Preferably, the rotor contact round steel plate, the end cover round steel plate and the cylinder are of an integrally formed structure.
Preferably, the axial length of the cylinder is greater than that of the rotor shaft end, the rotor contact steel plate is axially separated from the end face of the rotor shaft end and is not in contact with the end face of the rotor shaft end, and the rotor contact steel plate is connected with a connecting hole in the end face of the rotor shaft end through a first bolt arranged axially.
Preferably, the first bolt is sleeved with a counter-locking nut, and the cylinder is provided with a notch which is radially aligned with the first bolt and is used for screwing the counter-locking nut.
Preferably, the surface of the end cover contact round steel plate, which is attached to the end cover of the rotor shaft end, is pasted with a protective elastic pad, and the end cover contact round steel plate is connected with the end cover of the rotor shaft end through a second bolt arranged along the axial direction.
Preferably, the inner wall of the cylinder is a protective soft layer, and the protective soft layer is in clearance fit with the shaft end of the rotor.
The utility model has the advantages that:
1. the utility model discloses a bearing protection frock in motor shipping process is fixed with rotor contact round steel board and rotor axle head end face, it is fixed with rotor axle head end cover with end cover contact round steel board to connect rotor contact round steel board and end cover contact round steel board with the drum, because rotor axle head end cover is fixed with the bearing, consequently with rotor contact round steel board, drum and end cover contact round steel board with rotor and bearing even one-tenth an organic wholely, can effectively prevent the relative drunkenness of rotor and bearing in the transportation, the drum cover is served at the rotor axle in addition, can effectively protect the rotor axle head.
2. The axial length of drum is greater than the axial length of rotor axle head, rotor contact steel sheet separates contactless along the axial with rotor axle head terminal surface, make the rotor axle head of the adaptable different length of frock, improve the commonality and the practicality of frock, and through set up the breach that radially aligns with bolt in the drum, stretch into from the breach and will turn over lock nut and fasten to on rotor contact round steel sheet soon, can effectively avoid the not hard up of bolt in the motor transportation, improve the structural reliability, thereby improve the protection reliability of frock.
3. The protective elastic pad is pasted on the surface of the end cover contacting the round steel plate and attached to the end cover of the rotor shaft end, the friction force between the protective elastic pad and the end cover of the rotor shaft end is increased, the radial play between the bearing and the rotor in the transportation process is effectively buffered, the relative vibration between the bearing and the rotor is reduced through the elastic buffering of the protective elastic pad, and the protection reliability is further improved.

Detailed Description
The following describes an embodiment of the present invention in detail with reference to fig. 1.
Bearing protection frock of motor shipment in-process, its characterized in that include with rotor shaft end terminal surface laminating fixed rotor contact round steel board 1, with rotor shaft end cover laminating fixed end cover contact round steel board 2, contact round steel board 1 and end cover round steel board 2 connect through drum 3, 3 covers of drum are served at the rotor shaft.
Above bearing protection frock in motor shipment process, it is fixed with rotor axle head terminal surface with rotor contact round steel plate 1, it is fixed with rotor axle head end cover with end cover contact round steel plate 2, and connect rotor contact round steel plate 1 and end cover contact round steel plate 2 with drum 3, because rotor axle head end cover is fixed with the bearing, consequently through rotor contact round steel plate 1, drum 3 and end cover contact round steel plate 2 with rotor and bearing even become an organic whole, can effectively prevent the relative drunkenness of rotor and bearing in the transportation, and drum 3 covers on the rotor axle holds, can effectively protect the rotor axle head.
The rotor contact round steel plate 1, the end cover round steel plate 2 and the cylinder 3 are of an integrally formed structure. The integrated structure has better structural stability and is reliable and firm.
The axial length of the cylinder 3 is greater than that of the rotor shaft end, the rotor contact steel plate 1 is axially separated from the end face of the rotor shaft end and is not in contact with the end face of the rotor shaft end, and the rotor contact steel plate 1 is connected with a connecting hole of the end face of the rotor shaft end through a first bolt 4 arranged along the axial direction. The axial length of drum 3 is greater than the axial length of rotor axle head, and rotor contact steel sheet 1 separates contactless along the axial with rotor axle head terminal surface for the adaptable different length's of frock rotor axle head improves the commonality and the practicality of frock.
Wherein, the bolt I4 is sleeved with a reverse locking nut 5, and the cylinder 3 is provided with a notch 31 which is radially aligned with the bolt I4 and is used for screwing the reverse locking nut 5.
