Abstract
The utility model relates to an automatic aligning type guide bearing structure comprising a guide bearing shoe and a support body. The automatic aligning type guide bearing structure is characterized in that a ball seat is arranged between the guide bearing shoe and the support body, ball surface matching is adopted between the ball seat and the bearing shoe; the end part of the ball seat is provided with a flange; and the flange of the ball seat is fastened on the support body by a fastening piece. Therefore, when the generator adopting the structure operates, with the change of the axial line, the two ball surfaces are driven to generate relative displacement, therefore, automatic alignment of the guide bearing shoe is realized, the shock resistance is good, and the stability of the generator in operation is improved. In addition, the automatic aligning type guide bearing structure also has the advantages of compact structure, convenient installation and disassembly, and the like.
Description
Technical field
The utility model belongs to horizontal axis tubular-turbine generator technical group field, particularly relates to a kind of self-centering type guide bearing structure.
Background technique
At present, in horizontal axis tubular-turbine generator group, generator pilot bearing is between generator and water turbine, as the main support of bearing generator set rotating part weight and unilateral magnetic force.Generator set is in service, because load and the variation of unilateral magnetic force and the influence of water buoyancy, axis is in continuous variation, and generator pilot bearing must the adjustable axle heart changes with axis and adapts, thereby guarantees that generator set is stablized, the reliable operation.The self-aligning of existing generator pilot bearing is to be processed into the very little cylndrical surface of axial dimension by the external side of plate shaped guide bearing, and and the parts of spring bearing body between the gap left realize.This structure has axial clearance again because supporting surface is little, and operation stability is poor, and the easy leakage of oil of gap location, pollutes generator amature and stator coil.
Summary of the invention
The utility model provides a kind of compact structure, self-centering type guide bearing structure easy to install for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Between described guide bearing and the support ball seat is installed, adopts sphere to cooperate between ball seat and the guide bearing, the ball seat end is shaped on flange, and the ball seat flange is fastened on the support by fastening piece.
The utility model can also adopt following technical measures:
The cylndrical surface is made at described ball seat inner peripheral surface axial direction two ends, and the spill sphere with protruding sphere coupling is made in the centre.
The cylndrical surface is made at described ball seat inner peripheral surface axial direction two ends, and the spill sphere with protruding sphere coupling is made in the centre.
Leave 0.5～0.6 mm clearance between the cylndrical surface at described guide bearing two ends and the cylndrical surface at ball seat two ends.
Between the protruding sphere of described guide bearing and the spill sphere of ball seat position-limitting pin is installed.
Between the protruding sphere of described guide bearing and the spill sphere of ball seat Stamping Steel Ribbon is installed.
Advantage and the good effect that the utlity model has are: owing to adopt concavo-convex sphere to cooperate between guide bearing and the ball seat, in the generator operation,, impel between two spheres to produce relative displacement along with the variation of axis, thus the self-aligning of realization guide bearing.Two spheres cooperate area big, and antivibration is good, thereby improve the stability of generator operation.Because ball seat cylindrical place adopts the cylndrical surface, can accomplish not dismantle whole bearing arrangement simultaneously, can use the special bricklayer tool of tearing open that ball seat is extracted out with guide bearing, overhaul, convenient and swift; Concavo-convex in addition sphere cooperation place is provided with Stamping Steel Ribbon, has improved sealability, has avoided lubricant pollution generator unit stator and rotor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. support 2. ball seat 2-1. flanges 3. guide bearings 4. bolts 5. position-limitting pins 6. Stamping Steel Ribbons.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of self-centering type guide bearing structure, comprise guide bearing 3, support 1, between described guide bearing 3 and the support 1 ball seat 2 is installed, adopt sphere to cooperate between ball seat 2 and the guide bearing 3, ball seat 2 ends are shaped on flange 2-1, and the flange 2-1 of ball seat 2 is fastened on the support 1 by fastener bolt 4.In the said structure: the cylndrical surface is made at described ball seat 2 inner peripheral surface axial direction two ends, and the spill sphere with protruding sphere coupling is made in the centre.The cylndrical surface is made at described ball seat 2 inner peripheral surface axial direction two ends, and the spill sphere with protruding sphere coupling is made in the centre.Adopt concavo-convex sphere to cooperate like this between guide bearing 3 and the ball seat 2, in the generator operation,, impel between two spheres to produce relative displacement along with the variation of axis, thus the self-aligning of realization guide bearing.Two spheres cooperate area big, and antivibration is good, thereby improve the stability of generator operation.Because ball seat cylindrical place adopts the cylndrical surface, can accomplish simultaneously, not dismantle whole bearing arrangement, can use the special bricklayer tool of tearing open that ball seat is extracted out with guide bearing, overhaul, convenient and swift; Leave 0.5～0.6 mm clearance between the cylndrical surface at described guide bearing 3 two ends and the cylndrical surface at ball seat 2 two ends, the utility model adopts 0.5 millimeter, and this gap guide bearing and ball seat when preventing that the self-aligning deflection angle is big are collided.Between the protruding sphere of described guide bearing and the spill sphere of ball seat position-limitting pin is installed, is used to limit the guide bearing circumferencial direction and rotates.Between the spill sphere of protruding sphere and ball seat Stamping Steel Ribbon is installed, prevents that pressure oil from rushing down outward, improved sealability, avoided lubricant pollution generator unit stator and rotor.
