Whole transmission system is arranged on High Altitude Platform frame, and requires that input, output shaft design for coaxial line in terms of appearance and size.
Motor, which need to be vertically installed on gear-box, carries out power input.Therefore, the body of this typical condition and use environment to gear-box
Product, weight have strict limitation.
The investigation of service condition is ground according to tower at home, tower roll flute roller box is typically parallel-axis type structure, its machinery
Structure diagram is as shown in Figure 1.The structure is specially by tertiary gear auxiliary driving, and preceding two-stage is the first parallel helical gear pair 16 and the
Two parallel helical gear pairs 17, output stage is by final stage sun wheel shaft 11, final stage planetary gear 12, final stage ring gear 13, final stage planet carrier
The final stage planetary gear train of 14 compositions, final stage planet carrier 14 is output shaft.The structural disadvantages are that gear-box weight is big, volume is big, right
Base support system and requirements of installation space are high.Also, due in the helical gear pair 17 parallel with second of first order helical gear pair 16
Away from consistent, this causes in terms of strength check the heart, and the first parallel helical gear pair Final 16 degree is rich, and utilization rate is not high, and second is flat
The intensity of row helical gear pair 17 deficiency, turn into the weak spot of whole gear-box, so as to influence the reliability of gear-box.These are all towers
Formula mill transmission system requires gear-box urgent problem to be solved.
Utility model content
The purpose of this utility model is, parallel axes slowing-down structure gear-box weight is used for current tower roll flute roller box
Greatly, a kind of the problem of volume is big, high to base support system and requirements of installation space, and reliability is not high, there is provided new tower mill
Use epicyclic gearbox.
The purpose of this utility model is achieved in that a kind of tower mill gear-box, including casing, it is characterised in that
Reducing gear by least by gear for two stage planetary gear train concatenate and group, the planetary gear train positioned at input are chopped-off head planetary gear train, chopped-off head
The sun wheel shaft of planetary gear train is docked with input shaft；Planetary gear train positioned at output end is final stage planetary gear train, final stage planetary gear
The planet carrier of system is output end；In the planetary gear train of concatenation, the sun wheel shaft of rear class planetary gear train is driven by prime planet carrier.
In the utility model, reducing gear is made up of chopped-off head, intergrade and final stage planetary gear train successively, wherein intergrade
The sun wheel shaft of planetary gear train is driven by chopped-off head planet carrier, the sun wheel shaft of final stage planetary gear train by intergrade planetary gear train row
Carrier drives.
In the utility model, described casing forms segmental structure after being split by the ring gear of planetary gear trains at different levels, respectively
The ring gear of planetary gear train is sealed with the corresponding casing section before and after it and docked.
In the utility model, tower mill is also equipped with electric machine support with the input of gear-box, and described electric machine support is consolidated
Dingan County is on the casing of input.
The utility model has the advantage of：Because reducing gear of the present utility model by gear for two stage planetary gear train by least being concatenated
And form, slow down bigger, and can realize that input shaft and output shaft are located at same axis so that vertical installation space
It is smaller.Because casing after the ring gear segmentation of planetary gear trains at different levels by forming segmental structure, the ring gear of each planetary gear train and position
Corresponding casing section sealing docking before and after it so that structure is compacter.Because the input of tower mill gear-box is also matched somebody with somebody
There is electric machine support, described electric machine support is fixedly mounted on the casing of input, can be provided for the motor of gear-box
One suitable installation foundation.Also, pass through comparing calculation, under equivalent specifications, the epicyclic gearbox weight that the utility model is related to
Amount lower than parallel-axis type structure 30% or so.
Brief description of the drawings
Fig. 1 is the structural representation of existing tower mill gear-box.
Fig. 2 is the structural representation of the utility model embodiment.
In figure：1st, electric machine support, 2, input shaft, 3, chopped-off head sun wheel shaft, 4, chopped-off head planetary gear, 5, chopped-off head ring gear, 6,
Intergrade planet pivoted frame, 7, intergrade sun wheel shaft；8th, intergrade planetary gear, 9, intergrade ring gear, 10, intergrade planet turns
Frame, 11, final stage sun wheel shaft, 12, final stage planetary gear, 13, final stage ring gear, 14, final stage planet carrier, 15 casings, 16, first is flat
Row helical gear pair, the 17, second parallel helical gear pair.
Embodiment
Fig. 2 is nonrestrictive to disclose concrete structure of the present utility model, the utility model is made below in conjunction with the accompanying drawings into
The description of one step.
The utility model includes casing, and reducing gear by gear for two stage planetary gear train by least being concatenated and group, positioned at input
Planetary gear train is chopped-off head planetary gear train, and the chopped-off head sun wheel shaft 3 of chopped-off head planetary gear train is docked with input shaft 2；Positioned at output end
Planetary gear train is final stage planetary gear train, and the final stage planet carrier 14 of final stage planetary gear train is output end；In the planetary gear train of concatenation,
The sun wheel shaft of rear class planetary gear train is driven by prime planet carrier.
From Figure 2 it can be seen that in embodiment of the present utility model, reducing gear is successively by chopped-off head, intergrade and final stage planet
Train forms, and in planetary gear trains at different levels, chopped-off head planetary gear 4 engages with chopped-off head sun wheel shaft 3 and chopped-off head ring gear 5 simultaneously, in
Intercaste planetary gear 8 engages with intergrade sun wheel shaft 7 and intergrade ring gear 9 simultaneously, final stage planetary gear 12 simultaneously with final stage too
Positive wheel shaft 11 and final stage ring gear 13 engage.Between each planetary gear train, the intergrade sun wheel shaft 7 of intergrade planetary gear train by
Chopped-off head planet carrier 6 drives, the final stage sun wheel shaft 11 of final stage planetary gear train by intergrade planetary gear train intergrade planet carrier 10
Driving.
In the present embodiment, described casing 15 after the ring gear segmentation of planetary gear trains at different levels by forming segmental structure, respectively
