Detailed Description
Referring to fig. 4-6, fig. 4-6 show a novel coupling flange sleeve, which comprises a front coupling sleeve 1 and a rear coupling sleeve 2, wherein the front coupling sleeve 1 and the rear coupling sleeve 2 are of an integrated structure, a shaft hole is formed in the front coupling sleeve, and a key slot 3 is formed in the side wall of the shaft hole along the axis;
The end of the front connecting sleeve 1 far away from the rear connecting sleeve 2 is a flange end face 11, and a plurality of through holes 12 are formed in the flange end face 11 without threads, so that the difficulty of processing and manufacturing is reduced. The outer side wall of the front connecting sleeve 1 is provided with a plurality of sinking grooves, and one side of the sinking grooves, which is close to the flange end face 11, is provided with a communication hole. The communication hole communicates with the through hole 12. A bolt can penetrate the communication hole and the through hole 12.
The number of through holes 12 on the flange end face 11 is consistent with that of the sinking grooves, and the through holes are evenly distributed along the axis of the front connecting sleeve 1, so that the stress is even.
Due to the arrangement of the countersink, the outer diameter of the front coupling sleeve 1 is designed to be larger than the outer diameter of the rear coupling sleeve 2. Therefore, the root of the sinking groove and the inner wall of the shaft hole still have enough thickness, and the use strength of the connecting flange sleeve can be ensured.
When the universal shaft is used, the bolts are placed in the sinking grooves and then pass through the communication holes to reach the outer side of the flange end face 11, the universal shaft 5 is installed from one side of the front connecting sleeve 1, and after the bolts pass through the flange end face 11 connected with the universal shaft 5, nuts are assembled on the bolts, so that the connection between the universal shaft 5 and the connecting flange sleeve can be realized. Simple structure, easy processing and manufacturing. As shown in particular in fig. 4.
The countersink in this embodiment is a bolt countersink 13, which is of a length to accommodate the insertion of a bolt. The bolt adopts a hexagon head bolt, and when the bolt penetrates, the bolt head faces one side of the rear connecting sleeve.
Furthermore, in order to ensure that the bolts can pass through the front coupling sleeve 1 and the flange end face 11 of the cardan shaft 5, the minimum distance of the bolt countersink 13 from the flange end face 11 is designed to be smaller than the length of the bolt countersink 13 in the axial direction of the front coupling sleeve 1. The concrete size of the bolt sinking groove 13 is determined according to the thickness of the flange end face of the universal shaft 5, and the bolt can pass through the flange sinking groove.
As an embodiment, the bolt sinking groove 13 is a rectangular groove, as shown in fig. 6, and is convenient to process, and the long edge of the bolt sinking groove is axially arranged along the front coupling sleeve 1. After the bolts are inserted into the grooves along Zhou Xiangsai, the bolts vertically pass through the front coupling sleeve 1 and the flange end face 11 of the universal shaft 5.
Preferably, the depth of the rectangular slot is greater than the bolt head dimension.
Because the flange end face 11 of the front connecting sleeve 1 adopts the through hole 12 and is in a thread-free design, in order to prevent the bolt from rotating after being inserted and affecting the nut assembly, a small installation gap is reserved between the edge of the hexagon head bolt and the bottom of the countersink groove after the bolt is inserted into the through hole 12, so that the bolt can be prevented from rotating while the installation is convenient.
In the connecting flange sleeve, the communication hole is positioned at the center of the short side of the rectangular groove, and the four corners of the rectangular groove are provided with chamfers.
In order to facilitate the positioning of the universal shaft 5, a positioning groove 4 is formed in one side of the flange end face 11 of the front connecting sleeve 1, and the diameter of the positioning groove 4 is larger than that of the shaft hole and cannot exceed the bottom of the sinking groove.
