Abstract
The invention discloses an anti-fracture structure of a rib-welded shaft motor. The anti-fracture structure comprises a shaft, a rib plate and lantern rings, wherein the lantern rings are arranged at two ends of the shaft; lantern ring grooves and positioning holes are formed in the lantern rings; and the rib plate is arranged in the lantern ring grooves. By adopting a method for adding the lantern rings, the influence of welding heat is reduced to the lowest level, and the method is combined with the reinforcing plate and a heat treatment technology which are widely used at present, so that the shaft is effectively prevented from being fractured, and the safety and the reliability of the anti-fracture structure are improved.
Description
Technical field
The present invention relates to machine field, relate in particular to a kind of anti-fracture structure of welding the muscle shaft motor.
Background technique
Medium-sized or above AC and DC motor is used on a kind of axle weldering width of cloth muscle structure usually, is not only in order to set up the axial ventilation road and is convenient to heat exchange, and can effectively reduce the rotor punching consumption, reduces weight not increasing in the diameter of axle situation, guarantees rigidity and intensity.Welding heat affected zone changes the material crystals tissue, lack of penetration and postweld heat treatment and welding residue etc. all can produce defective makes apart from the weld joint (especially gusset end axis cross section) to have pre-crackle, under the torque of motor long-term load, because of repeated strain inefficacy final fracture.Adopt at present anti-fracture method multiple, mainly concentrate on heat treatment process, the gusset end structure is designed to discharge stress structure, releases at axle and puts the stress groove, manual bag weldering gusset end etc.
Summary of the invention
The purpose of this invention is to provide a kind of anti-fracture structure of welding the muscle shaft motor, the heat affecting when it can effectively improve gusset and axle welding, construction technology is simply efficient simultaneously.
The present invention is achieved in that the anti-fracture structure of a kind of weldering muscle shaft motor, comprises axle, gusset, the collar, and it is characterized in that: the axle two ends are provided with the collar, is provided with cover ring groove, positioning hole on the described collar, is provided with gusset in the described cover ring groove.
Further, the contact position of described gusset and axle, gusset and the collar welds respectively.
The present invention makes the welding heat affected minimum that is reduced to by adopting the method that increases the collar, combines with the gusset and the heat treatment technology that extensively adopt at present again, can effectively prevent axle fracture, improves the structural safety reliability.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, axle, 2, gusset, 3, the collar, 4, the cover ring groove, 5, positioning hole, 6, positioning screwn.
Embodiment
The invention will be further described below in conjunction with accompanying drawing
The anti-fracture structure of a kind of weldering muscle shaft motor, comprise axle 1, gusset 2, the collar 3, cover ring groove 4, positioning hole 5, positioning screwn 6, during implementation of the present invention, to there be the collar 3 that overlaps ring groove 4 and positioning hole 5 to be enclosed within the two ends of axle 1 by Spielpassung, after ring grooves 4 aligns vertically with two covers, usefulness positioning screwn 6 lock-bits; Then gusset 2 is snapped in vertically in the cover ring groove 4, weld respectively the contact position of axle 1 and gusset 2, gusset 2 and the collar 3, at last positioning screwn 6 and the collar 3 are welded, and the collar 3 does not weld with axle 1 among the present invention, can effectively reduce the welding heat affected possibility that pre-crackle is produced, the described collar 3 gets final product radial location gusset 2, can avoid again the heat affected zone that produces when gusset 2 terminations and axle 1 welding.
