Abstract
The utility model relates to a yaw speed-reducing machine for wind power generation. The machine is configured that a brake motor at the input end is connected with a cycloidal needle wheel decelerator with a wide deceleration ratio range while the output end adopts a two-graded planetary gear deceleration mechanism with strong wallop resistance. Smart advantage combination of the two is realized. So that the new yaw speed-reducing machine not only has simple structure and strong bearing ability, but also has the advantages of wide deceleration ratio range, smart speed changing and strong wallop resistance. By coupling the output gear wheel of the new yaw speed-reducing machine with the control gear of the wind power generator, control over the direction and angle of the wind power generator oar leaves can be realized. Therefore, steady operation and power generation of the wind power generator is ensured when changes in wind power and direction are complex and changeful.
Description
Technical field
The utility model belongs to the multi-stage speed-reducing machine, particularly relates to a kind of yawing reducer that is used for wind-power electricity generation.
Background technique
Wind-driven generator is the generator by the wind-drive rotation.Because the size and Orientation of wind-force is changeable, its most tangible characteristics are complicated and changeable, are the extremely strong energy of a kind of randomness, and the uncertain factor of the impact force that wind energy produces is more.Therefore,, be necessary for its configuration yawing reducer that anti-impact force is strong, reduction speed ratio is big,, keep the steady running of wind-driven generator in order to the angle and direction of regulation and control wind power generator oar blade in order to keep the stability of wind-driven generator.
At present, the domestic known yawing reducer that is used for wind-driven generator adopts following two kinds of structural types more, and a kind of is to adopt multi-stage planetary gear speed reducer structure.Planet-gear speed reducer has the strong advantage of anti-impact force, and still, the scope of its reduction speed ratio is little, in order to satisfy the big demand of reduction speed ratio, must adopt the multi-stage planetary gear gearing down, its complex structure, and volume is bigger, and the speed change inconvenience.Another kind is to adopt multistage cycloidal planetary gear speed reducer structure.Cycloidal planetary gear speed reducer has the big advantage of reduction speed ratio excursion, and still, its impact resistance is poor, can't reach the purpose that makes the wind-driven generator steady running.
Summary of the invention
The utility model provides a kind of cycloidal planetary gear speed reducer and two-stage planet reducing gear combination gearing down for solving the technical problem that exists in the known technology, is used for the yawing reducer of wind-power electricity generation.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of yawing reducer that is used for wind-power electricity generation, it is mainly by brake motor, cycloidal planetary gear speed reducer, the speed end sun gear, the speed end planetary gear speed reducing mechanism, low speed end sun gear, low speed end planetary gear speed reducing mechanism, output gear, spline, flat key, bearing, fastening piece such as pin and screw is formed, brake motor passes through screw, the flat key cycloidal planetary gear speed reducer that is connected, the output shaft of this cycloidal planetary gear speed reducer connects the speed end sun gear by spline, this speed end sun gear engagement speed end planetary gear speed reducing mechanism, the output shaft of this speed end planetary gear speed reducing mechanism connects low speed end sun gear by spline, its low speed end sun gear engagement low speed end planetary gear speed reducing mechanism, the output shaft of this low speed end planetary gear speed reducing mechanism connects output gear by spline.
Advantage and the good effect that the utlity model has are: for strong to wind-power electricity generation configuration anti-impact force, the yawing reducer that the reduction speed ratio scope is big, the utility model adopts cycloidal planetary gear speed reducer at input end, utilize its reduction speed ratio scope big, the speed change flexible characteristic, and adopt the planetary gear mechanisms for two stages transmission at output terminal, utilize the strong characteristics of its anti-impact force, realize the ingenious combination of both advantages, it is simple in structure that novel yawing reducer is not only had, the characteristics that bearing capacity is strong, but also it is big to have the reduction speed ratio scope, the advantage that anti-impact force is strong, this novel yawing reducer and wind-driven generator configuration are used, can realize the direction and the angle of wind power generator oar blade, make wind-driven generator under wind condition complicated and changeable, also can the steady running generating.
