Abstract
The invention discloses a yaw mechanical locking device of a wind turbine generator set. The mechanical locking device of the wind turbine generator set comprises a cabin chassis, a yaw bearing arranged on the lower side of the cabin chassis and a locking pin, wherein the yaw bearing is a bearing with teeth on the outer ring, the locking pin comprises a shaft body, axial teeth extended on the radial side of the shaft body are meshed with the teeth of the outer ring of the yaw bearing, the cabin chassis is provided with a locking pin hole, and the locking pin hole corresponds to the position of the teeth of the outer ring of the yaw bearing. When a yaw system is locked, the locking pin is inserted into the locking pin hole, and the axial teeth on the side of the locking pin are inserted between two neighboring teeth of the outer ring of the yaw bearing. The mechanical locking device of the wind turbine generator set increases the braking torque when a yaw reducer is replaced or under bad meteorological conditions, and increases safety factors of yaw braking.
Description
Technical field
The present invention relates to a kind of locking device of rotatable parts, relate in particular to a kind of mechanical locking for the wind generating set yaw system, belong to extraordinary power generating equipment technical field.
Background technique
Yaw system is one of wind power generator control system important component part, and its Main Function is according to the wind-driven generator operation conditions, its direction windward of Correctly adjust.The driftage of wind-driven generator is divided into the three basic working state: go off course, go off course counterclockwise, stop clockwise driftage.When going off course after rational position, need the locking yaw system, at present by yaw motor and the locking of water brake double shield, but when the yawing speed reducer that replacing goes wrong, need stop yaw motor, the braking moment of at this moment depending merely on water brake can not meet brake request completely; In addition, when blower fan meets with badness (typhoon weather), depend merely on above-mentioned double shield locking and exist potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of mechanical locking, the problem of braking moment deficiency when solve changing yawing speed reducer and under badness increases the safety coefficient of driftage braking.
The present invention is achieved by the following technical programs:
A kind of driftage mechanical locking of wind power generating set, comprise the cabin underframe, be arranged on driftage bearing, the stop pin of cabin underframe downside, described driftage bearing is that the outer ring shaft with gear is held, described stop pin comprises axis body, a described axis body radially side extends the axial tooth that meshes with yaw axis bearing outer-ring tooth, described cabin underframe is provided with lock pin holes, and described lock pin holes is corresponding with yaw axis bearing outer-ring tooth position; During the yaw system locking, stop pin inserts in lock pin holes, and the axial tooth of stop pin one side inserts between yaw axis bearing outer-ring two adjacent teeth.
The present invention also can further realize in the following manner:
The driftage mechanical locking of aforesaid wind power generating set, wherein said axis body cross section is circular shaft or polygon shaft.
The driftage mechanical locking of aforesaid wind power generating set, wherein said lock pin holes one side is provided with the side through hole that can allow axial tooth pass through; Described lock pin holes periphery also is provided with the counterbore that can hold the stop pin axial tooth, staggers in described counterbore and side through hole position.
The driftage mechanical locking of aforesaid wind power generating set, wherein said stop pin upper end is provided with a baffles; Described baffles upside is provided with handle.
The present invention sets up a locking device between wind power generating set original cabin underframe, driftage bearing, when yaw system need to lock, stop pin inserts in lock pin holes, the axial tooth of stop pin one side inserts between yaw axis bearing outer-ring two adjacent teeth, fixed the relative position of driftage bearing and cabin underframe, improved when changing yawing speed reducer or the braking moment under bad weather condition, increased the safety coefficient of driftage braking.Be provided with baffles in locking bearing pin upper end, this baffles is resisted against on the underframe of cabin, can prevent effectively that stop pin from coming off.After the taking-up stop pin unlocks, for nonvoluntary placement stop pin, prevent its loss, be provided with the counterbore that can hold the stop pin axial tooth in lock pin holes and the place of staggering, side through hole position, this counterbore is blind hole, stop pin is turned to the stop pin axial tooth drop in counterbore and get final product, in order to reuse.Baffles one end at stop pin also is provided with handle, the convenient stop pin that uses.
Advantage and disadvantage of the present invention will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiments only provide as an example with reference to accompanying drawing.
