Description
Technical Field
The utility model relates to the field of wind power gearboxes, in particular to a repairing device on a bearing hole tower of a parallel-stage box body of a wind power gearbox.
Background
With the development of the wind power industry, the service life of the wind power gear box is longer and longer, and the conditions of maintenance and repair of the wind power gear box on a tower are more and more common. Among all fault types, the fault conditions of slipping wear between the bearing and the bearing bore are very common. After slipping and wearing occurs between the bearing and the bearing hole, the bearing hole is worn into an irregular round or oval shape, a gap is generated between the bearing and the bearing hole, and the bearing hole can not play an effective role in centering and supporting the bearing. And along with the continuous operation of the gear box, the abrasion condition can be more and more serious, the bearing center and the bearing hole deviate more and more, and meanwhile, the rotating shaft assembled with the bearing can not rotate around a fixed circle center, so that the normal operation of the rotating shaft is influenced, the damage of other related parts on the rotating shaft is further aggravated, the gear box is finally damaged, and the normal operation is not realized.
At present, on a wind power gear box, after a bearing hole is subjected to slipping and abrasion, the gear box is maintained on a tower firstly due to the fact that the maintenance cost of returning the gear box to a factory is too high.
A maintenance method is that the glue is applied and cold melting is carried out
The defects of the glue beating and cold melting treatment are as follows:
1. The difference between the glue or cold-melted material and the box body is large, and the precision of the bearing hole cannot be ensured.
2. When the abrasion loss is large, the adhesiveness of the glue or the cold-soluble material cannot be guaranteed, and the glue has failure risk.
Another maintenance method is a single cantilever aerial boring technique: the blade-side bearing holes are machined using the motor-side bearing holes as a reference with single cantilever support.
The single cantilever aerial boring technique has the disadvantages that:
1. it is necessary to base the motor-side bearing hole. If the motor side bearing hole wears, accurate positioning is not possible.
2. The coaxiality error exists between the motor side bearing hole and the blade side bearing hole, and the single cantilever air boring technology is extended by a single support, so that the boring precision cannot be ensured.
3. The wear of the motor-side bearing hole cannot be maintained.
