Abstract
This utility model relates to a kind of bearing assembled unit that can quickly exchange for, including bearing block, driving shaft, bearing, fixing jump ring and spacing jump ring, bearing holder (housing, cover) is together on driving shaft, driving shaft is fixed with bearing by the upper shaft shoulder of driving shaft and fixing jump ring and is connected, driving shaft and bearing holder (housing, cover), together in bearing block, are provided with spacing jump ring at the lower shaft shoulder of driving shaft.The structure separated alone due to this utility model employing bearing portions, when mandrel needs repairing and changes, only need to pull down bearing unit, it is not necessary to dismounting bearing, can pull down mandrel, easy to operate, simple in construction, rationally；Without bearing is pulled down from axle during the dismounting of this utility model device, reduce the risk of bearing damage, improve the life-span of bearing.
Description
Technical field
This utility model relate to a kind of be applicable to machinery upper shaft rotate quickly exchange assembled unit for.
Background technology
Bearing block is to have to use for a kind of structure in rotating machinery.At present, mandrel actuating device traditional on market is: use a mandrel to fix, one end of axle and bearing fit, one end and actuating device set, when keeping in repair and change when, the running part of whole device and standing part need to be pulled down, just can be replaced and keep in repair.Use said method, be primarily present following shortcoming: 1, dismounting and assembly process are loaded down with trivial details, waste time and energy；Whole device under must dismantling when 2, changing, has changed and has needed to assemble one by one；3, bearing and axle are interference fit, dismounting inconvenience, and are easily damaged bearing.
Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, simple to operate, can complete without dismantling whole device, reassemble the bearing combination that can quickly exchange for simply and easily after keeping in repair and changing when keeping in repair and change.
This utility model is achieved through the following technical solutions:
A kind of bearing assembled unit that can quickly exchange for, including bearing block, driving shaft, bearing, fixing jump ring and spacing jump ring, described bearing holder (housing, cover) is together on driving shaft, described driving shaft is fixed with bearing by the upper shaft shoulder of driving shaft and fixing jump ring and is connected, described driving shaft and bearing holder (housing, cover), together in bearing block, are provided with spacing jump ring at the lower shaft shoulder of described driving shaft.
Further, described bearing block side is provided with bearing cap, and described bearing cap is provided with centre bore, and described driving shaft is connected through centre bore with bearing.
Further, described driving shaft side offers through hole.
Further, it is provided with sealing ring between described bearing cap and driving shaft.
The beneficial effects of the utility model are: compared with prior art have the advantage that:
1, the structure separated alone due to this utility model employing bearing portions, when mandrel needs repairing and changes, only need to pull down bearing unit, it is not necessary to dismounting bearing, can pull down mandrel, easy to operate, simple in construction, rationally；
2, without bearing is pulled down from axle during the dismounting of this utility model device, reduce the risk of bearing damage, improve the life-span of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is left view of the present utility model.
Wherein: 1, bearing block, 2, bearing cap, 3, driving shaft, 101, bearing, 102, fixing jump ring, 103, spacing jump ring, 104, sealing ring, 105, through hole.
Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings this utility model is described further.
As it is shown in figure 1, a kind of bearing assembled unit that can quickly exchange for, including bearing block
1, driving shaft 3, bearing 101, fixing jump ring 102 and spacing jump ring 103, bearing 101 is sleeved on driving shaft 3, driving shaft 3 is fixed with bearing 101 by the upper shaft shoulder of driving shaft 3 and fixing jump ring 102 and is connected, driving shaft 3 and bearing 101 are sleeved in bearing block 1, are provided with spacing jump ring 103 at the lower shaft shoulder of driving shaft 3.
In the present embodiment, bearing block 1 side is provided with bearing cap 2, and bearing cap 2 is provided with centre bore, and driving shaft 3 is connected through centre bore with bearing 101.
In the present embodiment, driving shaft 3 side offers through hole 105.
In the present embodiment, sealing ring 104 it is provided with between bearing cap 1 and driving shaft 3.
When rotating shaft device on machinery needs repairing and changes, shut down, treat that mandrel stops operating, the screw that the bearing block unit that comes loose is connected with machine body part, takes off and quickly exchanges bearing assembled unit for, can take off arbor portions and keep in repair and change；After maintenance and replacing complete, arbor portions connects and mission part, then is connected quickly exchanging bearing assembled unit for mandrel, will quickly exchange bearing assembled unit and machine body part fastened by screw for.The structure separated alone due to this utility model employing bearing portions, when mandrel needs repairing and changes, only need to pull down bearing unit, it is not necessary to dismounting bearing, can pull down mandrel, easy to operate, simple in construction, rationally；Without bearing is pulled down from axle during the dismounting of this utility model device, reduce the risk of bearing damage, improve the life-span of bearing.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
