Description
Technical field
The utility model relates to a kind of roller devices for rotary machine centering, belongs to roller field, particularly relates to a kind of stiffness variable flexible roller device for rotary machine centering.
Background technology
Rotary machine is widely used in the industries such as petrochemical industry, metallurgy, coal and machining, be generally by be arranged on one or more concentric circular tracks upper rotary workbench, power set and several form for the roller devices of feeling relieved, supporting.Roller devices is distributed in side in or beyond track, tangent with track, and the common gyroaxis forming rotary machine.In the course of work, workbench wraparound rotating shaft revolution under power set drive runs, require the active force of roller and track little as far as possible reducing equipment energy consumption, reduce compressive plane and to wear and tear and equipment shakes, when the radial displacement simultaneously caused when track out-of-roundness and workbench dynamic deflection reaches certain numerical value, roller devices can produce rapidly huge reaction force and make workbench Rapid reset, completes flexible bit shift compensation.In addition, supporting track often causes diameter to change because of operating temperature and variation of ambient temperature, thus causes track counter roller to produce radial displacement, and roller devices also needs to provide rigid displacement to compensate for this reason, thus makes roller again reach ideal position.
Roller devices conventional at present mainly contains following several:
Rigid support roller devices is fixed on installation frame by roller by fixed forms such as securing member or welding such as bolts, this roller devices structure is simple, at the bottom of cost, but scroll wheel positions rigidly fixes, bit shift compensation cannot be realized, once track radial displacement reaches certain numerical value, to severe crush be there is in track and part roller, cause equipment to shake, thus cause reduce equipment life, even directly damaged.
The roller devices adopting high-voltage oil cylinder to make bit shift compensation has bit shift compensation advantage flexibly, but it need be equipped with the servicing units such as Hydraulic Station,
equipmentcontour structure size is large, and cost is high, and in equipment running process, maintenance and management is loaded down with trivial details.
The roller devices adopting helical spring to make bit shift compensation also can be track radial displacement provides flexible compensation, but because helical spring is rigidity of fixation coefficient, when required support force is larger, required helical spring appearance and size is comparatively large, or could meet support requirement by larger displacement; Once workbench offsets, roller devices can not produce rapidly huge reaction force and make its Rapid reset, thus cannot meet the higher rotating accuracy requirement of workbench.
Utility model content
In order to solve the roller devices Problems existing for feeling relieved in existing rotary machine, the utility model provides a kind of stiffness variable flexible roller device for rotary machine centering, there is the advantages such as cost is low, size is little, convenient mounting or dismounting maintenance, larger load can be produced with less deformation, thus rapidly flexible compensation is carried out to the radial displacement caused because of track out-of-roundness and workbench dynamic deflection etc., simultaneously race way diameter can be caused to change to variations in temperature and rigid compensation is carried out in the displacement that produces.
The utility model solves the technical scheme that its technical problem adopts:
A kind of stiffness variable flexible roller device for rotary machine centering, comprise base, roller, roller shaft and rolling wheel support, rolling wheel support top and the bottom are equipped with U-lag and blend stop, described roller shaft is detachably fixed on rolling wheel support by blend stop, described roller devices is also provided with elastic mechanism, governor motion and fixed mechanism, described elastic mechanism comprises elastic parts and locating shaft, described governor motion comprises adjustment gripper shoe, at least two are symmetrically set in the first locking nut regulating the guide-localization bolt in gripper shoe and be positioned on guide-localization bolt, first adjusting nut, second adjusting nut and the second locking nut, described adjustment gripper shoe central authorities are provided with the circular hole with locating shaft adaptation, locating shaft is fixed on rolling wheel support sidepiece, and successively through elastic parts and adjustment gripper shoe, on described rolling wheel support, adjustment gripper shoe and fixed mechanism, correspondence is equipped with pilot hole, guide-localization screw bolt passes rolling wheel support, adjustment gripper shoe and fixed mechanism, described first locking nut and the first adjusting nut lay respectively at and regulate outside gripper shoe and inner side, and the second locking nut and the second adjusting nut lay respectively at outside fixed mechanism and inner side.Gripper shoe is regulated to have supporting role to elastic parts, can be elastic parts by regulating the first adjusting nut and predeformation is provided, when skew occurs the centre of gyration or the track radial displacement that causes of track out-of-roundness is less, provide the less flexible bit shift compensation of opposite direction by the predeformation part of elastic parts for equipment.By regulating the second adjusting nut, adjustment gripper shoe, elastic parts, rolling wheel support and roller can be made simultaneously along guide blot translation, thus the rigid displacement completing pair roller device compensate.
As preferably, described guide blot is provided with four.
As preferably, described elastic parts is combined by one or more of the tapered coil spring of variable rigidity, nest scroll helical spring, disk spring, flat spring and flat spring, can produce different rigidity to different displacement.
More preferably, described elastic parts is disk spring, variable rigidity, and buffering vibration absorption ability is strong, and can bear large load with small deformation, requisite space is less, adopts simultaneously and combinationally uses, have maintenance, change the outfit advantage easily.
As preferably, described fixed mechanism is welded by a fixed head and two gussets and forms, and described fixed mechanism is weldingly fixed on base.
The operation principle of this roller devices is: time less when the revolving dial centre of gyration skew occurs or causes track radial displacement because of track out-of-roundness, realize bit shift compensation by the predeformation part of elastic parts; When radial displacement is greater than predeformation part, one side wheel and track depart from, and toss about roller and track produce and extrude, squeezing action power is delivered on elastic parts by turning rolls, cause elastic parts to be out of shape and produce huge reaction force rapidly, make track and revolving dial do reverse displacement, thus provide flexible bit shift compensation for equipment, finishing equipment resets.
When operating temperature or environment temperature change, supporting track produces radial displacement because the difference of line swell increment causes race way diameter to change, roller and orbital distance are changed, now can open the first locking nut and the second locking nut, and by adjustment second adjusting nut, make turning rolls translation on guide blot, make roller again reach ideal position, realize rigid displacement to compensate, thus the equipment of guarantee obtains higher rotating accuracy.
The beneficial effects of the utility model are:
1, roller devices provided by the utility model, has the advantage that structure is simple, with low cost, size is little and convenient mounting or dismounting are safeguarded.
2, adopt the elastic parts of variable rigidity, when prescribed limit intrinsic displacement, the change of its support force is less, little to contact surface abrasion; When displacement exceedes prescribed limit, large load can be produced with small deformation, make device reset rapidly, namely carry out the flexible bit shift compensation of stiffness variable.
3, when work and variation of ambient temperature, can change to supporting track diameter the radial displacement caused and carry out rigid displacement compensation.
