Detailed Description
The invention will be further described with reference to the following examples:
in order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2 a-2 c and fig. 3 a-3 b, the device of the present invention is composed of a base flange 1, a force transfer plate 2 and a force transfer column 3. One end of the base flange 1 is provided with an end face spline which can be matched with the existing transmission shaft 4; the other end is processed with recess and rectangular shape hole, and the recess is used for cooperating with biography power board 2 or biography power post 3, and the bolt is connected base body flange 1 and transaxle flange 5 through rectangular shape hole, and open at the base body flange center has the lightening hole simultaneously. One end of the force transmission plate 2 is matched with the base flange 1, and the other end of the force transmission plate is matched with the cylindrical surface of the drive axle flange 5 to transmit torque, so that the high-speed low-torque working condition is suitable. One end of the force transmission column 3 is a step matched with the base flange 1, and the other end of the force transmission column is a cylindrical surface matched with the cylindrical surface of the drive axle flange 5, so that large torque can be transmitted, and the force transmission column is suitable for low-speed high-torque working conditions. For the efficiency test with high rotating speed and small torque, the driving bridge can be connected to the test bed by using the base flange 1 and the force transmission plate 2; for the test that the rotating speed is very small but the torque is very big in the static torsion test, the base body flange 1 can be used for being matched with the force transmission column 3 to connect the driving axle to the test bed, and only one set of clamp is needed to meet the requirements when different tests of the driving axle are carried out.
Examples
The schematic representation of the connection of the propeller shaft to the inlet drive axle flange using the device of the present invention is shown in fig. 4 a-4 b below, with the drive axle components other than flange 5 hidden for clarity of illustration. When in connection, the female spline on the end surface of one side of the base flange 1 is matched with the male spline on the end surface of the transmission shaft 4 and is fixedly connected together through bolts; the other side groove of the base body flange 1 is matched with the boss of the force transmission plate 2 or the force transmission column 3, and meanwhile, the force transmission plate 2 or the force transmission column 3 is tightly pressed between the base body flange 1 and the drive axle flange 5 through bolt connection, because the cylindrical surfaces of the force transmission plate 2 or the force transmission column 3 and the drive axle flange 5 are designed to be in interference fit. Therefore, the force transmission plate 2 or the force transmission column 3 and the base flange 1 are no longer fixed together by bolts. The transmission shaft 4 and the drive axle flange 5 can be connected together through the steps.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
