Description
Technical field
The utility model relates to a kind of hydraulic turbine main shaft bearing, the turbine guide bearing of especially a kind of radially vertical pivot parabola of oil lubrication watt.
Background technique
The vertical turbine guide bearing mainly bears the rotating part radial force at present, does not radially wobble when making main axis rotation.The structure that the vertical turbine guide bearing is relatively more commonly used is the cartridge type bearing.The conventional construction of cartridge type bearing is: the main shaft bearing body is installed on water-turbine top cover, the bearing support upper end is equipped with top tank and fuel tank cap, the cooler of lubricant oil is installed in the top tank, the bearing support lower end is equipped with the rotation oil tray that rotates with main shaft, the bearing support lower end is shaped on the filler opening that is communicated with bearing shell, and the oil guide pipe that is communicated with oil tray and top tank is installed in the bearing support sidewall.Bearing support is generally branch half hitch structure, and bearing shell is formed by the Babbitt casting.Have oil groove on the bearing shell and reach radially oil inlet hole, when the rotation of main shaft and oil tray, oil forms static pressure in oil tray, enters bearing shell with oil inlet hole radially, along watt on oil groove rise to guarantee the lubricated of rubbing surface, flow back to fuel tank by the spill port on the bearing support then and form the oil circulation.This bearing generally need be installed in the part of main shaft enlarged diameter, but, temperature higher for linear velocity on the high head unit raises and frictional loss is bigger, so the cartridge type bearing is difficult to address these problems, and the situation of tile kilning often occurs.In addition, the cleaning of built-in cooler, cooling tube are changed very inconvenient.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be easy to dismantle, the turbine guide bearing of the radially vertical pivot parabola of oil lubrication easy to maintenance watt.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The turbine guide bearing of a kind of radially vertical pivot parabola of oil lubrication watt, comprise the annular shaft bearing that is installed on the water-turbine top cover, be fixed on the annular bearing body on the bearing support, be embedded in the main shaft bearing shell of bearing support inboard, be installed in the rotation oil tray that is positioned at the bearing support lower end on the main shaft, be welded at the top tank of bearing support upper end, the fuel tank cap of sealing top tank, and oil guide pipe and cooler lubricated and the cooling bearing shell, described bearing support is combined by the pintongs arc body, the bearing support upper end is shaped on and the bearing support flange connecting, described oil guide pipe is the pitot tube that is installed in the bearing support sidewall, the lower end of pitot tube is communicated with rotates oil tray, the upper end of pitot tube connects a cooler that is arranged on the top tank outside by pipeline, and the oil outlet of cooler is by the pipeline connection top tank.
The utility model can also adopt following technological scheme:
Described bearing shell is a pintongs, and its surface is a parabolic surface, and its thickness is along direction of a curve attenuation gradually.
Advantage and the good effect that the utlity model has are:
Because the bearing support distinguish combines, field-strip is more convenient.Its surface of bearing shell is a parabolic surface, has superior bearing dynamic hydraulic performance, and the lube oil cooler of peripheral hardware overhauls easily and cleans, and this bearing bush can need not have the part of axle journal or main shaft enlarged diameter directly facing to the axle journal that polishes on the main shaft; In addition the utility model also have simple in structure, be easy to make, advantage that bearing radial force is big.

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 6, annular shaft bearing 4 is installed on water-turbine top cover 2, be fixed with annular bearing body 5 on bearing support, this bearing support is combined by the pintongs arc body, and the bearing support upper end is shaped on and the bearing support flange connecting.Be inlaid with the bearing shell 20 of main shaft 10 in the bearing support inboard, this bearing shell is circumferentially uniform to form for pintongs and by the Babbitt casting, and its surface is a parabolic surface, and its thickness is along direction of a curve attenuation gradually.By snap ring 1 the rotation oil tray 3 that is positioned at the bearing support lower end is installed on main shaft, the fuel tank cap 12 of be welded in the bearing support upper end top tank 11 and sealing top tank is equipped with bearing cap 15 and observes and covers 13 on the fuel tank cap.Pitot tube 8 and pipe 14 are installed in the bearing support sidewall, the lower end of pitot tube is communicated with rotates oil tray, the upper end of pitot tube is connected a cooler 7 that is arranged on the top tank outside by pipeline with gland 9, cooler is installed on the bearing support by supporting plate 6, cooler filler opening 16 and pitot tube upper end pipeline connection, the oil outlet 19 of cooler is communicated with top tank by pipeline and gland.The cooling water outlet pipe 17 of cooler is connected water pump respectively with cooling water inlet pipe 18.Like this, because the bearing support distinguish combines, field-strip is more convenient.Its surface of bearing shell is a parabolic surface, has superior bearing dynamic hydraulic performance, and the lube oil cooler of peripheral hardware overhauls easily and cleans, and this bearing bush can need not have the part of axle journal or main shaft enlarged diameter directly facing to the axle journal that polishes on the main shaft; In addition the utility model also have simple in structure, be easy to make, advantage that bearing radial force is big.
Working principle:
Bearing is the self-loopa form, and all oil is included in the bearing, need not pump or external fuel tank.When static, all oil is all rotating 3 li of oil trays, and bearing shell 20 bottoms are immersed in the oil, do not need other fuel feeding before the startup.Oil level can be monitored by a hole on the bearing support 4.When main shaft 10 rotations, oil automatically circulates between rotation oil tray 3 and top tank 11.Pitot tube 8 in the rotation oil tray 3 is the oily inspiration and the top tank 11 that leads.Oil enters before the top tank 11, and oil flows back to through bearing support 5 from top tank 11 then and rotates oil tray 3 automatically from pitot tube 8 cooler 7 of flowing through.
