Abstract
The utility model provides a novel planetary row. A planetary wheel shaft of the planetary row is connected with two arms of a planetary frame, the planetary frame and the planetary wheel shaft are axially positioned through adopting a baffle ring, the planetary wheel is arranged on the planetary wheel shaft and is engaged with a rolling pin bearing, a separation sleeve is arranged between the planetary wheel and the planetary wheel shaft, and a gasket is arranged between the planetary frame and the planetary wheel shaft. The planetary frame and the planetary wheel shaft adopt the baffle ring for realizing the axial positioning, the defect that the looseness can be easily caused when screws are adopted for positioning can be avoided, the positioning is reliable and safe, the planetary wheel shaft adopts a step shaft, the planetary frame can be prevented from damaging the surface of the planetary wheel shaft through scratching, the end surface of the planetary wheel is provided with a lubricating groove, an oil passage hole is drilled in an inner hole, the lubrication of a planetary wheel bearing can be favorably realized, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to a kind of novel planetary structure, specifically, is that a kind of planet carrier is the novel planetary row of arm structure.
Background technique
Wind power yawing, variable paddle speed reducer generally all adopt multistage planet transmission, the planet row of close output terminal, because rotating speed is low, transmitting torque is large, generally adopts the planet carrier of double-walled construction, and Gear Planet Transmission General Requirements compact structure, transmitting torque is large, and planet wheel bearing generally adopts needle bearing.Existing planet row planet carrier and planet wheel shaft generally adopt screw-driving to carry out axially locating, likely occur screw loosening, dropping situations, and cannot find in blower fan regular maintenance process in long-term operation process.Once toner screw, will cause planet wheel shaft outstanding, interfere with previous stage planet row, cause planet wheel bearing to damage, and screw falls between gear, may cause gear stuck, collapse the serious consequences such as tooth.
Summary of the invention
For the deficiency of above-mentioned situation, the utility model provides a kind of simple in structure, positioning security, novel planetary row structure reliably.
Novel planetary row of the present utility model, comprising: planet carrier 1, planet wheel shaft 5, planet wheel 2, spacer 3, pad 4, back-up ring 7, needle bearing 6, and wherein, 1 liang of arm of planet wheel shaft 5 and planet carrier is connected; Planet carrier and planet wheel shaft adopt back-up ring 7 to locate axially locating; Planet wheel 2 is arranged on planet wheel shaft, engages with needle bearing 6; Between planet wheel and planet wheel shaft, be provided with spacer 3; Between planet carrier and planet wheel shaft, be provided with pad 4.
Described planet wheel both ends of the surface are driven oil groove, on planet wheel endoporus, establish oil channel hole, and oil channel hole is set on planet wheel shaft.
Described planet wheel shaft adopts Step Shaft, is connected defeature face while preventing from being pressed into planet carrier and cause the needle bearing life-span to be fallen sharply with planet carrier two arm interference.
Planet carrier and planet wheel shaft adopt back-up ring to carry out axially locating, can prevent from adopting easily loosening defect of screw location, positioning security, reliable; Planet wheel shaft adopts Step Shaft, can prevent planet carrier scratch planet wheel shaft surface; Planet wheel end face is opened lubrication groove, bores oil channel hole on endoporus, is conducive to the lubricated of planet wheel bearing, improves bearing life.
Accompanying drawing explanation
Fig. 1 is this planet row structural representation.
Embodiment
As shown in Figure 1, novel planetary row of the present utility model, comprising: planet carrier 1, planet wheel shaft 5, planet wheel 2, spacer 3, pad 4, back-up ring 7, needle bearing 6, and wherein, 1 liang of arm interference of planet wheel shaft 5 and planet carrier is connected; Planet carrier and planet wheel shaft adopt back-up ring 7 to locate axially locating; Planet wheel 2 is arranged on planet wheel shaft, engages with needle bearing 6; Between planet wheel and planet wheel shaft, be provided with spacer 3; Between planet carrier and planet wheel shaft, be provided with pad 4.
Planet wheel shaft adopts Step Shaft, is connected defeature face while preventing from being pressed into planet carrier and cause the needle bearing life-span to be fallen sharply with planet carrier two arm interference; Planet wheel shaft axially adopts back-up ring to carry out axially locating, prevents that in planet row rotation process, planet wheel shaft is deviate from; On planet wheel shaft and planet wheel, oil channel hole is set, planet wheel both ends of the surface are driven oil groove, are beneficial to needle bearing lubricated, improve bearing life.
