Together, and pipe axis runs through entire cabinet, the bearing that setting is interference fitted for inner ring and pipe axis at the rear box of gear-box, pipe
Axis is rotated as planet carrier rotates.High revolving speed output mechanism is provided at the rear box of wind turbine gearbox, high revolving speed exports machine
The work of structure driven generator, finds in actual use, and the part of the high revolving speed output mechanism in wind turbine gearbox compares mechanism
Part be more easier to damage；But cabinet can only be dismantled axially, it can not be radially unfolded；Simultaneously pipe axis through entire cabinet and with
The bearing and rear box of pipe axis are interference fitted, and needing to extract out on pipe axis could continue to dismantle cabinet, cause to dismantle cabinet expense in this way
When it is laborious.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide it is a kind of can on-site maintenance wind turbine gearbox, design knot
Structure is reasonable, reduces disassembly difficulty and improves the speed of disassembly.
Technical solution: it is described in the utility model can on-site maintenance wind turbine gearbox, cabinet and primary planet carrier, level-one
Planet carrier cooperates opposite case rotation by the level-one ring gear connecting with cabinet interference；It is provided on primary planet carrier for receiving
Receive and cable or wire and run through the pipe axis of cabinet, cabinet includes rear box, be nested with casing positioned at the pipe axis of rear box, casing with
Pipe axis is fixedly connected by pin shaft, and Casing bearing is provided on casing, and Casing bearing outer ring and rear box are interference fitted.
The axial retaining ring for the axial movement of limiting boot bearing is provided on casing.
Axial retaining ring uses in pairs, and is located at the axial ends of Casing bearing.
It is provided on rear box for the end cap one of sealing sleeve pipe and rear box and the end cap two being arranged on end cap one, end
Lid one and end cap two are all nested on casing, and are all fixed with rear box.
The outside framework oil seal for preventing oil seepage is provided in end cap two.
By using above-mentioned technical proposal, the high revolving speed mechanism in wind turbine gearbox include high speed grade gear wheel, jackshaft,
Jackshaft conical bearing, intergrade cylindrical bearing, high speed shaft cylindrical bearing, high speed shaft conical bearing and high speed level little gear shafting
Deng being removed between end cap one and end cap two first when finding high one or more part failure of revolving speed mechanism
Bolt successively dismantles end cap two, outside framework oil seal, shaft block ring and high speed level little gear shafting, then dismantles on casing and casing
Casing bearing and rear box.In this way it is not necessary that along axially withdrawn, the replacement of part in cabinet is can be completed in pipe axis.
The utility model has the advantages that the wind turbine gearbox replaces other parts in the case where not extracting pipe axis out, disassembly difficulty is reduced
Improve dismounting speed；With good leakproofness.
Detailed description of the invention
Fig. 1 is the wind turbine gearbox diagrammatic cross-section of the utility model；
Fig. 2 is enlarged drawing at A in Fig. 1.
Specific embodiment
As illustrated in fig. 1 and 2, it is a kind of can on-site maintenance wind turbine gearbox, cabinet 1 and primary planet carrier 2, primary planet carrier
2 engage the rotation of opposite case 1 with the level-one ring gear 3 that cabinet 1 is cooperatively connected by planetary gear；It is provided on primary planet carrier 2
For storing cable or wire and being provided on the pipe axis 4 of cabinet 1, pipe axis 4 for pipe axis 4 to be fixed on primary planet carrier
24 flange of pipe axis, 4 flange of pipe axis and pipe axis 4 are interference fitted.Cabinet 1 includes preceding cabinet 1 and rear box 5, positioned at rear box 5
Pipe axis 4 is nested with casing 6, and casing 6 is fixedly connected with pipe axis 4 by pin shaft, and Casing bearing 7, Casing bearing are provided on casing 6
7 outer rings and rear box 5 are interference fitted.The axial retaining ring 8 for limiting the axial movement of 4 bearing of pipe axis is provided on casing 6, it is axial
Retaining ring 8 uses in pairs, and is located at the axial ends of Casing bearing 7.
Easy to disassemble in order to facilitate the later period, rear box 5 is when handling the opening at casing 6, using being provided on rear box 5
For the end cap 1 of sealing sleeve pipe 6 and rear box 5 and the end cap 2 10 being arranged on end cap 1, end cap 1 and end cap 2 10
It is all nested on casing 6, and all fixed with rear box 5.Gap of the lubricating oil between end cap 2 10 and casing 6 is seeped in order to prevent
