Description
Technical field
The utility model relates to a kind of bearing device, specifically belongs to the resilient supporting unit in the mechanical transmission fields.
Background technique
The rotating speed of the major diameter low pressure fan that uses on the aviation birotary burbine Duct-Burning Turbofan and the rotating speed of minor diameter high pressure compressor differ greatly, the two is difficult to reach unified, therefore the designer's high pressure compressor and high-pressure turbine that will be operated in 11150rpm is combined into high pressure rotor, the low pressure fan and the low-pressure turbine that are operated in 6000-7000rpm are combined into low pressure rotor, being connected between the high pressure compressor of high pressure rotor and the high-pressure turbine adopted bending resistant section coefficient and the very big drum barrel axle form of Torsion Section coefficient, the slender axles form is adopted in being connected between the low pressure fan of low pressure rotor and the low-pressure turbine, then whole low pressure rotor is installed to the inside of high pressure rotor.This structural type rationally, compact, light and handy, but because high pressure rotor has strengthened the total length of low pressure rotor, make the slender axles of low pressure rotor become the gentle axle in the mechanics.Before low pressure rotor arrives specified 6000-7000rpm working speed, must pass through first critical speed or even second order critical speed of rotation, critical speed of rotation also claims dangerous rotating speed, resonance speed or destroys rotating speed that machinery is vibrated maximum, the stressing conditions complexity when critical speed of rotation.It is dangerous for fear of axle system resonance to take place, be necessary the 3rd supporting to be set in the neutral position of slender axles, and this 3rd supporting must be a yielding support, otherwise can cause the statically indeterminate problem on the mechanical structure, the feasible load that acts on the equipment bearing may reach ten times even 20 times of rating value.At present, the designer is mouse cage shape yielding support for the 3rd supporting of turbofan engine exploitation, described mouse cage shape yielding support is for being evenly distributed with one " mouse cage " of 24 spring levers along circumference, one end of " mouse cage " is supported on by centre bearing on the neutral position of low pressure rotor slender axles, and the other end is supported on the thin-walled drum barrel axle of high pressure rotor.The spring lever of milling moulding constitutes the yielding support of low pressure rotor with the form of overhang like this.In the motor running test, the partial spring lever when motor process critical speed of rotation in this mouse cage shape yielding support fractures.
In fact, all there are gentle axle, slender axles and longspan coupling resonance problem in the machinery in a lot of fields, as between the tail rotor of helicopter and the motor very long distance being arranged, its relative span is also long more a lot of than the gentle axle of aviation birotary burbine Duct-Burning Turbofan, also has the critical speed of rotation problem; Span between the propulsion device of naval vessels and ten thousand tons of wheels and the power cabin is bigger than the tail-rotor transmission shaft span of helicopter, also needs to solve the problem of length apart from the elastic coupling flexible coupling of transmitting torque; Machinery such as large-scale vertical stirrer, large-scale vertical cooling air tower, large-scale vertical cement kiln, large-scale vertical shredder, though working speed is not high, do not have the critical speed of rotation problem, but because its turning radius is very big, also elasticity of demand supports the weight of shunting the longspan axle; Wind-driven generator is in the high-altitude of liftoff 60-80m, for weight reduction and guarantee along reaching gravitational equilibrium on the wind-driven generator Short Position direction, the designer is arranged on generator the afterbody of whole wind power generator Short Position, weight with balance whole wind power generator Short Position head, this form has obviously strengthened the span of wind driven generator coupler, needs the compound elastic coupling flexible coupling of longspan; Planetary transmission at work, sun gear is among numerous planetary clampings, the danger that stress is concentrated can appear, for being avoided, sun gear is subjected to the destruction that stress is concentrated, be necessary to allow the internal gear that is in outer most edge be in quick condition to remove the overload of sun gear, way relatively more commonly used now is to set up a secondary inside and outside gear pair again in the outside of above-mentioned internal gear, this makes the weight of gear-shift transmission significantly increase, technology is complicated more, cost significantly raises, in order to escort, not only take above-mentioned way to wish that also the planetary pinion that cooperates with sun gear preferably also adopts certain floating installation simultaneously for sun gear.
Summary of the invention
The utility model purpose is: a kind of resilient supporting unit is provided, and this apparatus structure is simple, compact, and form is versatile and flexible, and it is dangerous not only can to avoid axle system that critical speed of rotation resonance takes place, and can also eliminate the stress concentration phenomenon of axle system.
