[0016] 5. Economic benefits: The oil seal of the integrated transmission device leaks oil and requires 6 hours of retesting on the test bench. Using this disassembly device saves 5.5 hours, further improving economic efficiency. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1As shown, a disassembly device for an input shaft assembly of a comprehensive transmission device includes a connecting body 1 and a spring pressure plate 2. The input shaft assembly includes an input shaft 3, a nut 4, a retaining ring 5, and a stop washer 6. The input shaft 3 is threaded to the end of the nut 4. The outer circumference of the nut 4 has multiple through grooves, and the inner side of the outer end of the nut 4 has a first annular groove. The stop washer 6 is provided in the first annular groove. A retaining ring 5 is installed at the position of each through groove on the nut 4 to limit the stop washer 6. The connecting body 1 is provided on the outer side of the shaft end of the input shaft 3. A spring pressure plate 2 is provided on the outer side of the nut 4 corresponding to the position of each through groove. All the spring pressure plates 2 are installed on the connecting body 1. The inner side of the lower end of each spring pressure plate 2 is provided with a protrusion for pressing down the retaining ring 5.

[0020] The connecting body 1 has a through first threaded hole in the middle, and the first bolt 7 is installed in the first threaded hole, with the front end of the first bolt 7 facing the shaft end of the input shaft 3. When the first bolt 7 is tightened so that the front end of the first bolt 7 presses against the shaft end of the input shaft 3, the reverse force generated by the tightening force of the first bolt 7 enables the first bolt 7 to function as a jack.

[0021] The upper part of the connecting body 1 has the same number of slots 8 as the spring pressure plates 2. Each spring pressure plate 2 has a locking block 9 on the inner side of its upper end that cooperates with the slot 8. The upper outer side of the spring pressure plate 2 has a receiving groove. After all the locking blocks 9 of the spring pressure plates 2 are inserted into the slots 8, an O-ring 10 is placed in the receiving groove on the outer side of the upper end of the spring pressure plate 2 to lock the locking blocks 9 and the slots 8. Through the cooperation of the locking blocks 9, the slots 8, and the O-ring 10, the upper end of the spring pressure plate 2 is fastened to the upper part of the connecting body 1.

[0022] The lower part of the connecting body 1 has the same number of second threaded holes as the spring pressure plates 2. Each spring pressure plate 2 has a through hole in the middle. A second bolt 11 is provided on the outer side of the middle of each spring pressure plate 2. The second bolt 11 passes through the small washer 13 and the through hole of the spring pressure plate 2 and is screwed into the corresponding second threaded hole, thereby pressing the spring pressure plate 2 and the connecting body 1 together.

[0023] A spring 12 is fitted on the second bolt 11. The two ends of the spring 12 are connected to the spring pressure plate 2 and the connecting body 1, respectively. The elastic force of the spring 12 can be used to pop out the spring pressure plate 2.

[0024] The working process of this utility model is as follows: First, all the spring pressure plates 2 are arranged in a ring, so that the protrusion on the inner side of the lower end of each spring pressure plate 2 is aligned with a retaining ring 5, and the locking block 9 on the inner side of the upper end of each spring pressure plate 2 is aligned with a locking groove 8; then, the second bolt 11 is tightened by hand. The second bolt 11 passes through the through hole of the spring pressure plate 2 and is screwed into the corresponding second threaded hole, thereby applying force to the spring pressure plate 2 and compressing the spring. During this process, the locking block 9 on the inner side of the upper end of the spring pressure plate 2 is engaged in the corresponding locking groove 8, and the protrusion on the inner side of the lower end of the spring pressure plate 2 presses the retaining ring 5 inward, causing the retaining ring 5 to disengage from the mounting groove of the inner hole of the nut 4, thereby disengaging the anti-locking washer. After the second bolt 11 is tightened, the O-ring 10 is placed in the receiving groove on the outer side of the upper end of the spring pressure plate 2 to lock the locking block 9 and the locking groove 8, so that the upper end of the spring pressure plate 2 is fastened to the upper part of the connecting body 1. Then, the first bolt 7 is tightened so that the front end of the first bolt 7 abuts against the shaft end of the input shaft 3. The reverse force generated by the tightening force of the first bolt 7 makes the first bolt 7 act as a jack, removing the stop washer 6 and the retaining ring 5, separating them from the nut 4, and achieving smooth disassembly. After removing the stop washer 6 and the retaining ring 5, the O-ring 10 is removed, and the second bolt 11 is loosened. Under the action of the spring force of the spring 12, the spring pressure plate 2 separates from the connecting body 1.
