Horizontal installation tool for cylindrical roller bearing of wind driven generator
Technical Field
The utility model relates to the technical field of wind driven generators, in particular to a horizontal installation tool for a cylindrical roller bearing of a wind driven generator.
Background
Along with the continuous increase of the single machine capacity of the wind generating set, the bearing used by the generator is larger and larger, when the large cylindrical roller bearing is vertically installed, the large cylindrical roller bearing does not need to be guided, but is in a horizontal state on a tower, the use requirements cannot be met by manual carrying and common installation methods, and some tool tools need to be used during installation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art, provides a horizontal type installation tool for a cylindrical roller bearing of a wind driven generator, and can effectively solve the problem that the horizontal type cylindrical roller bearing on a tower of the wind driven generator is difficult to install.
In order to achieve the purpose, the technical scheme provided by the utility model is as follows: a horizontal mounting tool for a cylindrical roller bearing of a wind driven generator is characterized in that a bearing inner ring of the cylindrical roller bearing is heated and then sleeved on a hollow shaft bearing baffle of the wind driven generator; the cylindrical roller bearing comprises a bearing outer ring guide cylinder, a fastening bolt, a jacking support and a screw rod, wherein the bearing outer ring guide cylinder is arranged on the end face of a hollow shaft through the fastening bolt, the axis of the bearing outer ring guide cylinder coincides with the axis of the hollow shaft, the bearing outer ring of the cylindrical roller bearing is sleeved on the bearing outer ring guide cylinder, a plurality of jacking supports are uniformly distributed around the bearing outer ring guide cylinder along the circumference of the bearing outer ring guide cylinder and are fixed on a bearing sleeve of a wind driven generator, the screw rod is connected to the center of each jacking support in a threaded manner, the screw rod extends into a space between the bearing outer ring guide cylinder and the bearing sleeve and is abutted to the bearing outer ring between the bearing sleeve and the bearing outer ring guide cylinder, and the screw rod is screwed so as to push the bearing outer ring to be installed in place.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
the tool has the advantages of reasonable structure, easiness in installation and the like, can be used for directly replacing or installing the large cylindrical roller bearing on the wind turbine tower, greatly improves the installation or replacement efficiency and saves the cost.
