Description
Technical field
This utility model belongs to mechanical transmission fields, particularly relates to a kind of floating solar wheel axial positioning structure.
Background technology
In the epicyclic gearboxes such as wind turbine gearbox, adopting spline to be in transmission connection between the sun gear of previous stage and the gear wheel of rear stage or planet carrier, this attachment structure bearing capacity is high, and floating effect is good, therefore obtains relatively broad application. But, sun wheel shaft hinders the further genralrlization of this structure to orientation problem always, due to sun gear sustained oscillation in running, often lead to sun gear axial positioning structure and subject the shock loading of frequently change, and traditional sun gear axial positioning structure is all the combination that pressing plate adds bolt, this axial fixing structure poor reliability, often lost efficacy, and even caused the damage of whole gear-box.
Summary of the invention
This utility model is for overcoming the problems referred to above, it is provided that a kind of can guarantee that floating solar wheel effectively engage with three planetary gears while, it is ensured that its thrust bearing is constantly subjected to pretightning force, it is possible to sun gear is axially positioned.
A kind of floating solar wheel axial positioning structure, including sun gear, planetary gear, inner spline gear hub, spline, rebound, back casing, spacer ring, biserial thrust roller bearing and adjustment ring, the sun gear of helical teeth engages with planetary gear, spline engages with inner spline gear hub, inner spline gear hub has the bulge-structure that can limit sun gear play to the left, inner spline gear hub is fixed on rebound and back casing by inner spline gear fore bearing and spline tooth rear bearing, it is connected with spacer ring by a straight pin on the right side of spline, equipped with compression spring in spacer ring, compression spring heads on outer ring on the left of biserial thrust roller bearing, on the right side of biserial thrust roller bearing, outer ring leans against in adjustment ring, inner spline gear hub is bolted oil pump gear wheel, oil pump gear wheel is connected with adjustment ring by bolt, biserial thrust roller bearing inner ring is axially positioned by the step of hollow pipe and sleeve and locking nut.
Described planetary gear has three, circumference 120 �� distribution, engages with sun gear.
Oil pump gear wheel end cap is stamped in described oil pump gear wheel front end.
The beneficial effects of the utility model: this utility model design compressed spring type location structure, floating performance without limitation on floating solar wheel, ensure that floating solar wheel is planetary with three effective to engage, simultaneously the moment can provide pretightning force for thrust bearing again, it is ensured that sun wheel shaft is to the reliability of location.
