Abstract
The double-rotation water-lubricated thrust bearing suitable for hydroelectric generator and rotary slide bearing is composed of thrust head and mirror plate, rotary plate, thrust bush, and supporters. Said totary plate is composed of elastic metal-plastic bush and antiwear, anticorrosion, high-strength mirror plate made of stainless steel. The rotation speed of rotary plate is slower than that of thrust head and mirror plate due to friction, resulting in damping the speed of the latter two elements to elongate the service life of thrust bush.
Description
The present invention relates to a kind of reversible rotation type water lubricating bearing, be applicable to water energy generator and rotary sliding bearing.
Existing thrust-bearing mainly is by thrust bearing shoe valve and runner plate at oil lubrication, oil cooling but, forms film lubrication between thrust bearing shoe valve and runner plate and rotates, and water plays indirect cooling action hereinto.
Reversible rotation type water lubricating thrust bearing of the present invention is to add a swivel plate in existing thrust-bearing; Just add a swivel plate between runner plate and thrust bearing shoe valve, when runner plate rotated, because of friction is arranged, swivel plate also rotated, but the swivel plate rotating speed will be slower than runner plate, the origin of Here it is double-rotation type.Its effect is the rotating speed that reduces between thrust bearing shoe valve and runner plate, reduces the hot abrasion of thrust bearing shoe valve, prolongs the working life of thrust bearing shoe valve; Water rises lubricated in reversible rotation type water lubricating thrust bearing and directly cooling action, and is pollution-free.
Swivel plate is a plate that is combined into by thrust bearing shoe valve 4 and runner plate 5 in Fig. 1, the material of runner plate 5 is wear-resisting, corrosion-resistant, high-intensity stainless steels, the thickness of runner plate is by the load decision, 5 one-tenth of runner plates are L shaped, and 12 one-tenth shapes are arranged in the L shaped vertical surface, have the hole in shape, its material is a high strength, and corrosion resistant stainless steel is made.The outside of runner plate 5 is minute surfaces, and the degree of finish △ of minute surface is more than 10, planeness≤0.015, perpendicularity between minute surface≤0.1.
Thrust bearing shoe valve 4 is elastic metal plastic tiles, and an elastic metal plastic tile steel watt primary surface has the corrosion resistant stainless protection layer of one deck, and 4 ends of thrust bearing shoe valve seat has
, have in the face of the thrust bearing shoe valve of doing 4 in the runner plate 5
, be fixed on the runner plate 5 by stationary fit, so just form swivel plate, thrust bearing shoe valve 4 can be single watt, also double watt, every watt the discrepancy in elevation≤0.005.
It is load decision by guide bearing that the L shaped vertical surface of swivel plate runner plate 5 has the thickness of shape 12,12 and width.Guide bearing 11 also is an elastic metal plastic tile; an its steel watt primary surface has one deck corrosion-resistant stainless steel protective layer; sit and fix with screw rod at the end of guide bearing 11; screw rod passes 12 shape holes; fix with nut; the gap of guide bearing is regulated by nut, and screw rod, nut all are high strength, and corrosion resistant stainless steel material is made.The L shaped appropriate location perforate of runner plate 5, the size in hole, close rare all by coolant-temperature gage and flow decision.
In conjunction with the accompanying drawings invention is described in detail
