Abstract
In order to solve the problems that in the prior art, a bearing structure is complex in structure, can not carry out single-nozzle operation, a bearing bush is excessively large in stress, so that a bearing temperature of a water turbine rises and a unit can not carry out stable operation, the utility model provides an oil immersion cylinder type bearing structure of the water turbine. A cylinder type bearing which is of a split structure is sleeved on the outer side of a shaft collar of a main shaft, an oil passing hole is formed in the radial direction of a cylindrical surface, making contact with the cylinder type bearing, of the shaft collar, one end of the oil passing hole is communicated on a lower oil tank, the other end of the oil passing hole is communicated with the contact face between the shaft collar and the cylinder type bearing, a shaft collar hole is formed in the upper portion of the shaft collar, one end of the shaft collar hole is communicated with an upper oil tank, the other end of the shaft collar hole is communicated with an oil groove, an oil blocking ring is arranged in an oil groove in the inner side of the shaft collar, a cooler is arranged in the upper oil tank, and supporting components are arranged on the lower portion of the cylinder type bearing. The oil immersion cylinder type bearing structure of the water turbine is simple in structure and good in lubrication effect, a bearing bush cannot easily burn out, and the cylinder type bearing is large in bearing area, even in stress, stable in operation and quite convenient to manufacture, install and maintain.
Description
Technical field
The utility model relates to a kind of turbine shaft bearing structure, specially refers to a kind of water turbine oil immersion cartridge type bearing structure.
Background technique
Bearing arrangement is the important component part of unit, and its structural behaviour, workmanship and installation all directly have influence on operational reliability and the Security of unit.Prior art vertical shaft impact water turbine adopts two kinds of bearings usually: a kind of employing rotation oil tray formula cartridge type bearing, its oil circulation is to produce pressure by the oil tray rotation to enter bearing shell again, structure is comparatively complicated, mainly be useful for the relative small construction of radial dimension, and can not carry out the single nozzle operation basically; The another kind of piecemeal pad bearing structure that adopts, this structure is eight pieces watts, only be used for high rotating speed small capacity and some slow-speed of revolution units, the problem that exists is for the jumbo unit of high rotating speed, when unit load changes, when nozzle is switched, owing to be subjected to the effect of the eccentric jet of portion nozzle, an a certain watt local pressure occur and cross ambassador's turbine shaft and hold temperature and raise, make the unit can not stable operation.Obviously, the prior art bearing structure exists complex structure, can not carry out single nozzle operation, and the stressed ambassador of mistake of bearing shell turbine shaft holds temperature and raises, make unit can not stable operation etc. problem.
The model utility content
For solving the complex structure that the prior art bearing structure exists, can not carry out the single nozzle operation, the stressed ambassador of mistake of bearing shell turbine shaft holds temperature and raises, make unit can not stable operation etc. problem.The utility model proposes a kind of water turbine oil immersion cartridge type bearing structure.
A kind of water turbine oil immersion cartridge type bearing structure, its feature is being: divide the cartridge type bearing housing of half hitch structure to be contained in the main shaft axle neck outside, with the contacted axle neck of cartridge type bearing cylndrical surface radially be provided with one or more oil through, oil through one end is communicated to lower fuel tank, and the other end is communicated to the surface of contact of axle neck and cartridge type bearing; Be provided with one or more axle neck hole on the top of axle neck, an end in axle neck hole is communicated with top tank, and the other end is communicated with oil groove; In the inboard oil groove of axle neck, be provided with flinger ring; In top tank, be provided with cooler; Be provided with supporting part in cartridge type bearing bottom.
The useful technique effect of the utility model water turbine oil immersion cartridge type bearing structure is simple in structure, and high lubricating effect is difficult for tile kilning, and the loaded area of bearing is big, stressed evenly, stable, processing, installation and maintenance are very convenient.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model water turbine oil immersion cartridge type bearing structure;
Below in conjunction with the drawings and specific embodiments the utility model water turbine oil immersion cartridge type bearing structure is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the utility model water turbine oil immersion cartridge type bearing structure, and among the figure, 1 is main shaft, and 2 is the axle neck, and 3 is axle neck hole, 4 is oil groove, and 5 is oil through, and 6 is the cartridge type bearing, and 7 is lower fuel tank, 8 is supporting part, and 9 is cooler, and 10 is top tank, and 11 is flinger ring.As seen from the figure, a kind of water turbine oil immersion cartridge type bearing structure, the cartridge type bearing 6 of branch half hitch structure is sleeved on the main shaft axle and leads 2 outsides, with the contacted axle neck of cartridge type bearing 62 cylndrical surface radially be provided with one or more oil through 5, oil through 5 one ends are communicated to lower fuel tank 7, and the other end is communicated to the surface of contact of axle neck 2 and cartridge type bearing 6; Be provided with one or more axle neck hole 3 on the top of axle neck 2, an end in axle neck hole 3 is communicated with top tank 10, and the other end is communicated with oil groove 4; In the inboard oil groove 4 of axle neck 2, be provided with flinger ring 11; In top tank 10, be provided with cooler 9; Be provided with supporting part 8 in cartridge type bearing 6 bottoms.Lubricant oil in the top tank 10 of the utility model water turbine oil immersion cartridge type bearing structure enters lower fuel tank 7 backs and flows in the oil groove 4, main shaft 1 is lubricated, in main shaft 1 runs up process, axle neck 2 upper axis neck hole 3 makes top tank 10 equate with the air pressure of oil groove 4, the main shaft 1 of rotation makes lubricant oil flow to top tank 10 from axle neck hole 3 at a high speed, in 9 li coolings of cooler, flow to lower fuel tank 7 then, it is lubricated to continue to enter main shaft 1.Yi Bufen lubricant oil is lubricated by 5 pairs of axle necks 2 of oil through and cartridge type bearing 6 in addition, because the existence of oil groove 4, bearing shell has half in oil, has effectively reduced the temperature of cartridge type bearing 6, therefore is difficult for tile kilning.The utility model water turbine oil immersion cartridge type bearing structure is simple, and bearing shell has half in oil, and its lubrication effect is obvious especially.When changing, unit load can switch nozzle arbitrarily, stressed even because the loaded area of cartridge type bearing 6 is big, so stable.Adopt and divide the half hitch structure, easy processing, installation and maintenance are very convenient.
The useful technique effect of the utility model water turbine oil immersion cartridge type bearing structure is simple in structure, and high lubricating effect is difficult for tile kilning, and the loaded area of bearing is big, stressed evenly, stable, processing, installation and maintenance are very convenient.
