Abstract
The utility model discloses an explosion-proof motor rotor shaft which comprises a body. The body comprises a first circular shaft section. One end of the first circular shaft section is a second circular shaft section which is connected with a spline section in a welding mode, and the other end of the first circular shaft section is a third circular shaft section. The hardness of the spline section is HRC 35-40. The second circular shaft section and the first circular shaft section are connected with the third circular shaft section through welding. The length of the body is above 600 millimeters. Compared with the prior art, the explosion-proof motor rotor shaft increases the hardness of parts, strengthens bearing capacity, and greatly improves precision of the parts.
Description
Technical field
The utility model relates to a kind of parts of anti-explosion motor, relates in particular to a kind of anti-explosion motor rotor shaft.
Background technique
Anti-explosion motor is a kind ofly can at the employed motor of inflammable and explosive factory, not produce electrical spark during operation.Anti-explosion motor is mainly used in colliery, petroleum gas, petrochemical industry and chemical industry.In addition, also be widely used in departments such as weaving, metallurgy, town gas, traffic, grain and oil processing, papermaking, medicine.The anti-explosion motor rotor shaft, as the core component of anti-explosion motor, its performance is directly connected to the running of body.The axis body of anti-explosion motor rotor shaft generally includes circular shaft section and spline segment, and spline segment is normally made by the technique of milling or gear hobbing.There is following shortcoming in existing anti-explosion motor rotor shaft, and the easy bending deflection of axis body is difficult to ensure that motor runs well.In addition, difficulty of processing is large, cuts processing diameter transition place easy-rupturing, and whole yielding, the moment of torsion ability to bear is low, easily become fragile after the welding processing, and lower hardness, precision also decreases.
Therefore, in order to overcome the defects that exists in the prior art, be necessary existing anti-explosion motor rotor shaft is improved.
