Description
Technical field:
The utility model relates to a kind of Large-scale Wind Turbines sliding type driftage bearing, belongs to technical field of wind power generating equipment.
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, the yaw system that needs deviation drive device and driftage bearing to form is realized relatively rotating of cabin and pylon.Common driftage bearing mostly is four-point contact ball, and the Internal and external cycle of driftage bearing is connected by bolt with pylon with the cabin of wind power generating set respectively.And produce excessive vibration and cause complete machine resonance in the driftage process for fear of wind power generating set, yaw system must have suitable damping torque when set yaw, adopt the hydraulic type off-course brake more.Under the effect of damping torque, the wind wheel of wind power generating set can accurate positioning, makes full use of wind energy and generates electricity.Because wind direction changes or when needing cable to untie the mooring rope, the hydraulic type off-course brake provides required damping torque, driftage drives output pinion and driftage bearing gear engagement, realizes that the cabin is rotated and accurate location.But,, need to remove waste oil regularly to this bearing supplemental lubrication fat 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, the maintenance cost height, and cost performance is on the low side.
The model utility content:
The utility model purpose provides a kind of Large-scale Wind Turbines sliding type driftage bearing, the Large-scale Wind Turbines sliding type driftage bearing easy to operate, simple in structure, compact, that maintenance is little, maintenance cost is low, cost performance is high solves the problems referred to above that exist in the background technique.
The technical solution of the utility model is:
A kind of Large-scale Wind Turbines sliding type driftage bearing, comprise driftage gear ring, bearing assembly, slip lining, moment regulating device, frame and supporting component are provided with the moment regulating device with the slip lining coupling, slip lining cooperates with the driftage gear ring, reach the designing requirement of sliding friction, install by said modules, wind power generating set is in the driftage process, and the damping torque between slip lining and the driftage gear ring remains stable.According to actual conditions, can adjust the damping torque between slip lining and the driftage gear ring by adjusting the moment regulating device.
Slip lining comprises and radially slides liner plate and basal sliding liner plate.
Described driftage gear ring drives the output gear engagement with driftage; Described bearing assembly is 18, and each bearing assembly is connected with the driftage gear ring respectively, and the quantity of slip lining is corresponding with the quantity of bearing assembly; The moment regulating device is adjusted the damping torque radially slide liner plate and basal sliding liner plate respectively, and the moment regulating device at two positions respectively is 36, be installed on the corresponding bearing assembly respectively and frame on.
The beneficial effects of the utility model are: the slip lining in the wind power generating set sliding type driftage bearing of the present utility model can and be gone off course in cabin driftage process and is formed 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.
