Description

Technical Field

[0001] The present invention relates to the technical field of couplings, and in particular to a locking disc coupling. Background Art

[0002] In the field of mechanical transmission, the locking disc coupling is a key component that connects two shafts to transmit motion and power. Its installation convenience, alignment accuracy and connection stability directly affect the operating efficiency and service life of the equipment. Existing locking disc couplings usually adopt a single-end step-by-step screw tightening installation method. The operator needs to tighten the screws at both ends one by one. Not only are the operation steps cumbersome and time-consuming, but also during the step-by-step tightening process, it is easy to cause deviations in the alignment accuracy of the two shafts due to uneven force, which in turn causes vibration and noise during equipment operation, and even causes wear of the coupling and shaft. In addition, the structural design of traditional locking disc couplings is mostly suitable for docking shafts with the same diameter. When faced with working conditions where the two shafts have different diameters, additional adapter components are often required, which increases equipment cost and assembly complexity, making it difficult to meet diverse transmission connection needs.

[0003] In view of the above problems, the present invention document proposes a locking disc coupling. Summary of the Invention

In addition, the structural design of the traditional locking disc coupling is mostly suitable for docking shafts with the same diameter. When facing working conditions with different diameters of the two shafts, additional adapter components are often required, which increases equipment cost and assembly complexity, and is difficult to meet the diverse transmission connection requirements. A locking disc coupling is proposed.

[0006] Preferably, one side of the inner ring of the outer annular disc structure is provided as an inclined surface, and both sides of the propulsion pressure plate structure are provided as inclined surfaces.

[0007] Preferably, the adaptive locking assembly includes two liquid storage shells, which are fixedly connected to the propulsion pressure plate structure. A connecting plate is fixedly connected between the two liquid storage shells, and a connecting pipe is passed through the connecting plate. Both ends of the connecting pipe are respectively connected to the two liquid storage shells.

[0008] Preferably, a piston structure is provided inside the liquid storage shell, a first return spring is fixedly connected between the piston structure and the inner wall of the liquid storage shell, a movable part is fixedly connected to one side of the piston structure, and the movable part passes through the liquid storage shell and is fixedly connected to the coupling retaining part.

[0009] Preferably, the outer disc tightening assembly includes a transmission screw, which is rotatably mounted on the annular shell structure via two bearings. A transmission gear is fixedly connected to the transmission screw, and the transmission gear is meshed with a transmission ring gear.

[0010] Preferably, both ends of the transmission screw are threadedly connected to a transmission threaded barrel, and the transmission threaded barrel is installed on the outer annular disc structure.

[0011] Preferably, the elastic connection assembly includes a telescopic rod, a third return spring is provided on the outer sleeve of the telescopic rod, and the third return spring and both ends of the telescopic rod are fixedly connected to the annular shell structure and the propulsion pressure plate structure respectively.

[0012] Preferably, an operating opening is provided on the transmission gear ring, and one end of the portable disassembly and assembly tool is adapted to the size of the operating opening.

[0013] Preferably, the self-locking positioning assembly includes a weight block, which is arranged in the operating port, and both sides of the weight block are fixedly connected to an adjustment plate, and one end of the adjustment plate is fixedly connected to a fixed locking tooth structure.

[0014] Preferably, a second return spring is fixedly connected to one side of the adjustment plate, the second return spring is fixedly connected to the inner wall of the adjustment port, the adjustment plate is slidably connected to the adjustment port, and the adjustment port is opened on the transmission gear ring.

[0015] Compared with the prior art, the present invention provides a locking disc coupling with the following beneficial effects: 1. The locking disc coupling is inserted into the operating port through a convenient disassembly and assembly tool to operate the transmission ring gear and the outer disc tightening assembly, so that the outer disc tightening assembly drives the outer annular disc structures on both sides to move relative to each other. The outer annular disc structure squeezes the push plate structure to move, so that the push plate structure drives the adaptive locking assembly to merge, and the adaptive locking assembly connects the two drive coupling structures together. This method uses a convenient disassembly and assembly tool to synchronously complete the tightening operation of the outer disc tightening assembly, without the need to tighten them step by step, greatly reducing the installation steps and operation time. It is especially suitable for batch assembly or space-constrained operation scenarios, effectively improving assembly efficiency and reducing installation difficulty.

[0016] 2. The locking disc coupling applies pressure to the thrust plate structure through the outer annular disc structure, and the adaptive locking assembly is close to the drive coupling structure. According to the drive coupling structures with different diameters, the coupling clamping piece close to the larger diameter can pre-contact the drive coupling structure, and by continuously applying pressure, the coupling clamping piece drives the piston structure to move through the movable piece, so that the piston structure presses the liquid into another liquid storage shell through the connecting pipe, and the piston structure at another position moves, so that the two coupling clamping pieces are smoothly locked on the two drive coupling structures. This method can be directly applied to the docking of two drive coupling structures with different diameters without the need for additional adapter components, simplifies the structural layout of the transmission system, and improves applicability. Secondly, during the movement of the locking disc coupling mechanism, the load-bearing block is subjected to centrifugal motion, which can exert force on the adjustment plate, so that the fixed lock tooth structure and the positioning tooth structure are always locked, thereby ensuring the firmness of the overall connection.

[0017] 3. The locking disc coupling can rotate the transmission ring gear through the convenient disassembly and assembly tool and the operating port, so that the transmission ring gear and the outer disc tightening assembly are transmitted, and the outer disc tightening assembly drives the two outer annular disc structures to move relative to each other, so that the outer annular disc structure squeezes the push plate structure, and the push plate structure drives the adaptive locking assembly to merge. Through the synchronous merging of multiple adaptive locking assemblies, the two drive coupling structures always maintain a good centering state during the connection process, which significantly improves the centering accuracy and avoids the local stress concentration problem caused by the sequential tightening sequence in the traditional step-by-step operation. This method can maintain a uniform force distribution on the drive coupling structure, which not only reduces the additional stress of the coupling and the drive coupling structure, reduces the risk of vibration and wear caused by centering deviation, but also enables the bearing capacity of the connection part to be fully utilized, ensuring the stability and reliability of the transmission process.

An annular shell structure 107 is provided between the two outer annular disk structures 102. A transmission ring gear 105 is rotatably installed in the annular shell structure 107 through two bearings. The transmission ring gear 105 can rotate stably through the bearings, so that the transmission ring gear 105 and the transmission gear 1031 are stably transmitted.

The outer sleeve of the telescopic rod 1091 is provided with a third return spring 1092. The push plate structure 104 can be connected to the annular shell structure 107 through the telescopic rod 1091 and the third return spring 1092. At the same time, the third return spring 1092 and the telescopic rod 1091 can be retracted, so that the push plate structure 104 can move smoothly, and the elastic force of the third return spring 1092 can drive the push plate structure 104 Reset, so that the adaptive locking assembly 106 removes the fixation of the drive coupling structure 101, and the third reset spring 1092 and the two ends of the telescopic rod 1091 are fixedly connected to the annular shell structure 107 and the propulsion pressure plate structure 104 respectively. One end of the elastic connection assembly 109 is connected to the propulsion pressure plate structure 104, and the propulsion pressure plate structure 104 is connected to the adaptive locking assembly 106. The outer annular disk structure 102 is squeezed with the propulsion pressure plate structure 104, so that the adaptive locking assembly 106 connects the two drive coupling structures 101 together.

[0024] Example 2: Reference Figure 6 、 Figure 8 and Figure 10A locking disc coupling includes an adaptive locking assembly 106, which includes two liquid storage shells 1063. The two liquid storage shells 1063 are fixedly connected to the push plate structure 104. A connecting plate 1061 is fixedly connected between the two liquid storage shells 1063. A connecting pipe 1062 is passed through the connecting plate 1061. The two liquid storage shells 1063 can be connected through the connecting pipe 1062, so that the liquid can flow between the liquid storage shells 1063. The two ends of the connecting pipe 1062 are respectively connected to the two liquid storage shells. 1063 is connected. A piston structure 1065 is provided inside the liquid storage shell 1063. A first return spring 1064 is fixedly connected between the piston structure 1065 and the inner wall of the liquid storage shell 1063. The first return spring 1064 can drive the piston structure 1065 to reset, so that the piston structure 1065 can drive the movable part 1066 and the coupling retaining part 1067 to reset smoothly. A movable part 1066 is fixedly connected to one side of the piston structure 1065. The movable part 1066 passes through the liquid storage shell 1063 and is fixedly connected to the coupling retaining part 1067. The self-locking positioning assembly 108 includes a weight block 1081, which is arranged in the operating port 112. The weight block 1081 is driven by the locking disc coupling mechanism 100 to apply force to the adjustment plate 1083 through centrifugal motion to maintain a stable connection between the fixed locking tooth structure 1084 and the positioning tooth structure 110, and prevent the fixed locking tooth structure 1084 from being separated from the positioning tooth structure 110, thereby ensuring the stability of the outer disc tightening assembly 103 and preventing the outer disc tightening assembly 103 from loosening and affecting the connection with the drive coupling structure 101. The two sides of the weight block 1081 are fixedly connected with the adjustment plate 1083, and one end of the adjustment plate 1083 is fixed. It is connected to a fixed locking tooth structure 1084, and a second reset spring 1082 is fixedly connected to one side of the adjustment plate 1083. The resetting of the second reset spring 1082 can drive the adjustment plate 1083 to reset, and the resetting of the adjustment plate 1083 can drive the fixed locking tooth structure 1084 to lock with the positioning tooth structure 110, so as to lock the outer disk tightening assembly 103.

According to the different diameters of the drive coupling structures 101, the coupling stopper 1067 close to the larger diameter can pre-contact the drive coupling structure 101, and by continuously applying pressure, the coupling stopper 1067 drives the piston structure 1065 to move through the movable member 1066, so that the piston structure 1065 presses the liquid into the other liquid storage shell 1063 through the connecting pipe 1062, so that the piston structure 1065 at the other position is pressed. The structure 1065 moves, so that the two coupling retaining members 1067 are smoothly locked on the two driving coupling structures 101. This method can be directly applied to the docking of two driving coupling structures 101 with different diameters, without the need for additional adapter components, thereby simplifying the structural layout of the transmission system and improving applicability. Secondly, during the movement of the locking disk coupling mechanism 100, the load block 1081 is subjected to centrifugal motion, which can apply force to the adjustment plate 1083, so that the fixed locking tooth structure 1084 is always locked with the positioning tooth structure 110, thereby ensuring the firmness of the overall connection.

[0026] Example 3: Reference Figure 2-Figure 5 A locking disk coupling includes a locking disk coupling mechanism 100 and a convenient disassembly and assembly tool 200. The locking disk coupling mechanism 100 includes two outer annular disk structures 102. An annular shell structure 107 is provided between the two outer annular disk structures 102. A transmission ring gear 105 is rotatably mounted in the annular shell structure 107 via two bearings. The transmission ring gear 105 is transmission-connected to a plurality of outer disk tightening assemblies 103. The ends of the plurality of outer disk tightening assemblies 103 are respectively connected to the two outer annular disk structures 102. Two sets of positioning tooth structures 110 are fixedly connected to both sides of the inner wall of the annular shell structure 107. The two sets of positioning tooth structures 110 are locked with the self-locking positioning assembly 108. The self-locking positioning assembly 108 is set in the transmission ring gear 105. The inner ring of the annular shell structure 107 is connected to a plurality of elastic connection components 109, one end of the elastic connection component 109 is connected to the propulsion pressure plate structure 104, the propulsion pressure plate structure 104 is connected to the adaptive locking component 106, and the outer annular disk structure 102 is squeezed with the propulsion pressure plate structure 104, so that the adaptive locking component 106 connects the two drive coupling structures 101 together.

[0027] In this embodiment: the transmission ring gear 105 can be rotated by cooperating with the operating port 112 through the convenient disassembly and assembly tool 200, so that the transmission ring gear 105 and the outer disc tightening component 103 are transmitted, and the outer disc tightening component 103 drives the two outer annular disc structures 102 to move relative to each other, so that the outer annular disc structure 102 squeezes the push pressure plate structure 104, so that the push pressure plate structure 104 drives the adaptive locking component 106 to merge. Through the synchronous merging of multiple adaptive locking components 106, the two drive coupling structures 101 always maintain a good centering state during the connection process, which significantly improves the centering accuracy and avoids the problem of local stress concentration caused by the sequential tightening sequence in the traditional step-by-step operation. This method can maintain a uniform force distribution on the drive coupling structure 101, which not only reduces the additional stress on the coupling and the drive coupling structure 101, reduces the risk of vibration and wear caused by centering deviation, but also enables the bearing capacity of the connection part to be fully utilized, ensuring the stability and reliability of the transmission process.

[0028] Working principle: When the two drive coupling structures 101 need to be connected together, the portable disassembly and assembly tool 200 is inserted into the operation port 112, so that the portable disassembly and assembly tool 200 pushes the load block 1081, and the load block 1081 drives the adjustment plate 1083 to move, and the adjustment plate 1083 drives the second return spring 1082 to deform, and the adjustment plate 1083 drives the fixed lock tooth structure 1084 to separate from the positioning tooth structure 110; Then, the convenient disassembly and assembly tool 200 drives the transmission ring gear 105 to rotate through the operation port 112. The transmission ring gear 105 and the transmission gear 1031 transmit power. The transmission gear 1031 drives the transmission screw 1032 to rotate. The transmission screw 1032 drives the two transmission threaded cylinders 1033 to move relative to each other, so that the transmission threaded cylinders 1033 drive the two outer annular disk structures 102 to move relative to each other. The inclined surface of the outer annular disk structure 102 presses the push plate structure 104, and the push plate structure 104 drives the third return spring 109 2. The propulsion plate structure 104 drives the liquid storage shell 1063 to move, causing the coupling retaining member 1067 to contact the drive coupling structure 101. According to the diameter of the drive coupling structure 101, the coupling retaining member 1067 is subjected to force, which can drive the movable member 1066 and the piston structure 1065 to move, causing the piston structure 1065 to transfer the liquid through the connecting pipe 1062 to the other liquid storage shell 1063, thereby causing the two coupling retaining members 1067 to synchronously lock the drive coupling structure 101 in place. After the connection is completed, the portable disassembly tool 200 is taken out, and the second reset spring 1082 drives the weight block 1081 to reset, and the weight block 1081 drives the adjustment plate 1083 and the fixed lock tooth structure 1084 to reset, so that the fixed lock tooth structure 1084 is locked with the positioning tooth structure 110; When disassembly is required, the convenient disassembly and assembly tool 200 is also inserted into the operating port 112 to separate the fixed lock tooth structure 1084 from the positioning tooth structure 110, and then the transmission ring gear 105 is rotated in the opposite direction to make the transmission ring gear 105 and the outer disk tightening assembly 103 drive in the opposite direction, so that the outer annular disk structure 102 moves away from the propulsion pressure plate structure 104, and the third reset spring 1092 drives the propulsion pressure plate structure 104 to reset, so that the propulsion pressure plate structure 104 drives the adaptive locking assembly 106 to expand outward, and the connection of the drive coupling structure 101 can be removed at this time.
