Abstract
The invention discloses a motor which comprises a support, wherein a shell is fixed on the support; an opening is formed on a shell connection end surface; a hollow motor shaft is rotatably mounted in the shell; a connection end of the motor shaft is sleeved at the opening part; and a key groove is arranged on the annular inner wall of the motor shaft. The motor disclosed by the invention has a simple structure, is convenient to use and assemble and can effectively ensure the concentricity between the pump shaft and the motor shaft, thereby meeting the using requirements of enterprises.
Description
Technical field:
The present invention 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.
Summary of the invention:
The object of the invention 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 present invention realizes 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 present invention 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.
Advantage of the present invention is:
Structural design of the present invention 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.
Description of drawings:
Fig. 1 is a front view of the present invention.
Fig. 2 is a left view of the present invention.
Embodiment:
Referring to accompanying drawing.
A kind of motor includes bearing 1, is fixed with casing 2 on the bearing 1; Casing 2 connects end face and is provided with opening 3; Be rotatablely equipped with hollow motor shaft 4 in the casing 2, the link of motor shaft 4 is placed in described opening 3 positions, and the annular inner wall of motor shaft 4 is provided with flat key groove 5.
Claims (2)
1. a 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.
2. a kind of motor according to claim 1 is characterized in that: said keyway is the flat key groove.
