Abstract
The utility model discloses a motor, which comprises a support. A machine shell is fixed on the support, an opening is arranged on the connection end face of the machine shell, a hollow motor shaft is installed in the machine shell in rotating mode, the connection end of the motor shaft is sleeved at the position of the opening, and a key groove is arranged on the annular inner wall of the motor shaft. The motor is simple in design and convenient to use and assemble, can effectively ensure that a pump shaft and the motor shaft are concentric, and meets use requirements of enterprises.
Description
Technical field:
The utility model relates generally to technical field of motors, relates in particular to a kind of electric machine structure.
Background technology:
At present, the syndeton of motor and oil pump is: motor adopts vertical installation or horizontal installation, and fixes through connecting base, and motor is connected with oil pump through shaft coupling then.Shaft coupling one end is connected with oil pump, and the other end links to each other with motor shaft, and is middle through the key connection.For the mount that guarantees oil pump and servomotor same in the heart; Can add the oil pump Connection Block; Be easy to guarantee that from fit on the mount of oil pump and servomotor guarantees easily that also oil pump and servomotor are concentric in the heart same like this, this syndeton is comparatively practical; But, seem comparatively complicated and expensive from assembling and production cost.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of motor to be provided, and it is simple in structure, is convenient to assembling.
The utility model is realized through following technical scheme:
A kind of motor includes bearing, is fixed with casing on the bearing; It is characterized in that: said casing connects end face and is provided with opening; Be rotatablely equipped with hollow motor shaft in the casing, the link of motor shaft is placed in described opening, and the annular inner wall of motor shaft is provided with keyway.
A kind of motor is characterized in that: said keyway is the flat key groove.
When the utility model and oil pump assembling, need the pump shaft of oil pump be provided with flat key.During operation, the pump shaft of oil pump is inserted in the described motor shaft, flat key is corresponding to be inserted in the described flat key groove, makes the pump shaft of oil pump be able to be fixedly connected with the motor shaft of motor, has guaranteed between the two concentric.
The utility model has the advantages that:
The utility model structural design is simple, and is easy to use, is convenient to assembling, and can effectively guarantee between pump shaft and the motor shaft with one heart, satisfied the user demand of enterprise.
