Abstract
The utility model discloses a sliding bearing structure of a water turbine, which comprises a bearing body and a bearing bush which are sheathed on a main shaft, and a rotating oil box and a lubricating oil circulating system which are fixedly connected on the main shaft, wherein the rotating oil box consists of a bottom support ring, a side oil box body and a top oil box cover; and the oil box body is of an integral structure. The sliding bearing structure of the water turbine is long in working life, avoids leakage, and is convenient in production and installation.
Description
Technical field
The utility model relates to a kind of water turbine sliding bearing structure.
Background technique
Water turbine is generally quite high to the requirement of sliding bearing as large-scale power generating equipment; Because the sliding bearing on the water turbine is in the state of running up for a long time; The wearing and tearing of sliding bearing are comparatively serious, and because rotating speed is fast, temperature is also higher; Under so abominable operating mode, sliding bearing structure of the prior art is easy to cause the generation of oil leakage phenomenon; Sliding bearing structure of the prior art generally is made up of the bearing support that is coated at main shaft and bearing shell and rotation oil box, and rotation oil box particularly of the prior art generally is made up of with the oil box body the oil box lid, for the ease of installation with process; Its oil box body is divided into two sections settings; Section between two sections oil box bodies is in rotation oil box side, and the side of rotation oil box also is its direction that receives lubricating oil centrifugation power, therefore; The processing request of its section is higher, and long-time the use is easy to produce leakage of oil.
The model utility content
In view of this, the purpose of the utility model is to provide a kind of water turbine sliding bearing structure that can prevent effectively that oil leakage phenomenon from producing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of water turbine sliding bearing structure comprises the bearing support and the bearing shell that are coated on the main shaft, is fixedly linked in rotation oil box and oil circulation system on the main shaft; Said rotation oil box is made up of the filler ring of bottom, the oil box body in the outside and the oil box lid at top; Said oil box body is an overall structure.
Further, be provided with labyrinth seal between said oil box lid and the bearing shell.
Further, between said filler ring and the main shaft be interference fit.
The beneficial effect of the utility model is: the oil box body of a kind of water turbine sliding bearing structure of the utility model is an overall structure, and the rotation oil box outside does not have the section of branch, is difficult for producing and leaks, and is convenient to produce long working life is installed.
Description of drawings
Fig. 1 is a kind of water turbine sliding bearing structure schematic representation of the utility model.
Embodiment
As shown in Figure 1, a kind of water turbine sliding bearing structure, comprise the bearing support that is coated on the main shaft 12 with bearing shell 3, be fixedly linked in rotation oil box and oil circulation system on the main shaft 1; Said rotation oil box is made up of the filler ring 6 of bottom, the oil box body 5 in the outside and the oil box lid 4 at top; Said oil box body 5 is an overall structure.
As shown in Figure 1, be provided with labyrinth seal between said oil box lid 4 and the bearing shell 3; Be interference fit between said filler ring 6 and the main shaft 1.
Above embodiment only is used to explain the utility model, but not is used to limit the utility model.
