic diaphragm 2, avoid being interfered by prevent compression piece 5, influence elastic diaphragm 2 and take place elastic deformation, prevent compression piece 5 and adopt the memory metal setting, so, prevent that compression piece 5 can warp according to elastic diaphragm 2's deformation, be favorable to promoting elastic diaphragm 2's elastic deformation to guarantee the stability of output shaft and output shaft.
Of course, it should be noted that the memory metal is nitinol. The nickel-titanium alloy has the characteristics of superelasticity, ultralow-temperature automatic recovery, wear resistance, corrosion resistance, high damping, superelasticity and the like, and the use of the nickel-titanium alloy is beneficial to prolonging the service life, improving the output precision and the like.
Further, the diameter-to-length ratio of the compression stopper 5 is 1 to 30 times or more and 1 to 50 times or less. So, when preventing that the diameter of compression spare 5 is less than 1 when 30 times than the length ratio, prevent that the elastic deformation of compression spare 5 can't satisfy the designing requirement, interfere the diaphragm elastic deformation easily to influence the output precision of diaphragm shaft coupling. When the ratio of the diameter to the length of the anti-compression piece 5 is more than or equal to 1 to 50 times, the anti-compression piece 5 is too soft to play an effective anti-compression function, and is not beneficial to use.
As shown in fig. 3 to 4, the middle section 1 is provided with a first through hole 11, and the elastic membrane 2 is provided with a second through hole 21; one end of the compression preventing member 5 is connected to the end surface of the first coupling 3, and the other end passes through the first through hole 11 and the second through hole 21 to be connected to the end surface of the second coupling. The center line of the compression preventing member 5 coincides with the rotational axis of the first coupling 3 and the second coupling 4.
In order to facilitate the connection of the anti-compression element 5 with the first coupling 3 and the second coupling 4, the intermediate joint 1 is provided with a first through hole 11, and the radius of the first through hole 11 needs to be larger than one time of the diameter of the anti-compression element 5. So, when preventing that compression piece 5 when elastic deformation along with elastic diaphragm 2, prevent compression piece 5 and the 11 edge contact of first via hole of middle section 1, cause the fish tail to prevent compression piece 5, so, be favorable to protecting and prevent compression piece 5, promote and prevent compression piece 5's life. The elastic membrane 2 is provided with a second through hole 21, and the radius of the second through hole 21 needs to be larger than the diameter of the anti-compression piece 5 by one time. So, when preventing that compression piece 5 when elastic deformation along with elastic diaphragm 2, prevent the second via hole 21 edge contact of preventing compression piece 5 and elastic diaphragm 2 to avoid 2 marginal fish tails of elastic diaphragm to prevent compression piece 5, so, be favorable to protecting to prevent compression piece 5, promote the life of preventing compression piece 5. In addition, in order to reduce the elastic deformation of the compression preventing member 5 caused by the centrifugal force, the compression preventing member 5 is aligned with the rotation axis of the first coupling 3 and the second coupling 4, so that the elastic deformation of the compression preventing member 5 caused by the centrifugal force can be reduced when the first coupling 3 and the second coupling 4 rotate at a high speed.

The overall shape of the second connecting member 7 may be cylindrical or irregular, and is not particularly limited herein, and only needs to be a connecting medium. The shape of the second mounting hole 41 needs to be the same as the outer contour of the second connector 7, and meanwhile, the second mounting hole 41 can be in clearance fit with the second connector 7 or in interference fit with the second connector 7, and no specific limitation is made here, and only the second connector 7 needs to be fixed.

Thus, when the anti-compression member 5 is mounted in the second mounting hole 41 through the second connector 7, the position of the second connector 7 can be adjusted to adjust the displacement of the anti-compression member 5, and thus, the assembly is facilitated.

So, when first locking piece passed first locking hole 32 fixed first connecting piece 6, because first locking piece needs to have certain pressure to contradict first connecting piece 6 for first deformation groove 62 diminishes, and it is tighter that prevent compression piece 5 is compressed, prevents that compression piece 5 obtains further fixed. Secondly, in order to prevent the first connecting member 6 from being deformed when being fastened, resulting in the compression preventing member 5 being deviated from the rotation center of the first joint 3, the number of the first locking holes 32 is two and the number of the first locking members is two. So, when passing through two second locking holes 42 and relatively pressing first connecting piece 6 through two lock first fastening pieces, first connecting piece 6 is pressed by two first locking pieces, thereby ensuring the coaxiality of compression-proof piece 5 and second coupling 4, and improving the stability during rotation
The second coupling 4 is provided with a second locking hole 42, and the second locking hole 42 penetrates through the second mounting hole 41. The second locking member may be a bolt, a screw, or the like, and is not particularly limited herein, and the second connecting member 7 may be fixed through the second locking hole 42. In order that the compression preventing member 5 can be more stably fixed in the second fixing hole 71, the second deforming groove 72 is formed at an angle to the second locking hole 42. Thus, when the second locking member passes through the second locking hole 42 to fix the second connecting member 7, since the second locking member needs to have a certain pressure to press the second connecting member 7, the second deformation groove 72 becomes small, the compression-preventing member 5 is compressed more tightly, and the compression-preventing member 5 is further fixed. Secondly, in order to prevent the second connecting member 7 from being deformed when being fastened, resulting in the displacement of the compression preventing member 5 from the rotation center of the second coupling 4, the number of the second locking holes 42 is two and are oppositely disposed, and the number of the second locking members is two. So, when passing two second retaining members and pressing second connecting piece 7 firmly relatively through two second locking holes 42, second connecting piece 7 is pressed firmly by two second retaining members to guaranteed the axiality of preventing compression member 5 and second coupling 4, improved the stability when rotatory.
