Technical field
This utility model relates to the input end structure of the input end structure of a kind of gear-box, especially power gearbox of wind power generator.
Background technology
Wind resource is green regenerative energy sources, inexhaustible.The most many countries, for the consideration of environmental conservation, are devoted to develop wind resource.The wind power equipment market of Europe and other developed country is the most fiery.The Chinese government the most also attaches great importance to the exploitation of wind-driven generator, and domestic localization of wind power equipment manufacturing also develops constantly.At present, based on 1.5MW～6MW serial fan, and having been achieved with mass production, 3MW～6MW series is the trend of blower fan future development.
Wind power generation gear case is parts the most crucial in complete machine, plays a part to transmit power in complete machine, and its quality good or not directly affects security performance and the economic performance of blower fan.High power gearbox typically uses two-stage planet+one-level parallel construction, and input generally uses Flange joint, and does not use shrink disk to connect.High power gearbox is to guarantee reliably transmitting of power, and input flange, planet carrier size and weight are the biggest.The input flange only connected and planet carrier weight just reach several tons, not only assemble relatively difficult, and start needs and overcome bigger inertia torque, and in start-up course, connecting bolt will be in the face of bigger shearing force toward contact.Practical experience proves, owing to input flange and planet carrier subject the moment of torsion from axis system, moment of flexure and part axial force, the working environment of input flange and planet carrier joint portion is the most severe, the fault of large gearbox occurs frequently in the power joint portion of line of input star, causes the use cost of the wind-driven generator of high-power type to remain high.Can guarantee that the connection of input flange and planet carrier is more reliable, it appears particularly important.
Utility model content
Utility model purpose is: subject the moment of torsion from axis system, moment of flexure and part axial force for high-power wind power generation gear-box input flange and planet carrier, the working environment of input flange and planet carrier joint portion is the most severe, the fault of large gearbox occurs frequently in the power joint portion of line of input star, cause the practical problem that the use cost of the wind-driven generator of high-power type is high, it is provided that the input end structure of a kind of power gearbox of wind power generator.
This utility model purpose is achieved in that the input end structure of a kind of power gearbox of wind power generator, including input flange, line of input carrier and connecting bolt, it is characterized in that, being provided with the friction shim of concentric between input flange and line of input carrier, concrete structure is:
A) the end face inner ring of line of input carrier is provided with equally distributed pin-and-hole, and outer ring is provided with equally distributed connecting screw hole, is provided with the pin of interference fit in pin-and-hole, and pin top is provided with inner bolt hole；
B) input flange is provided with the hole corresponding with pin-and-hole and connecting screw hole with friction shim；
C) being respectively provided with the bolt mated with connecting screw hole in line of input carrier and pin top inner bolt hole and a ring baffle, ring baffle is provided with the hole corresponding with pin in line of input carrier；
D) friction shim is between input flange and line of input carrier, input flange, friction shim and line of input carrier are sequentially connected with by the bolt mated with connecting screw hole in line of input carrier, meanwhile, it is connected fixing to ring baffle, input flange and pin with the bolt of pin top inner bolt hole coupling.
In this utility model: the pin of interference fit exposes to the actual height of line of input carrier end face and is not more than the actual (real) thickness sum of input flange corresponding to this connecting portion and friction shim.
In this utility model: the described bolt mated with connecting screw hole in line of input carrier is the high-strength hexagon socket head cap screw of 10.9S, described pin and the material of bolt mated with pin top inner bolt hole are 42CrMoA, and described friction shim surface is the friction shim containing diamond particle surface chemical plating nickel coating.
In this utility model: the connecting hole docked with input power is evenly distributed on the outmost turns of input flange.
The utility model has the advantage of: owing to being provided with friction shim between input flange and line of input carrier, the relative motion between input flange and line of input carrier can be stoped by the frictional force of friction shim.Owing to friction shim surface is containing diamond particle surface chemical plating nickel coating, after assembling, diamond particle will automatically insert in opposite face, form miniature interlocking, make contact surface be able to the most reliably and transmit bigger load.Bolt owing to mating with connecting screw hole in line of input carrier is the high-strength hexagon socket head cap screw of 10.9S, and the material of the bolt of described pin and pin top inner bolt hole coupling is 42CrMoA, guarantees connector reliable operation from material.Owing to the inner ring of the end face of line of input carrier is provided with equally distributed pin-and-hole, being provided with the pin of interference fit in pin-and-hole, pin can share or reduce starting torque and the shearing force adverse effect to connecting bolt.Input flange, friction shim and line of input carrier are sequentially connected with by the bolt owing to mating with connecting screw hole in line of input carrier, simultaneously, it is connected fixing to ring baffle, input flange and pin with the bolt of pin top inner bolt hole coupling, may insure that the pressure of the whole work surface of friction shim is basically identical, the frictional force also relative equilibrium therefore produced on work surface.This utility model compact conformation, technical measures are all linked with one another, it can be ensured that the input end structure of power gearbox of wind power generator is reliable, substantially increase the safety run under complex working condition.
