Fig. 1 is a schematic view of an embodiment of a cast coupling provided by the present invention;
fig. 2 is a front view of an embodiment of a connector according to the present invention.
Wherein: 1. a first connecting member; 2. a second connecting member; 3. an output shaft; 4. an input shaft; 5. an electric motor; 6. a disc; 7. a convex round block A; 8. a through hole; 9. a positioning key; 10. a convex circular ring B; 11. positioning holes; 12. connecting holes; 13. a buffer sleeve; 14. and (7) connecting pins.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the coupler comprises a first connecting piece 1 and a second connecting piece 2, wherein the first connecting piece 1 is connected with the second connecting piece 2; the first connecting piece 1 is connected with the output shaft 3, and the second connecting piece 2 is connected with the input shaft 4. The other end of the input shaft 4 is connected to a motor 5.
The first connecting piece 1 and the second connecting piece 2 are fixedly connected through a connecting pin 14.
As shown in fig. 2, the first connecting member 1 and the second connecting member 2 are both in the shape of a disc 6, and a raised circular block a7 is arranged at the center of the disc 6; the center of the convex round block A7 is provided with a through hole 8, the through hole 8 is used for installing the output shaft 3 or the input shaft 4, and the depth of the through hole 8 is increased through the arrangement of the convex round block A7, so that the output shaft 3 or the input shaft 4 installed in the through hole 8 is connected with the through hole 8 in the axial direction more, and the connection tightness of the output shaft and the input shaft is higher; meanwhile, the output shaft 3 or the input shaft 4 is connected with the first connecting piece 1 or the second connecting piece 2 through the positioning key 9, and the positioning key 9 can realize axial positioning and circumferential positioning.
Meanwhile, the center parts of the first connecting piece 1 and the second connecting piece 2 are both provided with the convex round blocks A7, namely the center thickness of the connecting pieces is higher than the thickness of the periphery of the connecting pieces, and the arrangement is beneficial to reducing the whole weight of the connecting pieces besides ensuring that the through holes 8 arranged on the center parts have enough hole depth, thereby increasing the transmission efficiency of the output shaft 3.
The disc 6 of the first and second link members 1 and 2 are provided with a plurality of coupling holes 12 at the circumference thereof, and the coupling holes 12 are used for fitting coupling pins 14.
