Problems solved by technology
[0004] First, the assembly load of the energy storage spring 85 is relatively large, 8130N, and the free height is 505mm, which cannot be manually pressed.
[0005] Second, the nut 844 and the ratchet 866 are rotated by bearings in the circumferential direction. During assembly, the keyways on the nut 84 and the ratchet 86 will be in the center position, and when the end face of the keyway of the nut 84 is in contact with the end face of the ratchet 86 during assembly, the front The distance between the lower end surface of the cover and the upper end surface of the front flange 88 is only 18mm, and other positions are closed, so it is not easy to observe whether the keyway is in the middle of the cylinder
[0006] Third, because the spring receives a certain torque when compressed, it will drive the front cover to rotate counterclockwise. During the assembly process, the outer circle of the front cover will overlap the end face of the front flange 88 and cannot enter the front flange 88, or After the front cover is pressed into the front flange 88, the 6 mounting holes cannot be completely aligned
