Description

Technical Field

[0001] The utility model belongs to the technical field of installation of a set reducer, in particular to installation equipment for a large set reducer. Background Art

[0002] Among the reducers used for crane lifting, European cranes are very popular. The biggest feature of this type of crane is that the reducer of the lifting mechanism is installed in a set manner, which does not occupy the center distance of the reducer. The base number of the reducer can be reduced, and the cost can be reduced. The competitive advantage is obvious. The lifting reducer adopts a set and the installation method is tight fit.

[0003] The reducer set is installed with a tight fit on the reel shaft. If it is installed by force, it is easy to damage the oil seal and other structures of the reducer, causing damage to the reducer, making the crane unstable or even unable to work. Therefore, an installation device for a large reducer set is proposed. Utility Model Content

[0007] Preferably, the set reducer is set on the periphery of the set reel shaft and is slidably connected to the outer wall of the set reel shaft. The installation method of the set reducer and the set reel shaft is a tight fit, which has the advantage of not occupying the center distance of the reducer.

[0008] Preferably, the concentric screw rod passes through the middle of the through hole, the gasket is glued to the side wall of the pressure plate, the gasket is overlapped with the set reducer, and the gasket is clamped between the pressure plate and the set reducer. The gasket is made of rubber material, which can increase the friction between the pressure plate and the reducer, and can also play a protective role between the set reducer and the pressure plate to prevent the pressure plate from causing damage to the set reducer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the installation equipment of the large-scale set reducer, by arranging concentric screws, pressure plates, spacer collars, top plates and handles, the equipment can make the pressure plate push the set reducer to move on the set reel shaft by rotating the top plate, and gradually put it on the set reel shaft, which is very labor-saving, has high installation efficiency and good matching, will not damage the oil seal and other structures of the set reducer, and has a longer service life; the setting of the connecting bearing and the gasket ensures that the pressure plate will not rotate synchronously with the top plate when the top plate rotates, and the matching gasket can effectively prevent the pressure plate from causing damage to the set reducer.
