Abstract
The utility model discloses a motor transmission shaft. The motor transmission shaft comprises a working section shaft which is connected with an impeller and is made of a stainless steel material, and a motor section shaft which is connected with a motor and is made of a 45-stainless steel material; an inner hole provided with internal threads is formed in the center of the cross section of the motor section shaft; a bolt which is matched with the inner hole in size and is provided with external threads is formed in one end of the working section shaft; the working section shaft is screwed on the motor section shaft through the bolt; and the motor section shaft and the working section shaft are welded. According to the motor transmission shaft, the rust resistance of the shaft is improved and the service life of the motor is prolonged on the premise of changing the mechanical performance and the properties of the motor as slightly as possible; and the two sections of shafts are connected by combining threaded connection and welding, so that the stress concentration on the shafts is reduced, and the mechanical performance of the shafts is guaranteed.
Description
Technical field
The utility model relates to a kind of motor transmission shaft.
Background technique
Traditional electrical arbor intensity is higher, but due to the particularity of technique, on motor shaft, connecting impeller place can be in the more intense bad border of high temperature, corrosion, traditional electrical arbor rust resistance is general, cause its corrosion serious, cause the replacement frequency of motor higher, increased human cost and the equipment cost of maintenance.Cause that current of electric is excessive if motor shaft is replaced with stainless steel, motor cannot normally be worked.
Model utility content
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, can keep original mechanical property, high temperature resistant and rust stable motor transmission shaft again.
To achieve these goals, the technological scheme that the utility model adopts is:
A kind of motor transmission shaft, comprise the motor section axle that the active section axle of the stainless steel material formation being connected with impeller and 45 Steel materials that are connected with motor form, the cross-section center place of described motor section axle is provided with tapped endoporus, one end of described active section axle is provided with described interior hole size matches and is with externally threaded bolt, described active section axle is screwed on described motor section axle by described bolt, and the connection seam crossing of described motor section axle and active section axle is welded to connect.
Owing to adopting such scheme, the motor shaft of this device is made up of the motor section axle of 45 Steel materials and active section axle two-part of stainless steel material, the tapped endoporus arranging by motor section axle axle cross-section center place is connected with the externally threaded bolt of being with of active section axle, thereby existing motor transmission shaft non-refractory, not corrosion resistant problem are solved, the joint that connects rear motor section axle and active section axle is welded, thereby strengthen the effect connecting, guaranteed the mechanical property of axle.
In sum, this device has improved the rust resistance of axle under the mechanical property of as far as possible little change axle and the prerequisite of the performance of motor own, and the working life of motor, the Placement of two sections of axles adopts and is threaded and welds the mode combining, the stress reducing on axle is concentrated, and has guaranteed the mechanical property of axle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is erection drawing of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As shown in Figure 1 and Figure 2, a kind of motor transmission shaft, comprise the motor section axle 2 that the active section axle 3 of the stainless steel material formation being connected with impeller and 45 Steel materials that are connected with motor form, the cross-section center place of described motor section axle 2 is provided with tapped endoporus 4, one end of described active section axle 3 is provided with described interior hole size matches and is with externally threaded bolt 1, described active section axle is screwed on described motor section axle 2 by described bolt 1, and connection seam 5 places of described motor section axle 2 and active section axle 3 are welded to connect.
