Description

Technical Field

[0001] This application relates to the field of mechanical transmission technology, and in particular, to a new type of coupling. Background Art

[0002] A coupling is a mechanical element used to connect two shafts (or a shaft and a rotating part), which allows a certain displacement between the two shafts and transmits torque at the same time.

[0003] In the prior art, the power transmission systems of industrial equipment mostly use couplings with an integral design. Although such couplings have high strength and reliability, they face many limitations in actual applications. For example, in an environment with limited space, due to the limited space for workers to operate, it is difficult for workers to install, maintain or replace the coupling.

[0004] With the growth of modern industrial production requirements, how to improve the work efficiency of workers in installing, maintaining or replacing couplings and reduce the working hours of workers has become an urgent problem to be solved. Summary of the Utility Model

[0005] In order to facilitate the installation, maintenance or replacement of the coupling by workers and improve the work efficiency of workers, this application provides a new type of coupling.

[0006] A new type of coupling provided by this application adopts the following technical solutions:

[0007] A new type of coupling includes a male component and a female component. The male component is fixedly inserted into the female component. A plugging block is provided on one side of the male component close to the female component, and a plugging groove for the plugging block to be inserted is formed in the female component. A first receiving groove is formed on the side of the male component away from the female component, and a first keyway is formed on the groove side wall of the first receiving groove. A second receiving groove is formed on the side of the female component away from the male component, and a second keyway is formed on the groove side wall of the second receiving groove. The first receiving groove and the second receiving groove are used to receive the rotating shaft, and the first keyway and the second keyway are used to receive the flat key on the outer circumference of the rotating shaft.

[0008] By adopting the above technical solutions, the coupling is divided into a male component and a female component that are fixedly inserted, so as to facilitate workers to install, repair or replace the coupling in a narrow space and improve the work efficiency of workers.

[0009] At the same time, the male component and the female component are fixedly inserted, so that the offset (including axial offset and radial offset) between the rotating shafts on both sides of the coupling caused by installation accuracy, deformation and thermal expansion can be compensated, so as to improve the stability and reliability of the coupling transmission.

[0010] Optionally, the insertion slot is a through slot.

[0011] By adopting the above technical solution, by setting the insertion slot as a through slot, the radial offset of the rotating shafts on both sides of the coupling is compensated, facilitating the installation of the coupling by the staff.

[0012] Optionally, the outer side of the insertion block is flush with the outer side of the female component.

[0013] By adopting the above technical solution, the insertion blocks are fully paved in the insertion slots, thereby improving the connection strength between the male component and the female component, so as to facilitate the male component to transmit torque to the female component.

[0014] Optionally, the first keyway, the second keyway intersect with the vertical projection plane of the insertion block.

[0015] By adopting the above technical solution, the first keyway, the second keyway and the insertion block are located on the same straight line, thus facilitating the transmission of torque between the rotating shaft, the male component, the female component and the rotating shaft, reducing the structural damage of the coupling, and prolonging the service life of the coupling.

[0016] Optionally, a first threaded hole is provided on the groove side wall of the first receiving groove, a second threaded hole is provided on the groove side wall of the second receiving groove, and the first threaded hole and the second threaded hole are for a bolt to pass through, and the bolt is fixedly connected to the rotating shaft.

[0017] By adopting the above technical solution, the position of the rotating shaft in the coupling is further fixed by the bolt, so as to improve the connection strength between the rotating shaft and the coupling, and facilitate the transmission of force between the rotating shaft and the coupling.

[0018] Optionally, there are several first threaded holes, and at least one of the first threaded holes is arranged opposite to the first keyway.

[0019] By adopting the above technical solution, at least one first threaded hole is arranged opposite to the first keyway, so that at least one bolt is arranged opposite to the first keyway and the flat key on the rotating shaft, thereby improving the transmission effect between the rotating shaft and the coupling and reducing the structural damage of the coupling.

[0020] Optionally, along the direction from the middle to both ends of the insertion block, the width of the insertion block increases.

[0021] By adopting the above technical solution, along the direction from the middle to both ends of the insertion block, the width of the insertion block increases, so as to facilitate the transmission of torque between the male component and the female component, reduce the structural damage of the male component and the female component, and improve the service life of the coupling.

[0022] Optionally, along the direction away from the mother part, the insertion slot includes an abutting slot and a guiding slot, and the abutting slot and the guiding slot are communicated with each other; along the direction away from the mother part, the notch area of the guiding slot increases, and the slot side wall of the abutting slot abuts against the insertion block.

[0023] By adopting the above technical solution, by arranging the guiding slot at the notch of the insertion slot, it is convenient for the staff to insert the insertion block into the insertion slot, thereby improving the work efficiency of the staff.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The coupling is divided into a male part and a mother part that are inserted and fixed, so as to facilitate the staff to install, repair or replace the coupling in a narrow space, and improve the work efficiency of the staff;

[0026] 2. The first keyway, the second keyway and the insertion block are located on the same straight line, so as to facilitate the transmission of torque between the rotating shaft, the male part, the mother part and the rotating shaft, reduce the structural damage of the coupling, and extend the service life of the coupling;

[0027] 3. The position of the rotating shaft in the coupling is further fixed by bolts to improve the connection strength between the rotating shaft and the coupling, so as to facilitate the transmission of force between the rotating shaft and the coupling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] The following is combined with the attached Figures 1-5A further detailed description of the present application is provided.

[0035] An embodiment of the present application discloses a novel coupling. Referring to Figure 1 and Figure 2 , the novel coupling includes a male component 1 and a female component 2, and the male component 1 is fixedly inserted into the female component 2.

[0036] Referring to Figure 2 and Figure 3 , a first receiving groove 11 is formed on one side of the male component 1 away from the female component 2, and a first keyway 12 is formed on the groove side wall of the first receiving groove 11; a second receiving groove 21 is formed on one side of the female component 2 away from the male component 1, and a second keyway 22 is formed on the groove side wall of the second receiving groove 21; the first receiving groove 11 and the second receiving groove 21 are used to receive a rotating shaft (including a driving shaft and a driven shaft). A raised flat key is provided on the outer periphery of the end of the rotating shaft, and the first keyway 12 and the second keyway 22 are used to receive the flat key on the outer periphery of the rotating shaft, so that the coupling can rotate together with the rotating shaft. Among them, the male component 1 is fixedly inserted into the driving shaft, and the female component 2 is fixedly inserted into the driven shaft; thus, when the driving shaft rotates, the driving shaft can synchronously drive the driven shaft to rotate through the coupling, thereby realizing the transmission of torque.

[0037] Referring to Figure 2 and Figure 3 , a plug-in block 13 is provided on one side of the male component 1 close to the female component 2, and the female component 2 is provided with a plug-in groove 23 for the plug-in block 13 to be inserted. In this embodiment, the plug-in groove 23 is a through groove; thus, a moving space is given for the plug-in block 13 to move along the length direction of the plug-in groove 23 to compensate for the radial offset of the rotating shafts on both sides of the coupling; thereby improving the transmission stability of the coupling and facilitating the installation of the coupling by the staff. At the same time, the outer side of the plug-in block 13 is flush with the outer side of the female component 2, thereby improving the connection strength between the male component 1 and the female component 2, so as to facilitate the transmission of torque from the male component 1 to the female component 2.

[0038] Referring to Figure 2 and Figure 3 , in this embodiment, the vertical projection planes of the first keyway 12, the second keyway 22 and the plug-in block 13 intersect; so as to facilitate the transmission of torque between the rotating shaft, the male component 1, the female component 2 and the rotating shaft, reduce the structural damage of the coupling, and extend the service life of the coupling.

[0039] Referring to Figure 2 and Figure 3, a first threaded hole 14 is provided in the groove side wall of the first receiving groove 11, and a second threaded hole 24 is provided in the groove side wall of the second receiving groove 21. The first threaded hole 14 and the second threaded hole 24 are used for a bolt to pass through, and the bolt is fixedly connected to the rotating shaft. There are several first threaded holes 14, and at least one first threaded hole 14 is disposed opposite to the first key groove 12. In this embodiment, there are two first threaded holes 14, and one first threaded hole 14 is disposed opposite to the first key groove 12, so that a bolt is disposed opposite to the first key groove 12 and the flat key on the rotating shaft, thereby improving the transmission effect between the rotating shaft and the coupling and reducing the structural damage of the coupling. The fixed connection method between the bolt and the rotating shaft can be bolt connection, abutment, etc. This embodiment does not limit the specific connection method between the bolt and the rotating shaft. The implementation principle of a new type of coupling in the embodiment of the present application is as follows:

[0040] Referring to Figures 1 to 3 , the coupling is divided into a male component 1 and a female component 2 that are plug-connected and fixed, so as to facilitate the staff to install, repair or replace the coupling in a narrow space and improve the work efficiency of the staff.

[0041] At the same time, the male component 1 and the female component 2 are plug-connected and fixed, so that the offset (including axial offset and radial offset) between the rotating shafts on both sides of the coupling due to installation accuracy, deformation, and thermal expansion can be compensated, so as to improve the stability and reliability of the coupling transmission.

[0042] Embodiment 2

[0043] The difference between this Embodiment 2 and Embodiment 1 is that:

[0044] Referring to Figure 4 , along the direction from the middle to both ends of the plug block 13, the width of the plug block 13 increases; thus, when the coupling works, the area of the acting surface between the male component 1 and the female component 2 can be increased, so as to facilitate the transmission of torque between the male component 1 and the female component 2, reduce the structural damage of the male component 1 and the female component 2, and improve the service life of the coupling.

[0045] Embodiment 3

[0046] The difference between this Embodiment 3 and Embodiment 1 is that:

[0047] Referring to Figure 5 , along the direction away from the female component 2, the plug slot 23 includes an abutting slot 231 and a guiding slot 232, and the abutting slot 231 and the guiding slot 232 are communicated; along the direction away from the female component 2, the slot opening area of the guiding slot 232 increases, and the slot side wall of the abutting slot 231 abuts against the plug block 13; that is, by providing the guiding slot 232 at the slot opening of the plug slot 23, it is convenient for the staff to insert the plug block 13 into the plug slot 23, thereby improving the work efficiency of the staff.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
