Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to an easily disassembled and assembled flexible coupling. Background Art

[0002] Flexible coupling is a mechanical connector used to transmit power. It compensates for radial, axial and angular deviations of the shafts installed on both sides through the elastic deformation of the elastic element. It also has the function of mitigating impact and absorbing vibration. When the shafts at both ends of the coupling deviate, the elastic material in the center of the coupling is compressed and deformed, thereby mitigating the deviation and vibration of the shafts. When the shaft transmission torque is reversed, the deformation direction of the coupling elastic component will also be reversed, so that the transmission system can achieve a relatively stable operation state.

[0003] The contact area between the elastomer inside the existing flexible coupling and the claw of the clamping sleeve is insufficient, and the claw and the elastomer will be relatively displaced, causing the coupling to easily produce harsh noises during use and reducing the service life of the elastomer. In addition, the clamping sleeve in the coupling is locked on one side, the inner hole of the clamping sleeve has a small applicable range, and after the coupling has been installed and used for a period of time, the inner hole surface of the coupling will be combined and adhered to the surface of the installation shaft, making the coupling difficult to disassemble.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] This embodiment provides an easily disassembled flexible coupling, which has a wide range of applications and is easy to disassemble.

[0032] Specifically, see Figure 1-Figure 4 A flexible coupling that is easy to disassemble and assemble includes a locking mechanism 1 and a connecting mechanism 2. The locking mechanism 1 is provided with two, and the two locking mechanisms 1 are respectively installed on both sides of the connecting mechanism 2. The two locking mechanisms 1 are respectively used to lock two installation shafts, and the connecting mechanism 2 is used to compensate for the radial, axial and angular deviations of the installation shafts on both sides during power transmission.

[0033] For further information, see Figure 2The locking mechanism 1 includes a sleeve, which includes a circular body 11 and a plurality of claws 12 arranged at one end of the circular body 11 at intervals along the axial circumferential direction of the circular body 11. The inner hole of the circular body 11 is used to lock the mounting shaft. Preferably, the plurality of claws 12 at one end of the circular body 11 are evenly spaced, and the plurality of claws 12 in one locking mechanism 1 are cross-opposed to the plurality of claws 12 in another locking mechanism 1, that is, a gap is formed between two adjacent claws 12 arranged at one end of the circular body 11, and the plurality of claws 12 in one locking mechanism 1 are aligned with the gap between two adjacent claws 12 of the other locking mechanism 1 in sequence to form a cross.

[0034] Preferably, the circular body 11 and the plurality of claws 12 disposed thereon are an integral structure.

[0035] See also Figure 1 The circular body 11 is provided with a gap groove 111 along its height direction. The gap groove 111 penetrates the circular body 11 along the radial direction of the circular body 11, and one end of the gap groove 111 extends to the other end of the circular body 11, and the other end extends along the height direction of the circular body 11, so as to adjust the inner hole diameter of the circular body 11 and expand the application scope of this embodiment.

[0036] For further information, see Figure 3 The locking mechanism 1 also includes a locking screw 13. A through hole 112 is provided on the side surface of the circular body 11. The through hole 112 passes through the gap groove 111. The locking screw 13 is screwed into the through hole 112. During installation, the installation shaft is inserted into the inner hole of the circular body 11, and the locking screw 13 is screwed into the through hole 112. The groove height of the gap groove 111 is gradually reduced, thereby locking the installation shaft.

[0037] Preferably, in this embodiment, two locking screws 13 are arranged at intervals along the height direction of the circular body 11. Adaptively, two through holes 112 are arranged at intervals on the side surface of the circular body 11, and the two locking screws 13 are respectively screwed into the two through holes 112 to further strengthen the locking degree of the installation shaft.

[0038] Further preferably, one end of the through hole 112 is provided with a countersunk hole 113 connected thereto, the head of the locking screw 13 is placed in the countersunk hole 113, the bottom of the countersunk hole 113 forms an angle of 2° with the horizontal plane, and the side of the bottom of the countersunk hole 113 close to the center of the circular body 11 is lower than the side away from the circular body 11. Furthermore, the gap groove 111 divides the through hole 112 into two parts, and the side of the part close to the countersunk hole 113 away from the center of the circular body 11 forms an angle of 2° with the vertical plane, and gradually moves away from the center of the circular body 11 from one end close to the countersunk hole 113 to the end away from the countersunk hole 113.

[0039] Through the above arrangement, during the installation process, the locking screw 13 is passed through the countersunk hole 113 and further screwed into the through hole 112. Since the inclination of the bottom of the countersunk hole 113 and one side of the through hole 112 is 2°, when the locking screw 13 is screwed into the through hole 112, the countersunk hole 113 and the through hole 112 will rotate around the axis of the circular body 11. In this embodiment, when the locking torque of the locking screw 13 reaches 30nm, the countersunk hole 113 and the part where the through hole 112 is located rotate 2°, that is, the bottom of the countersunk hole 113 is horizontal, and the head of the locking screw 13 is completely in contact with the bottom of the countersunk hole 113. At this time, the force arm distance between the locking force of the locking screw 13 and the axis of the circular body 11 is the largest, and the locking torque of the installation shaft reaches the maximum.

[0040] Further, see Figure 4 The locking mechanism 1 also includes a disassembly screw 14. A blind hole 114 is provided on the side surface of the circular body 11. The blind hole 114 passes through the gap groove 111. The disassembly screw 14 is screwed into the blind hole 114. During installation, the installation shaft is inserted into the inner hole of the circular body 11, and the disassembly screw 14 is screwed into the blind hole 114. The bottom of the disassembly screw 14 abuts against the bottom of the blind hole 114.

[0041] For example, the disassembly screw 14 includes an abutment portion and a threaded portion, the threaded portion is threadedly connected to a portion of the blind hole 114 located on one side of the gap groove 111, and one end of the abutment portion away from the threaded portion abuts against the bottom of the blind hole 114. In addition, the disassembly screw 14 provided in this embodiment also includes a limiting portion, which is located between the abutment portion and the threaded portion, and the size of the limiting portion is larger than the size of the open end of the blind hole 114, so as to achieve a limiting effect and prevent the disassembly screw hole from falling off.

[0042] By providing the disassembly screw 14 and the blind hole 114, on the one hand, the screwing degree of the disassembly screw 14 can be adjusted according to actual needs to adjust the inner hole diameter size of the circular body 11 to adapt to installation shafts with different tolerances. In this embodiment, the adjustment range of the inner hole diameter of the circular body 11 is 0-0.05mm.

[0043] On the other hand, after the easily disassembled flexible coupling provided in the present embodiment has been used for a period of time, the disassembly screw 14 is screwed in and tightened so that the bottom of the disassembly screw 14 is against the bottom of the blind hole 114, thereby increasing the inner hole diameter of the circular body 11, so that the sleeve provided in the present embodiment can be easily separated from the mounting shaft, effectively avoiding the situation where the sleeve will not return to its initial state and cannot be effectively separated from the mounting shaft due to the adhesion between the inner hole wall of the circular body 11 and the surface of the mounting shaft after long-term use, even if the locking screw 13 is unscrewed.

[0044] Preferably, in this embodiment, the two locking screws 13 are disposed on both sides of the disassembly screw 14 to improve the uniformity of the locking torque.

[0045] See also Figure 2 The outer wall of the circular body 11 is provided with an annular groove 115, and the middle area of ​​the circular body 11 is horizontally provided with a cut groove 116. Preferably, the cross-sectional shape of the cut groove 116 is semi-circular, and both ends of the annular groove 115 are connected to the cut groove 116, and one end of the clearance groove 111 is connected to the cut groove 116, that is, the cross-sectional shape of the annular groove 115 is also semi-circular, and the other end of the clearance groove 111 extends along the height direction of the circular body 11 to communicate with the cut groove 116. By providing the annular groove 115 and the cut groove 116, on the one hand, the vibration of the installation shaft is absorbed, the pressure of the connecting mechanism 2 is reduced, and the service life is extended; on the other hand, by providing the annular groove 115, the cut groove 116 is cut out at the annular groove 115, the processing technology of the jacket is improved, and the processing allowance is reduced. For example, the consumption of raw materials for a single set of couplings is saved by 5%.

[0046] See also Figure 2 The connection mechanism 2 includes a sheath 21, which is divided into two parts. One part of the sheath 21 is installed on the claws 12 of one of the locking mechanisms 1 in a one-to-one correspondence and extends into the gap between two adjacent claws 12 of the other locking mechanism 1, and the other part of the sheath 21 is installed on the claws 12 of the other locking mechanism 1 in a one-to-one correspondence and extends into the gap between two adjacent claws 12 of one of the locking mechanisms 1. The connection mechanism 2 also includes a fixing screw 23, which passes through the sheath 21 and is screwed to the corresponding claw 12.

[0047] Preferably, the projection of the sleeve 21 on the horizontal plane coincides with the projection of the claw 12 on the horizontal plane. Further preferably, in this embodiment, the projection shape of the sleeve 21 and the claw 12 on the horizontal plane is fan-shaped. In other feasible embodiments, it can also be plum blossom-shaped, which is not specifically limited here.

[0048] Furthermore, the two sides of the claw 12 in one locking mechanism 1 cooperate with the two sides of the corresponding sheath 21 to form two first grooves, and the two sides of the claw 12 in the other locking mechanism 1 cooperate with the two sides of the corresponding sheath 21 to form two second grooves. The connecting mechanism 2 also includes an intermediate body 22, and the intermediate body 22 is embedded in the first groove body and the second groove body relative to each other, so as to compensate for eccentricity, deflection, axial displacement, reduce vibration, and suppress resonance.

[0049] Preferably, the intermediate body 22 includes a sphere 221, the first slot body and the second slot body are both hemispherical structures, the sphere 221 is embedded in the first slot body and the second slot body relative to each other, and the sphere 221 is tangent to the first slot body and the second slot body, thereby increasing the contact area between the intermediate body 22 and the jacket. For example, under the same working conditions, the pressure on the intermediate body 22 and the claws 12 on the jacket of the easily detachable coupling provided in this embodiment is reduced by 15%, thereby increasing the service life of the easily detachable coupling.

[0050] Preferably, the sheath 21 connected to one of the locking mechanisms 1 is spaced apart from the other locking mechanism 1, that is, a portion of the sheath 21 installed on the claws 12 of one of the locking mechanisms 1 in a one-to-one correspondence extends into and is spaced apart from the gap between two adjacent claws 12 of the other locking mechanism 1, and another portion of the sheath 21 installed on the claws 12 of the other locking mechanism 1 in a one-to-one correspondence extends into and is spaced apart from the gap between two adjacent claws 12 of one of the locking mechanisms 1.

[0051] Furthermore, the intermediate body 22 also includes two guide pillars 222 arranged relatively on the sphere 221, and the axis of the guide pillar 222 passes through the center of the sphere 221. The two guide pillars 222 respectively abut against the end surfaces of the two circular bodies 11, and first grooves are respectively arranged on both sides of the claw 12 of one locking mechanism 1, and the two first grooves are correspondingly connected to the two first groove bodies, and the first grooves extend to the end surface of the circular body 11, and second grooves are respectively arranged on both sides of the claw 12 of the other locking mechanism 1, and the two second grooves are correspondingly connected to the two second groove bodies, and the second grooves extend to the end surface of the circular body 11, and the groove walls of the relative first grooves and the groove walls of the second groove cooperate to form a hole, and the guide pillar 222 extends into the hole and circumferentially abuts against the groove walls of the relative first groove and the groove walls of the second groove.

[0052] The above structure realizes the flexible connection of the two locking mechanisms 1, and at the same time enables the easily disassembled flexible coupling provided by this embodiment to withstand a certain range of eccentricity, deflection angle and axial displacement.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
