Abstract
The utility model discloses a slide yaw bearing device of a wind turbine, comprising yaw gear rings, side face bearings, slide liners and holders. The yaw gear rings are connected with a driving device; the side face bearings are more than one, each of which is respectively connected with the yaw gear rings in a way of matching, and the face of the each side face bearings which is contacted with the yaw gear ring is respective provided with a groove; the number of the slide liners is corresponding to that of the grooves on the side face bearings, and the slide liners are arranged in the grooves; and the holders are arranged on the main stander of an engine room and are connected with the side face bearings. The slide liners in the device are made from special materials and can form sliding friction with the yaw gear rings when the engine room yaws. The device provides desired damping torque and generates enough lubricant by lubricating without an individual braking system or additional grease lubricant to the yaw bearing. Therefore, the utility model has the effects of convenient operation, simple structure, compact structure, small maintenance workload, low maintenance cost and high cost performance.
Description
Technical field
The utility model is about technical field of wind power generation, more particularly, about a kind of, wind power generating set sliding type yaw axis bearing apparatus.
Background technique
In the wind-power electricity generation process, the wind wheel of wind power generating set should be in state down with the wind all the time.Therefore, need realize relatively rotating of cabin and pylon by the yaw system of being made up of drive unit and driftage bearing, the bearing enclose of driftage bearing is connected by bolt with pylon with the cabin of wind power generating set respectively.And, in the driftage process, producing excessive vibration and cause complete machine resonance for fear of wind power generating set, yaw system must have suitable damping torque when set yaw.Make that the wind wheel of under the effect of damping torque wind power generating set can accurate positioning, generate electricity and make full use of wind energy.
Existing yaw system includes rolling body type driftage bearing and driftage hydraulic brake.Because wind direction changes or when needing cable to untie the mooring rope, the driftage hydraulic brake provides required damping torque, deviation drive device by with rolling body type driftage bearing gear engagement, realize that the cabin is rotated and accurate location.But,, need regularly to this bearing supplemental lubrication fat, removing waste oil owing to adopted bearing and hydraulic system; Should make regular check on pipeline, oil level, oil pressure and the brake fluid thereof etc. of this hydraulic system.Its maintenance workload is big, maintenance cost is high, cost performance is on the low side.
The model utility content
In view of this, it is a kind of easy to operate, simple in structure, compact that main purpose of the present utility model is to provide, and maintenance workload is little, and maintenance cost is low, the wind power generating set sliding type yaw axis bearing apparatus that cost performance is high.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of wind power generating set sliding type yaw axis bearing apparatus, and it includes:
The driftage gear ring, described driftage gear ring is connected with drive unit;
The side bearing, described side bearing is more than one, described each side bearing is connected with described driftage gear ring respectively, described each side bearing with the contacted surface of contact of described driftage gear ring on offer groove respectively;
The quantity of the described groove on the sliding mats, the quantity of described sliding mats and described side bearing is corresponding, and described sliding mats is arranged in the described groove;
Be arranged on the retainer on the mainframe of cabin, described retainer is connected with described side bearing.
Described wind power generating set sliding type yaw axis bearing apparatus also includes the moment regulating device that is used to adjust damping, and described more than one moment regulating device is separately positioned on the bearing of corresponding described side.
The quantity of described side bearing is 5-10.
Beneficial effect after the employing technique scheme is: the sliding mats in the wind power generating set sliding type yaw axis bearing apparatus of the present utility model adopts special material to make, and can and going off course in cabin driftage process forms sliding friction between the gear ring.Required damping torque not only can be provided, can also pass through the enough oiling agents of friction-produced, need not independent braking system, also need not driftage bearing supplemental lubrication fat.Have easy to operately, simple in structure, compact, maintenance workload is little, and maintenance cost is low, the characteristics that cost performance is high.
