Abstract
The utility model provides a lubricating device for a big gear ring of megawatt wind power generation equipment, relating to a lubricating device for gears. The lubricating device for the big gear ring of the megawatt wind power generation equipment comprises oilgears, an electric grease pump and an oil passage distributor, wherein the electric grease pump is connected with the oil passage distributor through a main oil pipe, and the oil passage distributor is connected with the oilgears through branch oil pipes. The oilgear consists of a framework and an oil immersed layer inlaid in the framework, and oil passages communicated with the electric grease pump are formed in the oilgears. Matched with a control circuit, the lubricating device can achieve the purpose of controllably and intermittently supplying oil to an oil site, reduce the oil mass consumed by lubrication as much as possible on the premise of ensuring the lubricating effect, reduce oil stain and improve the utilization rate of lubricating oil, thus being applicable to the long-term maintenance-free running of the wind power generation equipment and having outstanding oil-saving effect.
Description
Technical field
The utility model relates to a kind of gear lubrication device, specifically a kind of megawatt level wind power generation equipment bull gear lubricating fitting.
Background technique
Send out in the driftage transmission and the transmission of change slurry of equipment at other wind-force of MW class, the mode that often adopts the driven by servomotor bull gear to carry out peripheral transmission is carried out.The transmission of this bull gear periphery simple and practical, cost is lower, and can satisfy the characteristics of the long-term low speed of wind power plant, heavy duty, intermitten service.Because the restriction of manufacturing and assembly technology, the precision of engagement was not high when bull gear and actuation gear cooperated, and had increased lubricated difficulty, and transmission is vital to described lubricating system reasonable in design for this bull gear periphery.
Should guarantee the realization of following characteristic about the design of this lubricating fitting:
1) lubricant grease evenly comprehensively adheres on the full Surface of action of flank profil, the blind spot that lubricates do not occur;
2) avoid the waste of lubricant oil secondary pollution and oil dripping, should satisfy the cleaning low power consuming operation under the long-term non-maintaining state of wind power plant.
3) high cost performance is saved and is produced and maintenance cost.
The model utility content
The purpose of this utility model is to provide a kind of megawatt level wind power generation equipment bull gear lubricating fitting, can guarantee good lubricating effect, in the hope of realizing the purpose of the long-term non-maintaining operation of wind power plant.
The technical scheme in the invention for solving the technical problem is: this kind megawatt level wind power generation equipment bull gear lubricating fitting, it is characterized in that, comprise oilgear, electronic grease pump, oil circuit distributor, described electronic grease pump is linked the oil circuit distributor by main oil pipe, and the oil circuit distributor connects some oilgears by the branch road oil pipe.
Described oilgear is made of the immersion oil layer of skeleton and embedding skeleton, and described oilgear contains the oil circuit that is communicated with electronic grease pump.
The facewidth of described oilgear is greater than the adjacent facewidth for the treatment of oilgear.
The beneficial effects of the utility model are: the utility model cooperates control circuit, can realize purpose to the lubricating point fuel feeding by controlled interruption, under the prerequisite that guarantees lubrication effect, reduce the lubrication oil amount as much as possible, reduce greasy dirt and improve the lubricant oil utilization ratio, be applicable to the long-term non-maintaining operation of wind power plant, oil-saving effect is outstanding.
Description of drawings
Fig. 1 is a schematic representation of the present utility model;
Fig. 2 is the topical application diagrammatic sketch;
Among the figure: 1 oilgear, 2 electronic grease pumps, 3 oil circuit distributors, 4 actuation gears, 5 gearwheels.
Embodiment
As shown in Figure 1 and Figure 2, this kind megawatt level wind power generation equipment bull gear lubricating fitting, be applied to the yaw gear of wind power generating set or become starch on the gear, this bull gear lubricating fitting is made of with the passive gearwheel 5 that is connected with the tower tube the actuation gear 4 that is connected with drive unit, belongs to the low-speed heave-load type and drives.
This lubricating fitting comprises oilgear 1, electronic grease pump 2, oil circuit distributor 3, and what their relative drive units were static is installed in the head cabin.Electronic grease pump 2 is linked oil circuit distributor 3 by main oil pipe, and oil circuit distributor 3 connects some oilgears 1 by the branch road oil pipe, realizes the purpose of an electronic grease pump while to a plurality of lubricating point fuel feeding.
Oilgear is made of the immersion oil layer of skeleton and embedding skeleton, and the immersion oil layer is preferentially selected porous for use and contained the good material of oiliness.Oilgear and actuation gear engagement, and the facewidth of oilgear is greater than the facewidth of actuation gear.Oilgear contains oil circuit, and described oil circuit is meant the pore type passage that is communicated with electronic grease pump in skeleton.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (3)
