[0026] The present invention will be described in detail below in conjunction with the embodiments shown in the drawings, but it should be noted that these embodiments are not a limitation of the present invention, and those of ordinary skill in the art make functional, method, or structural improvements based on these embodiments. Equivalent changes or substitutions fall within the protection scope of the present invention.
[0027] Please refer figure 1 , Figure 5 and Figure 7 As shown, in this embodiment, a clamping shell coupling 10 includes: a first clamping shell 1 and a second clamping shell 2 that are split along the axial direction and buckled with each other, the first clamping shell 1 is provided with four first through holes 11, the second clamping shell 2 is provided with four second through holes 21, and the first through holes 11 and the second through holes 21 are continuously passed through.
[0028] Combined reference image 3 versus Image 6 As shown, the clamping shell coupling 10 further includes: a bolt 3 that continuously penetrates the first through hole 11 and the second through hole 21 to buckle the first clamping shell 1 and the second clamping shell 2 to each other 合holding.
[0029] Rejoin Figure 5 As shown, in this embodiment, after the first clamping shell 1 and the second clamping shell 2 are buckled and fixed to each other, two spaced accommodating cavities 211 and 311 can be formed to accommodate the driving shaft 20 and the driven shaft respectively 30. The driving shaft 20 can be driven by a driving device (not shown) to drive the driven shaft 30 through the clamping housing coupling 10, so as to transmit torque.
[0030] Rejoin figure 1 , Figure 5 and Figure 7 As shown, in this embodiment, the inner wall surfaces of the first clamping shell 1 and the second clamping shell 2 are respectively provided with semicircular grooves 12a, 12b that are engaged with each other to form a continuous circular groove 12. , An elastic gasket 121 is embedded in the annular groove 12. Specifically, the elastic gasket 121 includes a rubber gasket, a polytetrafluoroethylene gasket, and preferably a rubber gasket.
[0031] In this embodiment, the annular groove 12 is arranged in the middle of the inner wall surface of the jacket coupling 10 along its longitudinal extension direction. Specifically, the widths of the semicircular grooves 12a, 12b are equal; and the width of the semicircular grooves 12a, 12b is 4 mm. The thickness of the elastic gasket 121 is 4 mm.
[0032] Combine figure 2 versus Figure 4 As shown, in this embodiment, two key grooves 13 are provided on the inner wall surface of the first housing 1. The key groove 13 is symmetrically arranged on both sides of the annular groove 12. The surfaces of the driving shaft 20 and the driven shaft 30 are also provided with key grooves 201 and 301, respectively. The driving shaft 20 and the driven shaft 30 can be clamped with two key grooves 13 provided on the inner wall surface of the first clamping shell 1 through keys (not shown) to realize the clamping shell coupling 10 and the driving shaft 20, The driven shaft 30 is firmly connected.
[0033] Preferably, the width of the continuous circular groove 12 formed by the elastic gasket 121 and the semicircular circular grooves 12a and 12b is equal, and of course it can also be slightly smaller than the width of the continuous circular groove 12. The elastic gasket 121 can effectively reduce the axial vibration generated between the driving shaft 20 and the driven shaft 30, so as to increase the service life of the jacket coupling 10 and increase the service life of the rotomolding equipment.
[0034] The series of detailed descriptions listed above are only specific descriptions of feasible implementations of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementations or implementations made without departing from the technical spirit of the present invention All changes shall be included in the protection scope of the present invention.
[0035] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the foregoing description, and therefore it is intended to fall within the claims. All changes within the meaning and scope of equivalent elements of are included in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
[0036] In addition, it should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for clarity, and those skilled in the art should consider the specification as a whole The technical solutions in the embodiments can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
