Abstract
The utility model discloses a conveniently changed motor bearing set, solving the problem of changing bearings of a wind driven generator. The conveniently changed motor bearing set comprises a bearing block (1), wherein a bearing inner cover (3) is arranged on the right side of the bearing block (1); a bearing outer cover (2) is arranged on the left side of the bearing block (1); the bearing outer cover (2), the bearing block (1) and the bearing inner cover (3)are fixedly connected together by screws (11) sequentially; deep groove ball bearings (17) are arranged in the bearing block (1) on the left side of the bearing inner cover (3); cylindrical roller bearings (16) are arranged in the bearing block (1) on the left sides of the deep groove ball bearings (17); oil throw rings (4) are arranged in the bearing block (1) on the left sides of the cylindrical roller bearings (16); and a seal ring (14) is arranged between the oil throw rings (4) and the bearing outer cover (2). By adopting the conveniently changed motor bearing set disclosed by the utility model, the problem of changing the bearings of the wind driven generator in a cabin is solved and the operation cost is saved.
Description
Technical field
The utility model relates to a kind of bearing group of generator, particularly a kind of removable bearing group of wind-driven generator.
Background technology
Motor is in operation process, and bearing bears radial and axial load.After the motor long-time running, need change the bearing of wearing and tearing.When prior art is changed the bearing of motor; Need the end cap of motor all be unloaded, this operation particularly is very difficult for the large scale wind motor, because; In a single day wind-driven generator is installed in the cabin; Just be difficult to take out, even if can take apart, the cost cost is also quite expensive again; Moreover the space is limited in the cabin, can not use large-scale lifting appliance, makes can't carry out the dismounting of the end cap of motor.
Summary of the invention
The utility model provides a kind of conveniently replaced motor bearings group to solve the problem that the bearing of wind-driven generator is changed.
The utility model overcomes the above problems through following scheme:
A kind of conveniently replaced motor bearings group; Comprise bearing pedestal; The right flank of bearing pedestal is provided with internal bearing cover, and the left surface of bearing pedestal is provided with bearing end cover, and screw is fixed together bearing end cover, bearing pedestal and internal bearing cover successively; In the bearing pedestal in the left side of internal bearing cover, be provided with deep groove ball bearing; In the bearing pedestal in the left side of deep groove ball bearing, be provided with cylinder roller bearing, between deep groove ball bearing and cylinder roller bearing, be provided with first packing ring and second packing ring, in the bearing pedestal in the left side of cylinder roller bearing, be provided with flinger; Between flinger and bearing end cover, be provided with sealing ring, the lateral surface of bearing end cover is provided with second sealing ring.
Be provided with sleeve pipe in the fixing hole on the cylindrical of bearing pedestal; Screw bolt passes pad, first bolt washer, second bolt washer and sleeve pipe and motor cabinet are fixed together; Between bearing pedestal and motor cabinet, be provided with insulating trip, bearing end cover is provided with the lubricating oil insulating joint.
The utility model just can be changed the bearing of motor easily under the situation of using simple lifting and support equipment, solved the difficult problem of motor replacing bearing in the cabin, has saved the work funds.
