Abstract
The utility model relates to a forward thrust bearing for a through-flow type hydraulic generator. The forward thrust bearing is characterized in that a fixed annular plate with a central hole is mounted on the inner side of an annular oil groove of a main shaft runner plate; a positioning pin is vertically mounted on the fixed annular plate; a forward thrust pad of the main shaft runner plate is movably mounted on the positioning pin; a spherical support pin is mounted on the side wall of the oil groove and in the central hole of the fixed annular plate; threads are formed on the cylindrical surface of the spherical support pin; a hexagonal head is formed at the outer end of the spherical support pin; a threaded sleeve matched with the threads of the spherical support pin is fixedly mounted on the side wall of the oil groove; the fixing flange of the threaded sleeve is mounted on the outer side of the oil groove; and the fixed clamping board with the hexagonal head of the spherical support pin and a fastening bolt are mounted on the mounting flange. Therefore, the position of the forward thrust pad can be adjusted flexibly by rotating the spherical support pin, so as to meet the precision requirements of the thrust bearing very conveniently; and the utility model further has the advantages of reasonable, simple and compact structure, easy operation, and safe and reliable operation.
Description
Technical field
The utility model relates to a kind of thrust-bearing that is used for the hydraulic turbine generator main shaft, especially a kind of positive axial thrust bearing of tubular-turbine generator.
Background technique
Vertical hydrogenerator thrust bearing segment working surface is a horizontal positioned, the workman can arrive and adjust every watt stressed (every watt of load of bearing) in the oil groove during installation, and tubular-turbine generator is horizontal unit, the working surface of its thrust bearing shoe is vertically to place, the bearing oil groove size can not be very big, the people can not enter the carrying of adjusting in the oil groove watt during installation, the therefore general stressed adjusting method of carrying out positive thrust watt in the oil groove outside that adopts.The structure of the positive axial thrust bearing of present most scaled bulb tubular hydraulic generators is: the fixedly ring flat-plate that has center hole in the annular oil groove installed inside of main shaft runner plate, fixedly be vertically installed with locating stud on the ring flat-plate, on locating stud, be movably installed with main shaft runner plate positive thrust watt, at the oil groove sidewall with fixedly in the pipper sphere support pin is installed, sphere support pin rear end is shaped on flange, between flange and the oil groove Steel Washer is installed, is evenly equipped with fastening screw trip bolt on the flange.The length machining error method that remedies positive thrust tilt sickness and sphere support pin of this structure is to guarantee all positive thrusts watt in one plane (promptly consistent with main shaft runner plate gap) by the thin and thick size of adjusting Steel Washer.But, the thin and thick size of Steel Washer is measured by " depth chi " this measurer, and the validity of " depth chi " has only 1/10mm, so the thickness that can't guarantee every positive thrust oil film watt when the main shaft runner plate moves evenly (oil slick thickness has only 0.05-0.07mm).Therefore the stressed precision between adjusting watt is difficult to reach the bearing requirement, can not satisfy the program requirement that thrust bearing segment " is beaten stressed ", thereby influence unit safety and reliability.
Summary of the invention
The utility model provides a kind of positive axial thrust bearing of simple to operate, tubular-turbine generator that precision is high 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:
A kind of positive axial thrust bearing of tubular-turbine generator, the annular oil groove that comprises the main shaft runner plate, be installed in the fixedly ring flat-plate that the annular oil groove inboard has center hole, be vertically mounted on the locating stud on the fixing ring flat-plate, be movably arranged on the main shaft runner plate positive thrust watt on the locating stud, be installed in oil groove sidewall and the fixing sphere support pin in the pipper, and the sphere support pin fixed block that is installed in the oil groove outside, be shaped on screw thread on the cylinder of described sphere support pin, sphere support pin outer end is shaped on six square toes, be fixed with thread bush on the oil groove sidewall with sphere support pin screw thread coupling, described fixed block is the fastening flange that thread bush is installed in the oil groove outside, and the fixing chuck plate and the fastening screw trip bolt of sphere support pin six square toes is installed on the fastening flange.
The utility model can also adopt following technological scheme:
Described clamp lower end is shaped on the bayonet socket with sphere support pin six square toes coupling, and the clamp upper end is shaped on the curve bath of fastening screw trip bolt.
Advantage and the good effect that the utlity model has are:
Owing on the cylinder of sphere support pin, be shaped on screw thread, be fixed with thread bush on the oil groove sidewall with sphere support pin screw thread coupling, the fastening flange of thread bush is installed in the oil groove outside, the fixing chuck plate and the fastening screw trip bolt of sphere support pin are installed on the fastening flange, just can adjust the position of forward thrust bearing shoe valve neatly by rotating the sphere support pin like this, thereby satisfy the required precision of thrust-bearing, easily; The utility model also has compactness rational in infrastructure, simple, easy operating, advantage safe and reliable to operation in addition.
