Description
Technical field
This utility model relates to a kind of planet circular system assembly, a kind of planet circular system assembly built by embedded gear ring.
Background technology
Epicyclic gearbox has compact conformation, ratio coverage is big, bearing capacity is high and transmission efficiency high, is widely used in every field, the wind-powered electricity generation industry developed rapidly the most in recent years.And the variable propeller gearbox vitals as wind-driven generator of going off course, properly functioning most important to wind-driven generator of its working condition.Yaw gearbox is used for regulating cabin and turns to, and variable propeller gearbox is for regulating the angle of blade, and both act on jointly, enable wind-driven generator to regulate cabin in real time according to the change of wind direction and wind-force and turn to and blade angle, in order to obtain appropriate wind-powered electricity generation wind-force rotating speed.
Owing to fan condition is the most changeable, and industry relevant criterion is insufficient, and different type of machines is gone off course the load of variable propeller gearbox by different clients and speed ratio is proposed different customization requirements.In the biggest load and ratio coverage, meet different customer requirements to realize driftage variable propeller gearbox, need to manufacture and design the planet circular system of the most different parameters.
In the structure of traditional driftage variable propeller gearbox, ring gear, in addition to the part filled as planetary gear pastern, also acts as the effect of casing, passes through bolt-connection between gear rings at different levels and casing.Different planet circular systems, then correspond to different ring gears and casing.Visible, traditional driftage becomes oar epicyclic gearbox and is difficulty with modularity, will necessarily be added significantly to buying, process and the cost such as management.
Yaw gearbox is similar with pitch gear box structure, is all multistage planet train parallel drive, and model is various and batch is relatively big, urgent and necessary to the modular requirement of parts.
Utility model content
The purpose of this utility model is, becomes oar epicyclic gearbox for traditional driftage and is difficulty with modularity, will necessarily be added significantly to buying, process and the practical problem of the cost such as management, it is provided that a kind of planet circular system assembly built by embedded gear ring.
The purpose of this utility model is achieved in that a kind of planet circular system assembly built by embedded gear ring, including casing and planet circular system, it is characterized in that: embedded gear ring planetary structure assembly includes gear for two stage planetary gear train, wherein: casing is that the integral cast that two-stage shares becomes casing, the ring gear of gear for two stage planetary gear train is during interference fit is arranged on casing respectively, and is positioned by corresponding hole gear；First order sun gear, planetary gear and planet carrier constitute first order planet circular system with first order ring gear, second level sun gear, planetary gear and planet carrier constitute second level planet circular system with second level ring gear, and the planet carrier in the first order is docked by spline with second level sun gear.
In this utility model: described first order sun gear, planetary gear and planet carrier forms the serial primary planet wheel assembly of different speed ratio from first order ring gear after mating, in primary planet wheel assembly, different first order planet carriers is consistent with the connection place Parameter of spline structure of second level sun gear.
In this utility model: described second level sun gear, planetary gear and planet carrier is and the series of secondary planetary wheeling assembly forming different speed ratio after second level ring gear coupling, in secondary planet wheel assembly, different second level sun gears is consistent with the connection place Parameter of spline structure of first order planet carrier.
The utility model has the advantage of: owing to becoming casing for two integral cast shared, the ring gear of gear for two stage planetary gear train during interference fit is arranged on casing respectively, can make gear for two stage planetary gear train organically combine together.First order sun gear, planetary gear and planet carrier can form the serial primary planet wheel assembly of different speed ratio based on first order ring gear, second level sun gear, planetary gear and planet carrier can form the series of secondary planetary wheeling assembly of different speed ratio based on second level ring gear, after gear for two stage planetary gear train assembles, the planet circular system assembly of some different drive ratios can be formed.
In series primary planet wheel assembly, different planet carriers is consistent with parameter portion, the spline connection place structure of second level sun wheel shaft, in series of secondary planetary wheeling assembly, different sun wheel shaft is consistent with the spline connection place argument structure of first order planet carrier, so may insure that two-stage combines docking coupling and standard is unified, achieve series and the change standard of a secondary planet train, buying is greatly lowered, processes and the cost such as management.
