Abstract
An automatic centering floatation structure with flexible inner gear rings comprises the inner gear rings, a combined gear ring, a floatation gear ring and planet wheels. The automatic centering floatation structure is characterized in that the planet wheels are provided with outer teeth; the number of the inner gear rings is two, and the inner gear rings are connected with the planet wheels through gears in a meshed mode; the inner gear rings are provided with outer teeth, the combined gear ring is provided with inner teeth, meanwhile, the combined gear ring is provided with outer teeth, and the inner gear rings and the combined gear ring are connected through a gear coupling; the floatation gear ring is provided with an inner gear and connected with the combined gear ring through a gear coupling. According to the automatic centering floatation structure, by means of increasing floatation of the positions of the inner gear rings and utilizing part flexibility deformation, load distribution between the planet wheels of a planetary gear box is even, the automatic centering floatation structure does not have radial support, allows radial and deflection displacement, can perform centering automatically during load imbalance and search for a balance position until loads of the planet wheels are distributed evenly.
Description
Technical field
The utility model relates to the planetary pinion load balancing mechanism, is specifically related to a kind of flexible ring gear self-alignment floating structure.
Background technique
Planetary Gear Transmission is that the axis of one or more gears is around the rotating gear transmission of the fixed axis of another gear.The main feature of Planetary Gear Transmission is that volume is little, and bearing capacity is large, stable working; But the Large-power High-Speed planetary gear transmission mechanism is more complicated, require accuracy of manufacturing high, main in structural design what consider is that the load shared of several planet wheels is even, therefore should adopt load balancing mechanism.
The model utility content
The purpose of this utility model is to provide a kind of flexible ring gear self centering floating structure, and this kind of floating structure mainly applied in the epicyclic gearbox load balancing mechanism, can realize the load uniform distribution between planet wheel in epicyclic gearbox.
The technological scheme that the utility model adopts is: a kind of flexible ring gear self-alignment floating structure, comprise ring gear, combination gear ring, float gear ring and planet wheel, and it is characterized in that: described planet wheel is provided with external tooth; Described ring gear is two, between described ring gear and described planet wheel, by gear, meshes and connects; Described ring gear is provided with external tooth, and described combination gear ring is provided with internal tooth, and simultaneously described combination gear ring is provided with external tooth, and described ring gear connects by gear coupling with combining between gear ring; Described unsteady gear ring is provided with internal gear, between described unsteady gear ring and described combination gear ring, by gear coupling, connects;
The above ring gear, combination gear ring and unsteady gear ring are flexible structure.
The beneficial effects of the utility model are: the utility model is by increasing floating and utilizing the distortion of part flexibility to make between each planet wheel of epicyclic gearbox load distribution even of ring gear place, this kind of floating structure do not add radial support, allowed radially to reach yaw displacement, but self-alignment when stand under load is unbalanced, find equilibrium position, until the load uniform distribution between each planet wheel; Be convenient to install simultaneously, by using gear coupling, can radially reach yaw displacement by effective compensation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of flexible ring gear self-alignment floating structure, comprise ring gear 1, combination gear ring 2, float gear ring and 3 planet wheels 4, and described planet wheel 4 is provided with external tooth; Described ring gear 1 is two, between described ring gear 1 and described planet wheel 4, by gear, meshes and connects; Described ring gear 1 is provided with external tooth, and described combination gear ring 2 is provided with internal tooth, and simultaneously described combination gear ring 2 is provided with external tooth, and described ring gear 1 connects by gear coupling with combining between gear ring 2; Described unsteady gear ring 3 is provided with internal gear, between described unsteady gear ring 3 and described combination gear ring 2, by gear coupling, connects;
The above ring gear 1, combination gear ring 2 and unsteady gear ring 3 are flexible structure.
When epicyclic gearbox moves, planet wheel 4 meshes moment of torsion and is delivered to ring gear 1, is delivered to respectively combination gear ring 2, unsteady gear ring 3 by two-layer gear coupling again, until moment of torsion output by gear.When the planet wheel load distribution is uneven, radially reach yaw displacement by the gear coupling compensation between ring gear 1 and combination gear ring 2, combination gear ring (2) and unsteady gear ring 3, self-alignment, reach the planet wheel load distribution even; When transmitting torque, can make the planet wheel load distribution even by flexible ring gear 1, combination gear ring 2 and the 3 stand under load distortion of unsteady gear ring simultaneously; Under the acting in conjunction of measure, reach the distributed uniform of load between each planet wheel so both ways.
