Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a thickener coupling. Background Art
[0002] In the papermaking bamboo fiber production line, a high-concentration grinding equipment is required. In this equipment, the knife adjustment connection device uses a spring tube clamp coupling. Sometimes, when the knife adjustment device is automatically running, this coupling will be pulled and cause the coupling to break, making it impossible to adjust the knife normally. In order to reduce the number of coupling damages, a new coupling is needed to replace the conventional spring tube clamp coupling. Utility Model Content
[0003] The utility model aims to provide a thickener coupling which has the effect of being able to transmit torque and withstand short-range axial movement.
[0004] The above technical objectives of the present invention are achieved through the following technical solutions:
[0005] A thickener coupling comprises a first half coupling and a second half coupling, wherein the first half coupling is provided with a socket on the side facing the second half coupling, and the second half coupling can be inserted into the socket on the side facing the first half coupling, the first half coupling is provided with connecting grooves symmetrically along the axial direction on the side, and the connecting grooves are connected to the socket, and the second half coupling is provided with limit shafts symmetrically on the side, and the limit shafts are slidably arranged in the connecting grooves.
[0006] As a further configuration of the present invention, the first half coupling and the second half coupling are coaxially provided with shaft holes, and the shaft holes are respectively connected to the power output shaft and the power input shaft of the thickener.
[0007] As a further configuration of the present invention, the shaft hole includes a connecting plane, and the sides of the power output shaft and the power input shaft of the thickener are provided with matching connecting planes.
[0008] As a further configuration of the present invention, the limiting shaft is threadedly connected to the second half coupling.
[0009] The beneficial effects of the utility model are:
[0010] By arranging a connecting groove on the first half coupling and a limiting shaft on the second half coupling, when the first half coupling rotates, the second half coupling can be driven to rotate through the limiting shaft, thereby transmitting torque. On the other hand, the limiting shaft can slide in the connecting groove, so that the first half coupling and the second half coupling can move a short distance relative to each other in the axial direction, thereby avoiding the situation where the coupling is pulled and damaged during the operation of the knife adjusting device.
