Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
Structure of the present utility model expressed is as shown in Figure 1, Figure 2 a kind of device of safe, steady dismounting rolling mill four bearing, for being disassembled from rolling-mill housing 1 by rolling mill bearing 7.
This device can not only be guaranteed to save time, dismantle rolling mill bearing effortlessly, can also guarantee that the bearing under dismantling stands intact, possess and check that cleaning reuses condition.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention in the service life extending rolling mill bearing, the technical scheme that the utility model is taked is:
As shown in Figure 1 and Figure 2, the provision for disengagement of rolling mill bearing of the present utility model, arrange and connect as a whole bracing frame 3 and pivot flange 2, described pivot flange 2 is the steel plate of annular, is fixed on the aperture of the dead eye of described rolling-mill housing 1 by connecting bolt 6; The end face of described rolling mill bearing 7 arranges top board 4; Hold out against between described top board 4 and bracing frame 3 with jack 5.
Specifically, the utility model is by welding production special tooling, and bolted is fixed on the bearing housing of rolling-mill housing 1, with screw jack 5 for power, got off by bearing removal to be replaced in milling train casing safely and smoothly, cleaning checks that errorless bearing can come into operation again.Operating personnel's safety can not only be guaranteed, ensure that cabinet design assembly precision requires not to be destroyed, rolling mill bearing service life can also be reused and extend simultaneously, reduce rolling mill bearing consumption costs.
Described bracing frame 3 comprises a "T"-shaped bar and three isometric support bars, and three support bars are perpendicular to pivot flange 2 and be fastenedly connected with it, circumferentially uniform at pivot flange 2 of its link position; The other end of three described support bars is connected respectively with three ends of described "T"-shaped bar.
Described "T"-shaped bar and support bar all adopt channel-section steel to make.
The specification of described channel-section steel is 100mm.
The junction of described "T"-shaped bar and the junction of support bar, support bar and pivot flange 2 is provided with strengthens gusset 8.
The specification of described jack 5 is 25 tons.
The method of operating of the provision for disengagement of rolling mill bearing of the present utility model:
Utilize the waste and old quiet labyrinth of milling train, channel-section steel, steel plate etc., welding production thrust support device, prepares one, 25 tons of jack.In unloading process, first to dismantle the sound labyrinth end covers at bearing housing two ends, putting supporting steel plate (i.e. top board 4) into bearing housing endoporus is afterwards pressed on the outer ring of rolling mill bearing 7, then the bracing or strutting arrangement of making is installed on mill housing according to the mounting means bolt of labyrinth ring, finally jack 5 is withstood between supporting steel plate (top board 4) and bracing frame 3, along with jack 5 constantly ejects, according to active force and reaction force principle, rolling mill bearing 7 can move round about, until eject bearing housing completely, realize steadily, the final purpose of dismounting bearing.
This cover thrust device substitutes originally by the mode of sledgehammer impact dismounting bearing, first eliminated the potential safety hazard of sledgehammer shots existence and alleviated operating personnel's labour intensity, steadily can also pull down the bearing not having to damage in addition, cleaning check errorless after can again to reach the standard grade use, simultaneously according to bearing instructions for use, the requirement that rolling bearing load zones extends bearing life cycle can be realized, reduce bearing cost consumption.Can reach save time, object that laborsaving, province's expense ensures safety.
