Abstract
The utility model discloses a guide bearing structure for a hydraulic generator, which comprises a lower frame 1, a guide bearing block 2 and a bearing seat 3, wherein the bearing seat 3 is fixed on the lower frame 1. The surface of the guide bearing block 2 is provided with a parabola oil groove 6 which is obliquely upward; the back of the guide bearing block 2 is connected with the bearing seat 3 through a spherical surface supporting column 4; the surface where the spherical surface supporting column 4 and the bearing seat 3 are contacted is provided with a shim set. The utility model is provided with an obliquely upward parabola oil groove on the guide bearing block surface and adopts a rigid supporting mode, and the supporting rigidity is improved; the utility model can adapt to the radial force changes of different operating conditions, and the lubricating effect can be improved. The utility model has the advantages of simple structure, strong carrying capacity, strong work condition adaptability, small abrasion, etc.
Description
Technical field
The utility model relates to a kind of Hydraulic generator pilot bearing structure.
Background technique
Because hydraulic turbine generator is dragged by the impulse turbine of high head, head changes greatly, and water turbine has the requirement of single nozzle operating conditions, and radial load is big.Particularly when the single nozzle operating conditions, radial force will have bigger drift angle, and will be particularly outstanding to the influence that water is led and descended to lead.For adapting to Different Effects and the requirement of different operating modes to guide bearing, the structural design of guide bearing is very fastidious, watt supporting way and position, each parameter that molded lines etc. influence greasy property has all required a reasonably coupling.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Hydraulic generator pilot bearing structure is provided, and to adapt to the different requirements of different operating modes to guide bearing, is applicable to high-speed high capacity hydraulic generator unit.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of Hydraulic generator pilot bearing structure comprises lower bearing bracket, guide bearing block, bearing support, and bearing support is fixed on the lower bearing bracket, it is characterized in that offering on the guide bearing block tiling parabola oil duct obliquely, and watt back of the body of guide bearing block is connected with bearing support by support pin of spherical end.
Guide bearing block is a non-concentric type elastomeric plastics watt, to reduce friction factor, improves bearing capacity and adaptive faculty.Guide bearing block adopts the reverse spherical support mode of rigidity, to improve support stiffness, to adapt to the variation of radial force under the different operating modes.Offer a parabola oil duct obliquely on the guide shoe face of guide bearing block, improve lubrication effect.
The surface of contact of support pin of spherical end and bearing support is provided with shim pack, to improve contact performance.
From above narration as can be seen: a kind of Hydraulic generator pilot bearing structure described in the utility model, offer parabola oil duct obliquely on the guide bearing block tiling, supporting way is reverse sphere rigid support, improve support stiffness, can adapt to the variation of radial force under the different operating modes, improve lubrication effect.The utlity model has advantages such as simple in structure, that bearing capacity strong, the operating mode adaptive faculty strong, wearing and tearing are little.
Description of drawings
Fig. 1 is a kind of Hydraulic generator pilot bearing section of structure.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing: as Fig. 1, a kind of Hydraulic generator pilot bearing structure, comprise lower bearing bracket 1, guide bearing block 2, bearing support 3, bearing support 3 is fixed on the lower bearing bracket 1, offer parabola oil duct 6 obliquely on guide bearing block 2 tilings, watt back of the body of guide bearing block 2 is connected with bearing support 3 by support pin of spherical end 4.
Support pin of spherical end 4 is provided with shim pack 5 with the surface of contact of bearing support 3.
Guide bearing block 2 is non-concentric type guide bearing block.
