Abstract
The utility model discloses a yawing system of a wind power generator, which comprises a yawing gear, a yawing motor, a yawing bearing gear, a yawing gear shaft and a yawing motor output shaft, wherein the yawing gear is meshed with the yawing bearing gear; and the yawing system also comprises an electromagnetic clutch, a control system, an inductive wind wheel and a wind velocity measuring device, wherein the electromagnetic clutch is arranged between the yawing motor output shaft with a reduction gear box and the yawing gear shaft; the electromagnetic clutch is connected with the control system; the control system is connected with the inductive wind wheel; and the inductive wind wheel is provided with the wind velocity measuring device. The yawing system can control the connection and disconnection of the yawing motor and the yawing gear according to wind velocity, and runs safely.
Description
Technical field
The utility model relates to a kind of wind driven generator yaw system.
Background technique
The driftage driving gear of existing wind-driven generator and the main shaft the same axis in the gear-box, when braking device breaks down, the anti-driftage driving gear that drags of driftage driven gear, thereby towing astern motor rotation, because the driftage driven gear is very big with the velocity ratio of driftage driving gear, at this moment the driven gear of going off course becomes the driftage driving gear, the number of teeth of driftage driven gear is many, the number of teeth of driftage driving gear is few, the rotating speed of yaw motor under the drive of driftage driven gear be far above self rated speed, thereby easily yaw motor is caused damage.
The model utility content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of and can control yaw motor and yaw gear clutch, the wind driven generator yaw system of security of operation according to wind speed.
The technical solution of the utility model is: it comprises yaw gear, yaw motor, driftage Bearing gear, yaw gear axle, yaw motor output shaft, described yaw gear is meshed with the driftage Bearing gear, also be provided with magnetic clutch, control system, induction wind wheel and wind speed measuring device, be provided with magnetic clutch between the yaw motor output shaft of described band speed reducer and the yaw gear axle, magnetic clutch links to each other with control system, control system is connected with the induction wind wheel, and the induction wind wheel is provided with wind speed measuring device.
When the utility model surpassed setting value when wind speed, wind speed measuring device sent signal, and this signal is passed to control system, and control system makes the magnetic clutch dead electricity, and yaw motor and yaw gear are thrown off, thereby can protect yaw motor not to be damaged effectively.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, present embodiment comprises yaw gear 1, yaw motor 3, driftage Bearing gear 5, yaw gear axle 7, yaw motor output shaft 6, described yaw gear 1 is meshed with driftage Bearing gear 5, also be provided with magnetic clutch 2, control system 4, induction wind wheel 8 and wind speed measuring device 9, be provided with magnetic clutch 2 between the yaw motor output shaft 6 of described band speed reducer and the yaw gear axle 7, magnetic clutch 2 links to each other with control system 4, control system 4 is connected with induction wind wheel 8, and induction wind wheel 8 is provided with wind speed measuring device 9.
When the wind speed of responding to wind wheel 8 surpassed 25m/s in 10 minutes; perhaps when wind speed surpassed 35m/s in 3 seconds; wind speed measuring device 9 is passed to control system 4 with signal; control system 4 makes magnetic clutch 2 dead electricity; yaw motor 3 is thrown off with yaw gear 1, thereby can protect yaw motor 3 not to be damaged effectively.
Claims (1)
1. wind driven generator yaw system, comprise yaw gear, yaw motor, driftage Bearing gear, yaw gear axle, yaw motor output shaft, described yaw gear is meshed with the driftage Bearing gear, it is characterized in that, also be provided with magnetic clutch, control system, induction wind wheel and wind speed measuring device, be provided with magnetic clutch between the yaw motor output shaft of described band speed reducer and the yaw gear axle, magnetic clutch links to each other with control system, control system is connected with the induction wind wheel, and the induction wind wheel is provided with wind speed measuring device.
