Abstract
The utility model discloses a propulsion radial bearing end cover sealing device structure, comprising an end cover, an oil retaining ring and an oil throwing ring, wherein the inner end face of the end cover of the propulsion radial bearing is provided with the oil retaining ring composed of a ring and a circular ring; the end cover is connected with the oil retaining ring to form an annular groove; the outer end face of the propulsion disk is connected with the oil throwing ring which is lager than the annular groove and connected with the propulsion disk integrally. The propulsion radial bearing end cover sealing device structure has simple and novel structure, and can eliminate lubricant leakage without any sealing elements, to avoid leakage in operation, which is suitable for the propulsion radial bearing end cover seal of different mixed flow horizontal hydraulic turbines.
Description
Technical field
The utility model relates to the thrust of mixed flow horizontal water turbine, and is particularly relevant with the end bracket enclosed apparatus structure of thrust.
Background technique
The sealing means that the sealing of the thrust of present domestic mixed flow horizontal water turbine generally adopts bearing (ball) cover cushioning felt or other material to compress; but being sealed in the equipment running process of this structure; because of the felt that is used to seal along with the operation moisture absorption of equipment is saturated; the felt face that rubs mutually with the axial plane contact is also smooth gradually; it is big that gap between axial plane and felt also becomes gradually; lubricant oil is from the sealed at both ends seepage of bearing when making equipment operation; this not only causes working environment dirty, and needs to shut down replacing felt and make-up oil.
Summary of the invention
For overcoming the deficiency that existing thrust end bracket enclosed exists, the utility model provides a kind of improved thrust end bracket enclosed structure.This end bracket enclosed apparatus structure is simple, does not need any Sealing just can eliminate the phenomenon of oil seepage, realizes the purpose that the equipment operation oil dripping does not leak.
The technical solution of the utility model: this device comprises end cap, flinger ring, disc, on the end cap interior edge face of thrust flinger ring is arranged, flinger ring is made up of an annulus and ring, end cap and flinger ring are connected to form a circular groove, be connected with disc on the thrust disc exterior edge face, disc fuses greater than circular groove and thrust disc.
Annulus of described flinger ring and ring, its internal diameter all internal diameter with end cap is identical, and the external diameter of ring is bigger than the external diameter of annulus.
The overlapping dimension 20mm of described disc and flinger ring～25mm.
Effect of the present utility model: when equipment operation, bearing oil can drop on the disc, and drop on by the gap between disc and end cap in the groove of flinger ring, and finally overflow automatically in the inflow fuel tank, so move in circles, thereby eliminate the phenomenon of oil seepage, realize the purpose that the equipment operation oil dripping does not leak.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the thrust sectional structure chart of HL110-WJ-60 water turbine.
Embodiment
With reference to Fig. 1, this thrust end bracket enclosed device comprises end cap 1, flinger ring 2, disc 3.The utility model is to set up a flinger ring 2 on the interior edge face of thrust left and right sides end cap 1, flinger ring 2 is made up of an annulus and ring, its internal diameter all internal diameter with end cap is identical, the external diameter of ring is than the big 10mm～14mm of external diameter of annulus, end cap and annulus and ring are welded to connect and are integral, and make and form a circular groove between end cap and the ring; Set up a disc 3 in the exterior edge face of thrust disc, its internal diameter is greater than ring, and disc fuses greater than circular groove and thrust disc; Disc 3 is 20mm～25mm with the overlapping dimension of flinger ring 2.When equipment operation, bearing oil fast rotational along with axle from the gap of low thrust dish and bearing shell is constantly being splashed in the bearing support chamber under the centrifugal action all around, splash lubrication oil constantly drops on the disc 3 under the effect of deadweight, and drops in the groove of flinger ring 2 by the gap of 1 of disc 3 and end cap; Oil in flinger ring 2 grooves crossheading under the effect of deadweight drops on disc 3 inwalls, oil on the inwall can only keep certain thickness oil reservoir under centrifugal action, when core intersection surpasses, will overflow automatically and flow in the fuel tank, so move in circles, thereby eliminate the phenomenon of oil seepage, realize the purpose that the equipment operation oil dripping does not leak.The utility model is applicable to the thrust end bracket enclosed of the mixed flow horizontal water turbine of each range of models.
Claims (3)
1, a kind of thrust end bracket enclosed apparatus structure, it is characterized in that: this device comprises end cap, flinger ring, disc, on the end cap interior edge face of thrust flinger ring is arranged, flinger ring is made up of an annulus and ring, end cap and flinger ring are connected to form a circular groove, be connected with disc on the thrust disc exterior edge face, disc fuses greater than circular groove and thrust disc.
