Abstract
The utility model relates to a motor shaft mainly used for a pumping unit in an oil field. The motor shaft comprises a main body which is a cylinder; the diameters of cross sections of two ends of the main body are smaller than that of the cross section of the middle part thereof; and the main body is provided with a key slot. The motor shaft has the advantages of reasonable structural design, high production precision and small usage error.
Description
Technical field
The utility model relates to a kind of motor shaft, is mainly used in the pumping-unit motor in oil field.
Background technique
Motor shaft is mainly used in the drive motor on the screw pump pumping unit, and the volume of screw pump pumping unit has reduced much compared to original pump housing volume at present, and the bind mode between motor and the screw pump is directly to drive, in requisition for supporting motor shaft.But because the change of driving mode is had higher requirement to the motor machining accuracy, the production to motor shaft in the prior art exists certain defective, uses time error bigger.
The model utility content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and provides a kind of reasonable in design, production precision height, the motor shaft that use error is little.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of motor shaft, comprise main body, and it is characterized in that: described main body is a cylindrical body, the diameter of main body two ends cross section is less than the diameter of cross section in the middle of the main body; Have keyway on the main body.
The material of main body described in the utility model is a steel.
The utility model compared with prior art has following positive effect: reasonable in design, and production precision height, use error is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 main body, 2 keyways.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1, present embodiment mainly is made up of main body 1, and main body 1 is a cylindrical body; The diameter of main body 1 two ends cross section is smaller, and to the stepped increase gradually in centre, is convenient to the utility model is installed in the pump housing; The centre of main body 1 has keyway 2.
The material of main body is a steel in the present embodiment, when production and processing, earlier material is machined, and the profile of main body 1 is worn in processing; After heat-treating typing, mill processing again, form keyway 2; Grind processing at last, can prevent the distortion that product is caused effectively like this in heat treatment process, the error when reducing to use improves product percent of pass.
In addition, need to prove, specific embodiment described in this specification, as long as the undeclared concrete shape and size of its part, then this part can be Any shape and the size that adapts with its structure; Simultaneously, the part title of getting also can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
Claims (2)
1. a motor shaft comprises main body, it is characterized in that: described main body is a cylindrical body, and the diameter of main body two ends cross section is less than the diameter of cross section in the middle of the main body; Have keyway on the main body.
2. motor shaft according to claim 1 is characterized in that: the material of described main body is a steel.
