Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling technology, and in particular to a coupling with a buffer function. Background Technology
[0002] A coupling is a device that connects two shafts or a shaft and a rotating component, allowing them to rotate together during motion and power transmission, and remaining connected under normal conditions. Sometimes it is also used as a safety device to prevent the connected components from bearing excessive loads, thus providing overload protection.
[0003] During production, the bag feeding servo coupling of the bagging machine is solid and has no cushioning. If an emergency malfunction occurs during production, resulting in a collision or misposition, it can easily cause damage to the equipment, accessories, and motors.
[0004] In view of this, we propose a coupling with a buffer function. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a coupling with a buffer function to solve the technical problem that the current bag feeding servo coupling of the bag filling machine is solid and has no buffer.
[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a coupling with a buffer function, including half coupling A, half coupling B, connecting ring A and connecting ring B;
[0007] Half-coupling A and half-coupling B are connected to form a coupling;
[0008] Connecting ring A is sleeved on the half coupling A;
[0009] Connecting ring B is sleeved on the half coupling B;
[0010] The connecting ring A and the connecting ring B are fixedly connected by two sets of symmetrically distributed bolts and nuts;
[0011] The outer ring walls of the mating ends of the half-coupling A and the half-coupling B are respectively provided with threaded grooves, and the threaded grooves on the half-coupling A and the half-coupling B are mated to form a threaded buffer groove.
[0012] The threaded groove is connected to the through hole between half-coupling A and half-coupling B.
[0013] Preferably, the mounting holes on the half-coupling A and half-coupling B are offset from the bolts and nuts.
[0014] Preferably, buffer structures are arranged in each of the two threaded grooves;
[0015] The buffer structure includes a threaded bar;
[0016] The threaded strip is embedded in the threaded groove;
[0017] The threaded strip has threaded spring pieces arranged on its upper and lower sides, and the threaded spring pieces are pressed against the inner wall of the threaded groove.
[0018] Preferably, the cross-section of the threaded spring is arc-shaped, and the arched end of the threaded spring contacts the inner wall of the threaded groove.
[0019] Preferably, a gap is left between the upper and lower sides of the threaded strip and the inner wall of the threaded groove.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This utility model, by setting half-coupling A, half-coupling B, connecting ring A, connecting ring B and threaded groove, has the advantage that the threaded grooves set at the opposite ends of half-coupling A and half-coupling B make the opposite ends of half-coupling A and half-coupling B spiral, which can be squeezed and play a buffering role when squeezed, thus solving the problem that the bag feeding servo coupling of the bag filling machine is solid and has no buffer.
[0022] 2. This utility model, by setting threaded strips and threaded spring sheets, has the advantage of assisting the buffering of half-coupling A and half-coupling B. When half-coupling A and half-coupling B are squeezed, the threaded spring sheets are squeezed to provide a buffering force. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0030] Example 1: A coupling with a buffer function, see [link / reference] Figures 1 to 4 It includes half coupling A1, half coupling B2, connecting ring A3 and connecting ring B4;
[0031] Half-couplings A1 and B2 are joined together to form a coupling; connecting ring A3 is fitted onto half-coupling A1; connecting ring B4 is fitted onto half-coupling B2; connecting rings A3 and B4 are fixedly connected by two sets of symmetrically distributed bolts 6 and nuts 7; bolts 6 pass through holes on connecting rings A3 and B4, and nuts 7 are screwed onto the end of bolts 6 that passes through; threaded grooves 8 are respectively opened on the outer ring walls of the joint ends of half-couplings A1 and B2, and the threaded grooves 8 on half-couplings A1 and B2 are joined together to form a threaded buffer groove; the threaded grooves 8 are connected to the through holes in the middle of half-couplings A1 and B2.
[0032] This utility model, by setting half-coupling A1, half-coupling B2, connecting ring A3, connecting ring B4 and threaded groove 8, has the advantage that the threaded groove 8 set at one end of half-coupling A1 and half-coupling B2 makes the opposite end of half-coupling A1 and half-coupling B2 spiral, which can be squeezed and play a buffering role when squeezed, thus solving the problem that the bag feeding servo coupling of the bag filling machine is solid and has no buffer.
[0033] Specifically, the mounting holes on half-couplings A1 and B2 are staggered from those on bolts 6 and nuts 7, which does not affect the docking and installation of half-couplings A1 and B2 with the external shaft.
[0034] Furthermore, buffer structures 5 are arranged in the two threaded grooves 8 respectively;
[0035] The buffer structure 5 includes a threaded bar 501; the threaded bar 501 is helically embedded in the threaded groove 8; wherein, threaded spring pieces 502 are arranged on the upper and lower sides of the threaded bar 501, and the threaded spring pieces 502 are pressed and engaged with the inner wall of the threaded groove 8.
[0036] This utility model, by setting threaded strip 501 and threaded spring 502, has the advantage of assisting the buffering of half coupling A1 and half coupling B2. When half coupling A1 and half coupling B2 are squeezed, the threaded spring 502 is squeezed to provide a buffering force.
[0037] Furthermore, the cross-section of the threaded spring 502 is arc-shaped, and the arched end of the threaded spring 502 contacts the inner wall of the threaded groove 8; the arc-shaped threaded spring 502 is easy to bend and subsequently spring back when squeezed.
[0038] It is worth noting that there is a gap between the upper and lower sides of the threaded bar 501 and the inner wall of the threaded groove 8, which does not affect the buffering of the half-coupling A1 and the half-coupling B2.
[0039] Working principle: Using the device of this utility model, the threaded bar 501 and the threaded spring 502 are helically embedded in the threaded groove 8; the opposite ends of the half-coupling A1 and half-coupling B2 are connected, and the threaded grooves 8 on the half-coupling A1 and half-coupling B2 are connected to form a threaded buffer groove. The bolt 6 passes through the holes on the connecting ring A3 and connecting ring B4, and the nut 7 is screwed onto the end of the bolt 6 through which it passes, thus connecting and installing the half-coupling A1 and half-coupling B2 with the external shaft. When subjected to compression, the helical shape of the opposite ends of the half-coupling A1 and half-coupling B2 can be compressed to provide a buffering effect, and the threaded spring 502 is compressed to provide a buffering force.
[0040] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
