Background
A coupling is a device used to couple two shafts of different machines for rotation together to transmit torque and motion. The couplings of the prior art mainly comprise a rigid coupling and a flexible coupling, wherein the flexible coupling is more widely used in mechanical devices due to its compensation capability. Flexible couplings include couplings without resilient elements and couplings with resilient elements, where couplings with resilient elements are more suitable for low load operating environments. The coupling with the elastic element mainly comprises a metal elastic element coupling and a rubber elastic element coupling.
The metal elastic element coupler comprises a high damping reed coupler, and can refer to a Chinese utility model 'large torque reed type full compensation elastic coupler' with the publication number of CN 204592052U; film disc couplings, reference may be made to chinese utility model multi-curvature film disc couplings, publication No. CN105179503 a; the laminated diaphragm coupling can refer to a Chinese utility model 'high softness diaphragm flexible coupling' with the bulletin number of CN 201513481U; serpentine spring couplings, reference is made to the chinese utility model "serpentine spring coupling" of CN205207467U, and others. However, the metal elastic element couplings commonly used in the prior art have complicated structures, and the cost for manufacturing the elastic element by adopting metal is high.

However, the rubber elastic element couplings commonly used in the prior art are also relatively complex in structure, and the service lives of the couplings are relatively short due to the failure of rubber.
And, the above-mentioned two kinds of elastic element couplings are assembled into the whole coupling first and then assembled with the drive shaft for use, just have to demolish the apparatus and install again when meeting narrow and small installation space. Therefore, there is a need for a flexible coupling that is simple in construction, low in cost, long in service life, and can be applied to a relatively small installation space.

In order to obtain better supporting force and elasticity and reduce cost, the flexible piece is made of engineering plastics.

Detailed Description
The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples.
As shown in fig. 1 to 4, the flexible coupling comprises a first half coupling 1 with a first shaft hole 111 and a second half coupling 2 with a second shaft hole 211 which are oppositely arranged, and a flexible piece 3 positioned between the first half coupling 1 and the second half coupling 2, wherein through holes 31 corresponding to the first shaft hole 111 and the second shaft hole 211 are arranged in the middle of the flexible piece 3 (when the first shaft hole 111 and the second shaft hole 211 are internally provided with corresponding first transmission shafts and second transmission shafts, the first transmission shafts and the second transmission shafts can extend into the through holes 31 and can adjust the positions of the flexible piece 3 according to requirements), the periphery of the flexible piece 3 is provided with an even number of first elastic connecting arms 32 extending along the circumferential clockwise direction, and second elastic connecting arms 33 extending along the circumferential anticlockwise direction, and the second elastic connecting arms 33 are arranged in one-to-one symmetry with the first elastic connecting arms 32; the first half coupling 1 and the second half coupling 2 are respectively provided with a first connecting piece 321 which can be detachably connected with the first elastic connecting arm 32 and a second connecting piece 331 which can be detachably connected with the second elastic connecting arm 33, the two first connecting pieces 321 corresponding to any two adjacent first elastic connecting arms 32 are respectively positioned on the first half coupling 1 and the second half coupling 2 (namely respectively positioned on different half couplings), the two second connecting pieces 331 corresponding to any two adjacent second elastic connecting arms 32 are respectively positioned on the first half coupling 1 and the second half coupling 2 (namely respectively positioned on different half couplings), the first connecting pieces 321 and the second connecting pieces 331 corresponding to the first elastic connecting arms 32 and the second elastic connecting arms 33 which are symmetrical with each other are respectively positioned on the first half coupling 1 and the second half coupling 2 (namely respectively positioned on different half couplings), and preferably, the two second connecting pieces 331 corresponding to the first elastic connecting arms 321 and the second elastic connecting pieces 33 which are symmetrical with each other are also positioned on the first connecting pieces 331 corresponding to the first elastic connecting pieces 33 and the second elastic connecting pieces 33 which are mutually symmetrical. The first coupling half 1, the second coupling half 2, the first connecting member 321 and the second connecting member 331 of the present embodiment are all made of aluminum alloy, but other suitable metals or alloy materials may be used.
In order to facilitate assembly, the first connecting piece 321 and the second connecting piece 331 are connecting pins, and the first elastic connecting arm 32 and the second elastic connecting arm 33 are provided with a first connecting hole 322 and a second connecting hole 332 for inserting corresponding connecting pins. In order to facilitate alignment of the connectors with the corresponding connecting holes during assembly, the first elastic connecting arm 32 and the second elastic connecting arm 33 of the present embodiment have a symmetry axis a on the flexible member 3, the first elastic connecting arm 32 is located at one side of the symmetry axis a, and the second elastic connecting arm 33 is located at the other side of the symmetry axis a. In addition to this, the following means can be used to provide the spring connection arm: a second resilient connecting arm 33 is arranged between two adjacent first resilient connecting arms 32. In order to make the structure of the flexure 3 more compact and easy to assemble, the first elastic connection arm 32 and the second elastic connection arm 33 of the present embodiment are each provided with two.
In order to make the first elastic connection arm 32 and the second elastic connection arm 33 not easily broken, the first connection hole 322 and the second connection hole 332 are provided at the free ends of the corresponding first elastic connection arm 32 and second elastic connection arm 33. In this way, when the two coupling halves are offset by a certain distance, the torsion degree of the first elastic connecting arm 32 and the second elastic connecting arm 33 is smaller and the coupling halves are less likely to break relative to the scheme that the connecting hole is provided at the position far away from the free end on the connecting arm.
For easy assembly with the drive shaft, the first coupling half 1 is provided with a first gap 11 extending radially from the first shaft hole 111 to an opening; the second coupling half 2 is provided with a second gap 21 extending radially from the second shaft hole 211 to form an opening; the first half coupling 1 and the second half coupling 2 are respectively provided with a locking piece 6, and two side walls of the first gap 11 and the second gap 21 are penetrated and matched by the locking pieces 6 respectively, so that the sizes of the first gap 11 and the second gap 21 can be changed by the locking pieces 6. The locking member 6 of the embodiment is a bolt, and one side wall of the first gap 11 and the second gap 21 is provided with a through hole 61; the other side walls of the first gap 11 and the second gap 21 are provided with threaded holes 62 coaxially distributed with the through holes 61, and the bolts pass through the through holes 61 and then are in threaded fit with the threaded holes 62. Besides, the feasible scheme is as follows: the locking piece 6 is a bolt, and a locking nut is arranged at the tail end of the bolt after passing through the corresponding half coupling. Besides, the scheme is as follows: the retaining member 6 is a screw rod with opposite screw thread directions at two end parts, a first threaded hole is formed in one side wall of the first gap 11 and one side wall of the second gap 21, a second threaded hole which is coaxially distributed with the first threaded hole is formed in the other side wall of the first gap 11 and the other side wall of the second gap 21, the inner threads of the second threaded hole and the first threaded hole are opposite in rotation direction, two end parts of the screw rod are respectively in threaded connection with the first threaded hole and the second threaded hole, and therefore the two side walls of the first gap 11 and the two side walls of the second gap 21 can be relatively close to each other or far away from each other by rotating the screw rods. In order to prevent the transmission shaft penetrating through the through hole 31 from radially shifting to collide with the inner wall of the through hole 31 during rotation, the aperture of the through hole 31 in this embodiment is larger than the aperture of any one of the first shaft hole 111 and the second shaft hole 211.
In order to prevent the eccentricity of the first half coupling 1 and the second half coupling 2 during rotation, a weight groove 7 for balancing the first gap 11 is provided on the first half coupling 1; a weight groove 7 for balancing the second gap 21 is provided in the second coupling part 2. The weight slot 7 of the present embodiment is annular, and the center of the annular ring is concentric with the centers of the corresponding first shaft hole 111 and second shaft hole 211.
In order to enable the flexible member 3 to have a certain supporting force and proper elasticity at the same time, the flexible member 3 is made of engineering plastics. The engineering plastic can be any one of polyurethane, polyamide, polycarbonate and other suitable materials. Moreover, the flexible piece 3 of the utility model is made of engineering plastic materials, so that the defect of preparing the flexible piece 3 by adopting rubber materials can be avoided: rubber is easily affected by working environment, has poor heat resistance and oil resistance, is easy to age and deteriorate, has low strength and poor bearing capacity; the defect of using metal materials to prepare the flexible piece 3 can also be avoided: the cost is high and it is difficult to obtain a complex structure (it is difficult to process a metal material into the shape of the flexible member 3 of the present utility model).
As shown in fig. 3 or 4, the flexible coupling is assembled by first inserting the first connecting member 321 and the second connecting member 331 of one coupling half into the corresponding first connecting hole 322 and the second connecting hole 332 of the flexible member 3, and then inserting the first connecting member 321 and the second connecting member 331 of the other coupling half into the remaining corresponding first connecting hole 322 and second connecting hole 332.
When the flexible coupling is mounted on a transmission shaft, the coupling is firstly disassembled into a first half coupling 1, a second half coupling 2 and a flexible part 3, so that the volume of each part is smaller, the flexible coupling can be applied to a mounting environment with a smaller gap between the transmission shafts at two ends of the coupling, and only the first half coupling 1 and the second half coupling 2 are sleeved on the corresponding first transmission shaft and the second transmission shaft through corresponding first shaft holes 111 and second shaft holes 211, and the flexible part 3 is sleeved on one transmission shaft through a through hole 31; then, the positions of the first half coupler 1, the second half coupler 2 and the flexible piece 3 are moved to proper positions along the axial direction, and the corresponding first connecting piece 321 and second connecting piece 331 are inserted into the corresponding first connecting hole 322 and second connecting hole 332 on the first elastic connecting arm 32 and the second elastic connecting arm 33; and then the locking piece 6 is screwed into the through hole 61 and the threaded hole 62 in sequence, and the corresponding first gap 11 or the second gap 21 is contracted, so that the corresponding half coupling and the corresponding transmission shaft can be fastened and connected.
In the rotation process of the transmission shaft, the first elastic connecting arm 32 and the second elastic connecting arm 33 can be elastically deformed along with displacement deviation between the two half couplings, such as bending, torsion and the like, and the first elastic connecting arm 32 and the second elastic connecting arm 33 respectively extend clockwise and anticlockwise and have the capability of recovering after elastic deformation, so that the flexible coupling can absorb axial displacement, radial displacement and angular displacement between the two half couplings in a smaller range and has the aligning capability. Therefore, the flexible coupling is suitable for working environments with lower rotating speed, lower load and smaller offset between transmission shafts at two ends of the coupling during rotation, and meanwhile, the installation space is narrower. For example, the encoder may be used to connect an encoder rotor and a power source rotor, and the connection structure of the encoder and the power source in the prior art may refer to the chinese utility model with publication number CN205605674U, namely, the connection structure of the encoder and the power source, i.e. replace the rigid coupling on the structure: an Oldham coupling.
The coupler has a simple structure, and greatly reduces the manufacturing cost; moreover, the rubber which is easy to lose efficacy is not used, so that the long-term stable working state can be maintained; the cost is further reduced by not using metal for the flexure 3.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
