Abstract
The main purpose of the utility model is to disclose an elastic metal-plastic tile thrust bearing supported by the hydraulic palace-lantern-shaped elastic oil tank. The supporting structure of the hydraulic palace-lantern-shaped elastic oil tank is a single layer of elastic metal plastic tile thrust bearing which is composed of an elastic metal-plastic composite layer and a steel tile base layer. The elastic metal-plastic composite layer is obtained by firmly combining the polytetrafluoroethylene and copper wire with a special technique and is brazed on the steel tile base layer to compose an elastic metal-plastic tile. The supporting structure is the hydraulic palace-lantern-shaped elastic oil tanks installed at the lower part of the steel tile base layer. The elastic oil tanks are connected with each other through the hydraulic pipes. The palace-lantern-shaped elastic oil tanks are fixedly installed on the bearing base uniformly along a ring shape. The utility model has the advantages of simple installation and maintenance, high allowed unit pressure, long allowed accidental water breaking time of the cooling water, reduced attrition, insulation effect and large bearing capacity.
Description
Technical field
The utility model relates to a kind of hydraulic pressure palace lantern shape toroidal membrane support elastic metal-plastic watt thrust-bearing.
Background technique
Thrust-bearing is one of most important parts in the hydraulic generator unit, and it is bearing electric generating set rotor weight and axial hydraulic thrust, and can its service behaviour not only is directly connected to unit safe operation, but also influences exerting oneself and efficient of unit.Along with the raising of hydraulic generator unit operational reliability, also just high more to the requirement of thrust-bearing.Adopting new tiling material, new thrust-bearing tile structure and supporting structure and preferred bearing structure parameter is the effective way that addresses this problem.
Summary of the invention:
The purpose of this utility model is to disclose a kind of hydraulic pressure palace lantern shape toroidal membrane support elastic metal-plastic watt thrust-bearing, related position is the large and medium-sized hydraulic generator thrust bearing in the oil lubrication environment, by the improvement of thrust-bearing tile structure and supporting structure, reach the purpose of improving the thrust-bearing performance.The purpose of this utility model is to realize by following structure: a kind of hydraulic pressure palace lantern shape toroidal membrane support elastic metal-plastic watt thrust-bearing, hydraulic pressure palace lantern shape toroidal membrane supporting structure is the individual layer Plastic Thrust Bearing, the individual layer Plastic Thrust Bearing is made up of elastic metal-plastic composite bed and steel tile base layer, the elastic metal-plastic composite bed is by teflon, copper wire through the special process combination firmly, and be soldered on the steel tile base layer, constitute elastic metal plastic tile, supporting structure is the hydraulic pressure palace lantern shape toroidal membrane that install steel tile base layer bottom, toroidal membrane is interconnected by hydraulic tube, and palace lantern shape toroidal membrane is fixedly mounted on the bearing support along annular is uniform.Advantage of the present utility model is: install, overhaul simple; Allowance unit pressure height; Do not need the high pressure oil jacking system; Allow cooling water accident time of cutting off the water supply long; Reduce wear; Insulating effect is arranged; Bearing capacity is big.Palace lantern shape toroidal membrane has the ability of load between in unit running process autobalance watt, watt the load uniformity≤3%, watt inclination flexibly and can control advantage such as watt distortion preferably.For large and medium-sized thrust bearing, be applicable to fields such as large and medium-sized hydraulic turbine generator.
