Description
Technical field
The utility model relates to a kind of planet carrier, especially a kind of compact type planet carrier that is used for Yaw gearbox.
Background technique
The Yaw gearbox of wind-driven generator is one of vitals of wind-driven generator.Its effect is to be used for regulating engine rooms of wind power generators to turn to, and makes its variation that adapts to wind direction or wind-force, so that obtain suitable generating wind-force rotating speed.Because operating mode is more abominable, inconvenient maintenance adds that installing space is narrow and small, and Yaw gearbox all has strict requirement to reliability, weight, boundary dimension.
In planetary structure, the suffered load of the supporting on the planet wheel is maximum, and for slow speed turbine stage, the load of transmission is then bigger.For the rigidity that guarantees to support, the slow speed turbine stage planet carrier adopts double-walled construction more.Reduce the radial dimension of gear-box when increasing bearing capacity, needle bearing is completely adorned in the many employings of low speed planetary stage.In order to improve bearing capacity significantly, Yaw gearbox generally adopts the multistage planet structure.3 ~ 4 planet wheels of general even distribution on the planet carrier in every grade of planetary gear train, planet wheel carry all that number is general uses 3 or 4, but when load was bigger, it is longer more greatly that the gear-box size will become.
The model utility content
The purpose of the utility model is: the planet wheel supporting structure to existing Yaw gearbox is complicated, and radial length and weight are big, and the practical problem that space availability ratio is not high provides a kind of compact structure of new planet wheel.
The purpose of the utility model is achieved in that a kind of compact type planet carrier that is used for Yaw gearbox; Comprise: planet carrier, bearing pin and planet wheel is characterized in that: planet carrier is a both arms integral type planet carrier, evenly is provided with five bearing pin mounting holes on two arms of said planet carrier; Is furnished with a bearing pin in each bearing pin mounting hole; Five planet wheels are installed on the corresponding bearing pin through needle bearing respectively, and the end axle that goes out of said planet carrier is hollow shaft, is internal spline in the hollow shaft.
In the utility model: bearing pin one end face is butted on the bearing pin mounting hole limited step of an arm of planet carrier, and the other end is spacing in the bearing pin mounting hole of another arm of planet carrier through circlip for shaft.
In the utility model: the inner ring raceway of needle bearing is positioned on the bearing pin cylindrical, and the outer ring raceway of needle bearing is positioned at the endoporus hole wall of planet wheel, and the bearing two ends are located by the annular retaining ring thrust.
In the utility model: described bearing pin center is provided with oil leab, and the terminal point of oil leab is positioned at needle bearing.
The advantage of the utility model is: because planet carrier adopts both arms integral type planet carrier structure, processing and easy for installation is compared with the cantilever support of single armed planet carrier, and not only rigidity is big but also bearing capacity is high; Owing to used five planet wheels, all carry coefficient and be increased to 1.35 by 1.0, under the carrying condition equally, can greatly reduce the axial length overall of the thickness and the planet carrier of planet wheel; Because planet wheel has adopted needle bearing, especially the inner ring raceway of needle bearing is positioned on the bearing pin cylindrical, and the outer ring raceway of needle bearing is positioned at the endoporus hole wall of planet wheel; The bearing two ends are located by the annular retaining ring thrust; Structure is very compact, because bearing pin one end face is butted on the bearing pin mounting hole limited step of an arm of planet carrier, the other end is spacing in the bearing pin mounting hole of another arm of planet carrier through circlip for shaft; Installing and locating is convenient; Because the bearing pin center is provided with oil leab, the terminal point of oil leab is positioned at needle bearing, can prolong the working life of planet carrier.
