Abstract
The invention provides a rolling machining structure of a motor rotor. The rolling machining structure of the motor rotor comprises a rotary shaft. The rotary shaft is sleeved with a rotor iron core, and shaft head auxiliary tools are installed on shaft heads at the two ends of the rotary shaft respectively. The shaft head auxiliary tools are composed of cylindrical lateral walls and round bottom faces, and mounting holes are formed in the bottom faces. The shaft heads of the rotary shaft are sleeved with the shaft head auxiliary tools, and the bottom faces are fixed with the shaft heads of the rotary shaft in the mode that bolts penetrate through the mounting holes. The rotary shaft is placed on two idler wheel shelves through the shaft head auxiliary tools at the two ends of the rotary shaft, and the lateral walls of the shaft head auxiliary tools make contact with the idler wheel shelves. According to the rolling machining structure of the motor rotor, the shaft head auxiliary tools are fixed outside the shaft heads, the situation that the rotor can rotate stably and safely on idler wheels is guaranteed, contact and friction between the rotary shaft and the idler wheels are effectively avoided, the precision of the rotary shaft is better protected and the bearing assembling quality is improved.
Description
Technical field
The present invention relates to motor, relate in particular to epitrochanterian rotating shaft is directly placed on to the processing structure that rolls and manufacture on roller.
Background technology
High speed development along with building, metallurgy, chemical industry, the utilization of motor is more and more wider, and motor is in manufacture process, and most of rotors are directly placed on rotating shaft on roller and roll and manufacture, easily occur that axis friction is impaired, after must repairing, just can carry out bearing assemble.In order to reduce friction, traditional method is that roller is manufactured to nylon sleeve or inlays copper sheet in roller surface, and these two kinds of methods can not be avoided the pivoting friction between rotating shaft and roller completely, and can not guarantee the steady placement of rotor on roller.
Summary of the invention
For existing processing mode, can cause axis friction impaired, and rotor is placed the shortcomings such as not steady, applicant is studied improvement, and a kind of rolling processing structure of rotor is provided, and can effectively avoid rotating shaft before bearing assemble, to rotate the appearance of the problems referred to above such as wearing and tearing.
Technical scheme of the present invention is as follows:
A rolling processing structure, comprise rotating shaft, in described rotating shaft, be set with rotor core, on the spindle nose at rotating shaft two ends, be separately installed with spindle nose auxiliary mould; Described spindle nose auxiliary mould is comprised of the sidewall of tubular and circular bottom surface, offers installing hole on bottom surface; Spindle nose auxiliary mould is set on the spindle nose of rotating shaft, and by installing hole, the spindle nose of bottom surface and rotating shaft is installed fixing by bolt; Rotating shaft is placed on two roller shelves by the spindle nose auxiliary mould at two ends, and the sidewall of spindle nose auxiliary mould contacts with roller shelf.
Its further technical scheme is: the distance between described two roller shelves is consistent with the length of rotating shaft.
Useful technique effect of the present invention is:
The present invention takes into full account rotating shaft direct placement on roller can cause the shortcomings such as rotating shaft pivoting friction is impaired, rotor placement is not steady; by the design to spindle nose auxiliary mould; can guarantee that rotor is steady on roller, safety is rotated; effectively avoid the contacting of rotating shaft and roller, friction; better protection rotating shaft precision, improves bearing assemble quality.
The aspect that the present invention is additional and advantage will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of spindle nose auxiliary mould.
Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes rotating shaft 5, in rotating shaft 5, be set with rotor core 4, the common rotor that forms of rotating shaft 5 and rotor core 4.The two ends of rotating shaft 5 are spindle nose, are separately installed with spindle nose auxiliary mould 3 on spindle nose.The structure of spindle nose auxiliary mould 3 is referring to Fig. 2 and Fig. 3, and its sidewall 3-1 by tubular and circular bottom surface 3-2 connect to form, and in the contact position of sidewall 3-1 and bottom surface 3-2, carry out spot welding.On the 3-2 of bottom surface, be processed with the several installing hole 3-3s consistent with screwed hole position on rotating shaft 5 spindle noses and quantity.As shown in Figure 1, spindle nose auxiliary mould 3 is set on the spindle nose of rotating shaft 5, the spindle nose of rotating shaft 5 stretches in 3 of spindle nose auxiliary moulds.With bolt 2, by installing hole 3-3, screw in the screwed hole on rotating shaft 5 spindle noses, the spindle nose of the bottom surface 3-2 of spindle nose auxiliary mould 3 and rotating shaft 5 is installed fixing.According to the distance of 1 of two roller shelf of length adjustment of rotating shaft 5, rotor is steadily placed to roller shelf 1 together with 3 handlings of spindle nose auxiliary mould, rotating shaft 5 is placed on two roller shelves 1 by the spindle nose auxiliary mould 3 at two ends, and the sidewall 3-1 of spindle nose auxiliary mould 3 contacts with roller shelf 1.
The present invention adopts at rotating shaft 5 spindle noses fixing spindle nose auxiliary mould 3 outward, and frock manufacture is simple, easy installation and removal, and protection that can better countershaft 5, greatly reduces the bearing assemble quality problems that cause because of rotating shaft wearing and tearing.When rotor rotates, spindle nose auxiliary mould 3 rotates on the roller of roller shelf 1, can reduce the rotation of rotating shaft before bearing assemble wearing and tearing or injured, guarantees the precision of rotating shaft.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
