The utility model discloses a but floating structure fast fastening or unclamp the bearing and accomplish assembly or disassembling operation, its process is few, efficient, simultaneously and since rise tight utricule arrange week of bearing upwards, it is unanimous to make the bearing be out of shape on the circumference, circularity keeps, the assembly quality height.
Description
Technical field
This utility model belongs to technical field of bearings, is specifically related to a kind of quick change bearing block.
Background technology
Existing bearing block generally adopts interference fit to realize the fixing of bearing and bore, it is generally adopted mechanical compaction or hot jacket assembles, take the former, its circularity distortion is caused owing to mechanical force lower ball cover exists deformation, make dead eye circularity distortion and bearing outer ring poor fit, affect rotating mass and service life；Taking the latter, its operation is cumbersome, and cost is high, and operating environment and skill set requirements is high, meanwhile, no matter the former or the latter, all there is the problem that assembly process is cumbersome, efficiency of assembling is low.
For the problems referred to above, it is necessary to propose the bearing block of a kind of new construction so that it is simple to operate, easy to assembly, efficiency of assembling is high, and assembling quality is good.
Utility model content
In view of this, the purpose of this utility model is in that to provide a kind of quick change bearing block, to solve the problem that assembling is of poor quality and the efficiency of loading and unloading is low that prior art exists.
For reaching above-mentioned purpose, this utility model provides following technical scheme:
A kind of quick change bearing block, including the pedestal with bore and the bearing being fixed in bore, be provided with floating structure between described bore and bearing, described floating structure include multiple be continuously arranged in described bore circumferentially by fasten described bearing tensioner utricule and for described tensioner utricule provide tensioner medium hydraulic system.
Further, described tensioner utricule includes bag and the bag fixed block being fixed on described bag, the circumference of described bore is evenly arranged with and described bag fixed block fixed block draw-in groove one to one, two sidewalls of described fixed block draw-in groove are provided with insertion tapering along the axis direction of bore, and described bag fixed block is fastened on fixed block draw-in groove by described insertion tapering.
Further, described insertion tapering is 3-10 °.
Further, it is interconnected between described bag.
Further, described hydraulic system includes the hydraulic pump and the medium pool that are connected by fluid pressure line with described tensioner utricule.
Further, described hydraulic system also includes the Pressure gauge that is arranged on fluid pressure line.
The beneficial effects of the utility model are in that:
This utility model by hydraulic system make tensioner utricule shrink and expand, can Quick fastening or unclamp bearing complete assembly or disassembly operation, its operation is few, efficiency is high, simultaneously as tensioner utricule is arranged in the circumference of bearing, bearing is made circumferentially to deform unanimously, circularity keeps, and assembling quality is high.
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, this utility model provides drawings described below to illustrate:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structure chart of fixed block draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
nullAs shown in the figure，A kind of quick change bearing block in the present embodiment，Including the pedestal 1 with bore and the bearing 2 being fixed in bore，It is provided with floating structure between bore 1 and bearing 2，The floating structure of the present embodiment include multiple be continuously arranged in bore circumferentially by fastening bearing 2 tensioner utricule 3 and for tensioner utricule 3 being provided the hydraulic system 9 of tensioner medium，The number of tensioner utricule 3 can unrestricted choice as required，Very few stability is inadequate，Too much can increase it and add this cost，The tensioner utricule 3 of the present embodiment arranges three，It includes bag 4 and bag fixed block 5，Bag fixed block 5 and bag 4 are fixedly connected to form entirety，The circumference of bore is evenly arranged with and bag fixed block 5 fixed block draw-in groove 6 one to one，Two sidewalls of fixed block draw-in groove 6 are provided with insertion tapering 7 along the axis direction of bore，Bag fixed block 5 holds greatly entrance from insertion tapering，It is fastened on the small end inserting tapering，During replacing，By less axial force，Bag fixed block 5 can be exited from fixed block draw-in groove 6，Mounting or dismounting extremely convenient，The insertion tapering of the present embodiment is 3-10 °，Better clamping effect can be reached.
The present embodiment makes tensioner utricule shrink by hydraulic system and expands, can Quick fastening or unclamp bearing complete assembly or disassembly operation, its operation is few, efficiency is high, simultaneously, owing to tensioner utricule is crossed in the circumference being evenly arranged in bearing, making bearing circumferentially deform unanimously, circularity keeps, and assembling quality is high.
As the improvement of the present embodiment, being interconnected between three bags 4, the pressure making tensioner medium in different bag 4 is consistent, forms balanced pressure system, it is ensured that unified chucking power, makes bearing deformation in the circumferential consistent, reaches better clamping effect and assembling quality.
Improvement as the present embodiment, hydraulic system 9 includes the hydraulic pump (not shown) and the medium pool (not shown) that are connected by fluid pressure line with described tensioner utricule 3, by hydraulic pump, tensioner utricule 3 is provided the tensioner medium of enough pressure, reach scheduled pressure value, meanwhile, fluid pressure line arranges Pressure gauge 8, it is possible at any time the pressure in tensioner utricule 3 is monitored, prevent hypotony clamping shakiness from causing danger, be conducive to improving the reliability of its use and safety.
This bearing block also has the advantage that
1, without holding bearing cap, part is few；
2, can quickly loading mill bar, efficiency of assembling is high；
3, different support pressure can be realized by the implant of adjustment variable concentrations and viscosity, to realize different flying ability, adapt to different use environment.
What finally illustrate is, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from this utility model claims limited range.
