Description

Technical Field

[0001] The utility model relates to the technical field of elastic couplings, in particular to a quick-release high-elasticity coupling. Background Art

[0002] A coupling is a device that connects two shafts or a shaft and a rotating part. They rotate together during the transmission of motion and power and do not disengage under normal circumstances. It is sometimes also used as a safety device to prevent the connected parts from bearing excessive loads and play an overload protection role.

[0003] The elastic coupling is a type of coupling. It is an integrally molded metal elastomer, usually made by wire cutting of metal round bars. Commonly used materials include aluminum alloy, stainless steel, and engineering plastics. It is suitable for various deviations and precise transmission of torque. The elastic coupling contains an elastic compound with pre-stressed rubber, which can provide additional strength and extend service life. The hub material is high-strength aluminum alloy, which is both lightweight and corrosion-resistant. The rubber component is mainly used for shock absorption, making power transmission smooth and quiet, thereby protecting the driving force and the driven machine.

[0004] However, the existing elastic coupling is installed and fixed with bolts. When a fault occurs, the bolts need to be removed one by one, which takes a long time and affects the maintenance efficiency of the elastic coupling. Therefore, it does not meet the existing needs. We have proposed a quick-release high-elastic coupling. Utility Model Content

[0007] Preferably, the rotary clamping hole is divided into an entrance and an interior, the diameter of the entrance of the rotary clamping hole is consistent with the outer diameter of the connecting cylinder, and the inner diameter of the rotary clamping hole is larger than the length of the anti-dropping clamping piece.

[0008] Preferably, a positioning slot is provided at the entrance of the rotating clamping hole, the length of the positioning slot is consistent with the length of the anti-dropping clamping piece, and the width of the positioning slot is consistent with the width of the anti-dropping clamping piece.

[0009] Preferably, an anti-sway slot is provided on the inner top surface of the rotating clamping hole, and the length and width of the anti-sway slot are consistent with the length and width of the anti-slip clamping piece.

[0010] Preferably, the anti-shake slot and the positioning slot are offset from each other and remain vertical on the projection surface.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model inserts the end of a flat-blade screwdriver into the flat-blade slot and squeezes the rotating piece toward the inside of the connecting half ring, so that the elastic rubber ring is squeezed and compressed. At this time, the anti-slipping card piece is separated from the anti-swaying card slot. Then the staff rotates the rotating piece ninety degrees with a flat-blade screwdriver and loosens the rotating piece. The elastic rubber ring elastically recovers and drives the rotating piece to protrude from the connecting half ring and the anti-slipping card piece to enter the positioning plug-in slot. The operation is repeated for all rotating pieces. Finally, the connecting half ring is taken out from the first card slot and the second card slot.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] like Figures 1 to 5 As shown, a quick-release high-elastic coupling, the two coupling link end blocks 1 are rotationally symmetrical and are clamped with an intermediate elastic connector 2 between them, the outer surface of the intermediate elastic connector 2 is provided with a first clamping groove 11, the outer surfaces of the ends of the two coupling link end blocks 1 connected to each other are provided with a second clamping groove 12, the inner sides of the first clamping groove 11 and the second clamping groove 12 are clamped with two symmetrical connecting half rings 3, the bottom surface of the second clamping groove 12 is provided with a rotating clamping hole 6, the outer surface of the connecting half ring 3 is detachably installed with a rotating piece 4, and an elastic rubber is provided between the rotating piece 4 and the connecting half ring 3 Circle 9, the outer surface of the rotating piece 4 is provided with a straight groove 5, and the inner surface of the connecting half ring 3 is detachably installed with a connecting cylinder 8, which is connected to the rotating piece 4 by screws. One end of the connecting cylinder 8 is fixed with the Yuou anti-slip clamping piece 7, and the anti-slip clamping piece 7 is clamped on the inner side of the rotating clamping hole 6. The connecting half ring 3 is connected and fixed to the coupling link end block 1 through the rotating piece 4, the connecting cylinder 8 and the anti-slip clamping piece 7, ensuring that the two coupling link end blocks 1 will not be easily separated after being connected to each other, and ensuring the structural stability of the two coupling link end blocks 1 after being connected.

[0022] The rotating clamping hole 6 is divided into an entrance and an interior. The diameter of the entrance of the rotating clamping hole 6 is consistent with the outer diameter of the connecting cylinder 8. The inner diameter of the rotating clamping hole 6 is larger than the length of the anti-dropping clamping piece 7. A positioning plug-in groove 13 is provided at the entrance of the rotating clamping hole 6. The length of the positioning plug-in groove 13 is consistent with the length of the anti-dropping clamping piece 7. The width of the positioning plug-in groove 13 is consistent with the width of the anti-dropping clamping piece 7. The inner top surface of the rotating clamping hole 6 is provided with an anti-swaying clamping groove 10. The length and width of the anti-swaying clamping groove 10 are consistent with the length and width of the anti-dropping clamping piece 7.

[0023] The anti-sway card slot 10 and the positioning plug-in slot 13 are offset from each other and remain vertical on the projection surface. The positioning plug-in slot 13 ensures that the anti-sway card connector 7 can smoothly enter the rotating card hole 6, and then the anti-sway card slot 10 is used to clamp and position the anti-sway card connector 7 after rotation, ensuring that the anti-sway card connector 7 will not loosen under external human intervention.

[0024] Working principle: When the high elastic coupling fails or is damaged during use, first remove the high elastic coupling from the end of the transmission shaft, then insert the end of a flat-blade screwdriver into the flat-blade slot 5, and squeeze the rotating piece 4 into the inside of the connecting half ring 3, so that the elastic rubber ring 9 is squeezed and compressed. At this time, the anti-slip card piece 7 is detached from the anti-sway card slot 10, and then the staff rotates the rotating piece 4 ninety degrees with a flat-blade screwdriver so that the anti-slip card piece 7 is flush with the positioning plug-in slot 13, and then slowly loosens the rotating piece 4, and the elastic rubber ring 9 Elastic recovery drives the rotating piece 4, the connecting cylinder 8, and the anti-slipping card piece 7 to move, so that the anti-slipping card piece 7 enters the inner side of the positioning plug-in groove 13, and the rotating piece 4 protrudes from the surface of the connecting half ring 3. The staff only needs to repeat the operation on all the rotating pieces 4 to make the anti-slipping card piece 7 lose connection with the coupling link end block 1, and then remove the two connecting half rings 3 from the anti-swaying card slot 10 and the second card slot 12. The high-elastic coupling can be quickly disassembled, which is convenient for inspection and maintenance of the high-elastic coupling, shortening the operation time and improving maintenance efficiency.
