Abstract
The utility model discloses a wind-electric combined planetary frame, an inner planetary frame with a connecting plate is jacketed to an outer planetary frame with an orifice plate, a cylindrical pin for transmitting torque with a circular interface whose axial size adapted to the cylindrical pin is arranged in the middle place of the connecting plate of the inner planetary frame, the inner and outer planetary frames are secured with the cylindrical pins and fixed with bolts, and the other parts and the inner planetary frame are suspended after assembly. For the torque action on the middle position of the connecting plate of the planetary frame, so whether the orifice plate of the planetary frame is deformed and/or small or large, the planet axis will not deviate from the central wheel axis but in parallel. The utility model has the advantages of minimum eccentric load in the tooth length direction of the planetary wheel and the inner gear, the eccentric loads of the central wheel and the planetary wheel are reduced, thereby ensuring same stress sizes and/or directions, greatly prolonging the service life of the planetary bearing, keeping the transmission reliability of the planetary gears, and especially used in the places with variable torque inputted the as wind power generation, hydraulic generation and others.
Description
Technical field
The utility model relates to the improvement of the epicyclic gearbox planet carrier that a kind of speedup of generating electricity uses, a kind of specifically assembly planetary carrier, and the planetary pinion speedup that is particularly suitable between wind-driven generator paddle sheet and the generator is used.
Background technique
Planetary shaft axis is directly proportional with the transmission power or the moment of torsion of gear-box with the size of the angle excursion of the shaft axis generation of central gear in general wind-powered electricity generation epicyclic gearbox, when becoming power or becoming the moment of torsion transferring power, cause Basis of Gear Deviation Load and two dish planetary bearing unbalance loadings, have a strong impact on the reliability of the bearing life of calculating.Especially the megawatt-level wind epicyclic gearbox belongs to the transmission of typical low-speed heave-load change torque power, using the middle gear correction of the flank shape in engineering designs by a certain constant-torque (operation point), but in different wind energy turbine set, this constant moment of torsion is different, this has just caused the unbalance loading of Basis of Gear Deviation Load and two dish planetary bearings, thereby causes the inefficacy in advance of bearing.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned defective of the prior art, designs a kind of rational in infrastructure, assembly planetary carrier that can effectively overcome above-mentioned drawback.
The purpose of this utility model is such realization: the planetary inner frames and the planetary outer frames socket with orifice plate that promptly have connecting plate, the straight pin of transmitting torque is housed in the neutral position of planetary inner frames connecting plate and has axial dimension and annular mating face that the straight pin size is suitable, inner and outer planetary frames connects, uses bolton with straight pin, and other position and planetary inner frames that the back planetary outer frames is installed are unsettled.
Three planet wheels are housed on the described planet carrier at least, and the connecting plate on the planet carrier is identical with the planet wheel number with straight pin, and two dish or polydisc bearings are housed on its planet axis, on the outer ring of bearing planetary pinion is housed.
Orifice plate symmetric arrangement on the described planetary outer frames.
The utlity model has following advantage: this assembly planetary carrier structure, because torsional interaction is in the neutral position of planet carrier connecting plate, so no matter whether planet carrier orifice plate and connecting plate are out of shape or are out of shape size, can not make planet axis and central gear (also claiming sun gear or internal gear) axis produce deflection, all will remain parallel.Guaranteed that planet wheel and the internal gear unbalance loading on the tooth length direction is minimum, again sun gear is reversed axial modification, can reduce sun gear and planet wheel unbalance loading effectively, the stressed size, the direction that guarantee two dish planetary bearings are basic identical, improved the working life of planetary bearing greatly, guarantee the reliability of planetary pinion transmission, thereby reached the purpose of this utility model.

Embodiment
With reference to Fig. 1, Fig. 2, with three planet wheels is example, the utility model is made up of four assemblies, the planetary inner frames (1) and planetary outer frames (2) socket that promptly have connecting plate with orifice plate, the neutral position of planetary inner frames (1) connecting plate is equipped with the straight pin (3) of transmitting torque and is had axial dimension and annular mating face (9) that straight pin (3) size is suitable, inner and outer planetary frames (1,2) locatees, uses bolt (4) fastening with straight pin (3), and other position and the planetary inner frames (1) unsettled [seeing unsettled seam (5)] of back planetary outer frames (2) is installed.On the orifice plate of planetary outer frames (2), be provided with the hole (7) of fixed planet shafts, three planet wheels are housed on the planet carrier at least, connecting plate on the planet carrier is identical with the planet wheel number with straight pin (3), and two dish or polydisc bearings are housed on its planet axis, on the outer ring of bearing planetary pinion is housed.Orifice plate symmetric arrangement on the planetary outer frames (2).Diagram only is a kind of form of combined planetary frame, and the quantity of the connecting plate on planet wheel and the assembly planetary carrier, according to the size of transmitting torque can be four, five, six and symmetric arrangement.
On wind-powered electricity generation planet speedup box, moment of torsion is imported from planetary inner frames (1) left end, by straight pin (3) moment of torsion is passed to planetary outer frames (2), by the orifice plate of the last symmetric arrangement of planetary outer frames (2) moment of torsion is passed to planet axis again, two dish or polydisc bearings are housed on the planet axis, on the outer ring of bearing, planetary pinion are housed.This fabricated structure, no matter the torque of input, planetary inner frames (1) connecting plate produces great torsional deflection, is contained in the shaft axis (8) of planetary outer frames (2) upper planet axle, all incites somebody to action all the time and central gear axis (6) keeping parallelism.Thereby reduced the unbalance loading of gear pair and the distribution inequality of planet wheel middle (center) bearing load greatly, improved the reliability of bearing and gear.So this structure is particularly suitable for becoming the occasion of moment of torsion input, as wind-power electricity generation, hydroelectric power etc.
