Description
Technical field
The utility model relates to the planetary gear train in a kind of wind-driven generator wheel-box.
Background technique
Wind-power electricity generation is compared with traditional thermal power generation, has the free of contamination advantage of generating, compares with hydroelectric power, have that the capital construction cost is low, floor space is little, maintaining is advantage easily, and especially large-scale hydroelectric power plant, storage reservoir also cause certain potential safety hazard to the downstream easily.In wind-driven generator, gear-box is the critical component of wind-driven generator, and the wind-driven generator step-up gear of China's use at present mainly solves by import, is generally overall structure, and the dismounting difficulty in case break down, can only be changed assembly, causes waste.
In wind-driven generator wheel-box, usually adopt the mode of planetary gear train planet carrier input to carry out power transmission, because in the gear-box of some special constructions, can there be very big STRESS VARIATION in planet carrier part in the part operating mode, running to planetary gear train causes great potential safety hazard like this, traditional incorporate planet carrier structure can not satisfy this requirement, needs a kind of safer structure to satisfy this requirement.
The model utility content
The ultimate stress problem that the utility model exists under some operating modes at planet carrier in the planetary gear train, planetary gear train in a kind of novel wind-driven generator wheel-box is provided, it adopts the method for assembling planet carrier to satisfy STRESS VARIATION in the applying working condition, reduces the potential safety hazard that the planetary gear train running exists.
For realizing above technical purpose, the utility model will be taked following technological scheme:
Planetary gear train in a kind of wind-driven generator wheel-box, comprise ring gear, planet carrier, planet wheel shaft, planet wheel and sun wheel shaft, described planet carrier comprises planet carrier major axis, planet carrier minor axis and planet carrier disc, the two ends of planet carrier disc are connected with planet carrier minor axis interference fit with the planet carrier major axis respectively, and install respectively in the axis hole that planet carrier major axis and planet carrier minor axis correspondence are offered at the two ends of planet wheel shaft.
The interference fit junction surface that planet carrier disc and planet carrier major axis form is fastening by stripped nut, and this stripped nut links into an integrated entity planet carrier disc and planet carrier major axis by bolt and tab, and described stripped nut is located by straight pin.
The interference fit junction surface that planet carrier disc and planet carrier minor axis form is fastening by collar, and collar is socketed on the planet carrier disc, and collar is by the locating stud location and installation.
The planet carrier periphery is according to annular array mode four planet wheels that distributed.
According to above technological scheme, can realize following beneficial effect:
Planet carrier is made up of planet carrier major axis, planet carrier minor axis, planet carrier disc, be connected by interference between planet carrier disc and the planet carrier minor axis, undertaken fastening by locating stud and collar, be connected by interference between planet carrier disc and the planet carrier major axis, undertaken fastening by straight pin and stripped nut, stripped nut is undertaken locking by tab and bolt, the planet carrier that uses this structure has carried out fastening at the position that stress is concentrated, make the planet carrier bearing capacity be improved; In addition, the utility model according to annular array mode four planet wheels that distributed, makes the more uniform distribution of the load that acts on the planet carrier at the planet carrier periphery, has reduced local stress.
