To be directly to another element or be indirectly connected on another element.
It is to be appreciated that term " length ", " width ", " on ", " under ", "front", "rear", "left", "right", " vertical ",
The orientation or position relationship of the instruction such as " level ", " top ", " bottom " " interior ", " outer " are to be closed based on orientation shown in the drawings or position
System, is for only for ease of and describes the utility model and simplified description, rather than the device or element of instruction or hint meaning are necessary
With specific orientation, with specific azimuth configuration and operation, therefore it is not intended that limitation to the utility model.
In addition, term " first ", " second " are only used for description purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or
Implicitly include one or more this feature.In the description of the utility model, " multiple ", " several " are meant that two
A or two or more, unless otherwise specifically defined.
Also referring to Fig. 1 and Fig. 2, now large size bearing provision for disengagement provided by the utility model is illustrated.It is large-scale
Bearing disassembling device, including crossbeam 1, pull rod 2 is provided with crossbeam 1, and pull rod 2, for fixing bearing O, also wraps to be symmetrical arranged
Jack 3 is included, to be symmetrical arranged, one end is against on crossbeam 1 jack 3, another to be singly against on the component of bearing O, is used for
Bearing O is ejected from component.
Large size bearing provision for disengagement provided by the utility model, the course of work are：Bearing O is fixed by pull rod 2, is placed
