Detailed description of the invention
In order to deepen, to understanding of the present utility model and understanding, below in conjunction with the drawings and specific embodiments, to illustrate the utility model further.
embodiment 1:
See Fig. 1, Fig. 2, a kind of press dismounting gearbox gear auxiliary assembly tool, described auxiliary assembly tool comprises dismounting aid and assembling aid, described dismounting aid comprises push rod 1, annular clamping plate 2 and support tube 3, described assembling aid comprises top cylinder 4 and base 5, described annular clamping plate 2 are arranged on support tube 3, and described top cylinder 4 is arranged on base 5; Described dismounting aid and assembling aid all act on gearbox gear, and described gearbox gear comprises spacer 6, gear 7 and gear shaft 8.
embodiment 2:
See Fig. 1, Fig. 3, improve as one of the present utility model, described annular clamping plate 2 are made up of two semicircle annular slabs, and gear 7 blocks by two semicircular annular slabs, and annular slab contacts with gear shaft four sides.Guarantee gear surrounding uniform force, avoid gear secondary damage, the internal diameter of described annular clamping plate 2 is greater than the diameter of gear shaft 8, and object ensures that minimum gear also can be dismantled; The external diameter of described annular clamping plate 2 is greater than support tube 3 external diameter.All the other structures are identical with embodiment 1 with advantage.
