Abstract
The invention provides an elastic support structure of a planet wheel. The elastic support structure of the planet wheel mainly comprises a bracket, the planet wheel, a bearing, a space ring and a planet pin, wherein the planet wheel is supported on a planet shaft by the support, at least one side end portion of the bearing is locked by a round nut, an adjusting space ring and a spring stop ring are arranged outside the round nut, the planetary shaft is sleeved on the planet pin and in interference link, and the bracket which is arranged on one side of the planet shaft is sleeved on the planet pin and in interference link. Bearings are two tapered roller bearings which are arranged side by side and are not provided with outer circles, and a round nut which has a radial positioning function is arranged on one end portion of the planet pin. The planet wheel is arranged between the bracket and the planet wheel, and a limit tapered ring which has an overload protection function on the planet pin is arranged under the condition of overload. The planet pin has elastic deformation and produces offset to effectively make up machining error of the planet wheel and a planet support, achieve the aim of good uniform load, and ensure synchronous meshing of multiple planet wheels.
Description
Technical field
What the present invention relates to is a kind of novel planet wheel elastic support structure, belongs to the power-transmitting unit technical field.
Background technique
In planetary mechanism, load balancing mechanism is the difficult point in design, and effect of load balancing mechanism has directly determined the product reliability of operation; Usually adopt sun gear or planet carrier to float in a planetary mechanism, because floating, sun gear or planet carrier structurally more easily process, and planet wheel is unsteady normally more unmanageable, as shown in Figure 1 be a kind of traditional planet wheel rigidity supporting structure, it is mainly by planet carrier 11, planet wheel 12, bearing 13, spacer ring 14, planet pin 15 compositions such as grade; Above-mentioned traditional planet wheel rigidity supporting structure has following shortcoming:
1, planet carrier due to the effect that is subjected to simultaneously moment of torsion and moment of flexure, easily produces and reverses and bending deflection, affects the accuracy of mesh of planet wheel;
2, planet wheel uses number that larger restriction is arranged, general maximum 4;
3, gear-box boundary dimension is large, and weight is large.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of can effectively solve planet wheel all carry a difficult problem, and the elastic support structure of the good planet wheel of effect of load balancing mechanism.
The objective of the invention is to complete by following technical solution, it is mainly by carriage, planet wheel, bearing, spacer ring, the planet pin forms, on planet axis, lock with round nut by a side end of bearing by bearings for described planet wheel, and round nut is equipped with one outward adjusts spacer ring and a check ring, described planet axis is nested with interference fit joint on the planet pin, and the carriage that is positioned at planet axis one side also is nested with interference fit joint on the planet pin.
Described bearing be two that be arranged side by side, not with the tapered roller bearing of outer ring, an end of described planet pin has been equipped with the round nut of axially locating effect; Being installed between described carriage and planet axis, a planet wheel planet pin is had the spacing conical ring of overload protective function under overload situations.
The present invention has following advantage:
1, be conducive to well all carry between planetary pinion;
2, the planet wheel number can be increased, 10 can be reached in the one-level planetary mechanism;
3, the planet wheel uniform tooth load is good;
4, can reduce planet wheel and planet carrier machining accuracy;
5, good buffer function improves the gear-box reliability;
6, can reduce gear-box boundary dimension and weight;

Fig. 2 is novel planetary wheel elastic support structure schematic diagram of the present invention.
Fig. 3 is elastic axis deformation pattern of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Fig. 2,3, the present invention is mainly by carriage, planet wheel, bearing, spacer ring, the planet pin forms, on planet axis 22, be equipped with one and adjust spacer ring 24 and a check ring 23 with round nut 25 lockings outside round nut 25 by at least one end of bearing by bearings for described planet wheel 27, described planet axis 22 is nested with interference fit joint on planet pin 21, and the carriage 31 that is positioned at planet axis one side also is nested with interference fit joint on planet pin 21.
Bearing of the present invention be two not with the tapered roller bearing 26 of outer ring, described planet pin 21 ends have been equipped with the round nut 30 of axially locating effect; One planet wheel 27 is installed between described carriage and planet axis 22 planet pin 21 is had the spacing conical ring 29 of overload protective function under overload situations.
Embodiment: as Fig. 2: planet wheel 27 is not supported on planet axis 22 with the tapered roller bearing 26 of outer ring through two; lock with round nut 25 the bearing end; an outer adjustment spacer ring 24 and the check ring 23 of being equipped with of round nut 25; together with round nut 25, bearing 26 there is double protection, has improved greatly the product operational reliability.Planet axis 22 and planet pin 21 interference fit joint, planet pin 21 and carriage 31 also interference fit joint.Planet pin 21 ends are equipped with round nut 30 and play the axially locating effect.As shown in Figure 3, when stressed, resiliently deformable occurs in planet pin 21 when planet wheel 27, and side-play amount is A.Spacing conical ring 29 has overload protective function to planet pin 21 at planet wheel 27 under overload situations.
Because planet wheel 27 and planet carrier 31 have inevitable machining error in course of working, cause the engagement magnitude of misalignment of a plurality of planet wheels when engagement, can not effectively guarantee a plurality of planet wheel synchromeshs.And thereby novel planetary as implied above wheel elastic support structure produces owing to there being planet pin 21 that resiliently deformable occurs the machining error that side-play amount has effectively made up planet wheel 27 and planet carrier 31, reaches and well all carries, and guarantees the synchromesh of a plurality of planet wheels.
