Description
Technical field
The utility model relates to wind-driven generator assembly, is specifically related to a kind of mainframe controlled based on comprehensive angle.
Background technique
Main frame of wind generating set is the significant components of wind-driven generator, and it is arranged on tower cylinder usually, mainframe is provided with the wind wheel for collecting wind energy.Existing main frame of wind generating set can divide two classes substantially: 1) mainframe and bearing support split-type structural (as Fig. 1), and wind wheel is being produced load to (substantially along path shown in dotted line) on the path that tower cylinder transmits by this kind of structure, and a-quadrant easily produces stress and concentrates; 2) large bearing structure (as Fig. 2 and 3), this structure can complete preferably by the transmission of load, but existing large bearing structure mainframe, in order to solve the installing/dismounting problem of gear-box, by the import and export (referring to be arranged on the hole on mainframe top bevel) of gear-box herein along Directional Extension shown in arrow, though this solves an assembling difficult problem, the stress of this feature and adjacent area joint is also caused to concentrate.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of mainframe controlled based on comprehensive angle, makes it that disengage gear case can not only be made convenient, and stress can be avoided to concentrate, ensure working life.
The utility model is solved the problem by following technological means: a kind of mainframe controlled based on comprehensive angle, comprise support body, described support body front end is provided with the main bearing fitting seat for fixed main shaft bearing, angle theta between described main bearing fitting seat and described support body bottom surface is 4 °-6 °, described support body bottom surface is provided with driftage drive installation seat, gear case elastic support fitting seat is provided with in described support body, support body rear end is provided with extension part, be connected by inclined-plane between described extension part with support body end face, angle α between described inclined-plane and support body bottom surface is 36 °-40 °, described inclined-plane is provided with a hole, angle β between described extension part tail end and vertical surface is 21 °-25 °.
Further, described α is 38 °.
Further, described β is 23 °.
The beneficial effects of the utility model: the mainframe controlled based on comprehensive angle of the present utility model, comprise support body, described support body front end is provided with the main bearing fitting seat for fixed main shaft bearing, angle theta between described main bearing fitting seat and described support body bottom surface is 4 °-6 °, described support body bottom surface is provided with driftage drive installation seat, gear case elastic support fitting seat is provided with in described support body, support body rear end is provided with extension part, be connected by inclined-plane between described extension part with support body end face, angle α between described inclined-plane and support body bottom surface is 36 °-40 °, described inclined-plane is provided with a hole, angle β between described extension part tail end and vertical surface is 21 °-25 °.The master bracket of this structure, in using process, not only disengage gear case is convenient, and it is concentrated to avoid stress, ensure that working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the mainframe schematic diagram of existing mainframe and bearing support split-type structural;
Fig. 2 is that existing large bearing structure formula mainframe just sees schematic diagram;
Fig. 3 is that existing large bearing structure formula mainframe is bowed and seen schematic diagram;
Fig. 4 is the structural representation of the application;
Fig. 5 is the relation schematic diagram of θ, α and β.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail, as illustrated in figures 4-5: a kind of mainframe controlled based on comprehensive angle, comprise support body 1, described support body front end is provided with the main bearing fitting seat 2 for fixed main shaft bearing, angle theta between described main bearing fitting seat and described support body bottom surface is 4 °-6 °, θ is 5 ° herein, described support body bottom surface is provided with driftage drive installation seat 3, gear case elastic support fitting seat 4 is provided with in described support body, support body rear end is provided with extension part 5, be connected by inclined-plane 6 between described extension part with support body end face, angle α between described inclined-plane and support body bottom surface is 36 °-40 °, α is 38 ° herein, described inclined-plane is provided with a hole 7, angle β between described extension part tail end and vertical surface is 21 °-25 °, β is 23 ° herein.This structure based on comprehensive angle control mainframe, on the one hand, α is 36 °-40 °, can make wind loads smooth-going be delivered to tower cylinder, avoid support body stress concentration, can avoid again because α is excessive, support body weight strengthen and cause stress raisers; On the other hand, at the afterbody of support body, extension part is set, and make the angle β between extension part tail end and vertical surface be 21 °-25 °, the hole offered so just can be made can to meet the turnover of gear-box, can guarantee that again the wheel hub in hole is approximately a circle, and the shortcoming that support body is overweight because β is excessive can be avoided, support body upper stress can be well avoided to concentrate, well can bear the torque around each foundation fiducial axis, the torque (i.e. My torque) of especially bearing around y-axis ensure that the working life of mainframe simultaneously.
In sum, the master bracket controlled based on comprehensive angle of this structure, in using process, not only disengage gear case is convenient, and it is concentrated to avoid stress, ensure that working life.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
