Description
Technical field
The present invention relates to wind power generation field, in particular to a kind of wind power generating set and gear-box.
Background technique
Wind power generating set includes wind wheel, gear-box, generator and mainframe.The revolving speed or torque of wind wheel input pass through tooth
Revolving speed needed for roller box is converted to generator or torque, gear-box is hung by suspender to be raised to after enough height with suspender along gear-box
It is axially moved, is inserted into gear-box rear box in the gear-box mounting hole of mainframe.It is additionally provided on mainframe for safeguarding people
Member enters the ladder mouth of mainframe, and ladder mouth is located near gear-box rear box.Lubricating oil is added in gear case body, makes one
Operative gear is in lubricating oil liquid level hereinafter, lubricating oil is transmitted on each gear by contact of the gear with gear, to tooth
Wheel is cooled down and is lubricated.In order to lubricate internal each gear adequately, forced feed lubrication is additionally used.It is strong in order to make
The oil pump of system lubrication does not cause to be emptied, and the liquid level of lubricating oil cannot be too low, and the churning loss for resulting in gear in this way increases, lubrication
The problems such as oil temperature is high.
The prior art is made that improvement to gear box structure, improves 1: doing one along cabinet axis in gear-box rear box lower part
Protrusion, for accommodating the lubricating oil of a part, in the case which can keep lubricating oil liquid level not rise to a certain extent
Increase lubricating oil total amount in gear case body.But the protrusion increases the axial length of gear-box, reduces cabin ladder mouth
Surrounding space influences the maintenance of generating set.
It improves 2: in gear-box rear box bottom opening, one auxiliary fuel tank being set in rear box bottom, is connected with rubber flange
Auxiliary fuel tank is connect, the structure is less in the intracorporal lubricating oil of case, and churning loss is small, oil sump temperature is low.But there are two lack for the gear-box
Point: first is that auxiliary fuel tank and gear-box needs separate when lifting, increase working hour and assembly difficulty；Second is that auxiliary fuel tank and rubber flange
There is permeability risk, since the space of gear-box bottom is limited, once there is oil leakage problem, secondary oil can not be replaced in fan engine room
Case, oil leakage problem can not be eradicated.
Summary of the invention
The object of the present invention is to provide a kind of wind power generating sets, are being pacified with solving the gear-box of existing wind power generating set
The problem and auxiliary fuel tank of the problem of lifting, the small caused later maintenance difficulty in cabin ladder mouth space are difficult to when being attached in mainframe
It is easy oil leakage problem.The object of the invention is also to provide gear-boxes used in a kind of above-mentioned wind power generating set, to solve
Existing wind-driven generator group wheel box be difficult to when being installed in mainframe the problem of lifting, cabin ladder mouth space it is small caused by
The problem and auxiliary fuel tank of later maintenance difficulty are easy the problem of permeability.
To achieve the above object, the technical solution of wind-power electricity generation group of the invention are as follows: wind power generating set, including wind wheel,
Gear-box, generator and mainframe, gear-box include preceding cabinet, rear box and the movement parts in preceding cabinet, rear box, preceding
Cabinet is connected with rear box using connecting flange, has cavity and slow-speed shaft and bearing components in cavity in preceding cabinet；
There are cavity and high speed shaft, gear and bearing components in cavity in rear box；Wind wheel is connected with gear-box slow-speed shaft, hair
Motor is connected with high speed shaft of gearbox, and the bottom of box has the sink structures as fuel tank before the gear-box.
Wind power generating set of the invention the utility model has the advantages that in terms of existing technologies, present invention decreases gear-boxes
The size of rear box makes gear-box convenient for lifting and installation；And the cabin ladder mouth space by gear-box rear box is increased, just
In later maintenance.It is low in cabinet before gear-box because in common wind power generating set invention increases preceding cabinet radial dimension
Fast axis need to only be connected with wind wheel, generally be not provided with other parts around preceding cabinet, in the case where the preceding bottom of box is equipped with as fuel tank
Sink structure takes full advantage of cabinet surrounding space before gear-box, influences on the installation of wind power generating set and maintenance little.
Further, the sink structures of cabinet manufacture difficulty before the gear-box in order to solve the problems, such as wind power generating set,
It is split type structure, releasable connection between the two between the fuel tank and the other parts of gear-box.
Further, the oil leakage problem that fuel tank position occurs in order to prevent guarantees connective stability, the fuel tank and gear
Pass through flange releasable connection between the other parts of case.
Further, for the churning loss of gear, transmission efficiency is improved, gear-box rear box is integrated shell or along axis
To multistage shell is divided into, the speed end bottom of integrated shell or speed end housing bottom are along tangential removal.
Gear-box of the invention use following technical scheme: gear-box, including preceding cabinet, rear box and be located at preceding cabinet,
Movement parts in rear box, preceding cabinet and rear box are connected using connecting flange, are had cavity in preceding cabinet and are located in cavity
Slow-speed shaft and bearing components, there is in rear box cavity and high speed shaft, gear and bearing components in cavity, the tooth
The bottom of box has the sink structures as fuel tank before roller box.
Gear-box of the invention the utility model has the advantages that in terms of existing technologies, present invention decreases gear-box rear box
Size, make gear-box convenient for lifting and installation；And the cabin ladder mouth space by gear-box rear box is increased, it is convenient for the later period
Maintenance.Invention increases preceding cabinet radial dimension, because in common wind power generating set, slow-speed shaft is only in cabinet before gear-box
It need to be connected with wind wheel, generally be not provided with other parts around preceding cabinet, be equipped with the sink structures as fuel tank in the preceding bottom of box
Cabinet surrounding space before gear-box is taken full advantage of, the installation of wind power generating set and maintenance are influenced little.
Further, in order to which the sink structures manufacture for solving the problems, such as cabinet before gear-box is difficult, the fuel tank and gear
It is split type structure, releasable connection between the two between the other parts of case.
Further, the oil leakage problem that fuel tank position occurs in order to prevent guarantees connective stability, the fuel tank and gear
Pass through flange releasable connection between the other parts of case.
Further, for the churning loss of gear, transmission efficiency is improved, gear-box rear box is integrated shell or along axis
To multistage shell is divided into, the speed end bottom of integrated shell or speed end housing bottom are along tangential removal.
