Abstract
The utility model relates to a suspended thrust bearing for a hydraulic turbine generator, which is composed of a thrust ring, a clamping ring, a clamping band, a positioning device, a thrust block, etc. The structure of a rotational freedom spherical pair and the positioning device are adopted by the automatic limiter for punching bearing cage. The clearance fit is adopted by the thrust ring and a main shaft, having the features of automatic straightening and simple assembly, and the automatic limiter for punching bearing cage has the advantages of the rapid regulation of the shaft line. The utility model is adapted for a suspension type electric generator set.
Description
The utility model technical field belongs to plant generator equipment, is a kind of suspending type hydraulic generator thrust bearing.
At present, no matter be the rigidity or the hydraulic generator thrust bearing of elastic structure pattern, install or the overhaul process in when adjusting axis, the general way that adopts is to repair to scrape the thrust collar bottom surface or repair the felt pad of scraping between thrust collar and the runner plate, perhaps adds paper washer between thrust collar and runner plate.Repair that to scrape thrust collar bottom surface workload big and loaded down with trivial details, scrape pad or cushioning not only the life-span short, and carry out repeatedly could be successful.Moreover, most transition fit or the interference fit of adopting of thrust collar and generator shaft.Brought certain difficulty for the mounting or dismounting thrust collar, need heat thrust collar during dress, need special tool when tearing open and need the long period.
The utility model is in order to overcome above-mentioned defective, rotating part to original suspending type hydraulic generator thrust bearing redesigns, change snap ring and thrust collar set of planes and be combined into the sphere combination, changing thrust collar and generator shaft interference fit is Spielpassung, realizes that the axis adjustment is simply quick.
The technical solution of the utility model is achieved in that this thrust-bearing is made up of thrust collar, snap ring, clip, positioning device etc., thrust collar is contained in the generator shaft upper end, snap ring with convex spherical is contained between the spill annulus sphere of the parallel circle ring key groove of main shaft upper end and thrust collar, thereby main shaft is suspended on the thrust collar.Clip is connected in the thrust collar upper-end surface with screw, and the inner hole sleeve of clip is on the step of main shaft upper end, and 8 positioning devices evenly are equipped with along circumference in the thrust collar the inside.
Have the spherical pair structure of rotational freedom because the convex spherical of snap ring and the spill sphere of thrust collar constitute, therefore, have following advantage: 1, withdraw from positioning device, in the middle of operation, have the automatic aligning function.Even the center of gravity of 2 hydraulic turbine generator rotating parts not on axis, so when main shaft is adjusted, does not need to resemble to repair traditional axis adjustment yet and scrapes combinating face or cushioning, only need operation positioning device or top guide bearing or lower guide bearing can reach the adjustment purpose.Has effect of saving time and labor.
Introduce the structure of model utility in detail below in conjunction with accompanying drawing
Fig. 1 is the model utility longitudinal sectional view.
Fig. 2 is the plan view of model utility.
Fig. 3 is that model utility is along A-A line sectional view.
Fig. 4 is that model utility is along B-B line sectional view.
Fig. 5 is the longitudinal sectional view of model utility thrust collar (1).
With reference to accompanying drawing: thrust collar (1) is sleeved on main shaft (4) upper end, thrust collar (1) bottom surface is dropped on the thrust bearing shoe valve (8), thrust collar (1) endoporus is a conical bore, constitute Spielpassung with main shaft (4), rotate with main shaft (4) by flat key (5), the flat key groove entry end of thrust collar (1) is the horn mouth shape, and being convenient to thrust collar (1) can be inserted in smoothly.Thrust collar (1) endoporus upper oral part is the annulus concave spherical surface, snap ring (6) in two, be fixed on 4 socket head screws (7) in the parallel circle annular groove of main shaft (4) upper end, the bottom of snap ring (6) is the protruding sphere of annulus, with the annulus concave spherical surface formation spherical pair structure of thrust collar (1).8 screws that evenly distribute in thrust collar (1) the inside are equipped with 8 positioning devices in the screw, positioning device is by positioning head (9), ball screw (10), and spring pad (11), lock screw (12) is formed.The existing positioning action of positioning device can adjust the usefulness of axis again.When adjusting axis, the screw of backing off (12), spring pad (11), operation ball screw (10) relatively moves the spherical pair between thrust collar (1) and the snap ring.After mixing up, 8 positioning heads (9) are held out against with ball screw (10), load onto spring pad (11) and lock screw (12).
The interior circle of clip (2) is a hierarchic structure; and be sleeved on the step of main shaft (4) upper end; be fixed on the upper-end surface of thrust collar (1) again by 8 socket head screws (3), it protects snap ring on the one hand, can be successfully with thrust collar (1) jack-up together when being convenient to the top rotor on the one hand.
