Abstract
The utility model discloses a kind of dynamo steel rotor, relate to machinery manufacturing technology field; It comprises motor shaft and rotor body, and described rotor body is the steel bushing of hollow, and its one end is connected with front rotor endcap, and the other end is connected with rear rotor tooth disk cover; Described front rotor endcap and described rear rotor tooth disk cover are all socketed on described motor shaft.Described front rotor endcap and described motor shaft are interference fit, and described rear rotor tooth disk cover is connected by key with described motor shaft.The material of described rotor body is 45 steel or 20 steel.The utility model can solve the rotor manufactured materials of prior art costly, complex process and the low problem of production efficiency.
Description
Technical field
The utility model relates to machinery manufacturing technology field, especially a kind of steel rotor being applied to motor.
Background technology
In traditional motor rotor component, rotor body many being installed on by many silicon steel punched chips superimposedly on motor shaft is formed, the silicon steel sheet two ends of closed assembly are clamped by rotor end plates again, be bolted, then to coordinate with motor shaft with center seam thus be formed as holistic rotor, for key is connected between motor shaft with rotor.In the rotor of this structure, silicon steel punched chip need come shaping with stamping die punching silicon steel sheet, and costly, and the closed assembly of silicon steel punched chip need use artificial closed assembly for diel and silicon steel material, more time-consuming.
Utility model content
The purpose of this utility model is to provide a kind of dynamo steel rotor, and it can solve the rotor manufactured materials of prior art costly, complex process and the low problem of production efficiency.
In order to solve the problem, the technical solution adopted in the utility model is: this dynamo steel rotor, includes motor shaft and rotor body, and described rotor body is the steel bushing of hollow, and its one end is connected with front rotor endcap, and the other end is connected with rear rotor tooth disk cover; Described front rotor endcap and described rear rotor tooth disk cover are all socketed on described motor shaft.
In technique scheme, more specifically scheme is: described front rotor endcap is welded on the one end in described rotor body cover, and described rear rotor tooth disk cover is welded on the other end in described rotor body cover; Described front rotor endcap and described motor shaft are interference fit, and described rear rotor tooth disk cover is connected by key with described motor shaft.
Further: the material of described rotor body is 45 steel or 20 steel.
Owing to have employed technique scheme, the utility model compared with prior art has following beneficial effect:
1, rotor body of the present utility model can directly be processed by 45 or 20 thick walled steel tube trucks, and overall weight alleviates and material therefor low price greatly, reduces material cost.
2, motor rotor component of the present utility model is welded by rotor body and front rotor endcap and rear rotor tooth disk cover, the processing of each assembly is based on machined into, and welding and Vehicle Processing technique are all comparatively ripe technique, process and packaging efficiency high, production cost greatly declines.
3, the utility model rotor is coordinated by endoporus seam, and connecting portion welds, and to be only connected with flat key with the cooperation of endoporus seam more surely to lean on than former rotor.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the rotor of prior art, rotor body 1 is installed on by many silicon steel punched chips as shown in Figure 2 and superimposedly on motor shaft 3 forms, the silicon steel sheet two ends of closed assembly are clamped by rotor end plates 2 again, fixed by bolt 4, then to coordinate with motor shaft with endoporus seam thus be formed as holistic rotor.
The dynamo steel rotor of Fig. 3 to Fig. 6, its rotor body 1 is the steel bushing of hollow, and the one end in rotor body 1 overlaps is welded with front rotor endcap 5, and the other end in cover welds with rear rotor tooth disk cover 6; Front rotor endcap 5 and rear rotor tooth disk cover 6 are all socketed on motor shaft 3.Front rotor endcap 5 is interference fit with motor shaft 3, and rear rotor tooth disk cover 6 is connected by key 7 with motor shaft 3, and key 7 is flat key.The material of rotor body 1 is 45 steel, can be 20 steel or other mild steel in other embodiments.Rotor body 1 is directly processed by 45 thick walled steel tube trucks.
