Abstract
The utility model discloses a planet carrier. Specifically a member (110) used by the planet carrier (100) is suitable for departing away from the planet carrier, and the member extends in a shaft direction. The member (110) strengthens a structure of the planet carrier (100), so torsion load is transmitted without generating a condition in which the planet carrier (100) is distorted.
Description
Technical field
The utility model relates to the planet carrier that uses in the epicyclic gear system, the planet carrier that relates more specifically to use in the wind turbine gearbox.
Background technique
In epicyclic gear system, the function of frame is that torque load is passed to planetary pinion from input shaft.Particularly in wind turbine application, frame also arrives the wind turbine rotor axle with the weight transmitting of gear-box.
These load can cause frame distortion, thereby cause following one or more:
The misalignment of-gear stage;
-owing to overcome the active scope that gear-box is installed, other load is applied to gear-box; And
-excessive vibration.
The rigidity that increases frame comprises with the method for avoiding these problems:
-thickening frame wall;
-change material into harder material; Perhaps
-interpolation timber.
Yet these methods have been introduced other problem.
For example, thicker wall has increased weight.
Use harder material to increase the cost of raw material, and possibly need complicated more casting process (for example, changing cast steel into) by SG iron.
Use timber can cause localized stress to promote, this can cause fatigue failure.This is at easy crisp material, for example problem especially in the foundry goods.Timber also causes more complicated casting.
The model utility content
The utlity model has the characteristic of the rigidity that is designed to increase frame.The utility model applies material in the outermost edge of free space.
According to a kind of mode of execution of the utility model, a kind of member that is used for planet carrier is provided, this member is suitable for extending vertically away from said planet carrier, and wherein, said member is cylindricality or truncated cone shape.This member is strengthened the structure of said planet carrier, so torsional load is transmitted under the situation that can not cause the planet carrier distortion.
Preferably, said member is connected to the frame shank comprises said member and said shank with formation assembly.Planet carrier can be connected to this assembly.The planet pin can be connected to this assembly through frame plate.Torsional load is delivered to the planet pin under the situation that does not cause the frame plate distortion.
Preferably, said member is connected to frame plate comprises said member and said frame plate with formation assembly.The assembly that comprises said member and said frame plate can be connected to the frame shank, therefore stops shank to twist with respect to frame plate.Shank can comprise the steel column between two frame plates.
Preferably, member is around the periphery location of said planet carrier.
Preferably, member is in the inwardly radial location of periphery of planet carrier.
According to the second aspect of the utility model, a kind of planet carrier that comprises the described member of aforementioned each claim is provided.
Description of drawings
To through example only the utility model be described with reference to accompanying drawing now, wherein:
Fig. 1 and Fig. 2 have shown a kind of sectional view of mode of execution of the planet carrier of the utility model, and Fig. 1 has shown planet pin and planetary position;
Fig. 3 A has shown a kind of schematic representation of mode of execution of the planet carrier of the utility model, and wherein, the member that extends from the planet carrier shank towards input shaft is a cylindricality; And
Fig. 3 B has shown a kind of schematic representation of mode of execution of the planet carrier of the utility model, and wherein, the member that extends from the planet carrier shank towards input shaft is taper.
Embodiment
Accompanying drawing has shown the planet carrier 100 that comprises frame plate 102, and frame plate has the hole or the groove 103 of the planet pin 104 that is used for planetary gear bearing 106.Two frame plates 102 combine through shank 108.The effect of planet carrier 100 is as far as possible equably torsional load to be delivered to planet pin 104 from input shaft (it engages planet carrier 100, shown in arrow 120 integral body).Although carrying out the effective means of this transmission is to adopt cylinder, planet carrier 100 must have the gap 105 that is used for planetary pinion 106.Gap 105 makes shear stress concentration at shank 108.
In known design, the function of frame plate 102 is to keep planet pin 104 and load is delivered to shank 108 from the planet carrier bearing.The function of shank 108 is frame plate 102 is combined.
The utility model provides the member 110 of 120 extensions from planet carrier shank 108 towards input shaft.This member be truncated cone shape (as Fig. 1,2 and 3B shown in) or the pipe of cylindricality (shown in Fig. 3 A).
The significant extension part of structure away from axially extended truncated cone shape of frame or cylindrical component 110 forms that extends to shank 108 couples together shank 108 securely.This has strengthened the structure of planet carrier 100 and has reduced shank 110 on each side with respect to the distortion of planet carrier 102.
Although to the maximum opposing of shearing load and bending (all be in vertical plane and reverse form) from 0 degree cone, i.e. cylindricality, what in this design, confirm to operate rigidity is the depth of material in the loaded planar.With reference to Fig. 3 A, it has shown cylindrical component 110, need dull and stereotyped 122 be accomplished to output shaft connection, and dull and stereotyped 122 can have high relatively flexible.With reference to Fig. 3 B, it has shown truncated cone shape member 110, and the end near output shaft 120 has littler diameter, this means that dull and stereotyped 122 have littler diameter, does not perhaps need.Therefore, although cylindricality itself possibly have more rigidity, because dull and stereotyped 122 is littler or do not need, truncated cone shape is arranged even more ideal.
The utility model also comprises the planet carrier that has like the described member of preamble.
