Abstract
The utility model relates to an engineering plastics compound floating tile for an impeller type turbine oil supply head. In the structure of the utility model, a cylindrical frame is made from a material with enough strength and rigidity; a layer of engineering plastics is fixedly adhered to the inner wall of the cylindrical frame; an arresting pin hole is arranged on the bottom end face of the cylindrical frame. In the utility model, the engineering plastics which has the advantages of self-lubricating property, small friction coefficient, good wear resistance and no wear to a main shaft is taken as a wear-resistant layer; the cylindrical frame is made of metal or fiber glass reinforced plastics, playing a role of a supporting frame to guarantee enough rigidity, strength and size stability of all parts; and the stop pinhole is used for containing an arresting pin. The utility model can maintain long stability of the clearance between a shaft and a shaft bushing, therefore the utility model has small oil leakage quantity and long service life and the original necessary replacement in maintenance each time is changed and extended to a plurality of expanded general repair.
Description
Affiliated field: the utility model relates to a kind of bearing shell, compound unsteady watt of particularly a kind of Combinatory for adjustable blade propeller turbine engineering plastics.
Background technique: unsteady watt of present home and abroad Combinatory for adjustable blade propeller turbine as shown in Figure 1, all adopt casting tin bronze ZQSn5-5-5 or ZQSnP10-1 made, watt serious wear of floating is in operation, each maintenance all need be changed because wearing clearance increases, the leakage of oil amount increases, and causes the oil pump frequent starting of oil gear, draws burden for the operation maintenance band of unit, increase the operating cost of complete machine, expended a large amount of Cuprum alloys on the other hand.Draw following result according to research: the unsteady bearing shell of casting tin bronze is not suitable for Combinatory for adjustable blade propeller turbine, wearing and tearing takes place be inevitable.
Summary of the invention: the purpose of this utility model provides that a kind of simple in structure, good seal performance, anti abrasive Combinatory for adjustable blade propeller turbine engineering plastics are compound floats watt.The purpose of this utility model realizes by following structure: the utility model is compound unsteady watt of a kind of Combinatory for adjustable blade propeller turbine engineering plastics, cylinder frame is made of the material with sufficient intensity and rigidity, the cylinder frame inwall adheres to fixing one deck engineering plastics, is provided with limit pin hole on the bottom end of cylinder frame.The utility model uses engineering plastics as wearing layer, and its material is: nylon or be polyimide.Engineering plastics have self-lubricating property, and friction factor is little, and wear-resisting property is good, not wear spindle.Cylinder frame of the present utility model can use metal or use glass fibre reinforced plastics, plays the effect of support frame, guarantees that parts have enough rigidity, intensity and dimensional stability.Limit pin hole of the present utility model is used to hold position limit pin, and under the effect of position limit pin, unsteady bearing shell can only be radially mobile a little, and can not rotate.The utility model can retainer shaft and bearing shell between the gap long-term stability constant, thereby the leakage of oil amount is little, long service life must be changed by original each maintenance, changes into and can extend to several expansion overhauls.
