At present, the driftage bearing in the yaw system of wind power generating set mainly contains two kinds of type of belt drive, and a kind of is the type of belt drive that adopts rolling bearing, and another kind is the type of belt drive that adopts slide construction.The yaw system main feature of slip form is simple in structure, good reliability.But the yaw system of this type of belt drive requires the gap between side friction plate and the driftage gear ring inboard is accurately adjusted in assembling process, makes it within reasonable range.
Existing adjusting play method is: at first the side friction sheet is fixed on the bearing of side; Mainframe is lifted on above the driftage gear ring and with driftage gear ring and side bearing and is connected; With clearance gauge the gap between side friction plate and the driftage gear ring inboard is measured then; When in its scope that is not requiring, need the connecting bolt between side bearing and the mainframe be unclamped fine setting side bearing; Make gap between side friction sheet and the driftage gear ring inboard within the scope that requires, tighten connecting bolt then.Use the same method, each side bearing is adjusted.This method is not only time-consuming, and can not guarantee the axiality of cabin at each side bearing of when driftage, thereby makes each side skidding wearing and tearing uneven, causes the cabin play, causes the phenomenons such as fatigue wear, broken teeth of yaw drive and driftage gear ring tooth.
The utility model content
The utility model provides a kind of wind generating set yaw system assembling servicing unit, in order to reduce construction cost, reduces the wearing and tearing and the driftage noise of side friction sheet, improves the meshing efficiency of tooth.
For achieving the above object, the utility model provides a kind of wind generating set yaw system assembling servicing unit, and it comprises: frock carriage, tool locating ring, alignment pin and bolt, wherein
The frock carriage is connected between the side bearing and driftage gear ring of yaw system through bolt;
Alignment pin is installed on the bearing of side, and the tool locating ring is connected with alignment pin, axially and radially the positioning of offside spherical bearing.
Preferable, the tool locating ring comprises:
Locating ring and frock support, the frock support is welded on the locating ring.
Preferable, the material of frock support is an angle steel.
In the above-described embodiments, the side bearing is installed on the driftage gear ring through the frock carriage, and is connected with the tool locating ring through alignment pin, and frock carriage, tool locating environmental protection have been demonstrate,proved the side bearing circumferentially and position radially.When the sideshake between side friction sheet and the driftage gear ring is uneven; Can guarantee that sideshake is in satisfactory scope through adjustment frock carriage and tool locating ring; The wearing and tearing and the driftage noise of the side friction sheet that is installed on the bearing of side have been reduced; Guarantee the steady driftage of wind power generating set, avoided repeatedly dismantling of side bearing, thereby saved construction cost from mainframe; Can reduce simultaneously the radial deflection of wind generating set engine room, reach fatigue wear, the broken teeth phenomenon of yaw drive and driftage gear ring tooth, improve the meshing efficiency of tooth.
